KATALYSIERTE POLYISOCYANATUEBERZUGSMASSEN UND VERFAHREN ZU IHRER HERSTELLUNG
Non-drip stopper for honey dispenser - has cutting edge round bottom of shaped stopper preventing excessive build=up
Tilter for rolled metal bars - esp. for edge tilting billets prior to a diamond-rolling pass
Speed and distance measuring device - has accelerometer acting in direction of movement and in opposite direction
Copy grinding machine for wooden workpieces - drives model and workpiece in sync. manner so that oscillation of machines is controlled
Hydraulic pump and motor acting on differential pressure - have single rotor working as motor and pump on opposite sides
Embankment construction resistant to erosion and earth pressure - has layers of vegetation and earth fill incorporated in open structure
Spun conical centrifuge drum - has ring groove with back tapered upper surface and enlarged wall thickness
Range finder using HF and LF signals - has transceiver unit at first point and reflection unit at second point
Communications system with channel sharing - allows one channel to be shared between several subscribers by employing digital techniques
Coupling system for concrete piles - uses clamping pins drivable into coupling holes in connecting parts
Piston and cylinder for high speed press - has axially adjustable support sleeve which can be locked in cylinder and operated by external actuator
Telephone speech transmission system - uses carbon granule microphone to transmit signals over telephone line for amplification at receiving end
Winding machine for insulating tape - wraps around toroidal component using endless conveyor belt periodically reversing direction
Miniature wound spring motor - has bending momentum of coiled spring transmitted to power driven shaft
Opto-electronic sensing system - has MIS capacitor with buried layer for each sensor, and also for read=out register
Plant furrow closing plough - has lead cable guide with limit switch rail to control selector valve for double acting hydraulic cylinder which adjusts position
Shaft end of central heating circulator - is hexagonal to allow barring tool to rotate shaft without exerting bending moment on it
Printing plate prodn. method - uses carbon fabric and mesh to produce raster of squared nature with close etch control
Rolling mill train, esp. for rolling profiles in metal strip - where one pair of rolls is fitted on each side of the roll stands
