Title: X-ray diagnostic appts. for film exposure series - has automatic exposure meter and dose power meter controlling tube voltage
IPC: H05G1/46
Filed: 1974-09-05
Abstract: The exposure meter terminates each exposure when a given radiation dose for optimum film contrast is reached. The radiation dose controller reduces the X-ray tube voltage when the exposure time falls below a certain limit, and increases it when the exposure time exceeds an upper limit. A manually operated switch preselects the exposure time and disconnects the automatic exposure meter. This connects the radiation dose controller as the exposure meter, so that a nominal signal is applied to it, producing an optimum film blackening. The shortest exposure time is programmed, and can be manually selected by the switch. The automatic exposure meter may be reconnected when the adjusted tube voltage does not provide sufficient film contrast.

Title: Pressure limiting valve with adjustable limit - has external screw and double action seal to provide pressure relief on release
IPC: B60T11/34
Filed: 1974-11-29
Abstract: The valve described limits the fluid pressure supplied to a receiver, to a pre-determined, adjustable value. The description applies to an air brake system regulator, comprising a body (1) in which slides a piston (19) containing a return spring (22) adjusted externally by a nut (23). When air pressure is applied via a union (2), it is transmitted via the valve seat (24) and chamber (13) to the discharge union (3) to actuate the brake. When the limiting pressure is reached it overcomes the spring pressure and forces the piston (19) downwards, thus pressing the valve seat (24) on to the fixed seal (15). The lower flexible lip (31) of this seal is also pressed against the wall (32) and the air cannot then flow to the discharge duct. When inlet pressure is reduced below the limiting value, air flows back via passages (33, 34) displacing the seal lip from the wall. Finally, the spring returns the piston to its upper position.

Patent FR-2264427-A1 (FR)
IPC: H03K3/027
Filed: 1975-02-25
Abstract: A bistable logic circuit generating a stable, preferred output logic state for activating a circuit load having a known response time and capable of being tested while installed and in service without activating the output load includes preferential output state logic memory means, asymmetric delay means and first logic means to generate an output which is the logic product of the memory output and the negation of the circuit Reset input. Second logic means generates the memory means control signal as the logic sum of the circuit Set input and the circuit output asymmetrically delayed by a time period less than the load response time. A test pulse output having a time duration less than the load response time is generated for a set input having a time duration less than one internally determined time period whereby the circuit load is not activated. A load activating output is generated at any time, including the test time period, for a Set input having a time duration greater then another internally determined time period and maintained until a Reset input is solely present.

Title: Electrical safety control for guillotine clamps - has insulated metallic clamp insert which senses skin contact to reverse clamp drive
IPC: F16P3/16
Filed: 1975-03-27
Abstract: A safety guard particularly suitable for a printing industry guillotine controlled by a pedal whose initial action causes the slow descent of a clamp (6) to hold a pile of paper (4) in position. Fitted to the leading edge of the clamp is a metallic strip insert (8) insulated from the metal of the clamp (6). Connections (11, 12) to the insert and the clamp lead to an amplifier (13) which controls the clamp drive. The insert strip is very thin and therefore the distance between it and the clamp is easily bridged by any part of the operator's hand which becomes trapped. If this happens a very small current flows through the skin and is amplified by the amplifier until sufficient to control a relay to reverse the clamp drive motors.
