Title: Improvements in and relating to the production of an antibiotic
Filed: 1947-04-21
Abstract: In the recovery of an antibiotic from the metabolism fluid of the bacillus known as B. aerosporus Greer or B. polymyoca (Praymowski) Migula, by the process of Specification 619,572, the first treatment with charcoal is preceded by heating under acid conditions, preferably in the presence of hydrochloric acid (e.g. 2 per cent by weight of the mixture of 40 per cent hydrochloric acid), or sulphuric acid.  The time and temperature of heating (e.g. 30 minutes at 80 DEG C.) and the acidity (pH below 6, preferably about 2.5) should be such that at least 90 per cent of the gummy impurity present is converted into a non-gummy form while leaving at least 90 per cent of the antibiotic activity unimpaired.  If the metabolism fluid already has a pH below 6, the addition of further acid, though desirable, is not essential.

IPC: B63B23/18
Abstract: 106,698. Welin, A. June 21, 1916. Davits.-Sluing davits are coupled together and operated by rope tackle arranged so that a continuous pull on a rope moves the davits successively to their outboard positions. In the arrangement shown, the davits are connected bv a rod A pivoted to the forward davit, or, according to the Provisional Specifications, to a bracket thereon, sliding on a pin or through an eye on the rear davit, a rope E being secured to brackets G, F on the davit and arm to hold the pin C against the inner end of the slot in the inboard position. The rod may be replaced by a rope secured to the head of the forward davit and passed over the head of the rear davit to a point on the arm. In a modification, the rod is pivoted to the rear davit and to a bracket on the front davit. According to the Provisional Specification 8747/16, the bracket is arranged so that the point of attachment to the rod is slightly outboard of the plane passing through the davit axis and the other davit head In a further modification, the rod is pivoted to the head of the front davit and to a point on the arm of the rear davit. The rear davit D has a rearwardly projecting arm L provided with a sheave M, while the forward davit B has a projecting arm H fitted with a sheave I and with a pivoted arm J normally held against a stop and having a double sheave K. The operating-rope passes from a fixed point 0, round the sheave M, over a guide-pulley P, round one of the sheaves K, over the pulley I, and finally over the second pulley K, to a gun-tackle Q. According to the Provisional Specification 8747/16, the pulley M may be dispensed with and the line made fast to the arm L, or the line may be secured to a becket on a fixed guide-pulley and pass round the pulley M, round a second sheave on the arm, and then over a second pulley M. In another modification, the pulley M is mounted on an arm pivoted to the arm L, and the pulleys I, K are replaced by a single pulley K on the arm J. In this form, the operating-rope passes from a becket on the pulley K, over a guide-pulley, and round the pulleys M, K. In a further modification, the rear davit has an arm projecting forward and inboard, to which a second arm, projecting outboard and carrying the pulley M, is fitted. The operating-cord passes from a becket in the pulley K, over a guide-pulley abaft the davit, over the pulley M, back over the guide-pulley, and round the pulley K. According to the Provisional Specification 9247/16, the davits are both provided with forwardly projecting arms having sheaves, the operating-rope passing from a fixed point slightly aft and inboard of the rear davit, round the sheave on the rear, over a guide-pulley at the fixed point, and then round the sheave on the forward davit.

Abstract: 955,635. Storing and feeding fibres. T.M.M. (RESEARCH) Ltd. March 8, 1963 [March 20, 1962], No. 10690/62 Heading D1N . Apparatus such as a hopper feeder for temporary storage of fibres and for feeding them to a subsequent processing stage includes two parallel horizontal lattices arranged to carry fibres between them to a vertical spiked lattice. The upper horizontal lattice F is shorter than the lower lattice E to'allow fibres from a pneumatic duct and screen BA to fall on to the lower lattice. A stripping lattice H removes large lumps or excess of material from the vertical lattice D and a guard member J prevents fibres removed by the stripping lattice from passing directly back to the vertical lattice. When there is an excess of material within the storage space C, a swinging door or other means responsive to the height of material operates to stop the supply of fibres from previous machines.

Filed: 1950-05-03
Abstract: 672,437. Heating air. ROBINSON. A. P. May 3, 1950, No. 10898/50. Class 64(iii) In a portable air heater, e.g. of welded sheet metal, for positioning within a domestic firebox 10 to seal the entrance thereof, a firebox 16 with a smoke outlet 35 to the fireplace flue 11, Fig. 3, is spaced from an enclosing casing providing connected air heating passages 67 to which air flows in beneath the firebox to pass back to the room through an outlet above. Further, a smoke chamber 40, formed on the back wall 29 of the casing, is closed by a detachable bottom wall 42 but opens at the top to the flue 11. Furthermore, smoke from the outlet 35, when a pivoted damper 48 is in the position shown in Fig. 3, passes down ' through the smoke chamber between two partition walls 44 and out to the flue 11 up two outer passages 47, Fig 4, which in a modification, Fig. 4a (not shown), extend round the outside of the side air passages 67. For increased draught when lighting, a rod 50 is used to push the damper 48 into the position shown faintly in Fig. 3 to permit smoke to byepass the chamber 40 to the flue. The side walls 21, Fig. 4, of the firebox slope inwards from the bottom to the top so that air entering the casing past fixed louvres 31, Fig. 3, passes into side passages 67 which increase in size upwardly. The air then flows into the top passage between an inclined top wall 20 of the firebox and a top wall 28 of the casing, which passage thus also increases in size in the direction of the heated air flow to the fixed outlet louvres 32. Flanges 56, 60 formed on the sides and top of the front of the air heater are sealed against the edges of the fireplace with rock wool 69. Ashes from a grate 71 discharge through a tube 55 normally covered by a plate at the bottom of the firebox 16. An air blower may be installed in the air intake opening.

Title: Improvements in or relating to airplane trim control
Inventor: FEENEY THOMAS AQUINAS
IPC: B64C13/00
Filed: 1953-04-21
Abstract: 743,541. Controlling aircraft. NORTHROP AIRCRAFT, Inc. April 21, 1953, No. 10910/53. Class 4. In an aircraft provided with power-operated control surfaces and elastic means to provide the pilot with a sense of " feel " when operating a control member, powered means are incorporated whereby the neutral position of the control member may be adjusted to compensate for out-of-trim positions of the surfaces. The invention may be applied to the control systems of any of the movable control surfaces and in the embodiment shown it is incorporated in the mechanism for the rudder. The rudder bar pillar 1, pivotally mounted in a fixed plate 3, carries an arm 4 which is coupled to, and normally is held in neutral position by, the central movable rod 5 of a double-acting spring box 14. The other end of the box 14 is pivoted to one end of an arm 17 mounted on a fixed pivot 18 and connected at its other end to a screw-operated extensible link 20, 21 which is operated by a reversible electric motor 22 through a gear-box 23, the gear-box being anchored to the plate 3. Limit switches 25, 26, actuated by movement of the end caps of the spring box 14, and a master switch in the handle of the control column (not shown) are connected in a circuit with the motor 22 and a power source (not shown). Movement, by the pilot, of the rudder bar to trim the aircraft will cause relative movement of the elements of the spring box 14 to close one or the other of the switches 25, 26, and to restore the rudder bar to its neutral position with the rudder in a trimmed attitude, the pilot closes the switch in the control column to complete the power circuit to the motor 22 which will be energized to lengthen or shorten the link 20, 21.

Title: Improvements in method and apparatus for continuously removing oleaginous and foreign substances from webs of fibrous material
Filed: 1939-04-11
Abstract: 527,416. Dry-cleaning. HUGHES, R. M. (Stevens & Sons Co., M. T.). April 11, 1939. No. 11017. [Class 91] After cleaning a continuous web of fibrous material by passage through a bath of liquid solvent the main portion of the solvent and impurities is removed by passing the web through a narrow transverse zone in which the pressure on one side is less than on the other ; the remaining solvent may then be evaporated off. For example, a length of cloth 2 is passed between brushes 3 to remove loose fibres, around rolls 9, 10, and through a seal 13 of flexible members 12, to rolls 19, 20 in the solvent compartments A, B, C, of an extractor 11 ; after passing over and between guide rolls 21 it is drawn over a slot in the top of a transverse tube 51 connected to a vacuum pump 58 by a pipe 55 and a filter 57 containing a sieve 59 ; the cloth is taken out of the extractor through a seal 16 into a chamber 25, where it is freed from residual solvent by passage over feed rolls 37, 36 and steam-heated rolls 26-30; it is led out over a guide roll 38 and through a narrow passage 39 to feed rolls 40. Trichlorethylene is supplied continuously from a tank 44 and a pipe 45 through a rotometer 47 to the deepest bath C, overflows to the baths B, A, and is passed through a valve 49, and pipes 48, 73, 74 to a still 50. The still also receives any residues or deposits in the compartments A. B, C via pipes 114, 73 and 74. The vacuum pump 58 discharges the liquid extract solution and solvent vapour received from the suction tube 51 to a cooler 61 by means of a tube 60; solvent vapour is taken by a pipe 62 to the extraction chamber 11; liquid is discharged through a pipe 63 and, according to its condition, is (1) returned to extractor compartment B through a valve 65 ; or (2) conducted to the still 50 through a pipe 64, valve 67, and pipes 66, 73, 74 ; or (3) taken to a sump 70 through pipe 64, a valve 69, and pipes 68, 103. When the still 50 is heated by coils 79 or by direct steam from a pipe 85 the vapours flow through a pipe 81 to a condenser 82; by a pipe 72 the condenser also receives the solvent evaporated from the cloth in the chamber 25. Condensed solvent flows through a pipe 104 to a cooler 91, thence by a pipe 105 to a water separator 96, and by pipes 99, 103, to the sump 40 ; it is returned to the tank 44 by a pump 111 controlled by a float 110. Water is discharged from the separator 96 by a pipe 98. If water condenses in the cooler 91 it may be removed through a pipe 108 to the separator 96. Solvents specified are carbon tetrachloride, trichlorethylene, tetrachlorethylene, and any mixture thereof, with or without smaller quantities of inflammable solvents. The apparatus is made or lined with stainless steel or other material resisting corrosion. Specification 29764/06, [Class 91], is referred to.

Title: Improvements relating to high-voltage electric transformer
IPC: H01F38/26
Filed: 1953-04-22
Abstract: 726,003. Transformers. REYROLLE & CO., Ltd., A., and MOSER-GLASER & CO. AKT.- GES. April 22, 1953 [April 24, 1952], No. 11034/53. Class 38 (2). A high voltage transformer has its entire insulation provided by non-liquid materials and comprises an elongated magnetic core 1 closely surrounded by a primary winding 4, a high voltage winding being divided into at least two sections as 5, 6 and 7-which surround the core and are spaced apart along its length, each winding section being enclosed in separate insulating members 8, 9 and 10 of generally tubular shape, each insulating member being provided with inner and outer surface coatings 8a, 8b; 9a, 9b; 10a, 10b; of electrically conductive material, the members being so arranged that the inner surface coating of one member, e.g. 10b, is electrically connected-as at 11-to the outer surface coating 9a of an adjacent member. The ends of the winding embedded in each insulating member are connected one to the outer surface coating-as by a connection 13-and the other to the inner surface coating, thus when the members are telescopically assembled a circuit exists through the high-voltage winding from the high-voltage terminal 12 which is electrically connected to the surface coating 10a. The spaces 16 between the members 8, 9 and 10 may be left free for the circulation of air for cooling purposes or the spaces may be filled with a fire-extinguishing material. The core 1 is provided with enlarged cross-sections 2, 3 at the ends thereof which project by a distance at least equal to the thickness of the primary winding 4 thereby assisting the passage of the magnetic flux in the air part of the magnetic path. Since an open circuit iron core of this type requires a high magnetizing current, the insulating members are formed of a material having a high dielectric constant, e.g. greater than six, to mitigate this disadvantage. The outside surfaces of the lower parts of the insulating members 8, 9 and 10 may be formed by one or more water sheds 17.

Title: Process for the production of rubber articles
IPC: B29C37/00
Filed: 1935-04-10
Abstract: Moulded articles comprising masticated rubber or the like compositions, provided with a superficial coating of rubber or the like deposited from aqueous dispersions thereof are produced by treating the whole or a part of the moulding surface of a mould with one or more of the aqueous dispersions, solidifying the resulting coating, introducing the masticated rubber composition into the mould, moulding the composition and vulcanizing the whole under pressure in the mould.  The superficial coating of rubber may be for protective or decorative purposes; the process may be applied to the manufacture of floor covering material, conveyer belts, tyre covers &c., provided on their surface with lettering, distinguishing marks &c.  The aqueous dispersions may be natural or artificial, they may be coloured and may contain wetting agents, such as soaps and sulphonic acids, and material capable of increasing the viscosity of the dispersion such as sodium silicate.  The dispersion may be sprayed or painted or spread on the moulding surface if desired with the interposition of a suitable stencil; alternatively the mould may be merely filled with a dispersion and then emptied leaving a thin film of dispersion over the whole surface.  The coating is then dried in air which may be warmed; the operation may be repeated until the desired thickness is obtained.  The mould may be provided with indented or engraved designs which may be filled with the aqueous dispersions.  The moulded articles may be provided with fibrous, fabric or other backings or inserts.  Specifications 219,635 and 290,313, [both in Class 70], are referred to.

Title: Improvements in and relating to electrolytic cells
IPC: C25B9/19
Filed: 1941-09-01
Abstract: 544,608. Electrolytic cells. SHAWINIGAN CHEMICALS, Ltd. Sept. 1, 1941, No. 11120. Convention date, Sept. 10, 1940. [Class 41] An electrolytic cell comprises three adjoining upper chambers 50, 60, 90, spaced from a fourth chamber 10 by a series of tubular electrodes enclosed in a cylindrical casing, not shown, forming a compartment for the circulation of cooling liquid. The lowermost chamber or header 10, provided with a catholyte inlet 15, is bolted to a graphite member 20 in which the lower ends of the cathode tubes 30 are set, the upper ends being engaged in a similar member 40. The chamber 10 carries a porcelain or other non- conducting perforated plate 17 on which rest semi-permeable diaphragm tubes 110 of an aluminium oxide composition, these supporting in turn by means of spacers 112, the hollow graphite anodes 80. The upper ends of the diaphragms are received in openings in the base of the chamber 60, the anodes extending up to bushings in a member 70 which constitutes the base of the uppermost or gas chamber 90. The positive and negative current connections are made with the parts 70, 40 respectively. The cell may be used for the production of chromous chloride and chlorine in the manufacture of ethylene chlorhydriri. An aqueous solution of the catholyte, chromic chloride, is pumped into chamber 10 from which it flows between the surfaces of the cathodes and the diaphragms, emerging from the outlet 55 to return to the storage tank. The anolyte, a solution of HC1 which may contain some CrC13, enters by the tube 62, and flows down through the hollow anodes into the compartment space between the anodes and the diaphragms into the chamber 60 to return through tube 65 to the storage tank. Chlorine evolved at the anodes passes through pipe 61 into the gas dome 90 and is collected from pipe 63. Hydrogen ions produced at the cathodes reduce the chromic chloride to chromous chloride, the issuing catholyte being circulated through a tower against a stream of acetylene which is thus hydrogenated to ethylene. Catholyte and anolyte are both replenished with HC1 before re-entry. The ethylene and chlorine produced are subsequently re-acted to form ethylene chlorhydrin.
