Title: Improvements in or relating to variable ratio belt drive mechanism
Inventor: FRY REGINALD STANLEY
IPC: F16H55/56
Filed: 1950-04-17
Abstract: 678,832. Variable-speed gearing. CAMCO (MACHINERY), Ltd. April 17, 1951 [April 17, 1950], No. 9393/50. Class 80 (ii), An expanding conical pulley has the conical flanges 15, 25, of a light weight metal, such as aluminium, and the associated sleeve portions 10, 17, of high duty metal, such as high grade steel. As shown, the sleeve parts 10, 17, are slidably keyed together by a key 20. The flanges 15, 25, are screwed to the sleeves and locked thereon by screws 16, 28, which pass axially through the screw threads between the sleeves and flanges. Solid pegs may replace the screws 16, 28. The flanges 15, 25, are urged towards one another by a spring 33 which abuts an adjustable collar 32 on the sleeve 10 and a collar 22 on the sleeve 17. When changing the gear ratio the distance between the pulley and a cooperating pulley is varied. The pulley is for use in small electric driven machines, such as paper folding and paper handling machinery, and eliminates the harmful effect of centrifugal force set up in the pulley flanges in operation.

Abstract: 1532856 Logic interface circuits NATIONAL SEMICONDUCTOR CORP 11 March 1976 [12 March 1975] 9784/76 Heading H3T A logic circuit (more particularly for interfacing between MOS and TTL busses) of the type comprising an input stage Q2, a buffer stage Q4 and a sink-source output stage Q8, Q9 has a controlled value input current sink Ql for providing an input current switching threshold, means for so disabling the input stage that its input terminal may flow and, as described, means for so disabling the input sink and output stages that both input and output terminals of the circuit may float. When the signal input current at 10 exceeds the demand of Q1 the excess current switches on Q3 and thus switches the output stage. The current demand Q 1 and thus the switching threshold is set by a generator 14 and the diodes in the input circuit together with the one diode voltage drop at the output of 13 limit the input voltage swing substantially to the values 4Vbe and 2Vbe so that switching speed is increased. A disable input to 12 open circuits the base of Q2, turns off the current generator 14 and holds both output transistors off so that both input and output terminals float. Fig. 4 (not shown) is a non-inverting form of the circuit.
