Title: Improvements relating to methods of manufacturing loaded electrical conductors
IPC: H01B11/14
Filed: 1932-04-23
Abstract: 400,271. Loaded conductors; electrodeposition. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Bishop, W. M. ; 16, Pine Street, Douglaston, New York, U.S.A.) April 23, 1932, No. 11706: Convention date, May 20, 1931. [Classes 36 and 41.] To provide looseness between the conductor and an electrolytically-deposited or sprayed-on magnetic loading sheath of a signalling cable, the conductor is provided with a metallic spacing layer upon which the loading material is applied, the spacing layer being subsequently removed through gaps formed in the loading sheath. In one construction, a conductor 50, Fig. 5, formed of deoxidized copper prepared by the method described in Specification 340,497, [Group II], is provided with an electrolyticallydeposited zinc or magnesium spacing sheath 51 upon which is deposited a loading sheath 52 formed of an alloy of nickel and iron, with or without cobalt. The loading sheath may be applied by passing the coated conductor 51 through an electrolytic plating bath 31, Fig. 3, having iron, nickel and cobalt anodes 34, 35, 36, the conductor 51 forming the cathode. The electrolyte of the bath contains soluble sulphates and chlorides of the metals to be deposited, together with a "buffer" mixture consisting of one part by weight of boric acid and five parts by weight of sodium sulphate. The loaded conductor thus formed is stretched by the apparatus described in Specification 353,472 to cause frequent transverse breaks 53, Fig. 5, in the loading sheath 52 and is then placed as a coil in a bath of sulphuric or hydrochloric acid to remove the spacing sheath 51. Alternatively, the spacing sheath may be removed by heating the stretched conductor in air or in a rarefied atmosphere. Fig. 7 shows apparatus for carrying out the latter method, comprising a resistance furnace 65 containing a closable quartz tube 61 which is adapted to be exhausted through a pipe 63. The conductor to be treated is wound on a quartz tube 60 and inserted within the tube 61, a heat-resisting baffle 64 being disposed as shown.

Title: Cooled metallic combustion chamber for the production of heating and driving gases
IPC: F23R3/00
Filed: 1948-04-29
Abstract: 647,293. Generating combustion products under pressure. AKT.-GES. BROWN, BOVERI, & CIE. April 29, 1948, No. 11774. Convention date, May 12, 1947. [Class 51(i)] A combustion chamber 8 for a gas turbine plant is provided with a flame tube consisting of a casing 7 from which are freely suspended a plurality of interchangeable ribbed elements the inner surfaces 10 of which are contacted by the flames. The ribs and the casing 7 are cooled by the secondary air flow. Attached to the ribs 11 are lugs 12 which engage openings 13 in the casing 7, the latter consisting of a number of sheet metal cylinders graded in diameter and suspended from starshaped holders 16. A radial clearance between the cylinder and holders allows for radial expansion. The spaces between the ribs 11 allows the cooling air to flow from the space 6 into the inside of the combustion chamber. In a modification, Fig. 3, the combustion chamber wall is formed of a number of conical overlapping sleeves 17 mutually supported by means of lugs 18. The bottom ring rests oh a bracket 19 fixed to the outer casing 8. The ribbed elements 20 in this case are trapezoidal in shape. In this construction the individual parts for all the combustion chamber sections are the same size. In another modification the ribbed elements consist of a straight part forming the combustion chamber wall and an inclined part which forms annular inlets for the cooling air. In this arrangement the ribbed elements are hooked on to supporting rings. In a further modification the casing 7 is formed as a cylinder and encloses a number of annular ribbed elements which are axially spaced along the casing leaving annular slots between them. Holes are formed in the casing 7 to allow cooling air to flow into the casing, over the ribs of the ribbed elements and through the annular slots into the combustion chamber. The ribbed elements may be flat or curved to fit the combustion chamber. To avoid distortion of the elements due to differences of temperature on opposite sides, the ribs may be divided along their length. The area of the cooling air passages between the ribs may be varied so as to accelerate the air flow as the air gets hotter. This maintains the wall temperature of the ribbed element constant. The ribbed elements may be made of chrome steel. These ribs may be machined in the element or bent up out of sheet metal. The Specification as open to inspection under Sect. 91 comprises also a construction of ribbed element consisting of thick chrome steel on the flame side, thin sheet metal bent in the form of ribs on the cooling air side, the enclosed space being filled with cast copper. This subject-matter does not appear in the Specification as accepted.

Title: Method of and apparatus for pasteurising and deodorising lacteal liquids
IPC: A23C3/037
Filed: 1933-04-24
Abstract: 418,591. Pasteurizing and deodorizing lacteal liquids. MURRAY DEODORISERS, Ltd., Room 23, G.P.O. Building, Auckland, New Zealand.-(Assignees of Murray, H. L. ; 15, King Edward Avenue, Epsom, Auckland, New Zealand.) April 24, 1933, Nos. 11932/33, 11934/33, and 13741/34. Convention dates, July 20, 1932, Jan. 23, 1933, and April 24, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 27, 1933.] [Class 49.] In a continuous process for the pasteurization and deodorization of lacteal liquids such as cream, the liquid passes continuously through a flash pasteurizer 1 and a deodorizer 7 which are under vacuum from a common source, the liquid being drawn from the pasteurizer 1 by the pull of vacuum evacuating the deodorizer 7. As shown, the inlet end 2 of the pasteurizer 1, which is of the kind set out in Specification 413,460 in which steam is diffused into the liquid, is connected to a float tank 3 which may be of the kind described in Specification 220,627, [Class 49], and which is supplied with the liquid from a pipe 4 which preferably has a strainer. The pasteurizer 1 is vertically disposed so that its outlet 5 can be connected to the steam scrubber pipe 6 of the deodorizer 7 which may be of the kind described in Specification 404,729, the pipe 6 terminating in a fishtail 8. The liquid raised to pasteurizing chamber together with the excess steam supplied to the pasteurizer for use in the subsequent deodorization is drawn by the vacuum in a frothy state through pipe 6 into the deodorizer 7 in which after deodorization it may be retarded for a desired period to complete the pasteurization by a baffle ring 12 and an extension 10 of the outlet 9. Means may be provided for automatically varying the ratio between the vacuum in the pasteurizer and in the deodorizer, consisting of a cylinder having large and small portions 15, 16, Fig. 3, with large and small pistons 18, 19 respectively connected to one piston rod 20 which actuates a butterfly valve 27 in the pipe 6 through a connecting rod 25 and a lever 26. The upper end of cylinder 15 has a cover 21 from which a pipe 22 extends to a suitable point on the pasteurizer. The space 17 between the pistons 18, 19 is connected by a pipe 23 to the deodorizer 7. The rod 25 has a shoulder 28 to receive removable weights 29. The areas of the pistons correspond to the degrees of vacuum in the pasteurizer and deodorizer respectively, the larger piston 18 corresponding to the lower degree of vacuum in the pasteurizer, and so long as the balance is maintained the valve 27 will remain open. If the vacuum in the pasteurizer increases, the piston 18 will be moved upwards causing closing of the valve 27 and restoration of the required ratio of vacuum. This ratio may be varied by varying the weights 29. To prevent rapid movement of the valve 27 dash pot means may be fitted to the rods 20 or 25, or the lever 26.

Patent GB-474244-A (GB)
Title: Improvements in or relating to the production of plastic materials in sheet form
IPC: B29C48/885
Filed: 1936-04-27
Abstract: Sheets obtained by extruding plastic material such as cellulose derivative compositions are passed through brine, the temperature of which is relatively low at the point where the sheet is introduced, and progressively increases along the path of travel of the sheet as the solvent content decreases, but is not allowed to rise sufficiently to cause distortion.  The seasoning of the sheet is continued further in air.  There may be used a plurality of baths of progressively increasing temperature.  The brine treatment may be continued until the greater part of the solvent has been removed leaving only about 3--5 per cent of volatile constituents comprising solvent and water.  The initial temperature may be below 15 DEG  C. The maximum temperature is varied according to the composition of the plastic material.  It is preferably at least 45 DEG  C. and may be as high as 70 DEG  C.  The brine baths may consist of sodium chloride solution of about 20 per cent strength.  Fresh brine may be added to the baths and used brine removed so as to maintain the solvent content in the bath at 1--3 per cent.  In an example, a plastic dough comprising cellulose nitrate, camphor, ethyl alcohol and acetone is extruded into cold brine.  The sheet travels through the bath and then successively through a large number of baths maintained at progressively higher temperatures, the final temperature applied to the sheet after six hours being 70 DEG  C.  The sheet is then seasoned for 2 hours in warm circulating air, and it may then be used for safety glass.  Other compositions specified are, cellulose acetate, dimethyl phthalate, diethyl phthalate, alcohol, and acetone, and cellulose acetate, dimethyl phthalate, ethyl alcohol, and methyl ethyl ketone.  Cellulose ether plastic compositions may also be used. Specification 393,957 is referred to.
