Abstract: An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and metal contacts in the passages. The contacts have resilient upper and lower contact arms that deflect into upper and lower recesses of the plate when sandwiched between contact pads of overlying and underlying circuit members. The recesses are sized to accommodate solder connections between contact arms and contact pads.

Abstract: A two flail rotary flail feeding device includes a head having an annular line storage cavity, a central post and an annular line feeding passage extending from the cavity to the end of the post. Two flail lines are wound in the cavity, extend through the passage and are wound in a coil around the post. The ends of the flail lines extend outwardly from the post to form flails. Adjacent flail lines wound around the post are connected to each other and move together during lengthening of the flails.

Abstract: A carburetor for supplying fuel to an engine includes a body defining a venturi and first and second fuel lines fuel lines which discharge fuel into the venturi from a fuel reservoir. The opening of the first fuel line into the venturi is near the wall to flow fuel into the air flow adjacent the body wall. The opening of the second fuel line into the venturi is away from the wall to flow fuel into the air flow through the interior portion of the venturi.

Abstract: A pump assembly flows pressurized engine oil to HEUI fuel injectors in a diesel engine. The assembly includes an inlet throttle valve which controls the volume of oil flowed to the pump dependent upon the difference between the pump outlet pressure and a desired outlet pressure determined by an electronic control module for the diesel engine.

Abstract: A pump assembly flows pressurized engine oil to HEUI fuel injectors in a diesel engine. The assembly includes an inlet throttle valve which controls the volume of oil flowed to the pump dependent upon the difference between the pump outlet pressure and a desired outlet pressure determined by an electronic control module for the diesel engine. When the engine is cold a valve opens to assure flow of cold oil to the pump.

Abstract: A clamp connector assembly for forming a plurality of electrical connections between two circuit members includes a bottom plate below the circuit members, two retention posts extending upwardly from the bottom plate and through holes in a top plate above the circuit members, two rotary clamp members mounted on the upper ends of the retention posts with offset arms extending outwardly from the posts to facilitate manual rotation of the clamp members and actuation of assembly closing connections between the members and the top plate to force the top plate toward the bottom plate, clamp the circuit members together and form electrical connections between the circuit members.

Abstract: A laser beam is directed onto a bonding surface of a steel tool body to form a molten melt pool. Particles of high speed steel alloy are flowed into the melt pool and melt in the melt pool. The laser beam is moved along the bonding surface to form solid lines of high speed steel laser cladding metallurgically bonded to the cutter portion at the bonding surface and to each other. The cladding is abraded to form the cutting edge of a composite cutting tool.

Abstract: A portable keyboard enables touch typing with both hands without external support. The keyboard includes a first array of keys and a second array of keys on opposite sides of the keyboard. The keyboard is held between the hands and is supported against the palm of one hand for touch typing with both hands.

Abstract: A pump assembly flows pressurized engine oil to HEUI fuel injectors in a diesel engine. The assembly includes an inlet throttle valve which controls the volume of oil flowed to the pump dependent upon the difference between the pump outlet pressure and a desired outlet pressure determined by an electronic control module for the diesel engine. The assembly also includes a crank shaft with an interior drain passage.

Abstract: A rotary device useful for trimming vegetation which automatically feeds two flail lines to establish and maintain two rotary flails.

Abstract: A controlled collapse joint includes a piezoelectric coupler that frictionally couples two bodies. The coupler includes concentric inner and outer members mounted for relative motion on cooperating bearing surfaces. The two surfaces engage each other with an interference fit that resists relative motion and frictionally couples the members. One of the surfaces is formed on a piezoelectric component that moves towards or away the other surface when a voltage difference is applied to the piezoelectric component. The coupling of the two members is adjustable by varying the applied voltage difference to increase or decrease the interference fit between the piezoelectric component and the other member.

Abstract: A bone cement mixer having a cartridge filled with bone cement powder and a monomer well for receiving monomer liquid to be flowed into the bone cement powder. The monomer liquid flows by gravity in a stream near the outer periphery of the bone cement powder. The stream penetrates the bone cement powder and forms a partial cylinder of monomer-rich powder essentially uniformly along the height of the bone cement powder. The powder and liquid are then mechanically mixed to form bone cement.

Abstract: A crimper for forming a finished crimped end on a wrapper for coins or other articles has a cylindrical opening for receiving a projecting end of the wrapper into the body. A crimping structure located in the opening includes a first slide surface for sliding the end of the wrapper in a first linear direction to a second of slide surface for sliding the end of the wrapper in a second, transverse linear direction. By sliding the end of the wrapper in the two directions, the end of the wrapper is forced to roll and form a finished crimped end.

Abstract: A connector assembly includes a housing defining an interior recess, a top plate and a bottom plate on opposite sides of the housing and a compressible elastomer pad in the recess. A pin joined to one plate extends past the other plate and receives a clamp device to reduce the distance between the plates. Two circuit members are positioned between the housing and bottom plate and are held together to establish electrical connections by actuation of the clamp device.

Abstract: A removable tile wall covering includes a number of ceramic tiles held on the wall surface with disengageable-reengageable VELCRO fasteners. The wall covering is simple and inexpensive to install, and the tiles are easily removed for cleaning or redecoration.

The keyboard is held between the hands and is supported against the palm of one hand for touch typing with both hands.

Abstract: An interposer assembly for forming electrical connections between opposed pairs of circuit members includes a plate and metal contacts for electrically connecting the circuit members. A gasket surrounds the plate and sealingly abuts the circuit members when the interposer assembly is sandwiched between the circuit members.

Abstract: A high speed lock cross talk modular jack for mating with a plug mounted on the end of a data transmission cable having four pairs of twisted conductors includes wire contacts having cantilever ends extending into a plug recess and contact pins extending below the plug body. Intermediate portions of the wire contacts extending from the cantilever ends to the pins are spread and angled outwardly and the intermediate portions of the center wire contacts cross over each other to reverse the positions of the pins for these contacts.

Abstract: Case handling magazines and robot end effector for an automated storage and retrieval system in a warehouse include comb shelves for holding individual cases of goods. The case handling magazines are transported by conventional automated pallet handling stacker cranes and transfer cars. The magazine comb shelves and robot end effector have load carrying teeth spaced apart along the length of the shelves. The magazines include storage magazines for holding cases in conventional storage bays and transfer magazines for transferring cases to and from the storage magazines. The comb shelves of the storage magazines and transfer magazines are complementary with one another and enable the teeth of the comb shelves to intermesh with each other for transferring cases from a loaded comb shelf to an empty comb shelf. The robot end effector and some magazines include movable comb shelf segments that enable the selective transfer of all or less than all the cases on the loaded comb shelf to the unloaded comb shelf.
