Giving foreclosed properties a clean start
Rick and Kim Melhem, from Pen Argyl, fixes up homes and resells them. This is a historic house at 1248 Howertown Road North Catasauqua . (MONICA CABRERA, Allentown Morning Call / September 23, 2007)
Rick Melhem of Pen Argyl buys properties in foreclosure, fixes them up and then resells them.
He prefers whole house restorations to additions or room renovations. There's a greater feeling of accomplishment, says Melhem, who has done all kinds of construction in his career.
Melhem started in the business, working for his father-in-law, who was in the construction trades.
''He did a lot of high-end commercial work,'' Melhem says. The work required a lot of traveling to New Jersey and New York.
Wanting to travel less, Melhem started Realty Investment in 1983. He does about four or five homes a year.
Melhem jokes that he started doing flips before the Home and Garden Television channel made them popular.
The house he recently restored at 1248 Howertown Road in North Catasauqua is a little more elaborate than his typical flip. He usually does everyday properties that are distressed.
He says competition for such properties has heated up recently, possibly thanks to the television programs.
''You used to be competing with four or five people, now it's like 60 to 70,'' he says.
The house Melhem recently restored on Howertown became a family affair. Melhem's wife, Kim, chose all the lighting fixtures, kitchen appliances and bathroom fixtures.
She selected antique looking lights so they would match the decor.
''The electrician gave her a list of places that had antique fixtures and she didn't buy more than two at any one store,'' Melhem says. ''She definitely spread the wealth.''
Sons, Josh and Ryan, college students, helped with the construction over the summer.
Everyone in the family, including daughter, Chalice, fell in love with the house. ''For a brief time,'' he says, ''we considered buying it for ourselves.''

What is a Ball Valve?
A ball valve, one type of quarter turn valve, is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. When the ball is positioned so that the hole runs the same direction as the passageway, the fluid simply flows through the hole, and the valve is open. However, when the ball is positioned so that the hole is perpendicular to the passageway, the fluid cannot pass through, and the valve is closed. The ball is controlled from outside the valve, often with a handle that is turned 90 degrees, or a quarter turn, back and forth to open and close the valve.
The basic ball valve, described above, is a two-way valve. This ball valve has a single, straight passageway bored through the ball, making two openings: one on each side, an inlet and an outlet. A ball valve can also be a three-way valve if a third hole is bored partially through the ball, until it meets the main hole, forming a T. A three-way ball valve can shut off one or all of the three passageways it connects.
Because of the nature of the ball valve, it does not work well in situations in which fine control of the valve is needed, such as the valve that controls the throttle in a car. However, a ball valve works very well for situations in which a flow needs to be completely shut off, such as the shut-off valve on the main water line in your house. Ball valves also do not tend to develop problems if they are not used for long periods of time; they will still work perfectly when needed again.
There are three different types of ball valve. A full port ball valve offers no flow restriction, which means that when the ball valve is open, the liquid can flow freely through it. This is achieved by making the ball larger than the passage size, so that the hole bored through it can be the same size as the passage. A standard port ball valve does not have an oversized ball, and as a result the hole is one size smaller than the passageway. This presents a small amount of flow restriction as the fluid passes through the ball valve. A reduced port ball valve, on the other hand, has an even smaller ball and an even smaller hole, which creates significant flow restriction as the fluid passes through the valve.

Thermostatic Radiator Valve
A Thermostatic Radiator Valve, (TRV), is a self regulating valve fitted to hot water heating system radiators. The TRV controls the temperature of a room by regulating the flow of hot water to the radiator.
TRVs consist of two parts, a valve that opens or closes to control the hot water flow, and an actuator that controls the opening of the valve. The actuator adjusts the valve opening based on the temperature in the room via a mechanical linkage or pin connected to the valve. The actuator is usually a plastic unit containing a wax plug, the wax plug expands or contracts as the temperature of the room rises or falls. The plastic unit is preset by a screw mechanism that positions the wax plug a set distance from the connecting pin.
As the temperature of the room increases the wax expands, pushing the pin down and restricting the flow of hot water. As the room cools the plug contracts, the pin is let out a little and more heat is admitted into the room. This process, completely self contained and without complex electronic circuitry, keeps the room temperature at a desired constant level.
TRV temperature control is suitable for large rooms or buildings that are not constantly occupied, (such as warehouses and garages), where precise control of the room temperature is not critical. They are subject to fairly wide swings in temperature inside the heated space due to external conditions, e.g. ambient temperature and/or wind velocity and direction, and since their setting is not readily adjusted, once the initial setting is made it is rarely changed.
It should be noted that TRVs should not be used in the same room as one with an electronic thermostat. The operation of the two devices are not compatible and would interfere with each other so that effective temperature control would be lost.

How to Buy a Bathroom Faucet
Since the selection of bathroom faucets is quite big, it is best to decide on your budget before you set out to buy one. A bathroom faucet can cost anywhere from $25 to several hundred to nearly $2000. Know what you can afford to spend before you spend it.
There are three basic types of bathroom faucets from which almost all designs originate. First, there is the centerset style, which consists of a spigot with the water control handle attached to its top or side. Most often, there is only one handle for both hot and cold water. Then, there are single-hole bathroom faucets. These usually have two handles, one for hot and one for cold water, but the handles and the spigot form one unit that is attached to the plumbing through one hole in the sinktop or countertop. The third main style of bathroom faucets are the widespread designs. Widespreads have two handles and a spigot and they are all separate pieces, meaning the sink or counter must have three holes in it to attach each piece.
Once you have decided on the bathroom faucet design that would work best with your bathroom, you should think about what kind of material you want. Often, the material you pick for a bathroom faucet is determined by the color you want. Bronze faucets, of course, have golden or brown tones. On the other hand, nickel and stainless steel faucets are reflective or have gray tones. You can also buy a nickel faucet with brass highlights, so the possibilities are numerous.
The final consideration is overall appearance. The centerset designs tend to be more contemporary looking than either single hole or widespread bathroom faucets. These latter two come in an array of styles for traditional and modern bathrooms. You can find faucets that are rounded and lack any corners, or more angular designs that stand out. Pick the style that best fits your aesthetic and that fits into the bathroom of your dreams.

Check valves
Check valves are often used with some types of pumps. Piston-driven and diaphragm pumps such as metering pumps and pumps for chromatography commonly use inlet and outlet ball check valves. These valves often look like small cylinders attached to the pump head on the inlet and outlet lines. Many similar pump-like mechanisms for moving volumes of fluids around use check valves such as ball check valves.
Check valves are used in many fluid systems such as those in chemical, and power plants, and in many other industrial processes.
Check valves are also often used when multiple gases are mixed into one gas stream. A check valve is installed on each of the individual gas streams to prevent mixing of the gases in the original source. For example, if a fuel and an oxidizer are to be mixed, then check valves will normally be used on both the fuel and oxidizer sources to ensure that the original gas cylinders remain pure and therefore nonflammable.
Some types of irrigation sprinklers and drip irrigation emitters have small check valves built into them to keep the lines from draining when the system is shut off.

Ball valve
A ball valve (like the butterfly valve, one of a family of valves called quarter turn valves) is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle position lets you "see" the valve's position.
Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications (and are often preferred to globe valves and gate valves for this purpose). They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.
The body of ball valves may be made of metal, ceramic, or plastic. The ball may be chrome plated to make it more durable.
There are four general body styles of ball valves: single body, split body, top entry, and welded.
There are four general types of ball valves: full port, standard port, reduced port, and v port.
* A full port ball valve has an oversized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted, but the valve is larger.
* A standard port ball valve is usually less expensive, but has a smaller ball and a correspondingly smaller port. Flow through this valve is one pipe size smaller than the valve's pipe size resulting in slightly restricted flow.
* In reduced port ball valves, flow through the valve is one pipe sizes smaller than the valve's pipe size resulting in restricted flow.
* A v port ball valve has either a 'v' shaped ball or a 'v' shaped seat. This allows the orifice to be opened and closed in a more controlled manner with a closer to linear flow characteristic. When the valve is in the closed position and opening is commenced the small end of the 'v' is opened first allowing stable flow control during this stage. This type of design requires a generally more robust construction due to higher velocities of the fluids, which would quickly damage a standard valve.
* A trunnion ball valve has a mechanical means of anchoring the ball at the top and the bottom, this design is usually applied on larger and higher pressure valves(say 4 inch and above 600 psi and above)
Manually operated ball valves can be closed quickly and thus there is a danger of water hammer. Some ball valves are equipped with an actuator that may be pneumatically or motor (electric) operated. These valves can be used either for on/off or flow control. A pneumatic flow control valve is also equipped with a positioner which transforms the control signal into actuator position and valve opening accordingly.

Good Pot of Coffee
Buy the beans of your choice at a coffee shop or grocery store. If possible, buy freshly roasted coffee from a local roaster. The longer that coffee sits around after roasting, the more the flavor deteriorates, so try to find the freshest coffee available. Most larger towns and even many small towns will have a source for freshly roasted coffee. Unfortunately, higher quality coffee often comes with a higher price tag. Only buy enough coffee for 1-2 weeks.
antique hand-crank grinders don't scorch the beansGrind the beans in the nearby grinder unless you have a grinder at home. It is best to grind immediately before you brew. If you grind beans when you purchase them, make sure to use them as soon as possible. Be sure to grind your beans fine for the best taste in an automatic drip coffee maker: the ground coffee should not look like coffee colored baby powder, but rather like poppy seeds. High-speed electric burr grinders heat up the beans, cooking them while grinding. Using a blade grinder can make a lot of very fine powder in even a coarse grind that can clog the filter and cause grounds to overflow into the pot.
Put a coffee filter in the filter basket. It does not matter if the filter is bleached or natural. Try to go with a better filter as cheap generic filters are more likely to clog.
Measure out the coffee grounds. The standard is 2 Tbsp. for every six ounce cup of coffee or 1/2 cup of ground coffee for each 10 cup pot, but you should adjust it to your own personal tastes. Experiment until you are satisfied. Do not use too little coffee as overextraction of the grounds can lead to bitter coffee.
Add a very small amount of salt to the grounds - a few grains per cup. This will help avoid bitterness in the coffee. Too much will, obviously, make the coffee taste of salt.
Measure cold water, according to the amount of coffee grounds you used, using the lines on the coffee pot. It is very important that the water is cold. If water has a disagreeable odor or is particularly hard, remember that whatever you put in the coffee machine will end up in the pot. It is best to use filtered or bottled water.
Pour cold water into the water basin in the coffee pot.
Put the coffee pot back on the warming plate. Make sure the coffee pot is plugged in. (This is very important!)
no electricity? heat water on the wood stove and pour into the filter basketWait for the coffee to be fully brewed. If you "sneak a cup" early it will not only be fairly strong, but it will increase the bitterness of the rest of the pot due to bitter flavors released later during the brewing process.
Coffee's on!Pour yourself a cup of coffee, add sweetener and creamer if you prefer, and enjoy!

angle valves
A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.
Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel.
Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs.
Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
