Title: Applying 3-2 path valve in fluid circuit  of motor vehicle - using valve slide to block respective flow paths in end positions
Inventor: SCHMALENBACH DIETRICH
IPC: F16K11/085
Filed: 1991-07-31
Granted: 1993-03-11
Abstract: The 3/2 way valve (2) used has a translatory adjustable valve slide (10) with two valve discs, respectively tapered in the region determining the vol. flow. Two flow paths are unblocked in selected immediate positions, giving a selective flow ratio, with essentially a constant sum of the two vol. flow. An electric motor servo drive is provided for the valve slide (10) used as a distributor or mixing valve in a liq. circulation system that serves for the heating of the motor vehicle regions, the cooling of these, or serving for the cooling and the heating of motor vehicle regions. ADVANTAGE - Vol. flow remains practically constant independently of intermediate positions taken by valve slider to eliminate falsified flow alterations. At end positions the flow paths are completely closed off.

Title: Correcting or calibrating characteristic curve of sequentially working A=D converter - addressing correction value stored in ROM for each digital internal state of converter
IPC: H03M1/10
Filed: 1991-08-02
Granted: 1993-02-11
Abstract: Each digital word describing the inner state of the analogue-digital converter (ADU) addresses a correction value stored in a ROM and this value is converted into an analogue value by a d-a converter, acting on the quantity placed on the input of the a-d converter. By studying the course of a magnitude representative of the systematic error of the a-d converter in particular the differential or integral non-linearity, the correction values for all the quantisation stages can be calculated in one step. An iterative calculation can be applied and missing codes removed. ADVANTAGE - Essential conditions of conversion are clear and instantaneous step involved can be digitally detected.

Title: Synchromesh gear clutch to shaft in gear change transmission - has frictional, conical clutch with active inner and outer cones, with latter fixed w.r.t. gear change slide sleeve
IPC: F16D23/02
Filed: 1991-12-12
Granted: 1993-02-18
Abstract: This synchroniser and coupling system is to be used in gearboxes to joint a gear with a shaft. The shaft (7) is fitted with two gear wheels (5, 6) separated by a collar or sliding ring (8) and running on roller bearings. The collar can travel axially on an inner fixed ring (16). The axial movement will bring the sloping surfaces of the collar and 'C' shaped synchroniser rings together (9) causing the gear wheels to travel at the same speed as the shaft. Full movement will mesh teeth (14) with the inner teeth of the sliding collar (8) providing positive coupling between gear and shaft. USE - Synchronised gear engagement system for motor vehicle transmission or gearbox.
Patent DE-4201339-C1 (DE)
IPC: B27L5/06
Filed: 1992-01-20
Granted: 1992-07-23
Abstract: In a device for the removal, without shavings, of strips (2) from squared timber (1), an endless feed belt (6) is fitted in an adjustable-height frame (7). The feed belt (6) presses the squared timber (1) in several passes against a blade (5) which cuts off a strip (2) of timber each time. The feed belt (6) is transversely stiffened and has laterally projecting guide components. On both sides of the feed belt (6) there are guide rails on which the projecting guide components are supported to limit the displacement of the feed belt (6) in relation to the blade (5). This prevents the feed belt (6) from contacting the blade (5) once the squared timber (1) has been machined down to a residual thin strip.

Title: AC voltage video signal level measurer - has circuit adding output signals of amplifier and supplying a=d converter assigned to evaluator for control e.g. register
IPC: H03G1/00
Filed: 1992-02-28
Granted: 1993-04-15
Abstract: The input signal (E) to be measured is supplied to a measuring unit e.g. an a-d converter via an amplifying circuit. The degree of amplification is adjusted so that the input to the a-d converter is held constant at a specified level. The amplifying circuit consists of several individual amplifiers (V1-V4) of differing amplification factors. The outputs of the amplifiers are connectable together in any combination in an adding circuit (A) connected to the ADC via controlled switches (S1-S4). An amplified signal can be supplied from one or any number of these amplifiers. The levels of amplification (v) of the parallel connected amplifiers are measured according to the equation v = 2 to the power of (n-1), where n is the number of amplifiers and the associated switches are controlled via a circuit (R), the control output of which corresponds directly to the binary value of the desired amplification. ADVANTAGE - Measuring system can be built cost effectively.
