Title: Improvements in or relating to mortar projectiles
IPC: F42B14/06
Filed: 1953-08-11
Abstract: 737,348. Ammunition projectiles. DONNER, H. O. Aug. 11, 1953 [April 18, 1953], No. 22161/53. Class 9(1). A fin-stabilised projectile for discharge from smooth bore mortars has a metal body 1 filled with explosive to be ignited by a nose fuze 2 and a tail 3 supporting fins 4 and closed by a thrust member 5. The member 5, which accommodates a propellant cartridge, has radial passages 8 aligned with openings 81 in an obturating member 9, which is arranged to transmit the propellant thrust to the member 5. Fitted into the rear of the thrust member is an element 7 which houses the igniter for the propellant and is surrounded by an extension 91 of the obturator. The maximum diameter of the obturator is greater than the overall diameter of the fins and has grooves 12 separating bearing surfaces 11 which engage the bore of the mortar. Gas accumulating in the annular chamber 10 within the extension forces the obturator away from the projectile after it leaves the barrel.

Abstract: 841,136. Sensitive materials for colour photography. KODAK Ltd. (Eastman Kodak Co.). Aug. 7, 1956 [Aug. 4, 1955; Dec. 20, 1955], Nos. 22410/55 and 36557/55. Class 98(2) A silver halide emulsion contains a colour coupler and a composition obtained by polymerizing 95À5% of at least one inonoethylenically-unsaturated compound containing a - CH=C< group with 5À95% of an unsubstituted protein or an acylated protein; i.e. a graft polymer, which may be made by the methods of Specifications. 796,401 or 807,894. Many methods of preparing the final materials are described, in most of which gelatin is present as an additional constituent; thus a coupler dispersion in aqueous gelatin may be mixed with a dispersion of the polymer and gelatin silver halide emulsion (Examples 1, 2), or with a silver halide emulsion in a vehicle of gelatin and polymer (Examples 3-6); or coupler in polymer may be added to a gelatin silver halide emulsion or a polymer-silver halide emulsion (Examples 7-10). Example 11 illustrates formation of a coupler dispersion in a high boiling solvent and incorporation of polymer and gelatin silver halide emulsion therewith. As detailed in Example 1 the coupler 1-(2<1>,4<1>,6 1-trichlorophenyl)- 3- [3<11>- (2<111>,4<111>-di-tert-amylphenoxyacetamido) - benzamido] - 5 - pyrazolone of Specification 680,488 dissolved in hot ethyl acetate is emulsified in aqueous gelatin solution containing alkylnaphthalene sodium sulphonate and the product noodled and dried; for the polymer and as in the method of Specification 796,401, n-butyl acrylate, acrylonitrile, and succinyl glue as of Specifications 648,927 and 649,544 are heated with aqueous potassium persulphate, and the resulting hydrosol and the redispersed coupler emulsion are added to a gelatine-silver halide emulsion, and the product is coated, exposed and colour developed to give a dye image. Included in Example 11 is the preparation of a coupler dispersion in the high boiling solvent di-n-butyl phthalate with gelatin, and the addition of this to a polymer made from glue, n-butyl acrylate and styrene, and the gelatin silver halide emulsion. Tables comparing speed, density, gamma and fog of the materials of some of the examples with similar materials made without the polymer are provided.

Title: Improvements in dehydrating units intended particularly for drying heat insulation by air circulation
IPC: B01D53/26
Filed: 1951-09-26
Abstract: 707,093. Drying air. AMERICAN W.M.B., Inc. Sept. 26, 1951 [Sept. 26, 1950], No. 22482/51. Class 34(1) Apparatus for drying air which has circulated through the insulation of cold storage chambers, has a container 16 wherein the moist air passes through a layer of adsorbent material 62 such as alumina which is regenerated at intervals by supplying heat thereto, the surface of the layer being swept over by heated air, and the conduit system communicating with the layer is arranged to create a natural circulation of heated air in a closed circuit to remove the moisture expelled by the heating. The apparatus has' an exterior casing 10 and an interior casing 12 between which is a layer of rock wool 14, the inner casing being divided into two chambers 18, 20 by the container 16. Air to be dried enters by pipe socket 22 and leaves by socket 24, which sockets extend through sockets 28. 30 the space between being filled with a layer 31 of sponge rubber. Each of the sockets 22, 24 communicates with an L- shaped channel 32, 34 having branches each merging into a vertical channel 36, 38 separated by a partition 40 having an ori fice 42 for a flap valve 44 pivotally mounted on a pin 46 and carrying a weight 48 tending to turn it to a position cutting off communication between the interior of the apparatus and sockets 22, 24. Hoods 50, 52 above channels 36, 38 prevent condensation water from running into the channels and direct it to drain conduits 56 discharging into the lower part of casing 12. Container 16 comprises two U-shaped bars 58 carrying gauze filters 60 which contain the alumina, electric heaters 63 being located within the adsorbent. Packing elements 70 between the bars 58 of the frame and an extension 74 of partition 40 separate the chambers 18, 20 from one another so that the air must pass through the adsorbent 62. Pipes 78 extending along the interior vertical faces of the outer casing 10 communicate with horizontally extending pipes 80 having branch pipes 82 entering the upper parts of chambers 18, 20 respectively and similar horizontal pipes 84 and connection pipes 86 communicate with the lower part of the chambers and pipes 78. A discharge pipe 88 shaped as a drain trap extends from each pipe 84 and merges into a common pipe 90 extending out of the casing. During drying of the air valve 44 is in sealing contact with the edges of opening 42 as pressure in channel 36 is higher than that in channel 38 but when regeneration takes place the air flow is cut off by a time switch which also closes the circuit to heaters 63 and valve 44 closes under weight 48 to seal the conduits leading from chambers 18, 20. Since pipes 78 have a lower temperature than the chambers 18, 20 a natural circulation takes place and also pipes 78 act as condensers, the condensate being collected in the traps 88 and discharged through pipe 90. A thermostat 96 secured to the inner casing 12 interrupts the regeneration when the adsorbent reaches a predetermined value such as 150‹C.

Title: Hydraulic systems
IPC: F15B13/04
Filed: 1973-05-15
Abstract: 1452609 Hydraulic control circuits SPERRY RAND Ltd 29 April 1974 [15 May 1973] 22950/73 Heading F1P [Also in Division F2] In the circuit shown, Fig.1, in which a valve 1 controls supply and exhaust of hydraulic liquid to and from a load 2, a compensator, connected between the service ports 6, 7 of the valve and the load, restricts the flow in the service lines so as to maintain a constant pressure difference between the supply pressure and the pressure at the service port supplying the load. In operation, a spring 23 in the compensator is set so as to correspond to the pressure to be dropped across the valve 1, e.g. 125 lbs. per sq.in. If the valve 1 is moved to the left in Fig.1, pilot pressure in the valve also operates a shuttle valve 22 connecting the service port 6 to the end space of the compensator 13 where it acts on the spool 18 in addition to the spring 23 so as to oppose the supply pressure which acts on the other end 21 of the spool. When the load starts to move and if the pressure at the service port 6 falls, the supply pressure overcomes these combined pressures, moves the spool 18 to the left causing lands 19, 20 to close ports 14, 15 and restricting the flow so that the predetermined pressure drop is maintained at the port 6. Thus, the rate of movement of the load is set by valve 1 independently of the magnitude of the load. If pressure at the service port 6 rises, the spool 18 moves to the right to maintain the pressure drop. If the load tends to over-run pressure in port 6 drops causing the compensator to close restricting the flow in both service lines so that no cavitation occurs. The pressure from a ball-shuttle valve 24 may be carried through a line 25 to the power unit where it may control an off-loading valve or a swash plate pump. Fig.2 shows how a polarity sensing valve 30 may be used to provide pilot pressures to the shuttle valve 22. Figs.3-10 (not shown), illustrate the construction of a valve block suitable for the circuit described.
