Abstract: A system for multiplexing multiple independent signals includes a transmitter, interconnecting medium, and a receiver. The transmitter encodes a waveform with first and second pieces of information for transmission across the interconnecting medium. The receiver determines the first and second pieces of information using the duty cycle and frequency of the waveform.

Abstract: There is disclosed a tire shredding machine of the type having oppositely rotating rotors mounting interdigitated cutting elements, which is particularly adapted for use in the further reduction of relatively large size rubber chips presently produced by use of commercially available primary tire shredding machines. The present machine incorporates an improved segmented knife retention assembly and a stripper or knife cleaning assembly.

Abstract: There is disclosed for use in a machine for shredding scrap automotive tires or the like of the type comprising a pair of oppositely rotating rotors having interdigitated tire cutting discs keyed thereon and replaceable abrasion resistant wearing plates at opposite sides of said disc, an improved means for locking said plates in operative positions on said discs, whereby worn plates may be replaced by new plates from externally of the rotors without requiring costly disassembly and reassembly thereof.

Abstract: A compactly unitized machine for shredding waste automotive vehicle tires or the like comprising a frame, a shredder, a shredded scrap receiving classifier, and an elevator for carrying oversized scraps rejected by the classfier back to the shredder; said frame, shredder, classifier and elevator are of such configurations and are so relatively arranged and supported upon said frame as to comprise a compactly unitized three-dimensionally minimally sized unit. The classifier per se is of improved construction and operating characteristics.

Abstract: There is disclosed in a unitized automotive vehicle tire shredding system a rotating drum type elevator for receiving from a screening device heterogeneously mixed scraps of shredded tires or the like which include components of curvilinear shape and resilient characteristics. The drum carries the scraps to an elevated point of discharge to fall therefrom by gravity into a shredding machine and from there down again upon the screening device. The drum includes an annular trough-like portion for carrying the scrap when deposited into a lower portion thereof upwardly to the point of discharge when the drum is rotated, and a material travel control device comprising a trough-shaped channeler of convergent sectional form having side walls peripherally configured to complement the curvatures of said rim and flange wall members.
