Title: Improvements in or relating to electron discharge apparatus
IPC: H01J25/12
Filed: 1940-07-05
Abstract: 542,390. Electron-oscillators. STANDARD TELEPHONES & CABLES, Ltd., and MOTZ, H. July 5, 1940, No. 11306. [Class 39 (i)] In electron velocity modulation apparatus such as described in Specifications 516,750, 518,015 and 537,490, the electron beam is produced in a gaseous atmosphere which is ionized by electronic impact or by contact with a hot surface having a work function which is larger than the ionization potential of the gas to be ionized. As shown a velocity-modulation device comprises two toroidal resonators R, Rl, with a back coupling L1, and gaps G through which passes a beam of electrons generated by a cathode K and focusing electrode system. A mass B of barium or barium berylliate or other compounds in a container C is vapourized by a heater H, and the vapour is ionized by contact with hot wires W of oxidized tungsten &c., and the ions are formed into a beam by a focusing electrode system Fl, directed towards the cathode. Caesium may be used instead of barium. Alternatively a drop of mercury may be introduced into the evacuated envelope so as to obtain a pressure of 10<SP>-5</SP>-10<SP>-3</SP> mm. of mercury under operating conditions. Specification 542,389 also is referred to.

Title: New colouration process for textile materials
Inventor: ALSBERG FREDERICK RICHARD
IPC: D06P5/12
Filed: 1957-04-10
Abstract: Resist prints on textile materials are obtained by locally applying a resist paste containing an organic amino compound and a thickening agent and then padding with a solution of a reactive dyestuff.  In the case of natural or regenerated cellulose textiles an alkaline compound, e.g., sodium carbonate, or a compound, e.g. sodium bicarbonate, which on heating or steaming gives rise to an alkaline compound, is also applied before, after or together with the dyestuff.  Specified amino compounds are monoamines such as diethylamine, diamines such as ethylene diamine, polyamines such as diethylene triamine, triethylene tetramine or tetraethylene pentamine, acid amides such as formamide or dimethylformamide, amino-alcohols such as mono-, di- and tri-ethanolamine and b -diethylaminoethanol, cyclic amino compounds such as hexamethylene tetramine and polyvinyl pyrrolidone and amino-acids such as glycine, benzyl glycine, phenyl glycine, phenylglycine-o-carboxylic acid, methyltaurine, N-methyl-, N-ethyl- and N-benzyl-anthranilic acid, N-benzylsulphoanthranilic acid, 2-ethyl-amino-5-sulphobenzoic acid and especially sarcosine, and salts of such acids.  A suitable thickening agent is British gum thickening.  Specified reactive dyestuffs are nitro, azo, anthraquinone and phthalocyanine dyes containing, as reactive groups, mono- or di-chlorinated or -brominated s-triazinyl or pyrimidyl radicals, or b -halogenopropionyl, b  - halogenoethylsulphonyl, b -halogenoethylsulphamyl, b  - sulphatoethylsulphonyl, b  - hydroxyethylsulphonyl, chloracetylamino, b  - (chloromethyl) - b  - sulphatoethylsulphamyl, alkyl phosphite, sulphonethyleneimide and sulphon-fluoride radicals.  The process is applicable to textile materials of cotton, viscose rayon, silk, wool and nylon, and a vat dyestuff resist may also be printed alongside.  In Example 8, the dyestuff employed is prepared by treating the sodium salt of copper phthalocyanine - tetra - 4 - sulphonic acid with chlorosulphonic acid, precipitating the sulphonchloride and treating it with 2-chloroethylamine hydrochloride in aqueous sodium bicarbonate, when the sulphonchloride groups are partly replaced by sulphon-b -chloroethylamide groups and partly hydrolysed to sulphonic acid groups.

Title: A process for preparing the antibiotic cycloheximide and its isomer by fermentation
IPC: C07D211/88
Filed: 1959-04-09
Abstract: <PICT:0887825/IV (b)/1> Cycloheximide and an isomer thereof, herein designated naramycin A p  and B, respectively, are produced by the aerobic cultivation of a cycloheximide-producing strain of Streptomyces naraensis (Nov. Specification), especially S. naraensis ATCC 13788, in an aqueous nutrient medium containing carbohydrates, nitrogen compounds and mineral salts.  A temperature of 24 DEG C. to 30 DEG C. and duration of cultivation of 2 to 7 days is used.  The medium used in the example consists of glucose, starch, soyabean, sodium chloride, wheat-gluten cake and water and the pH was adjusted to 7.0.  The cycloheximide is isolated by (a) solvent extraction or (b) adsorption.  The extraction is by means of a water-immiscible solvent such as alkyl acetates wherein the alkyl has 2 to 5 carbon atoms, mono alcohols having 3 to 5 carbon atoms and chlorinated hydrocarbons of 1 to 5 carbon atoms.  In the example, the classified broth is adjusted to pH 5.5, adsorbed on activated carbon, eluted therefrom with methanol acidified with hydrochloric acid to pH 2.0. The methanol removed from the eluate with the introduction of water and the aqueous residue extracted with ethyl acetate.  After removal of the ethyl acetate, the crude is dissolved in isoamyl acetate and cycloheximide crystallised therefrom.  The mother liquor is concentrated to remove the solvent, the residue dissolved in benzene, passed down a column of activated alumina, eluted with benzene containing 3% methanol, concentrated and ether added to precipitate the isomer of cycloheximide (naramycin B) which has the infra-red adsorption spectrum shown in the Figure.  Specification 639,943 is referred to.

Title: Particulate material separator
IPC: B22D29/00
Filed: 1960-04-05
Abstract: 903,831. Pneumatic separation. BELL INTERCONTINENTAL CORPORATION. April 5, 1960 [Aug. 4, 1959], No. 11968/60. Class 117. Dust is removed from abrasive granules &c. in a machine having a hopper 14, fed by a spout 15 with the mixed material, and a feed control disc 18 located below the hopper outlet. The hopper and disc are suspended by a rod 20 connected to a rocker arm 22 fulcrumed at 24 and held by tension springs 26, 28 ; in the non- operative position the hopper and disc are urged upwardly and the material is prevented from spilling over the edge of the disc by a vertically adjustable collar 17 around an opening in the machine casing. When a sufficient quantity of material accumulates in the hopper, the assembly moves downwardly against the action of the springs and material flows over the edge of the disc and then over the edge of a plate 32 having a vertical sleeve portion 30. Material thus flows across a gap between the plate and the rim 40 of a cylindrical housing 34 provided with a hopper 36 and spout 38. An air intake pot 45, open at its top, is connected by a duct 46 to the inlet of a fan 50, and the fan outlet is connected to the machine casing. With the fan in operation air is directed around the casing above a canopy 42 and then passes inwardly and down into the said gap whereby dust is carried away from the main stream which falls to a hopper 68. The air and dust stream flows first downwardly through an annular passageway between the housing 34 and a baffle 39 and then upwardly to the top of the pot 45 ; the heavier particles in the stream fall to the hopper 36 and spout 38. A dust control valve 48 may be mechanically connected to the rod 20 so that the rate of air flow through the system automatically varies in proportion to the flow of material through the machine. Instead of a closed circuit system the duct 46 may lead to a dust collector, and an air inlet may be provided in the machine casing.
