Title: Control system for refuse pelletizing process
IPC: F23G5/02
Filed: 1977-06-27
Abstract: Disclosed herein is a control circuit employing instantaneous and delayed action bistable switching elements for use in controlling the flow of refuse in a multiple channel, extrusion type briquetting or pelletizing system wherein the refuse is supplied from a conveyor to a common chute feeding a pair of extrusion-type compactors. A vane arrangement in the common chute is driven in a reciprocating cyclical manner to feed the refuse in an alternating manner to the compactors. The control circuit disclosed herein senses the cyclical action of the reciprocating vane and controls in turn the conveyor system which supplies refuse to the chute. Certain deviating actions of the vane system indicate conditions signalling an incipient jam in the system flow. The control circuit, in sensing such actions and in concomitantly interrupting the feed of refuse, corrects the feed rate to alleviate the potential jam-producing conditions. Provisions are also included for interrupting refuse feed by excessive compactor pressure sensed by the control circuit.

Title: Solar heating panels
IPC: F24S10/75
Filed: 1978-08-01
Abstract: A solar heating panel is constructed from a kit of parts which essentially comprises a number of absorber plate sections, each of which has on one edge an outwardly-facing concave part-cylindrical portion, the concave surface of which has a radius of curvature equal to the radius of curvature of the outside circumferential surface of the tubes which will carry the water to be heated through the panel.
