Title: Controller for a magnetic wheel of a high-speed magnetic levitation vehicle
Inventor: STEINMETZ GUENTHER
IPC: B60L13/06
Filed: 1984-07-19
Abstract: The invention relates to a controller (4) for a magnet (1) of a magnetic wheel of a high-speed magnetic levitation vehicle in which a controller output voltage (UR) is generated from status variables and a magnet voltage for the magnet (1) to be controlled is generated from the said voltage (UR). In order to be able to design a simple controller both for high-speed journeys and for journeys at low speeds and when hovering, it is proposed according to the invention that the controller (4) be configured for a stable high-speed journey of the magnetic levitation vehicle with high control circuit amplification. A limiter (6) for the controller output voltage (UR) is connected to the controller (4) and generates a new controller voltage (U'R) as a function of the travel speed of the magnetic levitation vehicle and in the same sense as the said output voltage, the said controller voltage (U'R) limiting the maximum permissible control range for the magnet voltage (UM) when travelling slowly and when the magnetic levitation vehicle is in hovering mode. Although instabilities when travelling slowly and when hovering are accepted with such a control concept, the amplitudes which occur due to the limiting of the control range are only very small and tolerable so that, on the whole, the magnetic levitation vehicle behaves in a stable fashion even with these instabilities. <IMAGE>
Patent DE-3427966-A1 (DE)
Title: Coordinated elements as a thermal barrier
Inventor: BRAUN JUAN
IPC: F24J2/40
Filed: 1984-07-28
Abstract: The principles of this invention rely on the fact that frame constructions for doors, windows, staircase railings and other constituent parts of a building, or house, have hollow spaces which are subjected in their direct vicinity to flows of either preheated air or cooled air and thus form part of a thermal barrier. While primary energy sources, such as for example solar energy, or wind energy, are preferred for use in generating electricity, according to Figs. 1 to 7 sensors and other electronic devices can be used for a balanced temperature. In combination with wind power installations, electricity can be used to heat up ceramic parts in the direct vicinity of frame constructions in the case of windows or doors in such a way that such ceramic parts, used as temporary heat accumulators, make important contributions for a temperature balance. Similar to heat-accumulating furnaces, this invention envisages providing heatable hollow spaces as part of a frame construction in the case of windows or doors, or staircase railings. On similar principles, cooled air can flow out of a frame through provided nozzles or openings in such a way that a window, or a door, or a staircase, or other parts of a house can enjoy a temperature balance, or temperature adaptation.

Title: Hydraulic overload safety arrangement for a lifting appliance
Inventor: KOETTER WOLFGANG DIPL ING
IPC: B66C23/90
Filed: 1985-02-01
Abstract: A hydraulic overload safety arrangement (10) for a jib (11), actuated by a hydraulic cylinder (18), of a loading crane is proposed in which a pump (37) can be switched off via a relief valve (49) in order to limit the load moment, the change in the working position increasing the load moment being automatically taken into account as a function of the the position of the controlled jib part (15) relative to the horizontal (21). Arranged on the jib part (15) are hydromechanical load sensors (58) which, in a control-line system (72), lie in series with a safety valve (54) piloting the relief valve (49). The position sensors (58) control the pressure signals allocated to the relief valve (49) in such a way that pivoting movements reducing the load moment can be carried out irrespective of the positive or negative setting angle of the jib part (15), whereas the pump (37) is relieved in working positions increasing the load moment. <IMAGE>

Title: Sound-insulating element
Inventor: ROSTOCK FRITZ PROF DIPL PHYS
IPC: E04B1/84
Filed: 1985-02-06
Abstract: The invention relates to a sound-insulating element which is enclosed in a frame (3) which is open on both sides and in the central plane of which there is located, according to DE-GM 8410741, a sound-reflection panel (4) which has an approximately waffle-type structure. The two open frame sides are covered by means of lightweight covering panels (5, 6) consisting of plastic, sheet metal, lightweight concrete or the like. The cavities between the sound-reflection panel (4) and the covering panels (5, 6) contain accessory ash (7) or other mineral grains having the same properties. In order to obstruct a gravity-related sinking of the accessory ash, in particular just after introducing it, each covering panel (5, 6) is provided with a plurality of rows of cam-like blocking webs (8) which engage from one row into the next and in each case form an angle < 45 DEG with the longitudinal axis of the covering panel. The height of the blocking web (8) can be governed by the distance between covering panel (5, 6) and sound-reflection panel (4). The invention permits the construction of a very narrow sound-insulating element having a low weight but, nevertheless, highly absorbent properties. Since, unlike the known concrete fillings, accessory ash does not corrode steel, lightweight sheet-metal panels can be used as the covering panels (5, 6). <IMAGE>

Title: Method for metrologically determining, displaying and/or evaluating the icing occurring on the cooling plates of an air cooler
Inventor: WILKE KONRAD DR ING
IPC: F25D21/02
Filed: 1985-11-09
Abstract: Method for metrologically determining, displaying and/or evaluating the icing occurring on the cooling plates of an air cooler, which is preferably arranged in a container ship, the air to be cooled being guided past the cooling plates, through which a coolant flows. In order to be possible at an early stage for the icing to be determined and displayed, and for countermeasures to be introduced, the actual temperature values of the air (T1) fed to the air cooler and at the cooling plates (T2) and of the coolant (brine temperature T3) fed to the cooling plates are measured metrologically. The temperature differences between the actual temperature values (T1, T2) of the air fed to the air cooler and at the cooling plates as well as between the actual temperature values (T2, T3) at the cooling plates and of the coolant fed to the cooling plates are determined metrologically and used to generate a display or evaluation signal. <IMAGE>
Patent DE-3544546-A1 (DE)
Inventor: ERNST HANS-HELLMUT DIPL ING
IPC: B60R22/46
Filed: 1985-12-17
Abstract: Belt tensioner (1) for safety belts. To absorb the load in the event of an accident a belt locking device is arranged over the belt tensioning motor (2). In the rest position a belt locking wedge (10) is held out of contact with the belt (15) by a connection with the belt tensioning motor (2). When the motor housing starts to rotate in the case of an accident, the belt locking wedge (10) enters in engagement with the belt as a result of breakage of the weak link (11) and of spring action. As a result of the saw-tooth arrangement (19) on the surface of the belt locking wedge, further belt tensioning is however possible against the direction of the arrow O without any significant resistance. If, after the end of belt tensioning, a load is created in the belt, already after a 2 mm withdrawal the belt locks as the load increases. Neither the belt tensioner nor coiling unit are subjected to loading.

Patent DE-3605723-A1 (DE)
Title: Method and device for conveying solid/liquid mixtures
Inventor: WILHELM FRIEDRICH DR
IPC: F17D1/16
Filed: 1986-02-22
Abstract: The invention relates to a method for conveying solid/liquid mixtures in the form of an extruded slug by means of pressing or pumping devices in closed conveying lines. Such methods are today frequently used in chemical technology, biological technology and environmental protection technology. For example, the pumping of coal/water mixtures with high solids concentrations, e.g. for a method for coal gasification according to the Texaco-Ruhrchemie-Uhde system, and the pumping of dewatered sewage sludges from sewage treatment installations are to be mentioned. In such a method, the energy consumption for conveying the solid/liquid mixture over a given stretch through a given conveying line is to be reduced, the conveyability of a medium, which fluctuates in wide ranges with regard to the dry material content and the composition, with minimum pressure resistance is to be ensured, and the dry material content of the mixtures to be conveyed is to be maximised. This is achieved by the shell region of the extruded slug having a lubricant added to it peripherally from the start of the conveying line. <IMAGE>
