Title: Improvements in or relating to vulcanizing moulds for use in the manufacture of hollow articles
IPC: B29D23/24
Filed: 1928-10-03
Abstract: 298,140. Fawick, T. L. Oct. 3, 1927, [Convention date]. Vulcanizing-moulds. - Tyre and like vulcanizing-moulds are mounted within a casing from the interior of which air is exhausted to hold the moulds closed. Steamheated mould sections 10, 12 are mounted on the halves 3, 4, respectively, of a hinged casing. The hinge is slightly flexible, and the meeting flanges 26, 27, of the casing are provided with a rubber packing-strip 29, to ensure a good fit of the mould surfaces. When the casing is closed (as shown), air is exhausted from the interior by a pipe 30 fitted with a three-way cock, by means of which air can be re-admitted for opening; if desired, opening may be facilitated by the admission of air under pressure by a pipe 31. The tyre &c. is expanded during vulcanization by the admission of compressed inert gas through a pipe 33, connected to the valve stem 20 which is held in position in the mould by a grip 23. This supply is controlled by a cock 34 operated by a handle 35, a clutch 36 being provided which can be engaged by a handle 39 for operation when the mould is closed. A modification is described in which two moulds are mounted back to back.

Patent GB-399320-A (GB)
Title: Improved cold bleaching process
IPC: D06L4/70
Filed: 1932-10-13
Abstract: Cotton is bleached in the cold by subjecting the material first to an oxidizing bleach with hypochlorite, then to an intermediate treatment with a solution of an alkali and finally to a further oxidizing bleach with hypochlorite.  In examples (1) raw cotton piece goods desized by means of "Diastafor" are bleached with a sodium hypochlorite solution in the presence of a wetting agent resistant to cotton such as the amyl alcohol ester of sulphophthalic acid.  The goods are rinsed and treated with a sodium hydroxide solution containing Marseilles soap and finally with a hypochlorite bath.  (2) A patterned fabric bearing vat dyestuff effects is treated with javelle liquor, then with a sodium hydroxide solution and finally with a hypochlorite solution.  Specification 399,319 is referred to.
Patent GB-394539-A (GB)
Title: Roasting pyrites fines
IPC: C22B1/10
Filed: 1932-10-13
Abstract: <PICT:0394539/III/1> Finely divided pyrites, marcasite, chalcopyrites, and like sulphide ores are heated to distil off their volatile sulphur and are then roasted with air or oxygen while in gaseous suspension to produce sulphur dioxide and metal oxides. Sintering is thereby avoided.  The distillation may also take place with the pyrites &c. in suspension in a hot gaseous medium.  The hot gases from the roasting operation may be utilized in the distillation. Pyrites fines or flotation concentrates are fed from a hopper 2 through a screw conveyer 3 and inlet duct 4 into a distillation chamber 1 where they are distilled while in suspension in hot sulphur dioxide gases which enter through tuyeres 6, 7 leading from feed pipes 8, 9.  The resulting iron monosulphide is passed by a screw conveyer 16 into a roasting chamber 5 where it is roasted in suspension by means of air or oxygen, if desired preheated, which enters via tuyeres 18.  The iron oxide Fe2O3 or Fe3O4 is removed by a screw conveyer 20.  The hot sulphur dioxide gases pass to the distillation chamber through a duct 10 and the hot gases containing sulphur dioxide and sulphur leave through an exit duct 14.  The heat of these gases may be used to preheat the air or the pyrites.  The pyrites in the distillation chamber should be heated to 500-800 DEG C. which is low enough to prevent sintering.  The temperature of the upper part of the roasting chamber should not exceed the fusing temperature of iron monosulphide, i.e. 850-900 DEG  C.  In the lower part of the roasting chamber the temperature may be up to 1400 DEG C.  The process may be initiated by preheating the roasting chamber with oil burners or by preheating the distillation chamber electrically.  The gases containing sulphur dioxide and sulphur may be burnt to convert the whole of their sulphur content into sulphur dioxide or may be treated with carbonaceous reducing agents such as producer gas, water gas, natural gas, solid carbon and the like or with hydrogen sulphide to convert their whole sulphur content into elementary sulphur.

Title: Improvements in machines for cutting or breaking coke and/or other material
IPC: B02C21/02
Filed: 1934-10-06
Abstract: 425,013. Roller-and-breast mills. GIBBONS BROS., Ltd., Dibdale Works, Dudley, Worcestershire, COOK, N. G., 61, Springfield Grove, Sedgley, Staffordshire, and VERNON, H., 10, Wellington Road, Nantwich, Cheshire. Oct. 6, 1934, No. 28637. [Class 59] In a coke &c. crusher an impact plate or breast is provided with parts adapted to mesh with the cutting teeth or projections on the rotor and diverges above and below the meshing position to form a converging feed throat and a diverging discharge opening respectively. The rotor comprises square or star-shaped plates 9 mounted on a square shaft 10, each plate being separated by a distance piece 13 and the whole of the plates and distance pieces being bolted together by bolts 15. The breast comprises bars 16 spaced apart by distance pieces 17 and bolted together at 18, additional plates 31 with serrated edges may be inserted between the plates and secured to a back plate 29 when a fine disintegration of material is desired. The bolts 18 pass through slots 21 in the casing and are engaged by eye-bolts 22, 24, Fig. 2, the upper eye-bolt 22 being adjustable in a socket in the casing and the lower being movable in a bracket 26 under the compression of a spring 27. A further eye 25 may be made in the eye-bolt 24 to receive the lower bolt 18 for a large adjustment of the lower end of the breast. A similar breast may be provided on the opposite side of the rotor and spaced nearer to the rotor so that material may be crushed to a finer degree without adjusting the position of the breasts by reversing the direction of rotation of the rotor. The rotor and breast may be reversed end-for-end to compensate for wear and individual plates may be moved for this purpose. Material is fed into the hopper 33 and after being crushed falls onto a screen 34. The crusher is mounted on a vehicle and is driven by an engine through gearing, one of the train of wheels being slidably disengaged when desired by a fork movable by a crank. The crusher flywheel is engaged by a clutch and a sprocket on the clutch drives, by means of a chain, a sprocket on a reduction gear engaged with the vehicle wheels.

Title: Improvements in or relating to mercury vapour lamps
IPC: H01J61/28
Filed: 1928-10-09
Abstract: 323,564. Robertson, J. R., and Vielle, J. Oct. 9, 1928. Low - pressure metallicvapour apparatus.- A mercury vapour lamp consists of a long quartz or sodium &c. glass tube 1 having a platform 2, formed of metal or of the material of the tube and provided with fine perforations. The space 3 above the platform is occupied by mercury which may contain finely divided thorium or other radio-active material. A heating coil may be provided in the mercury, the current for the coil being led in at a branch tube 7, or the mercury may be contained in a metal cup having a perforated base, heating being effected by induction &c. Electrodes 5, 6 may be provided in the ends of the tube 1 and a glass or metal grid 8, capable of being heated, may be placed below the platform 2. To facilitate the return of mercury accumulated in the lower part of the lamp, a bye-pass tube connects the space below the grid 8 with that above the platform 2. The tube may be evacuated or contain air or other gas. In operation, the tube is arranged in a vertical position and the finely divided mercury falling under the influence of gravity and heat becomes luminous. If necessary, the luminosity may be increased by the application of a high frequency or steady potential difference between the electrodes 5, 6 or between the electrode 6 and the mercury in the container or the grid 8. To modify the colour of the emitted light, a gas discharge tube containing argon or neon &c. or one such as described in Specification 237.942 or 289,326 may be arranged within the tube 1 which is enlarged for this purpose. The lamp may be employed in recording sound or in the electrical transmission of pictures, the intensity of the radiations being varied in accordance with currents or potentials representing sound waves by applying potential variations between one pair of electrodes while polarizing discharge may be maintained between one of these electrodes and a third electrode or between two separate electrodes. According to the Provisional Specification, the lower end of the tube rests in a bath of mercury which acts as a seal and more than one heating element may be provided.
