  • Patent number: 4829732
    Abstract: An improved anchor socket and jig assembly for holding implements in concrete is provided which facilitates assembly of the socket element on the base member of the jig assembly and which affords substantially expanded adaptability of the jig for varied size implements and avoids the need for bolts or other extraneous means to secure the socket member to the rail member.The improved jig assembly comprises a longitudinal base member preferably of substantially rigid plastic composition which is provided with locator openings which fit one of the feet of the socket member and, cooperating therewith, a mating turn slot. Both the openings and the turn slots are formed to accommodate the feet of the socket member. The assembly of the socket in the base member in a secure position is readily effected by positioning the socket member between the rails of the base member and locking the two by a manual quarter turn rotation of the socket member in the base member.

  • Patent number: 4763457
    Abstract: A barrier is constructed from a plurality of cell-like elements interconnected to form a rigid barrier under normal circumstances. The linkages between cells provides a friction-brake force which is exceeded upon application of a traumatic force such as a bomb blast. The linkages includes slots in each cell connecting adjacent cells with prestressed nuts and bolts to permit sliding relative movement between adjacent cells after a predetermined threshold force has been exceeded. A transverse reinforcing rod, having a series of plates along its length, passes through adjacent cells. The plates act as a viscous damper as they move through a filler material within the cells while the rod adds strength. The cells may be coated with a dry lubricant to control the static coefficient of friction. The ability of the cells to move protects the barrier from structural failure by dissipating the blast forces through the frictional work required to displace the cells.

  • Patent number: 4753465
    Abstract: A locking mechanism for securing together two separable pieces, such as two components of a spacecraft during launch. An elongated rod of heat contractible material provides a single active member which changes from a locking length to a contracted length upon application of sufficient heat to raise the temperature of the rod from below to above its transition temperature. Mounting and housing structures are provided for mounting and heating this transducer rod and an apertured member or recessed stop is provided for engaging a projecting portion thereof. Heating may be provided by redundant, electrically actuated heating coils surrounding a major portion of the rod length. At least a major portion of the transducer rod may be made of 55-Nitinol.

  • Patent number: 4737059
    Abstract: There is disclosed an easily releaseable, internally threaded fastener having at least one axial slot which extends substantially through the wall of the fastener. The external wall of the fastener is non-cylindrical, e.g. hexagonal, or three-lobed, to permit the application of a fastening torque to the fastener. The fastener is surrounded by a retainer sleeve having a mating, internal wall portion which provides hoop strength to the fastener. The retainer also has an annular recess in its internal wall whereby the retainer can be slid axially, or rotated, to release the fastener. The fastener assembly includes a metal spacer seated in each axial slot of the fastener to permit the even transmission of the fastener application torque.
