PIRSCISSIONE CATALITICA FLUIDA.
AN INDEPENDENT THREAD HELICALLY COILED ON TO A STUD
MULTI-PACKAGING DEVICE
SUBSTITUIERTE INDOL-DERIVATE, IHRE HERSTELLUNG UND VERWENDUNG
IMIDAZOLCARBONSAEUREN UND DEREN DERIVATE
Traffic route noise screen wall elements - have sound absorbing filler in cassettes between concrete units, bars and panels
Torsional oscillation monitoring for turbo-set shafts - by filtering instantaneous generator power signal produced by Hall multiplier
Tear-open liq. pack or carton - has protruding strip of non-stretching material welded into transverse sealing seam
Ion emission microscope microanalyser with analysis site variation - using synchronisation of position and analysis to avoid cratering
Electroerosive metal machine system - uses stationary arc and forced transverse fluid flow between tool and work
Transfer mechanism for containers between chain conveyors - has transfer slide on guide track adjustable for height
Motor cyclist's kidney protection belt - with pockets and detachable storage bag with retaining strap
Trolley transportable in vehicle - has folding legs with additional upper rollers to run on vehicle load platform when folded
Phase controlled radiator group - has several radiators energised through Butler matrices, fixed value phase shifters and input circuits
Load lifting system against I:section girder - uses ropes reeved round pulleys in brackets on top flange
Shaping thermoplastic tube into smooth socket with collar - using equipment which provides a radial space during outwards expansion of the wall
Floating caisson for ship hull section - has flexible intermediate component between sidewall and base bearing against hull (NO 15.8.77)
Electrodynamic balance with pan suspended on oscillating string - has damping magnet in coil whose current is controlled by frequency pick=up
Protective coating for zinc - is obtd. by dipping into an oxygen-saturated calcium hydroxide soln.
Outlet pipe for liq. container, e.g. coffee machine - has vertical nozzle with variable height bottom rim and guide pin to prevent final drop from bursting
