Abstract: 831,545. Ionisation counters. ATOMIC ENERGY OF CANADA Ltd. April 1, 1957 [April 20, 1956], No. 10580/57. Class 39(1). [Also in Group XL(b)] The radiation detector tube comprises two counters of the Geiger Mueller type and 9 and 10, Figs. 2 and 3, are the anode and cathode of the first detector, 12 and 11 the anode and cathode of the second detector, the two cathodes being electrically joined externally. The tube is demountable to allow the material to be investigated to be deposited on the inner surface of the tube forming the cathode 10. This cathode consists of a tube of aluminium some 0À0008 inch thick and forms an alpha particle filter. After assembly the ionising gas is introduced at the valve 14. In operation the first detector is subjected to all the radiation produced by the particles emitted from the material under test but because of its operation on the proportional part of its characteristic it responds only to the alpha radiation. Because of the action of the alpha particle screen the second detector is subjected to beta radiation only. The detector tube forms part of radiation counter which measures the radiation from long lived alpha particle emitters, e.g. radium in the presence of radiation from short lived alpha particle emitters, e.g. the decay products of radar, in which the emission of an alpha particle is preceded by the emission of a beta particle. The circuit operation is described in Group XL(b).

Abstract: 120,359. Hampton, C. W., and Davies, L. June 29, 1918. Vices.-In a vice of the kind in which a quick adjustment is effected by releasing a divided nut from the operating screw by turning a longitudinally arranged blade, the halves of the nut moving apart in parallel relation against the action of springs, the blade passes through lugs on the lower half of the nut and is adapted when turned to engage lugs on the upper half of the nut. The nut is carried in a housing close to the front of the screw so that the screw and blade may be shorter than usual and so that the nut is readily accessible. As shown, the two half-nuts 8, 9 are arranged between lugs 6, 7 on the base 5 close to the front end of the operating screw 3. The half-nuts 8, 9 have depending lugs 11, 10 and the blade 13 passes under the lugs 10 and through holes 12 in the lugs 11 and is guided also by passing through circular holes in the lugs 6, 7. By turning the blade 13 by a finger lever 16 the half-nut 9 is raised and the half-nut 8 is depressed so as to free the screw 3. On returning the blade 13 to normal position, the half. nuts are moved into engagement with the screw by springs 18 mounted on screws 17 which are secured to the half-nut 9 and pass freely through holes in the half-nut 8.

The hydrophilic portion of the polymer may be supplied by units from a monomer having multiple ether or thioether groups, a carbonyl group, a carboxylic acid group, a carboxylic ester group carrying an alcohol residue of not more than 6 carbon atoms, an amide group or an amino group.  The amino or amide groups may be substituted.  Typical polymers are polymers of N-tert-dodecylaminoethyl methacrylate and of N-tert-alkylaminoethyl methacrylate with the tert-alkyl group being a mixture of 18-21 C., 12-14 C. and 9-10 C. groups.  The polymer may be applied to the dithiocarbamate in a mineral oil, benzene, toluene, xylene, aromatic naphtha, chloroform, ethylacetate and butyl acetate.
