Title: Improvements in and relating to electric control systems employing resonance relays
IPC: H01H51/32
Filed: 1937-06-09
Abstract: 485,419. Electric control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 9, 1937, No. 16018. Convention date, June 12, 1936. [Class 40 (i)] In a step-by-step selector arranged to operate different circuits in response tc impulses of different frequencies, the stepping magnet R is normally tuned by a condenser C<1> but in response to the corresponding frequency the magnet R steps the switch St through the intermediary of a vibrating reed Z, to switch in a condenser C<2> to tune the magnet to a new frequency which may then be transmitted to operate the switch a further step. Similarly condenser C3 is switched in ready for a third operation. Instead of switching in different condensers, different windings of the relay R may be connected in circuit. The individual devices selected by the selector may be provided with time-delay devices in order to prevent operation during the passage of the selector past the various selecting positions. Furthermore, the arrangement may be such that the switch is brought into each switching position by a number of impulses of the corresponding frequency. The selector may be operated by impulses transmitted over a power network.

Title: Improvements in or relating to thick-walled tubes wherein large quantities of heat are produced or introduced
IPC: F17C1/12
Filed: 1923-06-22
Abstract: The stresses to which are subjected the walls of very thick walled tubes within which large quantities of heat are produced are diminished or eliminated by dividing the internal surface into sections by means of grooves in such a manner as to permit easy expansion of the internal layers without diminishing the resistance of the tube to pressure; the internal surface may for example be provided with one or more continuous or discontinuous helical grooves.  Additional protection may be afforded by lining the tube with heat-insulating material, for instance by inserting a thin-walled tube wrapped round with asbestos.  When it is only necessary to guard against local temperature changes the insulating lining alone may be used.  The invention is particularly applicable in the construction of tubes for carrying out the synthesis of ammonia under "hyper-pressures."

Title: Improvements in and relating to the recovery of sugar
IPC: C13B20/18
Filed: 1953-06-15
Abstract: The precipitate obtained on direct current electrolysis at room temperature of sugar-containing liquors or juices is used for soil improvement.  The electrolysis causes precipitation of some of the dissolved salts, and, by change of pH, precipitation of suspended organic matter also.  According to an example, a 25 per cent solution of blackstrap molasses is electrolyzed, both electrodes being aluminium, and the precipitate so produced is filtered or centrifuged from the sugar solution.  The precipitate may be restored to the original degree of acidity, and so be rendered soluble.ALSO:In extracting sugar from sugar-containing liquor or juice, the liquid is treated at room temperature, after dilution if necessary, by electrolysis with a direct current in order to precipitate some of the dissolved salts and, by change of pH, to bring down suspended organic impurities, and thereafter the liquid is clarified by physical means.  The electrolysis may be repeated.  After removal of the precipitate, the liquid may be treated with both cation and anion exchangers, whereby inorganic impurities are removed and sucrose is inverted.  According to an exapmle, a 50 per cent solution of blackstrap molasses was electrolyzed, both electrodes being iron, and the liquid was decanted, filtered, and decolorized by animal charcoal.  According to another example, a 25 per cent solution of blackstrap molasses was electrolyzed, both electrodes being aluminium, the liquid was decanted, filtered and decolorized by activated charcoal, the decolorized liquid was passed through cation and anion exchange resins and was then concentrated in vacuo to a product of 65 per cent invert sugar content.

Abstract: 358,469. Drain-making apparatus ; couplings for tractors. SMITH, A., SMITH, F. R., and SMITH, A., Maygate, Littlemill, near Patna, Ayrshire. May 29, 1930, No. 16560. [Class 6 (i).] Drain-making apparatus comprises means for cutting the soil in one continuous flat-bottomed ribbon, for elevating the cut soil, for mechanically placing tiles or pipes in the trench formed, and for continuously replacing the soil on the tiles or pipes. Means may also be provided for stopping the pulling tractor when obstructions are encountered. Inclined discs B and coulters C carrying a horizontal cutter D are mounted on runners A which rest on the ground surface. The tops of the discs and coulters are wider apart than the bottoms and the backs than the fronts. The coulters are bevelled so that the sharp edge is at the inner surface. The soil cut by the discs B, coulters C, and cutter D passes on to an inclined trough E, or a belt conveyer, and is carried up to a height above the ground level and then down again into the trench. The tiles Z are carried in a magazine supported by an idle wheel and are fed by hand on to an inclined plane 1, Fig. 5, leading to a double hinged platform 2 below the elevated part of the trough E. The tiles slide down the inclined plane into contact with a stop bar 4 on the far side of the hinged platform 2, the parts of which are normally held horizontal by springs. Two endless chains O driven from a ground wheel J carry pins S which engage the tile Z on the platform 2 and push the platform parts downward to allow the tile to pass through. The next tile is stopped by curved projections 7 on one of the platform parts until these have returned to the horizontal position. The falling tile is supported on the pins S and carried downwards into the trench. It is then positioned by a grooved roller U carried by spring-controlled arms V, and is pressed backwards against the tile last deposited by a spring buffer T carried by a lever actuated by the pins S. The whole apparatus is suspended from a carriage X carried on road wheels Y. To guard against damage by obstacles the pull of the tractor is effected through the spring shackle shown in Fig. 7, one part of the shackle being provided with an insulated terminal 14 connected with the magneto of the engine of the tractor and the other with an adjustable earthed terminal 16. When the pull is excessive the two terminals come into contact and earth the magneto and thus stop the engine. According to the Provisional Specification a rear roller may be provided for compressing the soil in the trench, and a coulter may be movably mounted so as to actuate a contact breaker when the lower end is stopped.
Patent GB-563723-A (GB)
Title: Improvements in or relating to flexible sheet materials
IPC: D06M15/07
Filed: 1942-11-24
Abstract: Composite flexible sheet materials are made by coating, impregnating, or cementing together sheets of textile fabric, paper, or like sheet materials with a cellulose nitrate composition containing a heat treated partially oxidized drying or semi-drying oil having a normal iodine value greater than 135 and an anti-oxidant which protects the oil against progress of further oxidation towards linoxyn-like products.  The heat-treated oil may be derived from linseed, oiticica, tung, or Perilla oil.  The products known as bodied or blown oils may be used.  The proportion of oil in the composition may be several times that of the cellulose nitrate.  If a pigmented composition is desired, and the oxidized oil is too viscous to be used for grinding the pigment, a proportion of castor oil, less than that required for softening the cellulose nitrate, may be used.  As anti-oxidant there may be used oil of cloves, citric acid, an aryl boric acid, a diaryl guanidine, eugenol, b -naphthol, di-o-cresylol-propane or its formaldehyde condensation products, tannic acid, guaiacol, catechol, hydroquinone monoalkyl ethers, creosole, o- or p-cyclo-alkyl phenols, o-or p-alkyl phenols, dialkyl phenols, aldehydeamine condensation products, e.g. products from acetaldehyde and a mixture of a - and b -naphthylamines, aryl ethers of alkylolamines, e.g. piperidine - dimethylamino - methylene - dicresylol-propane.  In an example, a cotton sheet is coated with a composition comprising cellulose nitrate, bodied linseed oil, pigment, oil of cloves, acetone, methylated spirits, benzol, and butyl acetate.  Several coatings are applied and the volatile solvents are evaporated after each coating.  A clear cellulose nitrate lacquer is finally applied.  The composition may be embossed in a hot calender to provide an imitation leather.  A thin coloured cellulose nitrate lacquer may be applied after embossing.  In another example, two dyed cotton sheets are coated with a cellulose nitrate composition containing bodied linseed oil pigment and oil of cloves. While the coating on one of the fabrics is still wet with solvent, the two fabrics are pressed together and the remaining solvent is evaporated.  The compound fabric obtained may be used for wind- and weather-proof clothing.
