Title: An improved tool for removing the outer jackets of pneumatic tyres of the clincher type from their rims
IPC: B60C25/02
Filed: 1922-10-16
Abstract: 198,286. Michelin et Cie, and Michelin, E. E. Oct. 16, 1922. Tyres, elastic, and tyre covers, tools for removing.-A tool comprises casings 5, 6 each rotatably mounted on a spindle 4 through bearings 4<1>, the casing 5 containing a lever 7, and the casing 6 a lever 16. The lever 7 terminates in prongs 7<1>, each prong having a heel 7<2> adapted to pull off the tyre bead remote from the tool, and the lever 16 has a hooked end. Claws 1, 2 adapted to engage one side of the rim are coupled together by a rod 3, and are fast with the spindle 4, auxiliary levers 24, 25 being attached by chains 26, 27 to the casing 6. A removable crank handle 21 operates the levers 7, 16 through screws S, 17. To remove a cover the lever 16 is partially moved out, hooked over the rim and withdrawn, causing the claws 1, 2 to hook over the rim. The lever 16 is then advanced under the near bead of the tyre and the inner tube, the casings 5, 6 being then pivoted about the spindle 4 to bring the parts into the position shown in Fig. 9. The support 5 is further turned so that the lever 7 can be advanced until the heels 7<2> come beneath the bead of the jacket remote from the tool and levers 24, 25 inserted, lever 16 being withdrawn. The lever 7 is again positioned horizontally and advanced until the edge of the head rests on the lever against the heel 7<2>. The lever 7 is now withdrawn and rocked against the rim to remove the jacket from the rim.

Title: Improvements in or relating to methods of, and apparatus for, treating the end facesof longitudinally extending articles
IPC: H01G13/00
Filed: 1961-08-02
Abstract: 952,907. Capacitors. SIEMENS & HALSKE A.G. Aug. 2, 1961 [Aug. 3, 1960], No. 28093/61. Heading H1M. [Also in Division B3] The end faces of longitudinally extending articles, e.g. roll capacitors, are treated, e.g., by in succession between a pair of guide tapes applying electrically conductive material thereto intermediately of which the articles are successively arranged with axes perpendicular to the tape axis; the tapes being drawn together in the spaces separating the articles so that the faces of the articles other than the end faces are wholly overlain by the tapes and the treatment is confined to the end faces. In the manufacture of rolled capacitors, (Fig. 4), units 14 are stored in hopper 15 and pushed sequentially by magnetically or hydraulically reciprocated punch 16 between laterally extending tensioned guide tapes 23 from storage rolls 6, 7 into a constricted guide at the centre of a rotatory housing carrying storage rolls 10, 11 for binding tapes 4, 5 so that the units are formed into a continuous chain (Figs. 1, 2) in which tapes 2, 3 are bound together in the intervals between units 1, 1<SP>1</SP>, 1<SP>11</SP> &c. by tapes 4, 5 which run obliquely over the successive units, so that the circumferential surfaces of the latter are masked. Punch 16 has a head of rhomboidal cross-section offsetting the binding tapes 4, 5 from the guide tapes 2, 3 during the winding operation (Fig. 5). After the binding operation, a press member 17 synchronized therewith impinges on plural units of the chain to progressively and partially flatten them, and successive synchronized press members 18, 19 complete the flattening process and are critically spaced to impinge on successive single units The chain is rolled on a storage reel 20 driven through a slip clutch (not shown) and adjacent turns may be separated by a distance-piece 21. The roll is removed and the unmasked ends of the units are metal-coated by spraying or electrodeposition for connection, after which leads may be soldered thereto. Subsequently the chain may be unwound from roll 20 over guides 22, 23 positioned oppositely to louvres 24, 25 severing the binding tapes so that guide tapes 2, 3 may be stripped at 28, 29 and rolled on reels 26, 27 to release the individual capacitor units (Fig. 6). The apparatus is generally applicable to the processing of longitudinally extending articles capable of assembly in chains with guide and binding tapes, and strings or tubes may be used for binding.

Title: Gas absorbing fabric and method for producing same
IPC: D06M11/79
Filed: 1930-09-23
Abstract: A gas-absorbing fabric is made by impregnating a fabric such as sacking with one or more activated inorganic gels, for example silica or aluminium oxide gel.  The gel or corresponding sol may be applied to one or both sides of the fabric by pressing or rolling or it may be formed on the fabric by precipitation.  In examples the precipitation of silica gel by impregnation first with sodium silicate solution and subsequently with ferric chloride solution or concentrated hydrochloric acid, followed by washing and drying, and the formation of aluminium oxide gel by impregnation with ammonia gas or solution followed by soaking in alum, are described.  Loading or finishing materials such as glazing or stiffening are removed from the fabric before impregnation.  The gel may be activated by heating, preferably in an inert, i.e. oxygen-free, atmosphere, for example in nitrogen or in vacuo.ALSO:A gas-absorbing fabric is made by impregnating a fabric such as sacking with one or more activated inorganic gels, for example silica or aluminium oxide gel.

[Class 40 (iv)] [Also in Group V] A cone for a loud-speaker or the like having integral areas of modified thickness or concentration of material for the purpose of modifying the acoustic properties of the cone is made by moulding a viscous material, such as a solution or suspension of cellulose, in a mould having complementary conical surfaces modified over relatively small areas to produce the desired uneven distribution of material. As shown in Fig. 1, the mould comprises a member 14 with aconical surface and amember 15 with a conical surface modified by recesses 27, 28, the members 14, 15 being connected by fastening means 16. The member 14 has an extension 13 mounted in bearings 11, 12 and carrying a pinion 24 driven from a variable-speed electric motor 26. The viscous material is fed from a hopper 19 through a valve 20 and a passage 17 in the extension 13 to the space between the conical surfaces of the members 14, 15. The escape of air during the moulding operation is controlled by a pet-cock 23. The diaphragm a which has rings d, e and an annular flange b of greater thickness may be produced by slidable members of which the upper member has annular recesses and passages for the escape of air during the moulding operation. The moulding member may be modified so that the cone is formed with two or more radial ridges in the form of sectors of small angle.
