Title: Signalling circuit for magnetic disc or drum - signals generated when speed exceeds safe limit are applied to flip:flop in set state
IPC: G01P1/10
Filed: 1975-08-13
Abstract: The safety circuit has a reference frequency source whose clock pulses are applied to a counter which, when a specified number is reached, delivers a resetting signal to a safety flip-flop. A signal from an evaluation device showing that the safety limit is exceeded, is applied to the flip-flop in its set state. A stepping signal, generated at each revolution of the magnetic disc or drum, is applied to a further counter. It delivers a setting signal to the safety flip-flop only after it has counted a fixed number of stepping pulses before the appearance of resetting signal from the first counter. A circuit activated either by the setting or resetting signal resets both counters to zero.

Title: Hollow cylinder forming machine - uses interfitting grooved counter rollers and comb to keep joining edges of sheet blank on horizontal tangent
IPC: B21D51/26
Filed: 1977-12-19
Abstract: The bending machine utilises counter rollers (2, 3) and a comb (4) to maintain the (a, b) horizontally tangential without overlap. The counter rollers may have circumferential grooves enabling the internal between their contact zones to be reduced to a practical min. The teeth of the comb may penetrate the grooves of the adjacent counter roller (2), comb movement being initiated when the trailing edge (b) of the sheet passes a proximity detector (5). The arrangement assures bending without terminal deformation when the comb moves at the speed the sheet is unwound.
