Patent DE-2231855-A1 (DE)
Title: Gas scrubbing tower - with cascaded scloping perforated floors carrying water films,sealed top and bottom
Inventor: MCILVAINE ROBERT L
IPC: B01D47/02
Filed: 1972-06-29
Abstract: The floors slope alternately in opposite directions and the water feed to form the film on the topmost plate is via a trough and weir forming a seal, the transition from each floor to the next being by a chicane type water seal and the bottom plate having a vertical lip close to the side wall of the column so that a viscous seal is formed. The gases fed into the bottom of the tower are constrained to flow upwards only via the perforations in the floors so that they come into maximum contact with the scrubbing liquid and thus the max extraction even of microscopic dust particles is achieved. The upward feed from the collector tank at the base to the feeder trough for the top floor is via a pump and regulator valve.

Title: Frequency control cct. for single sideband receivers - has oscillator actuated by residual carrier to generate demodulating auxiliary oscillations
Inventor: TAUSCHECK EBERHARD DIPL ING
IPC: H03D1/24
Filed: 1973-11-23
Abstract: The auxiliary oscillation for demodulation, has its phase compared with the filtered carrier, producing a control voltage for the oscillator through a variable reactance. A capacitor with small charge and large discharge time constants is inserted as a shunt store into a control loop so that, when the carrier is interrupted by a selective fading, the state of control is maintained. An electronic switch is provided in the control loop, controlled by the output signal of a carrier recognition circuit consisting of a filter, to which a first input of a phase bridge is connected through an oscillating element whose equivalent circuit is a damped series resonant circuit in parallel with a capacitor. Thus two resonant frequencies exist, between which the impedance is inductive, and outside which it is capacitive. The phase bridge second input is connected to the filter through a resistor.

Title: Twin piston seal for pneumatic shock absorber - reduces pressure with metal ring with low friction rubber seal
Inventor: SCHELLE AXEL DIPL ING DR
IPC: F16J15/3236
Filed: 1974-05-16
Abstract: A pneumatic shock absorber for tracked vehicles has a twin piston seal arrangement. Next to the pressure chamber is an elastic metal piston ring of basically rectangular cross section. The ring face which is in contact with the cylinder is coated with a low friction plastic material. The second piston ring is a knife edge seal ring made from rubber. When a low pressure is generated in the shock absorber, the metal piston ring is not effective so that it is left to the rubber ring to seal the piston. When a high air pressure is present, the escaping air starts to flow past the metal ring and the rubber seal. A pressure build up occurs in the space between the two rings which forces the metal ring radially onto the cylinder wall.

Title: Logic for length measurement transducer removes datum requirement - and can make repeated measurements without interruption
Inventor: KREIENSEN KURT
IPC: G01B7/02
Filed: 1974-12-14
Abstract: A network of analogue and digital elements for application to a length measurement analogue transducer is used for measuring the lengths of elements, and requires no datum resetting between measurements. The basic transducer consists of a probe (4) used to test a workpiece or test element (4, 24) and it produces an analogue voltage proportional to the length of that element. When a second element is examined, the display has traditionally shown the sum of the lengths and an arithmetic manipulation has been required. The logic here removes this requirement. This is done by switching in one of these combinations of logic and analogue elements. In the first position, the first measurement is stored in digital form (17) while in the second position the second length is stored (23) (18) again in digital form. In the third position an analogue summation is effected to produce the correct required display (3).
