Title: Varnishing of instrument panel of motor vehicle - by using mask with air flow from under mask edges
IPC: B05B12/20
Filed: 1989-06-16
Abstract: The instrument panel of a motor vehicle is sprayed with varnish to produce a grained finish on the surface in defined areas which are separated in a clear cut manner from the remaining areas. This effect is achieved by covering the areas which are not to be varnished with a mask (2). The mask (2) is so shaped that there is  a small gap (4) between its edge and the instrument panel surface.  A gas, such as air, is blown into the mask so that it flows out through the gap (4).  The exposed areas are then sprayed with  varnish from a spray gun (5).  The outflow of air from the mask then ensures that only required areas are varnished with a clearly defined boundary. USE - Varnishing of car interiors.

Title: Signal evaluation or image reproduction - generates sensor or video signal from difference of two frequency bands, or from object colour
Inventor: LANG JOHANN
IPC: G01S3/781
Filed: 1989-07-14
Abstract: The evaluation or image reproduction is carried out by multi-spectral image processing, detected in different wavelength regions and process. From the difference of output received in several frequency bands, or from the object signal in visible systems, a sensor signal or a video image is generated, representing the gradient of the spectral intensity course. The process is carried out by forming the ratio, or the difference of the radiation output measured in several frequency bands. Alternatively a continuous differentiation of the impinging output according to the wavelength, or the frequency, is used. USE/ADVANTAGE - Optical location system, with reliable differentiation between sunshine reflecting radiators and hot punct form radiators.
Patent DE-3925913-A1 (DE)
Inventor: LEHMANN MANFRED PROF DR
IPC: G06K15/10
Filed: 1989-08-04
Abstract: The invention relates to a process for driving printing elements of a dot matrix printer in which the matrix dots to be printed are to be thinned out without any thin lines, in particular steeply inclined thin lines, being lost. To this end, the columns of the matrix are considered to be arranged next to each other in pairs, and before the matrix dots in each line (Z) of the matrix are thinned out, a matrix dot is placed before or after a matrix dot used initially to create the character, so that both matrix dots belonging to a pair of columns (SP1, SP5) are covered by a line (Z). During the subsequent thinning out, the lines are printed sufficiently well and clearly. The process is intended for use in dot matrix printers.

Title: Device for holding motor vehicle door open - uses helical coil spring to grip door stay when rotated by cable at door open position
Inventor: KLUETUNG BERND ALFRED DIPL ING
IPC: E05C17/20
Filed: 1989-11-08
Abstract: The door of a motor vehicle is provided with a device to hold it in the open position. The device consists of a rod with one end attached to the door.

Patent DE-3940602-A1 (DE)
Inventor: COLFORD TERRY
IPC: F16F15/12
Filed: 1989-12-08
Abstract: A torsional vibration damper in which a fly-ring (3) is fixed on the outer circumference of a hub ring (1) of metallic material by a separately manufactured spring ring (4) of rubber. On the side facing the spring ring (4), the hub ring (1) is provided with a firmly adhering continuous coating (5) of thermosetting plastic. The ratio of the mean radial thickness (A) of the coating and of the mean radial thickness (B) of the spring ring (4) is from 0.25 to 3. The thermal expansion of the coating (5) which occurs during use brings about a radial prestress of corresponding size in the spring ring (4). As a result, the spring ring always has largely corresponding spring properties irrespective of the operating temperature.
Patent DE-4001614-A1 (DE)
Inventor: BUCHS WILLY
IPC: G01G7/04
Filed: 1990-01-20
Abstract: A compensation balance (10) has at least one acceleration sensor (24, 25) arranged on a mobile part (14) of the balance (10), which sends a signal to a correction signal processing arrangement (50).

Title: Twisting machine process - which utilises yarn detection device to stop the machine for piecing up before reel changeover
Inventor: SCHLAGENHAFT WALTER
IPC: D01H15/007
Filed: 1990-04-20
Abstract: A process to piece the ends from assembly wound spools on an uptwister. The two-fold yarn is under surveillance as it leaves the spool, so that the machine is stopped before the cone empties. The single yarns are spliced to the new spool yarn, so that it follows through the hollow spindle to the twister. Pref. the system also applies to two-for-one folding. The amt. of yarn (V1) on the cone (2) may be assessed by a photo-electric device (6) or a measure of the yarn may be taken by the measuring device (7), so that wind-off is stopped near the end, leaving yarn (G) in the hollow spindle (4). The yarn is pieced up to the new spool either before or after this is placed onto the spindle. The joints are offset, so that both are not in the same position when twisted.  The piecing may be made by using adhesive or by splicing, and afterwards it is necessary to draw the yarn into a tensioned position, before re-starting the machine. ADVANTAGE - The piecing on each yarn results in a continuously twisted yarn with no faults.
