Filed: 1976-04-30
Abstract: 1505026 Electro-forming metallic screens FRITZ BUSER AG 30 April 1976 [2 May 1975] 17598/76 Heading C7B A metallic (Ni) screen is electro-formed on a matrix having conducting and non-conducting portions, metal deposition being effected in at least two stages between each of which, except the last, the sides of the layer just deposited, which bound the spaces forming the screen openings, are covered by an insulating material. The screen may be for printing, the matrix being formed by use of a non-conducting photo-resist. The insulating material may be a varnish sprayed on, or a material applied to fill the spaces. The tops of the metal layers may be ground before the following deposition step.

Abstract: 939,188. Distilling sea water. NINEX INGENIOR A. S. May 8, 1962 [May 13, 1961], No. 17599/62. Class 32 In a plant for distilling sea water under vacuum on board ship wherein the cooling water of the ship's engine 1 is used as heating- medium in heat-exchanger 4 to boil sea water introduced into the heat-exchanger through line 5, and the boiling sea water flows into liquid/vapour separator 7, the separated steam enters condenser 10 where it is condensed by direct contact with a spray of distilled water which has been previously cooled by heat exchange with sea water in a heat-exchanger of the plate type 13. The distilled water is circulated around the circuit comprising the condenser 10 and one of the flow-paths of heatexchanger 13 by means of pump 12; and sea water is supplied through inlet 16 to the other flow-path of heat-exchanger 13. The distilled water product is pumped out of the condenser through outlet 18. The residual brine is withdrawn from separator 7 via outlet 8.

Title: Improved production of magnesia
IPC: C01F5/06
Filed: 1938-06-14
Abstract: 503,291. Magnesia; calcium carbonate. DYNAMIDON - WERK ENGELHORN & CO., GES. June 14, 1938, No. 17654. Convention date, Juna 14, 1937. [Class 1 (iii)] Magnesia is separated from mixtures with alkaline earth oxides by lixiviation with an excess of phenolic reagent and a solvent, the alkaline earth forming a soluble phenolate which is removed in solution while the magnesia remains with the impurities as a sludge. Examples of raw materials are calcined dolomite calcareous magnesite or lime-containing magnesia; of phenolic reagents are phenol or its homologues or their salts with bases more feeble than the alkaline earths, such as ammonia or pyridine ; and of solvents are water, alcohols or acetone. The lixiviation may be carried out at ordinary temperatures or at 40-60‹ C. Below 50‹ C. magnesia remains substantially unhydrated. In both cases vigorous stirring is necessary, while the reagent need not necessarily be completely dissolved in the solvent. The magnesia sludge has all traces of phenolic reagent removed by washing with a solvent or by steam distillation and may be then used for refractories, or further purification may be carried out by elutriation or washing with dilute hydrochloric acid. The liquor containing the alkaline earth phenolate is treated with an acid forming an insoluble alkaline earth salt, for example carbon dioxide under pressure or sulphuric acid. The precipitate may be freed from residual phenolic reagent as was the magnesia sludge, while the regenerated phenolic reagent and its solvent may be used on a further quantity of raw material.

Abstract: 1,175,836. Electromagnetic pumps and MHD generators. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 24 April, 1967 [22 April, 1966], No. 17778/66. Heading H2A. [Also in Division G6] A stream of liquid metal, e.g. sodium, coolant by-passes the core of a nuclear reactor by way of a rectangular section duct 87 within a square-section duct 83, these ducts being between the polepieces of a stack of permanent magnets 89. Since flow is forced in the inner duct 87, the magnetic field applied by the magnet assembly perpendicular to the longer sides of the duct 87 causes an e.m.f. to be set up, parallel to these sides, due to the interaction of the moving metal with the applied field. This e.m.f also appears in the portions of the square-section duct 83 flanking the duct 87 and causes an electric current to circulate. This current interacts with the applied magnetic field to produce a sample coolant flow in these portions of the duct 83 in the same direction as the coolant flow in the duct 87.

Abstract: 595,988. Helicopters. FAIREY AVIATION CO., Ltd., and BENNETT, J. A. J. July 12, 1945, No. 17832. [Class 4] A helicopter rotor comprises a single blade counterweighted for rotational balance and rigidly mounted without freedom to flap or to lag relatively to the counterweight, the blade, or a control surface on the blade, being provided with a feathering pivot so that the blade pitch, or blade surface angle, may be varied sinusoidally for control purposes. The blade may be sufficiently flexible to allow inclination of the blade-tip path relative to a plane normal to the axis of rotation. As shown, a rotary hub c is mounted in bearings d in a fixed hub a mounted on a support b, and is formed with apertured lugs e provided with bearings f for trunnions g on a frame h, the root of the blade k and the root m of a counterweight n being fixed in the trunnions g.

The latter is rotatable about an axis V-V in a sleeve w pivoted to the support b about a perpendicular axis. Movement of the rod t produces an inclination of the frame h and a sinusoidal variation of blade pitch.

Abstract: 205,854. Fuller, D. June 29, 1922. Brushes combined with soap - holders; stocks. - A frame B, Fig. 1, formed with a projecting portion carrying a row of bristles A, is provided with a recess to hold soap or cleansing material C, which lathers the finger-tips and acts as a guide therefor when the walls are being cleaned. The soap may be adjusted by means of a hole formed in the bottom of the frame through which a finger may be inserted to raise the soap, the latter being supported, when adjusted, by transverse pegs passed through holes D. The soap may be supported otherwise by means of rigid or flexible projections or irregularities provided on the soap or on the frame, or by U-shaped springs with bent ends engaging depressions in the sides of the frame. The base of the frame may be provided with an additional brush. In the construction shown in Fig. 14, the bristles A overlap part of the soap C, which is fitted in a recess formed right through the frame B. An additional brush N may be detachably secured to the frame by means of spring catches O. Pins on the brush N engage recesses in the frame B to prevent lateral displacement. Where no additional brush is provided the soap C may be held in position by means of transverse pegs or by a rubber sheet fitting tightly in the frame B.

Ltd. 19 April, 1967 [25 April, 1966; 4 May, 1966; 31 May, 1966; 17 Aug., 1966; 31 Aug., 1966; 29 Oct., 1966], No. 17920/67. Heading H5H. A glass melting bath 8 comprises a pair of electrodes 10, 11 mounted near the surface of the glass, the electrode 11 comprising a plurality of short sections connected by individual ballasts RT to a supply E. The bath is initially heated by a burner flame to render the glass conductive prior to connecting the bath to source E. Initially the surface temperature of the bath is non- uniform so that the resistance is non-uniform. However, the ballasts RT ensure that the current flow is substantially uniform by controlling the voltages applied to the electrode 10 and individual sections of electrode 11. To prevent current flow between adjacent short sections which have different voltages water cooled plates are inserted between the electrode sections to reduce the glass conductivity.
