Patent GB-589024-A (GB)
Title: Improvements in and relating to the polymerization of mono- and di-saccharides
IPC: C08B37/00
Filed: 1942-11-03
Abstract: Mono- and di-saccharides are polymerized by incorporating a catalyst and heating in a molten state under substantially anhydrous conditions in contact with superheated steam as a co-catalyst.  In one example, a -anhydro dextrose containing .001-.1 per cent by weight of hydrochloric acid gas is heated for 6 hours (1 hour to melt the sugar and 5 hours for polymerization) at 150 DEG  C. on trays in an oven, through which superheated steam at about 150 DEG  C. is passed continuously.  Other strong mineral acids, e.g. sulphuric or phosphoric, or acid salts, e.g. sodium bisulphate or zinc chloride, may be used instead of hydrochloric acid.  Alternatively, 1 per cent of a substantially neutral salt (pH 5-7), soluble in molten dextrose, such as sodium, potassium or magnesium sulphate, sodium, potassium or barium perchlorate, sodium or barium chloride, sodium bromide or potassium iodide, .2 per cent acetochloro glucose or 1 per cent boric anhydride or ortho-, tetra-, or, preferably meta-boric acid may be used as catalyst.  In the case of substantially neutral salts, the amount and degree of polymerization increase with the time of treatment.  Barium perchlorate and hydrochloric acid together are more effective than either alone.  In other examples, xylose, laevulose and maltose are treated with 1 per cent meta-boric acid for 5 hours at 150 DEG  C., maltose with .005 per cent hydrochloric acid for 5 hours at 135-140 DEG  C. and sucrose with 1 per cent sodium chloride or barium perchlorate for 5 hours at 150 DEG  C.  Where metaboric acid is used, the sugar is melted by immersing the container in an oil bath at 100 DEG  C. and then raising the temperature to 155 DEG  C. in the case of dextrose, 160 DEG  C. for xylose and 170 DEG  C. for sucrose.  The Specification as open to inspection under Sect. 91 comprises also the heat treatment of any sugar with a catalyst under substantially anhydrous conditions.  This subject - matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for emptying containers
IPC: B65G65/23
Filed: 1953-06-09
Abstract: 741,335. Endless conveyers; tipping milk churns. UNITED DAIRIES (WHOLESALE), Ltd., and KING, J. E. Sept. 8, 1954 [June 9, 1953], No. 15898/53. Classes 78 (1) and 78 (4). Apparatus for tipping milk churns to empty their contents into a receiver comprising an endless elevator terminating above the receiver, means for delivering the containers successively on to the elevator and means at the upper end of the elevator for causing each container to tilt about a horizontal axis is characterized in that the elevator comprises two spaced endless chains or bands which have secured between them a number of crossbars so spaced that when a container rests on one bar another bar above it engages a side of the container so that the container is held and positioned solely by the bars when being elevated. In the embodiment shown, the churns are fed one at a time by an endless belt conveyer 41 to an elevator comprising a pair of endless chains 32 extending around sprockets 12, 29 and 13, 28 respectively, and connected by bars 34. The shaft 11 carrying the sprockets 12, 13 is driven through chain-and-sprocket gearing 18, 19 by a motor 20, whilst the conveyer 41 is similarly driven from this motor. Two pegs 46 mounted on a yoke 47 pivoted at 48 to an arm 49 fixed to a spindle 50, are brought into and out of the path of the containers in timed relationship to the movement of the elevator whereby when a container reaches the elevator it is first engaged by one bar 34 and then its bottom engaged by another, the transfer being assisted by a roller 45 driven through chain gearing from the shaft 40 of the conveyer 41. The pegs are operated by a cam 54 on a shaft 23 driven by chain gearing from the shaft 11, engaging an arm 53 connected by a rod 52 to a lever 51 secured to the spindle 50. Where an even number of bars 34 are provided, the lever 51 is curved to form a finger which is struck by a short extension at one end of every alternate cross-bar, the mechanism 52, 53, 54 being unnecessary. When a churn reaches the top of the elevator it is engaged by the curved edge 15 of a semicylindrical pusher 14 fixed to the shaft 11 so as to be pushed off its lower supporting bar 32. It then slides off its leading bar on to a bar 55 extending along a " drain conveyer 27 with its front end engaging a rail 57, and is eventually moved longitudinally of a milkreceiving tank disposed to the left of Fig. 1, by arms 56 on the drain conveyer. This latter is driven through chain gearing from a shaft 25 driven through bevel gearing from the camshaft 23.

Title: Improvements in undercarriages for aeroplanes
IPC: B64C25/62
Filed: 1930-05-23
Abstract: 355,348. Aeroplane undercarriages. GRAY, W. E., 8A, Bank Parade, Edgware, Middlesex. May 23, 1930, No. 15975. [Class 4.] In an aircraft undercarriage of the type wherein two sets of wheels are provided one set in front of, and one under or slightly in rear of, the centre of gravity of the aircraft, the front set of wheels is arranged to have a considerably greater travel of springing than the rear set. A spring arrangement is used for the front wheels having a load-deflection curve of the type shown in Fig. 1, wherein AB represents deflection, BC load, and CD rebound deflection. In one such arrangement, Fig. 2, a long coiled spring K is so arranged as to be initially compressed by a shorter rebound spring J placed below the moving element H fixed to the weight carrying member which spring acts on the spring K over the first part of the travel corresponding to the initial steep part of the curve shown. After further travel a short coiled spring L is arranged to come into action causing the second steep slope of the curve. All three springs are approximately of the same strength. When the aircraft is at rest on the ground the front wheel deflection corresponds to the earlier part of the flatter portion of the curve. According to modifications a single spring may be used having a portion of lesser diameter or of larger gauge material or of both. When tyres of very large diameter are employed the springing to give large travel has a load-deflection curve similar to the centre portion only of the curve in Fig. 1. Specifications 274,167, 289,109, 338,514, and 338,515, [all in Class 4, Aeronautics], are referred to.

A pleating-machine comprises pleating-bars movable towards and away from a material supporting member and towards and away from each other to grip and release the material, steam and air passing through the bars to set the pleats. As shown, Fig. 1, pleating-bars f are supported by a frame c, c<1> telescopically mounted in sleeves b<1> of brackets b. Springs g on sleeves e carried by the frame and welded to the bars # urge the bars into engagement with each other. Cam members (not shown), associated with extensions e<1> carried by the sleeves e, are operable by means of a pedal o and links m, j<1> to separate the bars f against the action of the springs g. The material-supporting member comprises a tube q, which may be perforated at s and connected to a source of suction or vacuum, and a blade q<1>. The bars f are normally retracted away from the blade q<1> by springs t extending between the lower bar f and the brackets b. Movement of the bars towards the blade is effected by a pedal u connected by a link v to the frame member c<1>. Adjustable stops x limit forward and rearward movement of the bars. Pipes y, y<2> and z, z<2> supply steam and vacuum, respectively, to the interior of the bars. Steam condensate is withdrawn through tubes 2. In operation, material is placed on the tube q with the edge of the blade q<1> locating the pleat. The pedals o or u are then pressed to separate the bars and move them towards and on to the blade q<1>, Fig. 4. The pedal o is released, then the pedal u, the bars with the material gripped between them being retracted by the action of the springs t until the lower abutment stop x is contacted. During the retraction, first steam and then air is supplied to the interior of the bars. The pedal o is pressed again to release the pleat. The distance between successive pleats is determined by the location of the stops x which are independently adjustable to allow for tapered pleating. Alternatively the supporting member q, q<1> may be adjustable toward and away from the bars f and pivotally about its support q<2>.

Abstract: <PICT:0437681/III/1> In a plant for the production of ammonium sulphate and bisulphate by the absorption of ammonia, in a sulphuric acid saturator 5, distilled off from concentrated ammoniacal liquor, containing from 12 to 20 per cent of ammonia, in a still 6, the liquor is passed upwardly through an unobstructed single tube jacketed preheater 1 heated indirectly by hot waste gases from the saturator flowing downwardly through the jacket, before its admission to the still through an offtake 7 of continuously decreasing cross-section. The upper part of the still is empty so as to constitute a vaporizing chamber for the instantaneous dissociation of the ammonium compounds in the liquor prior to its passage through bubbling trays in the lower part of the still.  The offtake may discharge the liquor on to a distributer in the still such as a saucer of cast iron.  The purified liquor from the still may be used for steam raising for heating the still and also for agitating the sulphate crystals collected in a well 20 within the saturator to encourage their growth by suspension in the mother liquor.  For the latter purpose the steam is fed into the saturator through a pipe 19. An automatic regulator, such as a hydraulic regulator of the leak-port type, may be used to control the feed of liquor to the preheater in accordance with the steam feed to the still. Thermostatic control operated by the stillhead temperature may also be adopted.
