Patent GB-1358776-A (GB)
Title: Method of electroslag casting of ingots
IPC: B22D23/10
Filed: 1972-06-09
Abstract: 1358776 Casting processes INSTITUT ELEKTROSVARKI IMENI E O PATONA AKADEMII NAUK UKRAINSKOI SSR 9 June 1972 [11 June 1971] 27131/72 Heading B3F A method of casting a large (e.g. 190 tonne) ingot comprises supplying slag to a mould, the slag being either molten or melted in the mould, heating the slag by an electric current supplied thereto by electrodes and pouring a plurality of discrete charges of molten metal into the mould, each charge comprising 5 to 25% by weight of the ingot to be cast. The charges are preferably complete heats (e.g. 10 tonne) from electric arc furnaces. Apart from the first charge, each subsequent charge is poured on to the molten surface of the previous charge, when the previous charge is at least half-solidified. The solidification of the metal proceeds from the base upwardly with mixing of the metal of subsequent heats. The mixing may be enhanced and the formation of a metal shell and slag sheath about the rim of an ingot inhibited by providing several (e.g. 6) electrodes about the circumference of the mould and reciprocating the mould about its vertical axis during solidification. After the last charge has been poured the electrodes are moved towards the centre of the ingot to avoid the formation of pipe.

Title: Improvements in and relating to means for trapping or foiling burglars
IPC: H04Q1/04
Filed: 1923-06-30
Abstract: 220,826. Murphy, J. J. June 30, 1923. Sliding doors.-A means for trapping or foiling burglars comprises a gate or extra door 1 normally fitting in a recess 2 above a doorway; it has secured at its lower end 4 cables, ropes, or chains 3 that pass over stationary pulleys 5 to pulleys 12, from which weights 11 hang, and then are secured to the wall of the building. The weight of the door normally overbalances the pull of the weights 11 but the pulleys 5 carry ratchet wheels with which pawls 7 engage, thus preventing the door sliding down. Should it be desired to close the door to trap a burglar or to prevent one from entering the building, the pawl is raised by energizing ,a solenoid 14 by completing a circuit through a conveniently-placed switch. Catches 23 prevent the door being raised after it has fallen and shock-absorbers may be provided to cushion the fall. As the door falls it may complete a circuit causing an alarm to be sounded in a police station. In' a modification, the door slides horizontally, being pulled out of a recess by the fall of a weight. The door in this case may be of expansible latticework. In another modification, a latticework door may be expanded laterally by the operation of an hydraulic piston.

Abstract: 385,374. Ball or tube mills. TOLLEMACHE, H. D., 4, Norfolk Street, Strand, London. Oct. 1, 1931, No. 27310. [Class.59.] In a mill the air-borne pulverized particles are discharged into the separator at a point above the bottom and the coarse particles deposited in the separator are led through a shielded shoot to the bottom from whence they are raised into the discharge passage and are returned by a screw conveyer back to the grinding zone of the mill. As shown in Fig. 1, the rotary drum A is supported on an inlet trunnion A<1> and an outlet trunnion A<2> provided with a scoop H for raising coarse particles from a classifier C to the trunnion, from which it is returned to the drum by a worm G. The free edge of the worm may be provided with a flange G<1>, Fig. 3, or may be inclined to prevent the coarse particles being carried out of the trunnion with the air blast. The classifier comprises a tapered casing provided with partitions D, Fig. 2, converging to a shielded duct D<1> which leads the coarse particles to a recess F in which the scoop H rotates. The ground material is carried by the air blast over the top of the partitions D and around adjustable partitions C<4>, which may be pivoted, to an outlet E.

Title: Improvements in or relating to the manufacture of composite calcium sulphate/zinc sulphide pigments
IPC: C09C1/06
Filed: 1948-10-21
Abstract: A composite calcium sulphate, zinc sulphide white pigment is prepared by reacting zinc sulphate and calcium hydrosulphide using an excess of soluble zinc, the soluble calcium sulphide being eliminated without the introduction of free sulphuric acid, and then calcining the product.  The process may be carried out by adding to the product before calcining a small portion of zinc sulphate followed after a short interval by adding calcium carbonate slurry, zinc sulphate and calcium carbonate additions being continued until the elimination of hydrogen sulphide and free sulphuric acid is complete when a final excess of zinc sulphate solution may be added.  This excess may be sufficient to produce a pH of about four while a small amount of cobalt ammonium sulphate may be added to the zinc sulphate.  Air may be admitted to the calcining furnace to eliminate calcium sulphide but is kept at a minimum to avoid zinc oxide formation; the calcined product may be quenched with water to form a slurry and sulphuric or other mineral acid added until the slurry reacts acid to an indicating means, preferably methyl orange.

Patent GB-739219-A (GB)
Title: Method of obtaining concentrated monoglyceride products
IPC: C11C3/06
Filed: 1953-10-09
Abstract: Concentrated fatty acid monoglyceride products are obtained by a process comprising extracting a material, containing fatty acid monoglyceride and other fatty material, with methyl alcohol containing not more than 10 per cent water and further extracting the resulting extract with methyl alcohol containing from about 30 to 60 per cent water.  The starting material may be obtained by reacting a triglyceride fat or a fat-forming fatty acid with glycerin.  Suitable fatty materials include cottonseed oil, lard, peanut oil, butterfat, oleic acid, stearic acid, corn oil, coconut oil, palmitic acid, tallow, soyabean oil and myristic acid. Preferably a transesterification catalyst, such as monovalent metal hydrides and hydroxides and bivalent metal oxides and hydroxides, is present during the formation of the monoglyceride-containing material. Preferably the unreacted glycerin is removed from the mixture before subjecting it to extraction with the aqueous methyl alcohol.  During the extractions it is advantageous to stabilize the mixture by the addition of a fat antioxidant such as hydroquinone or butylated hydroxy anisole.  Phospholipids, which may be present in the fatty material to be extracted, can be removed by treating the material with acetone.  In an example lard is treated with glycerin in the presence of sodium hydroxide; the resulting mixture was dissolved in ether, the solution washed and dried and the ether then evaporated, phospholipids were removed by treating the ether-soluble fraction with acetone; the resulting glycerin-depleted reaction product was extracted with 95 per cent aqueous methyl alcohol and the alcohol solution was then diluted with water until the methanol was of 70 per cent concentration; the alcohol phase was separated and the alcohol removed by evaporation leaving lard monoglycerides of high purity.

Abstract: 773,687. Multiplex systems. TELEPHONE MANUFACTURING CO., Ltd. Sept. 21, 1955 [Sept. 27, 1954], No. 27871/54. Class 40 (4). In a multiplex system wherein signalling is effected by a current having a frequency outside the respective speech bands, false signalling by the modulation products of adjacent channels is avoided by the inclusion in the transmission apparatus of the audio-frequency equipment of a high pass filter 9 having a cut-off frequency below the lowest required audio frequency of the respective band. The effectiveness of the arrangement in systems using symmetric and assymetric band-pass filters 4 and sub-audio or supra-audio signalling frequencies is discussed with reference to Figs. 4 and 5 (not shown). The signalling currents may be injected before or after the sideband selecting band-pass filter according to the filter cut-off characteristics. Signalling currents in the channel equipment shown are received by a relay A and modulated separately in a modulator 12 by the output of channel oscillator 13, the sideband selected by filter 14 being applied to the send channel beyond filter 4. In this system the received signalling currents are extracted before the receive band-pass filter 5.
