Patent DE-19638420-A1 (DE)
Title: Hydraulic steering system for commercial vehicles
Inventor: KO HYUN GIE
IPC: B62D6/00
Filed: 1996-09-19
Abstract: The steering system comprises the conventional components in and in addition a secondary electric motor driven pump with its own battery which is brought into operation only if the main pump fails by means of an electronic control unit. The conventional hydraulic steering system consists of a pump (200) feeding hydraulic fluid from a reservoir (204) to a back-pressure valve (210), a priority steering control unit (208), the steering valve unit (216) and the steering control vale unit (220).  A safety hydraulic supply, in the event of failure, is provided by an auxiliary pump (256), the motor of which (250) is energised by a battery (254) controlled by an electronic unit (274) and relay (252), and a valve (260). A compression spring (268) holds the valve normally connected to the fluid reservoir. If the engine is in operation, detected by a sensor (278) and the pressure in the main circuit is low, detected by pressure sensor (276) the electronic control unit switches on the auxiliary pump to feed the steering unit.

Patent DE-19644217-A1 (DE)
Inventor: BACHMANN REINHARD DR
IPC: C08F8/36
Filed: 1996-10-24
Abstract: The invention relates to a process for the preparation of mechanically and osmostically stable high capacitive very acidic cation exchangers with a grain size of >/= 0.1 mm by sulphonation of gel-like or porous pearl polymers with sulphuric acid without using inert chlorine-containing swelling agents and/or of co-monomers based on acrylonitril. The invention proposes that such very acidic cation exchangers can be prepared by sulphonation of gel-like and porous pearl polymers, prepared by copolymerisation of styrene and divinyl benzene with a cross-linker proportion of up to 65 % by weight of divinyl benzene with or without inert agent, with a sulphuric acid concentrated at 80-96 % at temperatures of 125-180  DEG C, the reaction period being of up to 20 h. In the new process, very acidic cation exchangers can be prepared without using the inert, chlorine-containing, ecologically-harmful swelling agent, 1,2 dichloroethane, with the same or similar quality features and substance characteristic data as products prepared using conventional processes.
Patent DE-19648209-A1 (DE)
Inventor: HANDGRETINGER RUPERT DR
IPC: A61K35/28
Filed: 1996-11-21
Abstract: A process for selectively eliminating (purging) tumour cells from preparations containing CD34-positive cells using CD44-specific antibodies is disclosed. The invention is based on the surprising discovery that CD34-positive cells, unlike many tumour cells, do not express the variant exons CD44v5 and CD44vt, or only to a very minor extent. A new molecular marker is thus provided by means of which tumour cells that contaminate strain cell preparations can be selectively destroyed. To destroy tumour cells, CD44v-specific antibody molecules can be linked to a cytotoxic agent, for example the exotoxin of the species pseudomonas.

Title: Testing of PCBs using system working with test fingers
Inventor: IOUCHTCHOUK OLEG
IPC: G01R31/309
Filed: 1997-02-03
Abstract: The testing method is carried out after the positioning of a PCB (4) to be tested on a working surface (3). Optical scanning is used and a pattern of test points arranged on the PCB is determined. The deviation, compared to the result obtained with an ideal PCB ideally applied in the test system, is determined. A coordinate system of the testing system is corrected according to the determined deviation. The test fingers (1) are moved according to the corrected coordinate system. During a calibration operation, a coordinate system of a working surface of the test system is established. Determined points in the coordinate system of the working surface are scanned by the test fingers so that, by means of sensors, the movements of the test fingers to the determined points are determined, and are stored as coordinates of the test fingers in a calibration table.

IPC: C03B23/203
Filed: 1997-07-28
Abstract: A viscous glass layer, 1-13 mm thick, flows continuously downward under gravity in a glass melting furnace to a film drawing unit in which the cooling glass layer is drawn and stretched to a thickness of 0.2-0.4 mm and then, as a partly solidified glass film, continues to cool.

Preferred Features: The glass layer may be profiled in the transverse direction in the film drawing unit. Additional material layers may be melted onto the glass layer to form specific products. Glass film may be stacked into layers to form a glass composite with profiled glass layers forming hollow chambers between the layers. Heat resistant plates may comprise layers of differently profiled glass films bonded together. Cylindrical glass films are produced by winding thin glass film onto a cylinder to form a tube of the required thickness.
