Abstract: A conventional feedthrough connector having a plurality of separate passages is secured in a hole in a bulkhead, followed by feeding separate wire bundles through the separate passages. Two potting dams are secured to the connector, one at each side of the bulkhead. Each potting dam has a collar encircling a projecting cylindrical stem of the connector and tightly secured thereto, and separate integral tubular segments encircling the wire bundles, respectively. The tubular segments are soft pliant material and are gathered tightly around the wire bundles. Settable sealant is injected through a conduit that opens into the collars to fill the collars and the connector passages, and thereby seal the wire bundles in the connector.

Abstract: An electrical junction box assembly for accommodating an electrical cable inserted therein. The assembly includes a junction box and a cable clamp. The junction box includes a back wall and a side wall which perimetrically extends from the back wall to define an open end opposite the back wall. The junction box further includes a cable entry opening in the side wall for permitting insertion of the cable thereinto. The back wall further includes a cable clamp mount positioned adjacent the cable entry opening. The cable clamp mount has a clamp insertion surface positioned substantially orthogonal to the cable entry opening.

The cable clamp includes a deflectable cable engagement arm spaced adjacent from the cable entry opening of the side wall of the junction box.

Abstract: A high frequency coaxial cable (1) contains a concentric internal conductor (3), a cylindrical insulating layer (7) surrounding the internal conductor (3) and made of a foamed plastic containing more than 50% by volume of air, a tubular external conductor (9) placed over the insulating layer (7), and an outer sheath (11). Cutouts (15, 15') are made in the insulating layer (7) by removing insulation material starting at the periphery (13) of the insulating layer and extending radially inward. These cutouts (15, 15') make it possible to increase the dielectric properties of the insulating layer between internal conductor (3) and external conductor (9).

Abstract: Board delamination during the singulation from a board panel and board sagging during front-end assembly are two biggest problems encountered in cellular manufacturing lines. The method (700) and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs and v-groove configurations eliminate tearing/delamination and substantially reduce sagging.

The closure includes first and second cavitied bodies, each having two lateral sides and two end sides; a hinge joining the first and second cavitied bodies along a lateral side thereof, such that the cavitied bodies are capable of pivoting around the hinge and closing around the connector and immediately adjacent portions of the cable and the at least one electrical component. A gel substantially fills each of the first and second cavitied bodies. At least one of the cavitied bodies has a flap disposed along the lateral edge thereof distal from the hinge, for directing gel flow in the lateral direction as the first and second cavitied bodies are closed. A locking mechanism for securing the cavitied bodies in a closed position is also provided.

Abstract: Products and methods relating to composite materials and their use in coiled tubing is disclosed. The composite tubing is a pressurized structure for conveying fluids downhole in a wellbore. It has a multilayered laminate that resists buckling within the wellbore and is fabricated into a hollow tube. The fibers are oriented in angular relationship to the longitudinal direction of the coiled tubing such as to provide appropriate strength and buckling characteristics to the coiled tubing. Further, the coiled tubing layered laminate may transmit signals representing data from downhole to the surface. In some embodiments, a composite disconnecting structure having a blend of fibers of different types or orientations is shown. The disconnecting structure shows a failure load range corresponding to the failure characteristics of the fiber blend, the fiber blend having a predetermined failure limit.

Abstract: An electromagnetic shielding structure is formed from a first bracket 11 in which a box plate 11a having a c-shaped cross section accommodates a radio wave-absorbing material 11b having a surface of serrate cross section that contacts a thermal blanket 2, and a second bracket 12 having a serrate form that can mesh with the serrate form of the first bracket. The thermal blanket 2 is held and secured between the first and second brackets 11, 12. The thermal blanket 2 can be firmly joined to the satellite body by securing the first bracket 11 to the satellite body with screws. Leaked signals X are attenuated by the box plate 11a and the radio wave-absorbing material 11b. Leaked signals passing through gaps between the thermal blanket 2 and the radio wave-absorbing material 11b are greatly attenuated due to the length of the passage resulting from the serrate form.

Abstract: An electrically operated device and fastener assembly for establishing an electrical and mechanical connection on the device. The fastener assembly generally includes a fastener and a washer which may be permanently flattened against the device to establish an electrical connection to a piece of coated metal. Upon removal of the fastener, the washer remains permanently flattened against the device or piece of metal and mechanically connected thereto by a build-up of coating material on projections associated with the washer. Fastener assemblies may be constructed using, for example, sheet metal screws requiring only one of the washers in the assembly or machine screws which may require two of the washers.

Abstract: An electric power busway system has multi-phase power bus bar conductors that are each housed within an individual duct. Individually housing the bus bar conductors provides short-circuit bending resistance as well as superior thermal heat dissipation characteristics because of the improved conductive heat transfer between the bus bar conductors to the individual housing, as well as convective heat transfer from the individual housing assemblies into the ambient air. Wedge-type support braces retain each housed bus bar in position and provide short circuit support.

Abstract: A tubular-shaped housing comprising a flexible, belt-shaped wall arranged around a display instrument and/or a front pane of the display instrument. The tubular shaped housing is formed by bending the flexible, belt-shaped wall around the display instrument and/or front pane. The belt-shaped wall can be used for differently shaped display instruments and/or front panes, since the flexibility of the belt-shaped wall allows it to adapt to the outer contour of the display instrument and/or of the front pane.

Abstract: This invention is directed to a semiconductor memory device including a storage element having a ferroelectric material or a capacitor dielectric material between a top (plate) electrode and a bottom (stack) electrode. In particular, the invention pertains to the design and fabrication of the stack electrode, which is described as compound because it is comprised of two or more materials which are either patterned separately (with at least one material being deposited and patterned prior to the deposition of the others), or arranged so that each of the component materials significantly contributes to the area over which the ferroelectric or capacitor dielectric is initially deposited. These compound stack electrodes may offer ease in processing, more economical use of noble metal materials, and potentially increased mechanical stability (e.g., resistance to hillocking) relative to solid, single-material electrodes of the same dimensions.

Abstract: A rubber plug is configured to be clamped to a wire without damaging the rubber plug. An insulation barrel is clamped to a clamping surface of the rubber plug, thereby retaining the rubber plug against withdrawal from the wire. An interposing ring is interposed between the insulation barrel and the rubber plug when the insulation barrel is clamped so that side edges of the insulation barrel will not bite into and damage the rubber plug.
