| A solar heating or cooling system in which the solar heat is collected outside the building and transferred inside using ducts or piping and fans or pumps.
|
| An indirect waste pipe is a pipe that does not connect directly with the drainage system but conveys liquid wastes by discharging into a plumbing fixture, interceptor, or receptacle which is directly connected to the drainage system.
|
| A welded wire bar support used under a support bar, to provide support for top bars in slabs, joists, or beams; also used to support upper mats of bars in slabs without support bars.
|
| A pipe which is installed to vent a fixture trap and which connects with the vent system above the fixture served or terminates in the open air.
|
| A room or area inside a building or structure where the meters for measuring the usage of water, electricity, or gas are located.
|
| In a boiler, combustion air drawn through the burner or fuel bed by a power driven fan in the flue.
|
| Ability of a magnetic field to produce magnetism in a metal.
|
| A property of an electric circuit by which an electromotive force is induced in it by a variation of current either in the circuit itself or in a neighboring circuit.
|
| Using heat induced by electrostatic and electromagnetic means for baking of finishes.
|
| A brazing process wherein coalescence is produced by the heat obtained from resistance of the work to the flow of induced electric current and by using a nonferrous filler metal having a melting point above 800° F. but below that of the base metals; the filler metal is distributed in the joint by capillary attraction.
|
| An a-c motor which operates on principle of rotating magnetic field; rotor has no electrical connection, but receives electrical energy by transformer action from field windings.
|
| A welding process wherein coalescence is produced by the heat obtained from resistance of the work to the flow of induced electric current with or without the application of pressure.
|
| Electromagnetic induction in a circuit creates a counter or reverse (counter) emf (voltage) as the original current changes; it opposes the flow of alternating current.
|
| A machine in an industrial setting that compacts or compresses materials.
|
| Mechanical or non-mechanical devices used in an industrial setting.
|
| A large fluorescent light fixture used in an industrial setting.
|
| A mechanical device used to lift loads in an industrial setting.
|
| A professional qualified by cation, training, and experience to anticipate, recognize, evaluate, and develop controls for occupational health hazards.
|
| Liquid wastes which result from the processes employed in industrial establishments and which are free of fecal matter.
|
| A heavy duty wood floor made of 2 inch thick decking or of wooden blocks laid on end; very resistant to heavy loads and traffic; also called a Factory Floor.
|
| An analysis of deformations and internal forces based on equilibrium, nonlinear stress-strain relations for concrete and reinforcement, consideration of cracking and time dependent effects and compatibility of strains; the analysis shall represent to suitable approximation the three dimensional action of the shell together with its auxiliary members.
|
| Behavior of an element beyond its elastic limit.
|
| 1. A gas that is not reactive, such as helium or neon; see Noble Gas. 2. In welding, a gas which does not normally combine chemically with the base metal or filler metal.
|
| A nonreactive pigment, filler.
|
| Chemically unreactive.
|
| A concrete pad on which to mount mechanical equipment on vibration isolators, to prevent machinery vibration from being transmitted into the building structure.
|
| A property of matter by which it continues in its present state of rest or uniform motion in a straight line, unless that state is changed by an external force.
|
| The exchange between conditioned room air and outdoor air through cracks and openings in the building enclosure.
|
| Capable of being easily ignited; flammable; the opposite is nonflammable.
|
| A point on a curve at which the curvature is zero; in the elastic curve it is the point of zero moment; usually, the curvature of the curve lying to one side of the inflection point is positive, while to the other side it is negative.
