Abstract: A torque assembly includes a spindle, a cap mounted on the spindle for rotation about the spindle, and a work-hardened, plastic sleeve inserted between the cap and the spindle for constant rotation of the sleeve and cap with respect to the spindle. The torque assembly may be installed onto a hinged object and fixed object with movement along a single axis. The torque assembly may be formed by: (a) providing a spindle having a base and a rod extending from the base; (b) providing a cap member with an annular section defining an inner diameter; (c) providing an annular plastic sleeve having an inner diameter and an outer diameter; and (d) work-hardening the sleeve for a predetermined time period by compressing the sleeve between the cap and the spindle.

Abstract: A visor includes a molded polymeric core having a plurality of channels on at least one side defined by a pair of spaced upstanding walls with one of the walls having a plurality of spaced notches formed therein for receiving tabs projecting outwardly from aligned upstanding walls formed in the corresponding mating visor half. The tabs extend into the corresponding slots and the backing wall prevents their removal. Visors embodying another aspect of the present invention integrally include a plurality of outwardly projecting pins and corresponding mating recesses formed continuously around the periphery on opposite visor core halves for compressing the edges of the upholstery material and clamping them in a secure position as the visor halves are brought together during manufacturing.

Abstract: In shot peening apparatus, a device is provided for sensing shot peening intensity and the uniformity of shot flow. It is basically comprised of a detector plate mounted on a cantilevered arm; torque created at the arm mounting due to the impact of shot is measured with a transducer. The detector is mounted on a structure adapted to translate the detector through a large shot peening zone. The invention is especially suited for assuring consistency in a process wherein uniform spherical shot is gravity accelerated to impact a workpiece with uniform velocity.

Abstract: Apparatus for treating workpieces with gravity accelerated shot in which the workpieces are impacted by the impingement of the shot. The apparatus includes unique means for handling the shot to cause it to freely fall and impinge uniformly on the workpieces. This unique means includes the provision for two chambers arranged back-to-back, one containing an elevator assembly which elevates the shot upwardly to the top of the other impact chamber which includes a bucket assembly for catching the shot. The uniformity of the shot stream is created by providing a perforated plate or screen and controlling the depth of the shot above the screen.

Abstract: An improved particle blasting apparatus for continuously monitoring media flow, nozzle wear, and nozzle blockage. The apparatus includes a source of compressed air, a nozzle, structure for conveying the compressed air from the source to the nozzle in an airstream, structure for introducing the media into the airstream to be carried by the airstream, and an air flow rate meter in the air conveying structure to indicate the air flow rate therein. In a preferred embodiment, indicator lights are included which are illuminated if the air flow rate falls outside of an acceptable range. A method of using the particle blasting apparatus is also disclosed.

Abstract: An article or workpiece manipulator mechanism for accelerated shot treating apparatus in which workpieces are subjected to media impingement such as impingement by steel shot. The mechanism manipulates the workpieces within the path or stream of the shot so that desired surfaces of the workpieces are impacted by the shot. This is accomplished by reciprocal or continuous rotation of the workpiece by the manipulator mechanism and also the angle at which the workpiece is held while being rotated can be adjusted by the mechanism.
