Abstract: A shock absorber mounted electromagnetically operated damper valve which is mounted upon a piston rod and provides a flow path for fluid which bypasses the piston which separates a cylinder of the shock absorber into a pair of fluid containing chambers. The damper valve includes a spool reciprocally mounted within the hollow interior of a housing. A retainer is also received within the hollow interior and includes a restricted orifice which produces a differential pressure across the spool to assist in retaining the spool in a predetermined position in the absence of electromagnetic signal.

Abstract: A magnetic particle damper apparatus is provided for damping motion between two relatively movable members. The damper apparatus comprises first and second conductor members each attachable to one of the relatively movable members. The conductor members are disposed with confronting surfaces having a gap therebetween filled with a quantity of magnetic particles. A magnetic element is attached to one of the conductor members, producing magnetic flux which is substantially confined to a magnetic flux path defined by relatively magnetically permeable regions and relatively magnetically non-permeable regions of the conductor members to flow across the gap and through the magnetic particles. The magnetic field causes the magnetic particles along the flux path to adhere to one another and to the confronting surfaces of the conductor members producing a force opposing relative motion between said movable members and dissipating energy when the conductor members move relative to one another.

Abstract: The present invention provides a novel fastener member, stud, or other threaded member, for engagement with a female member, and the method of assembly thereof. The fastener member has a novel point which facilitates engagement of the fastener member in the threaded bore, greatly reduces the possibility of cross-threading and is especially suited for use in applications involving blind holes or the use of very thin threaded holes. The fastener member has a threaded shank portion. A point is provided at the end of the shank portion and includes an unthreaded radiused portion and a threaded transition portion between the shank portion and the radiused portion. The major diameters of the threads of the transition portion gradually lessen between the opposite ends thereof. The radiused portion can be provided with a truncated end surface.

Abstract: An apparatus for deploying an air bag through an automotive dash panel includes an air bag door integrally formed in the panel and defined by a frangible edge of reduced cross section. A dispenser supports the air bag behind the door. A metal reaction plate is positioned between the air bag and the door. When the air bag inflates it forces the reaction plate to bend around a horizontal hinge line. As the reaction plate rotates it concentrates inflation force along a lower portion of the frangible door edge. This helps predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending.

A lawn mower is pivotally attached to the laterally extending end of the lift arm and is caster-connected relative to the lift arm by a device of an intervening link which is angulated to be at one elevation at the top of the mower and at a lower elevation to the rear of the mower where the connection is made with the tractor lift arm.

Abstract: According to one aspect of the invention, a multi-layer automotive interior trim panel (10) comprises a decorative covering layer (12) and a supportive substrate layer (16). The substrate layer (16) is comprised of a rigid material formed into a predetermined shape for supporting the covering layer. The trim panel also includes an intermediate layer (18) disposed between the covering layer and the supportive substrate layer comprised of cushioning material. The intermediate layer includes a mat (20) of polymeric fibers, with the mat having a plurality of indentations (24) to provide a cushioning effect. A corresponding method for producing the interior trim panel having the three layers includes several steps. The first step is heating the cushion layer (18) to a predetermined temperature. The second step is melting a portion of the polymeric fibers in the cushion layer. The third step is stamping the cushion layer to form the plurality of indentations (24).

Abstract: A gear pump has a housing, a pump shaft supported in a housing wall by a bearing, and a pumping gear supported on the pump shaft which is operable to pump newtonian and non-newtonian liquid of different densities. A relief collection zone is arranged on a low-pressure side of the bearing for collecting leakage liquid passing through the bearing along the shaft. At least two return ducts or bores are provided which connect the collection or relief zone with a suction side of the pump in order to return the collected leakage liquid.

Abstract: An instrument panel of an automotive vehicle includes a rigid retainer preformed with an air bag opening and a recessed ledge extending about the opening. A separately formed door is installed on the opening and hinged to the retainer along one edge. The remaining three edges overlie the ledge to prevent inward movement of the door. The retainer and door are placed in a cavity of a mold tool in spaced relation to an outer skin and foam constituents are reacted therebetween to develop a foam layer. A foam seal is provided at the interface of the ledge and door to prevent the escape of foam past the ledge.

Abstract: A system of inflatable air cells is constructed and installed in a seat at locations that are strategic to the comfort of the user. The air cells are connected to a pump through a manifold which sequentially connects each cell independently to the pump. The manifold controls the flow of fluid in the air cell distribution system by means of a system of valves and senses the pressure in each cell by means of a transducer. A microcomputer is programmed with data representing a desired comfort level for each of the air cells. By sequentially activating individual manifold valves, a pressure signal from the transducer can be generated for each cell. The pressure signals are received by the microcomputer and are correlated with the predetermined comfort data to generate a control signal which activates the pump. In this manner each of the cells can be individually inflated or deflated to the desired pressure level.

Abstract: A low density, epoxy-based intumescent fire resistive coating, having a density below about 1.10 grams/cc, and most preferably below about 1.0 grams/cc, and a method for forming the same, are disclosed. This method includes the steps of forming an epoxy-based intumescent mastic, having minute particles of amorphous silica dispersed therein. The mastic is then sprayed in droplets on at least one surface of a substrate to form a low density mastic coating on the surface. The low density mastic coating then cures to form a low density, intumescent fire resistive coating. Preferably, the method of invention further includes the step of dispersing at least one type of gas within the mastic, or within at least one part of the mastic to further reduce the density of the cured intumescent coating.
