Title: Complex measurement system for ecg - has control unit giving all complexes same max. value
Inventor: BLEICHER WILFRIED JUERGEN DIPL
IPC: A61B5/04
Filed: 1978-04-04
Abstract: The system increases the accuracy of measurement of the duration and temporary occurrence of the QRS complex in electrocardiograms or other signal complexes occurring quasi-periodically. The signal is so processed (A) that a further signal A+ is produced. The maximum amplitude of each complex of signal A+ assumes, after passing through a control unit, a standard value i.e. so that the maximum amplitudes of all complexes are equal. In addition or alternatively to this the complexes are so processed that their initial and final flanks are steeper. The processed complexes have for their duration fewer and shorter surges than the unprocessed ones.

Title: Electrostatic dust precipitator - uses rotary collecting electrode cooperating with stationary scraper assembly inside electrode
Inventor: ISAHAYA FUMIO
IPC: B03C3/14
Filed: 1978-07-13
Abstract: The dust precipitating unit has an improved dust removal system, and consists of rotary collecting electrode (31) which is mounted in inclined position and supported by roller assemblies (32). The electrode (31) is kept in slow rotating motion by electric motor (35) driving the electrode via reducing gear (34). Dust laden gas enters the unit through inlet opening (46) and passes the static electricity charged inside towards the outlet opening (47). The electrostatic charge is produced by discharge electrode (40). During its rotation the collecting electrode the inner surface is in constant contact with scaper assembly (43) fitted to scraper head (42). Dust precipitated on the inside of the collecting electrode is mechanically removed and travels partly due to the inclined position of the collecting electrode and partly due to the special shape of the scraper elements towards the inlet end, from where it is transported to, the outside by screw conveyor (44).

Title: Continuous compressive crumpling appts. for fabric rope - comprises perforated tube surrounded by steam jacket
Inventor: KUEHN KLAUS
IPC: D06C23/04
Filed: 1979-08-10
Abstract: A rope of, partic., pile fabric is subjected to a compressive heat-treatment in a straight, or J-shaped tubular stuffer chamber into which the fabric is continuously packed by a stuffer device. The central section of the stuffer tube is perforated, and surrounded by a steam-box, whereby steam can penetrate the fabric to set the random folds produced by the stuffing process. The exit end of the tube is also perforated to promote cooling of the fabric before withdrawal from the upturned end of the tube. The steaming treatment consumes less energy than previous processes using boiling-water immersion followed by cold-water immersion. It is quicker, and allows the use of temps. above 100 deg.C if necessary The fabric emerges almost dry from the tube, and mangling and drying treatments are not required.

Title: Control circuit for vehicle courtesy light - provides time delay for lamp extinction after doors are closed
Inventor: KREISLER KLAUS
IPC: B60Q9/00
Filed: 1980-02-25
Abstract: The control circuit is used to divert the lamp current from the controlling transistor, and also to limit the effects of any failure in the time delay circuit. The control unit (6) comprises a reservoir capacitor (C1), charge and discharge resistors (R1,R2,R3) and switching transistors (T1,T2,T3). The whole circuit is connected between the positive terminal (30) of the vehicle power supply and the door switch (TK). With the selector switch (5) in the normal position (2) closure of the door switch (TK), i.e. by opening a door, connects the lamp (3), and also the capacitor charge circuit (C1,R3) across the supply (30,31,7). The lamp current thus passes only through a routing diode (D2). When the capacitor is charged, the transistors turn on and the lamp current tends to flow through the last stage (T3). When the doors are closed, the lamp draws power from the capacitor until the latter has discharged (R1,R2) to the point where the transistors turn off, typically 12 seconds after door closure. Charging time is approximately 1 second.

Abstract: The brake is used for direct conversion of wind or mechanical energy into heat energy. It comprises a permanent magnet variable eddy current disc brake with an efficiency which increases in proportion to the rotation rate, the conductive brake disc positioned in the gap between facing permanent magnetic poles. The braking regulation is provided by moving the latter to alter the radius at which the braking force acts on the disc and/or by adjusting the distance between the poles and/or by rotating the poles relative to the direction of movement of the disc. The brake exhibits a high reliability with a long working life and has a high efficiency with the braking regulation effected without requiring outside energy.
