Abstract: 1350554 Detecting fission products COMMISSARIAT A L'ENERGIE ATOMIQUE 12 Jan 1972 [22 Jan 1971] 1516/72 Heading G1A A method of detection of fission products comprises the electrical collection of such products on both sides of a very thin surface metallized disc of polyester insulating material, which is placed at the centre of a spherical chamber enclosing the sample under test and in which radio-active ions have been permitted to form, and the subsequent measurement of radio activity emanating from the disc by two detectors arranged to receive emanation in the entire solid angle surrounding the disc. An automatic apparatus Fig. 1, in which a disc extracted from a rotating carrier 1 is fed between two closely spaced parallel semi-conductor detectors 4 of the same area as the disc to measure residual activity, is then fed to the centre of spherical sample chamber 3, is returned to the measuring position, and is then extracted and replaced by a new disc. The arrangement may include retractable beta screens 17 on each side of the measuring device whereby gamma, and beta + gamma measurements may be obtained. An inactive gas may be used to sweep the detector and repel gas from the sample chamber, and the readings may be calibrated by the insertion of a standard disc.

Title: Improvements in or relating to apparatus for aspirating predetermined volumes of gases
Inventor: WRIGHT BASIL MARTIN
IPC: G01N1/24
Filed: 1954-01-20
Abstract: <PICT:0756186/III/1> A sampler for aspirating predetermined volumes of gases comprises two containers, one of which is filled with a known volume of liquid, arranged in opposed relationship on a body member carrying a rotatable plug provided with channels to permit liquid to pass from the upper to the lower container thereby aspirating gas into the upper container and evacuating it from the lower.  Inversions of the bottle around the plug permits the operation to be repeated.  The sampler comprises two bottles A screwed into a body member B which rotate around a plug C which may be secured to a framework D for convenience in carrying.  A polythene liner (I) allows easy rotation.  Each of the bottle sockets of the body member contains an air inlet tube H, a jet J and a plain hole K. The plug contains two nozzles F and G arranged as shown to be connected with the holes in the body member.  In operation, the upper bottle is filled with the measured volume of water equivalent to the desired volume of the sample and the plug is arranged as shown. Water runs from the upper bottle through hole K plug passage and jet J into lower bottle and air or gas is drawn into upper bottle via F and H while air from lower bottle escapes via G.  The jets J project some distance from the body of the member to allow a residual suction head when the upper bottle is empty.

Abstract: 712,929. Production of metals; iron. TEXACO DEVELOPMENT CORPORATION. Jan. 22, 1952 [Feb. 8, 1951], No. 1747/52. Classes 72 and 82 (1) [Also in Group XII]  Carbon monoxide and hydrogen are produced and a metal oxide reduced by interaction of the powdered oxide with a dispersion of a solid carbonaceous fuel, gaseous oxygen and steam at a temperature above the fusion temperature of the reduction product. The metal product may be recovered in molten or powdered form. To a mixer 6 are admitted crushed coal through a line 5, water to form a fluid dispersion through a line 7 and iron oxide through a line 8. A flux, oxidation catalyst, defloculating or wetting agent, &c. may also be added through a line 9. The resulting slurry is pumped through a tubular heater 14 which may have venturis or other nozzles to increase turbulence and the disintegrated dispersion of the solids in steam. is discharged to a cyclone separator 17 from which some steam is withdrawn through a line 18 and the rest passes with the solids into gas generator 20 supplied with oxygen through a line 21. Part of the solids may be returned to the mixer through a line 22. Gas, mainly carbon monoxide and hydrogen, is taken off through a line 23, molten slag through a line 24 and molten iron through a line 25. Specification 683,318 is referred to.

According to the invention, the splined engagement of the element 30 is made co-extensive and co-planar with the gear teeth 33 in the clutch disengaged position to prevent the teeth 33, 18 disengaging axially under load, and a member 39 rigid with the hub member 28 is provided which is abutted by the element 30 in the clutch disengaged position to keep the hub member from wandering into engagement. As shown applied to the first and second speed gear train of a four-speed gear-box, a lay-shaft 12, powered from the driving shaft through a constant mesh gear pair (not shown), has rigidly mounted thereon a second speed gear 20 meshing a gear 21 freely mounted on the driven shaft 23 and coacting with the elements 30, 28 splined thereon through teeth 24 and a cone friction element 25- respectively. The first speed gear 18 is also mounted on the lay-shaft 12 to entrain the teeth 33 when the clutch is disengaged by a selector arm 32. The splines on the member 28 are cut off at a point 50, Fig. 2, co-planar with the inner end of the gear teeth 33 when the latter are fully engaged, the remaining plain portion of the member 28 serving to prevent fouling of the neutral seating notch 37. The member 39 is splined on the driven shaft 23 and is threadedly connected with the member 28 to allow relative axial ,adjustment before setting up.

Title: A process for the manufacture of phenylhalosilanes
IPC: C07F7/12
Filed: 1954-01-25
Abstract: Phenylhalosilanes are prepared by reacting benzene with a halosilane at a temperature from 150 DEG  to 550 DEG  C. under a pressure of at least 50 lb. per sq. in., with the continuous or intermittent release from the system of hydrogen formed during the reaction.  The halosilanes are defined as RnHmSiX4-(n + m), where R i an alkyl or phenyl radical, n is 0, 1 or 2, m is 0, 1, 2 or 3, the sum of n + m being not greater than 3, and X is bromine, chlorine or fluorine. When m is 0, a hydrogen halide acceptor is included in the reaction mixture.  Suitable acceptors are silicon, iron, zinc, tin and aluminium.  A catalyst such as a boron or aluminium halide may be present.  The hydrogen may be removed (a) by cooling the apparatus to room temperature, releasing the hydrogen and reheating to reaction temperatures; (b) by means of a disc of a suitable metal such as palladium, platinum or iron, which allows diffusion of hydrogen; and (c) by segregation in a cool part of the apparatus from which it is released by a thermal or density regulated valve.  In the examples, yields are compared of (1) phenyltrichlorosilane, together with some diphenyldichlorosilane and polymeric material having phenylene linked silicon atoms, prepared from trichlorosilane and benzene; (2) phenylmethyldichlorosilane and other phenylated residue prepared from methyldichlorosilane and benzene; (3) phenylchlorosilanes prepared from trichlorosilane and benzene; (4) and (5) phenylchlorosilanes prepared from silicon tetrachloride and benzene.
