  • Patent number: 3945702
    Abstract: The present invention relates to a twist-type electrical connector having an improved interlock. In the connector, a plug and a receptacle are rotated angularly relative to each other to bring electrical contacts into engagement and to prevent accidental separation of the plug and receptacle. Entrance slots in the receptacle receive the male blades and carry detents which engage with a rear edge of at least one of the male blades and hold the blade in its seated or rotated position. The detents also provide an indication as to when proper connections have been established and also, prevent accidental counterrotation of the contacts.

  • Patent number: 3945700
    Abstract: An electrical connector for a high voltage, high power cable for use in an environment of high pressure fluid. The connector is comprised of parts which can be assembled in place in the field with widely available tools, by unskilled operatives. The connector includes a generally cylindrical housing of rigid material, one end of which is designed to tightly enclose an armored cable and the other end of which is provided with a coupling ring for secure attachment to a feedthrough socket, a continuous outer protective sheath of rigid material thus being provided. Within the housing, a generally cylindrical contactor support body, fabricated of resiliently deformable insulating material, seats on the wall of the housing. A contactor for each of the contacts of the feedthrough socket is sealed within the contactor support body.

  • Patent number: 3944203
    Abstract: A support for a material being cut in an oxidation cutting operation comprising a stanchion and a tip connected to and projecting above the stanchion to contact and support a material being cut. In cross section the tip is characterized by angled sides which extend upwardly and inwardly from a base to an apex which contacts the underside of the material being cut. Such a configuration minimizes direct impingement of the oxidation stream of the cutter upon the tip and directs molten material flowing from the kerf away from the support.

  • Patent number: 3941365
    Abstract: A table is shown suitable for use in supporting, manipulating and positioning human bodies or cadavers during examination, diagnosis and experimentation involving the spine. A pelvic support and a thoracic support are separately slidably mounted on a frame base table. Each support is provided with positioning rods which may be placed in predrilled holes in the pelvic and thoracic regions respectively. The positioning rods are pivoted for rotation so that the cadaver's spine may be controllably and adjustably positioned to simulate forward bending motion of the spine. The thoracic support is pivoted along two axes to provide lateral bending and rotation adjustments. Sensitive plates are positioned below and to the side of the cadaver for sequential radiographic analysis of the spinal region between the positioning rods during various postures controlled by adjustment of the rods and supports. Suitable indexing and locking mechanisms are provided so that a series of sequential positions may be examined.

  • Patent number: 3940122
    Abstract: In a quick acting clamping device a pair of pressure levers are mounted in a cylindrical housing for displacement between an unclamped position and a clamped position. In the unclamped position the pressure levers extend obliquely to the cylindrical axis of the housing and in the clamped position they extend parallel to the cylindrical axis. Movement of the pressure levers between the clamped and unclamped positions is provided by mounting one end of each of the levers in a pressure piece. The pressure piece is located in a bore in a piston mounted in another bore within the cylindrical housing. The bore in which the piston is mounted extends transversely of the housing, while the bore in the piston extends in the direction of the cylindrical axis of the housing. The housing includes passageways for introducing pressurized hydraulic fluid into the opposite ends of the bore containing the piston.

  • Patent number: 3937548
    Abstract: This invention relates to a device for splicing two wires together whereby such splice can be disconnected and the device reused. More particularly the invention provides a single elongated housing of insulating material and a one piece contact strip encased therein. The strip contains a spring member and apertured frames which receive the wire conductors. Upon forcing depressed steps on the strip into slots in the housing the apertures are deformed into electrical and mechanical contact with the conductors. The spring member retains the force thereon until release by means of a releasing tool.

  • Patent number: 3937451
    Abstract: A holder includes a first clamp and a second clamp, the first clamp having a first extension and the second clamp having a second extension, and gripping means having an opening defined therein for receiving the first and second extensions. The opening within the gripping means is of variable size so as to permit rotation of the first and second clamps when the opening is not constricted and to prevent rotation of either the first or second clamps when the opening is constricted, means also being provided to vary the size of the opening within the gripper means. Frictionless washers are interposed between the gripping means and the clamps and the extensions are spaced from each other, even when assembled, so as to facilitate the angular adjustment of the clamps and the workpieces held thereby, the stable support of the device nevertheless being maintained due to the interaction between the gripping means and the clamp extensions.

  • Patent number: 3936124
    Abstract: A waterproof connector includes a plug body with conductive blades connected internally to wires extending from an opposite portion of the plug body and a socket body having a channel in its front face. An electrical contact supporting member is arranged to fill the channel in the insulative socket body in such a manner as to define slits between opposite walls of the channel and opposite outside walls of the member. By providing electrical contacts on the opposite outside walls of the member, the plug blades can be urged into the slits to expand the slits and thereby result in a wiping action against the blades in effecting a connection.
