Abstract: 1,209,773. Wall facing. KRONE K.G. 3 Nov., 1967 [3 Now, 1966], No. 50046/67. Heading E1W. The space between a wall 1 and a panelled facing is sealed, as at 10, along the upper and lateral margins and around window openings in the wall 1, at least one opening 12 being provided between the lower marginal portions of the facing and the wall to maintain communication between the space and the outer atmosphere. The panels 7, each of which comprises a heat insulating core 7a having a structurally strong watertight covering 7b at least over its outer and edge faces, have sealing means 10 therebetween which may be formed of soft elastic material covered by a separate or integrally formed weather resistant strip 11.

Abstract: 1374239 Electric analogue calculating NATIONAL RESEARCH DEVELOPMENT CORP 21 Oct 1971 [21 Oct 1970] 50072/70 Heading G4G An electric analogue calculating circuit intended for calculations concerned with processes such as sterilizing foods, comprises a multivibrator circuit 1 generating a ramp waveform reference signal which is taken via transistor T 3  to a comparator 2 which has as its other input a signal T A  representing the temperature of the process. The output of the comparator is a series of pulses of duration dependent on the difference between its two inputs. The pulses are amplified in an amplifier 3 and integrated in an RC network 4. The integrated signal is then detected by a circuit 5 including a diode D 3  and the required output is taken from the emitter of transistor T 9 .

Title: Colour Display Cathode Ray Tube Display Screens.
IPC: H01J9/227
Filed: 1967-11-03
Abstract: 1,156,077. Automatic light intensity control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov.3, 1967 [Nov. 8, 1966], No.50105/67. Heading G3R. [Also in Division H1] A multi-colour cathode-ray tube is manufactured by passing light from a source through a perforated shadow mask to fix luminescent material of each colour, a photo-cell responsive to light from the source controlling the energy supplied to the source to maintain light intensity constant. The screen of the tube is moved from one to the other of a number of operating stations. At each station a layer of luminescent material of a different colour is applied together with a photo-sensitive lacquer which fixes the material to form dots where it is exposed to light from a discharge lamp passing through a suitably perforated shadow mask which may be that finally used in the tube. The unfixed material is then washed off before passing the screen to the next station at which a further pattern of dots, displaced from the first and corresponding to a different colour, is produced. In Fig. 2, the voltage output of a photo-cell 12 responsive to light from a HPMV discharge lamp 7 at a typical station is compared with a reference voltage from a potentiometer 31 so that any difference is effective through a transistor amplifier 29 to operate a motor 30 adjusting the tapping 24 of a lamp supply transformer 23 in the appropriate direction to maintain constant light output from lamp 7. The lamp is switched on by a self-holding manually-operated push button switch 44 which remains on until a clock 43 releases a pin 40 after a time suited to the colour. When the reading of a voltmeter 45 exceeds a predetermined value, lamp 7 needs replacing. Operation of the lamp above its rating because of its intermittent use is referred to.

Abstract: 1,260,862. Fluid-pressure operated motors. TELEKTRON Ltd. March 19, 1969 [March 26, 1968; Oct. 30, 1968], Nos. 14524/68 and 51523/68. Headings F1A and F1M. A reciprocating fluid operated diaphram motor, has a thrust diaphram 14 which is adapted for connection to a driven member 19 and is peripherally held at one end 13 of a housing containing a valve assembly and is biassed towards the rear end of the valve assembly housing by a bias member 17. The valve assembly comprises a supply port 28 for the supply of pressure fluid to the rear side of the thrust diaphram to drive it forwardly and an exhaust port 29 for releasing pressure from the rear side of the thrust diaphram. The assembly also includes a supply valve 2A, 24A comprising a rear valve member 2A suspended by a rear diaphram 7 and a co-operating valve member 24A suspended by an intermediate diaphram 6 the diaphrams defining between them a pressure space permanently communicating with the supply port and means biassing at least one of the valve members to an open position in which the pressure space communicates with the rear of the thrust diaphram. An exhaust valve 13B, 23B has an exhaust valve member 23B suspended by the intermediate diaphram and resiliently biased to a closed position in which it isolates the thrust diaphram 14 from the exhaust port 29. Coupling means 22B, 20A acts between the thrust diaphram and the rear member of the supply valve. The arrangement is such that, in operation, the thrust diaphram is driven forwardly to move the rear valve member 2A into sealing engagement with its co-operating valve member to isolate the thrust diaphram from the supply port, whereafter supply pressure acting on the intermediate diaphram urges the latter forwardly until the exhaust valve member 23B is lifted from its seat to exhaust the pressure from the thrust diaphram where upon the latter is driven rearwardly by its bias member permitting the exhaust valve to reclose and the supply valve to reopen. The motor may be pneumatically or hydraulically operated.

In apparatus for coating the interior of pipes, cold setting resin and a liquid curing agent are supplied through respective pipes from a device comprising two positive displacement piston pumps for the respective liquids, the swept volumes of the two pumps being in the same proportions as the proportions in which the liquids are required to be mixed; means for driving the pumps at the same rate including a pneumatic ram, and the arrangement being such that if the driving means fail both pumps stop simultaneously. A double-acting pneumatic ram 14 directly drives two piston pumps 10 and 12, the piston areas of which are in the same proportions as the proportions in which the respective liquids are to be mixed. The pumps are connected to respective supply tanks 16 and 18 disposed one above the other and having capacities substantially in the ratio in which the liquids are required to be mixed. The air pressure to ram 14 can be varied to control the pumping speed. The air pressure may be increased to operate the ram at a speed producing a higher rate of delivery than is required, and limit switches are provided to stop the ram after a single or a double stroke, a timer also being provided to re-start the ram at predetermined intervals of time in accordance with the pumping rate required.
