Inventor: PETRICK PAUL DR
IPC: H01G4/32
Filed: 1989-09-07
Abstract: Capacitors made from metallised plastic film are contacted with external contacts of sprayed metals, to which connectors or brackets are conductivity attached. The sprayed layers use alloys of Al with Mg, Zn or Si or combinations of these which have a low m.pt. i.e. lower than pure Al, and a low heat conductivity. Alloy compsns. claimed are Al combined with 5, 9 or 10% Mg, 10% Zn, 12% Si, 9% Si, and 3.5% Cu, 12 % Si, and 3% Cu. Also claimed is the addn. of a further layer with a still lower heat conductivity on the Al-alloy layer. USE/ADVANTAGE - The lower m.pt. reduces the damage done to the plastic film and the contact region during the metal spraying process. This is capable of increasing the capacitor yield. The lower heat conductivity reduces the damage done to the metallised film during the soldering process. The process is used esp. for chip capacitors, but also for capacitors with wire-connections.

Title: Blowing dust from scoured small area of air filter - by mobile air-jet bar in narrow hoppers moved in synchronism below filters
Inventor: KOESTER MANFRED DIPL ING
IPC: B01D46/42
Filed: 1989-09-27
Abstract: During ascent from an inlet to a head outlet dust-laden air is filtered by passing through a casing with rows of independent filter elements, e.g. suspended fabric bags. Movable transversely over the upper end of the filter casing is an apertured bar whose multiple jets direct streams of compressed air downwards into the filter elements, detaching dust accumulated on the exteriors. On the dirty approach side to the filters are one or more hoppers each coupled at its base to a hose leading to a base dust  collector. The hoppers are moved in synchronism with the aperatured bar, and are of narrow width, sufficient to collect dust blown from the particular row of filter elements located immediately above the hopper mouths. Hoppers and apertured bar are both advanced by a linear pneumatic drive controlled by proximity sensors. ADVANTAGE - Since prepondant part of filter unit operates normally during the intermittent cleaning, the duplicate filter unit commonly needed at such times is unnecessary.

Patent DE-4000215-A1 (DE)
Inventor: PRIEM CURTIS
IPC: G06T11/00
Filed: 1990-01-05
Abstract: An apparatus and method for using a test window to improve the efficient of clipping (39) and inter-coordinate images which are to be displayed by a graphic display subsystem. A test window (45) is defined (TEST X, TEST Y) which surrounds a window (X Clip, Y Clip) (the clip window) within which it is desired to render graphical images. Objects are then tested (47) to see if their vertices (X0 - X3, Y0 - Y3) are outside the test window. The utilization of this test window allows for a performance optimization to be made between processing of a clipped object by a hardware based graphics subsystem which incorporates the present invention or by graphics software executed by a general purpose CPU which also interfaces to the graphics display. By properly defining the test window size relative to the clip window, objects which fall totally within the test window, will be rendered faster by the graphics subsystem rather than deferring the object to graphics software. Objects with vertices that fall outside the test window would be deferred to graphics software to render. <IMAGE>

Patent DE-4031858-A1 (DE)
Inventor: SCHAUTZGY ACHIM DIPL ING
IPC: A01B39/16
Filed: 1990-10-08
Abstract: In an agricultural machine (1) with a swivelling supporting arm (3) which is provided with a soil cultivating tool (5) and with a feeler (11) and on which there acts an adjusting piston (16) of a lifting cylinder (15), pressure medium can be fed to the latter in a controlled manner by means of a control device (31). The control device (31) consists of a 4/3-way valve (38) inserted into the pressure-medium feedlines (41, 42) and of switching elements (46, 47) which can be influenced by the feeler (11) and the supporting arm (3). To allow mechanical actuation of the adjusting member (39) of the directional control valve (38) from one side as a function of the respective swivelling movement of the feeler (11) upon swivelling in, the feeler is connected positively to the adjusting member (39) via a Bowden cable (51), such that the adjusting member can be adjusted in proportion to the respective adjustment path of the feeler (11). By virtue of this configuration, it is possible not only to control the swivelling movement of the supporting arm (3) exactly and hold it continuously in a defined position, but high mechanical stresses on the swivelling arm are also reliably avoided since the directional control valve (38) is opened slowly as a function of the swivelling movement of the feeler (11) and the pressure in the lifting cylinder is thus built up continuously. <IMAGE>

Title: Film production in multiroller calender - using cascade system of rollers with wedge in one gap to blend, fuse, dispensed, melt, degas and form material in one single pass
Inventor: REHER ERNST-OTTO PROF DR SC TE
IPC: B29C43/24
Filed: 1991-03-02
Abstract: In the production of films on multi-roller calenders (with 3 or more and primarily 4 to 5 rollers) several individual stages are combined together; the first gap is designed geometrically, thermally and kinematically to homogenise and melt the material, and its processing into film is made in the next gap by using wedge-shaped tools. Premixed material or powder/granules are fed into a roller and repeatedly passed round it; the roller can be heated. A specific portion of the homogenised material is next taken off and passed over roller into the gap between rollers e.g. for repeated similar treatment and, in the case of a 5-roller calender, again in the next gap. This produces a very uniform material. ADVANTAGE - The method utilises a conventional calender but combines together a number of stages
