Patent DE-19629845-A1 (DE)
Inventor: HAUSEN DETLEF
IPC: G05B11/42
Filed: 1996-07-24
Abstract: In order to reduce overshooting of the controlled variable upon rapid changes of the reference variable (w) in a closed-loop control circuit consisting of a PID controller with parallel proportional component (3), integral component (6, 7) and differential component (4, 5), and a controlled system with quasi-integral behavior, the time derivative of the actual value of the controlled variable (y) is fed to the integral component of the PID controller with a negative sign. The PID controller is particularly suitable for automatic control of the r.p.m. of hydraulic secondary units, and for automatic pressure control with hydraulic variable-displacement pumps, and can be implemented simply as a digital controller.

Patent DE-19633682-A1 (DE)
Title: Method of using the power of a flowing medium for energy purposes
Inventor: SCHATZ JUERGEN
IPC: F03D3/04
Filed: 1996-08-12
Abstract: The method involves using flow modules (1) and generating partial rotations about a common axis of rotation using ram pressure and tangential input flows. High and low pressure regions are formed in the parallel flow in the partial rotation regions. One or more eddies are generated in high pressure regions over a continuous or interrupted 360 degrees, forming a helix or disc in a parallel flow. The eddies are formed by flow deflection in the outflow region with the high pressure regions in the inflow region and are screened against the effects of inflow pressure.

Title: Determining elastic properties of active structures in MEMS
Inventor: BSCHORR OSKAR DR
IPC: B81B3/00
Filed: 1996-09-05
Abstract: The method involves determining the elasticity tetrads of the materials from the properties of the elementary cells. The linear, macroscopic elasticity tetrad is derived from the forces occurring at the cell surfaces of a cell, which is deformed when subjected to three translation vectors.  The derivation uses a predetermined equation. The original volume forces in three dimensional linear or plate-shaped structures, idealized as a line or plate of zero thickness, are determined by using a torque vector and an intrinsic counter equilibrium.  Only the force equilibrium is used for real three dimensional structures with spatial force distributions.

Patent DE-19638065-A1 (DE)
Inventor: RICHTER HARALD
IPC: G06T7/00
Filed: 1996-09-18
Abstract: In order to optically control in an automatic manner the quality of tiles and similar products with a reflecting or partially reflecting surface, a colour check and a surface check are carried out. During the colour check, the surface of each tile is recorded by an electronic colour camera, and the colour nuance of the tile is determined from the electric image signals supplied by the colour camera by point-by-point colour classification. During the surface check, the image of a light pattern reflected by the surface of the product is recorded by an electronic camera and the electric image signals supplied by the camera are evaluated to recognise changes in brightness or colour caused by surface defects.
