Patent DE-3901458-A1 (DE)
Inventor: GIESENDORF BERNHARD DR
IPC: G01N33/543
Filed: 1989-01-19
Abstract: The use of water-soluble salts of divalent or trivalent cations in immunochemical methods for detecting and determining an analyte in a sample is described. It is shown that these salts increase the specificity of such determinations, in particular the background signal in solid-phase immunochemical methods in which the detection of the analyte takes place on a solid phase is reduced by addition of one of the said salts.

Title: REverse osmosis membrane used to filter pesticide-contaminated water - using low operating pressure to ensure only moderate desalination and removal of hardness
IPC: C02F1/44
Filed: 1990-03-21
Abstract: A reverse osmosis membrane can be used in a filter station for the filtration of water contaminated with pesticides in the continuous prodn. of water of drinking quality.  An operating pressure of max. 8 bar is applied to the contaminated water side of the membrane. The sepn. of pesticides and their most important break-down prods. (metabolites) occurs with moderate desalination of the contaminated water, total hardness reduction of up to approx. 701 and retention of monovalent ions of up to approx. 501. Pref. the operating pressure is 3-8 bar. Pref. a water-soluble selective complex former or dispersed dissolved adsorbant pref. of mwt up to 500D is continuously dosed in the contaminated water inlet so that the pesticides and their metabolites then bond firmly with the complex former or adsorbant to form an aggregate which is then more than 90% retained by the membrane. USE/ADVANTAGE - Restricting the operating pressure to max.  8 bar enables the pesticides to be removed just as efficiently as previosly, but reduces the desalination effect. There is no need to attach a device for reintroducing hardness and the danger of pptn. of sparingly soluble components (e.g calcium carbonate, calcium sulphate) on the membrane is reduced.

Title: Seat for office - has seat support in two sections with cushion between
Inventor: DEGEN HUGO
IPC: A47C9/00
Filed: 1990-04-25
Abstract: The foot bearing the seat surface of a seat is divided at a distance of 20-30 cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a, 5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1-T3), the mutual rotation between the two foot parts is ensured. - Due to this construction, the seat surface can be sweveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and owing to the mentioned elastic restoring force, the seat part always retuns automatically to its initial position. When the seat is inclined, the then undesired rotation of the upper seat part 5a is prohibited by the friction between its edge area and the compressed brake ring. - (Dwg.3/7)
