Abstract: A data processor executes a table look-up and interpolate instruction which retrieves two adjacent table values from memory, interpolates between them and stores the result in a register. The same register contains, prior to the execution of the instruction, a value which is used both in calculating the address in memory from which the values are obtained and in performing the interpolation calculation. A major variant of the instruction involves obtaining the values to be interpolated between from registers, rather than from a table in memory. The combination of the two facilitates the performance of three-dimensional, or surface interpolations. It is also possible to select whether rounding is performed during the interpolation.

Abstract: A rear steering system in which a rotary mechanical input obtained from one of the rear wheels is controllably applied to a rear steering rack through an electromagnetic clutch apparatus operated by an electronic control unit. The rotary mechancial input is achieved with a flexible cable gear driven by the rear wheel. The cable provides a rotary mechanical input to a magnetic particle clutch assembly, which in turn, interfaces with the rear steering rack via a bevel gearset. The clutch assembly is controlled by an electronic control unit which responds to a variety of system parameters such as the front and rear rack positions, forward/reverse indication and the speed of the vehicle.

Abstract: The motor current in a vehicle antilock brake system motor driven pressure modulator is increased in stepwise fashion to ramp the brake pressure in the apply phase of an antilock braking cycle. At the beginning of each current step as the motor current is increased in stepwise fashion, the motor torque is increased momentarily at least by an amount to assure that the static friction of the pressure modulator is overcome and that motor rotation is initiated. The motor torque is increased to a value to initiate motor rotation at the beginning of each current step by momentarily increasing the motor current to a value greater than the current step value by a predetermined amount that assures that the increase of motor torque exceeds the static friction of the pressure modulator.

Abstract: Refractory ceramics are provided which comprise at least about 70 mole percent yttrium oxide and from about 5 to 30 mole percent aluminum oxide. The ceramics are particularly resistant to attack by molten rare earth alloys and are superior refractories for use with molten neodymium-iron alloys in the manufacture of permanent magnets.

Abstract: A front or rear bumper fascia for an automotive vehicle in which a series of channels and slots are formed across a support panel of the vehicle body work which allows the bumper fascia to stroke in a fore/aft direction when the bumper assembly is stroked during application of an impact load applied thereto.

Abstract: The present invention provides a four bar linkage seat adjuster apparatus and method of utilization of the same. The seat adjuster includes two links pivotally and cantileveredly connected with the vehicle. A third link is pivotally connected with the first two links and is also connected with the seat. The third link has a latch which selectively sets the position of the third link with respect to the first link thereby determining the position of the seat within the vehicle.

Abstract: A resistance welding electrode for producing spot welds on a workpiece without marring comprises a hollow electrically conductive shank for conducting welding current and pressurized cooling fluid, an electrode head affixed to a rigid, electrically insulating, tubular housing having a flange with a groove and surrounding the free end of the shank, a spring engaging the shank and tubular housing to bias the head out of engagement with the free end of the shank and a ring of resilient, fluid sealing material retained in the groove to engage the shank and form a chamber with the tubular housing and head for cooling fluid from the shank. The ring allows rocking movement of the tubular housing and head relative to the shank so that the workpiece contact area may conform to the workpiece when welding pressure is applied to the shank.

Abstract: A reciprocating piston machine, such as an internal combustion engine, includes a modular power transmission subassembly including a built-up crankshaft, integral unsplit crankshaft journal supports and bolt-less connecting rods to provide a lightweight low cost engine construction. A built-up crankshaft with improved oil lubrication means is also disclosed.

Abstract: An automatic tire mounting and inflation system for successively mounting the upper and lower beads of a tire to a wheel. The system includes a continuously driven conveyor having means for feeding wheels and tires thereon, mounting the tire to the wheel in two successive steps, inflating the wheel mounted tire and removing the same from the conveyor.

Abstract: A headlamp assembly which includes a support bracket that carries a pair of headlamp units in side-by-side relationship and is attached to a support housing at three pivot points so as to allow simultaneous adjustable positioning of the headlamp units about a horizontal axis or a vertical axis.

Abstract: A fuel limit controller includes a computer supplying a commanded absolute EGR control pressure that is a measure of fuel supplied per diesel engine revolution. An absolute EGR control pressure equal to the commanded absolute pressure is generated from a subatmospheric pressure source and atmospheric air so that the absolute EGR control pressure is limited to atmospheric pressure. Fuel per engine revolution is limited to the value represented by the absolute EGR control pressure so that the fuel limit is automatically compensated for altitude variations. The rate of change in the fuel limit in response to changes in the absolute EGR control pressure is limited to delay increases in fuel to match the time to purge excess exhaust gases from the engine intake manifold.

Abstract: A labyrinth seal of abradable design between a shaft and a partition separating regions of high and relatively lower gas pressure. The seal is located in close proximity to a gas permeable bearing also disposed between the shaft and the partition and located in the relatively lower pressure region. The seal permits limited leakage gas flow toward and through the bearing and pieces of seal material abraded during shaft rotation tend to entrain in the leakage gas flow. A baffle is disposed on the shaft between the seal and the bearing and defines a portion of a serpentine path for the leakage gas flow. A contamination trap containing a self-supporting adhesive material is formed on the baffle perpendicular to a portion of the serpentine path so that while the leakage gas turns 90.degree. at the trap, the heavier particles of abraded material impact on and are captured by the adhesive material.

Abstract: A load locking junction device for coupling a continuous-loop belt having ends mounted on the door with an anchor belt retractably mounted inboard the seat includes a frame having an aperture defining spaced apart first and second load bearing walls. The continuous-loop belt is slidable over the first wall to define a lap belt portion and a shoulder belt portion. The anchor belt extends through the aperture and has a pin engaged in the end thereof to enlarge the end for simultaneous engagement against the second wall and the continuous-loop belt so that the belts are coupled together and maintained in engagement with the load bearing walls. A spring acts on the pin to space the anchor belt from the continuous-loop belt to permit movement of the continuous-loop belt through the frame.
