In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...
External pattress boxes: power and data sockets. A pattress or pattress box or fitting box (in the United States and Canada, electrical wall switch box, electrical wall outlet box, electrical ceiling box, switch box, outlet box, electrical box, etc.) is the container for the space behind electrical fittings such as power outlet sockets, light switches, or fixed light fixtures.
A finishing operation, shaping, cold works the points on the tooth sides to flats. It might be considered as a side swage. This slightly reduces the tooth width but increases the operating time between "fittings". Swaging is a major advance over filing as the operation is faster, more precise and greatly extends the working life of a saw.
A lip wider than the hole prevents it from falling behind the wall, and often features such as cleats/spikes prevent it from rotating when being compressed. A machine screw is screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the hole or behind it (in hollow contexts such as drywall over stud ...
An outlet is defined by the NEC as "a point in the wiring system at which current is taken to utilization equipment". [1] This definition includes receptacles, lighting, motors, etc. Ordinary switches control but do not consume electricity, and therefore are not defined as outlets in this sense.
The normal technical term (in both British and International English) for an AC power socket is socket-outlet, [4] but in non-technical common use a number of other terms are used. In British English the general term is socket, but there are numerous common alternatives, including power point, [5] plug socket, [6] wall socket, [7] and wall plug ...
Thus "fasten using FN7" refers to a fastener that is "find number" 7 in the list. FoS: feature of size: A type of physical feature on a part. An FoS is a feature that can have size associated with it, usually involving the opposition of two surfaces (e.g., the two diametrically opposite sides of a hole wall; the two opposite walls of a slot or ...
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
