Title: Improvements relating to the analysis of samples of material
Inventor: JONES ROBERT EARROL
IPC: G01N23/222
Filed: 1966-02-09
Abstract: 1,114,351. Reciprocating conveyers. KAMAN AIRCRAFT CORPORATION. 9 Feb., 1966, No. 5588/66. Heading B8A. [Also in Divisions B4 and G1] In activation analysis, a specially designed transfer means is used to transfer simultaneously samples from an exposure position in proximity to the source to different detection positions in proximity to the detection apparatus, the time taken to transfer a sample from the exposure position to its respective detection position being substantially the same for all said samples. The transfer means is especially adapted for use in neutron activation analysis of the oxygen content of beryllium samples on a mass production basis. A pair of samples, one standard 42, one unknown 40, are located in superimposed relationship adjacent the target 38 of the neutron generator 10 and receive the activation dose. The transfer means 14 then transfers the samples 40, 42 to positions adjacent respective counters 36, 34 which are spaced and partially shielded from another. The counters may be of the type employing a thallium activated sodium iodide crystal. A counter located inside the neutron generator tube 11 monitors the neutron flux. A neutron source for each sample may be provided. The transfer mechanism 14 is a collapsible parallelogram swing linkage functioning as a high amplitude pendulum, all parts of which are of polyethylene, except for the stainless steel bearings. It comprises two pairs of pivoted links 48, 50, the former supporting a bracket 44 on which is mounted the standard sample 42. Between these links is a platform 46, whose central bracket carries the unknown sample 40. On one support shaft 52 is mounted a booster spring which helps the mechanism overcome the friction of the bearings &c. as the linkage swings under gravity from the exposure position to the detection position. The swing back to the exposure position is power-assisted by a motor (60, Fig. 3, not shown) to overcome the effect of the spring. The torque of the spring is adjustable by means of an anchor (56) and thus allows the transfer time to be accurately set. This is a necessary feature since after exposure the samples are radio-active and the decay rate is very rapid. The mechanism functions to swing from the exposure to the detection position in which the samples 40 and 42 are located accurately and in a shock-free manner adjacent the windows of the respective detectors 36, 34 (Fig. 2, not shown). At each extreme position solenoid-operated latches 66 support the linkage for the periods of exposure and detection, respectively.

Title: Method for recovering the constituents of spent reaction masses obtained in the production of organo-halogen-silanes
IPC: C01B33/02
Filed: 1953-02-27
Abstract: In the production of organo-halogen-silanes by reacting a halogenated hydrocarbon with silicon in the presence of copper or cuprous chloride, silicon and copper are recovered from the spent reaction mass by dispersing said mass in water or dilute hydrochloric acid and treating with chlorine at a temperature of 20 to 100 DEG C., separating the remaining solid which is substantially pure silicon, reducing and neutralizing the resulting solution, and separating the precipitate of cuprous chloride produced.  The chlorine treatment is preferably effected at 75-80 DEG C.  The reducing agent is preferably sulphur dioxide, sodium bisulphite or sodium sulphite.  When the spent reaction masscontains metals other than copper which are capable of forming water-soluble chlorides, the solution remaining after separating the precipitated cuprous chloride may be treated with an alkali metal or alkaline earth metal hydroxide or an alkali metal carbonate in order to precipitate said metals.  The free metals are obtained from the precipitate by known methods.
