Title: Improvements in or relating to carburettors
IPC: F02M17/22
Filed: 1952-10-22
Abstract: 727,333. Surface carburetters. WOOD, A. R., WOOD N. R., and FANNING, F. E. Oct. 22, 1952 [Oct. 22, 1951], No. 26499/52. Class 7(3). A carburetter comprises an aeration chamber, means for controlling the level of liquid fuel in the aeration chamber, a first series of aeration tubes supported on a central column within the aeration chamber the tubes leading from the outside of the aeration chamber and each terminating in an arcuate portion provided with a series of small holes adapted to lie on the floor of the aeration chamber, a second series of aeration tubes each having a series of small holes in the lower end and suspended about and communicating with the interior of the central column which is connected to the outside of the aeration chamber and, third, air inlet means positioned in the upper part of the aeration chamber between the liquid fuel level and the outlet. As shown fuel is maintained at the level 29 in the lower part of a chamber 19 by means of two float controlled valves 18, 63. Air is drawn in by the engine suction through an air cleaner not shown into tubes 66-70 which terminate in perforated arcuate portions below the level of the fuel. This air produces a foam in the lower part of the chamber. Additional air from the air cleaner enters through a tube 105 and passes into tubes 92-96 which comprise perforations 99 slightly larger than those in the other tubes. These perforations face approximately the centre of the chamber and are arranged so that jets of air issuing from adjacent holes cross one another. Further additional air enters through calibrated holes 109. In its path to the engine the fuel air mixture passes through holes 118 covered by a filter gauze 115 into a chamber 33. At higher speeds a valve 126 opens under the effect of suction and admits yet another supply of additional air. On leaving the chamber 33 the mixture passes a non-return valve 130 and a plate 136A having ports not shown. It then leaves by way of a tube 139 and connection 140 having connecting faces 141, 142 to which the engine inlet manifold is attached. A butterfly valve is located within the connection 140. A back fire valve relief valve (not shown) is fitted to the chamber 33. A ring 54 is carried by lugs 48-52 (Fig. 5) and a central pillar 55 is secured by lugs 56.

Title: A method of and apparatus for treating polyvinyl alcohol film
IPC: C09J129/04
Filed: 1959-08-04
Abstract: Polyvinyl alcohol film is treated to prevent fragility as the result of heat treatment, by humidity conditioning it after heat treatment and finally smoothing it.  The film may be heated uniformly on both sides to a temperature between 150 DEG C. and its melting point, then humidity conditioned at 30 DEG -90 DEG C. and 70-100% relative humidity and then smoothed at 35 DEG -80 DEG C., the temperature, relative humidity and period of humidity conditioning being so selected relatively to one-another that the film after humidity conditioning has a moisture content of 8-10%.  The film may be heat treated by causing it to travel in a sinuous path over and in contact with one or more pairs of rolls maintained at 150 DEG -210 DEG C. It may be heat-treated while it is subjected to longitudinal and lateral tension, and the period of the heat treatment may be 10-120 seconds. The period of residence of the heat-treated film in the humidifying chamber may be about 1-5 minutes.  The succeeding smoothing step is effected by causing the film to travel in a sinuous path over two or more pairs of smoothing rolls, the temperature of which is maintained at 35 DEG -80 DEG C., and wrinkles formed in the film during the humidifying step are thereby removed and the water content of the film reduced to about 4-5%.  The water content of the film is then approximately in equilibrium with respect to the atmosphere.

Abstract: 806,602. Filling projectiles. SOC. TECHNIQUE DE RECHERCHES INDUSTRIELLES ET MECANIQUES. Sept. 16, 1955, No. 26650/55. Class 9(2) After filling a projectile by pouring a molten explosive containing finely-divided solid particles of a more powerful, denser explosive in suspension, the projectile and a superjacent and communicating reserve of explosive feed are heated to a temperature at least equal to the melting point of the molten explosive, but lower than that of the solid explosive, for a period long enough to effect sedimentation of the finely divided solid. Funnel 2 having extension 3, which may have a volume at least equal to that of the projectile cavity, is assembled into the base of hollow charge projectile 1 and cotton, or wool, muff 5 is placed about the filling hole. Sleeves of light alloy, bronze, or steel may be used in place of these muffs, the object of which is to reduce cooling in the constricted portion of the filling hole and prevent " pipe " formation. The projectile and funnel assembly is heated to 95‹C., and a mixture of hexogen and trotyl at 95‹C. is poured into the funnel. The filled assembly is heated for 10 mins.-1 hr. at 95‹C. to allow sedimentation of hexogen on to the hollow charge liner 10. The assembly is cooled. the funnel and reserve feed is separated from the projectile, and explosive is reamered from the filling hole by cutting edges 8 (Fig. 2) on four guiding and centring wings 7 on rotatable rod 6 to a level 9 up to one-tenth of the calibre from the apex of liner 10. The reamered cavity is refilled, as above by replacing the funnel on the projectile with the reserve explosive feed, and heating the filled assembly at a temperature at least equal to the melting point of the molten explosive, but lower than that of the solid explosive for a period sufficient to effect sedimentation of the solid explosive. The primer cavity is finally reamered out as in Fig. 2. Pentolite and hexogen/, trotyl/aluminium are also referred to. Specification 789,761 is referred to.
