Patent DE-4028292-A1 (DE)
Inventor: FOPPE WERNER
IPC: B61B13/12
Filed: 1990-09-06
Abstract: The magnetic-cushion railway (3) proposed is a high-speed means of transport which travels at supersonic speed through an evacuated tube (2), using magnetic-cushion technology to avoid contact with the tube surface and the vacuum to reduce air resistance. Twin lines (26), with one tube for each direction of travel, run deep underground in a tunnel (1), with evacuated exit lines (27), over which the train is braked, rising to stations (23) on the surface. Re-entry lines (28) descending back to rejoin the main through-line (26) accelerate the train again. This permits trains to travel at high speed and close behind each other in the main through-line, reaching each station without delay. The trains are accelerated away from a station by the catapult effect of atmospheric pressure acting on the rear of the train (3) as it descends over the short descending section of line (28) into the evacuated tube (25) ahead of it, by the action of gravity and the magnet-cushion drive.

Title: Treated sewage water disinfection - by aerating air and ozone, dosing with active carbon@ and applying UV radiation
IPC: C02F1/28
Filed: 1991-06-20
Abstract: To treat water emerging from a sewage treatment process, eliminating germs, the water is mixed with air enriched by ozone, which is extracted after passing through a given reaction stretch. Water is then dosed with finest grain active C which is then filtered out. Filtered water travels through a gulley, with a low water depth, and its surface is subjected to UV radiation. UV radiation is used to generate ozone, for an air and ozone mixt. to be drawn from the water surface for return to the reaction stretch for mixing with the treated water from the sewage plant. UV radiation is reflected from the base of the gulley. Air and ozone mixt. is removed from the water by the active C bed. Finest grain active C is a moist paste, for dosing by dispersion from the supply. The water is sucked through the filter layer, through gravity while under atmospheric pressure. ADVANTAGE - Technique removes germs from the treated water, so that it can be passed safely into drainage ditches and out into the environment.

Patent DE-4212323-A1 (DE)
Inventor: KUENZEL WERNER
IPC: B65D5/70
Filed: 1992-04-13
Abstract: The invention concerns a parallelepiped folding cardboard box for the stockage and dispensing of pourable products, the box having four walls (2, 3, 4) and, joined to each of them, a flexibly jointed bottom and lid (5, 6, 7) plus a push-in tab (13) delimited by a perforated line (14) near the top edge of one wall (3), thus forming a pour opening. The aim of the invention is to improve the functioning and manipulation of the push-in tab which closes off the pour opening, both when the tab is opened and during the time it is left open, as well as when it is closed again. This is achieved by virtue of the fact that at least one score line (16) runs parallel to the top edge of the box about half way up the push-in tab (13).

IPC: B41F27/12
Filed: 1992-04-30
Abstract: The invention relates to a device for operating a clamping bar relative to the tensioning bar of the plate cylinder of a rotary printing machine, particularly a rotary offset sheet printing machine, in which the clamping bar (3) is mounted via individual ball-jointed pins (5) so as to be pivotable relative to the tensioning bar (2) in the manner of a two-arm lever. The ball-jointed pin (5) is supported on the tensioning bar (2) via a disc (15) and a compression spring (16) and it can be moved via a lifting element (9), consisting of a piston (11) and a cylinder bush (10), counter to the force of the compression spring (16) when subjected to a pressure medium. The clamping bar (3) can thus be relieved by remote control relative to the tensioning bar (2), after which the profiled shaft (7) can be turned by applying only very little force. <IMAGE>

Title: Propellant cage of reduced length for sub-calibre shell - results in reduced weight and therefore increased barrel acceleration
Inventor: MEYER JUERGEN DIPL ING
IPC: F42B14/06
Filed: 1992-05-09
Abstract: A propellant cage is for sub-calibre shells, especially impact shells, having a shortened rear part(16). The rear part (16) is arched outwards and extends rearwards from a pressure flange (6) and its accompanying groove(10) in which is seated a guide bond(not shown). The length (22) of the cord carrying length of the propellant cage is defined as being aft of the guide band. The total length (56) includes this length and the length of the shell enclosing zone just aft of the lending flange (7). The ratio of the band carry length (LL) to the total length(SL) is less than 0.5 and preferably less than 0.4. USE/ADVANTAGE - The propellant cage is for use with sub-calibre shells and is intended to be jettisonal once the shell leaves the barrel. Because of the shorte-end rear part of this propellant cage and its outwardly arched shape the shear streases in the drive cage is minimnsed. Therefore material with a lower elasticity modulus can be used, such as plastic. This reduces the combined propellant cage and shell weght, there increasing acceleration within the barrel and hence shell range.
Patent DE-4217677-A1 (DE)
IPC: C30B11/00
Filed: 1992-05-27
Abstract: A process and device for producing thin, strip-shaped monocrystals having an even surface are disclosed, as well as a crystalline material thus produced. In order to achieve high growth speeds when pulling monocrystals from a solvent, locally limited high oversaturations of solvent are generated and maintained stationary, allowing a continuous strip pulling process to be obtained. The high oversaturations are achieved by a locally limited supply of a substance to the solvent out of a gaseous phase. This substance causes at its entrance site an oversaturation of the crystalline material to be pulled, and thus a locally limited crystallisation, and a continuous process is achieved by appropriate measures. The invention is advantageously used for producing thermally and chemically sensitive crystalline materials and for producing strips of substances which are difficult to process, preferably semiconductor materials.
