PROFILE D'ETANCHEITE POUR OBTURATEUR D'OUVERTURES, NOTAMMENT DES CAISSES DE VEHICULES AUTOMOBILES
Plant to mfr. compost by fermenting organic waste - uses modular parallelepiped, fermenting vessels served by common mobile discharge conveyor
Heat exchanger prodn. esp. radiators - involves soldering metal parts using flux contg. rosin
Aircraft-towed tubular advertising object - is aerodynamically inflated by air flow from front opening to smaller-area outlet at rear (BR 20.4.81)
Multi-piece extrusion screw with self-tightening segment couplings - for assembly of selective replacement of complex screw profiles
Vibration reducer for vehicle engine - detects engine movement to control fuel injection to compensate ignition point changes
Bidirectional T=connector for optical fibres - has two couplers allowing each transmitting-receiving station to be interconnected on common optical bus
Continuous sheet metal strip cutter - has winding drum feeding cutters passing to separating rolls with sheet tensioner(SE 20.7.81)
Electric circuitry overheating detection system - uses burner, connected to hydrogen source and photomultiplier to sense gases given off prior to ignition
Amplifier for emissions generated by geometrical shapes - comprises printed circuit array of circles with exteriorly contiguous spirals mounted on insulating board
Radar demodulation circuit eliminating secondary lobes - has FETs for earthing multiplier when receiving zero signal to reduce noise
Central heating and air conditioning - combines external insulating with air circulating system, heat exchanger and underfloor heating
Video image superimposition system - permits alignment and shifting of images to be positioned over raster scanned base images
Distress signalling device using inflatable balloon - uses compressed gas to release balloon valve from inflation block and is packed to be worn on belt
