  • Patent number: 3941916
    Abstract: An electronic package assembly having a plurality of gold-plated lead pins solderably secured within a corresponding array of pre-metalized, cylindrical-shaped holes disposed in a ceramic substrate of the package. The interior surfaces defining the holes are pre-metalized with a layer of palladium-silver followed by a layer of gold.

  • Patent number: 3939298
    Abstract: The thermal resistance of a joint for fluid filled electric power cables is reduced by transversely dividing the fluid-tight enclosure of the joint into three parts, electrically insulated from each other, namely two end parts each sealed to one of the cable sheaths and to a central part of low thermal resistance. The central part preferably has a cooling jacket. If an outer enclosure for the joint is provided its central part is made of low thermal resistance.

  • Patent number: 3937870
    Abstract: A device intended to receive two or more electrical conductors of the same or dissimilar size and to provide mechanical protection and electrical insulation for the electrical connection of said conductors, including a container for receiving the joined ends of the electrical conductors, the device including having side walls, a closed end wall and an open end and a plug member adapted to seal the open end of the casing. Passages are provided in the plug end or closed end for the extension therethrough of the electrical conductors. Cooperating locking means are provided on the plug and the casing member for mechanically interlocking the plug end casing and radial flaps are disposed in the passages which are deformed by the extension therethrough of the electrical conductor to define a cone shaped collar between the passage wall and the condutor to impede the flow of potting compound out of the device.

  • Patent number: 3936026
    Abstract: A swivel base assembly for supporting a device such as a video display terminal (including a video monitor and a keyboard) and including means for rotating the device through a large angle, for example, 270.degree.. The swivel base assembly includes a tray on which the device is positioned and a circular base member having a space for containing a circularly- wound data-carrying cable, such as a coaxial cable, for use by the device on the tray. The base member also includes a pair of upstanding spaced stop members formed therein and arranged to cooperate with a depressed stop member formed in the tray to establish the aforementioned 270.degree. range of angular rotation.

  • Patent number: 3935373
    Abstract: An insert for the ends of a splice case providing a sealed passageway which may be used, subsequent to installation of the splice case, for providing an access hole for receipt of additional cables and the like. The insert includes a first resilient tube having a rigid metal sleeve positioned thereabout and an end seal at a first end thereof. A second resilient tube extends from about the first resilient tube at a second end of said tube. The insert is positioned through an end member of a splice case during fabrication of the end member. The end seal may be cut at a later time when an access passageway leading into the splice case is required.

  • Patent number: 3934336
    Abstract: An electronic package assembly comprising a substrate having a central recess in which a semiconductor chip can be mounted. A narrow inclined groove is cut into the edge of the recess and extends from the recess bottom to the location of a screen-printed ground lead on the surface of the substrate. Conductive paste is painted on the bottom of the recess for attachment of a chip and a portion of the paste is drawn up the groove by capillary action to form a tenacious bond with the screen-printed ground lead.

  • Patent number: 3935372
    Abstract: An improved circuit modification method is provided for wire-wrapped electrical back planes such that changes in the back plane circuitry may be accomplished in areas remote from a production facility where wire-wrap equipment and highly skilled technicians may not be available, such method involving the preparation of a slip-on, post-terminal-compatible printed circuit board at the production facility, delivery of the printed circuit board to the remote area, and the slip-on attachment of the printed circuit board onto the post terminals of the back plane by a repairman who may be unfamiliar with the intricacies of the back plane and its wire-wrapped interconnections, said slip-on printed circuit board being inherently provided with whatever guidance may be required by the repairman in effectuating its installation on the back plane.

  • Patent number: 3934074
    Abstract: Disclosed is an electrical circuit board structure incorporating a ceramic substrate wafer and metallic mounting means bonded to the substrate wafer for securing the structure to a housing. The metallic portion of the structure protects the ceramic wafer from mechanical stresses transmitted through the housing by providing structural integrity and dynamic isolation. Selection of such a metallic material having its coefficient of thermal expansion similar to that of the substrate material prevents the creation of thermal stresses between the ceramic and the metal portion of the structure.The disclosed method comprises rigidly securing the ceramic substrate circuit board to the metallic member in such a way that the latter may be attached to the housing without stressing the ceramic material.

  • Patent number: 3934076
    Abstract: There is disclosed herein an enclosure for a cable splice that rigidly fixes two or more spliced cables and moisture proofs the splice and exposed cable ends. A pair of mating plug members grasp the cable ends and are then partially immersed in a body of sealant contained in a vial. The plug members include a cap portion which engages the vial and keeps the plug firmly in place. The cap portion may include extended arms which engage threads provided on the vial before the plug members fully close the vial. These arms give mechanical leverage for drawing the plug members into a fully closed position in the vial.
