Abstract: A processing station adaptable to standard cluster tools has a vertically-translatable pedestal having an upper wafer-support surface including a heater plate adapted to be plugged into a unique feedthrough in the pedestal. At a lower position for the pedestal wafers may be transferred to and from the processing station, and at an upper position for the pedestal the pedestal forms an annular pumping passage with a lower circular opening in a processing chamber. A removable, replaceable ring at the lower opening of the processing chamber allows process pumping speed to be tailored for different processes by replacing the ring. In some embodiments the pedestal also has a surrounding shroud defining an annular pumping passage around the pedestal. A unique two-zone heater plate is adapted to the top of the pedestal, and connects to a unique feedthrough allowing heater plates to be quickly and simply replaced.

Abstract: The wire splice enclosure of the preferred embodiment provides a two-piece sealable cylindrical enclosure having a tension plate at each end formed parallel to the axis of the enclosure. Each tension plate is formed with a serpentine concave track of a size adapted to snugly receive a wire for splicing, with a hole adjacent the track inner end sized to allow the wire to snugly pass through into a chamber area. A pair of hooks within the chamber area provides support for the wire ends after splicing. The two pieces of the chamber are adapted to seal together with a quarter turn locking motion.

Abstract: An electrical cable has ground wires for grounding or shielding the interior of the cable. Segments of the wires project from the cable and are uninsulated. A clamp for fixing the cable and connecting the ground wires to ground includes a plastic insulating sleeve which is slipped over the cable. The sleeve has an axial extension at one end and clamping fingers at the other end. The extension is provided with a resilient, generally annular circumferential projection and the sleeve is placed on the cable with the extension adjacent the uninsulated wire segments. The latter are bent onto the extension so as to overlie the projection. The extension and its overlying wire segments are inserted in an externally threaded, electrically conductive clamping collar. The internal diameter of that part of the clamping collar which surrounds the projection and its overlying wire segments is smaller than the outer diameter of the projection and its overlying wire segments.

Abstract: A system of tubes and connector blocks to contain electrical, telephone and television cables. The tubes and the blocks are divided by walls which create separated cavities to contain the cables.

Abstract: An electrical connector having a wire-holding plug for holding a plurality of insulated wires with their bare ends protruding inwardly or rearwardly, a conducting coupler made of electrical conductive material squeezably enclosing the bare wire ends protruding from the plug, and a protective cap embedded with the conductive coupler and engageable with the plug, so that upon an insertion of the wire-holding plug containing the wires to be connected into the protective cap, the bare wire ends protruding from the plug will be squeezably surrounded by the conductive coupler within the protective cap for a convenient electrical connector.

Abstract: Splices in multi-wire cables are orderly when wires of the same length, each affixed to a pluggable connector, are joined and the connectors are rotated 180 degrees to maintain the wire pairs orderly and are bundled.

Abstract: A gas measurement probe has a casing (11) equipped with a closure shell (17) on its end away from the gas to be measured. At the other end of the casing, within its longitudinal bore, a sensor element (24) is held fast and tight in the casing. A rod-shaped part carrying a heater element fits within the sensor element and extends out of it at its end away from the gas to be measured to an extremity near which contact areas are provided on its periphery. On these contact areas, resilient connection wires lie under mechanical bias. These wires, between the loops bearing against the contact surface and their ends are bent in Z or sinuous shape so as to secure them against pulling, twisting and shaking forces. These connection elements and also another conductor running in the probe cooperate with an indexing feature of the rod-shaped element, such as a suitable groove to secure the rod-shaped component against twisting.

Abstract: A splice for splicing together the steel armor wires (3, 3') of two armored electric cable ends (1, 1') after the remainder of the cable has been spliced, and in which the end of each armor wire of one of the cable ends is joined to the end of a corresponding armor wire of the other cable end by means of a sleeve (4). Each sleeve comprises a right-and-left screw link into which correspondingly right hand and left hand threaded armor wires ends are screwed. The cable may be a submarine cable for transporting electrical power.

Abstract: An electrical connector for insulating a connection between at least two wires. The connector includes a cup shaped casing and an inner core, each having a closed end and an open end. The inner core is received within the casing defining a fully enclosed sealed cavity therein in which an insulating compound is received. The casing includes an end wall which has a plurality of recesses extending inwardly of a surface thereof terminating in thin covering membrane. A piercing member is provided for forming apertures in each of the membranes for receipt of a wire therethrough, said apertures each having a diameter slightly less than an associated wire extending therethrough providing a snug fit therearound, thereby sealing the connector cavity.

Abstract: A connector for in-line electrical wires of the same or differing gauges in which an insulating casing envelopes a continuous, wire thread which tapers from each end of the casing towards the middle of the casing and the direction of the thread is right-handed from one end of the casing to the center of the casing and left-handed from the remaining end of the casing towards the center of the casing thus providing an easily applied, low cost connector and one which has minimum insertion resistance and maximum reliability.

Abstract: To connect two bus bars to two sets of cables which are bunched to produce a low stray field, a connecting piece is provided, in which parallel, electrically conducting, plates are provided with angled-off connecting straps and connecting lugs, the connecting straps being connected to the bus bars and the connecting lugs being connected to the cable ends by means of cable terminals.

Abstract: An electrical connector and cable assembly comprising a predetermined length of cable and a pair of opposed flexible connector sections at each end thereof adapted to be separably engaged respectively with corresponding flexible connector sections on other connector cable assemblies to form an electrical cable of required size. Each opposed flexible connector section includes electric contact members connected to a live conductor or a plurality of live conductors in its associated cable with the contact members being adapted to engage complementary contact members in a connector section associated with another cable to form a connector assembly therebetween when the sections are matingly engaged thereby joining the live conductors together.

Abstract: A recoverable tubular article comprising an elastomeric sleeve held in a radially expanded or extended condition and capable of recovering to its pre-expanded condition of smaller diameter upon the removal of an outer restraint, an outer restraint, essentially tubular in configuration, bonded to said elastomeric sleeve, said bond between the sleeve and the restraint being sufficiently strong to retain the elastomeric sleeve in its expanded condition under ordinary conditions of storage and susceptible to attack by solvents weakening the bond sufficiently to allow the elastomeric sleeve to peel away from the restraint and recover to its original state.

Abstract: A connector assembly for joining gas-cooled conductors of a dynamoelectric machine. Conductor compression in two mutually perpendicular directions is provided by a pair of plate members which are slideably engaged with a pair of wedge members. A compressive force applied to the plate members is transmitted directly to overlapping conductor end portions in a first direction, and a component of the compressive force is also transmitted to the conductors in a direction normal to the first direction by means of an inclined surface engaging arrangement between the wedge and plate member. The positive, controllable biaxial compression feature provides high mechanical strength and good electrical conductivity. Bolts for securing the plate and wedge members together are inserted from only one side of the connector, thereby providing easy assembly and clearance for induction soldering and ultrasonic inspection.

Abstract: Method for splicing optical fiber cables which applies to those cables having an axial core and fibers disposed around the core, parallel to the cable axis or having a slight slant with respect thereto. At the places where splicing will have to be made, when the cable is laid down, the jacket of the cable is removed the fibers are glued on the core and two half-shells are disposed round the glued fibers and encase them. The half-shells are bonded to the core and fibers by gluing under pressure. When the glue has set, the half-shells together with the fibers and cable core are sawn perpendicularly to the cable axis which gives two half-shell segments. These segments have registering bores and splicing is achieved by inserting calibrated columns or pins into these bores.
