Abstract: 1,202,192. Electro-slag refining. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 12 Sept., 1967 [13 Sept., 1966], No. 40789/66. Heading B3F. In electro-slag refining, relative motion is brought about between the mould and electrode in a direction transverse to the vertical axis of the mould without rotation of the mould about its vertical axis, although the vertical axis of either the mould or electrode may move in a closed-figure path. The mould may be placed on a platform 1 supported on bearings 2 on a trolley 3, the platform 1 being moved in a circular path by cranked drive 4 whilst the platform does not rotate about its own axis. Alternatively the platform 1 may be moved by a pair of hydraulic or pneumatic jacks (5) (Fig. 3, not shown) acting at right-angles to each other. In a further embodiment the electrode is moved relative to the mould by rotating an electrode holder (6) (Fig. 4, not shown) on which an electrode (7) is eccentrically mounted, the movement being arcuately reciprocated or a continuous circular movement (Fig. 5, not shown), in which the axial orientation of the electrode remains constant.

Title: Improvements in or relating to processes for polymerizing conjugated diolefins and to the polymerised diolefins produced thereby
IPC: H01M6/06
Filed: 1958-12-29
Abstract: Polymers of conjugated diolefines having a 1,2-configuration of at least 80% and a molecular weight of 2,000-500,000 and prepared by polymerization in the presence of an organolithium compound and an ether solvent are used for coating metals or wood. The polymer is dissolved in a suitable solvent or used in solution as prepared and applied by dipping, painting or rolling and cured at 95-260 DEG  C. for 10-30 minutes.  A cobalt drier may be added in amounts of 0.01-2% by weight.  The coatings on metal have good resistance to hot solder and are particularly useful in lining cans for food or drinks.  The polymer may also be epoxidized by reaction with an organic peracid and such epoxidized products form hard, insoluble, infusible coatings on curing with an amine curing agent in a solvent, with heating if desired.ALSO:Conjugated diolefines are polymerized by bringing into contact with an organic lithium compound in an ether solvent and an inert atmosphere; the products have a 1,2-configuration of at least 80% and are thick liquids or solids having molecular weights (light scattering technique) of 2,000-500,000.  Diolefines specified are butadiene, isoprene, dimethylbutadiene, piperylene, and methyl pentadiene which may be copolymerized with up to 30% by weight based on the total monomer of a second monomer such as styrene, alpha-methylstyrene, divinyl benzene, vinylpyridine or 2-methyl-5-vinylpyridine.  The catalyst is preferably a hydrocarbon lithium or polylithium, e.g. ethyl-, butyl-, phenyl-, n-dodecyl-, octadecyl-, allyl-, phenyl-, cyclohexyl- or octyl-lithium, methylene-, ethylene-, pentamethylene-, decamethylene-, 1,4-benzene- or naphthalene-dilithium or 1,2,6-trilithium hexane used in amounts of 0.001-0.1 mol. per mol. of monomer.  The ether solvent may be cyclic or acyclic, e.g. tetrahydrofuran, dioxane, diethyl ether or diamyl ether, and is used in amounts of 0.3-1.7 mol. per mol. of diolefine.  Other solvents up to 25% of the total solvent may be added, e.g. benzene or toluene.  Inert gases suitable for maintaining the inert atmosphere are nitrogen and methane.  Temperatures of -40 DEG  to 100 DEG C. are used and the pressure may be autogenous or higher or lower.  Butadiene is preferably bubbled into the solvent-catalyst mixture over a period of time, e.g. 30 minutes to 4 hours.  The catalyst is destroyed by adding water or alcohol in excess or in just sufficient quantity.  The polymers may be used to form coatings which may be cured at 95-260 DEG C. for 10-30 minutes. Cobalt driers may be added.  The polymers may also be epoxidized by reaction with a peracid such as performic, peracetic, perbenzoic, or monoperphthalic acid at - 20 DEG  to 100 DEG C.  The epoxidized polymers may be cured with amine curing agents.

Title: Image scanning system
IPC: G06K15/22
Filed: 1966-09-26
Abstract: 1,098,336. Image scanning systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 26, 1966 [Oct. 18, 1965], No. 42812/66. Heading H4F. A cathode-ray tube scanning an image an a film to generate video signals in a photoelectric cell is controlled by a digital computer which supplies two digital numbers defining the x and y components of a desired incremental scanning movement of the cathode-ray spot and a third digital number which defined the number of times the movement is to be repeated so as to produce a progressive scan. During each incremental scanning movement the video signal is sampled six times in succession to determine whether the signal crosses a threshold level indicating the presence of an image portion. The results of the signal samples are stored. At the completion of each movement, providing an image portion has been detected in at least one sample interval, digital signals are passed into the computer store which denote: (1) the individual results of the six sampling operations, (2) whether an image portion has been detected in at least one of the first three samples, (3) whether an image portion has been detected in at least one of the last three samples, (4) whether an image portion has been found in each of the six samples, (5) whether an image portion was detected in the previous incremental scanning movement, and (6) the x and y co-ordinates of the scanning spot at the completion of the incremental scanning movement. An arrangement for carrying out the invention is described (in block diagram form only) with reference to Figs. 1 and 2 (not shown). The invention is said to be for use for providing the input data for computer controlled graphic displays utilizing cathode-ray tubes.

Title: Arithmetical multiplying systems
IPC: G06F7/52
Filed: 1970-09-10
Abstract: 1329272 Decimal multipliers HONEYWELL Inc 10 Sept 1970 [12 Nov 1969] 43393/70 Heading G4A A system for multiplying two multi-digit decimal numbers includes a store which holds at least five different multiples of the multiplicand. In accordance with the sum of the current and immediately previous multiplier digits, one of the stored multiples is selected and passed to an arithmetic unit. In accordance with the sum, the arithmetic unit either adds or subtracts the selected multiple and a partial product obtained from an accumulator, the result being applied to the accumulator as a new partial product for use in the following addition or subtraction. In the system described, Fig. 1, each decimal digit is represented as a 4-bit character. Initially the accumulator register 10 stores the multiplicand and a product register 20 stores the multiplier, both received from the main store via N Register 16. Six multiples (Î 0-x 5) of the multiplicand are formed and are stored in a scratch-pad memory 50. The least significant digit of the multiplier in register 20 selects a corresponding multiple from memory 50 via incrementer 49, gates 52, and address register 56. Should the digit be other than one of the numbers 0-5 the required multiple is derived by forming the tens complement of the selected multiple by forming the nines complement and adding one to the least significant digit of the result. For example, if the least significant multiplier digit is 9 the x 1 multiple of the multiplicand is read out. Because, in this instance, the sum of the previous multiplier digit (0) and the present digit (9) is between 6 and 10 the nines complement of the x 1 multiple is added at 26 to the number (now zero) in register 10. A 1-bit is added to the lowest position, resulting in the tens complement. This result is stored in register 10. The least significant digit of the result is placed in register 20, the content of register 10 shifted one place right, and 9 or 0 as appropriate, forced in to the most significant position in register 10. The next multiplier digit now selects a corresponding multiple from memory 50, dependent on the value of the sum of the present and prior multiplier digits. The multiple, complemented if necessary, is added at 26 to the partial product in register 10 formed during the previous cycle. As in the previous cycle the least significant digit of the result is passed to register 20 and the most significant digit forced to 9 or 0. The process continues until all the multiplier digits have been used, the required product then being present in register 20.

Abstract: 1,089,598. Magnetic separators. D. WESTON. Sept. 30, 1966. No. 43898/66. Addition to 963,746. Heading B2J. In a modification of the apparatus of the parent Specification, a pair of spaced rotatably movable liner rings 5, 6, Fig. 1, are mounted within the non-magnetic wall 1 of the elongated chute in order to prevent wear of the wall by friction caused by movement of the more strongly magnetic particles, the liner rings being disposed adjacent opposite sides 2, 4 of the wall 1. The liner rings are made of low friction, non magnetic material such as P.T.F.E., and have grooved surfaces 7 in contact with the sides 3, 4 to diminish friction. Gaskets 8 and annular rings 10 of magnetic material are inserted in grooves 9 in the liner rings. In operation, the particulate material is attracted to the face of the rotatable liner rings and as the magnetic poles N, S rotate, both the rings and the particulate material rotate. At the discharge section of the chute, Fig. 4, a block 12 is provided against which the particulate material is concentrated before being discharged by means of a paddle wheel 13. The block 12 is spaced from the sides 3, 4 of the wall 1, Fig. 6, to allow movement to the liner rings 5, 6, the space between the block and the liner rings being sealed by fingerlike seals 16 carried by the block and urged against the rings by air fed under pressure to the seals from chamber 18 and channels 17 in the block. In another modification, the poles are those of electromagnets and collection of the concentrate is effected by shutting off or reversing the current supplied to a selected group of the electromagnets at the zone embracing the discharge section of the chute. The winding material for the electromagnetic poles may be made of cryogenic metals, e.g. Cb-Zr or Ob-Su alloys, whose electrical resistivity decreases with decrease in temperature. For temperatures at or below -30‹F refrigerated brine, liquid nitrogen, helium or hydrogen may be used as coolant. The poles of the magnets may have coiled copper cooling tubes separated from the windings and from the ambient environment by insulation, Fig. 7 (not shown).

Abstract: 1,169,629. Cutting-apparatus. J. H. GREEN. 27 Sept., 1967 [6 Oct., 1966], No. 44014/67. Heading B4B. [Also in Division F2] Apparatus for cutting a travelling paper web comprises a blade 98 positioned on a carriage 52 movable transversely between limit positions on a vertically-adjustable track, the carriage having mounted thereon a sprocket wheel 154, Fig. 4, around which passes an endless chain 160 which also passes around a drive wheel 166 and an adjustable idler wheel 168, Fig. 5 (not shown, the wheel 154 being connected by means of a crank-pin 156 and a connecting rod 158 with a tubular member 142 slidable on a rod provided with a stop 150, and the arrangement being such that when the chain 160 is driven forwardly, the wheel 154 is rotated counterclockwise to project the blade 98 to penetrate the web, such projecting continuing until the connecting rod 158 engages the stop 150 after which the carriage is moved forwardly to sever the web. The track comprises two tubular members 42, 44 secured toone another, and the drive wheel 166 is driven by a reversible motor 182. The apparatus enables a web 12, Fig. I, to be severed between drums 16, 26 so that the forward severed end of the web may be wound upon an empty core 24. To this end, the web is severed along line 28 and then torn off to form a starting end 32 which is wound about the core 24. Severing of the web then proceeds from the line 28 along a diagonal line 34 until the web is completely severed. A contact 228, Fig. 3, on the carriage engages a contact 230 secured to the track to energize one-way brake means, Fig. 14 or Fig. 15 (neither shown) engageable with the sprocket wheel 154 to prevent displacement of the blade from its retracted position until the carriage has moved a predetermined distance from its starting position. The blade 98 is rotatably mounted on an axis inclined to the axis of the member 142 so that the blade is angularly displaced by the web in response to movement of the carriage. Movement of the carriage is initially resisted when the carriage is in either of its limit positions by means of a pair of friction brake assemblies 200, Fig. 3. Stop blocks 108, 110, Fig. 4, on the carriage are engaged by shock absorbers 112 at the opposite ends of the track. The carriage is provided with extensions 244 engageable with limit switches 246, 248, 250 and 252 to control operation of the apparatus. During the severing action, a water spray is applied to the web. The apparatus is controlled either manually or by an automatic cycle controlled by an electric circuit illustrated in Fig. 17 (not shown).
