Title: Production of sulfur dioxide from sulfur and sulfur trioxide
IPC: C01B17/54
Filed: 1954-05-27
Abstract: Sulphur dioxide is produced by introdducing sulphur and sulphur trioxide into a liquid reaction medium comprising 10-90 per cent of sulphur dioxide, fractionating the sulphur dioxide produced, recycling a portion, and recovering the remainder.  As shown liquid sulphur trioxide and sulphur are passed through conduits 11 and 16 respectively into reaction mixture 18 in vessel 21 maintained e.g. at 260-720 DEG F. <PICT:0765796/III/1> and 185-700 p.s.i.g. and a mixture of sulphur dioxide and sulphur trioxide is evolved which is rectified in column 20.  The overhead gas, mainly consisting of sulphur dioxide passes through conduit 27 and heat exchanger 28 and is collected in drum reflux 30, uncondensibles passing out through conduit 31.  A portion of the condensate is returned to column 20 as external reflux through conduit 32, and the remainder passes through conduit 34 to a second similar rectifying column 51.  Bottoms, consisting mainly of sulphur trioxide are returned from accumulator 49 to reaction vessel 21.  Draw-off is provided in vessel 21 to prevent build-up of undesirable polymers, water, sulphuric acid &c. A reflex ration of 8:1 may be employed in the first column (giving a sulphur dioxide concentration in the solution of about 10 per cent). At higher reflux ratios sulphur dioxide may be externally refluxed via conduit 52.

Title: Improvements in or relating to loose-leaf visible indexes
IPC: B42F13/00
Filed: 1931-05-28
Abstract: 375,964. Visible card indexes. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. May 28, 1931, No. 15700. [Classes 16 and 146 (i).] In visible indexes arranged in loose-leaf book-form the thickness of paper in the marginal area is regulated to compensate for the thickness of the binding devices and so that the top cover can be parallel to the bottom cover. As applied to sheets adapted to be mounted in a loose-leaf binder as described in Specification 356,452, the sheets are cut away adjacent to the binding edge 2 so as to leave lugs 1 perforated or notched to engage binding studs mounted on backing sheets one of which is provided for each set of sheets. The total width of the lugs 1 relatively to the overlap between adjacent sheets determines the maximum thickness of paper along the margin adjacent to the binding devices. The sheets may be similarly treated at the free edges to compensate for the thickening effect of index tabs. In order that each unit carried on a backing sheet may be of uniform thickness, the backing sheet is provided or formed on both faces with protuberances increasing in thickness towards the top and bottom edges thereof by affixing embossed strips thereto in the manner described in Specification 337,468, [Class 146 (i), Filing paper &c. sheets]. The binding studs may be mounted on strips instead of backing sheets. The edges 1a of the lugs may be perpendicular or inclined relatively to the sheet edge.

Abstract: 506,872. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 26, 1938, No. 15764. Convention date, May 27, 1937. [Class 38 (iv)] [Also in Group XIX] Concentration ; viscosty.-Apparatus for regulating the viscosity of a fluid comprises a container 1 for the fluid, a pump 5 for withdrawing fluid from the container and forcing it through an orifice 12, a stand pipe connected to the orifice for fixing the pressure head on the fluid there, and means responsive to the rate of flow of the fluid through the orifice for controlling means to regulate the viscosity of the fluid. The flow may be measured by placing an electric heating coil 13 round the flow pipe 9 from the orifice 12 and placing coils A and B around each end of pipe 9 which forms a Wheatstone bridge in association with the divided resistance 17. The difference in temperature between coils A and B will be proportional to the flow of fluid therebetween and the changes in their electric resistance will be proportional to these temperature changes. The lack of balance of the bridge produced by these resistance changes operates a controller 19 which regulates a pump 3 which adds solvent to the mixture in tank 1 in order to bring the viscosity back to the required amount.

[Class 37] A dry contact rectifier, in which a selenium layer is used as one electrode and is separated from the counter electrode by a blocking layer, is formed by applying the selenium in a liquid state to a carbon support. The carbon support may be in the form of a block to which a lead may be attached or may be a layer of carbon applied to a roughened brass or other metal plate by rubbing or from a carbon suspension in a binding agent ; in the latter case, the dispersion medium may be removed by heat. A selenium layer of suitable thickness is applied to the carbon layer and is heated to transform it into the conductive crystalline state. The blocking layer may consist of polystyrene which is applied to the selenium layer and the counter electrode which can be applied by spraying to the blocking layer may be of Wood's metal or other readily fusible allov. In a modification, barium tungstate in finely divided condition may be mixed with the liquid selenium before this is applied to the carbon support. Upon heating, the selenium vaporizes superficially leaving a film of barium tungstate as the insulating blocking layer. Cadmium may be used as the counter electrode. In order to prevent the formation of undesirable films when the carbon layer is carried by a metal support, the latter is provided with an anticorrosion layer. The support 13, which may be of copper or of aluminium when a number of series-connected rectifying units are used as a high-tension rectifier, is given electrolytic coatings 14, 15 of nickel and chromium, serving as anti-corrosion layers. The selenium layer 17 is applied over the carbon layer 16 and a polystyrene layer 18 is provided which may be applied from a solution in benzene. The counter-electrode 19 is of Wood's metal. Chromium, nickel, platinum or gold may be used for the anti-corrosion coating.

Title: Improvements in electro-plating apparatus
IPC: C25D21/12
Filed: 1954-05-31
Abstract: 767,136. Automatic control systems for electro-plating apparatus. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and STEVENS, S. A. May 25,1955 [May 31,1954; July 8, 1954], Nos. 16010/54 and 19988/54. Class 38 (4). In an apparatus for electroplating continuous steel strip, the output of generators 6, 11, Fig. 1, representing the plating current and strip speed respectively, are differentially applied over an amplifier 15 to a reversible servomotor 16. The motor positions a regulator 5 in the A.C. input. to rectifiers 4, supplying the plating current, so that the latter is varied to maintain a constant ratio of plating current to strip speed and thus a constant plating thickness. The generator 11 is driven at strip speed from a roller 12 and has a permanent magnet field, a resistor 14 being adjustable for setting a desired plating thickness. Generator 6 is driven at constant speed by a motor 7, and has its field excited, from a shunt 9 in series with the plating bath, in accordance with the plating current. A feedback signal is applied to amplifier 15 from a generator 17 responsive to the speed of motor 16. In a modification, Fig. 2, a synchronous motor 18 drives the generator 6, and, in order to compensate for frequency fluctuations in the supply to motor 18, the speed-responsive generator 11 has a field 19 energized from the output of a further generator 20. The latter has a permanent magnet field and is driven by a second synchronous motor 22 having a common supply with motor 18. Since both the opposed outputs of generators 6, 11 are responsive to frequency fluctuations in the common supply to motors 18, 22, the input to the motor 17 is independent of such variations. In order to compensate for inherent anomalies in the generator characteristics, the two generators 6, 20 are substantially identical and may be connected in series opposition in the input to amplifier 15. In this case, as shown in Fig. 3, generator 20 has a field 25 energized by the output of generator 11, so that its output is in turn speed responsive. Resistors 14, 24, 25 in Figs. 2, 3 allow adjustment of the plating thickness.

The dynamic unbalance signal at each of the bearings 6, 7 (Fig. 1) of a rotor 1 is mixed in Hall plate generators 9 (10) with sine (cosine) reference signals obtained from a synchronously driven generator 5, and the combined output signal is fed through an A.C. filter 11 (12) to give a D.C. voltage representing one component of the unbalance mass. The two components are fed to the deflecting plates of a CRO 13 to indicate the magnitude and phase of the unbalance mass at each bearing. In a modification the D.C. signals modulate a carrier voltage which is amplified and phase rectified before connection to the CRO.

Title: Improvements in or relating to the pulping of cellulosic material
Inventor: HOOD NORMAN ROY
IPC: D21C3/26
Filed: 1956-05-24
Abstract: Cellulosic material is pulped by subjecting the material to a first digestion at a temperature below the boiling point and at atmospheric pressure with a liquor containing 0.5-7% weight per volume of sodium hydroxide (or its equivalent in terms of Na2O), with or without sulphidity, for a period of time depending inversely upon the temperature, the liquor to material ratio being not less than 3:1, diluting if necessary, fiberizing the digested material by a rubbing action, and subjecting at least a portion of the resulting material to a second digestion at a temperature below the boiling point and at atmospheric pressure with liquor similar to that used in the first digestion step, the liquor being removed from the pulp produced by the first and second digestion steps or, in the case where all the material is subjected to a second digestion, from the pump produced by the second digestion step.  "Sulphidity" is defined as <FORM:0834006/IV (a)/1> per cent, both Na2S and NaOH being expressed as Na2O, and "fiberizing" is the mechanical treatment applied to resolve the softened aggregates into a fibrous pulp.  The liquor to material ratio is the ratio by weight of the sum of moisture in the raw material and the added cooking liquor to the oven-dry weight of the raw material.  After the first digestion the material may be fiberized, washed and screened, only the rejects from the screening step being re-cycled for a second digestion at the location of the first digestion.  Alternatively, after the first digestion, the material may be washed, fresh liquor added, and all the material fiberized and then digested in a second digester, the liquor removed after the second digestion being concentrated and returned to the first digester.  The process is particularly applicable to the pulping of graminaceous cellulosic material, e.g. esparto grass, juncus maritimus, wheat straw, rice straw, sabai grass, bamboo and bagasse obtained from sugar cane, but it may also be applied to hardwoods, e.g. birch or aspen, and bast and leaf fibres.  After the second digestion the pulp may be washed, screened, bleached and cleaned and used for the manufacture of fine papers, but if the bleaching is omitted, pulp suitable for the manufacture of board is obtained.
