Patent DE-4240127-A1 (DE)
Inventor: GMELIN KARL DIPL ING
IPC: F16K1/22
Filed: 1992-11-28
Abstract: In prior art throttle devices the inlet channels are cylindrically formed in the pivoting region of throttle components or there are metering or proportioning venturis which do not affect the air flow at small angles of aperture of the throttle component in the best possible way. The feature of the novel throttle device is its extremely accurately matched metering or proportioning venturis (16, 17) in the region of small angles of aperture of the throttle valve (2) in the intake channel (5) which is achieved by the process of moving a rotating material-removing component (20) with its centre (M) along precalculated paths (B) in the intake channel (5) axially with a radial shift. This process makes it possible to produce the widest variety of outlines of the metering or proportioning venturis (16, 17) in order to achieve desired air-throughput-angle of aperture characteristics. The throttle device is usually used in internal combustion engines preferably fitted to motor vehicles.

Title: Method for generating reference variables for position control loops in numerically controlled machines
Inventor: DEISENROTH JOERG DIPL ING
IPC: G05B19/19
Filed: 1993-02-04
Abstract: A method is proposed for generating a reference variable for a position control loop of a numerically track-controlled machine, desired track values being prescribed by a numerical control system as a sequence of time-discrete control values at discrete sampling intervals (k), from which control values, by means of a filter, discrete desired position values are generated which are fed to the position control loop as reference variables. A desired position value (L(k)) is derived in each case from a sequence of desired track values (L(k-n), v(k-i)), which are suitably weighted. Both desired position values and desired track speed values at preceding sampling intervals enter into the determination of a desired position value (L(k)). The weighting of the desired track values is achieved by multiplying by weighting factors. <IMAGE>
