Title: Motor vehicle warning system for wrong way travel on slip road - has frequency generators inset in road surface transmitting to on-board logic
Inventor: ZINK UWE
IPC: G08G1/07
Filed: 1979-04-24
Abstract: A warning system for use on motor vehicles is activated when a driver attempts to join a motorway down an exit road. Two pulse generators are inset in the surface of the slip road at specific distances; one generates a 10 kHz signal and the other 5kHz. The generator signals are detected by an on-board sensor and are amplified before being separated by fitters. The two signals are fed to Schmitt triggers to produce a signal wave form. TTL distinguishers between the signals generate in both directions and activates an alarm for travel in the wrong direction. Inductive loops are triggered if the driver ignores the alarm and a camera records the vehicle.

Title: Excitation circuit for waveguide switches - has coils incorporated in anode-cathode circuits of thyristors, supplying pulses to gate of selected thyristor
Inventor: MAIER HUBERT ING GRAD
IPC: H01H47/32
Filed: 1979-06-01
Abstract: The energised waveguide switches operate in a selected position, and the circuit utilises as few components as possible, even it is extended for several waveguide switches. The switching function takes place when a pulse is supplied to a coil for the selected switch position. Each coil (1, 2) is incorporated in the anode-cathode circuit of a thyristor (3, 4). An ignition pulse is supplied to the gate of a thyristor, selected by a preselection switch (8), on actuation of a push-button (9). After the latter has been reset, a control pulse is applied to an electronic switch (12), interrupting the anode-cathode circuit of the thyristor and thus quenching the latter. Pref. the ignition pulse for the thyristor and the control pulse for the electronic switch are each generated by a differential component (10, 12).

Title: Work-roll changing wagon for rolling mills - where max. driving force for wagon is provided by hydraulic cylinders
IPC: B21B31/10
Filed: 1980-05-19
Abstract: The wagon can be driven in a direction parallel to the axes of the work rolls, and has clamps which grip the journals of two work-rolls so the latter can be drawn out of the mill. The wagon is driven along most of its allotted path by a motor. A high pulling force is required during the initial movement of the wagon when pulling the rolls out of the mill; and this initial movement is provided by a hydraulic cylinder instead of the motor. The pref. wagon has two hydraulic cylinders and a swivel claw which can be anchored in the floor of the rolling mill when the hydraulic cylinders are used to move the wagon. Used esp. on 4-high mills. The initial removal and the final insertion of the rolls require higher wagon driving forces than during the remainder of the travel of the wagon; these high forces are provided by hydraulic cylinders so the motor used to drive the wagon is not overloaded.

Title: Deposition welding on cylindrical bore of workpieces - using centrifugal force to hold filler powder in bore, and pyrometer for automatic process control
Inventor: SELNITSYN MIKAHIL GEORGIEVIC
IPC: B23K9/04
Filed: 1980-06-12
Abstract: A workpiece is clamped in the chuck of a driven headstock, which carries a ring receiving electric welding current from one pole of a power supply. The second pole of the power supply is connected to an electrode holder arm (I) which is mounted on a slide so the electrode can be moved towards or away from the bore of the workpiece, and its angle adjusted.

Title: FM system amplitude and/or phase error measurement - using frequency modulated and unmodulated test signal components
Inventor: EITZ GERHARD DIPL ING
IPC: G01R27/28
Filed: 1980-07-09
Abstract: A measurement signal contg. a frequency modulated and an unmodulated pulse is transferred and its received signal spectrum analysed and/or the received demodulated signal amplitude measured. A first section of the frequency modulated pulse envelope is chosen with a linearly increasing amplitude between initial (A1) and maximum (A2) values. A second section may additionally or alternatively be chosen with a linear decrease to a final value (A3). The sinusoidal carrier frequency vanes in a way similar to the envelope amplitude. The unmodulated signal (10) ramps at the same slope as the envelope between steps.
