Abstract: A method and apparatus are disclosed primarily for measuring the linear density of a sliver of fibrous strands (e.g. textile) as they are drawn through a trumpet on a processing machine. The measurement is made by detecting the naturally occurring acoustic emissions or signals generated by the frictional and compressive forces between the fibers and between the fibers and the wall of the trumpet as the sliver is drawn through the trumpet. The intensity of the acoustically emitted signal is proportional to the density of the sliver passing through the trumpet. These acoustic emissions are detected by a microphone which convert the acoustic signals to an electronic signal which is amplified and electronically processed to indicate the density of the sliver and may be used to control the textile machine and furnish diagnostic data.

Actuation of the wire guide causes movement of the wires within their respective channels to alter the centerline spacing thereof. The wire guide is useful for making smooth continuous transitions between production runs of different pitch wire harnesses.

Abstract: Stripping of the outer jacket of miniaturized coaxial cable is achieved through the use of stripping blades which have surfaces dulled to preclude cutting the cable core or ground conductor and yet sever the cable and metalized film from the cable core. The stripping blades have an offset to eliminate the need to orient the cable relative to the ground wire with the dull surfaces having a radius to substantially deform the cable with the cable then being pulled to effect removal of the outer jacket and metallized film. The length of stripping accommodates axial elongation of the core with excess core subsequently being trimmed, thereby resulting in a desired stripped length.

Abstract: Conventional traps often catch animals by the leg rather than killing them outright. This trap utilizes two spring actuated jaws closing upon a base ring but with stops on the base ring maintaining the movable jaws slightly open when sprung so that an animal cannot be caught by the leg. The trip mechanism is such that it can be actuated by pressure upon any part of the pan thus releasing the jaws and killing the animal with a blow to the head or neck area. The spring mechanism is such that if large animals are accidentally caught by the foot, they are able to pull foot free.
