Patent GB-1051108-A (GB)
IPC: G01N31/22
Abstract: 1,051,108. Gas analysis. MINE SAFETY APPLIANCES CO. Oct.13, 1965 [Oct.15, 1964], No. 43420/65. Heading G1B. Chlorine dioxide in a gas is determined by passing the gas through an inert granular solid, e.g. silica gel, containing N, N, N<SP>1</SP>, N<SP>1</SP> tetraphenyl benzidine, the solid being contained in a transparent tube and changing to a tan colour in contact with chlorine dioxide. The concentration of chlorine dioxide may be determined if the volume of gas passed through the tube is known and the length of stain is measured. Since this reagent turns blue in the presence of chlorine, chlorine and chlorine dioxide can be estimated simultaneously by measuring the lengths of the blue and tan stains. The reagent may tend to develop a blue colour on storage but this may be inhibited by the inclusion of alkaline pyrogallol a manganous oxide.

Abstract: 1,226,823. 823. Infrared absorption analysis. ATOMIC ENERGY OF CANADA Ltd. June 18, 1968 [June 21, 1967], No.28905/68. Heading G1A. [Also in Divisions B1 and B2] Samples of water to be tested and of reference water are selectively delivered to an isotopic purity measuring device, for example an infrared absorption device using a sample delivery system comprising a supply of reference water for reservoirs R 1 , R 2 , at least two supplies of samples to be tested for reservoirs S i  - - S 5  and means for storing the reference and test samples and delivering a selected one to the measuring device 29 and comprising an equilibration tubing 28 Fig. 2 passing through a controlled temperature bath for equalizing the temperatures of the reference water and the test samples, the sample delivery system being adapted for connection to a single source 30 of constant pneumatic pressure for driving the selected sample to the measuring device. Reference water reservoirs R 1  and R 2  are alternately filled from source 16 and emptied by applying air pressure through line 33 to force the reference water through valve 40, tubing 28 and line 45 to the measuring device 29. Similarly samples from reservoirs S 1  to S 4  are fed successively through line 26 or 27 to measuring device 29, one sample flowing through one of the lines 26, 27 and through tubing 28 to waste, to purge the tubing from the preceding sample from that line, while another sample flows through the other of lines 26, 27 to device 29. While the reservoirs are being filled their upper ends may be open to atmosphere or to for example an aspirator to remove dissolved air. Reservoir S 5  has separate filling lines (50, 51) and emptying lines (52, 26) to prevent any air-bubbles reaching the output line.

Abstract: 1,231,158. Cathode-ray storage tubes. HITACHI Ltd. 30 June, 1969 [1 July, 1968], No. 33022/69. Heading H1D. [Also in Division H4] To improve the contrast in a picture obtained by photographing the fluorescent screen of a direct-view type storage tube by compensating for the saturation characteristic in the brightness of the image on the screen related to the stored charge-density on the target, the bias voltage applied to the target is changed in a continuous manner (e.g. sawtooth, quadratic or exponential) or stepped manner over a range between one value at which none of the stored charge-density pattern is reproduced on the screen and another value at which the whole of the pattern is reproduced, so that the amount of exposure of the photographic film is increased in areas of the pattern where the stored charge density is highest. In an embodiment of the invention gamma rays from a gamma-ray source (isotope) to be photographed are received by a scintillator 3, Fig. 1, and converted by phototubes 4 into electric signals which are proportional to thedensity distribution of the gamma ray source. These signals are fed to a computing circuit 5 which derives pulse signals I (intensity modulation signal) and V x  and V y  (deflecting voltages) and then stored in the form of a charge-density pattern on the surface of the storage target of direct-view type storage tube 6, Fig. 2. Tube 6 comprises recording, reproducing and erasing guns 62, 63 and 64 respectively, collector screen 67, anode 68, fluorescent screen 65 and storage target 66 of nickel mesh coated with calcium fluoride. To display the stored pattern on the fluorescent screen of the tube the flood beam e r  from reproducing gun 63 is utilized, but due to the saturation characteristic of the tube, Fig. 3, the resulting visible image does not accurately correspond to the density distribution of the gamma ray source i.e. the chargedensity pattern, and thus it is not possible to distinguish in the image density changes of the gamma ray source where the gamma ray intensity is high. To compensate for this characteristic and thus improve the contrast of the picture the target bias voltage is changed in a continuous or stepped manner from a low voltage e 0 , Fig. 4, for example, in which none of the charge pattern is displayed, through the voltages e 1  to e n  for which the highest charge pattern area S1 and S2 are displayed, voltage e 2 , and so on until the whole charge pattern is displayed. Throughout this sequence the shutter 73 of the photographic camera viewing the screen of tube is kept released so that an increased amount of exposure is obtained for the higher brightness area. The stored charge density pattern may be repeatedly reproduced e.g. for further photographing, and since the image is visible on the screen contrast adjustments may be made before it is photographed.

Abstract: 1,250,687. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 2 Oct., 1969 [7 Oct., 1968], No. 48444/69. Heading G6C. A fuel element can is provided with a diffusion barrier consisting of a suspension of graphite in nitrocellulose by applying a suspension of graphite in a nitrocellulose solution to that surface of the can which is intended to come into contact with the fuel, and heating the can so coated to a temperature high enough to eliminate the nitrocellulose solvent. The fuel may be U or U-alloy in a can of Mg or Mg-alloy, or a U-oxide based ceramic fuel in a can of Zr or Zr-alloy. The barrier serves to prevent diffusion of Pu and fission products which form during irradiation of the fuel through the can at operating temperatures. In the case of U-oxide fuel, the barrier also prevents diffusion of O 2  from the fuel into the can. In a particular example, a suspension was prepared from 150 g. colloidal graphite/litre of a solution containing 45 c.c. nitrocellulose, 25 c.c. butyl alcohol and 930 c.c. butyl acetate. This suspension was used to coat the interior of a Zr-1À5 wt. per cent Cu alloy fuel can by being passed through the can four times, each followed by air-drying. The can coated in this way was heated in a vacuum of 10<SP>-5</SP> Torr at 400 C. for 2 hours. This process gave a barrier having a total thickness of 15 microns. The diffusion barrier may alternatively be deposited on the outer surface of the fuel.

Abstract: 1,258,865. Programme control. FUJITSU Ltd. May 13, 1970 [May 14, 1969], No.23090/70. Heading G3N. A digitally controlled electrohydraulic drive incorporates a compensating electric pulse motor, responsive to signals representative of machine error, driving a differential mechanism, in the control of a valve for the hydraulic motor, so as to lend to eliminate the error. As shown, a train of command pulses from a digital controller 1 are fed to an electric pulse motor 4 driving a gear 13 of a differential mechanism 10. The output shaft 9 of the mechanism drives a rotatable spool of an hydraulic valve 5, axially movable by a screw- and-nut device, supplying an hydraulic motor 6 positioning, through fearing 17, 18 and lead-screw 19 a slide 20 of a machine. The rotation of the motor 6 tends to restore the position of the spool to fluid cut-off by the nut being attached to the rotor of motor 6 and the screw being attached to the spool of the valve. Positional error of the slide is corrected by an electric pulse motor 7 driving a gear 15 of the differential mechanism, energized through a gate 32, 33 from a pulse oscillator 34. The error e of the machine system is derived from the command valve c, a compensation valve c<SP>1</SP> fed to the motor 7, and delay d. A sinusoidal valve corresponding to the actual movement c + c<SP>1</SP> - d + e is derived from a linear winding 21 of a positional transducer 23 coupled to the machine 20 and fed to a phase discriminator 31. The motor 6 drives a resolver 27 having outputs, as shown, which are fed to a differential resolver 30 driven by the pulse motor 7, providing a sinusoidal output, dependent on command movement and delay c-d, which is fed to the discriminator 31. The output of the phase discriminator 31, representative of the compensation value and error c<SP>1</SP>, e, is fed to open the positive gate 32, or negative gate 32 in dependence on the sign of the output and the value being above a threshold value, to pass compensation pulses c<SP>1</SP> to the pulse motor 1 from the oscillator 34.
