Abstract: A cable harness assembly fixture having a crimping station and an elongate base plate movable with respect to the crimping station. A pair of spaced, parallel, locator support rails on the base plate are movable transversely of the base plate to vary the spacing between them and may be retained at selected spacings. A plurality of connector locators are supported on each of the locator support rails, are slidable along the rails and are securable to the rails. The connector locators are formed such that with the support rails set at a predetermined spacing two connector locators positioned in opposition, one on each of the supports reels, will engage and position the body of the cable connector on the base plate and will align the cable with the connector body.

Abstract: A two-reel tape cartridge in which an elastic belt extends around guide rollers adjacent the reels and a driving roller between the reels and contacts the tape on the reel hubs. The tape path between the reels is spaced from the drive belt and extends across a cutaway portion along one edge of the cartridge for access by a transducer. Tape wrap pins in the tape path adjacent each reel make less contact with the tape as more of the tape is transferred from the adjacent reel serving to make the tape tension at the transducer quite uniform as the tape is transferred from one reel to the other.

Abstract: An electrical wire connection in which an electrically conductive connector element in an insulating body makes electrical connection to the conductor of an insulated wire. The connector element has an open-ended hollow cylindrical wire connecting end formed with a pair of opposed V-shaped wire entrance areas leading into straight sided wire connecting slots and the wire is more deeply inserted into one slot than the other.

Abstract: A storage case for two different sizes of boxed video cassettes has a rectangular base and a complementary rectangular cover. Ribs formed on the interior of the side walls of the base define spaces for a plurality of one size of boxed video cassette between one pair of opposed side walls and spaces for a plurality of the other size between the other pair of opposed side walls. Ribs on the interior of the end wall of the base raise the lesser height cassette so that it extends the same distance above the base end wall as the cassette of greater height, whereby either cassette will fit closely under the end wall of the cover.

Abstract: Apparatus for inserting thin insulated wire into narrow slots of solderless electrical contacts and subsequently cutting the length of wire needed. The cutting tool is a prolongation of the shaft supporting a supply spool of the requisite wire.

Abstract: A fluid dispensing piston for a cylindrical dispensing tube has a recessed transverse end wall formed with at least one aperture. The aperture is normally covered by a fluid seal removably retained on the exterior surface of the end wall. The piston is placed in a cylindrical dispensing tube with the exterior of the end wall pressing against the fluid in the tube and the piston is moved axially down the tube to dispense the fluid. Further fluid may then be added to the tube and a second piston moved axially down the tube to dispense that fluid, the conformable material covering the aperture in the end wall of the first piston being forced away from the end wall to uncover the apertures as the second piston is moved down the tube to create a pathway for the fluid through the first piston.

Abstract: A thermal switch in which a contact spring is formed from a flat strip of metal into a U-shape with inward extensions from the ends of the legs of the U, the outside faces of each of the legs of the U normally resiliently contacting one of a pair of parallel electrical leads. The contact spring is normally supported to contact the electrical leads by a fusible pellet and is resiliently biased by a compression spring to move parallel to the leads to break the contact when the fusible pellet melts.

Abstract: Insulative sheath for high voltage cable splices has inner semiconductive member with inwardly directed bosses for positioning the sheath radially of the cable and splice and for contacting the connector of the splice to suppress corona discharge.

Abstract: A connector for insulated electrical wires in which a body of insulating material has a wire connection well formed into one surface and receives a slotted, flat plate, electrical contact element. A wire retention well is formed adjacent the wire connection well and is joined to the wire connection well by a passageway aligned with the slot in the contact element. The passageway is constricted to engage the insulation of a wire forced into the slot of the contact element in the wire connection well through the passageway and out of the wire retention well to electrically connect the wire to the contact element while providing strain relief for the wire in the passageway.

Abstract: A switch device utilizing independently acting biasing members to position a conductor to close a circuit between a pair of leads and maintain such closed circuit until a switch activating member such as a meltable pellet reaches a circuit opening state whereupon further independent biasing action causes the conductor member to assume a circuit open position.

Abstract: A container for two fluids to be mixed just prior to use in which a rigid, fluid-tight, primary container contains the first fluid and has a cover formed with two spaced parallel slots. An elongate, flexible, plastic bag contains the second fluid within the primary container and has its ends extending out of the slots in the cover of the primary container, and a squeegee is mounted in one of the slots to squeeze the fluid from the plastic bag as it is pulled therethrough. A strip of tape covers the projecting ends of the bag and is removably adhered to the cover therearound to seal the container and retain the ends of the plastic bag during shipment and storage to maintain the fluids separate until they are to be mixed for use.

Abstract: A bus bar connector system including a bus bar which is a conductive band coated with an electrically insulating material, and a conductive contact clip which is slotted to receive the bar and locally remove the insulation therefrom to electrically connect the clip to the bar. The clip with the bar defines a receptacle for an electrical terminal post and the clip has a resilient lever arm to contact the terminal post and thus complete the electrical circuit from the post to the bus bar.

Abstract: An electrical connector system which may be used to prototype electrical circuits utilizing standard integrated circuit packages on a perforated circuit board. A plurality of spring contact elements having oppositely directed resilient jaws are carried in an insulating housing. An insulating contact retainer, carrying a plurality of spring compression reserve wire contact elements, is placed on the opposite surface of the perforated circuit board from the connector housing, with a tail of each contact element extending through a perforation in the circuit board into one set of jaws of a spring contact element aligned with the perforation. The contact leads of an integrated circuit package are similarly inserted into the oppositely directed, spring contact element jaws. Electrical contact to the contact leads of the integrated circuit package is then made through the spring contact elements and the wire contact elements to wires connected by the wire contact elements.

Abstract: A thermal switch having a tubular metal casing within which a fusible pellet normally holds an axially slidable electrical contact disk in contact with an electrical lead. The body of the electrical lead extends through a ceramic bushing and out of the casing for electrical connection, and it is formed with at least one radially-extending relief lying within the bore of the ceramic bushing. A sealing resin within the bore of the ceramic bushing and around the lead retains the lead in the bushing both in normal use and after the fusible pellet has melted and the electrical connection is broken.

Abstract: An electrical wire cutting circuit breaker in which a wire cutting piston within a housing moves from a rest position to a wire cutting position under the impetus of a compression spring. The piston is normally retained in its rest position against the force of the compression spring by a retainer held in the path of the piston by a fusible stop. The retainer is resiliently biased out of the path of the piston so that when the fusible stop melts and flows at a predetermined elevated temperature the retainer will release the piston which is propelled by the compression spring and builds up kinetic energy sufficient to cut an electrical wire.
