Filed: 1923-11-21
Abstract: 207,808. Westinghouse Lamp Co., (Assignees of Rentschler, H. C.). Nov. 29, 1922, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-A conducting path is provided between the interior and exterior surfaces of the spherical portion of the envelope of a tube of the Coolidge type so as to prevent accumulation of electrons on the interior surface. In the R÷ntgen-ray tube shown, conducting members 11 extend through the spherical portion adjacent to the cathode 8. In another arrangement conducting films, consisting for example of aluminium enamel, or of tin or other metallic foil, are formed on the interior and exterior surfaces of the spherical portion, and either connected together by one or more wires sealed through the glass, or connected with the cathode. In a further arrangement the spherical portion of the tube is made of glass or other transparent material which is more conductive than the material of the extensions carrying the electrodes. The tubes are made longer for a given applied voltage to provide the necessary insulation between the electrodes. Specification 29143/09 is referred to.

Patent GB-396780-A (GB)
Title: Improvements in the preparation of catalytic materials and of carriers therefor
IPC: B01J21/16
Filed: 1931-10-31
Abstract: Siliceous material suitable as a catalyst or a carrier is obtained by treating, in small lump or granular form, naturally occurring indurated (either naturally or by calcination) silicates of alumina, e.g. aluminous fireclays with mineral acids to extract any desired propor-tion of the basic constituents.  The residue may be calcined, e.g. at 600-700 DEG  C., after the acid treatment. In the case of silicates containing titanium, the extraction may be effected without removal of the titanium content, which may act as a catalyst or assist other catalysts deposited thereon.  By selection of silicates containing carbonaceous material, a residue of increased porosity is obtained.  According to an example, an indurated fireclay is treated with sulphuric acid, calcined at 600-700 DEG  C., moistened with a solution of aluminium nitrate and calcined at 500 DEG  C. to deposit an active alumina within the pores of the material.  Reference has been directed by the Comptroller to Specifications 319,205, [Class 1 (i), Chemical processes &c.], 354,357 and 369,283.

Abstract: 1,119,971. Reverse osmosis desalination apparatus. WATERDRINK, Inc. 19 July, 1965 [29 July, 1964; 22 Oct., 1964; 1 April, 1965], No. 30553/65. Heading B1X. Apparatus in which solutes may be removed from solution by reverse osmosis comprises an osmotic divider mounted on the outer side of an endless apertured support, the support and divider being mounted for unified rotation in a vessel, feed solution being fed to the unsupported side of the divider while the support and divider are rotated at such a rate that a centripetal force greater than gravity is applied away from the membrane on the input side so that the build-up of excessive concentrations of solute adjacent to the membrane on the input side is prevented. Thus, vessel 18 comprises dividers 58, 62 supported upon apertured concentric cylinders 60, 64 respectively, the whole being rotated through bearing 82 and circumferential rail 84. Pressurized sea water enters at 70 and passes by passages 72, 74 to annular space 54. Sea water of lower salt concentration passes through membrane 58 into space 61 and some of this middling brine is removed through passages 76, 78 and 80 to be recycled as required with feed; the rest passes through membrane 62 and leaves through 68 and 81 to provide the product water having e.g. a salinity of 400 p.p.m. in a yield of 30% of the feed of initial salinity of 35,000 p.p.m. Brine leaves the vessel by passage 20. Other embodiments are described in which the feed passes to separate dividers in parallel. The membrane supports may be circular or polygonal in cross-section and cylindrical or frusto-conical (to inhibit solid material from settling on the surface) in elevation. Fig. I (not shown) is a flow-sheet which is largely self-explanatory, illustrating the use of the apparatus. The osmotic membranes employed are suitably of cellulose acetate and the manner in which the membrane is mounted on the support, suitably with a layer of filter material sandwiched between, is described in detail. The apparatus may also be applied to the recovery of water from sewage. From time to time, the membrane may require to be cleared of solid material or crystals. This may be done by back-flushing by allowing pressure to rise on the output side of the membrane, by shutting off the output and introducing high pressure water on the output side of the membrane. but most expeditiously by the "water-hasser" effect induced by suddenly and very rapidly closing the output line.
