Patent GB-632588-A (GB)
Title: Improvements in or relating to the manufacture of rubber latex products
Filed: 1947-02-15
Abstract: A shaped mass of aqueous dispersion of natural or synthetic rubber (which may be contained in a mould or disposed on a dipping former) is placed in a chamber, and the air or part of the air in the chamber is displaced by steam at atmospheric pressure.  If the dispersion vulcanizes at a temperature below 100 DEG  C., only part of the air in the chamber is displaced, there being formed a mixture of steam and air having a dewpoint at the said temperature.  If the dispersion vulcanizes at 100 DEG  C., all the air is displaced. In either case the supply of steam is adjusted to maintain the dispersion at the vulcanizing temperature.  The dispersion may be a frothed dispersion of the kind described in Specifications 332,525 and 332,526, [both in Class 70], which may gel at 50 - 80 DEG  C. and vulcanize at 100 DEG C., in which case the dispersion is first gelled, by displacing only part of the air to produce a partial pressure of steam, and then vulcanized by displacing all the air by steam; or the frothed dispersion may gel in the cold, in which case the first step is omitted.  The apparatus described in Specification 632,088 may be used, this apparatus comprising a base and a movable cover member which together form a chamber. Specification 487,350 also is referred to.

Abstract: 994,256. Hydrodynamic couplings. C. SCHULER-VOITH, M. VOITH, and H. RUPF. Feb. 4, 1964, No. 4638/64. Heading F2C. A hydrodynamic coupling comprises an impeller 3 having a chamber 6 rotating therewith having inlet valves 12 located radially inwardly of the inner periphery 9 of the impeller, and having discharge orifices 8 at about the mean radius of the impeller blades. The inlet valves 12 are rotary valves controlled by centrifugal weights so that they are open below a predetermined pump speed and closed above this speed. Below the predetermined speed, and with medium or high clutch slip liquid entering the space 10 beneath the inner periphery 9 of the impeller passes into the chamber 6 at a greater rate than it is discharged through the orifices 8 to partially empty the coupling and reduce its transmission capacity. The chamber 6 is provided with radial blades 6a, and the impeller may be formed with projections or plates inwardly of the orifices 8 to reduce the pressure at the outlet of these orifices to facilitate discharge from the chamber 6. One or more guide plates may be associated with a corresponding number of inlet valves 12 to direct liquid thereto when the toroidal flow in the coupling is reversed in order to act as a brake with reduced filling. The inlet valves 12 may also be associated with flow deflection means to guide liquid thereto for either direction of peripheral rotation in order to permit the coupling to be used for either direction of rotation. Venting ducts may be provided proceeding from a central position of the chamber 6 to near the inner periphery of the impeller to permit an interchange of air between the coupling and the chamber 6.

Abstract: 266,734. Soc. Anon. du Carburateur Viel. Feb. 26, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Spray carburettors. - In carburettors having one or more main sprayers of the submerged type, and a slow-speed sprayer fed directly from the float chamber, means are provided to ensure a continuous and accurate supply of fuel from the slow-running condition until the main sprayer is fully in action. The float chamber C supplies a slow speed sprayer T, and a main sprayer A at the junction of conduits D, D<1>. The sprayer T discharges into a pipe E provided with a cock K and delivering mixture into the induction pipe above the throttle valve F of the thin metal disc type. A conduit 0 extends into the conduit D<1> to the normal fuel level and discharges into a conduit X provided with a calibrated aperture V and communicating with the induction pipe below the throttle valve F through an orifice S. This orifice comes into action as soon as the throttle is opened and remains in action, adding a calibrated amount of fuel, until the main sprayer A is delivering into the diffuser R. In place of a single orifice, two orifice!; S, S<1>, Fig. 4<a>, on opposite sides of the throttle spindle may be employed, in which case it is immaterial in which direction the throttle is opened. The orifice which remains below the throttle will serve as an air inlet to the conduit X. This modification permits of the throttle lever being located in the most convenient position, and of the carburettor being adapted for various engines. The Specification describes, with the aid of drawings, known devices for attempting to eliminate the gap between slow and normal running conditions.
