Title: Improvements in or relating to the production and treatment of filaments, yarns, ribbons, films and other spun products made of or containing cellulose esters or ethers
IPC: D01F2/28
Filed: 1930-09-08
Abstract: Artificial threads, films, &c., made of or containing cellulose acetate or other cellulose esters or cellulose ethers are improved as regards their properties in particular their extension or tenacity, or are conditioned by treatment at relatively elevated temperatures with substances which at ordinary temperatures do not exert a solvent or swelling action upon the cellulose derivatives, but which are capable of swelling, plasticizing or even dissolving them at relatively high temperatures. Such substances are glycerine, glycols such as ethylene glycol, diethylene glycol, propylene glycol, trimethylene glycol, and 1.2- and 1.3-butylene glycol; ethers of glycerine or other higher polyhydric alcohols. With glycerine good results are obtained at temperatures of 120-170 DEG C., particularly at 140-160 DEG C.; with diethylene glycol, at 75-90 DEG  C.  The treatment may be such that the materials are permitted to shrink; or tension may be applied to prevent shrinkage, or the materials may be stretched, for example, to 200 per cent or more.  Without stretching there is an improvement in the extension of the materials; with stretching, the tenacity is increased.  To the glycerine, glycols &c. there may be added water, benzene or other hydrocarbons, alcohols, or other inert substances, or solvents or strong swelling agents such as acetic or formic acids, lactic acid, diacetone, alcohol, acetone, ethers, esters or ether-esters of glycols, dioxane, phenols, acetins, dichlorethylene, ethyl lactate, diethyl lactate; or such agents may be carried by the threads &c. to be treated.  The treatment may be applied to the materials in the form of banks or on bobbins, beams etc.; or during a rewinding operation, or while passing from a dry or wet spinning machine. Stretching may be effected by passage round a series of rollers moving at increasing peripheral speeds.  After treatment in the glycerine &c. bath, the threads &c. are passed over guides or through rollers to remove surplus liquid, and they may then be washed.  Collection on cap spinning devices facilitates the final drying.  Specifications 277,089, 323,790, 333,949 and 336,217, [all in Class 2 (ii), Cellulose &c.], are referred to.

Title: Improvements in bricks, tiles, slabs or the like for building or decorative purposes
IPC: C04B20/10
Filed: 1933-09-29
Abstract: A cement-sand composition for bricks, tiles, and slabs with a glazed surface, or for use as a glazed surfacing material on concrete or rough brickwork, is prepared by first boiling fine sand in an aqueous solution of an alkaline salt such as carbonates, hydroxides, silicates, aluminates, and phosphates, whereby the particles of silica are coated with a gelatinous silicate before mixing with the cement.  The cement may be of the Portland, aluminous, oxychloride, or phosphate variety. Alternatively, the heat for the reaction may be obtained by adding quicklime to the solution.  Kaolin, accelerators, and gas liberators may be added.  Examples are: (1) 50 galls. fine sand containing 10 per cent of particles of the fineness of flour of natural or precipitated silica, 1 gall. common soda, and 18-19 galls. water are boiled from three to ten hours; 90 lbs. of this treated sand are mixed with 40 lbs. cement, and colouring matter and a small quantity of sulphur added with lukewarm water to form a plastic mass. To remove gases, 2 pints of 10 per cent solution of ammonium chloride are added, with 5 to 15 pints of an accelerator made by dissolving 20 ozs. potash alum in 10 pints water and adding it to 20 ozs. common soda in 10 pints water.  The sand mixture stands for five to thirty minutes to gelatinize, and is cast in moulds lined with glass or hard steel.  The mixture sets in one to two days in air.  The thickness may be increased by a layer of ordinary concrete, and fissures may be imitated by applying streaks or dots of oil on the pallets.  For cheaper products, untreated sand may be added to the mix, producing a friable mass for pressed work; (2) 60 lbs. kaolin, 10 lbs. common soda, and 20 galls. water are boiled for several hours; 1 gall. of this solution is mixed for three minutes with 100 lbs. fine sand and 95 lbs. quicklime, and the mass is put in closed silos for twenty-four hours; the heat of hydration raises the temperature to 180 DEG  F., and sodium silicate is formed.  The treated sand is then mixed with Portland cement in the ratio 8 to 1, and colouring matter may be added; (3) 100 lbs. sand are boiled for one hour with 1 lb. common soda in 2 galls. water, and there are added 1 lb. china clay and 5 lbs. quicklime.  After twenty-four hours the mass is made semiplastic with cement; (4) 100 lbs. sand, 5 lbs. quicklime, and 3 lbs. china clay are mixed dry; 1 gall. of 1 per cent aqueous solution of soda is added and mixed for three to five minutes, and after twenty-four hours cement is added as in Example 3.

Title: An electrical cut-out
IPC: H01H87/00
Filed: 1920-09-22
Abstract: 172,446. Illingworth, W. H. Sept. 22, 1920. Mercury cut-outs. - In mercury-thread resettable cut-outs of the kind described in Specifications 121,305, 138,439, 159,917, and 166,286, in order to improve the action under heavy shortcircuits, the displaced mercury is trapped by means of a valve, in the upper part of the casing from which it may be liberated, to restore the column, by opening the valve; the restoration may be assisted by a pump. In the form shown in Fig. 1, a passage b<8> in alignment with the restricted passage a<2> is formed in the valve which consists of a plug, spring-pressed on to the seating b<10>. On overload, the ejected mercury is trapped above the valve and may be re-admitted by raising the valve from its seating by an external handle b<6>. Several inclined passages may be formed in the valve head, and the restoration of the mercury column may be assisted by a pump mounted on the hollow lower terminal portion B' and communicating with the mercury therein. A portion of the valve may be recessed to constitute a shallow pocket between it and the seating; a film of mercury collects in the pocket and ensures good surface contact. In a modification, Fig. 3, the cap b<3> on the upper terminal portion is formed with an inclined inner end D closed except for the central orifice d<1>, through which the mercury is ejected to be tripped in the lower part, from whence it may be released by rotating the cap until ports d<2>, d<3> register. A pump e<7> ensures restoration of the column. The construction is applicable to the form in which a number of columns in parallel are located in the same container. The restricted column may be constituted by a quartz tube forming a lining to the hollow insulating body part A.

Title: Apparatus and method for sealing a thermoplastic top to a tube body
IPC: B29D23/20
Filed: 1962-07-13
Abstract: 1,007,780. Moulding collapsible tubes. PROCTER & GAMBLE CO. July 13, 1962 [July 13, 1961], No. 27036/62. Heading B5A. A pre-formed thermoplastic top is sealed to a tubular body by rotating the top and body while heating their edge portions, telescoping them together, and restraining the outside of the joint while pressing it from within. As shown, a top 20 having an inturned skirt 22 is a push-fit on the tip 40 of a shaft 39, and a tubular body 23, which may be plastic or a plastic-metal foil laminate, fits on to a mandrel 29. The mandrel 29 forms the upper part of a shaft 30, and by means of a motor connected to a chain 38 (Fig. 14) a shaft 32 is rotated, which rotates coaxial shafts 30, 39. By means of a pin 33 and slot 34 the shaft 30 can move vertically relative to driving shaft 32, and a similar arrangement permits movement of shaft 39 relative to mandrel 29. Mandrel 29 is moved by a cylinder 44, and Fig. 14 shows the mandrel raised to a limit set by a stop 48 engaging a collar 46 on a rod 45. In that position gas burner heads 49, 50 are used to heat the appropriate sections of the top and body (Fig. 12), heat being directed at the skirt 22 of the top, while the assembly rotates as described above. The burner heads are withdrawn, and a solenoid 47 is energized to withdraw stop 48. The mandrel is raised further, the spacing between top and body being maintained until the top 20 bears against a tapered opening in an anvil 77. The top is thus telescoped into the body. A plate (Fig. 10, not shown), is then rotated, in which the upper ends of pins 67-70 engage, so that those pins (Fig. 9) slide outwards, causing jaws 55-58, mounted on levers 59-62 pivoted at 63-66 to close around the body 23. A solenoid 84 is then de-energized, closing an opening 81a beneath shaft 39, and a cylinder 82 is actuated to raise shaft 39 slightly. This raising causes a shoulder 41, integral with tip 40, to force the skirt 22 of the top 20 outwards against the body 23, and the seal quickly cools. Specification 1,007,779 is referred to.

Title: Electric graphitizing furnaces
IPC: H05B3/60
Filed: 1957-08-28
Abstract: <PICT:0835953/III/1> Carbonaceous bodies, e.g. bars 14, are graphitized in an electric furnace having a refractory shell with a gas space at the top communicating with a gas removal conduit and containing a pair of electrodes passing current through a core of granulated carbonaceous material in which the bars 14 are embedded and in which at a lower level D than the bars are several tubes 20 vented at 22 for introducing a reactive gas to remove impurities from the bars 14.  The shell encloses a recessed furnace bed composed of a mixture of granulated coke and impalpable carbon powder offering a high resistance to gas flow, a core bed on the floor of said recess surrounding the tubes 20 and supporting the bars composed of granular graphite providing higher gas permeability than a granular graphite interposed between the bars 14, and a granular cover 26 composed of a relatively highly gas carbonaceous material above the bars 14 and a relatively low gas permeable material 28 above the furnace bed adjacent the recess and abutting the material 28.  The granular carbonaceous cover is in the form of a triangular truncated prism, with a narrow top gas outlet 32. Gases, e.g. nitrogen or a halogen-containing gas such as carbon tetrachloride or difluordichloromethane are admitted through a narrow tube 16 of non-crystalline carbon into a wider tube 18 of non-crystalline carbon and hence into a still wider tube 20 of graphite, whence the gas issues through slots 22 arranged 30 degrees below the horizontal. When the power is turned on, nitrogen is admitted until the charge reaches 1000 DEG  C.; and on increase in power to reach 1700 DEG  C. difluordichloromethane is admitted and the temperature is raised to 2500 DEG  C.  After cooling to 2200 DEG  C., nitrogen is admitted until the temperature falls to 1000 DEG  C.  The product may be used for electrolytic anodes for mercury cells, thermic anodes, arc electrodes for spectrochemical analysis or as a moderator in thermal reactors.
