STABILISERINGSBANDASJE FOR KNELEDD.
Forming capacitance in integrated circuit - utilising two level metallisation with dielectric between the levels
Polymerising ethylene with ziegler catalyst - contg. at least two different halide(s)
HV automatic extinction circuit breaker - uses auxiliary contacts and mechanical linkage ensuring correct operating sequence
Anchor for cable in concrete - has perforated plate sandwiched between sealing cap and steel support plate
Side tipping installation for beet carrying vehicles - has tipping platforms on both sides of tipping bunker floor of which is constructed as band conveyor
Writing implement fitting onto finger - comprises finger stall which supports pencil or pen or is incorporated into body of brush
Moist heat treatment for concrete products - in tunnel kiln with preheating, humid heating, isothermal holding and cooling zones
Band saw sharpening, hardening and setting process - uses cold forging to raise edges of tooth and machine which automatically deposits tungsten carbide on tooth tips
