Title: Push button operated on-off water valve - has permanent magnet to lift piston off pilot hole in membrane
Inventor: EGOROFF DIMITRI
IPC: F16K31/08
Filed: 1974-09-18
Abstract: A push button operated shut off valve on a water supply point has a permanent magnet (19) located inside the manually operated push button (14). The magnet acts on a valve piston (22) such that an attached pilot plug (21) lifts off the centre hole in the valve membrane (20). This causes a pressure drop in the valve chamber (18) since the water can escape through the outlet pipe (16). The membrane is now able to deflect away from the outlet pipe so that water from the inlet (13) can directly flow to the outlet (16). The first push on button (14) locks it in the valve open position, a second push returns the button so that the valve is shut again.

Title: Matted fibre web cutting device - cutting accurate lengths by controlling web feed directly by lengths of moving web using contact rollers
Inventor: FRITZ JOSEF
IPC: B26D5/40
Filed: 1974-09-25
Abstract: The parent patent describes resin impregnated matted fibre web cutting device including a web roll support and a web feeding rollers, >=1 of which is associated with a winding roller for the protective layer of the web. Web is slit by a stationary knife and stopped wen a required length of web has been fed by the rollers. Rollers are driven under the control of a web length measuring device. Following stopping the web a transverse cutter severs the slit portion of web into a sheet. In this addn. the length measuring device is driven by derivation of the control signal directly from the moving web (e.g., through the intermediary of a measuring wheel). Slip between the web and feed rollers leading to faulty length cutting is prevented.

Title: Air flow rate adjusting system for burners - has ceramic oxygen sensor in flue for controlling air blower
Inventor: HEIMKE GUENTHER DIPL PHYS DR
IPC: F23N5/24
Filed: 1975-03-08
Abstract: System for controlling gas, oil or pulverised coal burners is adapted to given loading conditions by changing the flow rate of the fuel, simplifies the control of the fuel and air ratio and reduces the delay period in the adjustment of optimum combustion conditions. The air supply is controlled by a solid electrolytic oxygen detector (7) which is fitted into the flue gas channel (6).
