Abstract: 699,262. Separation of gases. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. April 23, 1951 [April 26, 1950], No. 9378/51. Class 8 (ii). Compressed gas is cooled and liquefied by first cooling in a heat exchanger 2 Fig. 1 and then cooling by means of a cold-gas cooling machine 4 operating on the reversed hot-gas reciprocating engine principle, the liquid thus formed being subsequently expanded at a nozzle 6; the unliquefied gas serves to cool the exchanger 2. A second heat exchanger 5 is traversed by the gas and liquid mixture leaving the machine 4, and this is also cooled by the expanded gas. As applied to an air separating process, compressed air is cooled by a counter current heat exchanger 32 Fig. 3, a machine 33 corresponding to the machine 4, and a second exchanger 34, and the gas and liquid mixture after traversing an oxygen boiling coil 38 in a reservoir 37 is expanded at a valve 40 before entering the separating column 36 from the head of which nitrogen gas leaves by an outlet 44, and from the base liquid oxygen by an outlet 45. Both constituents serve to cool the exchangers 32, 34. The pressure of the gas is constant during cooling and does not exceed its critical value, and is cooled to a temperature adjacent the point of intersection of the pressure line and the limiting line within the critical range at which the gas liquefies.

Title: Process for the conversion to sulphur and/or sulphur dioxide of other sulphur compounds and catalysts therefor
IPC: C10K1/34
Filed: 1947-04-09
Abstract: Sulphur and/or sulphur dioxide are produced by passing hydrogen sulphide, carbon disulphide, carboxysulphide and mercaptans (according to the catalyst used to effect oxidation thereof) in the gaseous state and oxygen, carbon-monoxide or carbon dioxide at, say, 80-400 DEG  C. into contact with a catalyst comprising an admixture upon a carrier of at least one alkali sulphide and nickel, cobalt, manganese, cadmium, tin or aluminium sulphide or sulphides.  Where industrial gases are used, such as town-gas, coke-oven gas or blue-water-gas, containing the sulphur compound and one or more of the gases oxygen, carbon monoxide and carbon dioxide, but free from cyanide compounds, tar fog or heavy petroleum fog, the oxygen-containing gases need not be added. According to one example, the gases, after the catalytic oxidation, are scrubbed with water and sulphur recovered by filtration.  The catalyst may be made separately or in situ by passing, say, hydrogen, carbon monoxide or water-gas and a sulphide, e.g. one or more of the above-mentioned sulphur compounds into contact at about 240 DEG  C. with a mixture of at least one alkali compound and a reducible compound or compounds of one or more of the metals upon a catalyst carrier.  Thus the catalyst may be made (1) by mixing a molten compound of the metal with an inert carrier to form a stiff paste, immersing the paste after baking in a strong solution of an alkali carbonate, bicarbonate, sulphite or sulphide, baking and granulating to pellets, and treating the pellets at about 240 DEG  C. with a mixture of hydrogen sulphide and a reducing gas; (2) by dry mixing and grinding the alkali compound(s), metal compound(s), especially oxides such as manganese dioxide and bauxite, the latter requiring no carrier, and inert catalyst carrier together, mixing to a paste with a solvent, e.g. water, for the alkali compound, drying, granulating and reducing as above; and (3) by immersing the catalyst carrier in pellet form in a solution of a reducible compound of one of the metals until saturated, drying the pellets, immersing them in a solution of an alkali carbonate &c. until saturated and reducing as above.  Carriers specified are diatomaceous earth, kieselguhr, pumice, activated charcoal and silica gels.

Abstract: 1,221,823. Luminescent materials and uses thereof. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 27 Feb., 1968 [29 June, 1967; 28 Dec., 1967 (3)], No. 9492/68. Heading C4S. A thermoluminescent phosphor in a thermoluminescent radiation dosimeter for instance, comprises calcium sulphate as the principal constituent and at least one activator selected from Dy, Tm, Tb, and Pr and in amount 0À005 to 0À5 mol. per cent for instance. Triboluminescence is almost absent. The phosphor may be encapsulated as powder (e.g. 10 to 150 micron size) in polyethylene, fluorine resin or glass (Figs. 4 and 5, not shown) and in an Al container. Glasses should be non-fluorescent and of low melting point and boron, zinc oxide or lead oxide types only, the capsules being 0À2 to 0À5 mm. deep and the mix hot-pressed at 500‹ to 600‹ C. In the case of lead glass, the element should be as thin as 0À5 mm. to reduce radio-active radiation absorption. Resins should be heat-resistant at 300‹ C. or more and very transparent to U.V. and visible radiation; epoxy resins fluorescing at 100‹ C. or above and silicon resins being of low viscosity at high temperature are not suitable. Fluorine resins are preferred and include poly-tetra-fluoroethylene, the copolymer of tetra-fluoro-ethylene and hexa-fluoro-propylene poly-monochloro-trifluoro-ethylene, and poly-hexa-fluoro-ethylene and the mix may be cold-pressed at 280‹ to 420‹ C. The CaSO 4  crystallites are 0À01 to 0À3 mm. in grading and mixtures are equal parts by weight phosphor and encapsulating medium. In preparing the phosphor, calcium sulphate and the activators are added to hot concentrated sulphuric acid and the sulphuric acid is vaporized to recrystallize the sulphate. Doses specified are of visible and U.V. light, radio-active emanations and electrons. The main glow peaks and secondary peaks at specific temperatures are given for particular embodiments, e.g. for CaSO 4  : Dy heated at 30‹ C./min., the peak occurs at 210‹ C. and accumulated absorbed radiation may be removed by heating at 400‹ to 700‹ C. CaSO 4  : Tm peaks at 215‹ C. with a secondary peak at 100‹ C. Applications to health physics and measurements of small doses are mentioned. Reference is made to prior art CaF 2 [Mn]; CaSO 4 [Mn] and LiF phosphors.

Abstract: 171,940. M³ller, H. March 30, 1921. Aninimals.-A toy animal or figure has its head supported in such a manner that it can be turned in any direction without friction between it and the body. The stuffed figure, shown in Fig. 1, has the body closed at the neck by a dished plate b. A tube c, rotatably connected to the plate b, projects through a slot in a similar plate K which closes the lower ends of a casing h inserted in the head. The head is mounted on an axle i passing through the tube c and is thus free to move without contact between the plates band k. A rod f, passing through the tube and projecting through a slot, is connected by a pin o to the casing h and also to the tail of the figure, so that the head can bemoved in any direction by means of the tail. The body a is made of cloth and is secured to the plateb by means of pointed projections l, Fig. 4, which are passed through the cloth and are then bent down. Thus the body can be stuffed through the neck and the stitching of all the seams of thecloth is concealed.

Title: Improvements in or relating to thermionic valve circuits
Inventor: COOKE-YARBOROUGH EDMUND HARRY
IPC: H03K3/10
Filed: 1948-04-06
Abstract: 647,598. Pulse lengthening circuits. MINISTER OF SUPPLY. April 6, 1948, No. 9564. [Class 40 (vi)] The Figure shows a flip-flop circuit in which valve 1 is normally cut-off and valve 2 conducting the cathode follower valve 8 acting as a buffer stage. When a negative triggering pulse is applied at the input 18 the current flow in valve 2 is reduced and the rise in its anode potential is applied via valve 8 to the screengrid of valve 1. The screen-grid and control grid of valve 1 in the cut-off condition have a potential close to that of their cathode so that when the screen-grid potential is increased the current through the valve rapidly increases and the circuit is tripped to the unstable condition with valve 2 cut-off and valve 1 conducting. After a period determined by the time constant of network 3, 15 the charge on capacitor 3 leaks away until valve 2 is rendered conducting, the screen-grid voltage of valve 1 decreases and the circuit reverts to its initial stable condition. The restoration to the stable state is made more rapid by the low resistance leakage path for capacitor 3 which is provided by diode 16. The circuit is stabilized and rendered less affected by change in valve characteristics &c. by the application of negative feed-back over valve 1 via resistor 6 and over valve 2 via resistor 11, the cathode follower stage 8 and resistor 14. The sensitivity of the circuit may be adjusted by the setting of potentiometer 9. The circuit may be used to produce an output pulse at terminal 20 of large amplitude and long duration from an input pulse of small amplitude and short duration.
