Title: Battery powered grazing land fence - has threshold circuit which connects battery to fence only when its voltage is sufficient
Inventor: HEIMROTH HERBERT
IPC: H05C1/04
Filed: 1977-05-28
Abstract: The fence has a supply battery, an h.v. pulse generator between the battery and the fence, and a battery testing circuit in parallel with the battery. The circuit has a display device and a switch for its connection to the battery. The battery testing circuit has a threshold circuit (T1, ZD1) to whose input, when the switch (S1) is closed, a voltage proportional to the battery voltage is applied. A relay (K1) is connected to its output. When the relay is not energised, its contact (1) is connected to one display element (LED2), and when it is energised, the contact (1) is connected to a second display element (LED1). The display element connected to the contact when the switch is closed, is connected to at least a part of the battery voltage. The threshold circuit threshold is such, that when the switch is closed, the relay is energised only when the battery voltage is sufficient to ensure the fence correct operation.

Title: Passive electron=optical indicator cell - has nematic liq. crystal in helix structure with two plates carrying control electrodes
Inventor: VIENNET RENE
IPC: G02F1/1335
Filed: 1977-08-12
Abstract: Between the two plates of the electrooptical indicator cell is contained the fluid crystal and behind and in front of the plates there are two polarisers. Molecules of two colours are admixed with the fluid crystal (3) to determine the colour of the indicator background. One of the polarisers (7) may be selective and the other (8) neutral, so that the indication coloured with one colour appears on a background coloured with another colour. The selective polariser may be positioned in front of the cell, while the neutral polariser is behind it. Both polarisers may be selective and have the same property, so that the indication and the background have the same colour, but different shades.

Title: Rotating field magnetic precipitator - has magnetic field permeated working medium fitted inside magnetic rotary field generated by three=phase windings
Inventor: SCHUSTER KARL
IPC: B03C1/10
Filed: 1977-08-26
Abstract: The precipitator serves for removing magnetisable particles of sizes less than one millimicron from gaseous or fluid media. The installation consists of column (2) forming a rotary field generator. The column is built-up from a cylindrical bundle of sheets (3) with central opening (4). On the inner surface of the bundle there is a number of grooves (5) with inserted three-phase windings (6). The opening (4) is fitted with a tube (8) of non-magnetic material. The space surrounded by the windings represents a magnetic working space. When AC-current is fed into the windings (6) a rotary field is produced in the space (9) rotating around the axis (10) with an angular speed of omega. Gaseous - or fluid media containing magnetic admixtures are introduced into the working space (9) producing configurations of particles which rotate within the magnetic field around their centre of gravity. During the rotation the configurations shed their minute size particles.

Title: Hose internal coating machine - fills hose with liq. coating material before pulling between squeezing rollers to regulate coating thickness
Inventor: SCHULTE KLAUS DR
IPC: B05D7/22
Filed: 1978-01-11
Abstract: The process internally coats endless hoses made of plastics sheet or impermeable textile material. The hose (41) is pulled off a braked roll and filled with a quantity of coating material in liquid form, and it is then pulled between a pair of squeezing rollers (31, 32). It can then be coiled up again, and before passing through the squeezing rollers it can be run in a zig-zag pattern, filled with coating material, round a series of guide rollers (24, 26, 28). Alternatively it can be passed round the guide rollers before filling, and punctured to allow topping up with coating material. External coating can also be applied, either before or after the internal coating.

Title: Pressure pipe esp. primary coolant duct with peripheral weld - has internal ring covering weld to limit aperture if weld ruptures
Inventor: MICHEL EBERHARD ING GRAD
IPC: F16L13/02
Filed: 1978-08-07
Abstract: A pressure pipeline has a weld between adjacent sections. Inside the pipe a ring covers the region of the weld seam. More specifically, the ring is attached to the internal lining of the pipe or duct. The ring may be composed of a number of parts connected together. Used esp. for prim. coolant ducts in a nuclear power plant, where the fracture of a peripheral weld may be regarded as the max. credible accident. The ring stops the two parts of the pipe from sepg. if a crack should arise in thise region; in this way, only a comparatively small leak results. Access from the outside for inspection purposes is still possible.

Title: Sweep signal generator with control Voltage device - corrects nonlinearity of capacitance diodes by pre-distortion of control signal
Inventor: SUESSMUTH WILHELM DIPL ING
IPC: H03B23/00
Filed: 1978-08-16
Abstract: The control voltage generator delivers a linearly rising and/or falling control voltage. A VCO is controlled by at least one capacitance diode, with non-linearity of its voltage-frequency characteristic corrected by a compensation circuit. An equaliser with a multiplication circuit is inserted before the capacitance diode in the signal path of the still linear control voltage. The multiplication circuit voltage-time characteristic is such, that starting from the zero value of the linear in time control voltage a predistorted control voltage is produced by squaring and used for control of the capacitance diodes.
