Title: Purifying industrial effluent - by biological oxidn in aeration/oxygenation tank
Inventor: PARSCH HANNS
IPC: C02F3/20
Filed: 1973-01-17
Abstract: Industrial and other waste effluents are purified by accelerated biological oxidn. in a rectangular tank in which the effluent is circulated around a horizontal, perforated partition, while a stream of oxygen and/or air bubbles are released near the base of the tank. The bubbles pass through liq. currents flowing in opposite directions on opposite sides of the partition, each rising bubble being double-deflected to take an extended contacting path to the surface; the oxidising gas is thus used very efficiently and the treatment capacity to size ratio of the plant is high.

Patent DE-2333391-A1 (DE)
Title: Cct. for preventing burnt spots on CRT screen - uses periodical pulse voltage derived from deflection current or voltage as setting pulses for monostable flip-flop
Inventor: JUNG GERHARD
IPC: H04N3/20
Filed: 1973-06-30
Abstract: The burnt spots are caused by failure of deflection current with a TV CRT, or reflection voltage with an oscillograph tube. A periodic pulse voltage is derived from at least one deflection current or voltage, and applied as setting pulses to a monostable flip-flop which automatically resets itself after a time longer than the spacing between two setting pulses. When the flip-flop is reset, it changes one or more supply voltages for the cathode ray tube, so that the beam is defocussed, or weakened, or interrupted. The flip-flop setting pulses are derived by differentiation of the horizontal sawtooth deflection current. The flip-flop resetting time is about 10 to 20% longer than the spacing between the setting pulses.

Patent DE-2445939-A1 (DE)
Title: Ball valve lift restriction system - has cage axis offset from seat axis to turnball gradually
Inventor: STAHLKOPF FRIEDRICH
IPC: F16K29/00
Filed: 1974-09-26
Abstract: The system also induces twisting of the ball, so that it drops back onto its seat in a different attitude each time and wear is thus evened out. The axis of the ring-type cage (3) is offset in relation to that of the seat (2) against which the ball (1) rests, so causing the ball to rotate each time it lifts. This ensures that all surfaces of the sphere eventually come into contact with the seat, and avoids uneven wear occurring at one point on the sphere surface from constant movement and impact against the seat.

Title: Temperature compensation for infra red gas analysers - involves temperature dependent resistor producing signal which compensates for gas temperature changes
Inventor: GATZMANGA HEINZ DIPL CHEM DR
IPC: G01N21/27
Filed: 1974-12-05
Abstract: The output of the infra red gas analyser is fed to a resistor network which includes a temperature dependent resistor (2) with a negative temperature coefficient and a pre-set potentiometer (1). The circuit produces a signal which compensates for errors in the output of the instrument due to changes of the gas temperature. The circuit has the advantage that adjusting the temperature coefficient results in a relatively small change in the total resistance of the network so that the material used to make resistor (2) need not conform to excessively tight tolerances.
