Abstract: This invention relates to a transmission system for applying torque from an engine flywheel (14) to the drive train of an automotive vehicle including a long travel viscous damped torsional damper (40) driven by the flywheel (14) and coupled to a continuously variable transmission (10) which in turn is coupled to a wet drive clutch (26), the output of which is connected to an output counter shaft for the automotive drive train. The long travel torsional damper (40) includes an enclosed, effectively sealed housing (42, 44) containing input and output members coupled through a plurality of series parallel spring sets and immersed in a viscous medium to provide effective viscous damping matched to the effective spring rate of the mechanical damping system to accommodate both transient and steady-­state vibrational torques. The damper is especially useful with the continuously variable transmission but is useful in other applications as well.

Abstract: A full-color holographic screen laminate is disclosed, having a well-defined exit pupil, off-axis viewing capabilities, high and uniform gain, and low backscatter, and in addition the capabilities of blocking the zero-order beam and allowing full-color viewing. The laminate in one preferred form includes several layers, including a plano-convex focusing lens (34), a directional diffraction optics diffusing screen (32), and a thin plane-parallel laminate consisting of a plano-concave cylindrical lens (40), a slanted louver filter (38), and a plano-convex cylindrical lens (42). The lenses (34, 40, 42) can be made out of contrast enhancement material. The louver filter (38) is curved so that the louvers are oriented parallel to the line of sight across the entire louver surface. The plano-convex lens (34) focuses the light, the diffusion screen (32) bends and diffuses the light, the louver filter (38) passes the diffracted light but blocks the zero-order light from entering the ambient, and the contrast enhancement lens (40, 42) increases the overall contrast of the screen (32).

Abstract: A wavefront vector correlation processor (10) for providing rapid, weighted correlation of a given vector with other vectors in a given vector space. In one embodiment the processor (10) includes an interconnected two-dimensional array of simple processing elements (12) that is an electronic analogue of the X,Y plane. Each processing element (12) is connected to neighboring processing elements (12) and is capable of transmitting a pulse to its neighboring elements in reponse to an input pulse. An initial pulse initiated at a processing element (12) having a first classification causes electronic ripples to spread out in chain/reaction among neighboring processing elements (12). When the electronic ripple reaches processing elements (12) having a second classification, a controller circuit (24) senses these events and measures the time between the initial pulse and the detected pulse. This measured time may then be used to provide correlation between the vector of the first classification and vectors having a second classification.

Abstract: A test system for caissons, piles and the like provides an improved way of testing the load bearing capabilities of such inground foundation elements. The test method involves supporting an inertial mass e.g. of concrete rings (30) on the upper end of a columnar foundation element (10) that is installed in the ground and generating in a chamber defined between the underside of the inertial mass and the upper end of the foundation element over a limited duration a propellant gas pressure sufficient to accelerate the inertial mass upwards away from the upper end of the foundation element and at the same time to produce a downwards reaction force of a predetermined desired magnitude on the element. The rate of increase of fluid pressure is controlled such that thereaction force does not damage the foundation element. The magnitude of the downwards force and the response of the foundation element are measured by suitable instrumentation.

Abstract: A turbocharger control system includes an on-off valve (15) disposed in an engine-side end of a passage (13) interconnecting a turbocharger (2) and an engine (1). When the accelerator pedal (5) is released while the engine is in operation, the on-off valve is closed to store air under pressure in the passage. When the engine is accelerated again, the on-off valve is opened to supply the stored air to the engine, thus supercharging the engine. Therefore, any turbocharger time lag produced when the engine is accelerated again can be reduced. If the pressure of intake air stored in the passage is not increased, a motor (3) mounted on the rotatable shaft of the turbocharger is energized to assist in rotating the turbocharger.

Abstract: A fluorescent lamp of this invention includes an ultraviolet reflecting layer (2) of a nonemission material essentially consisting of α-alumina, and a light-emitting layer (3). The nonemission material is a white powder having an average grain size of 0.05 µm to 2 µm. The light-emitting layer (3) is formed on the discharge generation region side of the ultraviolet reflecting layer (2). According to this invention, ultraviolet rays having passed through the light-­emitting layer (3) without being absorbed therein are reflected by the ultraviolet reflecting layer (2) and are radiated onto the light-emitting layer (3) again. For this reason, the light-emitting layer (3) is more frequently excited with the ultraviolet rays to increase a luminous flux.
