[Also in Division G1] A system for monitoring a plurality of radioactive samples is characterized in that each sample is sensed by a plurality of detectors and in that in general each detector senses a plurality of samples. As described a plurality of samples E1, E2 . . . Fig. 1, each being mixed with a suitable scintillating agent, are sensed by an array of photomultiplier tubes D1, D2 . . . arranged as shown. The outputs of the photomultipliers are summed, Fig. 6, in neighbouring groups of three by transformers T(n)3 each having three primary windings connected as shown, and each sum signal is passed via a gate P(n)3f, Fig. 7, for quantising and recording. Each gate P(n)3f is opened by a further gate P(n)3 which is connected to the photomultiplier tubes as shown in Fig. 5, and which detects when all three photomultiplier tubes connected to it are producing outputs. The outputs from the photomultiplier tubes are also summed in pairs and these sum signals are gated by signals from gates P(n)2, Fig. 5, quantised and recorded. The recorded data is subsequently analysed and the arrangement is said to produce results which could previously only be obtained by using a plurality of detectors for each sample.

Filed: 1962-10-10
Abstract: A method of improving the flame-resistance of fibre boards derived substantially from woodpulp comprises adding to the wood pulp before forming the boards therefrom first magnesium sulphate and then magnesia whereby the pH of the wood pulp is adjusted to be between 9 and 10.  The pulp may also contain waste paper, asbestos fibres, natural or artificial resins for example the condensation product of meleimine with formaldehyde with 2% hydrochloric acid borax, boron oxide, or phosphoric acid or salts thereof.  The pulp is formed into a mat on a Fourdrinier.  After the mat has been partially dewatered a slurry of magnesia may be added, while after further dewatering a solution of magnesium sulphate may be added.  The mat thus formed may be dried in a roll drier at 140 DEG C., or a plurality of mats may be composed in a platen press at a temperature of 180 DEG C.

A centrifuge for subjecting, e.g. pilots to predetermined accelerations, comprises a nacelle movable along a track in the shape of a closed curve, the nacelle being supported at least radially by a fluid cushion. The track may be circular cylindrical, with bottom and top walls 20, 23 and outer and inner walls 21, 22, the nacelle having air or liquid cushions enclosed by labyrinth seals (Fig. 3, not shown) facing each wall, and being supported against gravity by the bottom wall. The supplies to the cushions are controlled by individual solenoid valves 181. The nacelle contains a pilot's compartment 16 rotatable about three axes by motors (17, Fig. 2, not shown) and is fixed on a telescopic arm 4 mounted on a hub 3. The nacelle is propelled by a rearward escape of fluid from the cushions and is braked by reducing the cushion pressure on the outer side to allow the peripheral seal of the cushion to contact the outer wall 21. In another embodiment (Fig. 4 not shown) the nacelle is supported against gravity by the arm (4), and is propelled by a jet engine (47) on the arm. The track (2) is part spherical and the nacelle is a body of revolution around the arm axis. The compartment is rotatable relative to the nacelle about two axes, and the nacelle is rotatable about the other axis, which is the axis of the arm. In another embodiment (Figs. 5-7, not shown), the track is oval in outline and rectangular in section having inner and outer and bottom walls. Several cushions are used for each wall, each of those on the curved walls being pivotally mounted and guided by springs. The nacelle has a pivot pin (A) slidable in a slot (B) in the arm. In modifications, the arm may be omitted and the nacelle may be driven by an electric or turbine linear motor.

Title: Process for preparing diacylperoxides
IPC: C07C409/34
Filed: 1961-10-30
Abstract: Aliphatic or aromatic diacylperoxides are prepared by heating an acyl chloride with hydrogen peroxide and an alkali metal hydroxide at 40 DEG  to 65 DEG C. in the presence of water and cooling the product directly the reaction is complete. It is preferable to preheat the hydroxide to 30 DEG  to 50 DEG C. and to agitate the reaction mixture at 50 DEG  to 60 DEG C.  Acidification of the warm reaction mixture is necessary when preparing diacylperoxides of long-chain aliphatic acids to prevent the formation of foams and emulsions. In a preferred embodiment a solvent, or solvent mixture, in which diacylperoxides are highly soluble in the warm but not in the cold and which is immiscible with water, e.g. a saturated hydrocarbon or carbon tetrachloride, is used together with water to prevent foam and emulsion formation; the diacylperoxide being obtained by cooling the organic phase. Both methods, i.e. with and without the immiscible solvent, may be performed batchwise or continuously and it is of advantage to leave a small amount of acyl chloride in the solvent, which in the continuous process, may be recycled with the solvent. The examples illustrate the preparation of dilauroyl dibenzoyl, dicapryloyl and diisovaleryl peroxides.
