Title: An improved automatic machine for fitting and simultaneously vulcanising rubber soles on boots or shoes
IPC: B29C35/00
Filed: 1946-08-02
Abstract: 617,211. Machines for moulding rubber soles on boots and shoes. CAPDEVILLA, G. M. Aug. 2, 1946, No. 23166. Convention date, March 30. [Class 87 (ii)] A bridge 11 pivoted at 12 supports from its head 9 a last 54. The mould consists of two side jaws 3 and a heated base 41. The jaws 3 slide horizontally within guides 4, 41, which are secured to the bridge 11, and the base 41 slides vertically within the guides 4, 41. When the bridge 11 rocks to the left, Fig. 1, the jaws 3 are urged together by means of pivoted struts 5, Fig. 3, disposed between the jaws 3 and the machine frame. The base 41 then rises to complete the moulding. When vulcanisation is complete, the bridge 11 rocks to the right, Fig. 1, the jaws 3 open and the base 41 then descends. This sequence of operations is performed automatically by means of an axially displaceable screw-threaded shaft 14 pivotally connected to the bridge 11, the shaft 14 engaging in an internally screw-threaded gear member 16 driven by a reversible motor 19. Fig. 3. On starting the motor 19 the shaft 14 is axially displaced to the left, Fig. 1, thus rocking the bridge 11, until clutch members 64, 66, engage, when the shaft begins to rotate without axial displacement. This rotation is transmitted to a gear-box 31 via shafts 24, 26, 28, thus operating a hydraulic cylinder 33 which in turn causes a piston 39 in the ram chamber 35 to rise together with the base 41. A timing device (not shown) keeps the base 41 stationary for a period, after which the motor 19 is automatically started in the reverse direction when this sequence of operations is reversed. The machine is adapted to mould two soles simultaneously, the line A-A<1> in Figs. 2, 3, denoting the vertical plane of symmetry of the machine.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J29/87
Filed: 1935-08-19
Abstract: 461,334. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 19, 1935, No. 23253. Convention date, Oct. 29, 1934. [Class 39 (i)] In an electric discharge tube the wall of which is wholly or partly of glass, at least part of the glass wall is divided into a plurality of layers.and the pressures in the cavities between the layers are constant and form, from the exterior to the interior of the tube, a constantly increasing or decreasing series. The wall is thus enabled to withstand internal or external pressure without excessive bulk or curvature. The layers may have different thicknesses and the same or different radii of curvature, including plane and inwardly curving surfaces. The curvature and thickness may vary throughout the same layer, especially in the edge zone to obtain stability. One or more layers may be coated with a layer of material affording protection against splintering such as gelatine, and highly refractive substances such as carbon disulphide or Canada balsam may be introduced into one of the cavities to provide an optical system. In one example, Fig. 1, the wall of a discharge tube has five layers 5 sealed to the stem 3, the inner space being evacuated and the pressures in the intermediate spaces 7 forming an increasing series. In a cathode-ray tube, Fig. 2, only the end of the tube is formed of layers 9, so that the fluorescent layer may be applied to a practically plane surface. The remaining frusto-conical portion 11 of the envelope may be made of ferrochromium, ceramic material or thick glass, and when of conductive material or provided with a conductive coating may be connected to earth or fixed potential through capacitative or inductive means. The end layers 9 are sealed to extensions 13 on a thickened portion 12 of the wall. Exhaust tubes are provided for each cavity, which may be of glass but are preferably of metal and contain solder which when melted runs into kinks or cavities in the tubes to seal them after pumping. The invention is applicable also to photoelectric cells, lamps and X-ray tubes. To avoid subjecting the layers to excessive pressures during pumping, all the cavities may be connected to a common pump, through capillary tubes whose resistances are adjusted so that each cavity attains its correct pressure during the exhaust period. One or more substances having a measurable vapour pressure may be introduced into one of the cavities. Specification 312,507, [Class 39 (i)], is referred to.

Abstract: 1,140,922. Continuous production of polyesters. MELLE-BEZONS. 18 May, 1967 [10 June, 1966], No. 23265/67. Heading C3R. [Also in Division B1] In a process for the continuous production of polyesters from polycarboxylic acids or anhydrides thereof and polyhydroxy compounds the reactants are passed in countercurrent to vapours of an azeotropic water entrainer bubbling through the mixture. Suitable water-containers are hydrocarbons, e.g. benzene, toluene, n-hexane, cyclohexane, methylcyclohexane and n-heptane. The reactants may be mixed under an inert atmosphere at 50-200 C. then reacted in a series of reactors in. cascade formation, or in a plate column, at 180-260 C., the water entraining vapours being introduced at or near the bottom of the last reaction zone, the waterentrainer having been degassed by boiling before use. The Figure shows a preferred arrangement in which the reaction takes place in a cascade of three reactors (15, 16, 17) having heaters (19, 20, 21); water-entrainer is led via column 31 in which it is degassed into a boiler 32, whence the vapour proceeds in part through column 31 to condenser 35 and in part through overheater 37 into the reactors 17, 16 and 15 in sequence; the vapours from the first reactor (15) are led into a distillation column 8 in which entrained reactants are condensed and returned to the reactor 15, while the head vapours are condensed in a condenser 10, the water being discarded and the water entrainer being in part returned to the head of the column 8 and in part rectified and used again; the reactants are mixed in the heated vessel 1 and led into the column 8, in which they are degassed and from which they pass with the condensed material to the first reactor (15). In examples, polyesters are prepared in such apparatus from propylene glycol or propylene glycol/diethylene glycol or diethylene glycol or ethylene glycol, and maleic anhydride with phthalic anhydride or tetrahydrophthalic anhydride or tetrachlorophthalic anhydride or adipic anhydride, i.p.o. hydroquinone or p-tbutylcatechol as stabilizer using cyclohexane, benzene or n-hexane as the water-entrainer at 200-250 C. The products may be mixed with unsaturated monomers.

Title: Improved method of and means for obtaining rubber in granular form from dispersions such as latex, or from solutions
IPC: C08C1/12
Filed: 1931-08-21
Abstract: Rubber in powdered form is obtained from solutions or dispersions, e.g. latex, by dividing the liquid into drops, catching the drops apart from each other on a drying surface, and removing the dried non-cohering particles from the surface.  The drops may be obtained by any known dropping or spraying device, but are preferably obtained by discharging the liquid in a thin stream which breaks up into separate drops at a short distance from the nozzle.  The drying may be effected by heating either side of the collecting surface or by passing a current of hot gas along it; it may be assisted by the use of reduced pressure by flattening the drops on the surface (e.g. by means of rollers), or by concentrating the drops as they fall to the surface.  The separate collection of the drops may be effected by moving either the dropping device or the collecting surface or both. For example the drops may be collected on the interior or exterior surface of a rotating drum from which the dried rubber is removed by a scraper.  Alternatively the collecting surface may be an endless belt, a rotating disc, or a series of loose bodies carried on a conveyer.
