GUIDING DEVICE FOR A BALANCE COUNTER-WEIGHT
A METHOD OF MELT TRANSFERENCE FROM A BATH TO A RECIPIENT ABOVE THE BATH SURFACE AND AN APPARATUS FOR APPLYING THE METHOD
PROBEN-EINSPRITZVENTIL
Circuit arrangement to convert digital value into DC signal - has fixed and variable capacitors in AC bridge circuit with rectifiers and differential amplifier
Sheet feed mechanism multiposition suction cup - has cylinder end sealed by elastic moulding with adjusting screw
Two colour photocopying process - superimposes second image using opposite polarity on photosensitive layer in close contact with dielectric layer
PORTABLE AIR FILTER ASSEMBLY WITH PULSE JET SELF-CLEANING FILTERS
Motor vehicle alarm protection system - has triggering signal generator and delay store activated by second signal
Trailer for earthing overhead HV power line - has pivoted arm changing position of earthing rod without altering direction of axis
Di:phenyl-ether carboxylic acid derivs. prepn. - by oxidising methyl cpd. with di:chromate, used as plant protectant and polymer intermediates
Photoconductor with core of varying refractive index - keeps dispersion constant for all waves of wave composition for minimal propagation time dispersion
Measured value transfer between active converter and remote instrument - has sensor in transistor circuit with diode rectifier and two wire coupling with evaluator containing differential amplifier
triple-pass water boiler - has second pass divided into streams of different heat transfer to set mix temp.
Coating various surfaces, including plastics - by gluing polystyrene beads to them and compressing and smoothing with a heated plate under moderate pressure
Disc-shaped flying machine - has lift surfaces in form of powered radially pivoted annular segments with attitude control from stabilised cockpit
Travelling wave tube - using tungsten-copper vacuum sheath surrounding beryllium oxide bars holding delay line, and thus minimising thermal stresses
Multiple mixing chamber liq. gas burner - has inner tube with holes between two sections, inside perforated main tube
Seal for plate type valve - has elastic non-metallic layer between underside of seat and housing
