PROCESS FOR FILLING A BAG INSIDE A TANK WITH A BEVERAGE CONTAINING CARBONIC ACID,PARTICULARLY BEER
VERFORMBARE WAERMEDAEMMBAHN
Bubble-free (tubular) silica glass prodn. - e.g. for lamps, by heating waste silica powder to convert it to cristobalite
Magnetic float level indicator for liq. - uses magnet on float to maintain alignment with ferromagnetic balls in cage around container wall
Antiskid control for train wheels - has three threshold levels for optimum braking and traction
EDM correction system for curved contours - uses vector monitoring for trailing electrode wire to maintain straight cut
Summing and subtracting planetary gear train - has two sets of epicyclic gears with three input shafts
Auxiliary box for use in workshop - has stalk attached to base to allow swivelling on trolley stand
Plastics moulded driving mirror - has internal ribs to reinforce snap fastening edges
Track laying vehicle with hydrostatic actuation - has integrating drive with clutches for coupling to planetary gear drive
Random pattern dyeing process - uses irregular blanks scattered over fabric before dyestuff application
Accumulator plate packaging machine - has cam-operated reciprocating pincers and hot welding mechanism (CS 31.5.78)
Tone control circuit for higher frequencies - has negative feedback AF amplifier with two resistive voltage dividers and capacitor connected to give positive feedback
Paper mfg. compsn. based on carbohydrate and gelatinous compsn. - giving resistance to tearing, breaking and wetting and avoiding pollution and deforestation
Flame cutter for cutting intersecting pipe inter-penetration curves - is held on parallelogram scissor linkage driven by guide cam
Interlocking wall building blocks - have lengthways grooves engaged by base panel rib or narrow strips between rows
Seating unit with metal frame - having slots to locate edges of panels and holes for arm rest fastening
LF output amplifier stage - has operational amplifier with transistor output coupled to inputs to drive woofer in acoustic system
Control for piezoelectric crystal grinder - uses filter circuit to generate signal representing natural frequency of crystal
