Title: Improvements relating to mesh screens for use in television or like transmitting tubes
IPC: H01J29/43
Filed: 1936-01-27
Abstract: 471,109. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 27, 1936, No. 2585. Convention date, Jan. 30, 1935. [Class 39 (i)] Mosaic electrodes such as double - sided photo-electric screens of cathode-ray tubes for television transmission are formed by coating a grid 12, Fig. 7, at least on its upper side, with electrically insulating material 16, distributing conductive elements 46 of area greater than the grid apertures 22 over the upper side as from a sieve 42, Fig. 5, and creating, as by a fan 38 in a chimney 36, a lower fluid pressure below the grid than above it. One element 46 is thus drawn into each aperture 22 and held there whilst surplus elements are brushed off. A binder is then applied to the upper side of the grid and the grid is baked to drive off the binder and soften the insulation 16 so that the elements 46 become partly embedded therein as shown in Fig. 7. The elements 46 may be silver spheres formed by spraying the metal into the air and are finally coated with photo-electric material on their upper surfaces. The grid apertures are open at their lower ends to expose the elements 46 to the scanning cathode-ray. The grid 12 is a flattened wire mesh or perforated plate. The mosaic is provided with a separate grid 30b .and mounted and used as described in Specification 471,137 In a modification, the grid 12 is coated only on its upper side so that its uncoated lower face serves as the grid 30b.

Title: An improved method of and means for cleaning the discs of centrifugal separator bowls
IPC: B04B15/06
Filed: 1930-01-27
Abstract: 332,185. Aktiebolaget Separator. Jan. 26, 1929, [Convention date]. Cleaning separator discs.-The liner discs of a centrifugal separator are cleaned by a flow of liquid which only passes through part of the spaces between the discs at any one instant. With the arrangement shown in Fig. 1, the ordinary feed pipe is removed and the pipe 2 for the conveyance of the washing fluid is inserted in the central space of the discs. This pipe 2 has small apertures 3, in order that the liquid can only enter a few of the spaces between the discs, so that the velocity of the fluid is high. The tube is axially movable. In a modification the tube has narrow vertical openings so that the liquid passes over a portion of each disc. In the form shown in Fig. 2, an annular tube 5 supplies washing fluid through the slot 6 at the periphery of the discs, and this is discharged through the ordinary discharge channels 7. In a further modification, the washing fluid is supplied to a hood 8, Fig. 3, from whence it flows to the pile of discs through the channels 7. A cylinder 10 with annular openings 11 confines the flow to a few spaces. In another modification, the fluid is supplied at the periphery of the discs to one or more of the sectors formed by the spacing ribs of the discs.

Patent GB-683632-A (GB)
Title: Improvements in or relating to the production of antibiotic substances
IPC: C07H15/232
Filed: 1950-02-03
Abstract: An antibiotic neomycin is obtained from a culture of a neomycin-producing strain of Streptomyces fradiae, e.g. an isolate known as S. fradiae 3535.  Neomycin is thermostable; soluble in water, dilute HCl and acid-alcohol; insoluble in ether, acetone and chloroform; non-toxic to animals; stable in aqueous solution for at least a month; yields a negative reaction to tests for guanidine; has substantial antibiotic activity against B. subtilis, B. mycoides, B. cereus, S. marcescens and Bodenheimers organism and against both streptomycin - sensitive and streptomycin - resistant strains of E. coli, S. aureus, M. tuberculosis and M. avium; and is inactive against fungi.  The micro-organism is cultivated in a medium containing a peptone or protein digest, e.g. soybean peptone, an extractive nutrient such as meat or yeast extract, a carbohydrate such as glucose or maltose, sodium chloride, water and, if not already present in the water, a zinc salt especially sulphate.  The pH of the medium is adjusted to pH 7 to 7.2 by means of sodium hydroxide, and may be maintained by the addition of sodium carbonate or calcium carbonate.  The inoculated medium is incubated at 22 DEG to 28 DEG  C. for 7 to 12 days in the case of a stationary culture, agar being added to the culture medium to maintain the organism growth at the surface.  Whereas incubation of 3 to 5 days at 22 DEG to 28 DEG  C., preferably 25 DEG  C., is used for shaken cultures, which contain agar incorporated to reduce air diffusion.  An example is given in which neomycin is separated from a culture thereof by filtering off the solids, acidifying the culture broth to pH 2.0-2.5 with hydrochloric acid, stirring with activated charcoal to absorb impurities and filtering with the use of a filter aid such as fuller's earth.  The pH of the filtrate is adjusted to pH 7.1 \sB 0.2 and the neomycin absorbed on a zeolite from which it is removed by elution with 10 per cent aqueous ammonium chloride. The eluate is adjusted to pH 7 and treated with activated charcoal.  The neomycin is eluted therefrom with 0.05 N. hydrochloric acid in 50 per cent methanol, the eluate adjusted to pH 6.0-7.0 and concentrated in vacuo.  Methanol is added to the concentrate and the precipitated impurities filtered off.  This purification was repeated and the neomycin finally precipitated by the addition of 8 to 10 volumes of acetone.

Title: Clockwork fuse for projectiles
IPC: F42C9/02
Filed: 1927-02-02
Abstract: 265,588. Hrncir, J. Feb. 2, 1926, [Convention date]. Projectile fuzes.-Clockwork fuzes are driven by centrifugal racks and controlled by centrifugal pendulum escapements; and the setting is spread over several revolutions by means of a helical scale in conjunction with a spiral groove for releasing a spring striker cocked by inertia on discharge. As shown, two racks p1, P2, Fig. 1, move outwards in opposite directions by centrifugal force and drive a set of gear wheels controlled by two centrifugal pendulums y, Fig. 3, each in conjunction with an anchor T and an escapement wheel r2. A disc K2 rotated by this clockwork has a spiral groove F engaged by a projection M on a trigger Z, which is thus moved radially outwards until, at the appointed time, it escapes from the spiral groove and releases a spring striker n, u. The initial position of the trigger Z in relation to the spiral groove determines the time of the fuze and is adjusted by means of a head h, which, when rotated, carries the trigger round with it. This setting is indicated by a pointer i, which is moved longitudinallv to follow a helical scale on the drum v rotating with the head h. The spring of the striker is cocked at the moment of discharge by two pairs of segments s1, s2 which set back by inertia, and are then caught in recesses L.
