Title: Vehicle detection to prevent travel in wrong direction - using sensors inset into exit slip-road surface to activate display if vehicle passes in wrong direction
Inventor: FRENTRUP ADOLF
IPC: G08G1/02
Filed: 1978-12-09
Abstract: A detector and coupled display is used to avoid the possibility that road vehicles travel in the wrong direction on motorway exit slip rodas. Normally, exits from a motorway are made over a slip road that eventually forms a two way section that also has an entry slip road. Two pairs of rollers set across the exit slip road are set in motion ny the passage of a vehicle. If a vehicle attempts to enter incorrectly the rollers direction is reversed. This is detected by electronic circuitry and a display is actuated to warn the driver. An alternate system uses contact plates instead of rollers. A further version uses optical detectors or radar to detect a vehicle travelling in the wrong direction.
Patent DE-2904973-A1 (DE)
Title: Machine tool with overhung beam - has hydraulically loaded tie rod to exert counterbalancing moment

Patent DE-2914133-A1 (DE)
Title: Tapping point on optical data link - passes intense light transversely through light guide and demodulating resultant output
Inventor: POPP WOLFGANG DR ING
IPC: G02F1/35
Filed: 1979-04-07
Abstract: At the intermediate receiving station or tapping point a high intensity light beam, of frequency different to that of the transmission frequency, is propagated transversely across the light guide. The intensity is such that at the crossing point the optical fibres operate on their non-linear characteristic such that the beam emerging from the fibres is a mutual modulation of the two frequencies. This beam is then demodulated to leave, as output at the intermediate station, a light signal having the same frequency as the main transmission. The proposed method eliminates the need to make very accurate welds between two fibre guides or to convert from optical to electrical signals and back again to each intermediate station. It also gives light amplification of the extracted signal.

Title: Workpiece coating plant with interconnecting conveyor - has pneumatically or electromagnetically operated end stops for grouping workpieces prior to coating
Filed: 1979-05-18
Abstract: The coating plant with several machines has end stops (12, 13) that move into the path of the workpieces (2) as they enter the coating machine (6). The end stops may be moved pneumatically or electromagnetically. A sensor (15) detects the passing of the rear edge of the last workpiece and produces a pulse that initiates the movement of the end stops. The end stops group the workpieces together and, therefore, eliminate any wandering caused by the different speeds of the workpiece conveyors(s). Multiple layer laminates can therefore, be fabricated with precise alignment and consequently less waste.
