FOELSOMHETSMAALEINSTRUMENT.
Heat collector panel for solar heater - has insulation layer of air between glass and semi absorbent layers
Decorative device using multiple reflections - has lamp bulbs and decorative devices supported by frame between conventional and semi reflective mirrors
Cellulose solution contg. acrylonitrile! polymer - di:methyl sulphoxide and formaldehyde, for spinning filaments and extruding films
Anchorage for vehicle tilting aerial - is insulated block with cavities for hinge pin and combined securing and connecting bolt
Crack detector for ceramic substrate - provides continuity measurement during application of torsional force from inflatable bladder between two arm members
Platform for transmitting transverse shock waves to ground - has anchored platform to which piston actuating mechanism is attached by deformable connections
Clamp for railway track signalling device - uses two clamp jaws to grip bottom flange of railway line to provide vibration resistant mounting
Conical wedge and sleeve anchorage for prestressing wire - uses two-part sleeve with stepped spiral ramp joint which offsets wedge slip by relative rotation of both parts
Slow speed thermo-mechanical motor - has thermal cylinder connected to double force crank drive and spring or weight to extract energy
Conveyor roller transport system - uses belt moving over rollers on fixed frame and on moving frame in steps synchronised to end stations
Angle setting appts. for vehicle headlights - adjusts according to load being carried by using dual piston and linkage mechanism
