Title: X-ray generation using a secondary emission electron source
Inventor: PRICE JOHN SCOTT
IPC: H01J35/06
Filed: 2008-02-05
Abstract: A method and apparatus are provided for generating high frequency electromagnetic energy, such as x-rays, using a secondary electron emission source 10. A primary electron emitter 20 provides a primary electron current 26 directed towards a secondary electron emitter 16. The secondary emission member 16 then generates a secondary electron current 28 which causes x-ray generation when impinging upon an anode. The primary electron source 20 may be a field emitter array, a ferro-electric emitter (see Fig 6), or a thermionic emitter (see Fig 5). The secondary electron emitter may be formed of a diamond-like substance or other material with a high negative electron affinity, so that stream of secondary electrons has a current greater than that of the primary electron stream. The x-ray generator may be incorporated into a computed tomography imaging system (see Figs 9 and 10).

Title: Manufacture of cyclic hydrocarbons and derivatives thereof
IPC: C07C1/24
Filed: 1926-04-19
Abstract: 251,270. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). April 24, 1925, [Convention date]. Samples furnished. Cyclic hydrocarbons are obtained by passing the vapours of diaryl ketones or aryl-alkylketones, containing a methyl group or a methylene group in the o-position to the carbonyl group, over highly porous contact material such as silica gel, alumina gel, or highly active charcoal; a further catalytically acting body may be added to the contact mass and the reaction may be carried out under reduced or increased pressure. Substitution products of benzophenone, naphthylketones, and diketones such as isophthaloyl-xylene yield six-membered rings, but by using mixed aliphatic-aromatic hetones, five-membered rings may be formed; thus aceto-m-xylene yields inethylindene. According to examples the following compounds are obtained :-(1) 2-methylanthracene (which yields 2-methylanthraquinone on oxidation with nitric and sulphuric acids) by passing benzoyl-m-xylene vapour over active carbon, made by activating coke with water vapour, heated to 400‹ C.; (2) 1 : 2-benzanthracene from o-tolyl-alpha-naphthyrketone; it yields a picrate with picric acid. The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of the following :-(1) 1 : 3 : 6-trimethylanthracene from 1 : 3 : 1<1> : 3<1>-tetramethylbenzophenone (from phosgene and m-xylene); (2) 6-methyl-1: 2-benzanthracene from alpha- or #-naphthoyl-m-xylene; (3) 1:2:7:-8-dibenzanthraocene from 2-methyl- 1:1<1>-dinaphthylketone (from alpha-naphthoyl chloride and #-methylnaphthalene); (4) a mixture, of 2- methylanthracene and 2-chlor-7-methylanthracene from p-chlorbenzoyl-m-xylene. This subject-matter does not appear in the Specification as accepted. Ketones.-The ketones required in the above process are obtained in known manner by action of acid chlorides upon benzene, naphthalene, &c., in presence of aluminium chloride. The preparation of ketones from acetyl chloride and m- or pxylene, o-toluyl chloride and naphthalene, benzoyl chloride and m-xylene is referred to.
