Title: Improvements in and relating to a method and apparatus for moulding phonograph records and like articles
IPC: B29D17/00
Filed: 1919-07-07
Abstract: 149,502. Errickson, J. V. July 7, 1919. Moulding phonograph records; cooling and heating plungers; pressing-plungers. - Moulding- presses, for duplicating phonograph records and like purposes, have the dies alternately heated and cooled by fluid passing in parallel through a number of curved paths close to the operating surface of the die. The openings for the fluid into the various paths are proportional to the lengths of these paths. The dies are formed in two parts abutting in a plane parallel to the face of the die, and the paths are formed in one of the abutting surfaces, the junction being sealed by insetting one part within the other. The central portion of the die face is slightly concave, and the rim portion slightly bevelled. Fig. 1 is a plan and Fig. 3 a sectional elevation of the lower die, the upper die being similar except that it has a central opening to receive the projecting spindle 8. Fig. 6 shows the underside of a disk forming part of the die. The die 1 has a central opening to receive a collar 4 which has a bevelled head 3 and is held in place by a screw 19, rod 20, and plug 18. The central pin 8 has a shoulder 7 engaging a shoulder on the upper end of the collar 4. A disk is cut away from the body of the die and a series of concentric channels 11 are cut in one or both of the abutting faces. The rim 13 of the disk is forced into a groove in the die by heavy pressure to prevent leakage, and the central opening is similarly forced over the hub 17. The inlet pipe 21 and the exhaust pipe 22 for the heating and cooling fluids communicate with radial passages 23 in the die body. Short drilled holes 25 connecting the pipes 21, 22 to the channels 11 are proportional in diameter to their distance from the centre of the die. The thin upper matrix is clamped on the top of the disk by the overhanging edge of a ring 29 secured by screws, and the central part is held by the bevel on the collar 4. The central part of the die face is slightly dished as shown at 32, 33, Fig. 7, and the rim 35, 36 is bevelled, leaving a raised surface 37, 38 at an intermediate point. Reference has been directed by the Comptroller to Specifications 147,865 and 147,866.

Patent GB-822094-A (GB)
Title: Flaring tool
IPC: B21D41/02
Filed: 1957-05-29
Abstract: 822,094. Tube expanders and flangers; spinning. IMPERIAL BRASS MANUFACTURING CO. May 29, 1957 [Aug. 10, 1956], No. 17028/57. Class 83 (4). A tube end is flared and burnished by means which may rotate and at the same time move axially of the tube to effect the flaring and may then rotate without moving axially to effect the burnishing. A chromium-plated faceted flaring and burnishing cone 15, fixed at one end of a rod 14 axially movable in a sleeve 12, is rotated and moved towards a tube end 20, held in a clamp 13 of a frame 11. This is effected by rotation of a handle 16 secured to the other end of the rod 14 and having a pin 17 thereon engaging a slot 18 in the sleeve 12 which is threaded in the frame 11, a spring 19 abutting a sleeve shoulder 12d and a cone shoulder 15a giving the cone 15 the axial movement of the sleeve 12. Alternatively, a pin on the sleeve 12 may engage a slot in the handle 16. Upon engagement of the cone 15 with the tube end 20 the rod 14 remains axially stationary relative to the sleeve 12 so that the spring 19 is compressed and the cone 15 rotates without moving axially until a face 12f of the sleeve 12 abuts a shoulder 15b of the cone 15. Thereafter the cone 15 moves forward and rotates with the sleeve 12 to flare the tube end either against a frusto-conical surface 13a of the clamp 13 or in the air. Reverse rotation of the handle 16 then rotates the cone 15 and moves the sleeve 12 back, the spring 19 keeping the cone 15 in contact with the now flared tube end to burnish it, until a sleeve shoulder 12e abuts a hub 16a of the handle 16 to lift the rod 14 and thus the cone 15 away from the flared tube end. In a modification, Fig. 5, a rod 114 carrying a flaring cone 115 has a square-sectioned extension 114b slidable in a square-bore 112g of a sleeve 112 and in a square bore of a handle 116 resting on the sleeve 112. A screw 116c extending through the handle 116 is secured adjustably to the extension 114b so that relative axial movement of the cone 115 and sleeve 112, and thus the amount of cone rotation in contact with a flared tube end, may be adjusted.

Patent GB-486170-A (GB)
Title: An improved method of desulphurising motor fuels
IPC: C10G17/06
Filed: 1937-06-19
Abstract: Hydrocarbons of motor fuel boiling range are freed from all sulphur compounds by separating into high and low boiling fractions, treating the high boiling fraction with diluted sulphuric acid, and the low boiling fraction with concentrated sulphuric acid, and treating the recombined fractions with hot caustic alkali under pressure. Alternatively, the hydrocarbons may first be submitted to the alkali treatment, then treated with diluted sulphuric acid, the low boiling fraction separated, and, after treatment with concentrated sulphuric, recombined with the remainder of the hydrocarbons.  The temperature separating low from high boiling fractions is about 90 DEG  C. Concentrated sulphuric acid is about 66 DEG  B<\>ae, and diluted sulphuric acid is any concentration less than this.  Cracked benzine, motor benzol or distillation benzine is separated into two fractions boiling up to 90 DEG  C. and from 90 to 180 DEG  C.  The low boiling fraction is freed from thiophene by extraction with 66 DEG  B<\>ae sulphuric acid, and the high boiling fraction is washed with 60 DEG B<\>ae sulphuric acid.  The fractions are then combined and heated under pressure with caustic soda, whereby carbon disulphide is removed.  The valuable olefines are retained in the fuel. Specification 414,644 is referred to.

Title: Improvements in the manufacture of fuseheads for electrical firing
IPC: A63B27/02
Filed: 1927-06-29
Abstract: 297,869. Littlebury, W. O., and Imperial Chemical Industries, Ltd. June 29, 1927. Explosives.-Basic dinitrosalycilates of lead are used in electrically fired fuze heads, for example of the kind described in Specification 201.220. Such basic salts are manufactured by the interaction of an alkaline solution of sodium or like dinitrosalycilate with a soluble lead salt such as lead nitrate. These salts may also be co-precipitated with other basic lead salts by the addition of an alkaline solution of an alkali salt of another nitrocompound, for example trinitroresorcinol or trinitrophenol, to the dinitrosalycilate solution before the double decomposition by the soluble lead salt. The salts are made into a paste with the usual collodion employed in fuze head manufacture, in which, however, the cellulose may be wholly or partly replaced by shellac; and the paste applied to the usual thin wire bridge.

Patent GB-1003815-A (GB)
Title: Manufacture of acid solutions
IPC: C01B21/086
Filed: 1964-04-27
Abstract: A sulphuric acid solution of nitrosyl sulphuric acid and/or its anhydride is prepared by reacting, at a temperature in the range 10 DEG  to 105 DEG  C., nitric acid, sulphur in an amount of at least 0.33 g. atom per g. mol. of nitric acid and oleum containing 0.16 to 1.16 mol. of sulphur trioxide per mol. of nitric acid and at least sufficient sulphuric acid, i.e. not less than 0.8 mol. per mol. nitric acid, to dissolve the nitrosyl sulphuric acid and/or anhydride.  The oleum suitably has a sulphur trioxide concentration of not more than 60% by weight.  The amount of sulphur, suitably 10-200 Tyler mesh particle size, is preferably not less than 10% in excess of the theoretical requirement.  The nitric acid is preferably 98-99% and sufficient SO3 must also be introduced to react with the additional water.  The reaction may take place by introducing the nitric acid and oleum into an agitated reactor, which may have a gas outlet pipe, and charging the sulphur subsequently.  The reaction temperature may be controlled by adjusting the rate of feed of sulphur or by extraneous cooling.  Excess sulphur is removed by filtration of the hot reaction product.  Alternatively, the sulphur may be suspended in an inert liquid, suitably part of the product of a previous operation, in a reactor communicating with a scrubbing tower through which the oleum and nitric acid are fed.  Oxides of nitrogen formed when high reaction temperatures are employed are thus returned to the reaction vessel after counter-current contact with the descending liquids.
