Title: Purification of streptomycin
IPC: C07H15/238
Filed: 1949-04-20
Abstract: Streptomycin substantially free from histamine is obtained from aqueous solutions thereof e.g. culture broth, by percolating said aqueous solutions through a static bed or column of a water-insoluble polycarboxylic acid ester of a carbohydrate and fractionally eluting the histamine and streptomycin therefrom with an aqueous eluting solution.  The eluting solutions are dilute aqueous acid solutions having a pH less than 2.5, such as hydrochloric acid, sulphuric acid and phosphoric acid; and aqueous solutions of alkaline earth metal salts such as magnesium sulphate, or aluminium salts.  The preferred water-insoluble esters are those of the dicarboxylic acids with water-insoluble carbohydrates such as cotton wool; especially the acid succinic, phthalic or maleic esters of cellulose.  Maximum esterification is desirable provided the product produced is insoluble in water or in aqueous alkaline solutions.  The ester may be used in the acid form or in the form of a salt, especially an alkali metal salt such as the sodium salt, which is preferred.  In the preferred process the streptomycin solution is adjusted to a pH greater than 4, preferably between 4 and 8, passed through a column of the polycarboxylic acid ester, the column washed with water or other solvent, dried by washing with an organic solvent such as acetone and the streptomycin and histamine removed selectively with the same eluting agent.  The process may be applied to the purification of other basic antibiotics such as streptomycin. Specification 638,664 is referred to.

Title: Carding machine
IPC: D01G31/00
Filed: 1978-03-16
Abstract: A device for bringing together a running fibre fleece delivered by a pair of cooperating rollers (5, 6) forms a part of a fleece-forming apparatus which itself follows a card. Guiding elements (8d, 8d') are arranged in the region directly adjacent to the rollers (5, 6). The hollow guiding surface of the guiding elements (8d, 8d') extends transversely to the direction of movement of the fibre fleece issuing from the rollers (5, 6) and partially envelopes the two rollers (5, 6). The guiding element can be in two parts (8d, 8d') and be connected to a device (14, 30, 31) which allows it to pivot about a vertical axis. This arrangement results, without the use of movable parts, such as rolls, bands, etc., in a simple guiding surface which can be produced economically and which allows positive guidance and simultaneous stabilisation of the fibre fleece, with the fibre orientation being maintained at the same time. <IMAGE>

Title: Improvements relating to hydraulic systems
Inventor: FUELL FREDERICK JAMES
IPC: G05B19/46
Filed: 1964-03-13
Abstract: 1,105,655. Advancing mine roof supports. FAIREY ENGINEERING Ltd. March 12, 1965 [March 13, 1964], No. 10783/64. Heading F1P. A hydraulic system, for operating a self advancing mine roof support having two legs or groups of legs connected by a horizontal hydraulic ram, comprises two sequence controllers, each arranged first to lower one of the legs or groups of legs, then to extend or contract the horizontal ram, then to raise the leg or group of legs. The two sequence controllers operate in succession, and a reversing device is provided so that in the first sequence the horizontal ram is extended, and in the second sequence it is contracted. Hence the order in which the controllers operate determines whether the support advances or retreats. As shown, the piston of the horizontal ram 16 is connected to one group 11, 12 of legs, and the cylinder to another group 13, 14. The legs 11, 12 are connected to a pressure supply 72 through a poppet valve 25, and may be lowered by opening individual valves 21, 22 connected to the fluid return pipe 75. The legs 13, 14 have similar connections to valves 31, 32, 35. These valves are operated by cams on piston rods of rams 41, 42, through tappets 47, and the rams are supplied with fluid through a restriction 71 and solenoid change-over valves 68, 69. These valves also supply fluid to opposite ends of a reversing valve 70, the position of which depends on which valve 68, 69 is operated first. The inoperative valve allows fluid to escape to the return pipe 75, but when the second valve is operated there is no change in the position of the reversing valve because the end pressures are the same. A friction device may be used to prevent any such movement. The reversing valve 70 supplies fluid to the horizontal ram 16 from 24 or 33 and returns it to valves 23 or 34. The valves 24, 34 are operated together by the sequence ram 41, and the valves 23, 33 by the ram 42. This joint operation is effected by common shafts 53, instead of individual shafts 52, each operated by a single tappet 47. Thus when the rams 41, 42 operate in sequence, fluid is supplied first to one side of the horizontal ram 16, then to the other. To move the support in one direction the valves 68 is operated, the valves 21, 22, 24 and 34 and 25 operate in sequence, and then microswitches 63 are operated to operate the valve 69, and hence the ram 42. The microswitches 62, 63 are biased by a fluid-pressure piston 67 to a position in which they can be contacted by the rams 41, 42. Hence, if there is a sufficient pressure reduction in the first half of the cycle, the second half is not initiated. The tappet shafts 52, 53 project through the casing of the system so that they may be rotated manually. The invention may also be applied to the control of machine tools.

Abstract: 1491416 Travelling wave-tubes VARIAN ASSOCIATES Inc 17 March 1976 [20 March 1975] 10817/76 Heading H1D In an interdigitated slow-wave structure in which the fingers extend from a pair of straps 12 and a conductive back wall 13 is spaced from the opposite side of the set of fingers to that adjacent the electron stream 11, the fingers are connected to wall 13 by conductive vanes 17 which each extend from one end of a finger part way only along the length of the finger, whereby thermal dissipation is improved without too serious a reduction of interaction impedance. In the embodiment shown the vanes extend from the strap-supported ends of the fingers, but they may instead extend from the free ends (Figs. 5 and 6, not shown) leaving a gap between the vane and the finger-supporting strap. Reference is made to the possibility of the vanes being apertured, and of a thickness different from that of the fingers. As described, the slow-wave structure is employed in a linear crossed-field amplifier, Fig. 7, in which the slow-wave structure 10 faces a linear thermionic or secondary electron emissive cathode 34 having edge focus electrode portions 37a and 37b, and the envelope includes upper and lower ferromagnetic plates 31a and 31b coupled to magnet 38, and cooling fins 39.
