  • Patent number: 4797989
    Abstract: Combination machine tool apparatus and pallet changing system includes a single changer for changing both work pieces at a work piece machining station on the machine tool and tools at a tool storage station on the machine tool. The work piece machining station and tool storage station are offset approximately 45.degree. from each other as measured from the rotational axis of the pallet changer, which is provided with additional retractable rotational stops for locating the pallet changer at these additional 45.degree. indexing positions. Also, the tool storage station is located forwardly of the work piece machining station, thus allowing the pallet changer to be positioned closer to the front of the machine tool in the region of the work piece machining station without interfering with the indexing movement of the pallet changer between stations.

  • Patent number: 4795361
    Abstract: There is disclosed a clamping device which comprises a U-shaped spring secured to a spring retainer in a pivotable manner. The spring retainer is a sub-assembly which consists of two plates forming a slot when sandwiched together to accommodate the spring. The two plates associated with the retainer assembly accommodate a rotatable bolt or screw which screw is directed into a compression stop assembly. A bracket is mounted to the appropriate waveguide flange. This bracket contains an aperture to accommodate a projecting end of the spring. The mating waveguide flanges are clamped in place by adjusting the captive screw which serves to deflect the U-spring completing the clamping action. The unit, as described in the specification, contains two U-shaped springs both of which are coupled to a central spring retaining unit and can operate to connect or disconnect two separate waveguide sections.

  • Patent number: 4789358
    Abstract: The housing of the cable plug is exclusively formed of a one-piece metal part bent U-shaped which presses against the unit equipped with the contact spring elements under spring tension. In order for a shielding elimination to ensue on a short, direct path to a grounded potential carrier, the legs of the metal part nearly surround the unit or they even extend beyond it. In such a case, they are executed as resilient tongues with which an electrical connection to the grounded potential carrier directly ensues. Catch elements are provided for an interlocking connection of the metal part to the unit containing the spring clips or the blade strips. The web surface of the metal part proceeds at a slant relative to the bottom edges of its legs. In order to enable an oblique exit of the cable both toward the top and bottom, as well as toward the right and left, the said unit can also be engaged side-inverted without loss of positioning.

  • Patent number: 4787860
    Abstract: A plug and receptacle combination having a compact configuration includes a plug having a slot for receiving a raised key-like projection on the receptacle to effect a polarization function and a flush-mount latch co-aligned with the slot to resiliently engage an opening in the projection to releasably latch the plug into engagement with the receptacle. The receptacle is designed to be telescopically received within the end of the plug to provide a high degree of shielding integrity. The plug is assembled from upper and lower half-shells that retain a connection block containing contacts of a first type, and the receptacle is defined by inter-engaging inner and outer shells which retain a connection block containing contacts of a second type for inter-engaging the contacts of the first type. A resilient spring is provided on the receptacle on the side opposite the raised key-like projection to assist in maintaining the plug and receptacle in mechanical and electrical engagement with one another.

  • Patent number: 4786063
    Abstract: A bone vise for holding a bone or bone fragment immobile during surgery to enable a surgeon to perform desired sculpting or other operations thereon. The vise includes a planar base member with an integral threaded post upstanding from its central portion and a platform threadedly received on the post. A plurality of elongated gripper members are pivotally mounted intermediate their ends on the platform about axes which are tangent to a circle whose center lies within a bone receiving and engaging region. Each gripper member has a toothed surface at one end adjacent the bone receiving and engaging region and a cam surface at the opposite end weight biased into engagement with the base member. Rotation of the platform in one direction causes movement thereof away from the base member and enlargement of the bone receiving and holding region for insertion or removal of the bone.

  • Patent number: 4762497
    Abstract: A wrist strap can be connected through the fabric of a cleanroom garment by means of an inexpensive, removable connector comprising two molded plastic parts that can be interconnected to entrap the fabric. Protruding from a reservoir in the first of the two plastic parts is an open tube of open-cell foam which is filled with an electrically conductive gel. The foam tube protrudes from the reservoir and, when the two plastic parts are interconnected, the foam tube is compressed and transmits a squeezing force to the conductive gel, thus forcing a portion of the conductive gel through the exposed open end of the foam tube into the entrapped fabric and against an electrode in the second of the two plastic parts. This completes an electrical connection between that electrode and an electrode in the first plastic part at the base of the reservoir. The conductive gel may also be carried in a collapsible cup which is biased to force the conductive gel through the fabric to complete the electrical connection.
