Title: Process for the production of microporous rubber
IPC: A47F11/00
Filed: 1930-05-01
Abstract: In the process for the production of microporous rubber of the parent Specifications, the latex is thickened by the addition of salts other than soaps having monovalent cations, such as sodium chloride, or sodium salicylate.  The presence of small quantities of soap, e.g. used in the production of a concentrated latex, is not objectionable. In an example, 10 c.cm. of 15 per cent sodium chloride solution are added to 100 c.cm. of a latex concentrated as in Specification 213,886, [Class 70, Indiarubber &c.], and containing 60 per cent rubber, 15 per cent sulphur, and 2 per cent "agerite" (phenyl b naphthylamine).  The latex thickens and is spread and coagulated, e.g. by hydrochloric acid or sulphur dioxide, and is vulcanized by the process of the main patent.

Title: Improvements in or relating to the production of sulphuric acid
IPC: C01B17/765
Filed: 1936-05-13
Abstract: A gas containing sulphur dioxide, oxygen, and water vapour is subjected to catalysis to convert part of the sulphur dioxide to trioxide, which is then removed as concentrated sulphuric acid by condensation with the whole of the water vapour, the remaining gases being reheated and subjected to further catalysis.  In a modification, the water vapour is added after the first stage of catalysis.  The inlet and exit temperatures of the first converter may be 440 and 600 DEG  C. respectively, and those of the second one 380 and 450 DEG  C.  The exit gas from the first stage may be cooled slowly to the dew-point of the concentrated acid and then more quickly to 200 DEG  C.  The degree of conversion in the first stage may be 65 per cent.

Title: Improvements relating to change-speed gearing for machine-tools
IPC: B23Q5/18
Filed: 1941-10-29
Abstract: 553,707. Valves. HERBERT, Ltd., A., and LLOYD, A. H. Oct. 29, 1941, No. 13906. [Class 135] [Also in Group XXIV] In a variable-speed gearing for machine tools in which gear changing is effected by sliding gears or clutch members, the striking forks 33 are each mounted on a sleeve 34 slidable on a rod 35. Each of the sleeves 34, which are grouped together, has a toothed rack 36 meshing a gear 37 which also gears with racks fixed to a pair of hydraulic pistons 38, 39. Pressure fluid is distributed to the various pairs of cylinders 42, 43, 44, or the pairs of pistons 38, 39, by a single rotary selector valve 50, arranged with ports so that when one of the pistons, e.g., 39, is exposed to hydraulic pressure through ducts 75, 76, the other piston 38 of the pair is connected to the valve exhaust passage 79 by ducts 78. To enable the selector valve 50 to be turned to preselect a new speed it is normally cut off from the pressure liquid supplied through a duct 62 by a ball valve 60 which is held on to its seat by fluid pressure in a cylinder 71 acting on a plunger 61. Cylinder 71 is connected to the pressure duct 62 by passages 63, 64, annular space of a pilot valve 66 and duct 65. To effect a gear change a push button 68 is actuated to move the pilot valve 66 so as to open the cylinder 71 to a drain passage 72 whereupon valve 60 opens and pressure fluid passes from the duct 62 to the selector valve passages to cause operation of the preselected striking fork. The fluid pressure may be generated by a small pump working with an accumulator. Specifications 382,784, 429,741, 434,893, 441,141, 446,772, and 466,789, [all in Group XXIV], are referred to.

Abstract: 1,012,939. Bearings. GOETZEWERKE FRIEDRICH GOETZE A.G. April 6, 1964 [April 5, 1963], No. 14127/64. Heading F2A. A seal, for a roller bearing positioned between a hub 1 and an axle 2, has a resilient cylindrical portion 9 which is received in a radially inner surface of the hub 1; has spaced sealing lips 15, 17 which engage the axle 2; and has a metal reinforcing ring vulcanized therein. The lips 15, 17 and the axle 2 have a grease chamber 18 formed therebetween. The metal ring has a cylindrical portion 10, a radially-inwardly projecting annular flange 19 which is adjacent the bearing and a radially outwardly projecting annular flange 11 at the other end which abuts an end surface 12 of the hub 1. The flange 11 may be covered with resilient material which is integral with the portion 9 and an annular recess 13 may be provided in the end surface 12 of the hub 1 to prevent an inner edge 14 of an extension 8 of the hub 1 from striking the flange 11 during assembly. The lip 15 may be urged towards the axle 2 by a circular spring 16 and the lips 15, 17 may be separate from the sleeve 9. The internal diameter of the flange 19 is smaller than the external diameter of a cage 6 and the axial spacing of the flange 19 from the cage 6 is less than the axial spacing of the lip 15 from an inner race 5 of the bearing so that upon withdrawal of the hub 1, the flange 19 engages the cage 6, and the inner race 5 is prevented from damaging the lip 15.

Patent GB-768454-A (GB)
Title: A new phenothiazine complex
Inventor: ZABA JAROSLAV BOGUMIL JAN
Filed: 1954-05-17
Abstract: The invention comprises a complex of equimolecular proportions of phenothiazine and sulphur dioxide.  It may be prepared by allowing a solution of phenothiazine in sulphur dioxide to crystallize at a temperature below the transition temperature, i.e. below the temperature of coexistence of the complex, unsolvated phenothiazine, their saturated solution in liquid sulphur dioxide and gaseous sulphur dioxide.  This temperature lies between -2 DEG  and -8 DEG C.  The complex may also be prepared by contacting phenothiazine with sulphur dioxide at temperatures below the transition point preferably in the presence of small quantities of a saturated solution of phenothiazine in liquid sulphur dioxide.  Phenothiazine may be regenerated by allowing the sulphur dioxide to evaporate under reduced pressure or elevated temperature.  The regenerated phenothiazine may be produced in a very finely-divided state by a mild grinding operation and the grinding may be simplified by mixing the regenerated phenothiazine or the reaction mixture with a surface-active agent.  Non-ionic surface-active agents, such as ethylene oxide condensation products of alcohols or phenols, are particularly suitable.  In the examples: (a) crude pheno thiazine and a condensation product of sperm oil alcohols and ethylene oxide are dissolved in liquid sulphur dioxide; the sulphur dioxide is evaporated by reducing the pressure above the solution until the temperature drops to - 10 DEG  C.; a solid phenothiazine complex with sulphur dioxide crystallizes out; phenothiazine is regenerated from the complex by lowering the pressure and/or raising the temperature to atmospheric and when mixed with methylenebis - naphthalene - 2 - sulphonic acid can be ground to a powder easily dispersible in water; and (b) regenerated phenothiazine is prepared as in (a) in the absence of the ethylene oxide condensate and is then wet milled with the sodium salt of a methylene-bis-naphthalene-2-sulphonic acid to give a suspension which does not settle after 24 hours.

In a machine cooled by the evaporation of liquid e.g. a halogenated hydrocarbon in longitudinal ducts in the stator and recondensed in a cooler 26 higher than the machine, gravity circulation of the cooling medium is achieved by the slope of the cooler causing the liquid to flow in one direction. The stator endspaces 21, 22 are sealed by rings 23, 24 and a fibreglass sleeve 25 bonded into the stator bore. The condenser is connected to these end-spaces by passages 29, 30, the condensate returning through duct 36 from the lower end of the condenser. As shown, the rotor is cooled by water fed to an annular space 42 within the rotor stack through suitable bores, but in a modification (Fig. 2, not shown) the rotor receives the same coolant as the stator and from the same condenser. The stator terminals may be immersed in the liquid.
