Title: Overvoltage suppressor with gas-tight housing - has symmetrical electrodes inserted in tubular insulators faces
Inventor: PECHE GERHARD DIPL ING DR
IPC: H01T4/12
Filed: 1973-09-13
Abstract: Overvoltage suppressor with a metal tubular socket has a gas-tight housing in which electrodes in symmetrical opposition are inserted in the face sides of a tubular insulator. The metal tubular socket surrounds the insulator and the electrodes are insulated with respect to the socket. The tubular insulator has on outer edge of its face sides and annular shoulder, adjacent the edges of the electrodes. Thus the middle part of the insulator is provided with an extension exceeding the outer diameter of the electrodes. Between the shoulder and the tubular socket is thus formed an insulating gap. The outer edges of the electrodes may be provided with massive contacts, at least one of which is insulated against the tubular socket.
Patent DE-2348335-A1 (DE)
Title: Desalination system for sea water - by multistage evaporation and incrustation removal by flushing brine of lower concentration
Inventor: SCHWEYER ALFRED DIPL ING
IPC: C02F1/04
Filed: 1973-09-26
Abstract: A desalination system to produce a brine, highly enriched with salts, and fresh water from sea water preheats and condenses the sea water, followed by concentration in several heated evaporators. Each evaporator which shows any incrustation on its heating surface is regenerated by brine, with a lower salt concentration than the brine produced in the evaporator concerned. This has greatly reduced capital costs for evaporators which need not remain free from incrustation but can readily be freed from it.

Title: Motor-driven coffee mill with easily removable grinding mechanism - has side recess corresponding in size to slide member which is fixed by bayonet lock
Inventor: STETTNER GERHARD
IPC: A47J42/16

Title: Composting of refuse and other waste material - by aerobic rotting of the milled and sieved material
Inventor: SPOHN EBERHARD DR ING
IPC: C05F17/00
Filed: 1974-03-28
Abstract: In a process for the working up and composting of refuse or other waste material, the material is ground to a finness such that its glass content has a particle size of 1 mm using a mill with a blast grader, the water-content of the material being held at 30 wt. % and/or its temp. being held at is not 65 degrees C; the ground material is fed to a magnetic separator and a sieve which limits the ground material to a particle size of 20 mm or less; oversize material retained by the grader and the seive is returned to the mill; and the final milled prod. is subjected to aerobic rotting in a conventional manner. Carrying out the milling under the prescribed conditions leads to a particle size analysis such that all of the waste material (except metals removed by the magnetic separator) can be composted, so that no uncompostable residue remains to be disposed of.
Patent DE-2417676-A1 (DE)
Title: Saw-tooth voltage generator for selective calls - has a capacitor slowly charged through a resistor and quickly discharged
Inventor: KOCH KLAUS
IPC: H03K4/84
Filed: 1974-04-11
Abstract: The generator discharge takes place through a transistor circuit which represents an equivalent circuit for a unijunction transistor, and consists of two bipolar complementary transistors. The base of a first transistor controlled by the capacitor voltage through its emitter, is connected to a tapping of a voltage divider across the supply voltage, and to the collector of the second transistor, whose base is connected to the first transistor collector. Its emitter is connected directly or through a resistor to earth. At least the second transistor is inversely operated by interchanging its collector and emitter, and, owing to a much lower gain in such operation, the voltage divider resistance is much higher.
