Title: Incremental rotary angle or length sensor - has two coils formed by web pieces having teeth leaving gaps when inserted together
Inventor: HABERLAND RUEDIGER PROF DR ING
IPC: G01D5/245
Filed: 1989-09-20
Abstract: A track with electrically conductive flanges is installed on a stationary carrier. These flanges are arranged in groups.  Another track with conductive flanges on a movable carrier face the  first track. The flange parts of both tracks form a variable capacitative arrangement. Using control logic, phase shifted a.c. voltages are applied such that an output signal proportional to the change in capacitance is produced as a periodic mean value representing the angle or length to be determined. The coils are formed as interdigitating toothed first and second parts (A1,B1;C1,D1).  The a.c. voltages are alternatingly applied to the first (C1) and second (D1) web parts while the other part of the  movable carrier is held at a constant potential. One part (B1) of the fixed carrier is of like phase while the other part (A1) of the fixed carrier is of counter phase. USE/ADVANTAGE - Extremely good resolution of smallest angle or length changes. Effect of distance between carriers remains small.

Filed: 1990-04-09
Abstract: 1. Gas-insulated switchgear for use in mains distribution stations. 2.1 Gas-insulated switchgears are particularly suitable for use in areas where the conditions are confined.

Title: Stroke piston IC engine - has eccentric thrust crank, with thrust axis of piston power transmission point at opposite to rotation direction by predetermined extent
Inventor: BOEHM ALWIN
IPC: F02B75/02
Filed: 1990-04-30
Abstract: In a two or four-stroke internal combustion engine, the thrust axis of the power transmission point of the piston is opposed from the crank centre point to the direction of rotation by a value the extent of which ranges from one tenth to twice the crank radius.

Title: Moisture film thickness control in offset printing -  comparing measured value with required and using closed-loop regulator
Inventor: JOSS WERNER
IPC: B41F33/00
Filed: 1990-09-05
Abstract: An offset printing machine uses a closed loop regulating system to control the moisture thickness on the printing plates.

The thickness produced can be affected by various external effects (29), e.g. air movement.  The film thickness is monitored by a sensor (15) and the generated signal is processed to produce the measured value for comparison. ADVANTAGE - Maintains accurate control of film thickness, throughout printing process.

Title: Optimised lithography for integrated optics - uses rotationally symmetrical write=beam with variable diameter and outwardly increasing intensity
IPC: G03F7/20
Filed: 1991-09-26
Abstract: The lithography uses a rotationally symmetrical write beam with variable diameter and of an outwardly increasing intensity. The write beam is moved along a track using digital beam and table control. The radial intensity distribution of the beam is chosen so that linear movement of the beam results in a track with desired dose distribution. The write beam can be generated statically or dynamically with light, electrons or ions. For dynamic generation the writing speed for the beam profile must be very great w.r.t. the movement of the write beam along the track. ADVANTAGE - Change in track width is easily realised through continuous change of the beam diameter.
