Abstract: An improvement to hook and loop fastening systems of the type comprising one portion composed of backing material having a hooked surface thereon and another portion composed of backing material having a looped surface thereon. The improvement allows for releasably fastening two components together with the hook and loop materials in shear and is characterized by a planar member having one of the components attached to the end thereof and having outer faces each having one of the portions of the fastening system thereon; and, a U-shaped shear trap channel member having the other of the components attached to the closed end of the U and having inner faces on the sides of the U each having the other of the portions of the fastening system thereon.

Abstract: A universal test fixture for electrically connecting a plurality of component pins to compute test logic without the need for specialized sockets is described. The test fixture comprises a planar dielectric substrate having a multi-conductor pattern on the top surface comprising a plurality of equal width, spaced conductor bars, and including electrical conductors for connecting the spaced conductor bars to test logic. Also provided is a resiliently deformable member or material for compensating for varying planarity between the tips of the component pins to be tested.

Abstract: A refuse container assembly for storing refuse material at a refuse transfer station is provided with a receptacle, having a refuse storage chamber and a refuse material intake and discharge opening at the upper end of the chamber, mounted on a support frame for pivotal movement about a pivot axis extending transversely of the receptacle between a lower, upright position for receiving and storing thereat refuse material discharged into the opening by refuse collection vehicles and an elevated, at least partially inverted, position for discharging refuse material from the container through the opening into a refuse transportation vehicle, the assembly including a mechanism for pivoting the receptacle between the lower and elevated position, the mechanism including arms mounted on the support frame for pivotal movement about a pivot axis extending transversely of the receptacle, first extendable and retractable actuator having one end connected to the support frame and the other end connected to the arms remote

Abstract: Polymerizable acrylic monomer adhesive systems comprising thirty to eighty percent by weight powdered aluminum filler material are disclosed. More specifically, the adhesive compositions comprise at least one polymerizable acrylate monomer system; an effective amount for initiation of a free radical initiator; and elemental (atomized) aluminum metal powder or powdered alumina.

Abstract: A microwave coupler device for connecting a first stripline conductor on one level to a second stripline conductor on another parallel level is described. The device includes a resiliently deformable electrically conductive member (preferably a metal-filled elastomer) for electrically contacting first and second stripline conductors within the device. There is provision for applying a longitudinal compressive force on the first and second stripline conductors compressing the resiliently deformable electrically conductive member between them. In certain embodiments the interconnected striplines can be rotated with respect to one another.

Abstract: The visual apparatus makes it possible to limit the instantaneous luminous intensity without reducing the field of vision and comprises a plate with an opaque surface having a transparent slot, a support (2) on which said plate is mounted, said support bearing on part of the body of said person, said plate thus being placed in front of an eye of said person and a scanning means (8) connected to said plate for scanning the opaque surface of said plate by said transparent slot. The apparatus is used more particularly as medical spectacles in the case of cataracts, or as sunglasses.

Abstract: The biquad block or cell comprises two operational amplifiers OA1, OA2, eight capacitors C1-C8 and switches comprises switches of reference o and switches of reference e controlled by a clock signal H. The biquad block has six connections P1-P6 and can be used as low-pass, band-pass or high-pass filters, as a function of the connections chosen for the input and output of the signal to be filtered. Switches 46 to 52 make it possible to select one from among several configurations for each filtering function. The different configurations are distinguished by their sensitivities to the gain of the operational amplifiers and to the capacitance ratio. Application to the filtering of signals in the video range (a few megahertz).
