Patent DE-2842297-A1 (DE)
Title: Measurement of extinction valves for gas samples - using Michelson cell with split laser beam, one beam passing through sample and back to detector
Inventor: NIEMANN HANS-JOACHIM DIPL CHEM
IPC: G01N21/45
Filed: 1978-09-28
Abstract: The extinction value of gases for wavelength dependent determsn. is measured by an interferometer Michelson-type arrangement. This has a light beam from a single source divided into two coherent beams and then recombined to measure the optical interference. The two beams have the same intensity I1, 22 but are subjected to a wavelength shift of a half or some integer multiple. The sample is introduced into the path of one of the beams. The resulting intensity IM of the two interference beams is measured by a detector. The two beam intensities are measured simultaneously and the resulting function E determined from E = -log (1- /IM/I1). The system is designed for low absorptions such that measurement errors practically do not influence the values determined.

Title: Traffic flow information system - has on-board units communicating with road side stations providing traffic condition information
Inventor: PILATZKI BERND
IPC: G08G1/09
Filed: 1978-11-20
Abstract: A traffic flow and information system for read users utilises an on board transmitter-receiver operating together with road side units. The system is intended partic. for use with motorway systems. The motorway routes are assigned different codings and these are transmitted by the driver to be collated by roadside receiver-transmitter units. Traffic situations are assessed along the route and information relating to traffic speed accidents, delays due to roadworks etc. are transmitted. Each vehicle is provided with a display and dark entry system that allows codings to be entered. Speed is interpreted on the basis of several selected ranges. A variety of road conditions e.g. ice, fog, snow ahead may be signalled to the vehicle driver.

Title: Wind powered catamaran with improved gliding - has flat-bottom extensions outboard of hulls, angled up to stay clear of water as long as both hulls are immersed
Inventor: WEGENER YORCK
IPC: B63B1/12
Filed: 1979-02-27
Abstract: The wind-powered catamaran is conventional in concept. However, each of the hulls has a flat-bottomed extension (8, 9) outboard, pref. of full length, inclined to the catamaran waterline (7) and not immersed when it is upright. The inclination is 5 - 30 deg., pref. 10 - 15 deg. and should be such that the extensions do not become immersed as long as the opposite main hull is immersed. The main hull immersed surface (5, 6) also flat-bottomed, may be aligned with their extension surface or angled to it, parallel with the waterline. The extensions may have centre boards (10), perpendicular to them.

Title: Measuring IC engine running unevenness - using accelerometer or speed transducer with output filter, rectifier and integrator
Inventor: MAUSNER EBERHARD DIPL ING
IPC: G01P15/08
Filed: 1979-03-30
Abstract: The device is for measurement of unevenness in the running of an IC engine and generation of a corresp. measurement signal. It gives measurement results independent of engine revolution rate and is simple is design. Disturbance effects not related to uneven running are eliminated from the output signal. The measurement circuit contains a filter whose output feeds a rectifier via an amplifier. The rectifier drives an intergrator consisting of a low pass filter of large time constant. The centre of the filter pass band may be varied according to the engine revolution rate. Similarly, the amplifier gain may vary with engine speed. The unevenness sensor consists of an accelerometer or speed transducer. The integrator output is proportional to engine roughness.

Title: Circular saw machine boom guide - swings up to limit boom slide in conjunction with control stop
Inventor: STELLWAG HEINZ
IPC: B23D45/02
Filed: 1980-10-28
Abstract: A horizontally protruding boom is mounted on a holding block behind a front workpiece support bench in a circular saw machine. A guide unit on the block, in which the boom slides, swings up from a horizontal boom setting, about an axis vertical to the saw blade operative plane.

Title: Optical guidance system for tool - esp. for micro:welding machine employed to attach conductor wires to semiconductor chips
Inventor: DELFS HANS DIPL PHYS DR
IPC: B23Q17/24
Filed: 1980-12-10
Abstract: Two separate lamps are each provided with a diaphragm contg. a slot, so two light beams with a rectangular cross-section can be projected onto the surface of a workpiece. One beam is aligned in one horizontal coordinate direction (x), whereas the other beam is aligned in a horizontal coordinate direction (Y), which is at 90 deg. w/r/t/ line (X). The point of intersection of the two lines (XY) on the workpiece coincides with a vertical line (Z) along which a tool is moved. The two light beams pref. have different colours so the point of intersection has a mixed colour and is therefore very easy to recognise. The identification of a point on a workpiece is exact, and independent of the thickness of the workpiece, which is e.g. a semiconductor chip.

Title: Electrical capacitor
Inventor: KYSELY ZDENEK DIPL ING
IPC: H01G4/32
Filed: 1981-02-04
Abstract: An electrical capacitor is proposed having a metal or plastic housing (10) into which a capacitor element (11) having connecting wires (13, 14) and having external connecting parts (15, 16) is inserted and is held therein by a potting compound (19). The potting compound (19) partially fills the region between the surface of the capacitor element (11) and the housing (10), while the remaining part of the housing internal space forms an equalising volume for gases and/or compound (24) which melts out of the capacitor element in the event of overheating. The compensating volume (25) is filled with a foam body (18) which, in order to simplify assembly of the capacitor, can be reduced to an initial volume, which is less than the compensating volume (25), by preheating, compression and cooling, before it is inserted into the housing. <IMAGE>
