Title: Process for biosynthesis and purification of streptomycin or other antibiotic
Filed: 1965-03-03
Abstract: Streptomycin or other antibiotic capable of being adsorbed on an ion exchange resin is produced by cultivating the appropriate antibiotic-producing micro-organism in a medium free from calcium and magnesium ions but otherwise containing conventional nutrients and, prior to inoculation with the producing micro-organism, an ion exchange resin capable of adsorbing the antibiotic is introduced into the culture medium and, after the end of the fermentation, the ion exchange resin is separated from the culture medium, washed and the antibiotic eluted therefrom.  The example relates to the preparation of streptomycin by the cultivation of Streptomyces griseus in the presence of Amberlite IRC 50 at pH 6.8.  At the end of the fermentation, the resin is separated, washed with deionized water and eluted with H2SO4 at pH 0.5-1.4.  It is further purified by treatment with activated charcoal and sulpho-cationic resins.

Abstract: 701,428. Fusible cut-outs. CHASESHAWMUT CO. April 10, 1952, No. 9269/52. Class 38 (1) In a high-rupturing- capacity fuse, Fig. 2, a flat fuse link 26 comprising a pair of wide portions 36, Fig. 5, joined by a pair of very narrow necks 34, is gripped at its ends in slots in a pair of spaced terminal members 14, 16 forming closures for the ends of a tubular insulating casing 18. The link is sandwiched between a pair of insulating plates 44 and mica sheets 46 having vents 50, Fig. 3, located opposite the necks 34 and sealed by discs 52 which, when the pressure built up by fusing of the necks exceeds a predetermined value, release the arc products suddenly into pulverulent cooling material 48 surrounding the plates 44. Insulating discs 54 are interposed between the material 48 and the terminals 14, 16. Two links as above may be enclosed in separate chambers in a common casing and connected in series, Fig. 6 (not shown). Fig. 8 shows a modification wherein the link 26<SP>1</SP> is tubular with a pair of diametrically-opposite necks 34<SP>1</SP>. The link is located between a central insulating cylinder 45 and a surrounding insulating tube 45<SP>1</SP> provided with diametricallyopposite vents. It is stated that the insulating members thermally insulate the cooling material 48 thereby increasing its arc-quenching efficiency by keeping it cool, and that the construction of the link as shown results in a reduction of the maximum short-circuit current taken by the fuse for a given current-carrying capacity. It is also stated that by increasing the width of the wide portions in Fig. 5 an increase in current-carrying capacity is obtained up to a critical ratio of the cross-section of the wide portions to the cross-section of the necks, above which a further increase in width does not increase the current-carrying capacity. Preferably the ratio should be within the range 15 1-50 : : 1.

Filed: 1923-04-05
Abstract: 195,977. Dick Co., A. B., (Assignees of Hill, E. W.). April 7, 1922, [Convention date]. Stencils.-A stencil sheet, of the kind. in which characters are formed thereon by impact with type or by means of a hand stylus, is prepared from a sheet of Yoshino or like paper impregnated or coated with a medium which includes a cellulose ester such as cellulose nitrate or acetate: Pyroxylin enamel " is preferably used, this being a solution of cellulose nitrate to which a pigment such as zinc oxide has been added. A tempering- agent may also be .added to prevent the enamel drying too hard, this agent consisting of caster oil or a similar oil in which the cellulose, ester is soluble, together with soya bean oil nr other oil in which it is not soluble, this latter expediting the setting of the medium. Colcuring-matter such as a dye or carbon black dissolved or suspended in amyl-acetate may be added to the tempering- agent. The sheet may be coated by drawing one side of it over the surface of the solution and draining off the excess by drawing it over a wire or straight edge. If the coating is too sticky, powdered soap-stone may be dusted over the sheet or it may be laid between sheets of absorbent paper. The Specification, as open to inspection under Sect. 91 (3) (a) states also that, in forming the stencil, the coated sheet may be superimposed on a flexible. backing of a colour or ehade contrasting with the sheet so that, as the characters are formed in the sheet, they may be easily read. Also the coating solution may be produced in an opaque flat white or in a light tone such as gray or light tan, and a single or double-faced carbon sheet, or two single-faced sheets back to back, may be interposed between the coated sheet and the backing, whereby a copy of the characters may appear on the stencil or on both the stencil and the backing. This subject-matter does not appear in the Specification as accepted.

Filed: 1953-04-07
Abstract: 725,594. Helicopters. THOMSON, A. C. April 7, 1953, No. 9444/53. Class 4. A helicopter includes a fuselage and jet-driven rotor, means fixed to said fuselage for applying a turning moment to said helicopter, means for deriving a turning effort therefor from rotation of said rotor, mechanism for reversing the direction of the turning moment while said rotor rotates in the same direction, a hollow post on said fuselage supporting a hub on which the inner ends of the rotor blades are mounted, a bearing between said post and said hub in alignment with the inner ends of the blades, a steering control carried by'said hub, and a control rod for said steering control and having a universal connection in said post concentric with said bearing. In the embodiment described, the rotor hub 13 supporting the blades 3 and 4, which are jet driven, is freely tiltable with respect to a shaft 19 fast to the helicopter. The hub also carries a lower bevel gear 45. Within the shaft 19 is a control rod 23, slidable axially and jointed to shaft 40 by a universal joint centred near the centre of tilting of the hub 13. Fast to the shaft 40 is an upper bevel gear 48. Meshing with the upper and lower bevels are two pinions 51, retained by a spider 27, and mounting rotatably two arms 10, 11 on which are mounted blades shown at 8 in the low drag position and at 61 in the high drag position. Shaft 40 also distributes fuel to the rotor jets by a rotary seal, and ignition current through a slip ring. In operation, if the helicopter is stationary, the blades 8 must rotate at half the rotor speed, If the pilot moves control rod 23 axially, the collars 56, 57 move the arms 58, 59 to alter the pitch of the blades 8, increasing or decreasing their drag. This drag is transmitted through the bevel gearing 51, 48 to the helicopter, and causes a rotation in either direction as the drag is increased or decreased. The control rod 23 is preferably operated by rudder pedals (see Fig. 1, not shown). In a modification (Fig. 8), the arms 58, 59 rotate a shaft 110 in the blades 106, which splits open the leading edge of the blade to increase the drag.
