Inventor: GEHM HELMUT DIPL PHYS
IPC: C02F7/00
Filed: 1993-09-11
Abstract: Apparatus for introducing as fine bubbles a pressurised gas which, by means of a ship or another floating device, is moved under water in a stagnant or flowing body of water, comprising a venturi tube arranged in parallel to the direction of motion, in the nozzle throat of which a gas injector opens out and the walls of which, viewed in longitudinal section, are profiled in the manner of an aerofoil which has an angle of attack to the direction of motion and diffuser of which according to the invention is characterised in that it is equipped with a displacement body so that the diffuser orifice angle may be greatly increased without the flow detaching from the inside of the diffuser, and as a consequence of the increased diffuser orifice angle, the tangent at the exterior of the venturi tube forms a large angle of attack to the direction of motion, and in that according to the invention the optimum diffuser orifice angle is adjustable during operation by sliding the displacement body in parallel to the axis of symmetry or to the plane of symmetry. <IMAGE>

Title: Pipe coupling
Inventor: DUNKEL HANS-PETER
IPC: F16L21/00
Filed: 1993-10-01
Abstract: The invention relates to a pipe coupling for the sealed connection of the smooth ends, e.g. the spigot ends of two pipes, which coupling comprises a sealing sleeve formed from an elastic material. The sealing sleeve exhibits axially directed sleeve-ring casing parts which enclose the pipes to be connected, from the end surfaces thereof, over parts of their axial length. The sealing sleeve exhibits, moreover, a preferably planar, strip-like, dimensionally stable sheath which reinforces and encloses said sealing sleeve radially on the outside, and further exhibits diameter-reducing clamping elements. Said clamping elements each comprise a clamping member and a clamping closure, the clamping elements interacting with guide elements integrally formed on the outer side of the sealing sleeve. Inwardly projecting supporting elements are provided on the inner side of the sleeve-ring casing parts. The sheath which reinforces and encloses the sealing sleeve radially on the outside comprises at least two ring-strip parts which engage one into the other with claw-like circumferential beads.

Inventor: FALLAHI AMIR
IPC: F21V7/09
Filed: 1993-12-07
Abstract: An apparatus includes a reflective surface (30) for high efficiency collection, transmission and emission of light. Light collected by ellipsoidal and hyperboloidal portions (32, 34) of the reflective surface (30), is directed into a light guide (28). Additionally, a paraboloidal portion may be added and used in combination with a lens element to distribute the light reflected by the reflective surface in a beam pattern. When used as an emitter lens profile is smaller than the overall diameter of the reflective surface. When used as a collector (20) the reflective surface (30) receives and concentrates light onto the end of a light pipe. <IMAGE>

Title: Method for digital data transmission
Inventor: HUBER JOHANNES PROF DR ING
IPC: H03K7/02
Filed: 1994-02-09
Abstract: A method for digital data transmission is indicated in which the symbols of a data stream to be transmitted and sequences of shaping bits are supplied to a pulse amplitude modulator in which the signal to be transmitted, during digital/analog conversion, undergoes signal shaping for signal values with an approximately Gaussian distribution. The shaped analog output signal of the pulse amplitude modulator is fed to a pre-emphasiser which counteracts the signal distortion due to the transmission path and whose output signal is transmitted via the connected transmission path. The transmitted signal is sampled at the end of the transmission path, is then further processed and fed to a discriminator. To achieve maximum signal shaping gain, the symbols of the data stream to be transmitted and the shaping bits are fed directly and separately from one another via different inputs to the pulse amplitude modulator without the intermediate connection of a scrambler.

Patent DE-4414298-A1 (DE)
Inventor: AHRENS HARALD DR
IPC: G11B31/00
Filed: 1994-04-23
Abstract: The invention relates to a method of transmitting digital information over a transmission channel such as a radio-broadcast channel.

Patent WO-8705660-A1 (WO)
Title: Actuating cylinder
Inventor: ENGFER ORTWIN
IPC: B60K28/16
Filed: 1987-02-26
Abstract: Actuating cylinder (2) which is a component of a system for limiting drive slippage and also serves to shut off a fuel feed system (28), which can be controlled by the drive slippage limiting system, and can for example be a diesel injection pump of a vehicle engine. The actuating cylinder (2) is provided with a pressurizable piston (9), a piston rod (10), two pressure springs (11, 12) incorporated in the pre-loaded state and between these an axially displaceable stop (13). The more strongly pre-loaded spring (12) presses the axially displaceable stop (13) against a stop (20) which is rigidly connected to the actuating cylinder (2). The less strongly pre-loaded pressure spring (11) presses against the axially displaceable stop (13) and presses against the piston (9). This pressure spring (11) is designed to be relatively stiff and during operation of the drive slippage limiting system is more or less strongly compressed by actuation of the piston (9). To achieve total switching off of the fuel feed system the piston (9) is actuated more strongly so that also the second strongly pre-loaded pressure spring (12), which is provided with a lower stiffness than the first pressure spring (11), is also compressed. The arrangement of the two pressure springs (11, 12) provides a fine adjustment of the drive slippage and simplifies the switching-off of the fuel feed system.
Patent WO-8906048-A1 (WO)
Inventor: RECZEK WERNER
IPC: H01L27/092
Filed: 1988-10-24
Abstract: En incorporant un transistor supplémentaire de déviation entre la sortie (OUT) et la tension d'alimentation (VDD) d'un circuit intégré, on réduit les risques d'un ''latch-up''. Lorsque surviennent à la sortie (OUT) des surtensions positives supérieures à la somme de la tension d'alimentation (VDD) et de la tension de passage du transistor de déviation, le transistor de déviation devient conducteur et établit une liaison de basse impédance entre la sortie (OUT) et la tension d'alimentation (VDD). Le transistor de déviation (BT) absorbe alors des porteurs supplémentaires de charge et augmente ainsi le courant nécessaire pour déclencher l'effet ''latch-up''. On peut incorporer un transistor supplémentaire de déviation dans des zones semiconductrices concaves qui reposent sur un potentiel fixe et dans des zones semiconductrices concaves équipées d'un potentiel variable.
