Filed: 1949-10-07
Abstract: 665,335. Automatic voltage and current control systems; rectifying. STANDARD TELEPHONES & CABLES, Ltd. Oct. 7, 1949, No. 25798/49. Classes 38 (ii) and 38 (iv). An A.C. or D.C. supply system in which constant voltage control is superseded by constant current control if a predetermined load current is exceeded. The output voltage of a rectifier 6 is normally maintained constant by means of a saturable reactor 8 in series with the A.C. supply to the rectifier transformer 5. The saturation of the reactor 8 is controlled by a parallel connected carbon pile 11, the control winding 12 of which is connected across the output terminals via a rectifier 18. A rectifier 14 is in series with the A.C. supply to provide the D.C. saturating current and is shunted by a current transformer 15, the output of which is applied via rectifier 16 to the control winding 12. As long as the current component is smaller than the output voltage, rectifier 16 is blocked, rectifier 18 conducts, and constant voltage control is effected. If the current rises above a predetermined value, rectifier 18 is blocked, rectifier 16 conducts, and constant current control is effected. For an A.C. system, the main rectifier 6 is omitted and a rectifier is added to the circuit of the control winding 12. In a modification, Fig. 4 (not shown), in a system in which the output of the rectifier is controlled by a relay controlled reversible tap changing motor, the relay winding is connected across the output via one rectifier, and to the output of a current transformer via an opposing rectifier, the action being as before.

[Class 140] Fibrous mineral wool, such as glass, slag, or rock wool, is bonded with an agent consisting mainly of petroleum resin by application of a dispersion of the resin in water containing alkaline caseinate and excess of casein other than that required in the caseinate for emulsification purposes. A self-sustaining rigid, semirigid or flexible mass or bat, which is suitable for insulation in dwellings, is produced. The petroleum resin is heated and stirred into a solution of ammonium or other alkaline caseinate or the resin may first be dissolved in a solvent such as white spirit or paraffin and then emulsified. Preservative for the casein, fireproofing agents such as ammonium chloride and borax, and metallic driers such as cobalt naphthenate may be added. Preferably the aqueous dispersion is sprayed on to the fibres as they are deposited in a continuous matformation on a conveyer which then carries the mat under compressing means, such as a roller to reduce the mat to the desired thickness and through an oven where a blast of hot air dries the dispersion by evaporation and oxidation. Specification 550,833 is referred to.

Abstract: 815,044. Cable terminals. AMP Inc. Aug. 16, 1957 [Aug. 20, 1956], No. 25958/57. Class 38 (1). [Also in Group XXII] The ferrule 10 of a ring-tongue type connector has a central bore 20 for receiving a conductor 18 and is provided with an annular chamber 26 communicating with its outside wall. A sleeve M (Fig. 2) is placed around the ferrule to form a fluid-tight chamber 14 on the outside of the ferrule. Sealing means 30, 32 prevent escape of fluid. Pressure fluid is applied to the chambers 14 and 26 the latter being enlarged to form the connection as shown in Fig. 4. Instead of applying fluid pressure to a chamber within the walls of the ferrule it may be applied to a chamber formed on the outside of the ferrule by the sleeve M or the ferrule may be mounted in a mould which forms a chamber on the outside of the ferrule. In another embodiment the chamber 26 is filled with an explosive powder which is detonated to form the connection, the outer wall being made thicker to prevent its expansion or a sleeve similar to the sleeve M may be used. In another embodiment the ferrule is made in two parts 34, 36 (Fig. 7) which form two fluid-tight chambers 126, 128 within the ferrule wall. The part 34 has a wider bore at the end to accommodate the insulation of the conductor. The connection is effected by applying fluid pressure to the chambers after which an insulating sleeve 130 is placed over the ferrule. In a modification of this latter embodiment the two chambers are merged into one as shown in Fig. 8.

Abstract: 412,534. Compound sheet materials; paper. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Sept. 19, 1932, No. 26012. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 30, 1932]. [Classes 96 and 140.] Decorative plates or panels are made by applying a decorative layer which consists of artificial resin, or of paper or fabric impregnated with artificial resin, to a backing produced by mixing fibre pulp with a binding agent comprising clay, water, and a bituminous substance, the layers being united by hot pressing. The binding agent may be made by heating a suspension of clay in water to a temperature above the melting point of the asphalt to be used. The latter is then melted and added gradually, while stirring. The fibre pulp is then added, and the whole passed through a paper making machine. A small quantity of sodium silicate or aluminium sulphate may be added. The decorative layer of paper or fabric is impregnated with a solution for example of phenol formaldehyde resin and dried, and is then united to the backing in a hot press at 140 to 170‹ C. An intermediate layer of paper impregnated with artificial resin may be used to prevent the asphalt from affecting the surface layer, and to prevent warping, a further layer of paper impregnated with artificial resin may be united to the reverse side of the backing. In an alternative process, a layer of paper or fabric is placed over the backing, and a mass of artificial resin, preferably coloured, is applied and pressed on. The mass of artificial resin may alternatively be pressed directly on to the backing.
Patent GB-260744-A (GB)
IPC: G01G19/00
Abstract: 260,744. Molins, W. E. Oct. 8, 1925. Recording particular operations. - In an apparatus for enabling the attendant to check and record the weights of cigarettes, or the number per oz., from time to time, as they are delivered from a cigarette-making machine, a paper web driven continuously from the cigarette-making machine is drawn from a reel 28, Figs. 1 and 2, by feed rollers 24, 27. the length of paper thus fed being an indication of the number of cigarettes being manufactured by the machine. The paper web passes between elements 30, 31, Fig. 2, secured to a lever 32 which may be rocked in the direction of two needles 90, 90<a>, by means of a lever 34, link 35, lever 36, and cam 39 driven at the correct moment by a frictional connection with a constantly-rotating shaft 15. The needle 90 is carried by an arm extending from the weigh beam and is consequently positioned according to the weight of cigarettes in the scale pan 83. The needle 90<a> is stationary and serves to mark the zero position. Normally a finger 47, Fig. 9, projecting from a rock shaft 48. Figs. 2 and 9, prevents rotation of the cam 39. When, however, a lever 53, Fig. 1. is liberated from a catch 58 by the attendant, the lever rises under spring action, and a connecting link 52 rocks the shaft 48 and liberates the cam whereupon the lever 32 is rocked and the paper web is pressed upon the needles to give a permanent record of the weighing. To prevent two weighing operations being recorded before the paper web has moved sufficiently, the lever 53 is prevented from prematurely rising to effect the second operation if attempted by the attendant by the arrangement shown in Fig. 9, wherein the shaft 48 is capable of longitudinal movement and is pressed to the right by a spring 61. In the righthand position a pin 64 lies upon the side of a bearing 49 and prevents the rod 53 from rising until the cam 39 has revolved sufficiently to cause a pin 46 thereon to engage the finger 47 and thus draw the shaft 48 to the left-handed position shown. When the apparatus is used with a cigarette-making machine the speed of which may be varied by the operator, a time mechanism connected to the rocking arm 32, Fig. 2, may be arranged to mark the paper web at regular intervals of time so that, by comparison with horizontal lines on the web indicating the number of cigarettes manufactured, the speed at which the machine has run at various times may be checked.

Title: Improvements in the manufacture of esters of cellulose
IPC: C08B3/22
Filed: 1935-09-24
Abstract: Cellulose is esterified in presence of a solvent for the ester and with aid of a polybasic inorganic acid or acid derivative thereof as catalyst.  To the primary esterification solution, while it still contains free inorganic acid, there is added a salt of a monobasic inorganic acid with a metal capable of forming with the polybasic acid a salt which is soluble in the solution, the solution is allowed to stand until the cellulose ester is of the desired acyl content, and the ester is then precipitated.  The catalyst may be sulphuric acid, sodium bisulphate, methyl sulphate, or mixtures of these with each other or with other catalysts such as zinc chloride.  The added salt may be aluminium, sodium, zinc, or tin chloride.  Agents reacting to produce such salts, e.g. aluminium acetate and hydrochloric acid may be used.  The salt may be present in solution in the water which is added to hydrolyze anhydride and to effect ripening.  The acid catalyst may be partly neutralized before addition of the salt, by means of sodium carbonate or bicarbonate. The products have high stability to heat, light, and industrial gases.  They are suitable for the production of artificial threads. In an example, a small quantity of sodium carbonate solution is added to a primary unripened esterification solution of cellulose acetate in order to neutralize some of the free sulphuric acid contained therein.  Aluminium chloride solution is then added.  The solution is ripened and the product precipitated by addition of water.  In another example, zinc chloride solution is added to an unripened primary cellulose acetate solution containing free sulphuric acid.
