Title: Improvements in and relating to furnaces for heating hollow cylinders
IPC: F27B5/00
Filed: 1922-07-05
Abstract: 201,013. Woodall, Duckham, & Jones (1920), Ltd., and Duckham, Sir A. M. July 5, 1922. Muffle furnaces; charging and discharging.-A furnace for the heat treatment, enamelling, &c. of hollow cylinders comprises an annular muffle c, into which the cylinders are raised from below. The furnace is mounted in a raised position on a framework @b, so that a truck m carrying the muffle closure k and a cylinder l can be run beneath it, whereupon rack or hydraulically-operated rams o are actuated to raise the cylinder into the muffle, a tight joint between the furnace and the closure being made by sand seals k. The muffle is heated on both sides, and the diameter of the muffle in relation to that of the cylinder is so chosen that both sides of the latter are heated equally. Gas and air are supplied through radial flues e at the top of the muffle to vertical flues g, and the heating gases pass downwards through these flues, upwards through adjacent flues h, across the top of the muffle through radial flues h<1>, and then down through outer vertical flues h<2> to a collector flue h<3> and the stack. The air for combustion is heated in an annular flue d surrounding the flues h<2>.

Title: Improvements in or relating to methods of and means for cooling solenoid windings
IPC: H01F7/16
Filed: 1924-08-05
Abstract: 220,310. Compagnie Internationale des Freins Automatique Soc. Anon. Aug. 8, 1923, [Convention date]. Electromagnets. - Solenoid windings are cooled by a liquid such as oil circulated by the plunger operated by the solenoid, the liquid circuit being completed through the winding enclosure. In one arrangement, Fig. 1, supply pipes 5, 7 leading from a reservoir 6 deliver oil to the chamber containing the coils 3. The core 1 slides with a piston fit in the lower part of the chamber, and valves 8, 9 cause a one-wav flow of the oil. When the oil is heated it continues to circulate, even though the electromagnet is not working. Other arrangements are described in which the oil is forced under pressure into the coil chamber and is returned bv the core movements, the initial inlet of oil being controlled by a small auxiliary solenoid. In one such arrangement. Fig. 2, when the auxiliary solenoid 11 is deenergized the inlet valve 10 opens and oil passes from pipe 7, valve 13, pipe 14 into the coil chamber. Upon energization of the main solenoid the core forces the oil back through valve 1S and pipes 14, 5. One arrangement has a core with piston integral therewith working in a separate cylinder.

A fluid pressure operated braking system for motor vehicles is provided with a plurality of brake actuators at least some of which are associated with lock actuators. The lock actuators each co-acts with its associated brake actuator output rod and is held in the inoperative position by application of pressure to its actuating mechanism. The system is controlled by a valve unit comprising a damping means for limiting the rate of movement of a hand lever 2 of the unit in the actuation of the lock-actuator "on-off" valve 10 such that the lock actuator is in its fully "brake locked" position before the lever 2 can move further to re-set the brake cylinders to their inoperative pressure condition. In the construction shown the damping means comprises an apertured piston 22 working in a chamber 17. The hand lever 2 works in an "h"-shaped slot (Fig. 2, not shown) and, for this purpose, is pivoted about two axes at right angles to each other.

Title: Improvements relating to the process of vulcanizing rubber and to the manufacture ofan accelerator for use therein
IPC: C08K5/00
Filed: 1920-07-06
Abstract: Substituted thio-ureas suitable for use as accelerators in vulcanizing rubber are prepared by the action of carbon bisulphide on neutral solutions of bases obtained by treating p-nitroso compounds of amines, substituted amines, phenols, &c. with hydrogen sulphide. p-Nitroso-dimethyl-aniline, for instance, may be dissolved in water, benzol, &c., and treated with hydrogen sulphide in the proportion of less than two molecular equivalents, preferably one equivalent, at any temperature below the boiling-point of the solution.  After evaporation, the product reacts directly with carbon bisulphide.  The two reactions may be simultaneous, the p-nitroso-dimethyl-aniline being dissolved in carbon bisulphide, with or without benzol, &c. and the hydrogen sulphide passed in.  Part of the hydrogen sulphide required is in this case furnished by the reaction with the carbon bisulphide. If as much hydrogen sulphide as can be absorbed is passed into this carbon-bisulphide solution, p-amido-dimethyl-aniline is formed and converted into the corresponding thio-urea.  Aniline may be added to a solution of p-nitrosodimethyl-aniline in carbon bisulphide so that all the hydrogen sulphide required is produced in the solution itself.  One, two, or three molecules of aniline may be supplied for each molecule of the nitroso compound, mixed thio-ureas being obtained.  The aniline should be added slowly to the boiling carbon bisulphide solution, unless three molecular proportions are used, when it is preferred to add the solution to the warm aniline. From 1/2 to 2 per cent of the thio-ureas obtained by evaporation may be added to the mixture to be vulcanized.  Specification 173,545 is referred to.
