Title: Antitheft marking for car - has licence details on security foil glued to insides of windows
Inventor: TEMPLIN WERNER
IPC: B60R13/10
Filed: 1978-09-23
Abstract: The security construction vehicle marking has a reflecting foil backing plate (10) provided with the character details. It is applied to the inside of the car windows using a clear adhesive. The backing plate is slotted and has the adhesive applied in selected strips. This ensures that any fraudulent removal damages the foil. The window mounting of the plate is easily viewed by the police. The attempt to remove the foil leads to residues on the windows which are rapidly spotted.

Title: Leak detection and water-cooled reactor - using electroacoustic transducer at circuit wall for early signalling of leak
Inventor: KITAHARA TANEMICHI
IPC: G21C17/00
Filed: 1978-11-09
Abstract: Leak in the cooling water of a nuclear reactor is detected by fitting an acousto-electric transducer at, on or near the wall of the cooling water circuit or a closely associated component. The acoustic vibrations generated by a leak are converted into electrical signals, signals of frequency 0.1-1 MHz being selected; an alarm is initiated to indicate the cooling water leak when the electric signals rise above a predetermined level determined by the background noise. More specifically, the acousto-electric transducer may be fitted to the pressure-retaining wall of the circuit, or to a wave-conducting element in the wall. A piezo-electric element may be used, more specifically a PZT element. A small leak can be detected before occurrence of radioactivity outside the cooling water circuit could be detected. Thus a high response sensitivity is achieved giving early detection.

Title: Efficiently vulcanising or curing cables - using tubular UHF gas and resistance heaters with intermediate lower energy tubes
Inventor: FOCHT HARRY
IPC: B29C48/00
Filed: 1978-11-25
Abstract: Rubber or polymer extrusions (and cable in particular) are vulcanised or crosslinked in equipment consisting of a tubular heating zone, filled with gas at atmospheric or higher pressure, and a cooling zone. The heating zone uses a combination of uhf and/or hot gas and/or resistance heating, with a number of successive uhf sections, and with intermediate separators and distance pieces of lower transmittivity for the uhf and/or gases. Rapid uniform vulcanisation/cure is obtd. because of high energy utilisation and hence short length.

Title: Coin face value determination in vending machine - is effected by detector system sensing weight and dimensions
Inventor: GOSDEN JULIAN KENNETH
IPC: G07D5/00
Filed: 1978-11-29
Abstract: The face value of coins in a coin operated machine is determined by a photo electric detector. The detector system differentiates between differen t dimensions and logic circuits sense compatibility of dimensions with the face value of the coin. Coins in automatic vending machines pass along a channel where photosensitive detectors sense different dimensions of each coin. Each detector has a light source comprising a light emitting diode. Detector outputs are passed into logic circuits comprising bistables with gated outputs which sense that dimensions are compatible with face value of coin. The detector system operates in conjunction with sensing of weight of coin.

Title: Locking cap for hexagonal bolt or nut - has flange screwing to support and collar deformable around bolt head to prevent rotation
Inventor: BOEER JOACHIM ING GRAD
IPC: F16B39/10
Filed: 1979-01-31
Abstract: The locking cap (1) consists of a plate with a circular hole pressed out of its centre to leave a circular shirt (4c) that encircles the hexagonal head (3) of the bolt (or nut) being locked.

Title: Catenary suspension for power cables - uses insulator chains on mast traverses with conductors held by connecting plates
Inventor: HERZIG KARLHEINZ DIPL ING
IPC: H02G7/20
Filed: 1979-02-10
Abstract: Stable location of overhead conductors is even when subject to strong wind pressure, is ensured by the catenary suspension on mast traverses using insulator chains. The insulators (2) at the suspension point of conductor bundle (5) are linked by metal sheet (3A) exhibiting a quadrangle shape. The sheet is of stainless steel while the sheets of other connecting points in the transmission line may have different configuration. The shape of the sheets connecting the insulators as well as the linkage spacing determine the angle of sway for a given wind load on the transmission line.

Title: Ellipse features of remote direction finder display - is computed by multiplying direction finder signals by phase shifted sense signal
Inventor: BAEUERLE HELMUT ING GRAD
IPC: G01S3/14
Filed: 1979-06-26
Abstract: In a Watson-Watt direction finder system, voltages proportional to the co-ordinates of the end points of the major and minor semi-axes of the DF ellipse are transmitted to operate a remote display. These voltages, UX1,UX2,UY1,UY2 are derived from the X and Y antenna signals, UX and UY, by multiplying them by in-phase and quadrature square waves, which are derived (5,4,6) from the sense antenna signal, UH. The phase of UH is varied by a voltage controlled phase shifter (3) to satisfy the condition UX1.UX2 + UY1.UY2 =US=O i.e. the phase changes until the control voltage US = 0. Multiplication operations are performed by 4-quadrant multipliers (1a,b,c,d,7,8) with low-pass filters (2a,b,c,d).

Title: Liquid sampler for wells and boreholes - with cylindrical shell lockable by top and bottom closure
Inventor: FITZNER KURT
IPC: G01N1/10
Filed: 1979-08-06
Abstract: A liquid sampler for use in wells and boreholes consists of a cylindrical open-ended shell which is lowered on a flexible element and can be closed on reaching the desired depth. A bottom closure is rigidly joined to the flexible element. The shell and the top closure can be moved relative to each other and to the flexible element. During the lowering operation the top closure and bottom closure are kept at a slight distance from the sealing faces of the shell to allow the liquid to enter the shell. This is a simple tool which causes no turbulence and takes samples exactly in accordance with the existing fluid layers.

Title: Loading platform with raise and lower switches - able to provide operating pulses only when safety switch is operated first
Inventor: PINGEL GEERT ING GRAD
IPC: B60P1/44
Filed: 1979-09-13
Abstract: The loading platform has a safety circuit containing a safety switch (9). Operating the safety switch twice in quick succession enables the 'raise' switch (10) or the 'lower' switch (11) depending on which is appropriate. The 'raise' or 'lower' switch can then be operated to raise or lower the platform. These two switches have no effect if operated without first operating the safety switch twice. The control circuitry for the platform drive returns to its initial state if a faulty operation is performed. The control circuitry contains relay contacts and hold devices (C1,C2) such as capacitors or timing relays.

Title: Exhaust gas driven turbocharger for IC engine - has motor operated exhaust gas by=pass valve with automatic controller
Inventor: WILL HANS DIETER ING GRAD
IPC: F02B37/18
Filed: 1980-02-12
Abstract: Control is effected by a motor (46)-operated valve (38) in a bypass pipe (37) connecting the exhaust manifold (16) to the silencer (26) and outlet. Diverting exhaust gas away from the turbine (20) reduces the amount of air delivered by the compressor (22) of the charger to the inlet manifold (12). The motor is controlled by an automatic regulator responsive to sensors, e.g. inlet manifold pressure (52) and temp. (54) and engine speed (56). The proposed control eliminates the need for altering ignition timing of the engine to suit changed conditions of oepration.
