Patent DE-4310734-A1 (DE)
Title: Valve actuating mechanism for an internal combustion engine
Inventor: HANNIBAL WILHELM DIPL ING
IPC: F01L1/26
Filed: 1993-04-01
Abstract: A valve actuating mechanism for an internal combustion engine with at least two inlet or exhaust valves per cylinder has two first rocker levers 5, which each actuate one inlet valve respectively and are actuated by a cam 2 and 3 for a lower engine speed range. A second rocker lever 8, which is actuated by a separate cam 7 for the higher engine speed range, is arranged between the first rocker levers 5. The rocker levers 5 and 8 are supported on a common fixed swivel axis 6. The first rocker levers 5 can be connected to the second rocker lever 8 by pistons 12, which are arranged in radial bores 10 in the first rocker levers 5 and can engage in bores 11 in the rocker lever 8 which are aligned therewith. In order to ensure that the bores 10 and 11 align precisely with one another in the longitudinal direction of the swivel axis 6 when the rocker levers are running on the base circles of their cams, the rocker levers are arranged axially displaceable on the swivel axis 6 and are pressed against one another and against a fixed stop 30 by a spring 29. <IMAGE>

Patent DE-4329022-A1 (DE)
Title: Nozzle for gas or liquid burner and production process
Inventor: WELCKER FRIEDRICH ING GRAD
IPC: F23D11/38
Filed: 1993-08-28
Abstract: Process for producing nozzle bores, in particular for small diameter ranges, by the mandrel casting-in process. In the nozzle body, instead of the required nozzle bore a larger bore is made. A casting mandrel having the diameter of the required nozzle bore is positioned at the centre of this bore and a precisely defined quantity of metal, for example lead, is cast in. After solidification of the cast-in metal, the casting mandrel has to be removed, producing the desired nozzle bore and nozzle bore length. This process makes possible cost-effective production of nozzle bores with the most diverse internal-profile shapes.

Patent DE-4405329-A1 (DE)
Inventor: PALEY GREG
IPC: G09G1/16
Filed: 1994-02-21
Abstract: The invention relates to a process for displaying text in the CGA graphic mode on a personal computer screen having on the one hand a processor and a store allocated thereto in which bit patterns of the text characters to be displayed are stored and, on the other, a video card connected to said processor via an external bus and having a video store, the content of which can be displayed on the screen. During text output, a sequence containing two bits establishing the background colour, especially 00, is generated for each subsequent pixel. The stored text character bit pattern is linked to this bit sequence so that whenever there is the bit 0 in the stored bit pattern for the pixel concerned, no change is made and whenever there is the bit 1 in the stored bit for the pixel concerned, a bit sequence containing two bits establishing the desired foreground colour is generated and stored in the video store.

Title: Vehicle propulsion drive control unit release method using release code signal
Inventor: HAEMMERL ANDREAS
IPC: B60R25/24
Filed: 1994-04-21
Abstract: A procedure for releasing a vehicle propulsion control unit uses a comparison between a signal given by the user and an expected coded signal. The release signal is also given at regular intervals afterwards by the code comparator to the control unit. The release signal is generated without further input of the expected coded signal or without previous synchronisation of the control unit to the code comparator. The release signal is scanned by the control unit at a frequency that is higher than its pulse frequency.

Title: Determining speed of flow incorporating light reflecting particles
Inventor: BUETEFISCH KARL-ALOYS DIPL PHY
IPC: G01P5/26
Filed: 1994-07-29
Abstract: The flow speed is determined from the Doppler shifted frequency. The frequency of the monochromatic light (5), with which the particle is to be illuminated by a light slice (4), is continuously determined. The frequency of the respective determination of the speed of the flow (2) is based on the Doppler shifted frequency. The speed determination system includes a laser (6) emitting a laser beam (7), an optical system incorporating a beam splitter, cylindrical lens and a reflector (10,8,9), and an analysis unit (15) for the Doppler shifted frequency, of the laser light slice laterally reflected by the flowing particles. A filter is arranged in the laser beam (7), which only allows the through passage of a certain frequency. The output (23) from a two dimensional video detector (21) is compared in a further analysis unit (13) with the reference light obtained from the beam splitter via a light pipe (12).

Patent DE-4444362-A1 (DE)
Inventor: KNECHT GERHARD DIPL ING
IPC: G01P3/489
Filed: 1994-12-14
Abstract: A process is disclosed for determining the speed of rotation of a revolving part. A sensor (13, 14) supplies a digital signal (15, 16) that reaches one H level (H) and one L level (L) during each complete revolution. A level change detector (19, 20, 30) generates a signal every time the level changes (40, 41, 42). This signal causes an output signal (22) to be generated as a measurement of the speed of rotation. The speed of rotation is determined every time the level changes (40, 41, 42) from the duration (TR) of the preceding complete revolution of the revolving part. This process allows at least two values for the speed of rotation to be obtained during each complete revolution of the revolving part.
