Title: Responsive control of pipework pressurisation, pressure fluctuation and uneven delivery in viscous material dispensing systems
Inventor: WOELFLE MANFRED
IPC: G05D16/20
Filed: 1996-11-29
Abstract: This method extracts and delivers viscous material e.g. a plastic, using an air-driven piston pump. This pumps the material from a vessel via a line to a dispensing unit. In the new arrangement, the pressure of the material at the dispensing unit is regulated to a desired value. For this purpose its pressure is measured. On deviation from the desired value, the air pressure driving the piston pump is controlled accordingly. Also claimed is the corresponding equipment in which a servo controller (34) varies air pressure supplied to the motor (26) driving the pump (24). The actual value of material pressure is measured by a sensor (36) for this purpose, at the delivery unit (30). Preferably the piston pump is a double acting unit, and is especially a drum or barrel extraction pump.

Patent DE-19705576-A1 (DE)
Inventor: DOHNAL DIETER DR ING
IPC: H01H9/00
Filed: 1997-02-14
Abstract: The invention relates to a position signalling layout for a motor drive which also serves to activate an on-load tap changer, an off-circuit tap changer or a plunger core coil. Position signalling devices of this kind detect the position at a given time of the on-load tap changer or similar and transmit this information in the form of an electric signal. According to the invention, the device consists essentially of a board on which there are fixed signalling contacts and a pivoted cam disc which connects said fixed contacts electrically and links them to a terminal lead via a spring operated switch, activating the spring operated switch by means of its front cam contour.

Patent DE-19731638-A1 (DE)
Title: Procedure for making frictional spot-welded joints using rubbing pin
Inventor: SCHAAF ANDREAS
IPC: B23K20/12
Filed: 1997-07-23
Abstract: A procedure for making spot-type weld joints using a rubbing pin has a rotating pin (3), lying from the opposite side of the joint zone, penetrating into the one of the workpieces to be joined without piercing it. In the region of the joint zone, the workpieces are pressed together by the pressure of the pin and an axial fixing of the opposite piece. The rubbing and the pressure in the region of the joint zone effect a temperature increase. The pin is withdrawn again after the welding process or remains as a unit on the joint. For jointing with the pins remaining, the drive unit (8) is stopped shortly before the end of the welding process.
Patent DE-19732303-A1 (DE)
Title: Car door lock blocking against unwanted opening
Inventor: MEYER DIETER
IPC: E05B77/06
Filed: 1997-07-26
Abstract: In normal conditions, i.e. without acceleration, the lever (9) is spaced from the shaft (4) until acceleration swings the lever onto the shaft by supplementary force (14) thus preventing the shaft from movement. The contact faces (15,16) of lever and shaft make up a forcible or positive connection between the shaft and lever, possibly using toothing on lever or shaft for this purpose. The positive connection can also be provided by a latching device (17) and the re-set spring (12) fitted to the lever is of the leg type. Lateral impact (18) on the door lock, e.g. in accidents, applies moment to the lever which thus swings against its spring towards the shaft, there to latch home to arrest any shaft movement (19) despite inertia, securely guarding against forcible opening. Otherwise the lever is retracted by its spring clear of the shaft so the outside door handle (3) can be turned as required.

Title: Method of monitoring a defined amplitude threshold value for a.c. voltage input signals, esp. for electronic controllers
Inventor: CULCA HOREA-STEFAN
IPC: H02H3/24
Filed: 1997-11-04
Abstract: The method involves eliminating negative half waves from the input signal, reducing the remaining positive half waves' voltage level, testing whether the result is above or below the threshold and generating a corresp. binary signal (S1). Reference signal null crossings are simultaneously monitored and a corresp. second binary signal (S2) generated.   A third signal (S3) is generated by delaying the second signal so state changes occur at positive input signal half wave maxima.  A fourth binary signal (S4) generated by evaluating the first signal at the time of the third signal's state change is used to decide whether the positive half wave value is above or below the threshold (L). Independent claims are also included for circuits which implement the method.

Title: Harmonics compensation method in electric supply network
Inventor: BREDTMANN RUEDIGER
IPC: H02J3/01
Filed: 1998-04-27
Abstract: The method involves filtering out a basic oscillation from load currents (IfI1, IfI2, IfI3) in a first (A) and a second (B) cascade filter, and then filtering harmonics of any arbitrary order as discreet harmonics (I approx. af5, I approx. bf5, I approx. af7, I approx. bf7). The produced values are used for controlling an active harmonics filter, to produce a compensation current. The output values are combined to form a spatial vector, and three nominal currents (Ifa, Ifb, Ifc) for a pulsed current converter are formed by means of an inverse Clarke transformation (20).- DETAILED DESCRIPTION - The method involves filtering and suppressing a basic oscillation by means of a cascade filter (A) from load currents (IfI1, IfI2, IfI3), and then filtering harmonics of 5th, 7th, and any arbitrary further order as discrete harmonics (I approx. af5, I approx. bf5, I approx. af7, I approx. bf7) with original phase and amplitude, from a signal with high harmonics portion. The, thereby produced values are used for controlling an active harmonics filter, to produce a compensation current. The basic oscillation is filtered and suppressed by means of a further cascade filter (B) similar to the first filter.   Harmonics of 5th, 7th, and any arbitrary further order are then filtered as discreet harmonics (I approx. af5', I approx.bf5', I approx. af7', I approx. bf7') with original phase and amplitude. The harmonics of the load current are compared with nominal values in a coupled compatibility level regulator (C), and the outputs (Ibeg5', Ibeg7') of the compatibility level regulator are multiplied in multipliers (16 to 19) with the outputs of the first cascade filter, to form a spatial vector (I approx. af, I approx. bf). Three nominal currents (Ifa, Ifb, Ifc) for a pulsed current converter are formed from the spatial vector by means of an inverse Clarke transformation (20), for producing the correction currents of the three supply phases
