Patent DE-19541341-A1 (DE)
Title: Tap-changing voltage regulator esp. for discharge-lamp street lighting
IPC: H01F30/02
Filed: 1995-11-06
Abstract: The load section (4) of the auto-transformer winding (2) between the phase line (L) and the connection (5) to the discharge lamp (6) can be bridged by a first switch contact (11). The winding itself can be disconnected by a second switch contact (9) in a bypass line (8). The control section (17) of the winding is in two parts (18, 19), one (18) of which is divided into four sections (I-IV) with individual switch contacts in series (24-27) and parallel (28-31). To adjust the output voltage (U2) the switching is controlled so that the load section of the winding functions as a choke.
Patent DE-19541715-A1 (DE)
Inventor: SCHWERTFEGER FRITZ DR
IPC: C01B33/143
Filed: 1995-11-09
Abstract: The invention concerns a process for preparing organically modified aerogels, in which: a) a silicic acid sol having a pH of </= 4.0 is prepared from an aqueous sodium silicate solution using at least one organic and/or inorganic acid; b) the resultant silicic acid sol is polycondensed to form an SiO2 gel by the addition of a base; c) the gel obtained in step b) is washed with an organic solvent until the water content of the gel is </= 5 wt.%; d) the gel obtained in step c) is surface-silylated; and e) the surface-silylated gel obtained in step d) is dried. The process is characterized in that the at least one acid forms salts with the sodium silicate cations in the silicic acid sol, which salts are difficult to dissolve. Before step b) the salts produced which are difficult to dissolve are precipitated out to the greatest extent possible and separated from the silicic acid sol.

Patent DE-19601172-A1 (DE)
Title: Honeycomb sandwich core structure of paper plastics or fabric
Inventor: PFLUG JOCHEN DIPL ING
IPC: E04C2/36
Filed: 1996-01-15
Abstract: The metal, plastics, fabric or fibre-reinforced body is first folded and cuts made (9) so the sets of web walls (22 and 14,17) are formed at right angles to one another and there limited by cut edges (11,12) and folding edges (5-8) of the flat body. A second group of connecting surfaces (15,18) is thus formed by the folded parts of the body which are folded into the cover plane and are bounded by two or more cut edges (10-12). A third group of connecting surfaces are formed by parts of the body folded off the walls into the flat plane of the cover so as to lie at right angles to first or second groups. The cut edges (21,12) contacting the web walls are glued,soldered or welded to these. The flat body is folded into rectangular corrugations along lines (1-4) so as to form a number of crests(20) and valleys(21) and the cuts(9) in the body give a second series of web walls(14,17) and are in U-shape so the cut edges (11,12) are in acute angle shape to suit the legs of the U cut (9) or again coincide with the fold lines (1-4). The cut edge (10) at the base of the cut(9) necessarily runs normal to the fold lines. The U-shaped cuts (9) are arranged in series along the corrugation crests (20) and/or valleys at intervals so as to point the first group of connecting surfaces (13,16). The web walls (14,17) on the other side should be folded out of the respective creset and/or valley face and thus folded along the tab fold lines (5) into the sandwich core layer.

Inventor: JONNER WOLF-DIETER DIPL ING
IPC: B60T8/48
Filed: 1996-06-07
Abstract: The invention concerns a hydraulic vehicle braking system (10) with an anti-locking and traction control device. It has a main brake cylinder (12), which is connected to a wheel brake cylinder (16). A reversing valve (18) is connected downstream to the main brake cylinder (12) and an intake valve (20) is connected upstream to the wheel brake cyclinder (16).

Patent DE-19631799-A1 (DE)
Title: Reciprocating piston engine with six work strokes
Inventor: BAUCH STEFAN
IPC: F02B75/02
Filed: 1996-08-07
Abstract: The basic four strokes of the engine work as normal, viz. suction, compression, work, expulsion of exhaust gases. The fifth and sixth strokes work as follows:- In the cylinder combustion chamber, on ignition of the air-fuel mixture, there are high temps., which are transmitted as body heat into the exhaust gas and as radiation heat into the surrounding materials. After the fourth stroke, the exhaust valve is closed, and water is sprayed on to it and over the hot combustion chamber using a nozzle. This produces a steam pressure of at least 150 bar. The fifth stroke works therefore as work stroke, and the sixth stroke expels the steam prior to the next mixture induction stroke.

Patent DE-19650627-A1 (DE)
Title: IC engine throttle shaft
Inventor: KOCHS MICHAEL DR
IPC: F02D9/10
Filed: 1996-12-06
Abstract: The throttle shaft (2) carries a plastics trip lever (3) at one end (7). The lever end of the shaft has a conical sector (8) roughened by grooves (9). The lever engages the shaft by plastic or elastic deformation. This deformation is obtained by applying ultrasonic pressure to the shaft and the lever or simply by pressing the lever down onto the cone sector.
