DISPLAY DISTORTION CORRECTOR FOR ELECTRON BEAM DEVICE
FISHING LAMP USED ON SHIP
PATIENT MOVING DEVICE
Controller for electric heating system - uses thermal inertia of walls to smooth heat fluctuations and measures wall temp. to initiate extra heating when wall temp. falls
3-Pyridyl-4-hydroxy-thiazolidine-2-thione derivs. - useful as anthelmintic agents, esp. against nematodes
Elbowed coaxial plug for HF line - has walls of shell bent over to cover connection with insulation between shell and pin
Rotary fermenting vessel producing fuel gas from manure etc. - fed direct from stables without pre:pulping
Regulation mechanism for constant or variable light sources - uses photocell, and potentiometer adjusted RC oscillator and frequency divider to prevent hunting effects
Vertical deflection frame sweep circuit - has reverse counter filled with successive binary words which triggers each sweep at end of count down to zero from each number
Economic driving of motor vehicle - using engine revolution counter and lamps for indicating fuel consumption and excessive acceleration conditions
Linear actuator assembled by metal deformation - has cylinder made from drawn tube with shoulders retaining sealing and bearing rings and separate base
Hanger for wall covering - has spiked timbers framing wall with covering panel pressed into place
Insulating panel for partition walls - has cork core covered on each side with glass fibre with resin coating
