Title: Fibre gyroscope
Inventor: AUST HEINRICH DIPL ING
IPC: G01C19/72
Filed: 1987-12-12
Abstract: A fibre gyroscope is proposed, having a light source, e.g. laser or superluminescent diode (2), in which the light beams circulating in opposite directions in a sensor coil (5) are phase-modulated by means of an optical phase modulator (6). An electrical useful signal is obtained from the superposed light beams by means of a detector (1) and from this a rate-of-rotation signal is obtained by phase-sensitive rectification (in 8). By means of a detector (1), a stabilisation signal depending on the power of the light source (2) is obtained for the purpose of stabilising the power of the light source (2). For obtaining the useful signal and the stabilisation signal, only one detector (1) is provided, downstream of which a filter (9) is connected for separating the useful signal and the stabilisation signal. <IMAGE>

Title: Fog machine and process for generating fog
Inventor: VOEGELI WERNER
IPC: A63J5/02
Filed: 1988-01-15
Abstract: In discotheques, fog machines are used which evaporate a fluid, e.g. propylene glycol, characterised by a certain fog dissipation time. There is a defined amount of various fluids of which each has a different fog dissipation time. In order to be able to generate fogs of different dissipation times with a single machine, either various fluids are mixed and the fluid is evaporated or a fluid from one or more tanks filled with different fluids is fed to an evaporator of a fog machine.

Title: Process for producing plastic bottles and an extrusion blow-moulding machine for carrying out the process
Inventor: EFFENBERGER ALFRED DIPL ING
IPC: B29C48/92
Filed: 1988-06-06
Abstract: In the production of plastic bottles with, for example, a flat-rectangular cross-section, to be able both to work in an energy-saving manner and to make do with a blow-moulding machine which can be constructed in a simple design, the blowing station of the usual construction is preceded by a preblowing station, in which there is blown a preform which has a rotationally symmetrical shape and constant wall thickness and is subsequently brought into the blowing station and converted there into the final bottle shape by blowing. These two operations are coordinated in time with each other in such a way that, immediately after it has achieved adequate stability, the preform can be received by the finishing blow mould and can be further processed. The timed coordination can be controlled according to requirements by temporarily stopping the extruder.

Title: Method and device for treating liquids and/or gases by means of UV light sources
Inventor: WEDEKAMP HORST
IPC: A61L2/10
Filed: 1988-11-04
Abstract: In the treatment of liquids and/or gases, in particular in the case of sterilisation by means of UV light sources, exclusive use is made of UV light sources which have the same active spectral lines. It is thus possible for the medium concerned to be exposed only to a single wavelength. In order to permit more effective treatment of liquids and/or gases, use is made inside a single common device of a plurality of mutually differing UV light sources which respectively have different spectral lines. By simultaneously switching on the different UV light sources, turning them on in a combined fashion or respectively turning them on separately, it is thus possible to treat the medium with different spectral lines in appropriate combinations.

Title: Brake and steering brake system for utility vehicles, in particular for agricultural tractors with trailer operation
Inventor: JORDAN BERNHARD
IPC: B62D1/18
Filed: 1988-12-22
Abstract: Brake and steering brake systems in which the force exerted on the brake pedals is directed via mechanical linkages to the service brakes of the wheels of the vehicle require increased expenditure for uniform braking effects to be achieved at both sides of the vehicle. The cause of this is a pressure sensor which is required to actuate a trailer brake valve as a function of the pedal force at the brake pedals and is installed in one of the linkages. In order to achieve identical braking effects on both sides of the vehicle, the axle (3) on which the brake pedals (1, 2) are mounted is movably guided at least approximately in the longitudinal direction of the vehicle, and the pressure sensor (12) can be actuated, as a function of the movement of the axle (3) brought about by an actuation of the brake, with the effect of increasing pressure. This arrangement of the pressure sensor permits the trailer brake valve to be actuated both during normal braking operation and also during any steering braking operations. <IMAGE>

Title: Insert for clamping thin-walled hollow profiles, especially for internal pressure tests
Inventor: RUPP ANDREAS DIPL ING
IPC: G01N3/12
Filed: 1989-02-17
Abstract: By means of the invention, an insert is provided for the clamping of thin-walled hollow profiles, which comprises a supporting part whose external cross-section is complementary to the internal cross-section of the hollow profile. The rigid supporting part is divided into a plurality of supporting wedge parts and is supplemented by means of an elastomeric supporting part onto which is mounted, preferably, a hose which can accept a flow medium for internal pressure tests.

Title: Transition termination for medium-voltage cables
Inventor: OSTERWOHLDT KARL HEINZ
IPC: H02G15/06
Filed: 1989-04-04
Abstract: Paper-insulated three-conductor cables are closed off in the case of medium voltages in such a way that the individual cores are spread out within an attached termination housing. The cores are led out from the housing with insulators. Terminations of this kind are now to be regarded as special end devices of paper-insulated cables and have been developed for connection to air-insulated switchgear. For compact switchgear which has been reduced in size, paper-insulated cores are, however, not suitable because of their low degree of flexibility. The invention proposes a transition termination for a paper-insulated three-conductor cable 4 for connection to a switching installation 17, wherein a connection with plastic-insulated leads 8 is produced within the termination housing 1 for the paper-insulated three-conductor cable 4. A transition termination of this kind can, in particular, be used in the case of compact SF6 switching installations. <IMAGE>
Patent DE-3913975-A1 (DE)
Inventor: KERNER HORST
IPC: G01R19/25
Filed: 1989-04-27
Abstract: The invention relates to a method and an arrangement for data acquisition and compression for off-normal recording in monitoring systems, in which the off-normal signals are sampled as analogue electrical variables, digitised and evaluated. To achieve optimum data compression without restricting the possibilities for reconstruction, the sampling frequency used for digitisation is made dependent on the gradient of the variation of the analogue electrical variable. The invention can be used mainly in determining off-normal values in power supply or transmission systems. <IMAGE>
