Filed: 1919-05-30
Abstract: 136,763. Eagle Engineering Co., and Bradley, F. C. May 30, 1919. Tipping-wagons. - In a wagon adapted to tip to either side, the tipping operation is controlled from a longitudinal shaft 12 which simultaneously rotates two screwthreaded transverse rods 16, one at each end of the wagon, carrying slidable nuts 17 connected by pivoted links 19 to two alternative points on the wagon, the bottom of the wagon being provided with a double-faced catch 22 adapted to cause the wagon to tip by engaging rollers 8 on which the wagon body runs. The interchangeable connexion of the upper ends of the links 19 to the wagon body is effected by pins 20, 20<a> carried by chains 21. In operation, if it is desired to tip the wagon say, to the left the nuts 17 are brought simultaneously towards the right hand end of the rods 16, and the links 19 are connected to the right hand pins 20. The rods 16 are then rotated to cause the nuts 17 to travel to the left, and the wagon body is consequently moved to the left, also running on the rollers 8, until the catch 22 engages the left-hand rollers, when further rotation of the rods 16 cause the links 19 to assume a more nearly vertical position, thus tilting the wagon body. The simultaneous operations of the two screw-threaded rods 16 is preferably effected by the engagement of two bevel-wheels 14 on the shaft 12 with bevel-wheels 15 on the rods 16.

Patent GB-630724-A (GB)
Title: Improvements in and relating to the resolution of azeotropic mixtures of chlorosilanes
IPC: C07F7/20
Filed: 1947-05-22
Abstract: The azeotrope of trimethylchlorosilane and tetrachlorosilane is resolved by treating it with zinc fluoride; this converts trimethylchlorosilane into trimethylfluorosilane which is then separated by distillation.  Part of the trimethylchlorosilane is not converted during the reaction with zinc fluoride, but a further treatment improves the efficiency of the method.  In an example, dry zinc fluoride (93.2 grm.) was added with vigorous stirring to 559 grm. of azeotrope in a flask equipped with a reflux condenser and a trap cooled by a mixture of ice and acetone.  After the initial rapid evolution of gas, the mixture was heated until all the liquid in the flask had been distilled through the condenser into the trap.  The liquid from the trap was then fractionated at atmospheric pressure. Trimethylfluorosilane distilled over at about 17 DEG  C., followed by azeotrope at about 54 DEG  C., and finally, tetrachlorosilane. Approximately 35 per cent of the original azeotrope remained unresolved.  Specifications 575,667, 575,668, 591,857, [all in Group IV], and 591,860 are referred to.ALSO:Methylchlorosilanes, such as trimethylchlorosilane, dimethyldichlorosilane and trimethylchlorosilane, are converted to the corresponding fluorosilanes by treatment with zinc fluoride.  Dry zinc fluoride (1 molecular proportion) is added to the methylchlorosilane (2 molecular proportions) in a flask equipped with a water-cooled, reflux condenser and a trap cooled with a mixture of ice and acetone.  After the initial rapid evolution of gas, the mixture is heated to complete the reaction. The contents of the trap are then fractionated to obtain the fluorosilane.  The reaction may be used to resolve the azeotropic mixture of trimethylchlorosilane and tetrachlorosilane. Zinc fluoride is added to the azeotropic mixture, and the reaction product is then fractionated to separate trimethylfluorosilane from unconverted tetrachlorosilane.  Specifications 575,667, 575,668, 591,857 and 591,860, [Group III], are referred to.

The concentration of electrolyte solution in a fuel battery plant is maintained by adding concentrated electrolyte, and discarding a sufficient quantity of effluent solution to maintain the volume and concentration of the liquid. Preferably a fuel is contained in an aqueous solution of electrolyte which is fed through the battery during a working period and is then recharged with a mixture of fuel and concentrated electrolyte, possibly from a removable capsule, after discarding a quantity of electrolyte equivalent to the water formed from the fuel. A fuel battery plant includes at least one fuel cell, two tanks, means for feeding a liquid comprising a solution of fuel and electrolyte from one (supply) tank to the other (effluent) tank during a working period, and, to render the liquid suitable for use in a further working period, means for discarding an amount of liquid corresponding to the water formed in oxidizing the fuel, and means for adding to the liquid a charge comprising enough fuel to replace that used plus enough concentrated electrolyte to replace that discarded in the liquid. The plant preferably includes also means for receiving a removable capsule containing the charge of fuel and concentrated electrolyte. In one modification each tank is arranged to serve alternately as the supply tank and the effluent tank and means are provided for delivering liquid from each in turn through the cell to the other. In the preferred form of this embodiment a reversing valve to reverse the connections between cell and tanks is included so that the liquid always flows through the cell in the same direction and the fresh charge is added to the empty tank whilst the excess liquid overflows from the full tank. In another modification the liquid (hydrazine/aqueous KOH) is fed by gravity from header tank 41 into battery 40 and thence to effluent tank. When the operating period has ended pump 43 returns the liquid through filter 44 to the header tank.

The windings fit the cylindrical surface and are laterally extended parallel to the horizontal longitudinal, axis 7 withcurved overhang portions 9; in. symmetrical disposition relative to axis 7 and the normal 10 thereto perpendicular to the generated field B. A cylindrical coolant guide 11 of, e.g. plastic mat or plastic coatedmetal gauge separates cylinder 5 from inner layers 2, 4 of multiple superconductive conductors of, e.g. Nb-Ti or Nb-Zn embedded in strip conductors of Cu or Al, insulated, e.g. by winding with insulant strip. A further coolant guide 12 surrounding the winding layers is wrapped with prestressed binding. 13 of, e.g. GRP strip and superimposed with a further coolant guide 14 surrounded by winding layers 1, 4, and another coolant guide 15; all wrapped with a further prestressed binding 16. Locating members 17 with radial coolant channels 18 registering with apertures of the coolant guides 12, 14, 19 are inserted between the lateral portions of winding layers 1, 3 and 2, 4, and spacers 20 with radial coolant channels are placed between the innermost turns of individual layers 1 to 4. Thus liquid He coolant may circulate through channels 18 into guides 11, 12, 14, 15 to infiltrate the coil assembly axially and tangentially, while vapour bubbles formed therein may escape easily by natural ascent. The individual windings are consolidated with synthetic resin and connected in series for energization, and the resultant electromagnetic forces are restrained by the support cylinder 5, the locating and spacing members, and the prestressed bindings. The latter may be reinforced by I-section axially aligned rings. The helium container of the crystal (not shown) is bounded by cylinders 5, 6 and provided with inner cylinder 31 surrounding a space 30 at room temperature; the region between cylinders 5, 31 being exhausted and' a further exhausted jacket surrounding outer cylinder 6. Nitrogen cooled radiation shields and heat insulant plastic foils may be interposed in the vacuum jackets and the electrodes and plasma channel of a MHD generator may be disposed in axial space 30. The device may also be used for beam deflection in a particle accelerator or as a superconductive stator for an electrical machine. Plural winding shells and layers may be used, and it is shown that an homogeneous field is produced withincylinder 5 (Fig. 3, not shown). Cooling efficiency is independent of the geometrical position of the assembly. Bindings are replaceable by retaining tubes containing coolant guides, and the support cylinder may be elliptical or tapered.
