Abstract: 163,708. Junkers, H. May 25, 1920, [Convention date]. Mixing-valves.-A valve fitting for mixing hot and cold water comprises a casing 4 of pressed or drawn sheet metal formed as a surface of revolution carrying two valves 2, 3. The outlet chamber of the valve 2 communicates by a pipe 8 with a pipe 19 which is connected to the top of the hot-water reservoir 14 and to a shower fitting. The outlet chamber of the valve 3 communicates by a pipe 17 with a pipe 15, 11 which terminates at the bottom of the reservoir 14. When the valve 3 is opened, cold water enters by the pipe 1 and passes by the pipes 18, 15, 11 to the bottom of the reservoir 14, displacing hot water from the top through the pipe 19 to the shower. If the valve 13 also is open, the water passes down through the pipe 19 and openings 10, 10' to the outlet 12. If the valve 2 is open, cold water passes through the pipe 8 to mix with the hot water for delivery to the shower or to the outlet 12. In a modification, Fig. 4, a hollow casing 23 is fixed to a wall and provided with inlet pipes 21, 22 for cold and hot water. The pipes carry valves 24, 25 similar two 2 and 3, but the valves discharge directly into the casing.

Title: Preparation of boron trichloride
Inventor: SMITH HUEY GENE
IPC: C01B35/06
Filed: 1959-04-27
Abstract: <PICT:0874557/III/1> Boron trichloride is prepared by reaction of an oxygenated, inorganic, boron compound having a melting point less than 1000 DEG C., and a chlorinating agent in a fluidized bed of particulate carbon heated to above the melting point of the boron compound and in the range 600-1000 DEG C., a weight ratio of boron compound to carbon of 1:15-1:50 being maintained in the bed by addition of particulate carbon and the boron trichloride being recovered from the gaseous reaction products.  A bed of particulate carbon of 20-200 mesh is fluidized in a reactor 1 by nitrogen gas from vessel 5 entering through 19 and leaving through outlet 10. Reactor 1 is heated by electric heating elements 12.  When reaction temperatures are reached the nitrogen is cut off and replaced by a stream of chlorinating agent from storage vessel 4 by closing valve 27 and opening 26, the carbon in the reactor still being maintained in a fluidized state.  A boron compound, e.g. calcium, magnesium, or sodium borate, particularly boric oxide or borax of particle size less than 1/8 inch, is added to the bed from storage vessel 2 through inlet 16 in the stoichiometric amount for reaction with the chlorinating agent.  The reaction is exothermic and heating elements 12 may be shut off after commencement of the reaction. Gaseous reaction products containing boron trichloride leave the reactor through pipe 10 the boron trichloride being isolated by solvent extraction or cooling and condensation of the gaseous stream.  The carbon utilized in the reactor is replenished from storage vessel 3 by opening valve 21 and allowing fresh carbon to enter reactor 1 in gaseous suspension in the chlorinating agent flowing in conduit 19. Removal of carbon from the reactor particularly when boron compounds other than boric oxide are employed which results in the carbon being clogged with by-product salts, is effected through outlet 14 and valve 15.  Other gases, e.g. N2, may be added to the chlorinating agent to maintain fluidized conditions in the reactor during reaction and reference is also made to the admixture of oxygen with the chlorinating agent to effect combustion of the carbon in the bed to increase the reaction temperature without need for external heating. When employing boric oxide or borax as the boron compound weight ratios of boron compound to carbon of 1:30 to 1:40 and 1:20 to 1:30 respectively are employed and preferred temperatures of 700-800 DEG C. for boric oxide and 780-850 DEG C. for borax are also specified. The chlorinating agents may be chlorine, phosgene, thionyl chloride, phosphorus trichloride or pentachloride, or carbon tetrachloride.

Title: Improvements in and relating to apparatus for controlling the movements of a gun mounted on a vehicle, for example an aircraft
IPC: F41A27/26
Filed: 1940-09-25
Abstract: 565,050. Gun mountings. BOULTON PAUL AIRCRAFT; Ltd., DOE, A., and HOLMES, R. Sept. 25, 1940, No. 14539. [Class 92 (i)] Relates to means for preventing endangering movements of guns mounted on aircraft or other vehicles and provided with a training motor 4 and an elevation ram or motor 7 fed, for example, by pipe-lines 2, 3 and 5, 6 from a pair of pumps mounted in a casing 1 and controlled by a single lever 8. According to the invention, a cut-off valve 15 is provided in the elevation circuit with a non-return valve 16 in parallel permitting flow only in the direction causing elevational movement to avoid the obstruction, and two cut-off valves 9, 10 with non-return valves 13, 14 permitting flow in opposite directions are provided in the training circuit. Further, a cam or electric conducting member 17, rotating in synchronism with the training movement and shaped to conform with the obstruction, has a follower 31 which serves under danger conditions to close the valve 15 and one or other of the valves 9, 10 whereby the corresponding non-return valves act to permit movement of the liquid only in a direction to cause movement of the guns away from the obstruction. As shown, the obstructions are represented by the shaped conducting members 18, 19 connected to slip rings 20, 21 in circuit with the solenoid coils 25, 28 of electromagnets which actuate the cut-off valves 9 and 10 respectively. The follower 31, which moves vertically on the member 17 in accordance with gun elevation, is connected through the solenoid coil 30 of the cut-off valve 15 to the circuit which includes a battery 26. It follows, therefore, that, as soon as the gun is brought into an endangering position causing the follower 31 to contact the conducting area 18, 19, movement of the gun towards the obstruction is stopped and operation of the handle 8 can only cause the motors 4, 7 to move the gun in a direction away from the obstruction. A casing for inclusion in the pipe-lines is described embodying the electromagnet, the cut-off valve 'and the non-return valve as a single unit.

Abstract: 383,636. Paper boards. RICHARDSON CO., Wyoming Avenue, Lockland, Ohio, U.S.A. May 16, 1931, No. 14568. Convention date, July 16, 1930. [Class 96.] The process for making a fibrous pulp described in Specification 341,542 is applied to the production of a fibrous pulp containing a synthetic resin. A phenol-formaldehyde &c. resin is prepared in a molten condition, the fibrous material added to it, and both materials are kneaded to disintegrate and disperse the fibres prior to the whole mass being partially broken up by the addition of water, which the fibres absorb readily, and then treated in a beater ; the temperature of the mixture is kept below that at which the resin polymerizes and becomes infusible and the adhesive and extensible condition of the resin assists in the dispersion of the fibres. In the resulting material, there is no continuous surface film of resin. Waste stock from the material so made can be utilized again by adding to the fibrous material and resin an amount of stock up to 50 per cent of the weight of the total mass thereof. The Specification as open to inspection under Sect. 91 states that the resin may be prepared from acidic anhydrides and esters of polyhydric alcohols, by condensation of aldehydes with amines, by polymerization of hydrocarbons or by condensation of ketones with themselves. This subject-matter does not appear in the Specification as accepted.
