Title: Signal processor for document analysis - detects the waveform gradients using electronic cct. with AND-NOT gates
IPC: G06V30/162
Filed: 1973-03-30
Abstract: The signal processing cct. for detection of waveform slope variation, signals varying between two different levels. A circuit at a given instant determines level reached by the signal, and has also a comparator in which the signal is compared with a fixed voltage separating the levels. There is a peak detecting circuit, a memory circuit which records peak levels, a step circuit in parallel with peak detector which receives signal to be processed, to which is added a definite voltage depending upon the profile of the treated vinyl. The comparator is connected to the memory and step circuits and compares the evolution of the two signals received from their peaks, at the same time indicating the instant when the signal passes from on level to another.

Title: Guide for magnetic read write head for data cards - holds head on flexible mounting which follows edge of card
IPC: G06K7/08
Filed: 1973-06-19
Abstract: The magnetic head is flexibly mounted between two leaf springs and has a sliding shoe fastened to it which extends through a gap in the guiding rail of the instrument.

Title: Cooling tower with counter current droplet flow - having slats to induce circular motion in air and water sprays
IPC: F28C1/00
Filed: 1975-03-06
Abstract: Gas-liq. heat exchanger, esp. cooling tower, for water consists of a series of slats arranged in a circle to form a cylinder, so orientated that air or gas flowing between them enters the cylinder tangentially. Inside the cylinder so formed are vertical standpipes with jets arranged tangential to the cylinder. Above the cylinder is a fan to induce air (or gas) motion in the tower. Into this water (or other liq) is pumped via jets from pump and tank. Liq. draining to the base is returned to the tank. The net effect is that air (or gas) migrates to the column centre and so leaves the tower at the top while the finely dispersed water droplets move in counter-current motion to the outside of the tower due to centrifugal force. Maximum heat exchange is thus achieved.

Title: Control cylinder with stroke-controlled adjusting unit - has small lock for adjusting unit during high cylinder pressure
IPC: F16D65/56
Filed: 1975-08-19
Abstract: The control cylinder for vehicle brakes contains a small lock, to block the adjusting unit in its position, when the pressure medium charge for the control cylinder exceeds a certain limit. The lock is actuated by an auxiliary piston (26), which is charged by the charging pressure of the cylinder against a constant force from a spring (30). When used for vehicle disc brakes, the adjusting unit consists of a threaded spindle, supported against the cylinder base and an adjusting nut screwed to it. A spring charges the nut in the direction of control, and a stop formed as a rotary coupling captures the nut on the control piston, against the spring. The lock is formed as a second rotary coupling (21) which when closed prevents the adjusting nut (16) from turning.
