Patent DE-19520404-A1 (DE)
Title: Diamond grinding tools mfr. using phenolic and polyimide binders
Inventor: WIEMANN HANS-JOACHIM DR
IPC: B24D18/00
Filed: 1995-06-08
Abstract: The process is used to make grinding tools comprising a main body and a grinding coating. The coating consists of hard material grains, such as industrial diamonds or cubic crystals of boron nitride, which are evenly distributed throughout a binder. In the novel process, the tool (1) is immersed in a fluid (3) with a boiling temperature greater than 160 deg C, in an autoclave. There it is isostatically hot-pressed. Also claimed is a grinding tool made in accordance with the process. The fluid, pref. oil, esp. silicone oil, is contained in an open vessel, standing in the autoclave. Before immersion, the grinding layer (5) is coated with a protective film (6); an adhesive may be used for this purpose. Before processing, the grinding layer (5) is converted to a viscid, dough-like state. It is inlaid into one or more preformed grooves (12) in the main body (4). Following the isostatic hot pressing, the main body is turned down and the abrasive is exposed by re-grinding. Hot pressing takes place at a pressure of 150-400 bar, i.e. 1500-4000 Newtons/cm<2>.

Patent DE-19523431-A1 (DE)
Title: Circuit for converting optical signal into electrical signal - has active feedback circuit producing frequency selective filtering of electrical signals from photodiode
Inventor: DERMITZAKIS STEFANOS
IPC: H03K5/08
Filed: 1995-06-28
Abstract: The circuit has a cascode circuit with frequency selective feedback, so that a bandpass characteristic is produced. The lower corner frequency is defined by the feedback components and the upper corner frequency is defined by the transistors. A signal received by a photodiode(FD) is differentiated by a capacitor(Ck), fed to the cascode circuit via two transistors (Q1,Q2) and fed back frequency selectively from the collector of the second transistor (Q2) to the base circuit of the first transistor (Q1). The frequency selective effect is achieved by the introduction of a capacitor (Cq) so that high frequency components are diverted to earth instead of to the input.

Title: Recovering organic materials from a mixture
Inventor: KRUMBHOLZ ERNST RUDOLF
IPC: C07C51/42
Filed: 1995-09-23
Abstract: Process to recover organic materials from a mixt., in which the materials are fed in a supercritical gas or a liquid as a carrier, and passed with this through a chromatography column.  The eluate is then expanded to a pressure and heated to a temp. at which the carrier is gaseous and the substances liquid or solid so they can be separated in different partitions into various fractions.  The eluate to be expanded passes in a small cross section stretched stream, common to all fractions, the substances being separated out successively during the passage of this stream.  The stream is only separated into the various fractions afterwards. Also claimed is a device to carry out the above process, in which the supercritical gas containing the components to be separated is fed to a chromatography column (5) after a pipe coil (10) via a throttle valve (9), with a separator (12) before the coil.

Patent DE-19546056-A1 (DE)
Inventor: MEIER THOMAS
IPC: B60T8/34
Filed: 1995-12-09
Abstract: The invention relates to a hydraulic double-circuit brake system for motor vehicles with a hydraulic high pressure source (5) with a pressure which can be fed via a pedal-operated dosing valve (7) into two brake circuits I and II. The advantage of these brake systems is that one high pressure source is sufficient for any type of braking, i.e. ABS, traction control and standard braking. To achieve active braking in both brake circuits, the high pressure source has to be connectable to the two brake circuits by bypassing the dosing valve (7), while keeping the circuits separate. This is achieved by a valve arrangement (39) which has a check valve in the pressure line (10) from the high pressure source (5) to the brake circuits (I, II), and the pressure line (10) divides into two pressure branches (29, 30) downstream of said valve. The pressure branches are provided with nonreturn valves (31, 32) which prevent return flow of pressure means. It is also possible to provide each pressure branch (29, 30) with a check valve.
