Patent DE-4114804-A1 (DE)
Inventor: SURAUER MICHAEL DIPL ING
IPC: B64G1/44
Filed: 1991-05-07
Abstract: The invention concerns a device for adjusting the position and for compensating interfering torques of a satellite by means of solar pressure torques. The satellite (101) is fitted with two solar generators (104, 105) arranged symmetrically about the main body of the satellite, e.g., on the north and on the south side, which rotate independently of each other about first axes (109, 110) and can be adjustably positioned so that the normals to their surfaces move through a controllable angle  alpha N,  alpha S in the plane of incidence of the sunlight. A servomotor adjusts each solar generator within a given angular range about a second axis of rotation (301, 302), preferably perpendicular to the first axis of rotation, in function of control signals ( beta N,  beta S). Conditions are given for generating solar pressure torques about a first and a third space axis X0, Y0 by adjusting the solar generators in opposite directions about their second axes of rotation and for generating solar pressure torques about a third space axis Z0 by adjusting the solar generators in opposite directions about their third axes of rotation.

Title: Controlling drying process for photographic paper - using temp. measurement at end of drying path to control drier to ensure defined residual moisture amt.
Inventor: BECKMANN LUTZ DIPL ING
IPC: F26B25/22
Filed: 1991-07-01

The temp. of the photographic material is measured contactlessly at the end of the drying path, pref. by three temp. sensors (131,13,133). ADVANTAGE - Sufficiently accurate, while preventing damage to paper surface.

Title: Linear approximation method used with outline fonts - determines number of divisions from curve dimensions to enable font generation time reduction
Inventor: TAKAHASHI SHINGO
IPC: G06T3/00
Filed: 1991-10-16
Abstract: The linear approximation method is for approximately printing a curve defined by two end points and at least one control point. It involves dividing the curve into a number of sections and joining adjacent sections via straight lines. The curve or the resulting partial curve is successively divided into two curve sections. The number of divisions is determined so as to reduce the difference between two values to less than a defined value. One value corresp. to the sum of the lengths of lines from the end points to a point on the curve. The other is the distance between the end points. USE/ADVANTAGE - For use with outline fonts, the linear approximation method can reduce the time required for generation of a font using an optimal number of divisions.

Title: Sludge burning avoiding surplus fuel, for temp. control - using organic matter in predried sludge as fuel with additional air and drying in electrokinetic stage
IPC: C02F11/15
Filed: 1991-12-05
Abstract: The mechanically predried sludge is further dried in an electrokinetic stage (3) and burned in the furnace (5) together with surplus air. A control (9) maintains the firing temp. at a given value by the effective voltage at the electrokinetic drying stage. A further control (11) determines the amt. of air fed into the furnace w.r.t. the measured oxygen value of the exhaust gas, to an air surplus level which gives min. NOx emission. The firing is pref. in an eddy layer furnace (5). The final water extn. is through a sieve centrifuge, belt- or a chamber-filter press. The first control system (9) has a thermal sensor (10) with output signals to the control (9) to reduce the effective voltage at the electrokinetic stage on an increase of furnace temp., and vice versa. The second control system (11) has an oxygen sensor (12), pref. a lambda probe, to register the oxygen content at the exhaust gas, to increase the air feed to the furnace as the oxygen content sinks, and vice versa. ADVANTAGE - Used to give min. NOx emission, and exploits the full furnace capacity.

Title: Surface of upper jaw denture which faces the tongue - has same texture as surface pressed against roof of mouth to avoid irritation
Inventor: KUECHLER DIETER WALTER
IPC: A61C13/24
Filed: 1992-01-21
Abstract: A full upper jaw denture usually has a smooth surface of the side which faces the tongue. This smooth surface can cause lifelong irritation to the denture wearer because the tongue is on constant contact with the denture surface and generates a nerve signal indicating the presence of a foreign body in the mouth. This produces an unpleasant sensation for the denture wearer which often causes nausea. The denture surface facing the tongue has a surface texture which is the same as that on the side of the denture which is pressed against the roof of the mouth. The unpleasant sensation does not then occur. ADVANTAGE - The time required to become accustomed to the denture is reduced
