Abstract:
A substrate, preferably constructed of a ductile material and a tool having the desired shape of the resulting device for contacting contact pads on a test device is brought into contact with the substrate. The tool is preferably constructed of a material that is harder than the substrate so that a depression can be readily made therein. A dielectric (insulative) layer, that is preferably patterned, is supported by the substrate. A conductive material is located within the depressions and then preferably lapped to remove excess from the top surface of the dielectric layer and to provide a flat overall surface. A trace is patterned on the dielectric layer and the conductive material. A polyimide layer is then preferably patterned over the entire surface. The substrate is then removed by any suitable process.

Abstract:
The device disclosed herein is a removable, wall-mounted stand adapted to support a tire while it is being studded. The stand is reversible to suit available space where installed and is adapted to accommodate a stud gun when not in use, studs, and an automatic stud feeder.
Abstract:
A method of probing an electrical device using a membrane probing system having an improved contact. A membrane probe forms a contact having a ridge with a pair of inclined surfaces defining an acute angle such that, when pressed into an electrical pad of a device to be tested, the ridge penetrates into the electrical pad, shearing away any oxide on the surface of the pad. The device may then be tested.
Abstract:
A chuck assembly for automatically ram feeding large diameter flange studs. A chuck body has a first resilient chuck disposed at one end thereof and a reciprocating second resilient chuck movable through the body from a first loading position past a passageway to which the studs are loaded to the loading chamber to a second welding position concentric within the first chuck. The dimension of the first chuck is such as to retain the flange of the stud and the dimension of the second chuck is such as to pick-up the shank of the stud and support it as the stud is ram fed through the first chuck into welding position during which the fingers of the first chuck grip the fingers of the second chuck to aid in supporting the stud.
Abstract:
A tire stud gun having a rotary valve thereon at one end of the housing actuated by the handle for selectively actuating the piston therein to force a tire stud into a blind bore in a tire tread.
Abstract:
THERE IS PROVIDED AN ARRANGEMENT IN HAND GUNS PROVIDED WITH A STRIKER MEANS ARRANGED FOR MOVEMENT IN THE BORE OF THE GUN BETWEEN A FORWARD AND A RETRACTED POSITION AND INTENDED TO INSERT INTO TIRE TREADS SKIDPREVENTING STUDS OF THE TYPE WHICH PRESENT A STEM PORTION AND A HEAD PORTION, AND INCLUDES A MAGAZINE DIVIDED INTO A NUMBER OF MAGAZINE CHAMBERS OF WHICH ONE IS ADAPTED TO RECEIVE SKID-PREVENTING STUDS IN NO PARTICULAR ORDER OF ALIGNMENT OR ARRAY, AN OUTLET OPENING WHICH COMMUNICATES WITH ONE END OF A STUD FEED LINE VIA A STUD ALIGNING DEVICE WHICH PRESENTS A GATE OPENING LEADING TO THE OTHER END OF THE FEED LINE AND ADAPTED TO PERMIT ONLY THOSE STUDS TO PASS WHICH ARE PRESENTED TO THE GATE HEAD FIRST AND IN A POSITION IN WHICH THEIR LONG AXES FORM AN ANGLE WITH THE CENTRE AXIS OF THE GATE OPENING, AND WHEREIN THE MAGAZINE IS PROVIDED WITH AT LEAST ONE AIR NOZZLE ADAPTED TO BLOW AWAY ALL STUDS WHICH REACH THE GATE IN A POSITION DIFFERENT TO THAT IN WHICH THEY CAN PASS THROUGH SAID GATE.
