Title: Travelling wave antenna with non dissipative termination - has waveguide with matched open end which reinforces main lobe
Inventor: WESTERMAN CHARLES WEBSTER
IPC: H01Q13/20
Filed: 1980-07-29
Abstract: An end-fire travelling wave antenna consists of a dielectric filled waveguide with non-resonant slots (23) cut across the wide side. A non-dissipative radiating termination is formed by continuing the waveguide a quarter wavelength beyond the last slot and leaving the end of the guide open. Three slots, longer than the antenna slots, are cut in this section to alter its impedance. This forms a quarter wave transformer to match the open end impedance to the antenna. Radiation from the open end adds in pahse and polarisation with the main antenna lobe. Measurement of an X-band antenna of this type showed a gain of 15.5dB compared with 15.2dB for the same antenna with a more expensive resistive termination.

Title: Insulating web made from insulating tape - wound into layers with joins overlapping and then cut to form flat mat
Inventor: HOYER PETER ING GRAD
IPC: B26D3/00
Filed: 1980-08-07
Abstract: The insulating web is made by winding an insulating tape in two layers around a former. An adhesive strip with adhesive on both sides is located between the layers across the two. The two layers are cut parallel to their long axis. After winding the first layer (5) of the insulating tape (6) an intermediate body (7,8) is placed on this layer. The second layer (11) is then wound and includes the intermediate body. The two layers are cut near the adhesive strip (10). The intermediate body is held to the periphery of the former (1) by a fixing device (9). The advantage lies in attaining by simple means distinct changes in the thickness of the insulation at the edges.

Title: Pilot monitoring circuit for transmission link - compares pilot level with reference and injects control information onto link
Inventor: REMME VOLKER JOACHIM
IPC: H04B3/10
Filed: 1980-08-27
Abstract: Pilot monitoring and adjustment circuitry is for telecommunications, or similar, transmission links. The pilot is compared with a reference level and can be used on each section of a multisection route to monitor for low or high gain and send an indicator signal to a main monitoring station to indicate a deviation from norm in a particular section. A pilot frequency, of typically 80.15MHz, is connected at the input/ output point of the circuit. It is filtered and received then input to the comparator for comparison with the reference level. The output of the comparator is connected through to a controlling logic circuit with outputs to an indicator display and to the modulator/transmitter connected back into the network. The output of the comparator to the delay network and to the power supply switch for the transmitter controls the duration and type of indicator signal transmitted back into the network to show the pilot state at the monitor circuit point.

Title: Arc welding set powered by asynchronous generator - has excitation capacitors shunted by primary winding of transformer which saturates when on no load
Inventor: CRACIUN MIRCEA DIPL ING
IPC: B23K9/10
Filed: 1980-10-16
Abstract: The application is to prime mover powered welding sets using an asynchronous generator with capacitor excitation. The proposed connection of the transformer is intended to assist in limiting the required size of the generator. The asynchronous generator (11), driven by an internal combustion engine (10), has excitation capacitors (19) connected in parallel across the terminals. The necessary reactors for compensation are formed by connecting the primary windings (12) of the welding transformer (13) in parallel with the capacitors. The transformer core is designed to saturate sharply at, or slightly above, the nominal generator no load voltage. The design and connection limits the no load voltage to a suitably low value, and at the same time ensures that, when on load, an adequate welding current is available. The welding transformer output is typically rectified (15).

Title: Wheel mounted transportable work bench - has supports which can be lowered or raised by system of levers operated by foot pedal
Inventor: DITTMER HEINZ-F
IPC: B25H1/04
Filed: 1980-10-23
Abstract: The transportable work bench has supports (3,4) on each corner. These supports are held in guide rails (7,8). A crank lever (9,10) has one end hinged to the upper end of each support while the other end is hinged on the trolley frame while the central hinge is connected by a linkage (11,12) to a double lever (13) in the frame centre. The double lever pivots on its centre point (15) and is operated by a pedal (14) so that when the pedal is depressed, the linkage pushes the knee lever straight, thus forcing the supports down till the support ends (16) are on the ground. This ensures that the bench does not roll away while in use.

Title: Digital display of lift caused by eccentric shaft - uses linear and sine-cosine potentiometers without transmission gears
Inventor: SIEMANN HANS-ULRICH
IPC: B21B38/10
Filed: 1980-11-26
Abstract: A circuit for provision of a digital indication of the displacement resulting from the rotation of an eccentric shaft enables a mechanical gear transmission for sinusoidal conversion and esp. displacement sensors to be dispensed with. A linear and a sine/cosine potentiometer are connected to the eccentric shaft so as to be equally displaceable on either side of a null position over a defined shaft rotation range. They produce a positive voltage in one part of their angular range and a negative voltage in another. A logic circuit converts the linear potentiometer positive and negative voltages into equal sinusoidal magnitudes which are fed directly or via an inversion, depending on their sign, to a digital display.

Patent DE-3114371-A1 (DE)
Inventor: THOMAS ALFRED
IPC: B29C48/475
Filed: 1981-04-09
Abstract: In the production of a tubular extruded section of thermoplastic material, the actual length of an extruded section at the end of the extrusion operation may be smaller or greater than the length of the extruded section which passed through the discharge orifice of the extrusion head during extrusion. If the wall thickness of the extruded section is varied during extrusion in accordance with a given program, inaccuracies in regard to distribution of the wall thickness over the length of the extruded section can be reduced by detecting the length of the extruded section which passes through the discharge orifice, and controlling the means for producing the programmed variation in wall thickness, in dependence on that discharge length. The same effect can be achieved by controlling the means for producing the programmed variation in wall thickness, in dependence on discharge speed and time. A higher degree of accuracy can be achieved by measuring the discharge length or discharge speed on the one hand and on the other hand the respective associated effective length of the extruded section, or the speed of movement of the free end of the extruded section, comparing those two detected values, and producing corrective variations in wall thickness in dependence on the result of the comparison operation.

Patent DE-3134049-A1 (DE)
Title: Magnet control with external actuators
Inventor: WEH HERBERT PROF DR ING
IPC: B61B13/08
Filed: 1981-08-28
Abstract: As a result of displacing the control element out of the magnet, advantages are obtained with respect to the response speed with simultaneous reduction of the power of actuator and battery. Even using a mechanical power reduction has in this respect a favourable effect on the design. It is expected that the time constant of the winding of the control motors will be more than one factor (10) smaller than in the controlled magnets. The necessary voltage overshoots can be drastically reduced in this way. In this way, it is possible to considerably reduce the reaction time of the controlled magnets. The energy consumption for supporting technology and control technology can be further reduced in comparison with previous solutions. The development of higher response speeds of the magnet system is promoted by virtue of the fact that the supporting and control magnets can be designed to have a greatly reduced weight. The weights of the vehicles can be reduced and the energy consumption for propulsion can be lowered. Since the masses of the permanent magnets are also reduced and the manufacturing costs are limited, a favourable influence on the price of the vehicles can be expected. For the design of the track, the use of magnets with increased response speed means it becomes possible to realise greater track tolerances.
