Patent DE-3312956-A1 (DE)
Title: Electronic braking device for asynchronous motors
Inventor: BAUSCH EDMUND DIPL ING
IPC: H02P3/24
Filed: 1983-04-11
Abstract: The electronic circuit part of an electronic braking device for asynchronous motors is simplified in that a switch or a contactor, which is used for switching the motor on and off, is integrated into the electronic circuit in such a manner that a contact (preferably the holding (latching) contact of the switch or of the contactor) is located in a circuit which is closed after the motor is switched on and causes the timer to be reset, the timer determining the duration of the braking current. In consequence, not only is it possible to use fewer and cheaper components in the electronic circuit part but a lower potential also results on the contactor, as well as the capability for connecting the motor winding as desired in star or in delta. Effective accident prevention results from additionally supplying the holding coil of the switch or of the contactor through the power supply of the electronic circuit.

Title: Potential electrodes for potential control, for insulation monitoring and for insulation protection of optically transparent insulation in electronic components and equipment
Inventor: HAERTEL VOLKMAR
IPC: H04B10/80
Filed: 1983-06-16
Abstract: In order to reduce considerably safety risks in the electrical isolation, or especially in the safe electrical isolation of electrical circuits, potential electrodes are inserted into optically transparent insulators for potential control, for permanent insulation monitoring, for example in the event of ageing of optical insulators, and for permanent insulation protection. Partial discharges which damage insulation can be partially eliminated, or at least recognised at a very early stage, can be monitored, and protection measures can be initiated in good time to prevent damage to property, animals and people. If potential electrodes are connected to the earth conductor, then, in the event of insulation defects, the charges from electrical breakdowns and flashovers or leakage currents flow away to earth via the potential electrode to the earth conductor, so that a healthy insulation part is always maintained between the transmitter and detector and hence, in the event of a defect, the insulation between the transmitter and protector can be reduced only to a simple basic or operating insulation. The previously normal optical insulators do not ensure this protection. In many cases, it is not possible to avoid reinforced insulation of optically transparent insulators, partially for circuitry reasons, and partially because of earth conductor connection requirements in accordance with some VDE/IEC/CECC equipment specifications, and also the absence of ...

Title: Box for keeping food fresh
Inventor: GEILHAUPT MANFRED DIPL PHYS DR
IPC: B65D81/24
Filed: 1983-06-21
Abstract: Foods such as cheese and sliced meat deteriorate quite quickly. This is also the case if they are kept "loose" in the refrigerator. A major reason for negative, chemical changes in the foods is generally the oxidative decay of fat. A box for keeping food fresh which keeps oxygen, light, moisture and heat away from easily perishable foods is suitable for increasing the possible storage time of the foods considerably. The foods remain fresh for a longer period and the ingredients are preserved.

Title: Spacing device for rolled bars consisting of sectional steel and steel bar
Inventor: RIST KLAUS DIPL ING
IPC: B23Q7/16
Filed: 1983-12-24
Abstract: The object is to provide a spacing device which spaces the angle, T, I and U sections and the round, square-section, hexagonal and flat steel bars which are fed in layers on conveyor tracks to, for example, cold shears and section shears or the like, in such a way that the rolled bars can be deposited in the track lines which are distributed across the width of the conveying track and lead to the entries to the downstream processing machines at different spacings to one another while maintaining their natural sequence, the said spacings being the single spacing or the sum of the spacings of adjacent track lines. The work steps should be programmable and automated. This is achieved by means of a vertically adjustable guide block arranged on a carriage and having a rolled-bar receiving and spacing beam which can be extended transversely to the conveying track and over which there is a push-off beam movable in the same direction and having a push-off rake, there being furthermore arranged on the guide block a vertically adjustable hold-down device and on the carriage a magazine carrier which can be raised separately and has a star-shaped magazine for exchangeable spacing plates - Fig. 1 -. <IMAGE>

Title: Solar energy heating for plant cold-frame box
Inventor: RAMS HERBERT
IPC: A01G9/24
Filed: 1984-01-10
Abstract: The installation serves for additional heating of the earth in cold-frame boxes. Situated in front of and in the cold-frame box are, from south to north, pipes which are laid next to one another in a rising manner and are filled with liquid. The pipe ends in front of the box, which lie deeper, are covered with glass or foil and are insulated towards the bottom, are heated when the sun shines, so that the liquid situated therein is constantly exchanged, according to the principle of gravity, with that which is colder and situated higher. The heat thus supplied brings about an increase in growth of the plants in the soil which is piled on the upper pipe ends. The heat also penetrates into deeper layers and thus creates a good heat cushion for bridging colder days. A great advantage of this installation consists in that the earth in the box no longer has to be moved, like in leaf and manure packings, which always leads to the layered microflora being disturbed and expends much labour. The installation is to a great extent maintenance-free and very environmentally friendly with regard to utilising free solar energy.
