    Abstract: A rack and pinion power steering system 10 is provided and includes a variable orifice valve 22 which controls the flow of fluid in and out of a hydraulic cylinder 20. Variable orifice valve 22 is communicatively coupled to a source of pressurized fluid 30 by use of a conduit 42 and an electronically controlled valve assembly 38. The pressurized fluid received through conduit 42 controls the operation of valve 22. Based upon the pressure of the received fluid, valve 22 selectively increases and decreases the volume of fluid flow in and out of cylinder 20, thereby causing cylinder 20 to have enhanced damping characteristics during certain vehicle operating conditions (e.g., during relatively high vehicle speed operating conditions).

    Abstract: An improved connection through a substrate layer is formed by embedding a conductive element such as a pin on one or more balls or spheres in a thermoplastic material which is preferably a liquid crystal polymer. The substrate may be heated to facilitate the embedding process in which material of the substrate layer is reflowed under pressure to retain the conductive element by means of a preload force. The formation of such connections with either pins or plural conductive elements allows independence of aspect ratio of the connection and, hence, feature size of conductive patterns on the substrate and the thickness of the substrate layer. Perfecting features of the substrate and method and apparatus for forming the substrate, embedding to a selected depth to form protrusions and recesses to assist in registration of a substrate layer with another substrate layer, metallization to form pads, improved connection between metallization patterns on the substrate and the conductive elements, the regulation of pressurization of substrate material by means of differently shaped dimples or a renewable surface and several alternative arrangements for positioning and embedding the conductive elements. Multiple types of conductive elements may be simultaneously embedded to different depths in a single substrate and from either or both sides thereof to form a variety of substrate structures.

    Abstract: An improved supporting leg assembly for laundry tubs, tables and the like. A leg coupler having a tapered, substantially cylindrical socket containing a key therein is placed at each corner on the underside of the tub. A V-shaped leg, bearing a cylindrical tube affixed thereto on the inside of the V-leg at the end which contacts the tub, is placed at each corner of the tub with the tube engaging the socket. Each tube has a slot formed therein at the end which fits into the tubular socket, and the slot and key mate with each other when the leg is set in place. When assembled together, the tub and coupler are in load bearing contact with the top of each section of the V-leg and the top of the cylindrical tube, respectively. The V-legs may be tapered if desired.

    Abstract: A variable damper assembly 10 is provided for use with a vehicle power steering system and includes a variable orifice valve 20 which controls the flow of fluid between one chamber side 30 of the damper assembly to another chamber side 32 of the damper assembly. Variable orifice valve 20 is communicatively coupled to a source of pressurized fluid 110 by use of a conduit 112 and an electronically controlled valve assembly 114. The pressurized fluid received through conduit 112 controls the operation of valve 20. Based upon the pressure of the received fluid, valve 20 selectively increases and reduces the fluid flow rate between chamber sides 30 and 32, thereby causing the damper assembly 10 to have enhanced damping characteristics during certain vehicle operating conditions (e.g., during relatively high vehicle speed operating conditions).

    Abstract: The curing of a resin in a continuous manufacturing process is monitored by a sensor which measures the surface thermal energy of the resin. The surface thermal energy is measured without physically touching the resin. The surface thermal energy measurements are processed and sent to an automatic controller. The controller adjusts either the speed of the resin or the heat applied to the resin or both in order to optimize the curing process.
