Title: Aerobic composting of household rubbish, sewage sludge, etc. - in which stack is force ventilated in both directions intermittently
Inventor: SCHUETZ MICHAEL DIPL ING DR
IPC: C05F17/02
Filed: 1975-05-09
Abstract: Raw material for composting, such as disintegrated household rubbish and/or sedimented sludge and/or other material, to be composted by artificial aeration, has air circulated through it continuously in different directions; neighbouring ventilation channels being arranged so that of each pair, air is sucked through one whilst being blown through the other. The flow in each channel may be arranged as such and blow alternately; the single fan for each group of ventilation pipes having its direction of motion reversed intermittently. The air sucked in through the heap is vented by way of a deodorising filter and a gas analyser together with an automatic time switch is used to determine and actuate the frequency of flow changeover. Prevents the setting up in the heap of zones of anaerobic decomposition. After eight weeks the compost is ammonia and sulphide free.

Patent DE-2552068-A1 (DE)
Title: IC engine ignition DC transformer - is disconnected during capacitor oscillation and discharge phase by transistor
Inventor: STURZREHM PETER
IPC: F02P3/08
Filed: 1975-11-20
Abstract: A trigger circuit delivers at ignition instant a rectangular pulse of 1 ms duration, which trips transistor and blocks transistors. The transformer is therefore, currentless for 1 ms. In the meantime multivibrator oscillates on its fixed frequency of 3.5 kHz. Oscillation period determined by capacitor and inductance is usually 1 sm or less. The d.c. transformer must, therefore, be disconnected for at least 1 ms, giving the thyristor a recovery time during which charge carriers in its p-n junctions can dissipate. If the rectangular pulse disappears after 1 ms, transistor can again block, so that the capacitor can be charge. The process is repeated during next ignition instant.
Patent DE-2555240-A1 (DE)
Title: Method of transducing nonelectric variables to digital representation - uses pickoff from stepper motor driven marked disc and associated logic
Inventor: BRUEGGEMANN SWEN
IPC: G01D5/244
Filed: 1975-12-09
Abstract: Non-electric variables of various types such as pressure temperature and the like, are converted into a digital representation using a stepper motor and its associated logic. Basically, the variable being measured must displace a pick off (3) by some means, such as by attachment of the pick off to a bellows element (1) in the case of pressure measurement. The pick off is one of four such elements (3, 8, 9, 10) arranged round a marked disc (5) driven from a stepper motor (6) supplied with pulses from a clock generator (14) and a counter register (11). A number of gates (15, 16) and counters (17, 18, 19, 20) are driven by the various signals fed to and derived from this arrangement so that an output display register contains a count which is a measurement of the basic transducer pickoff position and thus of the primary variable input. A number of compensating signal inputs (22) for temperature or pressure correction terms are also provided.
