| Asphalt cement which has been liquefied by blending with petroleum solvents, as for the RC and MC cutback asphalts; upon exposure to atmospheric conditions the solvents evaporate, leaving the asphalt cement to perform its function.
|
| Asphalt or tar that has been diluted with solvents and oils so the resulting material becomes fluid.
|
| The temperature value or the pressure value at which the control circuit closes.
|
| In roofing installation, the procre to prevent lateral water or moisture entering the insulation where it terminated at the end of the work day; usually a felt strip hot-mopped to the deck and to the insulation edge and to the horizontal insulation surface; at the start of the next days work the strip is taken off.
|
| Temperature value or pressure value at which the control circuit opens.
|
| A device which is attached to gas welding torch to convert it into an oxygen-cutting torch.
|
| That part of an oxygen-cutting torch from which the gases issue.
|
| A nozzle or device used in oxygen cutting for controlling and directing the gases used for preheating and the oxygen used for cutting the metal.
|
| 1. Excavating. 2. Sawing. 3. Slicing.
|
| In hardwoods, a portion of a board or plank having the quality required by a specific grade or for a particular use; obtained from a board by crosscutting or ripping.
|
| Cold Water.
|
| Containing blue or pertaining to blue color.
|

|
| A storm or system of winds that rotate about a center of low atmospheric pressure.
|
| Concrete aggregate where the individual pieces are over 100 pounds.
|
| An apparatus in which charged atomic and subatomic particles are accelerated by an alternating electric field while following an outward spiral or circular path in a magnetic field.
|
| Glass sheet produced by blowing a large, elongated glass cylinder, cutting off its ends, slitting it lengthwise, and opening it into a flat rectangle.
|
| Concrete filled steel pipes or tubes, driven through the ground to reach bedrock and used as a foundation for tall buildings and in underpinning.
|
| The round part of a door lock containing the keyway and rotated by the key to transmit motion to the bolt.
|
| A test to determine the compressive strength of concrete.
|
| Refrigerant Cylinder.
|
| 1. The surface traced by a straight line moving parallel to a fixed straight line and intersecting a fixed planar closed curve. 2. Of a lock, the cylindrical-shaped assembly containing the tumbler mechanism and the keyway. 3. A device which converts fluid power into linear mechanical force and motion; this usually consists of movable elements such as a piston and piston rod, plunger or ram, operating within a cylindrical bore. 4. A closed container for fluids. 5. A portable cylindrical container used for transportation and storage of a compressed gas.
|
| Commutator with contact surfaces parallel to the rotor shaft.
|
| A door lock that can be installed in a cylindrical hole rather than in a mortise; also called a Tubular Lock.
|
| An ogee molding combining a concave curve with a convex curve; when the concave curve is on top and the convex curve is on the bottom it is a cyma recta; see Cyma Reversa.
