Abstract: A balanced door operating mechanism comprising a floor sheave, a door sheave, an arm extending between the wheels, and a cable rotatably coupling the wheels. The floor sheave is fastened substantially adjacent a side jamb of the door frame between the threshold and the door, and is oriented with the axis of rotation thereof parallel to the axis of rotation of the door. The door sheave is fastened to the door coplanar with the floor sheave so that the axis of rotation of the door sheave is inset medially from and oriented parallel to the axis of the floor sheave. The substantially rigid arm is pivotably mounted at a proximal end on the floor sheave, and at a distal end on the door sheave, and carries at least part of the weight of the door. The cable frictionally engages peripheral grooves in the floor sheave and the door sheave, and extends between peripheral points of the sheaves which are closer to one face of the door than to the other. A coil type spring biases the door toward a normally closed position.

Abstract: A very secure entry door barricade system is obtained with a specially configured elongated bar which extends generally horizontally across the width of a door. A hasp assembly, which is very firmly anchored to the building structure, includes a pivotally movable hasp adapted to selectively engage a hook portion of the bar. At the hinge edge, the elongated bar is very securely anchored by a conventional hinge pin which passes through a vertical aperture in the bar and back into its hinge assembly. An alternative configuration for double doors employs an elongated bar on each door, the bar pair being generally in horizontal alignment with respective hook portions situated in close proximity to receive a ring over both hook portions. The ring, when in place, thereby serves to closely limit the extent to which either or both doors can be opened.

Abstract: A pallet having feet anchored to a platform by locking rings wherein each foot comprises a hollow tapered cup-like shape with a flange near the top of the foot, wherein the flange includes a plurality of slots, wherein each locking ring includes a flange of size and shape equal to the flanges of the feet, wherein each locking ring further includes a plurality of hooks which are insertable into the slots of the foot flange, and wherein the flange of each foot engages the underside of the platform while the flange of each locking ring engages the top side of the platform.

Abstract: An automatic door installation with two traffic sensors mounted on each side of the door adjacent the opposite side edges thereof, each having a reflected energy receiver and a plurality of radiant energy emitters with angularly spaced beam axes to provide broad coverage areas intersecting the traffic path of travel. The emitters of each sensor are selectively activated at different radiant energy levels and/or selectively deactivated to vary the effective coverage area as the door is swung between its closed and open positions.

Abstract: A window regulator mechanism using a wire for opening and closing an automobile window has a driving portion including a drum to which a handle shaft is mounted, two brackets, two pulleys pivotally mounted to the brackets, the wire being wound on the drum and trained around the pulleys to form a closed loop, two elastic tubes mounted between each bracket and the driving portion for guiding the wire and for always elastically connecting the brackets to the driving portion, and an auxiliary elastic member mounted between the driving portion and the portion of the wire which lies between the pulleys. The drum and the pulleys are disposed in a triangular form. The auxiliary member gives a tension to the wire to prevent the wire from disengaging from the pulleys when the mechanism is mounted to the panel.

Abstract: A prefabricated door assembly for insertion in a door opening in a wall of predetermined thickness comprises side and head jambs of a width less than the wall thickness, and the frame is completed by extender casings each comprising a molding which is butt jointed to the outer surface of an extender piece that has its opposite edge butt jointed to its complementary jamb to complete a frame assembly of the proper width to fit the door opening with the molding pieces overlying the junction between the extender pieces and the wall. These features provide significant savings in the cost of materials and also in the space required for shipping the prefabricated base frame assemblies prior to addition of the extender casings thereto.

Each of the front and rear gaskets may have a flange portion thereon for insertion in an opening in a gasket attached to a frame of the window opening in the vehicle door.

Abstract: A revolving door has a plurality of leaves mounted for rotation about a common axis. To permit collapse of the door in an emergency, the leaves are mounted, at each end, by means of mechanisms that permit such collapse. There is provided a mechanism for mounting one end of a door leaf, the mechanism having a support plate for rotation about the central axis. First and second pivot means are mounted on the support plate, and corresponding first and second pivot devices are mounted on the door leaf. The pivot means and devices, e.g. corresponding projections and recesses, are such that, the door leaf can pivot about one pair of pivot device and means, while the other pair of pivot device and means separate from one another. Once rotation has commenced about one pair of pivot device and means, they are such that they cannot then be separated, thus securing the door.

Abstract: A drive train system for rotating an axle in an external system about an axis which is perpendicular to a driven shaft. The driven shaft has a drive screw thereon and is rotatable about a fixed axis. A drive nut is located on the drive screw and is movable along the length thereof as the drive screw is rotated. A two-part, slidably interconnected crank arm has one part fixed to the axle and the other part slidably interconnected with the drive nut. A power drive is operably connected to the driven shaft through a friction drive including a driven member mounted on the shaft by means of a slip fit through a center hole and a friction plate rotating with the shaft through a center opening. An annular-ring surface between the driven member and the friction plate creates an interface which limits the frictional drive force developed thereby.
