Lathe mandrel that has lengthwise slots and a spring steel sleeve. To use this, the smaller end of the mandrel is pressed into place in the hole with an arbor press. To expand the sleeve tightly against the inside of the hole, a tapered pin is put inside the sleeve.
Also called an expansive bit, this drill bit has a cutter head mounted at right angles to the shank of the bit that is moveable in relation to the shank and to change the diameter of the hole that is being bored.
Bolt and expandable sleeve which is used to fasten masonry by inserting the unit into a drilled hole in the masonry and then tightening it which causes a wedge which expands the sleeve into the hole for a snug fit.
1. Strips of rubber or flexible material used to separate units of concrete. Because the strips are compressed, they give the concrete room to expand with temperature changes, thus preventing cracking.
2. A flexible piece of metal used between gypsum wallboard panels to prevent buckling when temperature changes cause the panels to expand.
A thermostatically controlled valve, which controls the liquid refrigerant as it passes through, and cooling it to the temperature in the evaporator. The diaphragm, which seals the tube to the chamber on the expansion valve, is attached on the valve stem, which is pushed toward closed by a spring. When the temperature of the line rises, the refrigerant in the bulb, tube and upper chamber allows the spring to open the expansion valve. More refrigerant is allowed into the evaporator once the expansion valve is opened. This valve works in response to the cooling load demand on the evaporator.
Also called an expansion bit, this drill bit has a cutter head mounted at right angles to the shank of the bit that is moveable in relation to the shank and to change the diameter of the hole, which is being bored.
A comparison of operating expenses to potential gross income. This ratio can be compared over time and with that of other properties to determine the relative operating efficiency of the property considered.
1. Person or business susceptible to loss on an investment, such as a high- risk speculation.
2. The advertising, whether free or paid, of property that is for sale.
3. Open to the elements, unhidden from view.
