Title: Improvements in or relating to the vulcanisation of rubber articles
Inventor: DRAKEFORD GEORGE EDWARD
IPC: B29B15/02
Filed: 1956-05-03
Abstract: <PICT:0855345/IV(a)/1> <PICT:0855345/IV(a)/2> <PICT:0855345/IV(a)/3> <PICT:0855345/IV(a)/4> In bonding an unvulcanized natural rubber member to an unvulcanized natural rubber article, the areas of the surfaces to be adhered together are limited by interposing an unvulcanized Butyl rubber element between surface areas not to be bonded, whilst vulcanizing the assembly, and subsequently removing the vulcanized Butyl rubber element.  In the manufacture of a dual chamber tube for a pneumatic tyre and comprising inner and outer tubes joined together at their inner peripheries to form a common base, annular strips 2, Fig. 1, of unvulcanized Butyl rubber are placed circumferentially around the exterior of an unvulcanized natural rubber inner tube 1 at the desired lateral limits of the common base.  Two annular fillets 3 of unvulcanized natural rubber are then arranged so that a part of each covers a strip 2 and the other part is adhered to the tube 1.  The latter is then inflated and the assembly is partially cured in a mould of toroidal shape so that the part of each fillet 3 covering a strip 2 is formed into an annular portion 6, Fig. IV, whilst the other part of each fillet is incorporated into the wall of the tube 1.  The Butyl rubber strips 2 are not adhered to the tube 1 by the partially curing process and are now removed.  The base portion of the tube 1 between the portions 6 is then buffed, coated with rubber solution and secured by vulcanization to a natural rubber outer tube 7, Fig. V. Alternatively the Butyl rubber strips 2 are located in unvulcanized natural rubber fillets 4, Fig. VI, of substantially U-shaped cross section, and two unvulcanized natural rubber base strips 5 of tapering cross-section are placed around the inner tube 1 between the fillets 2 as shown.  The manufacture of the dual chamber tube is then completed in the same manner as in the process described with reference to Figs. I, IV, and V. Base strips may also be used in the construction illustrated in the latter Figures, but are not essential.

Abstract: 164,727. Ingersoll-Rand Co., (Assignees of Bancel, P..4.). June 5, 1920, [Convention date]. Surface condensers; bulk evaporators. - To increase the efficiency of a heat exchanger in which steam is condensed, the flow of vapour with its admixed air is retarded at points between the cold surfaces. In the example shown in Figs. 2 and 3, a casing A receives the residual vapour and air from a condenser, on their way to the air port C. Water tubes D, more closely spaced near the outlet, are provided with intermeshing fins O which retard the flow of gases between the tubes, thereby reducing the relative speeds at points between and at the cooling surfaces. The retarding plates may be of metal and wood-their conductivity being of relatively small importance. In the Specification as open to inspection under Sect. 91 (3) (a), a modification shown in Fig. 5 (Cancelled) is provided with retarding devices in the form of continuous parallel plates b extending between tubes Z, the plates being more closely spaced near the outlet. Further, in the evaporator shown in Fig, 8 (Cancelled), steam admitted at Q passes among the vertical evaporator tubes R to the space S bounded by baffles T in which plates d and tubes c are arranged substantially as shown in Fig. 5 (Cancelled) or separate gilled tubes similar to those shown in Figs. 2 and 3. This subject-matter does not appear in the Specification as accepted.

IPC: C06B25/32
Filed: 1931-05-13
Abstract: Crude pentaerythritol tetranitrate, preferably after a preliminary wash with dilute aqueous alkali carbonate is treated with a solvent that is substantially immiscible with water, volatile in steam, stable in the presence of boiling dilute alkaline solutions such as dilute sodium carbonate solution, inert to pentaerythritol tetranitrate under the conditions of working and preferably with a boiling point higher than water such as nitrobenzene, or n-amyl alcohol, the crude pentaerythritol tetranitrate being isolated separated from the solution of the free acid, and insoluble impurities have been removed.  It is then subjected to steam distillation in the presence of water and a mild alkali such as dilute sodium carbonate or ammonia.  The ammonia may be introduced in the current of steam and the solvent which is distilled off is recovered and used again.  In an example moist crude pentaerythritol tetranitrate is dissolved in nitrobenzene, filtered diluted with an excess of dilute sodium carbonate so that the liquor is alkaline to litmus paper and steam distilled.  The crystals which separate out are washed with water and dried.

Abstract: 349,278. Plug cocks ; accessories. UNITED STATES METALLIC PACKING CO., Ltd., Soho Works, Allerton Road, Bradford, Yorkshire. May 9, 1930, No. 14352. Convention date, Nov. 8, 1929. [Class 135.] Wedging or jamming.-In a rotary plug cock means are provided, associated with the operating handle p, Figs. 1 and 2, for wedging the plug b into its seating in the closed and fully open positions and releasing the plug in the initial movement of the handle p from either of these positions. The said means comprise essentially a ring d rotatable with the plug and slidable thereon by co-operation of cam projections f on the ring engaging recesses g and adjoining inclined surfaces p<1>, p<2> on the boss of the handle p. In operating the cock from a terminal position, indicated in Fig. 2, the inclined parts p<1> of the handle p first leave the top of the cam projections f which then move up into the recesses g under the action of the spring i, the plug being now unwedged ; on further movement of the handle coaction between the cams f and recesses g rotates the ring d, and with it the plug b. On arrival at the other terminal position, the ring d and plug b are arrested by coaction between a projection k and a stop k<2> on the casing, the further movement of the lever causing the recesses g to ride over and force down the cam projections f whereupon the ring d moves down to a lower abutment flange, and the inclined part p<2> mounts the projections f and forces upwards the handle p and plug b to wedge the same in its seating. In the unwedged movement the ring d abuts against a ring e having ball bearings. The lower end of the plug bears upon a central ball bearing which can be jammed by a screw for repairs to the upper wedging parts.
