Title: Method of extending the useful life of electrolyte solutions by eliminating interfering organic substances
Inventor: LIEBER HANS-WILHELM PROF DR
IPC: B01J20/34
Filed: 1993-08-27
Abstract: The invention relates to a method of extending the useful life of electrolyte solutions by eliminating interfering organic substances by means of regenerable adsorber polymers. The method is used for treating electrolyte solutions which, for example, are used in the electrolytic deposition of metal coatings and layers and in which the organic constituents of the bath have been converted into undesired byproducts as a result of reactions. An object of the invention is the low-cost elimination of interfering organic substances by means of regenerable adsorbents, primarily using adsorber polymers, with no or only minimal electrolyte losses occurring and the regeneration of the adsorbents being carried out using inorganic acids or alkalis. The complete desorption of the adsorbed mixtures is here achieved by an oxidative pretreatment of the loaded adsorbents and the subsequent regeneration steps.

Title: Heat accumulator combination for hot water prepn. by solar energy
Inventor: LEHMANN THILO
IPC: F24J2/34
Filed: 1994-02-09
Abstract: The combination is such that by solar radiation, the temp. in the collector (K) is raised and recorded by a temp. probe (T1). If the temp. rises above the sea level in the water accumulator (S) and the temp. recorded by the temp. probe (T3), the regulator (R) switches the pump (P1) on, setting the brine circuit in motion. The pump (P2) and the first pump (P1) are provided with a back flow stop, and remain at rest. The heat reaching the collector (K) arrives via a heat exchanger in the user water accumulator (S). The back flow goes through the latent accumulator (L) back to the collector (K). If the temp. in the brine circuit rises above the conversion temp. of the latent accumulator (L), the latent accumulator receives the heat transported in the brine circuit and prevents a further temp. rise.

Title: Twist valve for supplying hydraulic pressure to an adjusting member
Inventor: PFEIFER ARND DIPL ING
IPC: B62D6/02
Filed: 1994-06-15
Abstract: The pressure lines to the hydraulic system, as well as the tank return line, are formed between the input shaft (2) and the valve sleeve. The reaction system consists of a hexagon ring (9) which is attached to the valve sleeve (5) and balls (8), in the input shaft.
