Abstract: An improved viewing window construction for an electrical disconnect switch 10. The improved construction of the viewing window 70 permits easier installation of the viewing window 70 while at the same time reducing the complexity of the switch cover manufacturing process, eliminating the need for a window retainer 46 and increasing the resistance to the ingress of water when subjected to a stream of water under pressure.

Abstract: An electrical ceiling fan is supported from a two piece surface mounted outlet box. The outlet box back plate has two threaded fasteners that hold threaded posts, and that extended downwardly through holes in the outlet box cover. The fan has an adaptor plate that is also supported on these fasteners. The surface mounted outlet box has knock outs to facilitate assembly with surface mounted raceway.

Abstract: An electrical device mounting assembly includes a box having a top wall and a side wall extending downwardly therefrom for defining a junction box cavity therein. A fixture support is disposed in the cavity adjacent to the side wall. The fixture support includes a bottom plate extending away from the side wall, and a threaded extension disposed on the bottom plate. The fixture support may include a pair of spaced apart fixture supports. Each of the spaced apart fixture supports may be sized for supporting a ceiling fan or a light fixture. An adhesive, such as a piece of double-sided tape, may be provided on the top wall of the junction box. The adhesive assists in the installation of the junction box by adhering the junction box to a support surface for a sufficiently long period of time so that the user may have both hands free for holding fasteners and attaching the fasteners to the support and, thus, supporting the junction box.

Abstract: An optic module contains a flexible circuit board forming a cable which connects between an optical sub-assembly and a rigid interconnect structure within the optic module. One end of the cable includes lands proximate to through holes for soldered connection to pins which extend from the optical sub-assemblies. At the other end of the cable leads extend across interconnection pads on the surface of the rigid interconnect structure for soldered connection. The top surface of the interconnect pads is 10/90 (Sn/Pb) solder to provide a high temperature soldered joint. Solder flux can not be used because cleaning solvents would contaminate the interconnect structure. An atmosphere of formic acid mixed with nitrogen surrounds the lead and pad and a fluxless solder joint is formed.

Abstract: An electrical fitting support device includes a housing having a cylindrical tubular wall with a first open end and a base end opposite to the first end. A base is provided at the base end of the housing, and is constituted by two base walls extending at right angles to each other from a central longitudinal plane of the housing and being adapted to fit over a protruding corner edge of two adjoining building walls. An inlet formation is joined to the base and includes a hole for receiving an electrical conductor. A number of protrusions extend from the housing at its first end and have threaded holes for receiving screws for fitting a lid over the open end. At least two spaced apart lugs are provided extending outwardly from the housing and each of the lugs has an aperture for receiving a fastening element for attachment of the housing to a protruding corner edge of two adjoining building walls.

Abstract: A die cast housing having an open side receives a circuit which seats on a housing ledge near the open side. An accelerometer and other components carried by the board are enclosed by the housing and board. The outer side of the circuit board is covered with an adhesive sealant compound which secures and seals the circuit board to the housing without fasteners for efficient structural transmissibility, and also structurally dampens the circuit board. A sheet metal cover over the open side inhibits electromagnetic interference. Lateral ports on the housing are aligned with connectors on the circuit board and permit coupling to the circuit board by mating connectors which seal the ports. The connectors have an interference fit with webs on the housing to permit thrust testing before the adhesive sealant is cured.

Abstract: An appliance chassis (1) contains attachment elements (52) for supporting, holding and affixing electrical and/or mechanical components (55), and, in the vicinity of certain attachment elements, has one attaching device (57) for inserting and affixing repair elements (56) assigned to the attachment elements, in the event of damage to the attachment elements. When inserted into the attaching device, the repair elements replace parts (14.1) of the holding device (14), which were lost because of damage to the attachment element.

Abstract: The invention provides the suspension device for suspending a cable sleeve or fitting on a support cable. The suspension device includes a strip-shaped securing part which has one end fashioned as a hook and the other end fashioned as a mounting lug for securing to end members of the cable sleeve. Preferably, the securing part is provided with an arrangement to prevent accidental disengagement of the hook from the support cable.

Abstract: Connectors are provided which afford a substantial material match between two dissimilar metals, such as between an electronics package and the connector as well as between connector components to form an electronics assembly. In this manner, the thermal expansion properties of the electronics assembly components to be interfaced are also substantially matched, thereby allowing maintenance of a hermetic feedthru formed therebetween for a sustained period of operation. Additionally, the substantially matched component materials permit the use of simple and cost effective interfacing procedures in assembly construction.

Abstract: A switch operator, such as a manual push button, mounts a latch onto which are mounted up to four cartridges. A pair of laterally opposed arms of the latch receive each cartridge between them, and lock the cartridge to the latch. Each cartridge has four lips, two for each arm, which engage a pair of spaced apart locking surfaces on each arm. Each arm fits between the two lips it engages, and each cartridge has a pair of feet which fit into a pair of pockets in the latch. A contact cartridge has a follower, and the follower and feet are both positioned to one side of the cartridge, and the feet cooperate with the pockets to insure proper orientation of the cartridge in its position on the latch.

Abstract: First and second spaced members are hermetically sealed by a partially amorphous and partially crystalline insulating material. The insulating material is non-hygroscopic and is able to withstand forces of about 26,000 psi at about 700.degree. F. It may provide resistances of at least 10,000 megohms even when subjected to 500 volts AC or DC and to steam at about 212.degree. F. for three (3) days. A second insulating layer may be fused to the first insulating layer with essentially the same properties and composition as the first layer. However, the second layer may be more crystalline than the first layer to provide a mechanical and chemical barrier. The insulating materials may be formed from the oxides of lead, zinc, aluminum, silicon, cerium, lanthanum, cobalt, sodium, zirconium, bismuth and molybdenum. The oxides of lead, silicon, bismuth and sodium may be glass formers. The oxides of cerium, lanthanum and zirconium may form crystals. A mixture of the oxides may be heated to at least 2000.degree. F.
