Patent DE-4409970-A1 (DE)
Inventor: BIES PETER DIPL ING
IPC: B01D29/11
Filed: 1994-03-23
Abstract: The invention concerns a filter element having a support member (11) which comprises a support tube (12) which can be brought into abutment with a filter mat (14) and which is provided with apertures (16) for the passage of a filtered medium. The apertures (16) are formed by the axial spaces between individual rings (18) of the support member (11) which are supported by support walls (20) dividing the interior of the support tube (12) into individual chambers (22). By virtue of the fact that the support member (11) is rendered compression-stiff such that it exclusively supports the filter mat (14) when the medium flows therethrough, the respective support wall (20) is directly connected to the rings (18) for this purpose and each ring (18) with its closed annular shape surrounds the support walls (20) on the peripheral side from the exterior, the filtration capacity of filter elements can be improved and the weight and cost simultaneously reduced owing to the highly stable and compression-stiff support member.

Title: Connector for coupling test and measuring devices to main distributor
Inventor: HALATSCHEFF HARRY
IPC: G01R1/04
Filed: 1994-04-07
Abstract: Eight contact strips(Ks) respectively insulated from each other, are fitted on each side, arranged in pairs lying opposite. Which at the side facing the main distributor, have contact surfaces (Kf) projecting over the carrier material. SO that the opposite lying contact strips (Ksa + Ksa'; Ksb + Ksb') always respectively make contact connection with each other. The connection contacts in their dimensions and in their spacing to each other, coincide with the dimensions of the contact sets of the isolating block. The distance between the opposite contact surfaces (Kf) of all the connection contacts are dimensioned such that in the plugged position of each LSA1 contact with the operating elements (FktE1) provided with the isolating plugs, lies respectively between the two contact surfaces (KKf) of the connecting contacts of the test probe allocated to it.
Patent DE-4420024-A1 (DE)
Inventor: UEBBING REINHOLD DR
IPC: H01L21/20
Filed: 1994-06-09
Abstract: Semifinished products designed as composite bodies for electronic or opto-electronic semiconductor components are known. The composite bodies are made of a disk-shaped, transparent quartz glass substrate and of a slice made of a semiconductor material. The directly bonded surfaces of the quartz glass substrate and slice are polished before being mutually bonded. In order to create a semifinished product that resists temperatures above 900  DEG C, such as those used to produce semiconductor circuits in industrially feasible times, without raising fears of a substantial reduction of the adhesive forces, chipping of the slices away from each other or an undesirable deformation of the composite body, the substrate quartz glass is a synthetic quartz glass with at least 10<14.0> poise viscosity at 950 DEG C which does not fall below 10<12> poise at 1050  DEG C. The synthetic quartz glass contains maximum 1 ppm alkali elements and maximum 1 ppm metallic impurities of the elements iron, nickel, copper, chromium and/or transition metals. At least one of the polished surfaces has a roughness depth Rq not higher than 2 nm.

Patent DE-4421728-A1 (DE)
Title: Audio signal system for stamping machine or punching press
Inventor: MERKLE PAUL
IPC: B21D55/00
Filed: 1994-06-21
Abstract: The audio signalling system has an audio signal unit (23) which is only subjected to the flow of m-positive DC current. The additional circuit consists of a flip-flop (18) and an AND logic gate (20), a relay (21) with a self holding unit, a transistor (24), a diode (25), a foot switch (26), a switch (27) and a diode (29). When the foot switch is closed, the relay coil (22) is not subjected to a DC current due to the operation of a pressure spring (28). When a workpiece is not discharged, the AND gate has a logic HIGH output, thus triggering the transistor to trip the relay by supplying a high relay coil current, thus interrupting the current path via the foot-switch, and closing a current path (b,c) to the audio signal unit, so that an m-positive potential supplies current to both the relay coil and the signal unit.
Patent DE-4422879-A1 (DE)
Title: Admission pressure valve
Inventor: SEEGERS HANNS DIPL ING
IPC: F16D48/02
Filed: 1994-06-30
Abstract: The invention relates to a hydraulic admission pressure valve with a sealing seat for the purpose of achieving an admission pressure at a release bearing of a vehicle clutch. The object of the invention is to provide an admission pressure valve by means of which effective air evacuation from the system can be achieved during initial filling and which furthermore provides continuous damping of pressure fluctuations during operation of the vehicle caused by axial vibrations of the clutch and/or of the crank shaft. For this purpose, the invention provides an admission pressure valve (1) which has a sealing seat (24), in which the tappet (19) belonging to the sealing seat remains open during the initial filling of the system and the components which form the sealing seat (24) influence the flow of hydraulic fluid as a function of the direction of flow. <IMAGE>

Patent DE-4424723-A1 (DE)
Title: Producing pull-off specimen strips from photographic film strips
Inventor: TAKAHASHI HIROSHI
IPC: G02B13/24
Filed: 1994-07-13
Abstract: The method involves using film strips with a number of copying originals. Order numbers are illuminated in a spatial relationship to the originals to form images on the specimen strips (5). A lens (2) is used for optical imaging off-centrally on a part of a copying material strip (5) at least twice the width of the desired pull-off strip. During subsequent passes images are formed on further, unilluminated parts (5b) of the copying material strip, which is subsequently divided into two or more strips. A mask can be used and successive passes of the material through the illumination device can be in the same direction without intermediate respooling.

Title: Device for filtering gases
Inventor: REINHARDT ERICH KARL
IPC: B01D46/24
Filed: 1986-05-30
Abstract: The device for filtering gases comprises a perforated plate (1) which devides a receptacle into two parts, from which plate filter elements (3) are suspending by an annular flange arranged on their upper edge, whereby the gas to be filtered flows from the part located below the perforated plate, to the upper part, passing, from the outside to the inside, through the filter elements in the form of a pot or candle. To ensure a more reliable seal between the filter elements and the perforated plate, while enabling safe dismantling despite local pressure picks, it is proposed that weights (5) with through passages (6) connecting the inside of the filters with the upper part are placed on the filter elements (3).
