Patent DE-10354297-A1 (DE)
Title: Water purification unit with fine pore filter removing suspended matter and impurities at least to size of bacteria, includes concentrate tank after filter
Inventor: DULGER VIKTOR
IPC: B01D61/18
Filed: 2003-11-20
Abstract: A waste water tank (11) for the dirty concentrate follows the filter. Its drain line (13) is lower than the filter (6) and higher than its inlet (12). A pressure generator, i.e. a motor-driven dosing pump (4) or hand pump ahead of the filter, forces impure water from the water supply line (1) through the fine pore filter. The pump outlet pressure is 4 bar, 10 bar or more. The equipment is stand-mounted and has a service- or raw water connection. It is alternatively transportable, and has a water supply tank. The inlet (12) of the waste water tank (11) is just above its base. A return line (16) for filtered water is connected into the water supply line. A two-way valve (17) changes-over the filter outlet between the waste water tank and the water supply. There is a separate pressure chamber (5) in the water supply line, preceded by a non-return valve (3). The filter corresponds in fineness with an ultrafiltration membrane or a nanofiltration membrane. An additional activated carbon filter intervenes between the water supply and the interception tank (7). A water sterilizer follows the filter, e.g. in the form of an ultraviolet light radiant.

IPC: B01J13/00
Filed: 1995-02-22
Abstract: A liquid preparation contains micelles which consist of a block copolymer that has at least one polymer block solvating in the solvent and one polymer block bindable for the colloidal metal and which contain colloidal metal enclosed in metallic, oxidic or sulfidic semiconductor form in an organic or inorganic liquid solvent. To produce it, a salt of a metal that can be converted to a colloidal form is added to a solution of the block copolymer in a suitable solvent, forming metallic salt-containing micelles from the block copolymer; the salt is then reduced to form a colloid and the resulting colloidal metal is optionally converted with a sulfide or hydroxide donator to its sulfidic or oxidic semiconductor form or the salt is converted directly to its colloidal sulfidic or oxidic semiconductor form with a sulfide or hydroxide donator.

Patent DE-19534021-A1 (DE)
Title: Non return valve for vehicle fuel tank
Inventor: GRGEC-MESSNER IVAN
IPC: B60K15/03
Filed: 1995-09-14
Abstract: The fuel tank is sealed by a cover (1) which carries the fuel return pipe (6), the fuel feed pipe and the fuel pump. The return pipe is fitted with a membrane (3) valve element which is clamped at one edge and which is pressed onto the valve seat (12). The valve housing limits the open setting of the membrane to prevent inelastic deformation. The membrane can be made of stainless steel for long life operation. It is clamped between support flanges when the valve housing (4) is press fitted to the return pipe duct, with the latter moulded into the cover. The pre-tension in the membrane determines the opening pressure of the return feed and hence the basic pressure in the fuel system.

Title: Chemical-optical laser for military use using single cartridge
IPC: H01S3/095
Filed: 1996-01-16
Abstract: The laser generates a laser beam for use in all operating regions in which other lasers are also operated. The pumping action of the existing radiation of a chemical reaction is used. The existing radiation of a continuous chemical reaction is used to generate a long-duration output beam. The existing radiation of a short-wave chemical reaction is used to generate a laser pulse, whereby the laser active medium can be re-utilised for renewed stimulation by a new reaction. Alternatively, the radiation from a short-wave reaction can be used to generate a laser pulse without re-utilisation of the laser active medium.

Title: Analysis of complex conditions such as multiple gas concentrations
Inventor: GERLACH HARALD
IPC: G01N33/00
Filed: 1996-05-03
Abstract: A sensor system which uses the non-sensitivity of certain sensors can be used to analyse complex conditions such as the concentrations of several different simultaneously-occurring gases. It comprises an evaluation unit, a gas sensor and several other sensors eg. for temperature, air moisture content, pressure, acceleration and sound.
