Filed: 1960-10-27
Abstract: The invention comprises thiophosphoric acid esters of the general formula:  <FORM:0927690/IV(a)/1> in which R1 and R2 are alkyl radicals containing up to 4 carbon atoms at least one of which is substituted by a C1-C4 alkylmercapto group, di C1-C4 alkylamino group, C1-C4 mono- or dialkylamino-carbonyl group, or C1-C4 alkoxy-carbonyl group, or by a halogen atom and R3 is a phenyl group which may be substituted by a C1-C4 alkyl group and/or nitro group and/or halogen atom.  They may be obtained by reacting appropriate trialkyl phosphites, at least one alkyl radical of which is substituted as above for the radicals R1 and R2 with aromatic sulphenyl monophosphorothioate- or dithioates of the general formula <FORM:0927690/IV(a)/2> wherein R is an alkyl radical, X is an alkyl, alkoxy, or aryl radical and R11 is as defined above for R3.  The reaction should preferably be effected at below 50 DEG C. and in the presence of a solvent e.g. a hydrocarbon or chlorinated hydrocarbon. Compounds having the formula:  <FORM:0927690/IV(a)/3> in which R and X are as defined above and R1 is an alkyl radical which may be substituted as defined above for the radicals R1 and R2 are also obtained as by-products.  Several examples are given and the products have pesticidal properties (see Group VI).  Specification 909,325 is referred to.ALSO:A pesticidal composition comprises a solid or liquid carrier or diluent and as active ingredient a thiophosphoric acid ester of the formula <FORM:0927690/VI/1> in which R1 and R2 are alkyl radicals containing up to 4 carbon atoms at least one of which is substituted by a C1-C4 alkyl-mercapto group, di C1-C4 p  alkylamino group, C1-C4 mono- or di-alkyl-amino carbonyl group or C1-C4 alkoxycarbonyl group, or by a halogen atom and R3 is a phenyl group which may be substituted by a C1-C4 alkyl group and/or nitro group and/or halogen atom (see Group IV (b)).

[Also in Division H5] A conveyer apparatus suitable for irradiating materials is shown in Fig. 2 and it comprises a column 25 supporting a plate 23 on which spindles and rollers e.g. 37, 38, 32, 34, are mounted perpendicular to the plate. The rollers are distributed around a central hollow roller 30 which carries a radio-active source. The band 2 containing grains (1) (Fig. 1, not shown) of maize to be irradiated is disposed in a circuit around the rollers which may be tensioned utilizing for example movable rollers 34 which may be adjusted in slot 50 by weight 49. At least one of the rollers is driven e.g. by motor 43 and pulley 39 so as to move the band around the circuit. A desired oscillatory movement between the band and the radioactive source is achieved by means of a pneumatic or hydraulic cylinder 17 operating rod 18 so as to reciprocate tube 25 in standing tube 13. Alternatively, the plate may be fixed and the source moved. The conveying unit may be fitted with a cover plate 52 to which a guide plate 51 for the band 2 is fixed. The circuit around which the band travels is preferably closed the band being a closed loop (Fig. 1, not shown), and in a preferred embodiment (Figs. 4 and 5, not shown), the band is formed in two parts which fit into each other to form a container into which, at one point in the circuit, material may be introduced and from which at a further point by separating the parts, material may be continuously withdrawn e.g. by hoppers in appropriate positions.

In a method of making metal strip by peeling a surface layer from a rotating metal billet, a power driven, cooled, rotatable spindle 24 has a billet 36 secured thereto by a chucking device 30, and a cutting tool 64 clamped in holding means 50, 60, is advanced by screw and nut means 54, 52 into the workpiece at a predetermined rate so as to peel a strip 120 from the workpiece as it rotates with the spindle, tension being applied to the strip to pull it over the cutting tool, the tension being regulated to control the thickness of the strip. Winding up means 12 is provided to initially wrap and subsequently coil the strip on to the mandrel 104 of a wind-up device, the wind-up device incorporating torque controlling means which tensions the strip during the coiling operation, sensing means (not shown) being provided to control the tension in relation to the thickness of the strip. To prevent inaccuracies in the finished strip due to fluctuations in temperature during the peeling operation, the machine spindle 24 and the chucking device are provided with passages 38, 40, for coolant and the external surface of the workpiece is cooled during the peeling operation. At the commencement of the peeling operation means in the form of a rotating wire brush 90 is provided to straighten the end of the strip to facilitate its feeding through supporting means 112 and 120 on to the coiling mandrel 104. The wrapping device 106 and the brush 90 are displaced so as to be inoperative whilst the coiling operation is in progress. The cutting tool 64 which has an insert 66 is rigidly secured in the tool holder 60 by a wedge member 80 so as to prevent vibration during the strip peeling process.
