Title: Electron discharge apparatus
IPC: H01J25/78
Filed: 1942-04-03
Abstract: 556,530. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. April 3, 1942, No. 4480. Convention date, April 4, 1941. [Classes 39 (i) and 40 (iii)] An electron discharge device of the velocitymodulation type comprises means for projecting an electron beam in a given direction through and beyond an input space, means for establishing in the input space electric and magnetic fields of constant intensity normal to the beam direction and to one another, the strengths of the fields being so adjusted relative to the length of the input space that electrons emerge therefrom in substantially the same direction, and means for generating in the input space a high frequency alternating electric field in a direction normal to the magnetic field. An electron beam from cathode 12, Fig. 1, focused by lens 14, 15, 16, passes into an input space between two plates 17 between which battery 27 maintains a steady potential. Coil 23 maintains a magnetic field perpendicular to the plane of view. The electrons describe a complete number of cycloids in the input space. If now an alternating voltage of a frequency at or near that of the cycloids is applied between plates 17, by transformer 30, the emergent beam is velocity modulated. After correction as to direction by plates 37, and as to dispersion by focusing coil 36, the now-bunched beam passes into a similar output space, wherein energy is delivered up to plates 19, before the beam is finally collected by anode 21. In a modification, the plates 17, 19 are replaced by a resonator 40, Fig. 3, split longitudinally into halves insulated at 41. The tube 44 provides a drift space between the input and output spaces 18a, 20a, which are back-coupled by a line 46. The device may be used as a repeater, Fig. 6, when the input and output spaces are formed by interrupting the central conductors of two coaxial lines 50, 56, near their terminations. Diaphragms 52 with four sectoral apertures convert the ends of the lines into resonant chambers. Anti-resonant chambers 58 prevent leakage along D.C. leads. The alternating electric field need not coincide in direction with the constant electric field, so long as it is normal to the magnetic field ; in Fig. 3 it is perpendicular to the constant field.

Title: Improvements in the production of corrosion resistant coatings on metals
IPC: C23C22/83
Filed: 1946-02-13
Abstract: Zinc (including galvanized metal), iron, steel, copper base alloys, and cadmium are treated to produce a corrosion-resistant black coating thereon by subjection to an aqueous acidic solution consisting essentially of chromic acid or a salt thereof, formic acid or a soluble formate, and a water soluble iron salt to give a visible coating, followed by treatment whilst the coating is still wet with a natural or synthetic tannin or tannin derivative, e.g. gallic or tannic acid, which will react with the iron salt to impart a black colour to the corrosion-resistant coating.  Anions of a mineral acid other than chromic may also be present in the acidic solution in the form either of the acid or of a salt thereof, e.g. cobalt nitrate, zinc nitrate, zinc chloride, sodium chloride, copper sulphate, ferric sulphate to produce a smooth polished surface, the acid being preferable when a formate is used.

Title: Production of p,pí¬isopropylidenediphenol crystals having low phenol content
IPC: C07C37/20
Filed: 1962-02-07
Abstract: In the manufacture of p,p1-isopropylidene diphenol (bisphenol-A) by reacting an excess of phenol with acetone in the presence of an acidic condensing agent, the product is separated as crystals from a reaction mixture which does not contain a hydrocarbon or halogenated hydrocarbon solvent for phenol and in which the weight ratio of the product to phenol is at least 2 : 1. The formation of a crystalline complex of bisphenol-A and phenol is thus avoided and the purification of the bisphenol-A by distilling off phenol therefrom is rendered unnecessary.  The reaction may be carried out at 70-90 DEG C. so that all the bisphenol-A remains in solution, whereafter the mixture is cooled and the precipitated crystalline product separated under the conditions described above.  Alternatively, the reaction may be effected at 40-70 DEG C. to yield a slurry of crystals of bisphenol-A in a phenolic solution of bisphenol-A, the crystals being then separated under the conditions described above.  The process may be effected by continuously feeding acetone and an excess of phenol to a reaction zone, withdrawing a portion of the mixture from the reaction zone, separating bisphenol-A crystals from the withdrawn portion under the conditions described above, and returning the residual mixture, with make-up phenol and acetone to the reaction zone.  Specified catalysts and hydrochloric and sulphuric acids, acetyl chloride, sulphur dioxide, boron trifluoride and acid-activated clays.  Examples are given.

Title: Improvements in and relating to oxidation of organic compounds
IPC: C07C45/28
Filed: 1930-02-15
Abstract: Selenium dioxide, selenious acid or a selenite are used for oxidizing organic carbonyl compounds having directly attached to the carbonyl group at least one methylene (CH2) or methyl (CH3) group.  The methylene or methyl group so attached is oxidized and the selenium compound reduced.  According to one example, acetone is boiled under reflux with selenium dioxide until the latter is completely reduced, and the selenium is then separated from the liquid.ALSO:Oxygenated organic compounds are converted into more highly oxygenated organic compounds (other than carbon dioxide) by treating organic carbonyl compounds having directly attached to the carbonyl group at least one methylene (CH2) or methyl (CH3) group with selenium dioxide, selenious acid or a selenite.  The organic carbonyl compound may be either an aliphatic or an alicyclic compound or an aromatic compound which contains no methylene or methyl groups directly linked to the aromatic nucleus.  Reaction is preferably effected in presence of a diluent or of excess of the organic carbonyl compound itself, at temperatures of 50-150 DEG  C.  In examples, acetone is oxidized by selenium dioxide to pyruvic aldehyde-the oxide being thereby reduced to selenium itself, similarly methylethylketone is oxidized to a mixture of diacetyl and ethylglyoxal, diethylketone to b .g -diketo-n-pentane, acetophenone to phenylglyoxal, propiophenone to acetylbenzoyl, cyclohexanone to cyclohexa-1,2-dione (which may be purified by conversion to a semicarbazone), acetaldehyde (or paraldehyde) to glyoxal or its polymerides, propionaldehyde to methylglyoxal, butyraldehyde to ethylglyoxal, ethyl-malonate to ethyl-mesoxalate or its hydrate, and ethylacetoacetate to ethyl-a .b -diketobutyrate. Cyclopentanone and other cyclic ketones may be oxidized in a similar manner.
