Title: Improvements in or relating to circuit arrangements including electron tubes for very short waves
IPC: H01J25/38
Filed: 1954-09-23
Abstract: 758,797. Protective arrangements for tube circuits. SIEMENS & HALSKE AKT.-GES. Sept. 23, 1954 [Sept. 23, 1953], No. 27538/54. Drawings to Specification. Class 40 (6). In an amplifier or oscillator using a tube such as a travelling-wave tube in which a beam of electrons is guided past an electrode which is at a positive potential (for example a helix), means are provided to develop a voltage dependent upon the current to the electrode and to apply the voltage to a control electrode whereby the current to the first mentioned electrode is maintained at a low value. As described a resistance is inserted in the part of the cathode lead common to the helix and Wehnelt cylinder circuits whereby an increase in helix current increases the bias on the Wehnelt cylinder and first improves the focusing and then as the voltage rises further reduces the beam current.

Title: Production of derivatives of 1, 4-bis-(styryl)-benzene
Inventor: STILZ WALTER
IPC: C07C17/26
Filed: 1960-08-11
Abstract: Compounds of the 1,4-bis-(styryl)-benzene series are prepared by reacting a benzylphosphonic acid which is not substituted in paraposition by a free or esterified carboxylic acid group and whose carbon atom attached to the phosphorus atom bears at least one hydrogen atom, or an ester of the same, with a 1,4-diacylbenzene (acyl includes -CHO) in the presence of a proton acceptor.  An inert solvent, especially a polar solvent, may be used.  The phosphonic compound may be of formula <FORM:0920988/IV(a)/1> where R, R1, R2 and R3 may be hydrogen, aliphatic groups, especially alkyl, halogen, free, esterified or etherified hydroxy, sulphonic acid, sulphonic acid amide, nitrile, carboxylic amide, or, except for R, free or esterified carboxylic groups.  R and R1, R and R2 or R and R3 may also be members of 5- or 6-membered cyclic diethers annellated with the benzene ring through the oxygen atoms, the carbon atoms in the ether rings being substituted if desired.  R4, R5 and R6 may be hydrogen or aliphatic, especially alkyl, groups; R5 and R6 may also be aryl or may be linked in a ring with the phosphorus.  The benzene ring may form part of a naphthalene system.  Carboxylic amide groups may be N-substituted, e.g. by C1-6 alkyl or by alkylene completing a ring with the nitrogen.  The diacylbenzenes may be of formula <FORM:0920988/IV(a)/2> where R7, R8 and R9 may be hydrogen, or aliphatic or araliphatic, especially alkyl, groups.  R7 and R8 may also be halogen, free, etherified or esterified hydroxy, or sulphonic acid groups.  The bis-(styryl)-benzenes may be of use as optical bleaches for synthetic and natural macromolecular substances, and as light protective agents, stabilizers, pesticides and dyes.  Examples describe the preparation of: 1,4-bis-(31,41-methylenedioxystyryl)benzene; 1,4-bis-(m- and p-cyanostyryl)benzenes; 1,4-bis - (p - methoxystyryl)benzene; 1,4-bis-(31,41-dichlorostyryl)benzene; 1,4-bis(p-chlorostyryl) benzene; 1,4-bis(21,41-dichlorostyryl)benzene; and 1,4-distyryl-2,5-dichlorobenzene.  The diethyl esters of the following benzylphosphonic acids are prepared as starting materials from triethyl phosphite and appropriate benzyl halides: 3,4-methylenedioxybenzyl; m- and p-cyanobenzyl; p-methoxy-benzyl; 3,4-dichlorobenzyl; p-chlorobenzyl; and 2,4-dichlorobenzyl phosphonic acids.
Patent GB-463970-A (GB)
Title: The manufacture of halogenated derivatives of methane
IPC: C07C17/093
Filed: 1935-10-08
Abstract: Fluoro-derivatives of methane are obtained by subjecting a mixture containing carbon disulphide, hydrofluoric acid, and a halogen other than fluorine to the action of a heavy metal halide other than an antimony halide at elevated temperature.  The hydrofluoric acid or halogen or both may be present in such quantity that part passes through the reaction chamber unchanged. Suitable metal halides are ferric, cupric, and zinc chlorides, cupric bromide, and chromium fluoride, which may be supported on carriers such as coke, or used in molten form.  Mixtures of salts of which one at least is a catalyst may be used, e.g. ZnCl2 + FeCl3 containing 69 per cent of the former. Insufficiently fluorinated derivatives can be contacted again with the catalyst and further quantities of reactants.  Nickel or graphite are suitable materials for construction of the apparatus. Gaseous HF may be bubbled through heated CS2, chlorine added, and the vapours passed over coke + 10 per cent CrF3 or CuCl2, the temperature being, e.g., 400--500 DEG  C. in the former case and 300 DEG  C. in the latter, and the time of contact 10 secs.  In examples: (1) CuCl2 at 200 DEG  C. yields a mixture of chlorofluoromethanes mainly dichlordifluoro-methane which is separated by cooling and fractional distillation; (2) coke + CuCl2 at 300 DEG  C. is used giving CF2Cl2 and CFCl3, the latter being recirculated with more HF to give CF2Cl2; (3) coke + CrF3 at 450--500 DEG  C. yields CF3Cl, CF2Cl2, and CFCl3, this last being further converted.  Specification 454,577 is referred to.
