Title: Improvements relating to thermionic valves
IPC: H01J7/18
Filed: 1929-05-13
Abstract: 311,654. Loewe, B. May 12, 1928, [Convention date]. Vacuum tubes.-In a method for dispersing substances exercising a getter action or for activating a cathode, conductors are provided in the valve and so shaped that portions thereof are more strongly heated by the eddy currents induced, the substance to be dispersed being disposed at these portions. In one manner of carrying the invention into effect, the anode of a thermionic valve is utilized as the conductor and the materials described in Specification 306,960 are placed on the interior of the anode at the highly heated portion. Narrow longitudinal slots 2 are formed in the anode 1, the effect being to concentrate the eddy currents into a small space 3 between the slots, a tablet 4 of the material to be dispersed being placed on the space in the interior of the anode. To increase the effect of the slots 2, sheets of mica 5 are inserted therein. Where the material to be heated is an electric conductor, the space 3 is made very small and the material is not in contact with the anode, being heated by radiation from the space 3 and carried by an independent support from the footstep of the valve.

Title: Resolution of racemic compounds
IPC: C07F15/06
Filed: 1963-04-17
Abstract: Racemic naturally-occurring amino acids in the form of derivatives of the amino group and optionally of any hydroxyl or mercapto group present are resolved by reacting them in an aqueous medium with an optically-active metal complex which is capable of supplying a univalent, bivalent or trivalent cation and is resolvable into optical antipodes, the reaction components and conditions being such that one of the two possible diastereoisomeric salts formed has a materially lower solubility in the aqueous medium than the other possible diastereoisomeric salt as well as having a sufficiently low solubility in the aqueous medium for ready separation therefrom.  The separated diastereoisomers may be subjected to double decomposition to yield the required optically active amino acid derivatives, and these may be subsequently converted to the corresponding optically active amino acids.  Examples describe the resolution of N-benzoyl-valine, N-tosyl-serine, N-benzoyl-alanine and its subsequent hydrolysis to alanine, formyl-tyrosine, bis-formyl-cystine, phthaloyl-leucine, phthaloyl-glutamic acid, ortho-carboxybenzoyl-a -alanine and ortho-carboxybenzoyl-phenylalanine.  Specified resolving agents are those providing dextro- or laevo-forms of cis-dinitrobis-(ethylenediamine) cobalt (III) ions, oxalatobis-(ethylenediamine) cobalt (III) ions, oxalatobis-(ethylenediamine) chromium (III) ions, cis-dinitro-(tri-ethylenetetramine) cobalt (III) ions, cis-dinitro-bis-(1-propylene diamine) cobalt (III) ions, oxalatobis - (1 - propylenediamine)-cobalt (III) ions, fluoro-, chloro-, nitro- or thiocyanato -amminobis-(ethylenediamine)-cobalt (III) ions, tri-phenanthroline nickel (II) ions, tris-(ethylenediamine) cobalt (III) ions, tris-(1-propylenediamine) cobalt (III) ions and aquo-ammino-bis -(ethylenediamine) cobalt (III) ions, the preparation and resolution of which is also described.

Filed: 1959-05-06
Abstract: Hydrocarbon material derived from petroleum oil is treated with oxygen at a temperature of 175-400 DEG C. preferably 250-350 DEG C. and then thermally cracked to produce coke.  The coke may be converted into moderator graphite.  The hydrocarbon material treated may be derived from crude oil by distillation and/or cracking, reforming, desulphurization, alkylation, or polymerization.  It may be a "cycle" oil preferably having a boiling range of 300-500 DEG C. or a heavy bottom product of the distillation of a thermally reformed naphtha.  The oxygen may be pure or in the form of air.  50-175 gm. of oxygen per kg. of hydrocarbon material may be used.  The oxidation treatment may be at atmospheric or superatmospheric pressure, e.g. 2-5 atmos. abs. Coking may be effected by passing the oxygen-treated material, optionally diluted with nitrogen, through a fluidised bed of carbon particles, at atmospheric or superatmospheric pressure, e.g. up to 4 atmos. abs. and a temperature of 450-650 DEG C. for a contact time of 5-60 secs.  The resulting coke may be calcined in a rotary kiln at a temperature of 1100-1400 DEG C.  After grinding and sifting the calcined coke may be mixed with a binder and graphitised. The binder may be coal tar pitch or hydrocarbon starting material.
