Abstract: An improved locking assembly is disclosed for securing the connection between a push-on fitting having a flared end which is fitted into a cage and surrounded by a garter-type coil spring housed within the cage. The locking assembly includes a generally cylindrical coupling having a knurled outer surface and a single radial slit therein. The coupling includes at least two hinges integrally formed in the outer circumference thereof wherein at least three independent bearing surfaces are formed when the coupling encircles the connection. A multi-step circumferential recess within the coupling is utilized to accommodate variations in the external dimensions of the cage and a circular clamp or single screw are utilized to urge the single radial slit into a mated relationship such that relative axial movement of the cage and push-on fitting is restricted by radial pressure exerted by the coupling.

Abstract: A diesel engine fuel system of the type which includes a fuel heater upstream of a filter in the fuel feed line from the tank to the engine injector and wherein a diverter line is connected at one end in the engine-to-tank return line and at its other end to the feed line downstream of the filter. A valve controls flow in the diverter line and is adapted to permit flow therein while substantially stopping return flow to the tank only when the heater is operating. The result is a dramatic improvement in heater efficacy.

Abstract: A fuel injection pump for internal combustion engines is provided with an engine speed responsive governor having a governor arm suspension system that includes a spherical pivot fulcrum and a complimentary concave pivot surface on the governor arm to permit multi-directional articulation of the arm thereby preventing the slidable governor sleeve from binding on the drive shaft of the pump driven by the engine.

Abstract: An autocycling control circuit unit is provided for controlling heating and/or airconditioning systems to provide controlled comfort and fuel savings. The unit contains a night thermostat which is continually coupled to the system for maintaining a minimum temperature level. A programmable timer enables and disables a day thermostat during settable, predetermined time intervals. The timer includes a feedback circuit for varying the on-off cycling of the day thermostat, after initial warm-up, in accordance with the rate at which the day thermostat calls for heat. The unit contains a backup battery and charger to insure the proper timing sequence in the event of system power outages.

Abstract: A power hand tool including a manually engageable housing, a prime mover within the housing, a tool bit engaging chuck projecting from the housing, power transmission means within the housing and between the prime mover and the chuck; said power transmission is operable to selectively drive the chuck rotatively or reciprocally. The chuck is driven rotatively by a tube driven by the transmission and coupled with the chuck for free relative axial movement and for relative circumferential drive; the chuck is driven reciprocally by an eccentric drive means connected with the transmission and coupled with the chuck for free relative rotation and for reciprocal axial drive.

Abstract: A material handling sling comprising a main elongated, flexible, securing member, fluid inflatable means integral with the main securing member and positioned intermediate the leading and terminal ends thereof. The sling may also include a secondary securing member that is attached to the main securing member at two points intermediate the ends of the inflatable means, one point being inward the end of the inflatable means nearest the leading end of the main securing member and the other point being inward the end of the inflatable means nearest the terminal end of the main securing member; the secondary securing member being adapted to provide a working length spanning the distance between the two points of attachment of the secondary securing member to the main securing member that is shorter than the length of the main securing member between said two points.
