Process for producing a rough electrically insulating foil of polypropylene.
AQUEOUS DISPERSIONS OF RESINS THAT ARE SUITABLE AS COATING MATERIALS OR VARNISH BINDERS
IMPROVEMENTS IN OR RELATING TO HYDRAULIC ACTUATOR CONTROLS
Blood pressure measuring appts. - uses ultrasonic waves with volume variation of injected gas bubbles indicated from size of reflected waves
Buffer store in moving length of material - maintains folded amount by varying measured feed speeds, resets control by interposed detector
Filter bag for industrial vacuum cleaners - has filter mat set in cut-out for easy mechanical mass production
IC engine exhaust afterburner with separate ignition - has gas inlet in large flat baffle in combustion chamber, facing flow-reversing wall
Domestic hot water plant - has additional external heat exchanger with switch-over valve
Half tone tactile pictures - have deep etched metal master with rubber moulded prints suitable for feeling by blind people
Safety system for prim. circuit esp. of boiling water reactor - has ultrasonic detector head mounted externally on pressure vessel
Unloader device for removing stacked goods from pallet - has sensors on lift support monitoring pallet transfers and reducing time between pallet changes
Protection circuit for rotor winding of AC slip-ring motor - has disconnection gap created by over-current release triggered by transformer
Low consumption motor - uses two independent motors with one battery driven so as to provide current supply for second
Roof suspension bracket for cable pipes - has open base for top bolt access and contoured sides with overlap base plus bolt fixing
