Title: Methods of bonding saturated aliphatic hydrocarbon polymers to other materials and articles so produced
IPC: B32B15/08
Filed: 1957-12-31
Abstract: 849,021. Laminates. WESTERN ELECTRIC CO. Inc. Dec. 31, 1957 [Dec. 31, 1956], No. 40428/57. Drawings to Specification. Class 140. [Also in Groups XV and XXXVI] Saturated aliphatic hydrocarbon polymers, e.g. polythene, polypropylene, poly n-butylene, or polyisobutylene, or mixed or copolymers thereof, are bonded to rubber or synthetic rubbers or to metals, particularly brass, through an -intermediate layer of partially hydrogenated polybutadiene which is heat-sealed to the polythene &c. and bonded to the metal by vulcanizing the intermediate layer or to the rubber or synthetic rubber by vulcanizing the latter. The rubber or synthetic rubber may itself be bonded to metal, using, if the metal is other than brass, bonding compositions such as those containing rubber hydrochloride. The partially hydrogenated polybutadiene may be applied as such or in organic solvent solution and may contain 3-85% preferably 8-30%, of the unsaturations in the unhydrogenated material. The heat-sealing and vulcanizing processes may be carried out simultaneously by -the application of heat and pressure. The rubbers used include soft and hard rubbers and synthetic rubbers such as neoprene, butyl rubber and butadiene-acrylonitrile rubber, but natural, butadiene-styrene, and butadiene rubbers are preferred. In examples : (1) layers of polythene, partially hydrogenated polybutadiene (18% unsaturation), and natural rubber containing vulcanizing agents were superposed and bonded by heat and pressure; (2) the rubber in (1) was replaced by GR-S and the partially hydrogenated polybutadiene applied in solution in toluene, the polythene layer being bonded by heat-sealing either during or after vulcanizing the other two layers; (3) a layer of polythene was bonded by heat and pressure to a brass surface by an intermediate layer, or a number of coatings from toluene solution, of partially hydrogenated polybutadiene containing vulcanizing agents; (4) the polythene in (3) was bonded by heat-sealing after vulcanization of the intermediate layer. As applied to electric conductors an outer sheathing of polythene may be applied by extrusion to an inner coating of partially hydrogenated polybutadiene which may be vulcanized directly to a brass conductor or, in the case of a copper conductor, through an inner layer of neoprene rubber itself bonded to the conductor by a chlorinated rubber composition. Specification 705,338 and U.S.A. Specification 2,147,620 are referred to.

Abstract: 1,205,064. Dehydrated potato agglomerates. J. & J. COLMAN Ltd. 23 Aug., 1968 [23 Aug., 1967], No. 40519/68. Headings A2D and A2E. A readily reconstituted dehydrated potato product of high porosity is prepared by contacting discrete zones of a bed comprising moist potato granules, preferably having a moisture content of from 12-28%, with an aqueous liquid whereby a plurality of discrete moist agglomerates are formed, and isolating and subsequently drying the agglomerates. The moist granules may be prepared by mixing dehydrated potato granules with water or with cooked potatoes. The moist granules are fed on to a conveyer belt or spread on a tray to form a bed, e.g. of 3/16 inch or ¢ inch in depth respectively, on to which water droplets are allowed to fall a distance of ¢ inch to 7 inches. According to the size of the water droplets used, a plurality of agglomerates in the shape of discrete flat discs or spheres is formed. Alternatively, if streams of water are applied to a bed of moist granules on a moving conveyer, rod shaped agglomerates are formed. The moist agglomerates are then separated by a screen from the unagglomerated granules and dried, e.g. by warm air at 150 to 250F., and the unagglomerated granules recycled. Preservatives, surfactants, flavouring, colouring and/or nutritional additives may be incorporated in the agglomerates, e.g. by addition to the water used for moistening the granules or to the water droplets. A suitable continuous apparatus is illustrated diagrammatically.

Title: Herbicidal compositions
Inventor: MIDDLETON MICHAEL ROBERT
IPC: C07D213/22
Filed: 1963-10-15
Abstract: A solid herbicidal composition is made by mixing a hydrate-forming salt with an aqueous solution of a bipyridylium herbicide in proportions such that the hydrate-forming salt combines with sufficient of the water present to give a solid composition.  The hydrate-forming salt may be water-soluble (e.g. calcium citrate, calcium nitrate, potassium alum, potassium dihydrogen phosphate, magnesium nitrate, magnesium sulphate, sodium acetate, sodium orthophosphate, sodium pyrophosphate or sodium sulphate) or water-insoluble (e.g. calcium sulphate). Where a water-soluble hydrate-forming salt is employed, the resultant herbicidal composition may be dissolved in water and applied to weeds in the form of a spray.  For this purpose, the herbicidal composition may contain a cationic or non-ionic surface active agent and a corrosion inhibitor (e.g. sodium benzoate, metaborate, molybdate, nitrite or dihydrogen orthophosphate or dipotassium hydrogen orthophosphate). Where a water-insoluble hydrate-forming salt is employed, the resultant herbicidal composition may be introduced into canals or rivers in order to destroy aquatic weeds.  For this purpose, the release of the bipyridylium herbicide may be retarded by including in the composition a water-insoluble resin (e.g. alkyd resin, urea/formaldehyde resin, phenol/formaldehyde resin, vinyl chloride polymers or copolymers, polyacrylates, polymethacrylates, polystyrene or epoxy resin) or bitumen.  In the examples, the bipyridylium herbicides are selected from 1,1\sv-ethylene-2,2\sv-bipyridylium dichloride or dibromide, 1,1\sv-dimethyl-4,4\sv-bipyridylium dichloride, 1,1\sv-bis-beta-hydroxyethyl-4,4\sv-bipyridylium dichloride, 1,1\sv-bis (dimethylcarbamoylmethyl)-4,4\sv-bipyridylium dichloride, 1,1\sv-bis-carboxymethyl-4,4\sv-bipyridylium dichloride 1,1\sv-bis (diethylcarbamoylmethyl)-4,4\sv-bipyridylium dichloride and 1,1\sv-bis(dimethylmorpholinocarbonylmethyl) - 4,4\sv - bipyridylium di - chloride.

Abstract: 1401118 Character decoders INTERNATIONAL BUSINESS MACHINES CORP 10 Sept 1973 [10 Nov 1972] 42403/73 Heading G4A Variable length, self defining (as to length) characters, e.g. in Huffman code are decoded by scanning a stored sequence of bits representing the sink or inner vertex state in a left list scan of a binary tree representing the character set, in order to detect a sink state which corresponds to an input character. Fig. 1A illustrates a binary tree in which the sink vertices C, E, F, H, J, K correspond to the character set, and Fig. 1B shows the bit sequence T representing the left list scan of the tree for the vertices A-K. Fig. 2 shows a coding algorithm. Initially i, j and C counters, which may be implemented by software, are all set to zero, and the first input character bit PVB is examined for a 0 or 1 value to determine whether the left or right hand path through the tree is to be taken. For the right-hand path, C and j are incremented in successive iterations when inner vertices are encountered, T(j) = 1, and C is decremented and the sink vertex counter i is incremented for each sink vertex encountered, T(j) = 0 until C returns to zero, this operation effectively skipping the left half of the tree. With C at zero the next PVB bit is examined, and if 1, a similar operation takes place to skip a left-hand sub-tree. With a PVB=0, the j counter is incremented and the next PVB is examined, until finally, with C = 0 and T(j) = 0 the sink vertex has been found which corresponds to the input character, and the value of i is output to a decoder, e.g. a matrix. The T sequence may be varied to accommodate changes in code assignments to characters, e.g. to improve transmission efficiency. The j count may be used as output from the decoding process to identify the inner vertices A, B, D, G, I as the decoding process proceeds and operate a relay decoding tree, Fig. 6A (not shown) having outputs corresponding to the sink vertices C, E, F, H, J, K.

Title: Improvements in or relating to coated phosphoric acid anhydride
Inventor: KLEIN GEORGE IRWIN
IPC: C01B25/12
Filed: 1961-11-29
Abstract: <PICT:0957845/C1/1> Particles of phosphoric acid anhydride having individual, substantially uniform, coatings of a slowly water-soluble complex ammonia-phosphoric acid anhydride reaction product are produced by reacting anhydrous gaseous ammonia with a mildly agitated bed of phosphoric acid anhydride particles while the bed is isolated from atmospheric moisture and maintained at a temperature above - 33 DEG  C. but below the sublimation temperature of phosphoric acid anhydride. The phosphoric acid anhydride to be coated may be in the form of finely divided particles or it may be in the form of substantially opaque agglomerated spheroids as produced by the method of Specification 951,383.  In the preferred embodiment either a batch or continuous method may be used, and the apparatus is the same as that used in Specification 957,844.  In a continuous process solid uncoated phosphoric acid anhydride (P2O5) particles are fed continuously through line 6 (see Fig. 1) to a pre-established bed 7 of coated P2O5, the bed being maintained in the expanded state by a recirculating fluidization gas containing NH3.  A make-up stream of NH3 is injected into the recirculating gases either through line 4 or 24.  During the reaction the bed is cooled by vertical cooling plates 8 which are located above the horizontal gas distributing grid 12 and the fluidizing gas supplied to the windbox 13 ascends through grid 12 and the bed 7. The gases leaving the bed 7 pass through pipe 15 and any large particles in the gases are separated in a cyclone and returned to the bed 7 via pipe 16.  The gases pass on via 17 to the wet scrubber where particles too small to be separated by the cyclone are removed by a liquid e.g. polyphosphoric acid and the gases then flow via pipe 23 and the blower back to wind-box 13. The coated P2O5 particles are continuously withdrawn through pipe 33 at a rate substantially equal to the feed rate. Static superatmospheric pressure is preferably used throughout the entire apparatus.  In a batch method the P2O5 feed is prepared by oxidation of a stream of elemental phosphorus entering the combustion chamber through line 1 with air entering through line 2 and the resulting gaseous P2O5 is passed through pipe 3 into bed 7 where it condenses to an agglomerated form.  The combustion chamber is then turned off, the bed is fluidized and ammonia is passed in as in the continuous method.
