Patent DE-4407345-A1 (DE)
Inventor: BROEDEL AXEL DR
IPC: G05D11/13
Filed: 1994-03-05
Abstract: The novelty is that a process and assembly measures the presence of a gas medium (1) by means of a chemical sensor (12) operating in a nominal range and generating a detection signal (14). The chemical sensor (12) is exposed to a mixture of the gas sample diluted with another gas (2) as required. The dilution ratio of the gases is constantly regulated. The dilution ratio is determined by measuring the concentration of a given substance (02) within the mixed gases. The oxygen in the dilution gas (2) is present at a known constant concentration, and its presence is measured in the sample gas flow (1) and the gas mixture (3).
Patent DE-4408877-A1 (DE)
Inventor: BOEHM THOMAS
IPC: G01M3/20
Filed: 1994-03-16
Abstract: The invention relates to a process for operating a test gas leak indicator (1) with a gas inlet (2) and a test gas-sensitive detector (4), in which all or part of a stream of gas containing the test gas reaching the inlet (2) is taken to the detector (4) in the event of a leak; in order to improve the sensitivity of the leakage detection, it is proposed that the stream of gas be preferably periodically modulated and the signal from the test gas detector (4) be processed in synchronism with the modulation of the gas flow.

Title: Process for reprocessing recyclable mixtures of plastics waste
IPC: B29B17/02
Filed: 1994-03-31
Abstract: The invention relates to a process for reprocessing mixtures of plastics waste. The aim of the invention is the separation of plastics components from mixtures of plastics waste. The components of the various types of plastics waste are characterised, inter alia, by their behaviour at low temperatures under mechanical loading. By subjecting them to mechanical vibrations, products of the most diverse types of plastics burst at low temperatures. Accordingly, the separation of a component from a mixture of plastics waste is performed by the component being broken down by bursting with defined temperature and mechanical-loading parameters. The broken-down plastics component is separated from the remaining waste.   Recycling of plastics.

Title: Ignition device (starting device) for a high-pressure lamp
Inventor: BRAUN WERNER
IPC: H05B41/04
Filed: 1994-08-02
Abstract: A radio-frequency oscillator (265 kHz) controls a transistor (V10) which switches a current through the primary winding of an intermediate transformer (TR1). Its secondary winding feeds an intermediate circuit with a rectifier (V8, V9) in a voltage doubler circuit. By means of the rectified voltage, a charging capacitor (C8) is charged which is in series with the primary winding of a high-voltage transformer (TR2) and a switching spark gap (SF). When the voltage of the charging capacitor (C8) reaches the breakdown voltage of the switching spark gap (SF) of approximately 2 kV, the latter short-circuits the capacitor (C8) via the primary winding of the high-voltage transformer (TR2), as a result of which, in the secondary winding of the latter, the high voltage of approximately 19 kV, required for igniting a high-pressure lamp, is induced at a frequency of approximately 50 to 60 Hz. The invention is used in ignition devices for high-pressure lamps. <IMAGE>

Title: Process for building by sectors a slit trench foundation wall
Inventor: ROSENSTOCK WINFRIED
IPC: E02D5/18
Filed: 1984-11-07
Abstract: Two holes (9, 10) are dug into the ground, at a certain interval from each other, and are as wide as the future slit trench foundation wall and have the definitive depth of said wall and are filled during their formation with a thixotropic liquid, so that the final interval separating the holes is suppressed and is also filled with the thixotropic liquid, and so that the whole segment is then filled with concrete from the bottom to the top while the thixotropic liquid is discharged. The invention provides during the construction of the slit trench foundation wall into a rocky underground, to dig into the ground between the two holes (9, 10) a drilling hole (16) provided on its length with an explosive charge (17); at the lower end of the two holes a pressure effect is produced during a short time lapse, which pressure effect enables to take out temporarily the thixotropic liquid from the holes and to discharge it upwardly, as well as to fire the first explosive charge (17) during the discharge of the thixotropic liquid. The discharge may be carried out by means of a second explosive charge (18) placed at the bottom of each of the two holes, the second explosive charges (18) being fired a little before the first explosive charge (17) is fired. It would also be possible to cause a pressure air thrust at the bottom of both holes (9, 10) a little before the firing of the first explosive charge (17).

Patent WO-9104467-A1 (WO)
Inventor: DREYER VOLKER
IPC: G01F23/00
Filed: 1990-09-19
Abstract: The device comprises at least two oscillating rods which are attached, at a given distance apart, to a membrane, the edge of which is connected to a screwed piece. On the side of the membrane remote from the oscillating rods, a tensioning screw is ridigly connected to the membrane so that the tensioning screw and the membrane adopt a position relative to each other in which the axes of symmetry coincide. The tensioning screw is surrounded by a pile of annular piezoelectric elements, electrodes and insulating rings. This pile consitutes the exciting and receiving transducer of the device. The transducer is clamped and fastened between the membrane and a hexagonal nut. The pile thus rests on pressure points arranged between the membrane and a metal ring which terminates the pile. The clamping force is chosen so that the membrane is simultaneously pretensioned in a concave shape. The exciting transducer causes the oscillating rods to oscillate at their natural resonance frequency in opposite directions and perpendicular to their longitudinal axes. Any change in the oscillating behaviour of the oscillating rods is detected by the receiving transducer and used to determined and/or monitor the predetermined volume. It is thus possible to exploit both the frequency and the amplitude of oscillation of the oscillating rods.
