Title: Improvements in or relating to leakage control for centrifugal pump shaft seals
IPC: F04D9/02
Filed: 1952-10-14
Abstract: 707,521.. Centrifugal pumps. LA BOUR CO., Inc. Oct. 14, 1952 [July 26, 1952], No. 25760/52. Class 110(1) In a centrifugal pump. leakage of liquid through the shaft seal is prevented by restricting the flow of liquid in the pump inlet connection so that the liquid pressure at the inside of the shaft seal is maintained substantially at or below the pressure at the outside. The pump impeller 15 has a drum-like portion which co-operates with a stationary member 17 to form a kinetic seal for the impeller shaft 16 similar to that described in Specification 588,939. The pump inlet 5 is connected to a vacuum evaporator through a connection 20. The flow through the connection 20 is restricted by a balanced valve 23, comprising discs 28, 28a, which is held open, against a spring 35, by a diaphragm 30 exposed on its lower side to atmospheric pressure and on its upper side, by way of a pipe 33, to the pressure within the inlet 5. The evaporator is normally under a vacuum, and the valve 23 is then fully open. If the evaporator pressure rises above atmospheric, so that the pressure in the inlet 5, and hence on the inside of the shaft seal. tends to rise above atmospheric, the diaphragm 30 reduces the valve opening. The resultant pressure drop across the valve keeps the pressure in the inlet 5 below atmospheric. A needle valve or like flow-restriction 34 may be provided to reduce.or delay the effect of pressure fluctuations. The pump may be similar to that described in Specification 478,862, in which the shaft seal is a normal stuffing box. The valve 23 may be constructed as described in Specification 707,522, [Group XXIX]. Specification 153,783, [Class 110(1)], also is referred to.

Patent GB-1353355-A (GB)
Title: Metalcontaining fibrous material
IPC: D06Q1/04
Filed: 1971-04-19
Abstract: 1353355 Coating fibres with metals C DAVIDOFF 19 April 1971 [15 April 1970] 26173/71 Heading C7F [Also in Divisions B6 and D1] In discrete areas of a flexible fibrous sheet material woven from fibre units or yarns composed of electrically non-conductive and magnetically non-responsive continuous filaments, the filaments throughout the thickness of the material are individually coated with a substantially uniform film of electrically conductive or magnetically responsive metal. The material may be formed by selectively etching away the metal coating from the filaments of a material whose filaments are all metal coated. Alternatively the material may be formed by selective deposition of the metal. The filaments may be composed of glass, silk or synthetic organic polymers, copolymers and mixed polymers. Examples of suitable materials are given. The metal coating may be of silver, gold, platinum, palladium, copper, aluminium, nickel, cobalt, iron, titanium, molybdenum, chromium, tungsten, lead, tin, zinc, cadmium, manganese, antimony, germanium, indium, rhenium, ruthenium, rhodium, selenium, rare earth metals and mixtures and alloys of two or more of these. The filaments may be metallized by deposition from aqueous or organic solutions of metal salts or other reducible metal compounds. Alternatively the filaments may be "gas plated" wherein one or a mixture of heat-decomposable gaseous compounds of the selected metal or metals is thermally decomposed in situ on the surfaces of the fibres. The etching may be by means of dilute nitric acid (for silver, copper, cobalt, iron and nickel), hot or concentrated sulphuric acid (for silver, copper, cobalt, aluminium and palladium) and aqua regia (for gold and platinum). Sodium or potassium cyanide may also be used together with hydrogen peroxide, m-nitrobenzoic acid, and sodium m-nitrobenzenesulphonate as additives. Mild electrolytic action may be used to aid attack of the etchant. The selective attack may be accomplished by directing a jet of etchant only at areas where attack is desired or by use of a mask. The sheet may be clamped between apertured metal plates which permit attack only through the apertures. The inner surfaces of the plates may be coated with resilient material to act as a gasket to prevent seepage of the etchant. As an alternative to selective removal of metal from a metallized sheet, a non-metallized sheet may be selectively metallized by using the techniques described above for overall metallization but with the use of a suitable mask e.g. the apertured metal plates.  The products of the invention are stated to be suitable for use as capacitance circuits, antennas, dipoles, magnetically responsive elements, identification labelling, leads for connecting medical instruments (e.g. electrocardiac machines to the human body, electrical connections and recording tape.)

Patent GB-668817-A (GB)
Title: Production of sodium chlorite
IPC: C01B11/10
Filed: 1950-10-31
Abstract: In the production of sodium chlorite by reaction between chlorine dioxide and sodium hydroxide solution, the chlorate ion produced is removed from the reaction mixture as potassium chlorate.  This may be effected by treating a mixed solution of sodium and potassium hydroxides, or by adding potassium hydroxide after the reaction with sodium hydroxide.  In the second process, the precipitated potassium chlorate is removed and the resulting solution of sodium chlorite and hydroxide further treated with chlorine dioxide, the process being continued until the solution contains only a small amount of sodium chlorate; the latter is decomposed by the addition of potassium chloride and the potassium chlorate formed is separated.  The precipitation of potassium chlorate may be assisted by evaporation in vacuo.
