Title: Sequence director for computer-controlled belt conveyor system - uses by=pass tracks for routing articles to and from connecting track without negotiating parallel waiting tracks
Inventor: PHANCON TAN DIPL ING
IPC: B65G47/51
Filed: 1989-10-26
Abstract: In the interests of space-saving and high throughput, the system provides entry and exit gps. (3,13) of waiting tracks (4-6,14-16) entered and left via individual junctions (26-38) and a connecting track (25).  The junctions are switched automatically by a computer in response to signals from readers (39-50) of sequence and destination data encoded on the articles in transit. Space is provided on each waiting track (e.g. 6) for two or more waiting positions (11,12).  A bypass track (23,24) is assigned to each gp. (3,13) and the circuit is completed by a return track (51) with another reader (54) at its entrance junction (53). USE/ADVANTAGE - In e.g. mass prodn. of motor vehicles.  Emergency operation can be maintained by instructions from e.g. hand-held terminals even in event of failure of switching control computer.
Patent DE-3940217-A1 (DE)
Inventor: KASAHARA NOBUO
IPC: G03G15/16
Filed: 1989-12-05
Abstract: An electrographic image forming apparatus comprises means for forming a latent image on a carrier in either inverted or non-inverted form; typically, the apparatus can be a printer using a laser to image drum 105, or a copier where the laser is digitally controlled in response to scanning of an original G. After developing at station 106, the toned images can be transferred directly to one side of a sheet S passing between the drum 105 and an intermediate carrier such as belt 107 or can be temporarily transferred to belt 107 for use on the other side of the sheet S. The apparatus can be used in a two-pass mode with the sheet being re-circulated through guides SG' and SG'', and/or with developed images being supplied simultaneously to both sides of the sheets. Multi-colour effects can also be obtained, especially with the arrangement of Fig. 26, involving a belt (1) as the image carrier, and four developing stations (7, 9, 11, 13). When images are formed simultaneously on both sides of a sheet S, the sheet need only be passed through fixing section 117 once. <IMAGE>

Patent DE-3943705-A1 (DE)
Title: Pressure charged engine exhaust braking system - increases power supplied to pressure charger to augment braking effect.
Inventor: RICHTER HORST
IPC: F02M26/71
Filed: 1989-10-24
Abstract: When braking the vehicle, the operating gas is compressed and at least partly extracted from the working chambers. To augment the braking effect, the degree of pressure charging is increased by supplying additional power to the pressure charger and thus raising its speed of rotation. In the case of an exhaust turbocharger, this can be done by reducing the cross-section of the turbine inlet by at least 50%. The flow of exhaust gas upstream of the turbine can also be throttled to increase exhaust gas backpressure.In the case of a mechanically driven charger, accumulated exhaust gas can be fed to the charge air delivered by it. ADVANTAGE - No need for exhaust gas cooling.

Patent DE-4015017-A1 (DE)
Inventor: CISEWSKI WERNER
IPC: B05C11/10
Filed: 1990-05-10
Abstract: 2.1 When applying a coating material of this kind, hitherto the level of the foam upstream of the coating device has been observed visually and the gap width between coating device and carrier web has been set manually. This only permits an imperfect compensation of thickness fluctuations of the uncoated carrier web. An excessively fluctuating basis weight of the coating constitutes a quality defect and is uneconomical. 2.2 In the process according to the invention, the level of foam upstream of the coating device is measured at short intervals of time by means of a contactless removal measuring process. The measuring signal which is evaluated for plausibility is either provided via a controller to a control device with which the gap width is automatically controlled or the throughput of the mixing apparatus for manufacturing the foamed coating material is controlled. As a result, the thickness of the coating is considerably more uniform. 2.3 The process is used when coating floor coverings and wallpapers. 3. There is no figure.

Title: Pneumatic central locking and antitheft system for motor vehicle - has pressure generator, pressure line, and regulating element for locking and protection per locking place with pressure sensor with control unit
Inventor: RATHMANN KLAUS
IPC: E05B77/50
Filed: 1990-12-12
Abstract: The adjusting elements for the central locking (ZV) and the theft protection (DS) are controlled over the same pressure line system (2).

Inventor: EGGL WILFRIED DIPL ING
IPC: G01N33/487
Filed: 1991-04-24
Abstract: 2.1. A known device for photometric measurement of blood or blood plasma has a cuvette holder which is provided with one or more Küvette receptacles into which in each case one cuvette filled with an appropriate sample can be inserted from above. It has been necessary to date for the corresponding cuvette to be withdrawn upwards from the cuvette receptacle upon termination of the photometric measurement. During this time, no photometric measurement can be performed. It is therefore the object of the invention to shorten the temporal sequence of a photometric measurement. 2.2. For this purpose, the cuvette receptacle (3) is provided on its underside with a through opening which can end in a shaft (6). Furthermore, the cuvette receptacle (3) has a leaf spring (8) by means of which the sample to be measured can be locked in the cuvette receptacle (3). 2.3. The design permits a cuvette which is to be freshly inserted into the cuvette receptacle to be used to eject downwards the cuvette for which measurement has been concluded. A removal upwards is no longer required, and so the removal time is eliminated and the temporal photometric measurement is substantially shortened. <IMAGE>

Title: Pneumatic sheet checking system for printing machine - has vacuum pump and suction system for detecting sheet presence on feed cylinder via anemometer and electronic evaluation
Inventor: BOETTGER JOHANNES DIPL ING
IPC: B41F33/14

Abstract: A pneumatic sheet checking device for a printing machine employs an air suction system powered by a vacuum pump (30) for establishing the presence of a sheet (28) on the sheet feed cylinder (25) prior to the commencement of the printing cycle. A suction pipe (29) connected to a suction orifice (26) on the feed cylinder (25) contains an anemometer assembly (X), whereby the absence of a sheet prompts an increased airflow detected electrically as a result of a resistance change in a preheated wire. The resultant signal is electronically processed to initiate a machine stop. USE/ADVANTAGE - Simply constructed, sensitive and reliable system capable of high speed operation at all machine speeds. Can be set for any type of print routine, sheet format and print material.
