Patent DE-4405385-A1 (DE)
Title: Electronic equipment preventing unauthorised starting of vehicle
Inventor: ESLINGER BERND DIPL ING
IPC: H04H60/13
Filed: 1994-02-19
Abstract: The electronic device prevents unauthorised operation of vehicles. It has a locking unit for the electric and/or electronic components needed to set the vehicle in motion. The device contains several components which cooperate in the vehicle. The device includes a receiver for a wireless radio service. A decoder delivers binary data transmitted by the radio service at an output. A data monitor receives the data from the decoder and has an arrangement to signal to reception of erroneous data. A non-volatile memory contains at least one code individual to the vehicle (vehicle address). A comparator checks data received directly or indirectly from the decoder for agreement with a vehicle address entered in the memory and provides a signal when these tally.

IPC: H01L21/822
Filed: 1994-03-22
Abstract: First and second material layers having different etching rates (33 and 37, 37b) formed on a source region are partially etched to form a contact hole (39) partially exposing the source region (14). The side portion of the first material layer exposed by the contact hole is partially and isotropically etched to form a "convex space" portion (38). A conductive layer (41) is formed and then patterned so as to form a vase shaped storage electrode (105) (Figure 10, not shown). Then, the remaining first and second material layers are removed, to expose the storage electrode. The storage electrode is formed of a single conductive layer and constituted by a lower portion connected to the source region and a body which extends upwards from the lower portion having a middle portion with at least one convex portion for increasing capacitance. A dielectric film (115) is formed on inner and outer surfaces of the storage electrode and a plate electrode (125) is formed on the dielectric film. The upper, side and bottom surfaces of the storage electrode can be utilized as an effective area of the capacitor. <IMAGE>

Patent DE-4445689-A1 (DE)
Title: Swimming pool water cleaning process recovers unused ozone
Inventor: HAGEN KLAUS DR
IPC: C02F1/66
Filed: 1994-12-21
Abstract: A process to clean and disinfect swimming pool water employs three chambers  through which the water flows in series. The first is a reaction chamber in which ozone is introduced, the second is a stabilising chamber in which the ozone continues to react and the third is a filtration chamber. The novelty is that excess ozone released from the water in the reaction and stabilisation chambers is collected and returned to the reaction chamber. This regenerates the filter by flushing it first with water, then with air, and then again with water. Following rinsing by water, any air is vented from the filtrate collection chamber under the filter before the next water flushing cycle.

Abstract: A process is used to machine workpiece blanks (14) by stock-removal in order to manufacture spiral compressor blades. The blades have at least a spiral wall (13) that extends perpendicularly to a plate (12) having an essentially planar surface (15). In order to minimize the machining time of the workpiece blanks (14) and to optimize the quality of their surface, the workpiece blank (14) is clamped in a CNC-grinding machine (20 to 24, 30 to 34) in such a manner that the surface (15) of the plate (12) stands vertically. The workpiece blank (14) is machined by a tool (30) rotating around a horizontal axis (35) at more than about 30,000 revolutions/minute. A controller (34) modifies the position of the workpiece blank (14) relative to the tool (30) along polar and cartesian coordinates.

Abstract: Dans un procédé pour la réalisation d'un profil d'introduction sur un cathéter à double lumen (1) réalisé dans un matériau élastique et/ou souple et comportant deux lumens non coaxiaux (2, 3) pour l'introduction percutanée dans un vaisseau sanguin, il est prévu qu'à l'extrémité d'introduction, dans la zone d'introduction du cathéter à double lumen, la paroi extérieure du premier lumen (2) soit éloignée dans le sens longitudinal à partir de l'extrémité frontale (5) de telle manière qu'il se forme une zone de transition (7) qui monte progressivement sur la zone non séparée du premier lumen. Dans la paroi de séparation découverte (4a) des lumens, on pratique une coupe (9) ou une ouverture en forme de fente. Cela permet d'introduire, dans le deuxième lumen (3) restant, une canule (15) amenée depuis l'extrémité arrière à travers le premier lumen, jusqu'à ce que la pointe (16) de la canule dépasse de l'extrémité frontale (5) en direction de l'avant. On peut ainsi introduire sans difficulté la canule à double lumen dans un vaisseau sanguin par la méthode connue appliquée pour l'introduction d'un cathéter à un seul lumen.
