Title: Pyrazinylphosphoroamidothioates and method for preparing the same
IPC: C07F9/6509
Filed: 1961-02-06
Abstract: The invention comprises O-2-hydroxy pyrazinyl phosphoroamidothioates of the general formula: <FORM:0948522/C2/1> wherein R is one of the following radicals: (a) <FORM:0948522/C2/2> , (b) -NH2, (c) -NH lower alkyl, (d) -N (lower alkyl)2 or (e) -O-lower alkyl and wherein R1 is the radical (a), (b), (c) or (d) as defined above. The lower alkyl radical is defined as an alkyl radical containing up to six carbon atoms.  They may be obtained by reacting an O-2-pyrazinyl phosphorodichloridothioate of the formula: <FORM:0948522/C2/3> (a) with at least one mole of ethyleneimine or a C1-C6 alkyl primary or secondary amine or with a C1-C6 alkanol, the latter being used in such molar proportion as to form the monoester only, (b) and if only the monoamide or monoester is prepared in step (a) treating the resulting product of step (a) with an additional amount of ethyleneimine or C1-C6 alkyl primary or secondary amine, or with a C1-C6 alkanol with the proviso that if the monoester is produced in step (a) no further treatment with the alkanol is effected. The reaction is generally carried out at from about 15 to 100 DEG C.  The products have pesticidal properties (see Division A5).  The O-2-pyrazinyl phosphorodichloridothioate used as starting material can be prepared by reacting 1 mole of an alkali metal salt of 2-hydroxy-pyrazine with a stoichiometric excess of at least one mole of thiophosphoryl chloride.ALSO:A pesticidal composition contains as active ingredient at least one O-2-hydroxypyrazinyl phosphoroamidothioate of the general formula <FORM:0948522/A5-A6/1> wherein R is one of the following radicals: (a) <FORM:0948522/A5-A6/2> (b) -NH2, (c) -NH lower alkyl, (d) -N (lower alkyl)2 or (e) O-lower alkyl, said lower alkyl radical containing up to six carbon atoms, and wherein R1 is the radical (a), (b), (c) or (d) as defined above (see Division C2). The composition may be in the form of a solution in an inert organic solvent or of an emulsion in water and a non-solvent, or may be a solid composition in which a solid carrier, e.g. a clay, talc, or diatomaceous earth is used.  A composition suitable for use as a spray is obtained by dissolving the active ingredient in a solvent comprising 65% acetone and 35% water at a concentration of 0.001%.

Title: Improvements in or relating to methods of and means for starting internal-combustionengines
IPC: F01M5/02
Filed: 1954-02-15
Abstract: 750,037. Turning-gear; heating engines. CHRISTIANSEN, H. Feb. 15, 1954 [Feb. 18, 1953], No. 4364/54. Classes 7(2) and 7(5) [Also in Group XXXIV] In a method of engine starting which includes the steps of feeding warmed oil to the engine 1 and then drivingly connecting an auxiliary motor 6, such as an I.C. engine or electric motor to the engine 1 for starting the latter, the motor 6 drives an energy converter 5, for example a pump, dynamometer or turbulence brake, which heats the oil. The lubricant of the main engine 1 flows through pipes 2 and 7 to the converter 5 which is driven from the motor 6, via a clutch 11; the converter 5 offers considerable resistance to the oil flow and. hence raises the oil temperature. The heated oil may by-pass the lubricating pump of the main engine whilst the latter may incorporate a separate closed system in which oil is circulated before and if desired during the starting operation. With the aid of heat exchangers or coils, not shown, associated with the conduit 7 oil passing to or from the sump of the main engine or the oil in the sump itself can be heated indirectly. The heating process may be accelerated by heat exchangers 9 and 10 which are associated with the pipe 7, the former being in the exhaust pipe of the motor 6 and the latter in the cooling system thereof; the heating coils in the conduit 7 may be arrangedalong or through the walls of the main engine or in the sump. After the oil has been heated valves 3 and 8 in the pipes 2 and 7, respectively, are closed and theclutch 11 is simultaneously opened to enable the motor 6 to store energy in a flywheel 12, which energy assists the motor 6 to start the main engine 1 upon closure of a second clutch 13, the latter being connected to the engine by a reduction gearing 14 and a dog clutch 15; the closing of the valves 3 and 8 and opening of clutch 11 may, however, be delayed until the engine' has started. The main engine 1 may draw its lubricant from a reservoir, not shown, which is included in the circuit and may be heated directly or by heating coils.

Abstract: 798,520. Extruding plastic cable coverings. OSNABRUCKER KUPFERUND DRAHTWERK. Feb. 8, 1957, No. 4380/57. Class 87(2). [Also in Group XXXVI] A thermoplastic or vulcanizable covering 2 is applied to a corrugated metal cable sheath 1 by extrusion, the covering having such a crosssection and internal diameter that it lays itself in radial folds to form longitudinally extending ribs 3 between the corrugations 4. The covering material 7 is delivered from press 6 about a hexagonal hollow mandrel 5, the diameter of which is much larger than that of the cable sheath. A vacuum is drawn between the covering and the sheath, causing the sides of the extruded hexagonal tube to sink down on to the sheath, whilst the corners stand out to form the radial folds. The two facing sides of each fold may be welded together by the effect of the vacuum if the material is sufficiently hot.

Filed: 1936-02-14
Abstract: 470,106. Grinding screw threads. SCRIVENER, A. Feb. 14, 1936, No. 4457. [Class 60] For grinding or finishing a screw-thread, the work-piece a is mounted between centres b carried by a table f which slides freely on bearings g in the direction of the axis of the work and is rotated in contact with a driven grinding wheel i by means of a backing wheel j. When finishing a thread the work is moved past the grinding wheel by means of an adjustable control finger l attached to the grinding wheel head by an arm k. For grinding a thread on a blank, the work-piece is mounted in axial alignment with a master former m driven by a backing wheel j<1> at the same speed as the work and the control finger l is brought into engagement with the thread on the former. In this case a second control finger I adapted to engage the work-piece may be provided to assist in re-positioning the work on the grinding wheel for a secondary or finishing grinding operation.
