Title: Electric battery charging unit - has cyclically switched comparator connected to reference voltage source
Inventor: LEUCHTENBERGER BERND
IPC: H02J7/00
Filed: 1979-04-17
Abstract: Switching off the charge current for a battery in conformity with the actual state of the charge level is ensured by sensing the rise of battery voltage. This is carried out at set time intervals using a comparator (13) which discriminates the battery voltage against a reference source (14). When the voltage rise in the battery is below the given limit, it turns off the unit while overshoot is followed by readjustment of the reference source for rechecking at the next scan using control circuit (16). The monitor (3) is connected to a one-slot multivibrator (4) for resetting, and the charge current is sensed from voltage drop across the resistor (7) connected to an amplifier (8) feeding the difference amplifier (9). The comparator (13) is connected to a control circuit (16) driven by a timer (17).

Title: Combined arc welding - with plasma arc from tungsten needle partly overlapping consumable electrode arc
Inventor: RUSSOLD ALFRED
IPC: B23K28/02
Filed: 1979-06-29
Abstract: An electric arc welding system is based on a first arc between a consumable electrode and the workpiece, and a second plasma arc between a non-consumable electrode and the workpiece. The non-consumable electrode is pref. a tungsten needle which is arranged at a distance from the first electrode and causes the plasma arc to merge partly sideways with the first arc. The partial overlap of the two arcs produces a well defined and stabilized high-temp. zone and fuses the electrode wire always at the same distance from the workpiece. The result is a uniform quality of weld by combining the advantage of both arcs.

Title: Capacitive proximity detonator for shell - uses phase-regulating loop with voltage monitor preventing premature detonation
Inventor: GLATZMAIER GEORG DIPL ING
IPC: F42C13/00
Filed: 1980-03-28
Abstract: The detector uses a pair of relatively insulated electrodes exhibiting a capacitance variation upon proximity to a conductive and/or dielectric object. The electrodes lie in parallel with the frequency tuning capacitor of a voltage controlled oscillator coupled to a phase-regulating loop. This incorporates a phase comparator coupled via a loop filter to one input of the voltage controlled oscillator. The output of the phase comparator is also fed to a monitor storing its output voltage after firing the shell and providing a detoriation signal in response to a capacitance variation only if a given time internal has elapsed.

Title: Heat exchanger driven into soil for heat pump - has filler material between casing and fluid pipes
Inventor: SCHIEDAT HEINZ DIPL ING
IPC: E21B17/18
Filed: 1980-04-19
Abstract: The heat exchanger has a bottom-tapered, closed steel casing (1), intended to be driven into the ground. Inside the steel casing the fluid conducting pipe (3,4) is mounted and the intermediate space between the outside of this pipe and the inside of the steel casing is filled with a cast, heat-conducting material.

Title: Overall cupboard for factory workers - has dirty garment bag in compartment alongside fresh clothes compartment beneath shelves
Inventor: DIPPEL HEINZ GEORG
IPC: A47B61/00
Filed: 1980-07-03
Abstract: The lower part of the cupboard is divided by an upright partition (6) into two chambers (14,15) which are closed by the cupboard doors (40).

Racks engage the outer surfaces of the swing discs, acting as gears. The centrifugal, or centripetal, tracks of the control thread is of variable length in each swing disc, according to the number of equispaced swing discs, possibly exceeding twelve.

Patent DE-3046577-A1 (DE)
Inventor: DOLKEMEYER WILFRIED DIPL ING D
IPC: C10L9/00
Filed: 1980-12-11
Abstract: In this processing method by heating a mixture of raw coal and hydrocarbon oils, a mixture of finely divided raw coal, a hydrocarbon heavy oil and light hydrocarbons are heated at a temperature comprised between 50 and 300`C during 0.1 to 30 minutes; the water and the light hydrocarbons separate simultaneously from the mixture. The light hydrocarbons may be added to the mixture in a closed circuit. There are eliminated from the process on the one hand the water and on the other hand the remaining mixture composed of coal and hydrocarbon heavy oils. By combining in a single phase the heating of the mixture and its separation into its components, the water content of the coal may be considerably reduced. Furthermore, it is easy to proceed in such a way that the mixture of coal and hydrocarbon oils may be conveyed by pumping.

Abstract: Transparent absorption and sound-insulation wall for roads, buildings, offices, with which it is possible to design in a more environmentally friendly manner hitherto known nontransparent sound-insulation wall systems with equivalent acoustic results and which contributes to humanisation of the environment. Since this transparent, fracture-proof sound-insulation wall system can be integrated into the already existing frames, foundations, module sizes and the like, there are no problems during installation. Furthermore, by additional integration of solar collectors into this transparent sound-insulation wall system, solar energy is collected and used to thaw icy roads or heat up adjoining buildings.
