Abstract: The Power Bar with Remote Control allows a user to control from a distance the power of each outlet contained in the attached Power Bar. A master switch also allows the power to all outlets to be turned on or off in unison. Therefore, a user can selectively turn on or off electrical devices attached to the Power Bar. For example, while sitting at a desk a person could use the Remote Control to turn on their personal computer, monitor, speakers, external modem, printer and desk lamp. Also, by integrating the Power Bar with a USB (or Firewire) hub, only a single composite cable, with either integrated AC power/USB plugs or separate AC power and USB plugs at each end is required to supply both power and data to a PC or peripheral device. Also, by integrating an under-the-monitor type power box with a USB (or Firewire) hub, only a single composite cable, with either integrated AC power/USB plugs or separate AC power and USB plugs at each end is required to supply both power and data to a PC or peripheral device.

Abstract: An apparatus and method is disclosed for lubricating the spaced apart beads of a pneumatic tire prior to mounting of the tire on a wheel. A conveyor is provided for moving the tires having different outside diameters, axial widths, and central opening diameters fed in random succession along a fixed path through a lubrication station. An interceptor is positioned in proximity to the station and is moveable between a first position where tires delivered to the station by the conveyor move freely through the station, and a second position where tires delivered to the station by the conveyor engage the interceptor to stop the tires on the conveyor at the station. The interceptor stops successive tires of varying sizes to perform a lubrication operation on the tires of varying sizes when intermixed on the conveyor in random order. The interceptor is selectively moveable between the first and second position. At least one longitudinally extending, lubricating member is provided having a first axis.

Abstract: A flap-type pressure relief valve for venting of pressure out of, for example, an automobile passenger compartment has a flap assembly manufactured by a co-molding operation and inserted into a valve housing to block the flow of air therethrough. The valve flap assembly includes a flap carrier frame formed from a relatively rigid plastic in the first shot of a two-shot co-molding process, and at least one flap formed from a relatively flexible plastic in the second shot. The co-molding joins the flap to a first perimeter wall of the frame along an edge of the flap, and the flap is sufficiently flexible to bend about a line adjacent the edge. In a two flap version, a second flap co-molded into connection with a second perimeter wall of the frame. The resulting flap assembly can be easily connected with the separately-molded valve housing by securing the frame to the housing such that the flaps are positioned over valve seat within the housing.

Abstract: A tolerance-accommodating, flexible mounting pad formed integrally in the base point mounting portion of a bussed electrical center cover. The base point of the bussed electrical center is adapted to be secured directly to a vehicle mounting surface, the location of which may vary due to dimensional variations within an expected tolerance range. The cover is typically secured by one or two fixed mounting points at an upper portion thereof to mounting points in the vehicle, and the tolerance-accommodating mounting pad is then used to secure the base point of the cover directly to the final vehicle mounting surface. If a gap exists between the base point and the vehicle mounting surface due to variations within the expected tolerance of the vehicle mounting surface, a fastener inserted through the mounting pad and engaging the mounting surface is operable to flex the normally recessed mounting pad outwardly into direct, tensioned contact with the vehicle mounting surface.

Abstract: A method and apparatus is provided for applying a plaster-like coating material to the decorative exposed surface of a preform workpiece. The apparatus comprises; means for mechanically advancing a workpiece along the apparatus along a straight horizontal axis over a non-continuous surface; means for engaging the bottom portion of a workpiece to constrain lateral and vertical movement as the workpiece passes along the apparatus; and means for applying a desired thickness of plaster-like coating material to a decorative surface of an advancing workpiece. Both the method and apparatus provide on a consistent basis, a smooth coating with a controlled thickness tightly bonded to the entire exposed decorative surface of a workpiece. The method and apparatus provide a simple, efficient, cost effective and reliable means for applying a plaster-like coating to the exposed decorative surface of a workpiece for use on a commercial scale in the construction industry.

Abstract: A refueling fuel level responsive control valve with a two-stage closing operation providing an initial soft shutoff cue to the filler nozzle operator, and a subsequent final shutoff after a limited amount of “roundoff” filling to a maximum fuel level. The control valve includes two float-operated valve elements which dose serially in response to initial shutoff and final shutoff refueling fuel levels. The initial shutoff partially closes the control valve to create a temporary shutoff-inducing increase in fuel tank pressure. Final shutoff occurs after allowing a few round-off “clicks” of the filler nozzle to fully close venting through the control valve.

Abstract: A wire harness clip for securing D-scrolled wire harness to a panel type mounting surface, for example in an automobile. A clip has an elongated mounting arm with an open-faced D-shape trough formed at one end and a panel-mounting clip such as a Christmas tree clip formed at an opposite end, on a common surface or side of the mounting arm. The trough includes a hinged cover adapted to releasably lock a D-scrolled wire harness into the trough, and in the illustrated embodiment is a generally flat cover spaced from the and generally parallel to the mounting arm in the closed position, and includes a curved ratcheting lock arm which is automatically guided into locking engagement with mating ratchet teeth on an outer surface of the trough for closing the cover in a blind mounting operation. The trough preferably includes a pair of tape positioning tabs extending generally perpendicular to the mounting arm in alignment with the wire harness for pre-mounting the wire harness to the trough by taping.

Abstract: A laundering implement is provided for cleaning an external surface of a vehicle. A plurality of spacers are supportable with respect to a path of travel for a vehicle to be cleaned and are arranged in first and second stacked or sandwiched groups of spacers for oscillating or rotating movement about a common axis of rotation or axial shifting oscillation along a common axis. The spacers are of a color different from that of the rest of the fixed structure of the laundering implement so that when the implement is in operation the moving spacers and cloth elements create an attractive and attention-getting visual effect. The colors of the spacers may be customized to suit the desires of any particular purchaser or operator of the vehicle laundry system. Each spacer has opposite complimentary faces matable with an opposing face of an adjacent spacer. A plurality of cloth elements are interposed between adjacent stacked spacers for movement in concert therewith.

Abstract: An anchor for securing a net cord to a base layer such as carpeting or a thin layer of plastic has a spiral-shaped flange at the end of the anchor which is disposed adjacent the rear surface of the base layer when the anchor is installed. The spiral flange allows the anchor to be mounted to the base layer with a simple twisting motion and without requiring access to the rear surface of the base layer. The anchor is able to swivel freely about its axis yet is highly resistant to being pulled out of the hole. An installation tool has prongs for engaging detent bumps on the anchor and is used by a worker to hold the anchor while it is being mounted the base layer.
