Abstract: 904,552. Igniting burners. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 28, 1959 [July 29, 1958], No. 25922/59. Class 75 (3). [Also in Groups XII and XXVI] In combustion equipment such as main or reheat combustion equipment of a jet propulsion unit comprising a chamber through which a mixture of fuel and air flows, means are provided for effecting ignition or for improving combustion of the mixture by creating in the flow path of the mixture an intense electric field producing ionizing discharges, by the application of a high voltage between one or a plurality of pairs of electrodes oppositely disposed radially of the combustion chamber, the spacing of the electrodes of each pair and the applied voltage being such that no sparking occurs. In Fig. 2 a pair of oppositely-disposed electrodes 1 and 2 is disposed downstream of a flame-holder device 3 having a fuel injector nozzle 5 centrally disposed therein, the electrodes being connected to a source 4 of alternating high voltage. The ends of the electrodes are pointed so as to ensure ignition of the fuel and air mixture. In Fig. 5 a second pair of electrodes 6, 7 in the form of plates is disposed downstream of the pointed electrodes, all four electrodes being supplied from the same source and so connected that at any instant, the pointed electrode and the plate at the same side have the same polarity; alternatively the connections may be made so that the pointed electrode and the plate at the same side have opposite polarity as in Fig. 7. The voltage applied to the electrodes 1, 2, 6 and 7 is taken from an alternator 4 through a regulator 8 and transformer 9, the alternator supplying, say, 120 volts, three phase, 400 cycles, and the output of the transformer being at, say, 20 kilovolts. The voltage applied to the electrodes may be regulated in dependence on delivery pressure of the engine compressor, the fuel-toair ratio of the mixture, the altitude of the aircraft or the temperature of the combustion gases. Fluid type flame stabilizer screens may be used in place of solid type.

Title: Improvements in or relating to spray guns for spraying paint or the like medium by means of compressed air
IPC: B05B7/24
Filed: 1954-09-08
Abstract: <PICT:0765368/III/1> A spray gun for spraying paint or the like medium has passages in the gun body for compressed air and the medium to be sprayed respectively the passages communicating with one another and through a common outlet with a mixing chamber in the gun body having an outlet in communication with the spray nozzle of the gun.  Compressed air flows through a pipe 17 in the handle of a spray gun to a trigger operated valve 15 then to a passage 16 communicating with a passage 18 in the gun body 10.  A part 181 of the passage 18 inclines upwardly to a mixing chamber 19.  A pipe 12 leads from a liquid container to the passage 181 and a pipe extends from the passage 18 above the surface of the liquid in the container.  Valves 20, 23 control the flow of compressed air and liquid.  A needle valve 22 closes the nozzle aperture.  A trigger 14, when pressed, opens the compressed air valve first and the needle valve second.  In a modification the compressed air and liquid supply passages are contained in a lid fitting over the top of the container 11.  In a similar construction the pipe 12 leads into a transverse bore which communicates with the passage 181.  A protective vessel surrounds the container and has a handle and may have heating means.

Title: Photographic camera
Inventor: ORT WOLFGANG
IPC: G03B7/085
Filed: 1968-05-30
Abstract: 1,224,545. Photographic camera exposure control. EASTMAN KODAK CO. May.30, 1968 [May 30, 1967], No.26053/68. Heading G2A. A photographic camera comprises two slidably mounted diaphragm plates 10, 11 movable in parallel planes in opposite directions by means of a pair of pins 8, 9 engaging slots in the plates and carried by a rotatable disc 4 equidistantly from the centre thereof, a mechanically driven shutter 23, and electromagnet 21 which is controlled by the amplified output of a photo-resistor 20 subjected to scene light and which, in daylight operation of the camera, automatically regulates the movement of the diaphragm plates and thereafter releases the shutter to provide one shutter speed and, in flash operation of the camera, means for adjusting the diaphragm plates independently of the output of the photo-resistor and an RC circuit member which in the flash range is connected in the photo-resistor circuit to retard the shutter speed. The diaphragm plates have co-operating exposure apertures 12, 13 and further co-operating apertures 16, 17 disposed in the light path 19 to the photo-resister 20. In daylight operation, actuation of lever 1 in the direction of arrow A allows ratchet wheel 4 to rotate thus opening the exposure aperture and at the same time the metering aperture. Upon the illumination of photo-resistor 20 reaching a certain level, a transistor relay circuit fires to actuate electromagnet 21 whose armature 22 engages in the teeth of ratchet wheel 4 and thus holds the exposure aperture constant, and at the same time allows shutter 23 to slide in a direction B under the action of a spring 24 through projections 25, 26. For flash operation, the exposure aperture is manually set, e. g. by coupling with the camera range setter, and the shutter opened by a force in direction A<SP>1</SP> freeing projection 25. A projection 30 on the shutter operates a switch 31 to fire the flash-bulb and a further projection 28 operates a changeover switch 29 in the transistor circuit which commences an RC timing circuit to charge. After a predetermined interval, e.g. 1/30th sec, the timing circuit triggers the transistor relay circuit to actuate the electromagnet whose armature is pulled clear of projection 26 to allow the shutter to close. If in the daylight mode, insufficient ambient illumination is available, an optical signal is given in the view-finder, e.g. mechanically, by the complete travel of the sliding diaphragm, and the shutter is not operated.

Title: Television receiver

Filed: 1971-04-19
Abstract: 1352038 Television; multiplex radio signalling MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 April 1971 [8 April 1970 (2)] 26133/71 Headings H4F and H4L A television receiver receives a video signal comprising two sets of video signals transmitted in a line sequential manner and an audio signal on a carrier, the audio signal comprising one audio signal and a second audio signal on a subcarrier, the audio signals being reproduced at loud-speakers 11, 13, Fig. 1, respectively. The video signal is fed from a detector 3 to a switching circuit 22 where the sets of video signals are separated, one set of signals being fed to output circuit 18 and the other to output circuit 19. Each output circuit 18, 19 has associated with it a one-line delay line 20, 21 so that each line of received information is displayed on two adjacent lines on the respective cathoderay tube 14, 15. The switching circuit 22 comprises a bi-stable multivibrator 44, Fig. 2, operated by the horizontal synchronizing pulses from a synchronization separator 5 via transistors 34, 40. The output of multivibrator 44 is fed via phase-splitting transistor 48 to alternately switch on and off transistors 56 and 64 which feed the signals from detector 3 to the output circuits 18 and 19. During the vertical blanking period the vertical synchronizing signals from separator 5 are integrated by resistor 69 and capacitor 70. When the integrated signal reaches a predetermined value transistor 81 is cut off and the collector voltage of transistor 81 rises, and triggers a monostable multivibrator 86. The output from the multivibrator 86 is passed to a multivibrator circuit 88 which includes a transistor which is cut off by this output, so cutting off the power supply to multivibrator 44 for a predetermined period. The output from the multivibrator 86 also cuts off transistor 40 for a longer period, so that the output of multivibrator 44 is zero during part of the vertical blanking period, the transistor 56 being biased on and transistor 64 off. The first horizontal synchronizing pulse from separator 5 after the pulse from multivibrator 86 finishes thus causes transistor 64 to be turned on and transistor 56 off, so that during every frame the correct set of signals is supplied to the correct output circuit 18 or 19, as the first line of each frame is a line of a specified one of the two sets of video signals.
