Abstract: A holder for pads on which dummy connector mates are fixed includes a U-shaped bracket arrangement grooved to receive the pads. Once the selected pad is in position threaded fasteners are extended into the edge cutouts in the pad to fix the pad in the holder.

Abstract: A triangular, sharp projection is formed in the surface of a key handle, the projection being directed into the interior of a key ring opening formed therein. This key ring projection includes edge recesses formed proximate the base thereof thereby providing a shape forcing the segments of a collapsed helical key ring apart, the recesses then maintaining the ring segments separated for insertion or removal of additional keys. In an alternative implementation the similar key ring separation projection may be formed on articles other than keys that can thus be carried on the key ring for convenience in key removal.

Abstract: An adapter for mounting on the interior mirror assembly of a motor vehicle including two mirror segments hinged to each other and engaged at the free ends to the assembly. A cam adjacent the hinge can then be used to set the relative angular alignment between the segments.

Abstract: A sweeper assembly for use with escalators includes a frame having a pivoted end structure on which a weighted bar is fixed to press a polishing pad adjacent a bristle element against the moving surfaces of the escalator. A vacuum cleaner is then rendered operative to draw the debris thus loosened into a nozzle deployed adjacent the bristle element.

Abstract: A foldable dashboard shield for use in screening the dashboard of a motor vehicle in formed of a thin sheet, like cardboard or one of the rigid polymers, scribed with fold lines which in one manner of folding convolve the shield into a folded stack for storage and in another manner of folding form a triangular structure. The shield may be inscribed with markings and when folded in the other manner may be used as an emergency road sign.

The film path may include bristle like strips for damping film waveforms higher than the first mode.

Abstract: A shelfing system is disclosed herein for use in storing data processing devices, said shelfing system including cooling blowers in the surfaces thereof for cooling the electronic equipment stored therein. The shelfing system, furthermore, is pivotally fastened for convenient maintenance access with the pivotal motion thereof restrained by a locking mechanism. Alternatively the shelving system may include locks in the various panels thereof which support a pivoted turntable to which the monitor of the data processing system is attached. This turntable includes a resilient panel compressed within the bearing which then imposes friction in the motion thereof for fixing the monitor alignment.

Abstract: A powered fastening tool described herein is useful to align and secure structural members to each other, the structural members having misaligned securing apertures. To accomodate this misalignment two eccentric bushings are nested and swaged together to be inserted into one of the misaligned apertures to be turned therein by the powered tool until an alignment is reached. The tool holds a fastener while concurrently rotating each eccentric bushing at an independent rate until hole alignment is achieved. At this point, the tool inserts the fastener through the hole in the lower structure and is then used to rotate the fastener into threaded engagement.

Abstract: A method for producing stable, layered electrets includes the steps of placing a thin sheet of glassy polymer or copolymer of high molecular weight, such as polyethylene terephthalate, between two, somewhat larger in planform, sheets of polyvinyl chloride and/or polyvinyl acetate formulation, to form a sandwich structure which is then compressed and heated to approximately 300.degree. F. At this temperature the exterior polyvinyl chloride or copolymer sheets are polarized and displaced under pressure over the interior sheet to charge the interfaces of the exterior and interior sheets. The heat, furthermore, bonds the peripheral edges of the larger exterior sheets to each other thus forming a hermetically closed container within which the charged interfaces will reside. Alternatively, two or more sheets of electret (polymer) material may be pressed and heated against each other to a point where plastic deformation occurs but below melting.

Abstract: A drill pipe spinner is disclosed including cam surfaces which in the course of tensioning the chain close the jaws of the spinner. The same cam surfaces provide jaw opening moments on release of the chain tension to allow the separation of the spinner from the pipe. These cam surfaces are formed on either side of two tracks in which two slides are fixedly connected to idlers which engage the chain. The idlers, moreover, are mounted for rotation on a transverse bar connected to a hydraulic actuator for tensioning the chain by convolving the chain path.

Abstract: A counterbalanced, long stroke pumping system provided with a composite material lifting string is conformed for optimum separation between the frequency spectra entailed in the pump drive and the fundamental resonances of the string. This separation allows for an expanded control bandpass within which an adaptive control system may be rendered operative to adjust stroke mechanics to meet pump-off conditions or other pumping anomalies.

Abstract: An enclosure generally shaped to simulate the appearance of a flight vehicle is provided with a seat facing a video display and is supported on a parabolic dish for freedom of angular motion in the pitch and roll modes. Included in the enclosure may be a weighted control stick which, according to its angular displacement, displaces the effective center of gravity, thus moving the enclosure in the pitch and roll modes. A set of orthogonal resolvers deployed in the enclosure and pendulum articulated provide binary signals of the pitch and roll angles achieved to the video display, simulating the flight vehicle attitude while a program is cycled through a microprocessor and superposed onto the pitch and roll inputs to generate on the video screen images simulating flight.

Abstract: A portable light assembly conformed for excitation from the cigarette lighter outlet of an automobile comprises two light housings each universally pivoted from a central handle assembly. The central assembly includes opposed pivot fittings from which two laterally disposed swivel blocks are pivoted, each swivel block in turn pivotally supporting a corresponding light. In this form the alignment of each light may be individually selected to produce any desired beam pattern, the same pivotal freedom providing for a collapsed alignment where the lens portions of each light are protected from damage.
