  • Patent number: 4894906
    Abstract: The ends of two composite superconductors (10a and 10b) having many filaments (12) are joined together to form a joint that is durable, superconducting under proper conditions, and has good shunting capacity. The filaments (12) are exposed by removal of the normal conducting matrices (14a and 14b) from the ends of the composite conductors (10a and 10b) to be joined. The superconductive filaments (12) from each of the composite conductors are inserted together into a sleeve (16) of bimetal construction. The inner surface (18) of the sleeve is made of superconducting material and is metallically bonded to the outer surface (20) of the sleeve which is made of normal conducting material. The bimetal sleeve (16) abuts the matrices (14a and 14b) of the composite conductors (10a and 10b) on one end, and the filaments (12) extend beyond the opposing end of the bimetal sleeve (16). The bimetal sleeve (16) is crimped to form a cold weld joint, and then severed in the region of the crimp to form another cold weld joint.

  • Patent number: 4856185
    Abstract: For fastening electronic components to substrates, a connecting layer having good adhesion and good electrical and thermal conductivity is manufactured by sintering from a metal powder layer. A paste formed of metal powder, such as a silver powder, and of a solvent, is processed into a solvent-free presintered film in a separate process. This film is punched in accordance with a cross-section of the component and is provided for fastening the component. In manufacturing the film, a specific solvent is employed, together with heating up rates of 5.degree. to 30.degree. C./Min and holding times of 0.5 to 5 minutes at a maximum temperature of 300.degree. C. The fastening is carried out at temperature of at least 150.degree. C. and at a minimum mechanical pressure of 30 N/cm.sup.2. The use of a film speeds up the method and enables of sintering at low temperatures and, at the same time, at low mechanical pressure.

  • Patent number: 4854037
    Abstract: A pair of displacement levers maximize the holding strength of hook and loop attachment devices. A first piece of hook or loop material is firmly attached to a platform. The material attached to the platform is complementary to and mateable with material attached to the other surface. The displacement levers are rotatable and connected to both ends of the platform. Rotation of the levers causes the leg sections thereof to displace the platform. This causes the hook and loop materials to move in opposite directions thereby firmly setting the hooks and loops with respect to each other and placing them in tension. Wire holding posts attached to the platform on the side opposite from the hook or loop material are used to form bends or corners in wire harnesses on wire harness forming boards. Holding devices such as clothes hooks, clamps, rings, etc. could also be attached to the platform so that other items can be supported by the device.

  • Patent number: 4852249
    Abstract: A process and device for the length trimming of cables from a cable supply for the processing of cable ends. The cable front end is inserted by a cable feed (20, 22) in a guide channel whose rear section is located in a swivel part (28). As the cable front end impinges on a stop (102) on the swivel part (28), said swivel part swings beyond a dead center which is defined by a spring (40) which is attached eccentrically, whereafter the swivel part (8) is swung around by the spring (40) essentially 180.degree. so that the cable front end bearing on the stop (102) points opposite to the feed direction. The cable loop formed is then enlarged to the desired length by continued cable feeding, whereafter the cable rear end is severed by a knife (82). By lowering the cable, the cable ends are transferred, accurately positioned, to holders (56) by means of which they can be transported to the processing stations.
