Abstract: A hydraulic pressure transducer comprises a cylindrical housing having a plurality of circumferential inwardly and outwardly directed ribs which axially position and retain coaxially aligned operative components within the transducer. These components include a hydraulic piston and cylinder, a restoring spring disposed between two centering and retaining stabilizer cups, and a biasing spring which maintains the components in compressed juxtaposition to ensure accurate and immediate response while minimizing axial dimensional stack up. The transducer senses hydraulic pressure in, for example, a brake line and provides a variable resistance output which may be used in an auxiliary electric brake system controller commonly used on recreational trailers and the like.

Abstract: A vehicle wheel assembly comprises a detachable wheel mounted on a radial wheel mounting flange using a single wheel fastener and a conical disc spring to secure the wheel to the wheel mounting flange.The conical disc spring is deflected to a preselected compressed state by the fastener to exert a predetermined axial clamping force uniformly along an annular region of contact between the wheel and the disc spring and to resiliently pre-load the wheel bearings. A lock prevents the single fastener from working loose.

Abstract: A continuous system for separating acceptable from unacceptable synthetic rubber seals and other parts according to their specific gravity comprising a tank having a flotation chamber and an exit or collection chamber. Fluid of a given specific gravity such that the acceptable parts will float therein enters the flotation chamber in such a manner as to produce a rolling or turbulent flow therein. The rolling flow agitates the parts to liberate entrapped air therefrom permitting the parts true buoyancy to float the acceptable parts or sink the unacceptable parts. The floating parts are then swept over an outlet weir into a collection basket by means of a two dimensional fluid flow over said weir.

Abstract: A disc brake for an automotive vehicle having a caliper slidably supported by at least one pin on a stationary supporting member secured to a non-rotatable portion of the vehicle is disclosed. An elastomeric bushing is disposed within a receiving bore through the caliper and contains a low friction bearing slidably receiving the caliper supporting pin therein. Seal means are provided at either end of the bushing to prevent the passage of dirt and other contaminants to the low friction bearing.

Abstract: A method for making a wheel and a wheel so made is disclosed in which the tire bead seats in the rim are deformed inwardly, the wheel is held by the deformed bead seats, and the bolting surfaces of the web are machined in fixed relation to the bead seats. Preferably, the bead seats are deformed sequentially to work welded metal attachment of a web to the rim, and then place it under compression. Preferably, the bolting surface is machined in the form of a flat cone that is approximately three degrees from planar, and the lug holes are chamfered to place surrounding metal in direct compression, and to deform the conically shaped bolting surfaces into flat engagement with planar surfaces on the hubs on which the wheels are to be installed. A method of determined angularity of the web to the rim is utilized to reject poorly aligned webs before machining the bolting surfaces, and thereby prevent undo thinning of the web, and as a means of product control.

Abstract: An insulated vehicle body, such as a refrigerated truck or trailer, has load carrying reinforcement beams in the roof structure with bottom slots accessible through openings in the ceiling skin to receive removable hangers that may be used to suspend meat rails or other articles from the roof structure.

Abstract: The control system for electrically operated brakes utilizes solid state electronic components to control the braking mechanism in a towed vehicle. Energy is provided by a pulsating voltage, the pulse width of which is varied by a pulse width modulator in accordance with the amount of braking effort desired for the vehicle being towed. The pulse width modulator has the width of its output pulse directly controlled by either a hand control, or by a foot pedal control, or in response to the brake hydraulic pressure for the hydraulic brake system of the towing vehicle. Protection against short circuit conditions in the towed vehicle is provided which disables the modulator from producing output pulses for a predetermined period of time. Adjustment of the ratio of braking effort in the towed vehicle to the braking effort in the towing vehicle is provided so as to compensate for different towed vehicle to towing vehicle weight ratios.
