Abstract: A metal body, for example, a cover for hermetically sealed electrochemical cells, is relatively flexible and electrically conductive. An aperture is provided within the body to receive an electrically insulating material, such as glass, which mounts a terminal or metal lead, for the cell. In the process for producing the seal, the body is positioned with the lead therein and a sealing glass is placed thereabout. The assembly is fired at a temperature high enough to achieve melting of said sealing glass and effecting a between the body, lead and glass to form a glass-to-metal seal. At least one surface of the lead is then ground to be flush with the glass and then the assembly is refired to heal cracks formed in the glass by the grinding operation.

Abstract: A process for producing multi-chip wiring arrangements which consist of a ceramic carrier with through contact holes associated with thin film wiring on one side of the carrier and with multi layer, thick layer wiring on the other side of the carrier. The holes on the one side of the carrier are metallized and galvanically strengthened while the holes on the other side of the carrier are sealed by baking therein a thick layer of paste. Thereafter the multi layer, thick layer wiring and the thin film wiring are produced in that order.

Abstract: A clamping device for securing HF fittings to coaxial cables or hollow conductors by means of a clamping sleeve surrounding the cable outer sheath or the hollow conductor sheath. The sheath is radially inwardly deformed by the clamping sleeve in such a manner that a transformation is effected which guarantees a reflection-free transition to the adjoining fitting. In the end portion of the cable or hollow conductor the outer sheath is engaged radially so that it is compressed, giving a reliable hold. The cable sheath is thus deformed in a definite manner so that at the point of entry into the fitting it has a predetermined size, said deformation gradually or abruptly decreasing towards the cable in a transformation portion. This deformation can be effected by suitable means, for example axial tensioning or by a two-part clamping sleeve with tangential tensioning.

Abstract: The apparatus includes a conveyor table having pairs of press heads mounted on its opposite sides. Strips of sheet metal stock from coils are fed through respective die sets for punching integrally extending teeth in the metal strips and the connector plate stock thus formed is fed into the respective paths of movement of upper and lower press platens. The platens are movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of joints formed by wooden frame members disposed on the conveyor between the press heads. Simultaneously with the pressing operation, the die set punches additional teeth into the strip. Upon completion of the pressing operation, a feed mechanism locates predetermined lengths of connector stock with struck teeth between the press platens for the next cut and embedment operation.

Abstract: A method of truing a newly built spoke wheel having a hub and rim, subsequent to fitting spokes to the wheel and loosely screwing nipples to the spokes at the wheel rim. The method comprises securing the rim and hub in a concentric relationship, locally depressing the rim relative to the hub to a datum radius in the region of a nipple, tightening said nipple at least partially, and further locally depressing said rim relative to said hub in the region of each of said remaining nipples until all of said nipples are tightened as desired.

Abstract: Press fit contacts having upper mating portions are stamped, formed and oriented out of sheet material for simultaneous insertion and housing in a removable connector insulator. Receiving sleeves formed in the insulator are constructed to permit the contacts to be bottom loaded into the sleeves, seated and lightly held therein. Each contact includes an intermediate press fit collar portion which engages a mating shoulder in the insulator. The insulator serves as a holding fixture and seating tool for transmitting insertion force applied to the top of the insulator to each one of the contacts for press fitting them into contact receiving apertures in a mounting substrate. The contacts held by each insulator are all simultaneously press fitted into the substrate by continuing to apply pressure to the top of the insulator until it is mounted flush upon the substrate.

Abstract: A method for producing electrical connector strips which have soldering extensions arranged within an insulating carrier where the strip is formed apart from the insulating carrier and treated with an active deoxidation agent, tinned in the region of the soldering extensions, then placed in the insulating carrier and finally free-cut in such a fashion as to preserve solderability of the extensions.

Abstract: An electrical igniting unit for cigar lighters, engine ignitor plugs, and the like comprising a wound spiral of resistance ribbon which is carried in a shallow metal cup to span the mouth thereof. The inner end of the ribbon is secured to a metal stud as by crimping and/or welding it in a slotted head thereof. The outer coil convolution is secured to the rim of the cup by forming inward the rim edge into a tight curl which is laid over on the end portion of the coil convolution. A relatively large area of the coil end is thus tightly and securely pinched under continual pressure, to establish a low-resistance effective mechanical and electrical connection between the cup and the coil.

Abstract: A connector for light-conductive fibers includes a connecting body provided with at least one receiving passage and at least two aligning passages. The connecting body is subdivided into two connecting members along a plane normal to the axes of the passages, the connecting members having contact surfaces at the subdividing plane which are adapted to abut one another when the two connecting members are assembled. The end portions of the light-conducting fibers are introduced into the receiving passages so that the end faces thereof are flush with the contact surfaces, and the connecting members are assembled in alignment with one another, using aligning elements accommodated in the aligning passages of the connecting members. The connecting body may be produced by embedding auxiliary elements corresponding in diameters to the aligning elements and the fibers, in a body of a hardenable material, and by removing the auxiliary elements from the body after the hardening of the material.

Abstract: A terminal applicator for applying terminals in the form of a continuous belt and having a crimping die and a crimping anvil movable relatively towards and away from each other is disclosed. The belt of terminals is fed along a feed path extending behind the dies to present and index the leading terminal on the belt to the dies. After crimping, the dies move relatively away from each other to free the crimped terminal. An ejector means is spaced laterally of the feed path and moves into engagement with the wire and away from the dies, while the other end of the wire is held by a wire clamp, so that the crimped terminal is broken away from, and thereby removed from, the belt. In one embodiment, the wire clamp is movably mounted for lateral movement toward and away from the dies, so that the wire end may be inserted into a closed-barrel terminal prior to the crimping operation.
