Title: Fuel tank for vehicles with a pipe leading out of the tank
Inventor: ASCHOFF WOLFGANG
IPC: B60K15/063
Filed: 1993-03-31
Abstract: The intention, in a fuel tank for vehicles with a pipe leading out of the tank, is to reliably prevent fuel from flowing out of the tank through the pipe connection opening in the event of the pipe being torn off due to an accident. For this purpose the pipe connection opening of the tank wall is provided with a valve which, in the event of a deformation of the pipe leading to fracture, automatically closes the opening by means of an actuating element activated by the deformed pipe. In the case of a pipe running in a straight line the actuating element may be a tensioned cable.

Title: Method for the uniform levying of charges at toll stations belonging to different operators
Inventor: ROZEK WERNER
IPC: G07B15/06
Filed: 1993-04-06
Abstract: In a different way from what is known, by means of the method according to the invention charges can be levied, at toll stations belonging to different operators, on a standardized charge-levying principle and with a standard technique by the cancellation of toll-payment units, each operator of a toll station being billed the payment units actually canceled at its toll station. For this purpose, according to the invention, it is necessary that, in each toll station, a date register of the toll-payment units cancelled at this toll station be kept. These toll-payment units are then billed to the operator by a toll-payment centre administering the prepaid toll-payment units.

Patent DE-4319411-A1 (DE)
Inventor: SCHABERT HANS-PETER DIPL ING
IPC: H01M8/247
Filed: 1993-06-14
Abstract: In order to obtain a particularly simple structure for a high-temperature fuel cell installation (1) and a very low power requirement for the compressor (70) on the air side, according to the invention at least one high-temperature fuel cell stack (4 14) in a container (2) forms a gastight separator or a component thereof in the container (2) between an air inlet chamber (28) into which the air inlets from the high-temperature fuel cells open and an air outlet chamber (16) into which the air outlets from the hight-temperature fuel cell open. There is preferably at least one point in this separator at which the air (22) in the air outlet chamber (16) can be at least partially recirculated by means of the air (16) flowing into the air inlet chamber (16). Thus the compressor compresses cold, relatively dense air and the hot air (22) can be recirculated in the container (2) without the addition of moving parts. The invention is essentially applicable to all high-temperature fuel cell installations.

Patent DE-4324428-A1 (DE)
Title: Alumina recovery from material contg. aluminium and impurities of silicon, etc. - by selective removal of impurities by fluorination and chlorination to gaseous cpds., saving energy and avoiding waste disposal problems
Inventor: WILKENING SIEGFRIED DR ING
IPC: C01F7/34
Filed: 1993-07-21
Abstract: Al2O3 recovery from natural or synthetic raw materials (IA) or residues (IB) contg. Al and contaminated with Si, Fe and/or Ti comprises selective removal of the impurities by fluorination and chlorination to gaseous cpds., leaving solid pure Al2O3. The pref. process involves: (a) mixing (I) with a solid fluorinating agent (II), pref. metal fluoride, esp. AlF3 and pref. in stoichiometric excess w.r.t. Si; (b) heating the mixt. to max. 1250 deg.C, so that the water present is expelled and Si is converted to SiF4 gas; (c) reducing the reaction temp. to under 800 or under 850 deg.C; and (d) adding a gaseous chlorinating agent (III), so that impurities forming gaseous chlorides are transferred to the gas phase, leaving pure Al2O3 as residue. ADVANTAGE - The process is more economical than usual, since the specific energy consumption in Al2O3 recovery from e.g. bauxite is lower than in the extn. (Bayer) process, whilst the impurities are converted to useful prods., rather than residues, esp. red mud, which cause difficulties in disposal or use.$ The process can be operated economically with bauxites contg. over 4-5 (wt.)% SiO2. The amt. of type of oxide-hydroxides in the bauxite has little effect on the process, whereas extn. with aq. NaOH soln. is more difficult with samples contg. boehmite (gamma-AlOOH) or diaspore (alpha-AlOOH) than those contg. mainly hydrargillite (Al(OH)3).

Title: Wiper blade with a multi-section supporting frame
Inventor: CRAMER HANS-DIETER ING GRAD
IPC: B60S1/38

Abstract: The proposal is for a wiper blade which serves for cleaning windows/lens glasses on motor vehicles. The wiper blade comprises a multi-section supporting frame to which a driven wiper arm is coupled and which grasps, by means of pairs of claws arranged one behind another on frame parts, the spine of an elongate wiper strip which is made of elastic material and is positioned, by means of a wiper lip, on the window/lens glass to be wiped. The claws of each pair of claws reach into opposite longitudinal grooves arranged in the longitudinal sides of the spine and in that region of the spine which is engaged over by the pairs of claws there are arranged, in the longitudinal sides of said spine, longitudinal channels which lie opposite each other and in which elastic reinforcing rails lie, the length of which approximately corresponds to the length of the spine protruding by its ends out of the outer pairs of claws, and the wiper blade has retaining means which are secured on the wiper strip and secure, in the longitudinal direction, the reinforcing rails in the spine and the wiper strip in the pairs of claws. A particularly easy-to-assemble wiper blade results if each reinforcing rail is provided at one end with a retaining shoulder which interacts with a countershoulder which is arranged on the retaining means which can be attached on this end of the spine and is designed as a one-piece structural element, and if, furthermore, the structural element (lacuna) interacting with the supporting frame and the spine ...

Title: Process for cleaning water effluent with or without biological action
IPC: C02F1/48
Filed: 1994-09-16
Abstract: Cleaning water effluent comprises removing impurities with or without a biological action. The novelty is that energy is introduced into the effluent water by a laser beam or permanent magnet ring. The energy is applied in the effluent water inlet pipe, or in the vessel in which the water effluent is cleaned, and in which it is subject to eddy mixing. The laser beam is directed at the zone between the centre of the eddy and the outer eddy periphery, and parallel to the eddy axis.
