Title: Method and apparatus for casting directionally solidified discs and the like
IPC: C30B11/00
Filed: 1970-03-09
Abstract: 1,264,053. Zone melting. UNITED AIRCRAFT CORP. 9 March, 1970 [13 March, 1969], No. 11115/70. Heading B1S. [Also in Division B3] Apparatus for casting an article with a selected grain orientation comprises a chill plate 10, a mould 12 having an extension 14 opening onto the chill plate, and heating means 22, 24, 26, 28 and 30 arranged so as to provide a lateral thermal gradient from the downward extension to the parts of the mould laterally remote therefrom. After pouring the metal into the mould, coolant is supplied to the chill plate 10 to cause formation of vertically orientated directionally solidified grains in the extension 14. When solidification reaches the position represented by line 34, a radial thermal gradient is produced in the disc portion of the mould by gradually reducing the heating effect from the axis outwardly toward the periphery of the disc. This causes grain growth in a radial direction and produces a [0,1,0] radial orientation and a [1,0,0] tangential orientation. A seed (36) made up of wedges (38) each having the desired orientation for the portion of the disc extending outwardly therefrom may be provided at the bottom of the extension 14. In an embodiment, Fig. 6, the mould is made up of individual mould elements 50 extending radially outward from a central cavity 52 surrounding a vertical cylindrical chill 54. The chill is surrounded by seed segments 56, one for each mould element 50. A radial orientation of the grains is obtained throughout the mould. The alloy is poured at a temperature at least 100‹C above its melting point.

Title: A new antibiotic, and a process for the production thereof
Filed: 1952-05-06
Abstract: An antibiotic P.A.86, which is strongly antifungal but possesses little activity against bacteria, is produced by cultivating a strain of Streptomyces rimosus, which is described, in an aqueous nutrient-containing medium under aerobic conditions. Submerged aerobic fermentation is preferred, at a temperature of 25-30 DEG  C., especially 28 DEG  C., for 2 to 7 days, the initial pH being 7.0. Specified nutrients are starch, sucrose, glucose, soybean meal, lactalbumin, protein, e.g. casein hydrolysates or digests, distillers' solubles, yeast extracts, salts such as sodium chloride, phosphates and sodium nitrate, and buffers such as calcium carbonate. Antifoaming agents are silicones, lard oil and soybean oil.  P.A. 86 is isolated by solvent extraction. After removing the mycelium at an acid pH, the broth is adjusted to a neutral or slightly basic pH and extracted with butanol.  The extract is evaporated to small volume in the presence of water, and P.A.86 crystallizes from the dry butanol. It is recrystallized from 50 per cent aqueous acetone, or by adding water to a methanol solution.  In place of butanol, other substantially water-immiscible solvents, e.g. amyl alcohol and benzyl alcohol may be used.  P.A.86 is a crystalline antibiotic containing C=60.3 per cent, H=8.3 per cent, N-3.41 per cent and O=27.99 per cent.  It is soluble in mixtures of alcohol-water, relatively insoluble in water, alcohols, ketones and ether. Maximum absorption in the ultra-violet region is shown at 279,291, 304 and 318 millimicrons.  The infra-red absorption spectrum is characteristic. Other strains of Streptomyces rimosus produce oxytetracycline (Terramycin) as shown in Specification 684,417, and antibiotic P.A.85, as shown in Specification 718,021.

Title: Improved method of producing a substantially spherical or substantially cylindrical surface of large radius
Inventor: CROOK ALFRED WILLIAM
IPC: B23P25/00
Filed: 1956-04-16
Abstract: 854,521. Milling; planing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 9, 1957 [April 16, 1956], No. 11510/56. Class 83 (3). A method of producing a surface of substantially circular cross-section on a member A, comprises supporting the member on spaced abutments a, a<1>, b, b<1>, applying force to the member at a region located symmetrically with respect to the abutments and on the opposite face of the member from that engaged by the abutments, so that the member is deflected into a convex or concave shape, machining the curved face of the member into a plane surface e, and then removing the deflecting force to restore the member to an unstressed condition and allow the machined surface to acquire the desired shape. For producing a substantially cylindrical or spherical convex surface, a single or, as illustrated, a double row of abutments a, a<1>, b, bl is provided which, in the case of a spherical surface, follows a circular path, the deflecting force being applied by bolts f. In the case of a spherical surface, central pressure is applied by one or more bolts, or by an eye-bolt screwed or welded to the underface of the member and stressed by a hook bolted to a bedplate. For producing concave surfaces, abutments in the form of clamps restrain outward movement of the periphery of the member while it is deformed, as by a screw-jack, into convex form. The convex surface is then machined into a plane surface and the deforming force released to allow the machined surface to assume a concave form. Alternatively, the central portion of the member is supported on one or more abutments, and the deforming force applied to the periphery by bolts. Instead of clamping the members to the bed of a machine to produce the deforming force, one member may be clamped to another with interposition between them of the abutments, the members thus being deformed in pairs. If the deforming force stresses the member beyond its elastic limit, so that its initially plane unmachined undersurface does not return to plane form, the member is bolted against the plane surface of a backing to restore the undersurface to plane form.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/68
Filed: 1920-04-27
Abstract: 166,375. Automatic Telephone Manufacturing Co., Ltd., and Gillings, C. April 27, 1920. Automatic exchange systems.-In systems in which each subscriber has a non-numerical line switch, a fixed group of trunks, equal in number to the positions of the line switches, is made accessible to a computed number of subscribers, thus enabling a more accurate adjustment of the traffic to be made than in the customary arrangement, in which a fixed group of subscribers is given access to a computed number of trunks. For example, in the system illustrated, in which 200 subscribers are each equipped with a line switch having 25 positions, computation may show that the first group of 25 selectors A can handle the traffic of subscribers 1 to 91, and that the second group of 25 selectors B can handle the traffic of subscribers 92 to 194, the residue being dealt with by a few additional selectors C. The line switches are arranged in eight sets of 25, all the corresponding terminals in each set being multipled to groups of trunks D .. G and L ..O, there being 25 trunks in each group corresponding to the 25 positions of each switch. The trunks D, E, F are all multipled together and to the selectors B at K, but of the trunks G, 16 are multipled to selectors A and 9 to selectors B, and of the trunks O, 19 are multipled to selectors B and 6 to selectors C. Thus 16 out of 25 calls through the fourth group of line switches go to selectors A, the other- 9 going to selectors B; and 19 out of 25 calls through the eighth group of line switches go to selectors B, the other 6 going to selectors C; so that in effect, though not literally, the selectors A serve the first 91 subscribers and the selectors B serve the next 103 subscribers. The invention consists particularly in this method of dividing- the calling lines into groups of irregular size while keeping the line switches in sets of a standard number.

Title: Improvements in and relating to Coating methods and apparatus
Inventor: JONES SAMUEL HAYDN
IPC: B05D1/32
Filed: 1965-03-18
Abstract: 1,155,011. Coating apparatus. BADA LEX (ASHDOWN) Ltd. 20 June, 1966 [18 March, 1965], No. 11622/65. Heading B2L. Apparatus for coating an article 10 with powdered coating material comprises a holder for the article, said holder having first and second separable parts 45, 48, means for moving said parts relatively to engage and retain .said articles 10, a container 68 for powdered coating material, means for feeding gas to said container for fluidising powdered material in said container and means for immersing the held article in the fluidised coating material. The lower part 45 and the upper part 48 may be interconnected by a shroud 52 to prevent coating the outer peripheral surface of article 10, the space formed by the shroud being connecting to a compressed air supply to prevent ingress of coating material. Porous resilient rings 47, 50 are interposed between the article and the clamping parts. The invention is particularly applicable to coating parts only of articles having an opening extending between opposed outer surfaces e.g. electrical stators and if the inner peripheral surface is not required to be coated inner inflatable masking means may be inserted in the opening as shown at 65, 66. Preferebaly the part 45 is carried by a cradle 53, 54 carried from slides 55, 56 which ride on guide pillars 57, 58 the slides being biased upwards by springs 60, 61 and the part 48 is carried by a support frame 62 from the ram 63 of a pneumatic actuator. In operation the actuator is openated to withdraw ram 63 thus separating the masking sections 45, 48 and allowing a stator to be inserted in the lower part 45. The actuator is then operated to lower the ram 63 causing the upper part 48 to engage with the top surface of the stator and at the same time the central masking section to enter the tunnel of the stator. Air is admitted through conduit 67 (to inflate the internal mask and if desired purging air can be admitted through inlet 73 to the chamber formed by shroud 52. Continued movement of the ram causes the stator with the masking means firmly in position to be moved downwardly into the fluidised material 69 within tank 68. In another embodiment the lower part 45 is fixed and arrangements are provided to lift the coating material container. In this case the container is a flexible tube such that on raising it the coating material is forced to circulate up and around the stator to be coated. In another embodiment provision is made to invert the stator so as to coat the stator in two half dippings to ensure a more even coating.
