Title: Improvements in and relating to machines for breaking coke and the like
IPC: B02C4/30
Filed: 1932-02-19
Abstract: 394,430. Roller mills. GREEN, R. W., 16, Lower Oldfield Park, Bath, and ALDRIDGE & RANKEN, Ltd., 39, Victoria Street, London. Feb. 19, 1932, No. 5035. [Class 59.] In a mill for breaking coke, the drums or barrels of the spiked rolls are formed with dovetail or undercut longitudinal grooves, and the spiked rings or ring segments mounted on the drums are formed with corresponding lugs or tongues. As shown in Fig. 2, segmental or continuous rings d carry spikes f and are secured to the drum a by means of dovetail lugs e engaged in longitudinal recesses c. The adjoining edges of the segments are ground and the abutting ends of the segments, which form a complete ring, together form a dovetail lug which is housed in one of the recesses c. The several rings are held together by bolts g which pass through the lugs and through a flange on the drum. In order to facilitate the removal of the drum from the driving shaft, the flange h, Fig. 4, on the drum is adapted to be centralized with the flange h<1> on the driving shaft through the medium of a semicircular flanged lip j.

Title: Improvements in or relating to the production of paper
IPC: D21C9/00
Filed: 1929-02-15
Abstract: 326,956. Jackson, L. Mellersh-, (Mathieson Alkali Works). Feb. 15, 1929. Pulp, preparation of; pulp, catching and recovering.-Pulp stock and the raw water used for its dilution are treated with chlorine to destroy slime forming organisms and so overcome the slime problem and reduce the losses occurring in the white water. The chlorine may be used in the manufacture of the pulp and sufficient left in the pulp to prevent the formation of mould during storage, or the treatment may be effected before or during beating, or the chlorine may be added to the stock while in a high state of dilution in the mixing box supplying the paper machine. The chlorine treatment may be effected with gaseous chlorine or by chlorine water, or by a solution of hypochlorous acid or of a hypochlorite, and the quantity should be sufficient to leave a residual chlorine content in the stock of ¢ to 1 part per million. Before flowing on to the paper machine, coagulating material is also added to effect the coagulation of a considerable amount of short fibres and colloidal and finely divided material which is held in the paper produced instead of running away with the white water. Suitable coagulating materials are alum, alum with sodium aluminate, alum with caustic soda, ferric chloride &c. and they may be used in the proportion of 1-2 lbs. per 1000 gallons of water treated. The chlorination and coagulation treatment of the stock results in increased hydration of the cellulose so that the duration of the beating operation (which is also a hydration operation) may be reduced. As the absorption property of the pulp is lowered by increased hydration, the beating of felt and blotter stocks treated according to the present process should be reduced. The process gives a highly hydrated but free flowing pulp from which water rapidly separates, giving increased speed of operation and making possible the use of finer wire screens. The white water will be free or practically free of coagulatable material and may be run to waste or employed in the mill to replace the freshly chlorinated water. The time lost in cleaning the machine is reduced. Specification 25385/12 is referred to.

Title: Treatment of zircon ores
Inventor: RUSSELL JAMES ROBINSON
IPC: C22B34/14
Filed: 1960-02-13
Abstract: Alkali metal zirconates are obtained by heating zircon to at least 300 DEG C., and then adding an aqueous alkali metal hydroxide solution at a temperature not higher than its boiling point.  The hydroxide solution preferably contains 10-75% hydroxide by weight, and is preferably employed in an amount not so great as to produce a liquid mixture with the zircon.  The zircon, which is preferably finely divided, may pass through a rotary kiln, and the solution sprayed in along the kiln.  A dam may be provided in the kiln so that a bed of zircon at least one inch deep may be formed. The preferred hydroxide is sodium hydroxide.  Potassium and lithium hydroxides are also specifically referred to.

Title: Machine for forming and inserting wadding in containers
Inventor: LAKSO EINO ELLIS

Filed: 1964-02-07
Abstract: 1,030,353. Making wadding for containers. LAKSO CO. Inc. Feb. 7, 1964, No. 5265/64. Heading B8C. Wadding for containers is formed by forcing a sheet 28 (Fig. 1) of material into a tube 26 to form a tubular wad, and then ejecting the wad into the container. In one configuration (Fig. 1) four forming tubes 26 are fixed on a turret 20 which is rotated intermittently. A mandrel 24 pushes the sheet 28 into a tube 26 via a guide 86, the tubular wad so formed being later pushed from the tube 26 into the container C by a plunger 46. The sheets 28 are cut from a web 32 fed by rollers 34 whose speed can be varied to vary the lengths of the sheets. The container C may be placed on the support 22 by hand, or by a conveyer mechanism. In a manually operated form of the invention (Fig. 7, not shown), a mandrel 165 is moved upwards by a foot mechanism 168 to force a sheet of material, supported by resilient tines 172 into a tube 154. After the retraction of the mandrel a container is placed on the support 150 and the wad is thrust into the container by the plunger 158, which is operated by the lever 162.

Title: Improvements relating to the production of aroxy silicones
IPC: C08G77/14
Filed: 1941-04-24
Abstract: 548,912. Resinous organo-silicon compounds. BRITISH THOMSON-HOUSTON CO., Ltd. April 24, 1941, No. 5295. Convention date, April 27, 1940. [Class 2 (iii)] Resinous aroxy silicones are obtained by hydrolysing an aroxy silicon dihalide of the formula (A-O-A<SP>1</SP>) 2  Si 2 , where A is a non- halogenated aryl radical, A<SP>1</SP> is an alkyl or non- halogenated aryl radical and X is a halogen atom, and dehydrating the hydrolysed product. Silicones containing less than two aroxy radicals per silicon atom may be similarly obtained from a mixture of different aroxy silican halides which may be separately hydrolysed before dehydration. Initial products are viscous liquids, soluble in organic solvents, which are further dehydrated by heating to form solid resinous masses. These products may be applied as coating compositions or compounded with other materials, as described in Specification 544,143. Solid products having less than two aroxy radicals for silicon atom may also be obtained by admixing and grinding individual silicones. In an example a mixture of di- and mono-phenoxyphenyl silicon chlorides, obtained by reacting phenoxyphenyl magnesium bromide with silicon tetrachloride, in ether solution, was hydrolysed by pouring the cold solution on to cracked ice and, after washing with water, the product was partly condensed by distilling off ether and heating to 110‹C. for 4 hours to yield the viscous liquid product; by further heating to 150-225‹C. for 1 hour, this was converted to a brown, hard resin.

Abstract: 1488935 Learning machine DENDRONIC DECISIONS Ltd 11 Feb 1975 [28 Feb 1974] 5768/75 Heading G4R A learning network has a plurality of elements which may be arranged in a tree network. Three elements are shown in Fig. 1 but the tree can be larger. The elements used are shown in Fig. 2. The variable connections unit 128 under the control of unit 127 provides predetermined signals on leads 106, 108, 110, 112. by determining the connections between leads 106, 108, 110, 112 and leads 114, 116, 118, 120. The network has four modes, training, reading out, setting and use. In training a series of ntuples is placed on leads 114-120 and the desired output value on lead 126. Each unit (Fig. 2) when operating as a two input 202, 204 one output 200 combinational circuit has a logical operation determined by function value units 215, 218 and can realise any of four functions depending on the values of leads 213, 216. These are AND, OR, LEFT gate or RIGHT gate. The heuristic responsibility units 219, 220 are influential only during training and carry zeros during the other periods and are used to produce restrictions of the specified function to certain subsets of n-tuples. The function valve unit contains a counter which produces a "1" output if the value stored is above a predetermined amount or a "0" output otherwise. The unit determines by a simple statistical counting technique whether there are more ONE or ZERO desired outputs indicated when the given element is heuristically responsible and when a certain input pair occurs on leads 202, 204. If there are more ONES the counter remains in the upper half of its count and produces a "1" output. A circuit of the counter is illustrated (Fig. 4, not shown).
