  • Patent number: 7249670
    Abstract: In a conveyor work-piece processing system, transport carriages move along a work path, each carriage carrying a plurality of work-piece articles. In the disclosed embodiment, the path is folded back upon itself forming two parallel paths, one above the other, with transport carriages moved vertically from the lower path to the upper path, so that the entrance to the track and the exit from the track are positioned in close proximity to each other. Each transport carriage has a long dimension and a relatively shorter dimension, and each carriage can be reoriented selectively so that the long dimension or the short dimension can be aligned parallel to the work path. Changing the alignment of the two dimensions relative to the direction of the path permits a work piece to remain for a longer time within a given process stage or area along the work path while achieving a system flow-rate of one carriage-in-one carriage-out.

  • Patent number: 6618876
    Abstract: A bed headboard assembly that is entirely independent of support associated with any other part of a bed structure such as the mattress, spring or bed frame, embodies a generally soft, panel-like member having length and width dimensions that are substantially greater than its thickness. A fabric container encloses the panel and has an access opening for inserting and removing the panel. The access opening can be dosed with a zipper or hook-and-loop closure device. A rigid support member is coupled to the panel member parallel to one edge, so that the panel can be suspended from the support when said support is hung on a wall next to a bed. Decorative patterns on the outer surface of the fabric container and pocket recesses in either the fabric or the panel or both, enhance the functions of the headboard for visual appeal and for the convenience of a user of the bed.

  • Patent number: 6619341
    Abstract: A pouring spout for hand-held portable fuel tank incorporates a float valve to automatically shut off fuel flow through the spout when the fuel level in a receiving reservoir reaches a given spatial relationship with the outlet end of the spout. An axially displaceable locking magnet within the spout locks the valve in the closed position. The locking magnet is released from its locking position by an unlatching magnet incorporated in a sealing cap. The unlatching magnet cancels the magnetic force that holds the magnetic valve in the closed position, thereby allowing it to move to its open position only when the closure cap is in position to seal the spout. The locking mechanism includes an axially displaceable magnet of given axial length, that is captured within a sealed container positioned in the pouring spout. The sealed container has an axial length greater than the length of the magnet.

  • Patent number: 5785011
    Abstract: A breakaway strap assembly for tethering a domestic animal such as a horse, employs two elongate straps separably attached by mating hook-and-loop surfaces. The mating hooks and loops resist longitudinal separation of the two straps. The hooks and loops are formed of resilient plastic material that permits them to unbend elastically so as to disengage from each other. Anchor clasps at one end of each strap allow the straps to be attached, respectively, to a fixed structure, such as a building and to a movable point such as the harness worn by a horse. The axial force resisting separation of the two straps can be varied from a low value to a relatively higher value by varying the longitudinal overlap of the two straps.

  • Patent number: 5733109
    Abstract: A novel single acting variable displacement vane pump (VDVP) incorporating novel vanes and undervane venting which produce selective regulated pressure-loading of the vanes against the cam surface and more positive tracking in the incoming seal arc and the outgoing or discharge seal arc of the pump rather than uniform pressure balancing of the vanes throughout the 360.degree. cam chamber. The vanes incorporated into the present pumps preferably are sectional two-piece vane assemblies comprising an upper vane section which slidably supports a lower vane section and incorporates a fluid pressurizable cavity between said vane sections which, when pressurized, forces the vane sections in opposite radial directions, and which enables the vane sections to come together and integrate when the cavity is depressurized. The vane cavity is open to the fluid pressure on one side of the vanes while the undervane area of the vane slots, below the vanes, is open to the fluid pressure one the opposite side of the vanes.

  • Patent number: 5716201
    Abstract: A variable displacement vane pump having a vaned rotor adjustably contained within a cam member for rotation between fuel inlet and fuel discharge arcs. Adjacent vanes form enclosed fuel bucket areas which are expanded and axially-supplied with fuel in the fuel inlet arc and are contracted and axially-discharge the fuel in the fuel discharge arc. Fuel circulation is improved by providing a central recess at each vane tip and/or a central groove in the cam surface to prevent trapping, stagnation and overheating of fuel at the centerpoints of the bucket areas, which overheating can result in expansion of the vane tips, scoring of the cam surface and pump failure.
