Title: Bulky scrap crushing and disintegrating machine - uses two interdigitating jaw segments with shredding teeth
Inventor: VOELSKOW PETER
IPC: B02C1/00
Filed: 1977-12-24
Abstract: A machine to break up bulky refuse (domestic articles, trees, pallets, rails and sleepers) consists of two quadrants which form in the position of rest a feed wedge between them. Each has on its periphery segments of alternating radius, carrying lacerating teeth made of tungsten carbide which engage each other. Hydraulic cylinders control their motion either jointly or separately. This machine requires less power than rotary disintegrators and works more economically than power shears. It produces little dust or noise. Two swivelling jaws (1) can be turned around the pivots (4) by hydraulic cylinders. They form a wedge (2) to receive the scrap extended upwards by a shaft (3). The jaws have on their active periphery longer segments (5) carrying lacerating teeth (6) and separated by gaps in which the segments of the other jaw enter. When an obstacle such as a rail cannot be crushed both jaws can be lifted to clear a gap. If a wooden sleeper blocks it one jaw is stopped and the other continues to shred it down with its teeth.

Title: Shaft torque meter with digital read=out - detects phase difference between inductive transducers attached to shaft
Inventor: BROWN WINTHROP KENT
IPC: G01L3/10
Filed: 1978-04-10
Abstract: The shafts torque meter consists of two toothed wheels which are attached to the shaft in question at two different positions(1, 5). The toothed wheels operate in conjunction with inductive pick-up coils(7, 9) whose output pulses are amplified(11, 14) and passed to an exclusive-nor gate(17). The output of this gate is connected to one input of an orgate(20). Its other input is taken from a phase-locked loop (23, 25, 27, 30) connected to the output of one of the pulse amplifiers(14). This amplifier output is divided(40) and drives a hold circuit(45) and, via a delay(43) a counter(37) and divider(35). The phase difference between the two toothed wheels, and thus the torque in the shaft, is converted to pulse form to be processed in the above logic stages. The hold circuit delivers pulses to drive a digital display(53) and an analogue signal is available at the output of a digital-analogue converter(55).

Patent DE-2849919-A1 (DE)
Title: Seven-segment digital display - has light-guide with prismatic total-reflection edge to reduce material content
Inventor: SURBECK HEINZ DR
IPC: G09F9/305
Filed: 1978-11-17
Abstract: The display has a light-guide guiding light from a light source to the display's digits. The edge that totally reflects the light turning it through a given angle has a prismatic shape. The apex angle of the prismatic cross-section is roughly twice as large as the angle of total reflection in the material from which the light guide is made. The prismatic shape reduces the amount of material needed to make the light-guide by permitting a larger angle of incidence for the incoming light beam than is actually possible on the basis of given laws of reflection.
