REMOVING HARDENED ORGANIC MATERIALS DURING FABRICATION OF INTEGRATED CIRCUITS
Coating copper and aluminium e.g. wire with plastics - after removing hydrogen by tempering in vacuo or in hydrogen-free atmos.
Two-door motor vehicle with antitheft protection - has activating coded signal transmitter, with lockable passenger door and driver's door lock responsive to transmitter
Hollow concrete ceiling lost formwork slab - has T=shaped ribs filling recesses in open sided hollow units
Carousel type punch machine - has revolving table with vertically moving members controlled by overhead circular sloping face
Electrochemical erosion esp. of titanium workpiece - flooded with liquid electrolyte uses subsidiary circuit to reduce unwanted erosion
Digital regenerator for alternate mark inversion coded signals - uses discriminators and D=flip=flop(s) with verification of output signals
Video amplifier overvoltage protection circuit - has reverse-biased diode connected between amplifier output and collector bias terminal
Two-speed gearbox for electric drill - uses friction clutch with slip torque matched to selected gear ratio
Straight through furnace esp. for bricks and ceramic prods. - has two parallel tunnels with gas flow generally opposite to product flow
Vending machine with coin evaluator and automatic dispenser - has goods-release control sliding and pivoting allowing easy access for maintenance
