Abstract: 1,213,056. Photographic antifoggants. EASTMAN KODAK CO. June 20, 1968 [June 20, 1967], No.29394/68. Heading G2C. [Also in Division C2] Photographic anti-foggants comprise N, N- disubstituted aminomethylthiocarboxylic acids having the formula:  or  or an ester or salt thereof, wherein A is a tertiary amino radical in which the nitrogen may be part of a heterocyclic ring, Z is an aliphatic carbon chain which may be substituted, e.g. by alkyl, aryl, carboxy or carboxyalkyl groups, and X is a ditertiary amino radical, preferably a piperazine ring. The anti-foggants may be incorporated in the emulsion, either before or after an after-ripening stage, or in a layer contiguous thereto, or may be added to the developer.

Title: Improvements relating to the continuous casting of molten metal
IPC: B22D11/14
Filed: 1953-10-23
Abstract: 744,213. Continuous-casting machines. OHIO CRANKSHAFT CO. Oct. 23, 1953 [Oct. 27, 1952], No. 29418/53. Class 83 (1). [Also in Group XI] A continuous-casting apparatus in. cludes an externallycooled rectangular mould A open at its ends, pinch rolls B which continuously withdraw a solidified metal bar therefrom, and a tundish C supplying molten metal to the mould from spouts 22. The tundish C has a refractory lining 21 of high heat- and electrical-conductivity and layers 26, 27 of high heat-conductivity, and an outer steel wall 25. An inductor coil 30 is embedded in the layers 26, 27 and further inductor coils 34 surround the spouts. The coils are of copper tubing and are fed from a high-voltage source via adjustable reactances. The temperature of the metal in the tundish is controlled by the heating effect of the coils or the cooling effect of fluid-passing through the coils. The spouts and the lining 21 are provided with separate thermocouples which automatically regulate the power supplied to the coils. In order to produce a more even cooling of metal in the mould the temperature of the metal emerging from the outermost spouts is arranged to be higher than that of the metal emitted from the inner ones. Valves may control the flow from the spouts.'

Title: Automatic character-recognition circuit
IPC: G06V30/10
Filed: 1961-08-16
Abstract: 934,558. Automatic character reading. STANDARD TELEPHONES & CABLES Ltd. Aug. 16, 1961 [Aug. 17, 1960], No. 29600/61. Class 106 (1). A series of analogue voltages corresponding to the grey value of each of the scanned points of a character are fed to a quantizer U which converts the analogue voltages into two series of binary signals a, b connected respectively to the input stages of shift registers 3, 4 which are operated synchronously with the scanning of the character by means of a clock pulse generator T. During displacement of signals a, b through shift registers 3 and 4, each point of the character is transferred into a subset of stages 5 representing a sub-area of the character. Connected to stages 5 is a logic circuit 6, which combines the binary signals a, b by an empirical rule, and a series of single binary signals corresponding to each point is stored in a shift register 7, operated synchronously with registers 3, 4 and to which is connected a circuit 8 for final recognition of the character. Each binary output signal from circuit 6 is determined both by the signals a, b for the particular point and by those for certain neighbouring points. By connecting the last stages of registers 3, 4 via decoupled lines 300, 301 to the first stages of the shift registers, both the original and the simplified black-white characters are stored simultaneously and a comparison check may then be carried out.

Title: Improvements in the method of and means for manufacturing pipes of fibro cement and like material
IPC: B28B21/48
Filed: 1937-11-02
Abstract: 506,913. Moulding pipes by centrifugal machines. PORTER, W. A. Nov. 2, 1937, No. 29955. [Class 87 (ii)] Pipes are formed from preformed cementitioussheet material by winding the preformed sheet in a plastic state on a mandrel within a mould, bringing the edge of the sheet into contact with the inner surface of the mould, and transferring the sheet from the mandrel to the mould which is rotated at a speed sufficient to cause adherence of the sheet. The mould 2 is formed of three segments hinged and locked together by bolts 10, and it may either have an inner pallet for supporting the formed pipe or a two-piece lining 12, Fig. 7, supported by blocks 13 and ribs 13<2>. The mould is provided with annular tracks 11 which seat on rollers 3 and are held thereon by rollers 62<2> carried by inclined rods 62 mounted on columns 65. The rods 62 and columns 65 are both adjustable longitudinally by screws and hand wheels 61, 66 respectively. The mandrel 14 is hollow and is supported in the mould by open topped bearings 15, 16 and end bearings 19, 20. One end 23 of the mandrel is attached to a stub shaft 17 by a clamp 22, the other end is connected by a coupling 25a to a stub shaft 18 which may be engaged by a dog clutch 52. The mandrel 14 carries a perforated swaging head 50, and is connected by a pipe 60 to a pump which extracts water through the head 50. The rollers 3 are mounted on shafts 4 adjustable laterally to accommodate different moulds. The bearings 15, 16, 19, 20 are all adjustable vertically and laterally to centre the mandrel in the mould. The bearings 19, 20 are carried by columns 39 which are adjustable vertically in unison by screws actuated by worm wheels 46 on a shaft 45 operated by a hand wheel 44. Springs are provided in the columns 39 to allow the bearings to yield upwardly. A similar shaft 45 is provided on the other side of the machine to adjust the bearings 15, 16. The columns 39 are mounted in bases 26, 27, 28 which are movable laterally on cross-shafts 29 and 34 and are actuated by threaded shafts 36 which are rotated in unison from shaft 38a. The base 28 is also movable longitudinally on rods 32 by means of chains 53. In operation, a preformed sheet of fibre or asbestos cement is wound on the mandrel 14 either before or after it is in position in the mould. The mould is rotated and one edge of the sheet is caused to drop on to the mould and thus be drawn off the mandrel. The bearings 19, 20 are then lowered to cause the mandrel to roll on the pipe and compact it. The mandrel is centred again and supported on bearings 15, 16. The clutch 52 is engaged and the chains 53 are operated to draw the mandrel 14 through the mould. During this movement the head 50 swages and dehydrates the pipe. The mould is finally spun at high speed for drying and setting.

Title: Antibiotic and its production
Filed: 1952-11-26
Abstract: A new antibiotic, amphomycin, is produced by cultivating Streptomyces canus, which is described, or a mutant thereof, in an aqueous, nutrient containing carbohydrate solution under submerged aerobic conditions at e.g. 24 DEG  to 30 DEG  C. for 2 to 7 days and pH 7.0 to 7.2.  Specified carbohydrates are starch, sugars such as glucose, sucrose and lactose, glycerol, insulin and dextrin.  The medium also contains (a) nitrogen source, e.g. casein and amino acids, fish meal, soybean meal, meat extracts, corn-steeping liquor, wheat steeping liquor, whey, brewers yeast, cottonseed meal, lactalbumin, distiller's solubles, liver cake, urea, nitrates, ammonium compounds and others; (b) mineral salts, e.g. sodium chloride, potassium phosphate, magnesium sulphate, sodium nitrate, and (c) buffers.  The antibiotic is recovered by adjusting the filtered or unfiltered broth to approximately pH 2.0 by, e.g. hydrochloric acid and extracting with butanol, especially n-butanol, or pentanol.  The sodium salt is recovered by extracting the organic solvent extract with water containing sodium hydroxide to pH 7.3 to 7.4.  Further purification involves one or more of the following steps: (a) treatment of solutions especially organic solvent solutions with activated carbon; (b) formation of Reinecke's salt; (c) precipitation by means of a non-solvent, e.g. ethyl acetate; (d) precipitation at the isoelectric point namely pH 3.3 to 3.6.  Amphomycin is effective against B. mycoides, B. aureus, M. tetragenus, Staph. aureus and B. subtilis; it is amphoteric forming salts with acids and metals; it is soluble in water except over the range pH 3.0 to 4.0; soluble in methanol in both acid and salt form, soluble in alcohols in acid form only; is extractable from water of pH 2.0 by butanol or pentanol but not by methyl isobutyl ketone, benzene, ether, ethyl acetate or amyl acetate; forms ammonium and Reinecke's salt; absorbs ultra-violet light only in the 210-230 m  region; exhibits negative response to ninhydrin, Sakaguchi, Molisch and Ehrlich-Pauly tests; is stable for at least 10 days in aqueous solutions of pH 2 to 10; it contains carbon, hydrogen, oxygen and nitrogen.
