Abstract: Slide hammer apparatus including means for restraining and non-rotatively driving and pulling fence posts. A handled, hammer section mounts in concentric, sliding relation to a main body which surrounds a fence post and contains upper and lower stops. At least one stop includes an adjustable clamp means and anvil acting pin for securing a post to the main body and permitting reciprocal motion.

Abstract: An active, relatively high gain, low power consuming band pass filter circuit centered at approximately 6 KHZ and having a pass band of 100-200 HZ. In a disclosed glass breakage sensor, the filter couples sensed ambient sounds of breaking glass to associated detection, driver and annunciator means. Signals of appropriate duration and frequencies indicative of breaking glass are thereby monitorable to define and induce an alarm condition within a security system.

Abstract: A hinged spare tire carrier externally mountable to a vehicle body and rotatable on compound hinged axes between latched rear and side mounting positions. In various alternative embodiments, the assembly includes a pair of fixed and adjustable multi-axis pivot links, pivotally hinged to the body and an extension framework which separately supports a rotatable tire support framework. Latch assemblies secured to the body and frameworks restrain one to the other and the vehicle during vehicle operation. In another embodiment, a compound hinged triangular framework includes a rotatable, tire supporting cross-arm. In still another embodiment a vertically rotatable tire support arm is provided.

Abstract: A seating support for independent, multi-planar adjustable thoracic and pelvic-sacral cushions for supporting the spine and permitting support adjustment by the seated occupant. The thoracic support cushion is inflatably adjustable in a horizontal plane and vertically adjustable relative to apertured slide rails of a support framework. The pelvic-sacral support cushion vertically slide adjusts along the framework and is horizontally adjustable via a screw follower mounted scissors assembly having a laterally and tiltably rotatable cushion mounting plate. In an accessory embodiment, an adjustable clamp retainer and strap secure the support to an available rigid-backed chair.

Abstract: A padded automotive and child accessory seat cushion with arms for supporting and partially camouflaging a buckled restraint, whereby a seated child is distracted and comforted with separately surrounding padded arms. The arms extend from a cushion back, which is hingeably secured to a cushion seat and, relative to which back and arms, fasteners secure the restraint thereto. Buckles on the outer arm surfaces permit the adjustment of arm length and fasteners at the padded palms secure the arms to one another.

Abstract: A folding wheelchair frame including a compound folding mechanism having fore and aft tubular hinged wing frames pivotally coupled to the chair's side frames and to a longitudinal tubular slide-follower coordinating assembly. Scissored arms coupled between the forward hinged frame and slide-follower coordinate the folding action relative to the chair's longitudinal center axis and allows the latching thereof. Associated swing-away footrests, removable armrests and latched, folding back frames further reduce the folded profile and facilitate chair usage.

Abstract: Abrasive grinding apparatus wherein abrasive heads rotate about axes inclined at forty-five degrees to the longitudinal axis of a parts conveyor mat and in orthogonal relation to one another. Watering tracks positioned in overlying axially parallel relation to the abrasive heads and in transverse relation at the end and beneath the conveyor mat wash the exiting parts and the conveyor mat. Parts engaging pressing members comprised of a plurality of spring biased support frames each bearing a rotative, longitudinally displaced belt and having beveled sides adjacent the abrasive heads guide and maintain the parts in contact with the conveyor mat as they are transferred to and from the abrasive heads.

Abstract: An externally mounted, insect-proof screen curtain assembly for large door openings. The curtain is raised and lowered via draw pulley supported ropes, vertically threaded through rings sewn to the curtain material. Spaced apart horizontal rope containing hems and a bottom weight member maintain a flat exposed screen surface relative to slide track mounted side hems. Flexibly resilient side seal members mounted in wiping relation to the screen sides, along with a compressible horizontal bottom seal and a fixed head seal, make the assembly insect-proof.
