Abstract: An infinitely variable-speed transmission for use in the power train of a motor vehicle has two rotary sheaves and an endless flexible element trained over the sheaves to transmit torque from the flanges of one of the sheaves to the flanges of the other sheave when the one sheave is driven by the prime mover of the vehicle. The flanges have exposed conical surfaces which are frictionally engaged by the exposed end surfaces of pintles forming part of the flexible element when the latter transmits torque. The flanges are hardened, cushioned, roughened and/or otherwise treated at their exposed surfaces to promote the ability of the sheaves to eliminate or reduce noise on contact with the pintles, to stand long periods of use without extensive wear, and/or to transmit pronounced and variable torques.

Abstract: An optical scanning system of the type in which an oscillating mirror located between the focusing lens and the image plane is provided to scan the reflected optical axis of a focusing lens across a flat field, wherein the pivot axis of the mirror is translated during oscillation of the mirror. The pivot axis of the mirror is translated at an angle of 45.degree. with respect to the optical axis of the focusing lens thereby enabling the mirror to be translated at a uniform velocity during scanning to provide a uniform velocity scan.

Abstract: A large format laser scanning system is disclosed that incorporates a compact, wobble free and wavelength insensitive scanning mechanism. The scanning mechanism includes a pentaprism and lens mounted on a rotating frame assembly that is located within a scanning drum. Multiple light beams generated by a light source are passed through the rotating pentaprism and lens to scan a photosensitive medium located on the interior surface of the scanning drum.

Abstract: An assembly and method for monitoring the alignment of a workpiece with respect to a reference. The assembly and method employ an element which preferably comprises a capability for optical phase conjugation. Advantage which can result from the use of the element include enhanced sensitivity to alignment variations for both large and very small angle deviations from the reference.

Abstract: A scanner including a source of coherent light, a radial hologon, a f.theta. lens and a target. Between the light source and the hologon there are means for forming light from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon. Prismatic means are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation. This allows the shape, orientation and size of the beam on the hologon to be optimum for duty cycle of the hologon and for spot size on the target. The prismatic means allows the spot shape and orientation on target to be optimized. The prismatic means tends to introduce undesirable bow into the scan line, therefore the wavelength of the light and the grating factor (n .lambda.

Abstract: A scanner including a source of coherent radiation, a radial hologon, a f.theta. lens and a target. Between the light source and the hologon there are means for forming radiation from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross sectional shape of the beam radial of the axis of rotation of the hologon. Two prisms are provided between the hologon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation. The prisms are mounted in an articulated mount having adjustment means, which allows rotation of the prisms to as to correct both bow in the scan line and incorrect placement of the scan line on the target.

Abstract: A substantially indestructible, long wearing, life preserver teddy bear toy is constructed with a shaped body of foam plastic enveloped in a tough, snug fitting, water repellant, close fitting fabric outer layer so that the body absorbs less than 5% of its total weight when immersed in water and has enough buoyancy to support a child.

Abstract: The present invention is directed to a capacitor device and method of forming same, and more particularly to a monolithic ceramic capacitor incorporating an improved conductive termination arrangement providing a compliant connector for mechanically and electrically connecting the capacitor to a substrate, said termination arrangement providing increased resistance to damage to the capacitor as a result of differential coefficient of expansion between the capacitor and the substrate on which it is mounted.
