Patent DE-3347444-A1 (DE)
Title: Plastic well filter pipe
Inventor: BARAINSKY RUDOLF
IPC: E03B3/18
Filed: 1983-12-29
Abstract: Plastic well filter pipes have a slitting, which runs either parallel or at an angle to the filter axis (pipe axis). It is rectilinear and longer - usually also wider - on the outside then on the inside, because it is made by a circular-saw cut. In contrast to this conventional form, the invention envisages slits which run in a zig-zag or wave form (Fig. 2-h) and are longer (Fig. 2-m/n) and wider (Fig. 2-k/l) on the inside then on the outside, which is made possible by production in injection moulds. <IMAGE>

IPC: F16B12/20
Filed: 1984-05-05
Abstract: A furniture drawer with a front cover that is adjustable and fixable in at least one direction includes connecting hardware having at least two forked gripping members disposed a distance apart. The jaws of the gripping members define an insertion slot and can be pressed together by a closing element. An enlarged head of a web member is engaged by the gripping member. The head is narrower than maximum clearance between the jaws when the head member is inserted into the gripping member. Inclined surfaces are disposed in the region of the said jaws immediately behind the insertion slot and immediately behind the head member and cooperate with projections that abut the inclined surfaces. When the jaws are drawn together, clearances are present between the web member and the outer ends of the jaws, as well as between the head member and the interior regions of the jaws. A first fitting piece outside the drawer front is mounted on the back side of the front cover. The inclined surfaces and projections of the forked gripping member and/or head member, respectively, and the distances of those surfaces and projections from the front cover are mutually arranged so that when the head is inserted in the forked gripping member the front cover is forced against the front surface of the drawer.

Patent DE-3432197-A1 (DE)
Title: Guideway scraper
Inventor: WORM HANS
IPC: F16C29/08
Filed: 1984-09-01
Abstract: Hitherto known guideway scrapers on machines and equipment, which are preferably made of plastic, use a wedge-shaped lip to scrape the guideways clean of dust, dirt and chips. Because the lip wears, the scraping effect diminishes with time. In addition, the scraping effect occurs only in one direction of the backwards and forwards movement. The subject-matter of the invention employs flexible plastic blades which are matched to the profile of the guideway and, in the course of the backwards and forwards movement, brush the guideway in the manner of a paint brush or windscreen wiper. The advantage consists in that both edges of each blade are used for scraping and bend over elastically counter to the direction of movement, reducing wear. The guideway is cleaned in both directions of movement, that is to say during the outward and the return motion.
Patent DE-3439602-A1 (DE)
Title: Flat gasket material, in particular for cylinder head gaskets for internal combustion engines
Inventor: BARTOS VLASTIMIL J DIPL ING
IPC: F16J15/12
Filed: 1984-10-30
Abstract: Flat gasket material, consisting of fibrous and/or fibreless organic and inorganic materials, which are known per se, possibly rolled onto a metal sheet or fabric backing and, after punching and edging, impregnated to improve the cross-sectional impermeability. In order to increase the surface impermeability, which is always a difficult problem for example in the case of cylinder head gaskets in internal combustion engines, a retiform, relatively soft elastomer material is attached by means of an adhesive layer onto the material web prepared for further processing, before punching, or onto finished gaskets before or after impregnation. A filament thickness of 0.1-0.25 mm and a mesh size of approximately 0.8-2.0 mm prove suitable in the case of cylinder head gaskets.

Title: Core-balance transformer for a two-pole or four-pole circuit-breaker with leakage-current tripping for use in a one-phase or three-phase low-voltage distribution system containing a neutral conductor
Inventor: METZ PIERRE
IPC: H01F41/12
Filed: 1985-06-21
Abstract: In a core-balance transformer for a two-pole or four-pole circuit-breaker with leakage-current tripping, whose toroidal core (10) is made of high-quality magnetic material such as, in particular, an iron-nickel alloy, the primary winding conductors (14<1>, 14<2>, 14<3>) made of solid copper wire are insulated with thermally curable epoxy resin, and the toroidal core (10) is formed as an elongated hollow body coated on all sides with curable epoxy resin (12), which hollow body has an essentially constant cross-section over its length and has the smallest possible internal diameter. As a result, the dimensions of the transformer and the material costs thereof can be considerably reduced, and insulating the primary winding can be considerably simplified. Such a core-balance transformer is expediently manufactured by the primary winding conductors, after they have been cut to their final length and bent into their final shape, being coated with the epoxy resin in a conventional fluidized-bed coating process, whereupon all the primary-winding conductors are drawn into the toroidal core which has likewise previously been coated by the fluidized-bed coating process.   <IMAGE>

Inventor: WOLTER HERMANN J DR
IPC: G01N33/566
Filed: 1985-08-28
Abstract: A process for the production of pure, biologically active receptors includes incubating solubilized receptors bound to ligands with ligand antibodies (AK I) attached to a carrier material such as an antibody binding buffer, incubating according to a known process the immobilized receptor-ligand-ligand antibody-complex thus obtained, with a ligand dissociating buffer for example, and the dissolution of the receptor-ligand link. The non-immobilized receptors released are then separated according to a known process and the receptors thus obtained are if necessary purified according to a known process. In another version of the process, the receptor-ligand-ligand antibody-complex is incubated with a carrier material linked in a known manner to antibodies specifically binding the ligand antibodies (AK II). The receptors are released by incubation in a known manner with a ligand dissociating buffer, the receptors of the immobilized ligand-antibody I-antibody II-carrier material-complex are released in a known manner and the pure receptor thus obtained is if necessary further purified in a known manner.

Patent DE-3602592-A1 (DE)
Title: Process and apparatus for reducing peak discharges in rainwater lines or combined-sewage lines
Inventor: STAHN ROLF
IPC: E03F1/00
Filed: 1986-01-29
Abstract: The invention has presented a possibility for reducing discharge peaks in sewage ducts with rainwater channeling. The reduction or delay of rainwater quantities to be channelled away is based partly on direct discharge of rainwater into a receiving-water duct and partly on percolation in a soil filter, including the possibility of feeding the last quantity in a delayed manner to the receiving-water duct. This procedure has the advantage of, at the same time, reducing peak discharges and having two drainage paths for the rainwater discharge, by means of which higher operational reliability is obtained. Moreover, this is combined with the advantage, in comparison with exclusive percolation, of achieving a better flushing effect in ducts which are at risk of deposit formations.
