Patent DE-2359689-A1 (DE)
Title: Acceleration indicator for motor vehicles - has two pendula mounted on the same axis in one instrument case
Inventor: BUSCH HEINRICH
IPC: B60Q1/44
Filed: 1973-11-30
Abstract: The pendula automatically consecutively switch on and off two or more circuits. One pendulum is pressed by an elastic element, opposing the centrifugal force, to its zero position. This springy element rests on an arm formed in the hollow pendulum case. The arm saw-tooth shaped edges make possible a quick change of the lever arm length, and thus of the tension applied by the spring to the pendulum. The common axis of the pendula serves as a current conductor, and contacts for incandescent lamps are provided at the case rear wall and connected through a springy conductor to the pendulum axis. These conductors are mounted partly inside the hollow pendulum. Weight in the pendulum lower part is held in position by epoxy resin or similar means.

Title: Tone control using two potentiometers - one pot shunted by capacitor controls LF other pot controls HF ranges
Inventor: WONKA BORIS
IPC: H03G5/10
Filed: 1973-12-06
Abstract: The first potentiometer has a capacitor connected in parallel. The second potentiometer is in series with two capacitors. Its first parallel terminal is the circuit input. Its second parallel terminal is connected to the amplifier output, and its wiper, via decoupling impedances is connected to the amplifier input. The amplifier output is the circuit output. The wiper of the low frequency potentiometer is connected to a centre tapping of the h.f. potentiometer. The special advantage of the control is that the loading of the h.f. regulator by the l.f. regulator is sharply reduced. Sound fidelity and quality is maintained within the audio range.

Title: Ground water-contaminant separation - by submersible pump and separating chamber with snifter pump
Inventor: PERREN BENNO
IPC: E03B3/10
Filed: 1974-03-12
Abstract: A submersible pump system of separating contaminants (petrol or oil) from ground water uses above the pump in the borehole a separating chamber which is sealed against the borehole walls as well as against the submersible pump delivery pipe. Two opto-electric sensors in the separating chamber control a snifter pump to extract just the accumulated contaminant. This achieves a minimum of mixt. between the contaminant and the ground water in the liquid pumped to the surface. Less appts. is needed to separate the contaminant on the surface from the smaller amount of water.

Title: No-voltage switch for unchopped half-waves or wave trains - has capacitor charged by control voltage or impressed current
Inventor: GRIMM OLAF DR ING
IPC: H03K17/13
Filed: 1974-08-03
Abstract: The no-voltage switch has a capacitor discharged during zero crossings, and the capacitor discharge surge is amplified by a transistor which controls a thyristor or a triac. The capacitor (3) is discharged through a switching transistor (4) controlled by mains voltage through a voltage divider consisting of a resistor (6) and a Zener diode (7).

Title: Membrane type hydraulic pump - has spring loaded membrane giving double acting pumping stroke on both sides
Inventor: VEJCHAR LADISLAV
IPC: F04B43/00
Filed: 1974-11-27
Abstract: The membrane has two layers of elastic material between which is inserted a plate spring larger than the opening covered by the membrane. The composite membrane is gripped between te fanges of the opening and the spring forces it to blow out on one side to take a C shape. The membrane is attached to two shaft near opposite ends. As they turn, the lower end of the membrane is deflected to bring the whole into an S shape and then the upper end is deflected to make the membrane bow into a C shape the opposite way. This gives a four stroke motion with one suction and one discharge stroke on each side of the membrane during a complete cycle.

Abstract: Combined productiong of fine-particle coke and fuel gas of high calorific value inf luidised bed or gas stream reactors, by direct addn. of solid fuel to a fuel gas at 850 degrees C min. (pref. 1100-1600 degrees C), produced by a gasificn. process. The solid fuel is decomposed by heating to an average temp. of 500-850 degrees C, into a coking gas which mixes with the carrier gas, and fine coke which is separated from the gas stream. The gas obtained is of high calorific value (around 6000 kcal/Nm3) compared with that from processes using other carrier gases or partial combustion of the solid fuel as the heat source (500-1500 kcal/Nm3) and can be used as fuel gas without expensive pre-treatment. Operating conditions can be adjusted to meet varying gas demands with constant output of coke.
