Title: Improvements in files
IPC: B23D71/00
Filed: 1945-05-29
Abstract: 593,273. Files. NICHOLSON FILE CO. May 29, 1945, No. 13458. Convention date, June 26, 1944. [Class 61 (ii)] A file having arcuate teeth divided into lands by notches is designed to perform both roughing and finishing operations. The file body 10 is provided with arcuate teeth 13, their concave sides facing the end of the file at which the tang is situated. The centres about which the arcuate teeth are generated are located to one side of the central longitudinal axis of the file, such that the angle between the tangent to the arc and the leading edge is substantially a right angle and the angle between the tangent of the arc and the trailing edge is approximately 37 degrees. Each file tooth is divided by a plurality of notches into arcuate lands. The notches 13c are V-shaped, and are arranged in rectilinear series, the leading notch of each series being at or near the leading edge of the file and the last notch of each series being at or near the trailing edge of the file. Where the notches are equidistant and parallel, the arcuate lands vary in length. As the general method of using a file is to move it towards the left and away from the body to some extent, the shorter arcuate lands near the leading edge of the files and angularly displaced substantially perpendicular to the direction of movement of the file act as a roughing file. The longer lands meet the work at a more acute angle and hence act as a smoothing file.

Abstract: 918,536. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 21, 1959 [April 26, 1958], No. 13510/59. Drawings to Specification. Class 39 (4). In a gas-cooled nuclear reactor a fracture in a fuel element sheath is detected by measurement of coolant gas radio-activity. A detector is connected to decay chambers which are each in communication with a cooling channel. Each chamber contains an electrode which is normally at a high negative voltage and which therefore collects the positive ions from the short lived fission products in the coolant gas. The electrodes are earthed in sequence to permit the flow of ions to the detector from the chamber having the un-earthed electrode. The detector comprises a scintillation counter sensitive to Beta-rays in association with an ion collecting device. The latter may be a fixed electrode, a moving wire or a cooled metallic surface. The sequential energization of the electrodes in the decay chambers is effected by a relay system energized from a motor-operated rotary switch. Where a large number of coolant channels are to be monitored they may be associated together in groups, each of which has a separate detector system. Specification 819,366 is referred to.

Title: Improvements in or relating to a method for chlorinating 3a,4,7,7a-tetrahydro-4,5,6,7,8,8-hexachloro-4,7-methanoindene and the resulting product
Filed: 1951-06-07
Abstract: Chlordene (3a,4,7,7a - tetrahydro - 4,5,6,7,8,8-hexachloro - 4,7 - methanoindene) is chlorinated by reacting it with chlorine in the presence of a polyvalent metal silicate catalyst, e.g. montmorillonite, beidellite, nontranite, hectorite, saponite, talc, biotite, muscovite, clays, kaolinite, attapulgite and the zeolites. The chlorination is carried out until not more than about 1.25 and preferably 1 mol. of chlorine has reacted per mol. of chlordene, and may be effected at below 160 DEG  C., preferably between about 15 DEG and 45 DEG  C.  The product contains a preponderant amount of 1,4,5,6,7,8,8-heptachloro-3a,4,7,7a - tetrahydro - 4,7 - methanoindene and also smaller amounts of chlordane (2,3,4,5,6,7,8,8-octachloro - 3a,4,7,7a - tetrahydro - 4,7 - methanoindene) and 1,2,3,4,5,6,7,8,8 - nonachloro - 3a,4,7,7a - tetrahydro - 4,7 - methanoindene.  The chlorination is preferably carried out in the presence of an inert solvent which is later removed, e.g. by distillation at reduced pressure.  The mixture obtained may be used directly as an insecticide, or the more potent heptachloro compound may be isolated, e.g. by crystallization or chromatographic means.  In an example chlorine is added to a mixture containing chlordene, carbon tetrachloride and activated fuller's earth, while the temperature is maintained at about 25 DEG  C. to yield a product containing 74 per cent of the heptachloro compound, the remainder being chlordane.  Other examples are given in which attapulgite, diatomaceous earth, fuller's earth, kaolin, synthetic aluminium silicate, and aluminium silicate are used as catalysts. Specification 618,432 is referred to.ALSO: 1,4,5,6,7,8,8-Heptachloro-3a,4,7,7a-tetrahydro-4,7-methanoindene p and mixtures thereof with the corresponding octachloro compound (chlordane) and nonachloro compound, obtained by the chlorination of chlordene (4,5,6,7,8,8-hexachloro-3a,4,7,7a-tetrahydro-4,7-methanoindene) in the presence of a polyvalent metal silicate catalyst (see Group IV (b)), are used as insecticides.  The heptachloro compound may be purified by crystallization from solution in methanol, butanol, pentane or hexane.  Examples are given of the effect on roaches of the heptaocta- and nona-chloro compounds when dissolved in deodorized kerosene.  Specification 618,432 is referred to.
