Abstract: The compact circuit package (11) includes an insulating housing (12) providing a circuit retaining cavity (19) substantially surrounded by a pair of spaced side walls (15, 16) each terminating at a first rim (21, 22) and a second pair of spaced side walls (17, 18) each terminating at a second rim (24, 25). Each of the side walls provides an abutment (28, 31, 34) which limits the depth of entry of a electrically insulating, heat conducting substrate (30) into the cavity (19). Outer portions (44, 45) of a first pair of side walls rims (21, 22) are removed such as by a sander (46) to form a clamping surface (48) which includes an outer surface (42) of substrate (30) and reduced end portions (49, 50) of the pair of the side wall rims (21, 22) to permit increased substantial clamping pressures to a substantially planar external heat dissipating object (51) without damaging the substrate (30) and the side walls (15, 16, 17 18).

Abstract: A shielded door assembly for a generally rectangular opening in the electrically conductive wall of a grounded building has an electrically conductive frame secured to the wall along three of the sides of the opening. A tubular frame is secured to the first frame along the three sides thereof. An electrically conductive threshold having a non-interrupted contact surface is secured to the tubular frame at the remaining side of the opening. An electrically conductive door stop is secured to a first edge of said tubular frame and extends outwardly therefrom and cooperates with the tubular frame and the first frame for defining a pocket. An electrically conductive tubular door rim is pivotally secured to said first frame and is adapted for pivoting between an open and a closed position.

Abstract: An insulated conductor such as an encapsulated electrical circuit is made by locating the circuit components in a preformed carrier with opposed flexible walls with an external, outwardly facing abutment in the shape of a conical opening through each wall. The internal volume between the walls of the carrier is then filled with a hot fluid insulating plastic which also fills the conical opening forming a bridge between the openings. The bridge is caused to cool and set first so that it contracts developing a lengthwise tension which draws the walls toward each other providing the formation of air space between the walls and remainder of the filling.

Abstract: An RF shielded housing for a signal distribution system component includes a cast metal base member which forms an interior chamber in which circuit elements of the component are contained. An access aperture is provided on one wall of the housing to facilitate installation of the circuit elements within the chamber. The access aperture is closed by a cover plate which fits over the aperture into a flange portion provided in the base member around the periphery of the aperture. A number of closely-spaced sawtooth-shaped engaging elements integrally formed in the flange portion deform the cover plate as it is press fit into position against the flange portion to form a like number of closely-spaced mechanical and electrical engagements which hold the cover securely in place and prevent RF leakage from the circuit elements within the chamber.

Abstract: A contacting device is provided for achieving conductive contact between casing parts in the form of flat walls provided for electronic equipment. The device comprises a metallic strip (2) placed in perforations (3, 4, 5) along the edges of the wall (1), so that the strip runs in a wave-like form on both sides of the wall.

Abstract: A package of the flatpack type for microelectronic circuits comprises a metal base of material having good heat conductivity on which a metal frame is mounted by means of a hard brazing alloy. The frame has the function of supporting connections by means of insulating lead-in bushings of the glass bead type. The coefficient of expansion of the frame and of the base are matched so as to ensure that the base of the package does not exhibit any defect of surface planarity after cooling.

Abstract: A device for producing a hermetically sealed chip carrier is taught. Briefly stated, a sealing or perimeter ring is formed on a substrate with an appropriate lead pattern and IC chip contained within this ring. Vias or ducts are disposed in the substrate with metal lead pedestals contained therein which provide electrical connection through the substrate and therefore between the lead pattern contained inside the sealing ring and the lead patterns on the outside of the sealing ring. This therefore allows for a continuous sealing ring such that a cap may be placed on top of the sealing ring and bonded by methods such as welding so as to form a hermetically sealed enclosure.

Abstract: The electric fencer includes two plastic components having an interfitting groove and rib, as well as integral pins on one component which are pressed into recesses in the other component. The two components are sonically welded together to form a completely sealed housing. Additionally, a grommet resists the entrance of moisture along the power cord, as well as firmly gripping the power cord. The grommet is composed of a U-shaped groove on one component and a tongue on the other component, the tongue pressing against the power cord's insulation so that some of the insulation is forced into the U-shaped groove. The top of the housing overhangs the front panel so as to shield the light coming from a small neon light so that the light can be more readily seen in direct sunlight, the side walls inclining forwardly so that their upper portions assist in the shielding action.

Abstract: A partition member of a space-divider wall system having an accessible panel compartment for mounting a plurality of junction boxes and organizing data cable terminal end connections. A displaceably mounted front wall provides user access to the compartment. A plurality of support plate members are cooperatively releasably mounted on an interior compartment wall. An electrical junction box provides connections of building service to the panel system electrical components. A plurality of communication junction boxes are adhesively attached to one of the support plate members, and data cable terminal ends connected together are releasably retained on another of the support plate members by connector clips. Cables connecting to the junction boxes and the data cables extend to the panel compartment through a raceway positioned along a bottom edge of the partition member.

Abstract: A flush type wall mounted coaxial connector assembly is provided for interconnection of coaxial cables. The assembly uses a recessed wall plate having at least one internal side which is at an obtuse angle to the surface and carrying a coaxial cable connector. As a result, the cable interconnection will be behind the wall surface and the extending coaxial cable will run substantially parallel to the wall surface and not intrude excessively into the room.

Abstract: The present invention deals with an improved hermetic enclosure impervious to moisture, suitable for single or multiple chips. The enclosure is sealable at a low temperature safe for the enclosed electronic components. In particular, the enclosure employs matching direct bond copper surfaces on the substrate and on the cover which may be sealed together with solder. The cover is of a high temperature material which may be transparent. Transparent materials such as fused quartz, or garnet, or sapphire are suitable. The enclosure is economical at both small sizes and relatively large sizes; and the transparent cover material permits for optical signalling into the package.

Abstract: A padmounted transformer having an improved terminal cover-to-tank interface, which improves tamper resistance, improves corrosion resistance, and reduces manufacturing costs. The interface is formed by two equal, opposite facing acute angles in the cover, and a single obtuse angle in the adjacent tank, with the obtuse angle being substantially equal to 180.degree. minus the value of an acute angle. Closure of the terminal cover causes a leg of the obtuse angle to enter the vertex of an acute angle, to create a tortuous path for elongated foreign objects, such as a wire, and for providing a sloping surface which causes prybars to slide out of the interface seam.

Abstract: Protective cover against radiation consisting of a first special foil, which has a metallized lateral surface (metallization layer) connectable with ground potential by a grounding cord, on a plastic carrier foil and which preferably is disposed between two layers made of a plastic protective foil, characterized in that adjacent to the first special foil, an additional, second special foil is disposed.

Abstract: The RF shielding of electronic devices with a frame and sheet metal structure to form coverings for the electrical parts characterized by the structure having planar parts provided with springs to insure contact between the metal parts. Each of the springs has a pair of tabs which are connected to a center portion by a pair of bent portions having bends in at least two directions to form humps or arcuate portions. The springs are secured to the planar part by having the ends extending through a pair of apertures with the tabs engaging one side of the planar part and the center portion contacting an abutment surface between the apertures to insure that the bent portions curve above the outer surface. The abutment in the planar part may include an aperture and the center portion may have a bent nose that extends into the aperture. In another embodiment, the center portion is bent to form a nose portion which engages a web forming the abutment.

Abstract: An initiator for a contactless switch comprises a support section (3) and an adjacent, conical-shaped control section (5), which has a sensor surface (11) and is free to move into several positions with respect to the front side of the support section. In one position, the sensor surface is turned away from the support section and in other positions it is parallel to the lateral surfaces of the support section. The control section is equipped with a prism-shaped recess in which is fitted a fastening element (4). The fastening element can be rotated about a longitudinal axis (6) that is perpendicular to the front side of the support section, and the control section can be rotated with respect to the fastening element about a central axis (7) which extends in the direction of a diagonal across the lateral face of the control section.

Abstract: A circular integrated circuit package which allows a large number of internal and external connections to be made to an integrated circuit chip by arranging the pin connections as rings of concentric circles. This arrangement provides the highest possible packing density and minimizes parasitic inductances and capacitances. The circular geometry also provides for greater predictability of parasitic effects and propagation delays due to the circular symmetry of the packaging. Insertion into a printed circuit board is facilitated by decreasing the length of each successive ring of pins as the radial distance from the center of the concentric rings increases so that one ring of pins is inserted at a time. Internally, the length of internal pins may similarly be arranged, but in reverse order, so that lead length is minimized. A variety of keyway types is provided.
