Patent DE-3612343-A1 (DE)
Title: Commutation circuit for converters
Inventor: WEH HERBERT PROF DR ING
IPC: H02M7/515
Filed: 1986-04-11
Abstract: The requirement for providing a reactance voltage of commutation which can be adjusted independently of UG and/or is increased can be satisfied using the described booster circuit. Circuits in this form or any similar form make possible better matching of pulse converters to highly utilised machines or to devices which carry alternating current, in the case of which very fast commutation is required. They allow relatively high power densities in the energy converters as well as relatively favourable operating properties. This includes reducing losses and power surges as well as the use of relatively favourable circuit and control concepts which, for their part, lead to further advantageous properties.

Title: Method for operating a composting system
Inventor: STEFFEN HEINZ DR ING
IPC: C05F17/02
Filed: 1986-08-12
Abstract: Method for operating a composting system having a vat which is sealed off from the ground water and in which compostable substances decompose to form compost, the compostable substances being introduced in successive layers into the vat. The individual layers are inserted as inclined sheets which extend from the bottom of the vat up to the prescribed charging level. The sheets inserted in each case are ventilated by means of tubes which are inserted with them, and are therefore initially subjected to aerobic composting in a first zone. Ventilation is discontinued after a period of two to eight weeks. A cover with an airtight surface is mounted on the first zone, so that the aerobically precomposted substances in this zone continue to decompose anaerobically, while in a second zone further compostable substances are placed in sheets in front of the first zone and are ventilated in such a way that they are subjected to aerobic composting, this process being continued, with the zones moving across the vat. The gases generated during anaerobic decomposition are drawn off from a zone which is sealed off in an airtight fashion at the surface and are passed on for utilisation if this is desired. <IMAGE>

Title: Fermenting chamber process for the fermentation of biological waste material
Inventor: HOURANI FARIS
IPC: C05F17/02
Filed: 1986-12-30
Abstract: By fermenting biological waste materials in controlled-environment chambers by the fermentation chamber process, difficulties with composting, which have been a problem so far, are overcome completely. The fermentation chamber process is not only technologically advanced but has also a large number of economical advantages and represents an environmentally friendly and ecological fermentation system. By controlling the fermentation parameters in the controlled-environment chambers, biological procedures and the law of nature are simulated in an optimal fashion. This results in the following novel advantages:     1. Completely odourless fermentation. 2. The shortest fermentation time possible, i.e. 3-6 days as opposed to 3-6 months. 3. Minimum requirements with regard to area combined with better performance (2/3 of the current composting area becomes superfluous).   4. Environmentally friendly, ecological fermentation process in closed chambers.   5. Less investment needed; better quality end products. 6. The composting products can be refined further to give marketable products which can make a profit (Bio-Samad).

Title: Apparatus for the storage and stepwise alteration of the working range of bending machines
Inventor: DOERFEL PETER
IPC: B21D7/12
Filed: 1987-02-16
Abstract: The object of the invention is, by means of an apparatus arranged separate from the bending machine, to reproduce the sequence of motions of the said bending machine and position the individual bending angles. This is achieved by the fact that the movement of the bending machine is transmitted synchronously, by means of a synchro-generator chain, via an electric connection to a synchro-receiver, the rotor of which is connected to a spindle drive. Mounted on the spindle drive, which can be traversed in the X axis, is the positioning rail as the pick-up for the optoelectronic sensors arranged on the Y axis, which serve to sense the position hole on the respective track. The information formation for the off signal takes place when the position is reached, in conjunction with a light source situated on the rear side of the programme card. For initial coding and storage of the bending angles on the programme card, use is made of marking pins situated in the positioning rail and assigned to the individual tracks.

Title: Ski binding for ski jumping
Inventor: DULLEK RUDI
IPC: A63C9/02
Filed: 1987-04-23
Abstract: In conventional ski bindings used in ski jumping, a condition of tension arises because of the angle of incidence of the ski relative to the curve of the drop, and this condition is maintained during the jump by deformations in the region of the ski boot and of the foot. As a result of this, and as a result of excessively high angles of incidence, uncertainties arise on landing and with regard to the length of jump achievable. The ski binding according to the invention permits a free, tensionless pivoting of the ski relative to the base plane of the ski boot and hence the setting of an optimum angle of incidence, aimed at the maximum possible range, of the ski relative to the curve of the drop. <IMAGE>

Title: Tank with water-level indicator
Inventor: BLOCK HUBERT K
IPC: A01G27/00
Filed: 1987-05-29
Abstract: The invention relates to a tank with a water-level indicator for plant-watering purposes (soil cultures and hydrocultures), the tank mainly operating by the subatmospheric-pressure principle, and the water-level indicator being operated by means of deflected pairs of floats. Conventional subatmospheric-pressure tanks do not use water-level indicators, or the only ones proposed are those with a very high display displacement. Furthermore, the tanks are configured in a rather bulky, flat and long manner. They should, however, be narrow and high. The object of the invention is achieved by a tank (1) with a prefabricated base (2). A pivot plate (6) is fastened in the central region of the shaft of the tank. The water level is indicated (21) by said plate by means of the crossbar (7) and the connecting bar (14). The movement (16) is effected by two floating parts (10). The short display displacement of the indicator (12) is possible because the floats (10) are guided along the crossbar (7) and parts move in the form of rockers (16). The viewing-dome shaft (3) has been lengthened some way (4) into the tank interior (20) - for the purpose of better viewing-sleeve guidance (12/21). <IMAGE>
