  • Patent number: 4901585
    Abstract: Disclosed is a method and apparatus for directly measuring the radially applied, compressive nip load between two press rolls. Matched, low angle ramp plates are connected tensilely by a load strip which supports a strain gauge. The assembly, having less than one inch of nip section thickness, is placed in the subject roll nip and loaded normally. Due to the ramp angle base, the two plates are displaced in opposite directions normal to the radial load. The connective load strip opposes the opposite displacement thereby stressing the strain gauge.

  • Patent number: 4165146
    Abstract: An electrical wiring device, which may be an incandescent lamp socket, receptacle, switch, pilot light or any other wiring device intended for mounting in an opening of a metal sheet, has a mounting means of the snap-in spring type, including divergent spring arms formed with sheet engaging elements on their free ends, that have serrations adapted to engage opposed corners of the mounting opening formed in the metal sheet or plate in which the wiring device is to be supported. The serrations differ from conventional types used in springs of this type in that the portion of the spring arm in which the serrations are formed has a centrally depressed area which offsets inwardly, from the general plane of the teeth, all but the side edge portions of the portion of the spring arm in which the serrations are formed.
