Patent DE-3843409-A1 (DE)
Title: Colour selection system for text mode (word processing)
Inventor: YOON JU HO
IPC: G09G5/04
Filed: 1988-12-23
Abstract: A text-mode colour selection system is described for a monitor, by means of which the colour tone (hue, shade) of a text reproduction can be selected freely according to the wishes (requirements) of a user, it being possible for the colour tone to be replaced when a user feels disturbed by the colour of a text reproduction. The system comprises a video memory (picture memory), a buffer, a video output section, a restore section, a counter, a NOR gate, invertors, NAND gates, diodes, resistors, and light-emitting diodes. The colour of the text reproduction can be changed as a function of the amount of times a text-mode optional switch (key) has been pressed to assume three different colours, such as for example yellow, green, white on blue.
Patent DE-3903361-A1 (DE)
Title: Vehicle brake with an air supply device
Inventor: SCHEUCHER KLAUS-PETER
IPC: F16D65/847
Filed: 1989-02-04
Abstract: A brake disc (5) attached to a vehicle wheel (1) is provided with a rotationally fixed brake-disc cover (8) adjoining which is an air supply device (9). This has a U-shaped air-inflow duct (10), the latter surrounding an air guide wall (13) projecting into its cross-section. Cooling air can flow into the air-inflow duct (10) in the direction of arrow (c) due to the action of dynamic pressure, via an air inlet opening (11) open in the direction (a) of travel, and, after passing through an air outlet opening (12) can impinge on the brake disc (5). Any coarse lumpy dirt, slush etc. which enters the air-inflow duct (10) via the air inlet opening (11) and sticks to the air-guide wall (13) is dislodged by the vibrations introduced into the vehicle wheel (1) and can fall out via the air-inlet opening (11). <IMAGE>
Patent DE-3907110-A1 (DE)
Title: Heating system for closed rooms
Inventor: DURAS HERBERT DIPL ING
IPC: F24D3/14
Filed: 1989-03-06
Abstract: In low-temperature radiant heating systems, in particular underfloor heating systems operated with hot water, a problem which occurs is that the cold feeling produced by the radiation of the heat from the radiator in the direction of the cold window or external wall is promoted by a rolling air movement which runs from this front downwards in the direction of the room. According to the invention, it is proposed to arrange, in addition to the radiant heating system, water/air heat exchangers which run parallel to and on the window or external wall of the room and to connect these, on the flow side, between heating-water flow and the radiant heating system. A particularly favourable arrangement results when the outlet ducts are connected by air ducts to air inlet ducts on the opposite side of the room and are all located below the level of the floor. The hot air flow rising out of the water/air heat exchangers prevents both the heat radiation from the body in the window direction and the production of a rolling cold-air movement. On cold days, excessively high temperatures of the radiant heating system alone leading to losses of comfort are thus likewise avoided.
Patent DE-3912238-A1 (DE)
Inventor: LEUENBERGER CLAUDE-ERIC
IPC: G04G21/00
Filed: 1989-04-14
Abstract: An electronic watch having an electronic circuit arranged to control at least one function of the watch other than the usual functions of time indication, in which the manipulation of a time-setting rod and/or the position of movable elements of the watch at a given moment define the parameters which, alone or in combination, correspond to access codes which are recognized by the electronic circuit for accessing the advanced features. The present invention proposes to control the advanced features of the watch by means of a single time-setting rod. The time-setting rod of the preferred embodiment detects four parameters for determining an entered access code. These parameters are: (1) the position of the time-setting rod; (2) the rotation of the time-setting rod; (3) the direction of rotation of the time-setting rod; and (4) the rotation velocity of the time-setting rod. These four parameters, taken individually or in combination, can define access codes for the various features of the watch using a single control.

Title: Knitter yarn feed - has cutter to sever the yarn if tension rises which could break the yarn
Inventor: ANASTASIADIS ANASTASIOS
IPC: B65H63/04
Filed: 1990-05-25
Abstract: In the yarn feed path at a knitter, especially a flatbed knitter, between the yarn supply and the knitting point, the yarn is promptly cut if yarn tension builds up at or near the knitting point which could cause a yarn break. The yarn is cut at a point between the supply and knitting point at such a gap from the needles that, after cutting and after the knitter has been stopped, the free yarn end does not reach as far as the needles when the knitter is operated subsequently for a given length. The yarn is cut in its path of travel where, under normal working, it is under a low tension or no tension, between the yarn clamp and the supply bobbin. The yarn tension is monitored, and the yarn cutting action is triggered by the registered yarn tension. ADVANTAGE - The technique reduces knitter down times on a yarn break, and reduces faults in the knitted fabric.

Title: Mechanical force generator - consists of gyroscopic, masses rotating about two axis and fastened to shaft
Inventor: KAUFMANN ECKHARD DR
IPC: F03G3/08
Filed: 1990-05-31
Abstract: The drive generates a mechanical force, which may be used as a propulsive power.  It consists of two or more rigid masses (K1,K2), esp. rotary symmetrical discs, cylinders, etc. fastened to a shaft, and rotated by a drive around an axis (1) in one direction.  The axis is the centroidal axis of the body, esp. the main axis of inertia. The system of two or more masses may be rotated about a second axis (2) in addition to the first rotations.  This may be a centroidal axis  of the system, esp. a main axis of inertia.  This results in a force, directed parallel to axis (2) in a direction, dependant upon the directions of rotation about the axes.

Title: Protection of slot machine against wired coins - comparing stored shutter-activated signals with known value and detecting wires to enable-disable further identification processes
Inventor: PICKHARDT HANS J
IPC: G07F1/04
Filed: 1990-06-27
Abstract: The slot machine protection system consists of a coim-activated shutter (20) which generates a switching signal for later identifying processes. This signal is temporarily held in a delay memory while a wire sensor (24) measures the shutter activation time for comparison with a preset value. The result determines whether the memory signal should be wiped or passed on to an integrated electronic coin identifier. A sensor (35) detects if the coin path is cleared at the correct time or whether a 'wired coin' is being withdrawn. ADVANTAGE - Inexpensive and reliable. Simple construction.

Patent DE-4026087-A1 (DE)
Inventor: ZELENKA THOMAS DR
IPC: H04N1/40
Filed: 1990-08-17
Abstract: The invention relates to a process and circuitry for controlling a laser diode. To compensate for the temperature-depending drop in the light intensity produced by the laser diode (2), the latter is controlled by a voltage generator (3) with an adjustable internal resistance, whereby the rise in the driver current of the laser diode (2) as the temperature rises is set by the internal resistance in such a way that the rise in the light intensity produced determined by the rise in the driver current compensates for the temperature-dependent fall in the light intensity.
