Filed: 1974-07-18
Abstract: 1511845 Solid electrolyte oxygen sensor GEORGE KENT Ltd 18 July 1975 [18 July 1974] 31940/74 Heading G1N A solid electrolyte sensor for measuring oxygen in gases comprises a tube of solid electrolyte closed at one end, electrodes, one inside and one outside the tube arranged at or near the closed end, a furnace surrounding the closed end, a reference gas supply to the interior electrode and a sealing material separating the reference gas supply from the outside of the closed end and having holes outside the furnace so that the sealing material cannot conduct reference gas to the outside electrode. The sensor is designed for measuring oxygen content of flue gases the tube of zirconia (optionally with calcia, yttria or magnesia) or of yttriathoria is maintained at about 700‹C by the furnace and a thermocouple 65. The solid electrolyte tube 1 has platinum electrodes 11 mounted on the closed end and is surrounded except at its ends by stainless steel supporting tube 13, the space between them being filled by insulating sealing material 17a, 17b. The closed end of the solid electrolyte tube is covered by a cap 19 with ports 21. Heater 27 and associated insulation 31 surrounds the electrode end of tube 1 and the heater assembly is enclosed by dust filter 33. Reference gas supply is via chamber 39. Reference gas is supplied via tube 51 to connector 55 and thence via tube 57 to the inner electrode. The gas returns between tubes 57 and 1, passes into chamber 39 then down the annular passage between tube 51 and tube 5, the tube 5 supporting the whole assembly. To prevent conduction of reference gas from chamber 39 to the outside of sensor 1 via the sealing layer 17, both stainless steel tube 13 and sealing layer 17 have apertures 15 open to flue gases in the region between chamber 39 and filter chamber 33, so that gas in sealing layer 17a is swept away and both ends of sealing layer 176 are subjected to the gas concentration to be measured.

Abstract: 635,829. Radiolocation. SPERRY GYROSCOPE CO., Inc. Nov. 6, 1946, No. 32988. Convention date, March 9, 1943. Addition to 616,520. [Class 40 (vii)] In a radar system producing a stereoscopic display of viewed objects, range-marking indications are introduced into the display. In the system shown, which is similar to that in the parent Specification, reflected pulses from a scanner 15 are displayed on two cathode-ray tubes 21, 89 viewed separately through polarizing screens 91, 92, the beams being.scanned horizontally and vertically by circuits 24, 23 synchronized with the scanner, and the horizontal positions being further displaced in opposite directions by a saw-tooth generator 37 to a varying distance corresponding to range. A further cathode-ray tube 97 has a constant-intensity beam scanning a target 103 having markings corresponding to range figures or graduations which markings have a different secondary-emission ratio, e.g. carbon ink on aluminium foil with an oxide coating. The beam is scanned horizontally by a saw-tooth generator 101 and vertically by a generator 104 synchronized with the scanning cycle to produce signals corresponding to the markings on target 103. At an instant in each scanning cycle, these signals are supplied over commutator 86 to the indicator tubes 21, 89 and at the same time receiver 17 and transmitter 13 are disconnected and generators 101, 104 are connected to the indicator tubes instead of circuits 24, 23. If switches 102, 105, 107 are moved to the dotted-line positions, tube 97 is disconnected and a series of marker dots is produced by a pulse-generator 113 connected to a frequency-multiplier 112, the dots being extended into lines by generator 104. In a modification, Fig. 8 (not shown), during the marker-generating interval, pulses derived from a phase-shifted version of the control frequency are applied to the indicator tubes and amplifiers 63, 64 are connected in series with circuits 23, 24. These amplifiers are adjustable as to amplitude by knobs 65, 67 and as to position of trace by knobs 66, 68 so that, for example, the pulses may be caused to form a small circle which may be located around a particular image. The phase-shifter is then adjusted so that the circle appears to be in the same plane as the image when the reading of the phase-shifter will give a measure of range. The knobs 66, 68 may also be calibrated to give angular position. Specifications 627,012 and 635,821 are referred to.
