Abstract: A single unit of the new deployment system includes a housing to which an electric drive motor is externally mounted. The deployment system for each vehicle requires at least a pair of deployment units: one each for right and left wheels. Each unit includes a reversible electric drive motor having an armature shaft; an intermediate drive shaft; a worm axially affixed to the intermediate drive shaft; an output shaft; a shock damper affixed to the output shaft; a worm gear affixed to the shock damper, the worm gear meshing with the worm, and providing rotational locking for said output shaft; and a deployment arm coupled to the output shaft, the deployment arm having rotatably mounted thereto a friction drive disc, said friction drive disc having peripherally attached thereto a plurality of chain segments.

Abstract: An mounting system for chain traction systems installable on wheeled vehicles having a beam or live axle. Includes four threaded coupling nuts, each of which is threadably secured to a threaded end of one of the U-bolt shackles which secure the axle to either a set of leaf springs or to an air bag assembly. A cross plate ties each lateral pair of coupling nuts together. A mounting tube bolts to the cross plates, a mounting plate bolts to the mounting tube, and the traction system components bolt to the mounting plate. Elongated bolt holes provide a wide range of adjustability between the bolted-together components for proper positioning of the mounting bracket within an x-y plane. For adjustability in a “z” direction, spacers of varying thickness may be inserted between the coupling nuts and the cross plates. The components may be welded together when properly positioned.

Abstract: An improved snow chain system for wheeled vehicles that can be rapidly deployed and rapidly retracted, includes a rotatably-mounted friction drive disc having a circumferential edge that is pressure biased against the sidewall of a tire. Multiple arcuate chain attachment plates, which interlock much like a laminar puzzle, are placed end-to-end to form a ring-shaped unit. The ring-shaped unit is held together and to a planar surface on the friction drive disc by a plurality of bolts, each of which passes through a single attachment plate and through the friction drive disc. Each arcuate attachment plate has either one or two chain segments attached thereto. In the case where only a single chain segment is attached, a U-shaped anchoring chain link is welded to the attachment plate. In the case of attachment of a pair of chain segments, a M-shaped anchoring link is employed.

Abstract: A simulator and method of testing a sensor wherein an electron gun mounted n a vacuum chamber directs a stream of electronic onto a target plate made up of a heat sink backing sheet and a heat insulating coating sheet adhered to the backing layer to form small hot spots on the coating sheet. The target plate may be a sheet of copper to which is adhered a coating layer of glass or a sheet of aluminum to which is adhered a coating layer of aluminum oxide. Infrared radiation from the hot spots is collimated and passed through an optical system which forms an image of the hot spots on the sensor to be tested.

Abstract: A solar energy collection and conversion system is disclosed in which a cassegrain mirror system is rotated about a diurnal axis, which axis is adjusted for seasonal variations in the incidence of the sun's rays on the earth's surface. A black body absorption cavity filled with translucent or transparent fluid material is used for direct absorption of the sun's rays. The incident solar energy is absorbed directly by the fluid medium. The fluid within the cavity may be maintained under extremely high pressures and temperatures in order to utilize this fluid as a heat storage medium. Such heat storage is facilitated by apparatus which permits a change in the volume of the reflective cavity in response to the temperature or pressure of the fluid within the cavity.

Abstract: In the copper catalysed oxidation of p-toluic acid to meta-cresol at an elevated temperature the problem of acid sublimation is avoided by oxidizing the para-toluic acid in admixture with benzoic acid.
