Abstract: Relates to plastic material molding machines and to a unitary assembly of parts installable between the hopper and the plastic pellet material inlet opening of the molding machine for providing bodily translatable movement of the hopper to one side of the machine where the remaining contents of the hopper may be discharged into a drainage collector for possible re-use at a later time. The translatable movement of the hopper is usually performed when the hopper content is to be changed and is carried out by moving or sliding the hopper while in upright position along a track extending laterally of the machine. The track occupies the upper position of a gas-tight conduit, preferably rectangular in cross section, which serves to deliver a gaseous medium to the contents of the hopper, such as hot dry air for the purpose of removing moisture from the plastic pellets in the hopper.

Abstract: Relates to tools or fixtures for removing press fit piston pins from automobile engine pistons for repair or replacement and for installing repaired or new pins in pistons. More specifically, the invention accomplishes these operations without imposing any load on the piston, thus eliminating the possibility of deforming or otherwise damaging the softer piston. To this end, one of the supporting structures of the tool is shaped in a special way to be received within the skirt of the piston and underlay the smaller end of the connecting rod thereby to receive the driving forces applied to advance a piston pin through the bore of the connecting rod for the purpose of either removing the pin or installing the repaired pin or its replacement.

Abstract: Relates to gauging mechanism for machine tools such as high production grinding machines and the like, and more particularly to a quadrilateral arrangement of arms for guiding movement of a gauge in opposite directions along two angularly related paths of travel and at different rates of speed. A power source for accomplishing such movements of the gauge is a single prime mover which reciprocatingly drives a carriage along a fixed track. In the illustrated embodiment of the invention, the single prime mover is a rotary electric motor which operates through coupling means to drive the carriage along the track with a simple harmonic motion timed to apply the desired fast and slow rates of speed to the gauge in accordance with the positions of the gauge in its paths of travel.

Abstract: Relates to an adjustable mounting bracket for instruments such as the conventional dial and air probe indicators and the like. The base portion of the instrument supporting bracket is formed from a one-piece flat strip metal stock cold worked into channel or C-shaped formation in cross section. The free ends of the opposing side wall sections of the channel formation are similarly inclined toward one another to form a dovetailed guideway or track upon which the instrument mounting bracket is slidably movable in opposite directions. The juncture of the side sections to the bottom transverse section are thinned to form a resiliently resisting hinge enabling one or both of the side sections to be resistingly inclined toward one another to narrow the dovetailed track and thus clamp and hold the complementary dovetailed extension forming part of the underside of the instrument supporting bracket.

Abstract: Relates to a method of and apparatus for electric welding through insulation coatings, such as paint, on metallic surfaces by directing a vapor jet of paint solvent upon a selected area of a painted metal surface to first soften and then vaporblast the softened paint away from the area to expose a bare spot of the metal surface for welding. Then, before the softened paint reflows back over the bare spot as a result of the discontinuance of the vapor jet, quickly bringing a metal part into welding range of the bare spot and welding the two metal parts together. Following the welding operation, the softened paint coating reflows over the exposed welded juncture and hardens to form a protective film thereover.

Abstract: A collapsible watertight structure has a pair of essentially rigid opposite end members linked together by a flexible skin or sheet so that the structure may be repeatedly extended and collapsed. Longitudinal beams which are laterally rigid but longitudinally compressible extend between and are secured at their ends to the end members and hold the structure in distended position. Each beam is secured to one of the end members by a universal joint, such as a ball and socket, and is secured to the other end member by a joint which is slidable transversely thereof whereby the end members are placed under chordal distension urging them apart and causing the flexible skin to be distended and stressed between the end members to attain its shape. Flexible cable members embedded or otherwise secured to the flexible sheet and secured to the end members limit the distension and stress imposed by the end members on the flexible sheet.
