Patent number: 6864012Abstract: A recombinator device and associated method for re-acidification of an electrolyte in a flowing electrolyte zinc-bromine battery. The recombinator device receives hydrogen, formed as a result of electrolysis within cell stacks of the zinc-bromine battery, as well as aqueous bromine from the zinc-bromine battery. Upon receipt, the hydrogen and bromine are introduced into a reaction chamber in the recombinator device so as to form hydrobromic acid. The hydrobromic acid is then reintroduced back into the electrolyte of the zinc-bromine battery for re-acidification of same.Type: GrantFiled: October 29, 2001Date of Patent: March 8, 2005Inventor: Gerd Tomazic

Patent number: 5716733Abstract: The invention concerns a method for producing a nondetachable, fluid-tight, and gastight connection between a plate stack (1) and a plate-shaped lateral component (3) of an electrochemical battery, and for spacing this plate stack (1), which is comprised of successive, thin-walled electrode plates with separator plates (4) disposed between each of them; the lateral component (3) is comprised of electrically non-conducting material. According to the invention, the lateral component (3) is guided spaced apart from and parallel to the respective face ends (5) of the electrode plates and separator plates (4) of the plate stack (1). Then the region of the face ends (5) and the side of the lateral component (3) oriented toward the plate stack (1) are simultaneously exposed to a temporary surface heating until they reach melting temperature and are then pressed against each other until the material cools.Type: GrantFiled: March 15, 1996Date of Patent: February 10, 1998Assignee: Elin EBG Elektrotechnik GmbHInventor: Gerd Tomazic

Patent number: 5702842Abstract: A process for charging and discharging zinc/bromine batteries with a plurality of anode and cathode chambers into and from which anolyte or catholyte fluids are fed and drained. Metallic zinc is deposited on the anode and atomic and/or molecular bromine is deposited at the cathode, and bromine is bonded in an only slightly water soluble complex with a complex-forming agent from the aqueous phase. The anolyte and/or catholyte fluids are circulated periodically. The oleophilic cathode phase is separated from the hydrophilic cathode phase. Only the aqueous phase of the catholyte is circulated through the cathode chambers, and the times at which the fluid is circulated is dependent upon the temperature of the anolyte in the anode chambers.Type: GrantFiled: June 23, 1995Date of Patent: December 30, 1997Assignee: Elin Energieanwendung Gesellschaft M.B.H.Inventor: Gerd Tomazic

Patent number: 5391973Abstract: A method is provided for charging a multiplicity of electrochemical storage, such as cells, cell stacks, and/or batteries. For each storage aqueous electrolytic liquids are infed and outfed at least periodically, or continuously, to and from individual anode and cathode spaces in hydraulic parallel circuits. During the charging of each storage, metallic zinc is separated at the cathode as a layer and bromine is separated at the anode which is converted by a complex former dissolved in aqueous electrolyte into a complex which is essentially insoluble in water. Each electrolyte liquid is provided with a separate circuit, a separate supply container, and also pumps. During the charging operation, at a predetermined time intervals the charging state of each of the electrochemical storage is determined, and upon reaching a predetermined value of the charging state of the corresponding electrochemical storage, the charging operation thereof is interrupted.Type: GrantFiled: May 22, 1992Date of Patent: February 21, 1995Assignee: S.E.A.

Patent number: 4554041Abstract: The use of thermally insulated bodies is determined by their insulative properties, on the one hand, and by the economy of their fabrication on the other hand. A particularly simple method for manufacturing a thermally insulated body, e.g. a pipe, with inner and outer shells, especially with metallic inner and outer shells, forming an intermediate space which is filled with porous particulate and/or porous powdered insulating material, evacuated and hermetically sealed consists in first evacuating the intermediate space between the inner and outer shell, maintaining the space under vacuum and then introducing the insulating material from a reservoir maintained under vacuum and sealing the intermediate space.Type: GrantFiled: April 12, 1984Date of Patent: November 19, 1985Assignee: Vereinigte Edelstahlwerke AktiengesellschaftInventors: Kurt Schreier, Karl Bartsch, Helmut Knoll, Gerd Tomazic
