Abstract: 645,146. Pulverizing-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 4, 1947, No. 32076. Convention date, Dec. 4, 1946. [Class 59] Apparatus for pulverizing solid materials by the action of metallic particles thereon, having a chamber for treating the material, a striking surface positioned within the chamber, and means for separating the pulverized material from the metallic particles and removing it from the chamber after the action of the metallic particles thereon, has provided artificial accelerating means for forcibly projecting a stream of the metallic particles against the striking surface, the material to be pulverized being introduced separately into the chamber by magazine supply means at a position spaced between the accelerating means and the striking surface, the metallic particles being returned to the accelerating means after separation of the pulverized material therefrom. In one embodiment, Fig. 1, a rotary vaned impeller 9 throws steel shot against an annular striking surface 12, the shot then falling through openings 14 in a plate 13 to a hopper 11 whence it is returned by rotary feed means 10 to the impeller. Coal, or other material, to be pulverized drops from a hopper 1 through an annular aperture 4 into the stream of shot and is pulverized by the impact therewith and with the striking surface 12. A suction device 17 draws air and fines through an outlet pipe 16 of a casing 15 above the striking surface 12 and surrounding the hopper 1, from the impact zone, air entering the zone upwardly through the openings 14 in the plate 13. Heavy particles are returned with the shot to the impeller. In another embodiment, Fig. 2, metal shot from a hopper 27 is fed into a stream of pressure air from a pipe 26 whence it passes through a nozzle 23 and along an air duct 24. Coal drops from a hopper 21 through an opening 22 in the duct 24 into the stream and is carried along with the shot to impact against an anvil 28. Pulverized coal passes from the impact zone to an outlet duct 30 while the shot and heavy coal particles fall into a space 36 below the anvil whence a high pressure blast of air from a nozzle 34 carries it up a pipe 35 to the hopper 27. A magnetic separator 37 may be provided adjacent the space 36. Both embodiments are adapted to be carried as a part of a locomotive. Specifications 142,176, [Class 59], and 426.237 are referred to.

Title: Improvements in or relating to electro-metrical measuring apparatus
IPC: G01N27/333
Filed: 1937-11-23
Abstract: 492,936. Determining physical properties of materials. SIEMENS & HALSKE AKT.-GES. Nov. 23, 1937, Nos. 32263, 32254, and 32255. Convention dates, Nov. 23, 1936, Feb. 6, 1937, and Feb. 22, 1937. [Classes 37 and 53] A diaphragm electrode, for example of glass, in electrometrical measuring apparatus such as ion concentration meters, has applied to one side an electrically-conductive substance making the electrode resistant to pressure and insensitive to temperature variations. The conductive substance can be a thin layer produced by metallizing, and the electrode can be filled with a liquid having the same cubic expansion coefficient as that of the electrode material. The liquid fillings can serve both as electrically - conductive coatings and also as means providing resistance to pressure and temperature variations. In Fig. 1, a glass electrode 1 partially metallized on the exterior, has a diaphragm 2 which is metal-coated at 3, and a metal jacket 4 is soldered to the electrode at 5, and mounted in the flow-through vessel 9. In Fig. 2, the glass is metallized inside and has an internal metal member 10 and buffer liquid 11, the filling hole for which is closed by an electrically-conductive plug 13 having a capillary bore 14. In another construction, the whole of the glass tube is filled with liquid and provided with a metal top. The liquid fillings can be wholly or partly solidifying materials such as gelatinizing liquids, solidifying liquids due to evaporation of solvents, e.g. varnishes or resins, and solidifying plasters and cements. Conducting substances such as cuprous oxide or silver sulphide can be used in addition. In Fig. 4, a filling substance 22 with a platinum, silver or other metal conductor 23 is provided. The filling 22 may be given a particular ion concentration by adding chlorides, acids, bases or other electrolyte. When substances containing hydrogen ions are added, quinhydrone may be employed to maintain constancy of the hydrogen potential. Fig. 6 shows a metallized glass with filling 30 of gypsum and a gelatinizing layer 29, a metallic conductor or leakance 31 being connected to the metallized layer 32. Fig. 7 shows a hollow electrode 33 filled with a liquid which, if nonconductive, is rendered conductive by adding salts. The diaphragm 34 is protected by a sieve or porous member 35. In another construction, the electrode is formed with a hollow wall, the space being filled with liquid and the glass diaphragm being located between the wall and the main glass body.

Abstract: 672,770. Travelling-wave tubes. RADIO CORPORATION OF AMERICA. Dec. 8, 1947 [Jan. 25, 1947], No. 32340/47. Class 39 (i). A travelling wave amplifier has separate input and output helixes 5, 6, Fig. 1, terminated non-reflectively at either end, and the beam after being modulated by the helix 5 is accelerated by a D.C. field before passing into the second helix 6 so as to increase the output energy. The helix 6 is preferably of variable pitch, as shown, to correspond with the progressive reduction in beam velocity, and the helix 5 may or may not be of variable pitch. The input and output are injected and removed via coaxial lines 20, 37, the inner conductors of which are helices of varying pitch to match the impedance of the helices 5, 6. The free ends of the helices 5, 6 are terminated by non-reflective resistors R, R<SP>1</SP>. The envelope of the device comprises two non-magnetic metal cylinders 10, 18 with dielectric 19 between, 18 being more positive than 10, and a partition 11 with an aperture 15 for the beam shields the helices 5, 6 from one another and prevents feed-back. A coil 26 focuses the beam. In a modification, Fig. 2 (not shown), the envelope 10 is grounded instead of being at a negative potential relative to ground as in Fig. 1. In a further modification, Fig. 3 (not shown), the output helix 6 is constructed of overlapping portions with semi-conducting material such as titanium dioxide interposed so as to provide resistances for D.C. but negligible impedance for the travelling wave; a positive D.C. bias is applied to helix 6 so that an axial potential gradient is set up along the helix. The coaxial line connected to the output helix is joined to a quarter-wave sleeve located in a metallic enclosure. The sleeve forms one pole of the output and the inner conductor is capacitatively coupled to the enclosure to form the other pole of the output and directly connected to the positive battery terminal. The tube corresponding to 18 may be connected to a top on the battery or to ground; in the latter case the dielectric sleeve corresponding to 19 may be dispensed with.

Title: The resolution of 1-hydroxy-2-amino butane
IPC: C07C59/50
Filed: 1964-08-10
Abstract: Mixtures, e.g. racemic mixtures of (+) and (-) 1-hydroxy-2-aminobutane are resolved by reacting them in aqueous solution with an equimolecular amount of (+) tartaric acid, separating the diastereoisomeric salts by fractional crystallization, and purifying the (+) hydroxyaminobutane (+) hydrogen tartrate by treating with methanol a crystalline fraction rich in it, e.g. by grinding or stirring.  Using repeated concentration and cooling for the fractional crystallization, the (-) HAB (+) hydrogen tartrate crystallizes first, as the monohydrate. Several fractions of each diastereoisomer are obtained, and are washed with methanol or ethanol.  The hydroxyaminobutane stereoisomers are obtained from the hydrogen tartrates by passing their aqueous solution through an ion-exchange resin, or by treating the solution with lime water to precipitate calcium tartrate, followed by distillation.
