  • Patent number: 7959751
    Abstract: A manufacturing method for producing a unitized composite material has been discovered. An assembly of loose fibers or fiber and fabric combinations is formed where at least one of the layered elements contains a bondable material such as a thermally sensitive bonding fiber. The un-bonded layered assembly is shaped into a wavy form having a repeating wave-like pattern of the desired amplitude and wavelength. The amplitude and wavelength of the repeating waves can be altered such as by changing the relative speeds of a transfer device and an oven wire and the height of the transfer device relative to the height of the oven wire using simple machinery control settings. The shaped assembly is subsequently bonded in an oven or other activation step preserving the wave-like shaping when cooled or removed from the activation effect.

  • Patent number: 7956558
    Abstract: An automatic traction control system is provided for an electric or hybrid-electric vehicle. The automatic traction control system may be used with vehicles using two separately excited motors where the armatures of the motors are connected in series to provide differential control. The automatic traction control system monitors and compares the voltages across the armatures of the two motors. If the voltage differential exceeds a predetermined threshold, it is determined that one of the wheels is spinning and current is diverted from the motor driving the spinning wheel to the motor driving the non-spinning wheel.

  • Patent number: 7955688
    Abstract: A simplified manufacturing technique to directly form a unitized composite structure with at least one relatively flat surface and at least one sinuous element in an internally-bonded unitized composite is provided. A matrix of fibrous and or other materials is deposited in layers which are subsequently formed into corrugated or wave-like shapes and exposed to an activation step. At least one element is composed of a contractive material which shrinks when activated, such as by heating in an oven, to become relatively flat and optionally bonded to at least one other non-contractive layer which remains in a sinuous shape after the activation step.

  • Patent number: 7955468
    Abstract: An infrared light source focuses infrared energy onto a work surface through the open end of a concentrator. The open end of the concentrator includes an elastomeric seal for sealably coupling the end of the concentrator directly to a work piece. Pneumatic pressure is applied through the concentrator and the seal to urge the work pieces together during the heating process to complete the weld. The method of infrared (IR) welding includes the steps of applying concentrated IR energy to at least one thermoplastic member while simultaneously applying pneumatic pressure to the work pieces for welding one member to another.

  • Patent number: 7950262
    Abstract: A guided keeper assembly and method for metal forming dies includes a base having a flat mounting face and at least one marginal fastener aperture to detachably mount the base to an associated die shoe, as well as a central guide aperture. The assembly also includes a guide pin having a central portion closely received in the central guide aperture of the base for precisely guiding reciprocal motion between the die pad and an associated die shoe. The guide pin has an enlarged head at a first end thereof which abuts the mounting face of the base to positively limit travel between the die shoe and the die pad, and a shoulder at the opposite or second end thereof with an alignment mechanism that precisely locates the second end of the guide pin on the die pad. A first fastener extends through the marginal fastener aperture in the base to securely, yet detachably, connect the same with the die shoe. A second fastener securely, yet detachably, connects the second end of the guide pin with the die pad.

  • Patent number: 7926385
    Abstract: A vehicle passive entry side door latch release system engageable with a release cable connected a door latch includes a moveable linkage assembly engageable with the cable, and a motor including an output shaft engaged with a tensioning gear for driving a ratcheting gearwheel rotatably affixed to a coil spring, with the gearwheel including external teeth engageable with a rack affixed to the linkage to move the cable to unlatch the door latch. A pivotable ratcheting pawl may be engageable with the gearwheel to allow or prevent rotation of the gearwheel. Operation of the motor may drive the gear to drive the gearwheel in a rotary direction to energize the spring, and disengagement of the pawl from the gearwheel may allow stored energy in the spring to drive the gearwheel in an opposite rotary direction to thereby drive the rack to move the cable to unlatch the door latch.

  • Patent number: 7926880
    Abstract: A seating construction includes a perimeter frame defining an open area, and a one-piece molded seating component supported on the frame. The seating component includes a plurality of integrally-formed flexible slats defining a support surface over the open area. Resilient wires are coupled to the slats to resiliently support the slats when flexed. The component can be handled as a unit for assembly, and is retained by connecting rods that extend along the side section of the frame, with the slats each rotatably engaging mating bearing structure on the frame. A flex-limiting member in a center of the frame limits the resilient supports to a maximum deflected condition. Tabs on the molded component interconnect the slats and permit one-piece molding, but are either flexible or breakable to permit independent flexing of the slats. Methods related to the above are also disclosed.

  • Patent number: 7926410
    Abstract: A hydraulic system for synchronized movement of multiple cylinders in a horizontal plane includes a bidirectional pump, a shuttle valve cross-connected between pump outlets, flow-control check valves, and control valves which combine to reduce the number of valves in the hydraulic circuit and to reduce total cost of components for the system. The shuttle valve of the hydraulic system provides fluid for resynchronizing extension and retraction of multiple cylinder assemblies without disconnection of lines, provides air removal without disconnection of lines, allows easy addition/refill of hydraulic fluid, and allows excellent control of the extendable cylinder assemblies.

  • Patent number: RE42408
    Abstract: An oil pump for an internal combustion engine includes a pump body with a first gear chamber and a second gear chamber, and a cover mounting to the pump body. The pump also has a check valve and a pressure relief valve in fluid communication with the gear chambers. The oil pump has a supply set of intermeshing involute spur gears in the first gear chamber with nine involute teeth. A return set of intermeshing involute spur gears with the same gear profile as the supply gears is housed in the second gear chamber. Both sets of gears are driven by a common drive shaft so that the pump may be retrofitted to existing engines. The profile of the gears provides for improved pump volume without increasing angular velocity or gear diameter over gears of the prior art. The return gears are deeper than the supply gears to provide an improved supply to return flow ratio.
