Abstract: Connector assemblies are provided for mounting leadless chip carriers to a printed wiring board (PWB). Each connector assembly includes an elongate rigid and electrically insulative body, and electrically conductive leads. The body has two rows of pockets, each containing a lead. Each lead has two widened contact sectors. The shape of the lead is such that with one end mounted in the PWB, the sectors are opposite one another and approximately the same distance from the PWB. Each connector assembly is mounted by soldering the body to the PWB and mounting one end of each lead to the PWB. Each pocket has a channel narrower than the sector and wider than the general lead width, to restrain its associated lead to flexing movement in one direction transverse to the body. The sectors are offset in this transverse direction from the lead end mounted to the PWB, but in different amounts, thus to enable a staggered positioning of adjacent leads.

Abstract: Apparatus is disclosed for removably mounting a printed circuit card to a chassis adapted to support an array of circuit cards. Two jackscrews are rotatably mounted to each circuit card by a bracket at each end of a row of electrical pin contacts. Mounted to the chassis at each end of a row of female electrical contacts is an anchor with a jackscrew-receiving opening. Insertion of the jackscrews into the anchors aligns the pin and the female contacts and turning of the jackscrews into the anchors then causes the pin and female contacts to electrically engage. Each jackscrew carries an internally threaded crown and a plurality of ramps between the crown and bracket. Each ramp is movable longitudinally of the jackscrew and also laterally by virtue of a bore therethrough larger in diameter than the jackscrew. The crown is movable toward and away from the bracket.

Abstract: An internal combustion engine with a nozzle for injecting fuel into the cylinder under pressure and across a heater which ignites the fuel as it enters the cylinder. A variable volume pump with a longitudinally movable control lever for varying the fuel volume provides fuel to the injector nozzle. A gear drive connects the pump with the engine crankshaft. The gear drive is operable in response to engine speed to change the phase relationship between the crankshaft and pump operator thereby controlling the timing of the injection of fuel into the cylinder. In one embodiment a pair of movable racks operate to control a plurality of levers to control a plurality of pumps.
