Title: Heat engine for utilising environmental heat
IPC: F02C3/32
Filed: 1985-06-19
Abstract: The invention relates to a heat engine for utilising environmental heat of uniform temperature in internal equilibrium, such as, for example, heat of normal air or water. The heat engine is in particular suitable for major stationary installations such as, for example, for driving electric generators in power stations. In order to be able at all to utilise heat of uniform temperature, that is to say without presence of a natural heat gradient relative to a heat reservoir located outside the heat engine, the heat engine is designed according to the invention with a two-part gas circulation. In this case, the working medium of one part circulation is compressed via a two-stage compressor with intercooling and fed to a two-component nozzle, while the other part of the working medium (cold and uncompressed) is drawn directly into the two-component nozzle after preceding heat absorption from the surroundings and from the waste heat generated in the intercooling. The mixed product obtained in this way in the two-component nozzle from the two working medium components from both part circulations under the new pressure (the mixed pressure) and at the new temperature (the mixing temperature) is eventually fed to an expansion machine (gas turbine), expanded and, after cooling, returned again to the surroundings (with open operating procedure) or to the heat exchanger (with closed operating procedure) for renewed heat absorption. Since the working gas beforehand in ... Original abstract incomplete.

Title: Device for securing motor vehicles against theft and for relocating stolen motor vehicles
Inventor: SKALIKS GUNTRAM
IPC: B60R25/33
Filed: 1985-07-10
Abstract: The device for securing motor vehicles (1) against theft and for relocating stolen motor vehicles (1) has a plurality of triggering contacts (2 to 5) which are arranged at weak points, such as break-in points (door, boot lid, bonnet) and towing points of the motor vehicle (1), and interact with a pulse generator (6) in the motor vehicle (1), and has a transmitter (7) which is invisibly arranged in the motor vehicle (1), preferably has its own power supply and emits a signal with messages to a receiver of a receiver network which is connected to police stations. The device according to the invention will not deter a determined thief directly, but will allow him to proceed undisturbed at first, attaching him unawares to an invisible "long leash", by means of which it is possible to locate and track the vehicle in question and to find the vehicle and possibly the thief. <IMAGE>
Patent DE-3530395-A1 (DE)
Title: Oscillation damper for vehicles
Inventor: GRUNDEI MANFRED ING GRAD
IPC: F16F9/348
Filed: 1985-08-24
Abstract: The present invention provides a damping valve for an oscillation damper, in particular a piston valve assigned to the damping of the extension movement, and does this by virtue of the fact that the cross-section of the continuously open passage between the working spaces, which passage is formed by the damping valve, is constructed to be adjustable. A changing cross-section of the continuously open passage by means of a simple, operationally reliable and easily adjustable construction is achieved by virtue of the fact that the cross-section of passage formed by an inner wall of a projection of a spring-loaded valve plate and by a component fixed to the piston rod is formed by an adjustable body which can be adjusted in the axial direction of the piston rod and interacts with the projection of the valve plate.

Title: Demodulation method for binary frequency-modulated signals
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04L27/156
Filed: 1985-10-09
Abstract: The invention relates to a simple method for demodulating an FSK signal, only minor signal distortion occurring. In this method, counting values (Z) are initially formed which correspond to the lengths of half-cycles of the FSK signal. The counting values (Z) are converted into signal bytes which are used to form an output signal (ED). The counting values (Z) are converted into signal bytes by evaluating the counting values (Z) in terms of them exceeding or falling below threshold values for allocation to an assigned frequency (f1, f2), and by establishing the exact changeover time (x) when counting values (Z) occur in an alternating range (WB), i.e. between the threshold values. <IMAGE>

Title: Process for the preparation of olefins
Inventor: ZIMMERMANN HEINZ DR
IPC: C10G69/06
Filed: 1986-05-16
Abstract: A process for the preparation of olefins from a hydrocarbon feedstock stream boiling below 200 DEG C is described. In order to utilise the lower carbonisation tendency of gas cracking and the higher propylene content of the products, it is proposed that the feedstock stream is reacted catalytically to give liquid gas and the liquid gas is cracked to give olefins. The process can be used in particular for the production of propylene and ethylene from naphtha.

Title: Method and device for producing a profile image representation of the surface of a workpiece
Inventor: WEINGARTNER ALBIN DIPL ING
IPC: G01B11/24
Filed: 1987-02-05
Abstract: With the aid of the triangulation method which is known per se and can be used for distance measurement, a profile image representation of a surface of a workpiece is acquired. A laser light source (3) transmits a light beam to the surface of the workpiece via a condenser (4) and a periodically pivoted deflection mirror (5). By pivoting the mirror, the surface of the workpiece is scanned along a scanning line. The light beam which is reflected from the surface of the workpiece is deflected by the deflection mirror via a lens (7) to a two-dimensional position-sensitive photodiode (8). The output signal of the photodiode represents the fluctuations in height, that is to say the profile section of the surface of the workpiece, as a different signal. If the workpiece (1) is moved in relation to the scanning arrangement, a perspective view of the surface of the workpiece can be obtained on a display device by means of representations of the profile section illustrated at discrete intervals. <IMAGE>

IPC: F15B15/08
Filed: 1987-02-20
Abstract: A rotating drive mechanism for swinging doors, especially on vehicles, with a helical transmission consisting of a stator that is rigidly connected to the housing of the rotating drive mechanism, a rotor that can rotate but cannot move axially and that is rigidly connected to the driveshaft, a coupling component that moves axially to rotate the rotor in relation to the stator, and a pneumatic or hydraulic drive cylinder with a piston rod that is connected to the coupling component. The drive cylinder is an annular cylinder that has an outer and an inner jacket as well as an annular piston between the inner and the outer jacket. The coupling component is a nut that extends into the inner cylinder jacket and surrounds a rotor in the form of a threaded spindle. The rotor extends coaxially through the inside of the inner jacket and is, where it emerges from the housing, in one piece with the stub of the takeoff shaft. The coupling component is non-rotationally connected to an axial positioning mechanism that has rollers that travel in a positioning slot in the stator.
