Title: Improvements in or relating to playing cards
IPC: A63F1/02
Filed: 1938-09-15
Abstract: 506,137. Playing - cards. WADMAN, A. J. R. Sept. 15, 1938, No. 27013. [Class 132 (ii)] A pack of cards has each card marked with one or more letters and a number e.g. GR, and 5 as shown in Fig. 2 and comprises 56 cards. One or more packs differently marked may be used in a game, the players being dealt say 25 cards each. The cards are played from a facedown position and a player may call a word which is formed by the letters of the cards when exposed and if correct he obtains the pile in which these cards occur. A caller may be challenged before he has taken a pile and if wrong the challenger wins the pile and if right the challenger loses his pile to the pool. The winner is he who obtains all the cards ultimately or if the game stops before this he who has the highest numerical total.

Abstract: 879,690. Labelling machines. MEYER MANUFACTURING CO., GEO. J Aug. 4, 1960 [Aug. 27, 1959], No. 27046/60. Class 73. Relates to labelling machine for applying shoulder labels to bottles while the bottles are moved uninterruptedly by a conveyer along a path, wherein a. suction pad receives a label from a picket at a transfer position and is then moved to apply the label, the pad when in the label-affixing position moving with the bottle along, the path for a predetermined distance, then moving away from the bottle and returning to the transfer position. According to the invention spring-loaded carrier Z2 Figs. 1, 5 for the shoulder label pad P<SP>1</SP> is pivotally mounted at 37 at the end of a rock arm M fixed to a. shaft K which is arranged to rock and to move endwise parallel to the conveyer path, and a fixed horizontal bar 111 also extends parallel. to the conveyer path, the arrangement being such that on movement of the rock arm from the transfer position (shown in broken lines in Fig. 1) to the label-affixing position (shown in full lines) a roller 103 freely rotatable in the carrier Z2 engages the bar 111 and pivots the carrier against the action of its spring. to bring the pad P<SP>1</SP> into contact with the bottle shoulder D-and to maintain it there. during movement of the pad and bottle along; the conveyer path. During this movement also, a cam face 104 on the carrier Z2 engages a. roller 119 on a fixed vertical shaft so that the label is pressed yet more firmly into contact with, the bottle; As shown the rock arm M is, also provided with a body label applying pad: <SP>p2</SP> as described in Specification 864,625 and the machine generally- and in particular the arrangement of pickers are described in Specification 805,074.

Abstract: 841,247. Separation of plutonium. RITTER, D. M. Oct. 20, 1945 [Oct. 12, 1944], No. 27648/45. Drawings to Specification. Class 39(4). Plutonium is recovered from an aqueous solution containing also uranium and fission products by subjecting the solution with the plutonium in an oxidized state to a fluoride precipitation to remove contaminants, complexing residual fluoride ions in the solution, and then subjecting the solution to a bismuth phosphate precipitation to carry down the plutonium. In the process particularly described, a nitric acid solution of neutronirradiated uranium is reduced with formic acid or ferrous or uranous ions, treated with sulphuric acid, and then bismuth nitrate and phosphoric acid are added to form a precipitate of bismuth phosphate which carries down the plutonium; the precipitate is dissolved in nitric acid, oxidized with sodium bismuthate and a dichromate, and a precipitate of bismuth phosphate again formed, impurities being carried down leaving plutonium in solution; the solution is treated with lanthanium nitrate and hydrogen fluoride in the presence of a dichromate to form a precipitate of lanthanum fluoride which carries down impurities e.g. fission products ; boric acid, sodium metaborate, or borax is added to complex the residual fluoride, the solution is reduced with ferrous ion, uranous ion, oxalic acid, or hydrogen peroxide, and a precipitate of bismuth phosphate once more formed to carry down the plutonium; the precipitate may be treated with gaseous fluorine to form volatile plutonium fluoride which is condensed, any boron being first removed as BF3. U.S.A. Specification 2,785,951 is referred to.

Filed: 1925-11-04
Abstract: 260,106. Ashley, W. E., Vickers, C. J., and Stott, H. Nov. 4, 1925. Rotary apparatus.-An intermittently-operated revolving sewage distributor comprises an annular tank e revolving about a central supply column a, its lower end dipping into a mercury seal f. Siphons feed the distributor arms j, and are provided with means to start and break siphonic action. The portion d<2>, Fig. 1, of the sleeve d projecting beyond the flange d<1> extends into the tank e, dividing it into two chambers the outer of which forms a common short leg for a series of siphons h formed by vertical passages restricted at h<1> and preferably rectangular in section extending down the outside of the tank e and communicating through traps i with the distributor arms j. The tank e receives its supply through ports k in the column a. The diameter of the column is such as to form a restricted passage at m just above the openings k. Above this the column a is narrowed, and air ports n are formed above the flange d'. When the supply in the dosing-tank fails, the level falls in the supply column faster than in the inner chamber of the tank e. When it falls below the lower end of the sleeve d, air will be sucked into the outer chamber to break siphonic action. As shown in Fig. 3, the tank e is open at the top and separate short legs h<2> are provided for the siphons, the siphonic action being broken by U-shaped air admission tubes o. In Fig. 4, the short legs h<2> are formed in the central column, the upper part of the tank e carrying the long legs h being closed at e3 and resting on bearings c<1>. The upper parts of the long legs h are enlarged at h3 and inclined to communicate with circumferential ports p. Each short leg is provided with an air admission tube o to break siphonic action. The distributor arms are provided with steam line nozzles.

[Class 98 (i)] In a shutter with a rotating obturating blade having an aperture through which an exposure is made and carrying a contact cam, the distance from the axis of rotation of the blade to the contact cam is less than the distance from the axis of rotation to the centre of the aperture. As shown, a disc 3 is rotatable between limits on a spindle 4 on a plate 1 so that an aperture 5 in the disc passes over an aperture 2 in the plate to make an exposure. A spring 12 connects disc and lever 6, so that when the lever is rocked disc 3 rotates and an exposure is made. Lever 6 is returned by a spring 18 and returns the disc, and extension 17 covering aperture 2 to prevent a second exposure. A finger 15 on an insulating foot 14 extends between disc 3 and plate 1, and a contact cam 16 is carried by the disc 3 closer to spindle 4 than is the aperture 5. Cam 16 and finger 15 make contact to close a flash-lamp circuit at such a time before the shutter opens that the radiation from the lamp reaches maximum intensity approximately at the middle of the period during which the shutter is open. Alternatively, two fixed contacts may be closed by the cam 16.
