Title: New thiophosphoric acid esters
Inventor: METIVIER JEAN
IPC: C07F9/165
Filed: 1961-12-20
Abstract: The invention comprises the dextro- and laevo-rotatory isomers of N-methyl-5-(O,O-dimethylthiolophosphoryl) - 3- thia- 2- methylvaleramide each being substantially free from the other isomer. They may be obtained by reacting a halogenophosphate of the formula (CH3O)2P(O)Hal wherein Hal is halogen, preferably Cl, with an optically active isomer of a compound of the formula: X1S.CH2. CH2.S.CH(CH3)CONHCH3 wherein X1 is a hydrogen atom or an alkali metal atom.  The reaction is preferably carried out in an organic solvent medium, e.g. an aliphatic ketone or a hydrocarbon, and when X1 is hydrogen is preferably carried out in the presence of a basic condensing agent, e.g. an alkali metal or an alkali metal hydroxide or carbonate. Alternatively, the products may be obtained by reacting an alkali metal or ammonium salt of O,O-dimethylthio-phosphoric acid with an optically active isomer of a reactive ester of the formula: Y.CH2. CH2.S.CH(CH3)CONHCH3 wherein Y is the acid residue of a reactive ester, e.g. a halogen atom or a sulphuric or sulphonic ester residue (preferably the toluene-p-sulphonic residue).  The reaction may be carried out in water or in an organic solvent, e.g. an aliphatic alcohol or ketone or in an aqueous organic medium, at between room temperature and the boiling point of the reaction medium, or by reacting a phosphorus derivative of the formula:- (CH3O)2P(O)S.CH2. CH2.Y in which Y is as defined above with an optically active isomer of a compound of the formula:- HS.CH(CH3)CONHCH3.  The reaction may be carried out in an organic solvent medium, e.g. an aliphatic alcohol or ketone, at between 15 DEG  and 150 DEG C., e.g. at the boiling temperature of the solvent used.  The products have pesticidal properties (see Group VI). Laevorotatory N-methyl-5-chloro-3-thia-2-methylvaleramide is prepared by reacting 1-bromo-2-chlorethane with laevorotary N-methylthiolactamide in the presence of triethylamine.  The dextrorotatory compound is obtained similarly but commencing with dextrorotatory N-methylthiolactamide.ALSO:A pesticidal composition comprises the dextrorotatory or laevorotatory isomer of N-methyl - 5 - (O,O - dimethylthiolophosphoryl)-3-thia-2-methylvaleramide (see Group IV (b)) in association with one or more diluents compatible therewith and suitable for use in pesticidal compositions. Specified diluents are as disclosed in the parent Specification.

An anti-viral substance is produced by cultivating a species of the Myxobacterales on a conventional nutrient medium, separating the bacteria and mechanically disrupting them in aqueous medium or polar organic solvent and extracting the anti-viral substance from the disrupted cells with a polar organic solvent. The particular species used are Myxococcus xanthus, Myxococcus virescens, Myxococcus rubescens or an unclassified Myxococcus-like species deposited at the Hygienic Institute of Heidelberg University under the designation SA1 and described in " Archiv fur Hygiene und Bakteriologie " 153, (1969) 457-459 (Brauss et al.).

Patent GB-1058741-A (GB)
Title: Improvements in or relating to dosimeters for x-rays and gamma rays
IPC: G01T1/11
Filed: 1963-11-26
Abstract: A radiation dosimeter comprises a thermoluminescent material (e.g. calcium fluoride) mounted on a support, and a heater; the thermal path from the support to the free surface of the luminescent material increases from the edges of the material to its centre, so that, with uniform heating, the whole of the free surface of the luminescent material reaches its emission temperature at the same time.  This enables the radiation dose to be recorded by observing the peak light emission of the dosimeter, rather than integrating its light emission over the whole heating period.  In embodiments, the heater may be a resistive plate, e.g. of carbon, or a radiating filament, and the thermal path may be lengthened by either increasing the thickness of the luminescent layer (e.g. 90 micron at the edges, 150 micron at the centre) or by increasing the thickness of the central portion of a non-metallic support.

A cable guide which surrounds and is axially displaceable along a cable drum and which obtains its axial movement by engagement with cable tracks on the drum, comprises a yoke 2 shaped to fit the cable track over at least half of the drum circumference and being attached to a frame 1 provided with an aperture 3 for guiding the axial movement of the cable guide. The yoke 2 is pinned at 8 to the frame 1 which is shaped at 4 to fit the track, and has a slot 9 through which the cable passes from and to the drum. Resilient pressure rollers 6 are mounted diametrically opposite on projections 5 of the yoke 2 and press the cable into the tracks on the drum. The yoke 2 acts as a torsion spring, keeping the rollers in engagement with the cable and the section of the yoke bar material may be varied to obtain different resilient properties. A third roller may be situated intermediate the ends of the yoke to prevent slack cable leaving the drum. The first said two rollers are positioned equi-distances from the ends of the yoke so that the yoke may be reversed for use with the frame of a drum having a cable track of opposite hand. In the embodiment of Fig. 2 (not shown), the pressure rollers are mounted on leaf springs adjustably secured to the ends of the frame, the cable slot in the latter being open at one end and closed by one end of the yoke when secured to the frame. In a final embodiment of Fig. 5 (not shown), the rollers are mounted on leaf springs which are adjustably secured to holders, to which the ends of the yoke are fixed. The holders are pivotally pinned to the ends of the frame whereby resilience is derived from both the leaf springs and the yoke.
