IPC: A01N57/14
Filed: 1963-08-14
Abstract: The invention comprises thionophosphoric esters of formula <FORM:1014346/C2/1> where R is C1- 6 straight chain alkyl, R1 is branched chain alkyl or cycloalkyl, R1 and R2 are hydrogen, halogen, nitro, C1- 6 alkyl, alkoxy, alkylmercapto, alkylsulphoxyl or alkylsulphony, and R3 is hydrogen or halogen, with the proviso that when one of R1 and R2 is alkylsulphony, R1 is cycloalkyl.  They are prepared by reacting a thionophosphoric halide (RO) (R1O)P(S) Hal with a phenol of formula <FORM:1014346/C2/2> either as a salt or in the presence of an acid binding agent.  The products are pesticides. Starting materials of type <FORM:1014346/C2/3> in which R is methyl, R1 is isopropyl, sec-butyl, cyclohexyl or pinacolyl and Hal is chlorine are prepared by the action of sodium methoxide on the corresponding ROP(S)Cl2 compounds. The latter may be prepared by the action of sulphur mono- or di-chloride on R1OPCl2.ALSO:Pesticidal compositions comprise a thionophosphoric acid ester of formula <FORM:1014346/A5-A6/1> where R is C1-6 straight chain alkyl, R1 is branched chain alkyl or cycloalkyl, R1 and R2 are hydrogen, halogen, nitro, C1-6 alkyl, alkoxy, alkylmercapto, alkylsulphoxyl or alkylsulphonyl, and R3 is hydrogen or halogen, with the proviso that when one of R1 and R2 is alkylsulphonyl, R1 is cycloalkyl, together with a solid or liquid carrier.  Other insecticides and/or fertilisers may be present.

Abstract: 1,235,914. Rocket combustion chambers and nozzles - cooling. MESSERCHMITT-BOLHOWBLOHM G.m.b.H. July 5, 1968 [July 19, 1969, No. 32230/68. Heading F1J. The invention relates to a liquid-cooled rocket combustion chamber having a convergent-divergent propulsion nozzle, cooling channels being provided in the wall of the combustion chamber and nozzle, there being at least in the highly heated zones of the combustion chamber and in the region of the throat of the nozzle a number of rows of cooling channels, the rows being spaced apart in the radial direction. The rocket propulsion nozzle shown in Figs. 1 and 2 comprises a convergent portion 1, a throat portion 2 and a divergent portion 3, the throat portion being formed separately and being secured between the convergent and divergent portions, the flanges 4 and 5 of which are secured by bolts. Cooling fluid bores 6 are formed in the convergent and divergent portions, the cooling fluid flowing in an upstream direction with respect to the gas flow through the nozzle; the cooling fluid may be one of the liquid propellents. Two rows 7, 8 of cooling fluid bores 9, 10 are formed in the throat portion 2, the rows being spaced apart radially. Cooling fluid-flows from the bores 6 in the divergent portion 3 into the bores 9, 10 in the throat portion 2, that portion of fluid-flowing through the outer bores 10 passing into the bores 6 in the convergent portion 1, while that portion flowing through the inner bores 9 is reversed in direction at 11 and discharged as a cooling film adjacent the wall of the throat, vanes 12 being disposed so as to impart swirl to the flow of coolant. In Fig. 3 (not shown) both the inner and the outer bores (17), (18) of the throat portion communicate with the bores 6 in the convergent portion and no film cooling is provided. Also, sector-shaped members (19) are provided co-operating with the outer bores (18) to restrict the flow area thereof. The radial position of the members may be pre-set by means of screws (20). In Fig. 5 sector members, 19 are again provided so as to control the flow area of the outer bores 18 but the position of each sector member is controlled automatically in dependence on combustion chamber conditions. Each member 19 is controlled by a piston member 22 having a plunger 22a, the piston being urged inwardly by fluid-pressure in chamber 23 and outwardly by a tension spring 31. Pressure fluid is supplied to chamber 23 through lines 24, 25 under control of a piston valve 27 which is itself controlled by a piston 28 which is responsive to pressure of cooling fluid in a bore 6.

[Class 35] In a synchronous motor of the type employing direct-current excitation the armature is provided with a short-circuited auxiliary winding the pole-pitch of which is an even multiple of that of the main winding and the field-magnet is so arranged that it can produce a flux the pitch of which is the same multiple of the pitch of the working flux as the pitch of the auxiliary winding is of'that of the main winding; by rearranging the field magnet flux as described a braking torque is produced which may cooperate with the effect produced by a damping- winding in the pole faces. The Figure shows such an arrangement in which the stator is the armature and is provided with auxiliary coils 1 of twice the pitch of the main coils 9, 10, Consecutive field magnet poles have opposite polarities in normal work, for braking the polarities of alternate pairs 5 of poles are reversed as indicated by the bracketed letters.

Title: Method of producing concentrated sulphuric acid and oleum from gases containing hydrogen sulphide
IPC: C01B17/775
Filed: 1957-10-22
Abstract: In the production of sulphuric acid or oleum by the combustion of moist hydrogen sulphide-containing gas in moist air, thereby producing gas containing sulphur dioxide and water vapour in which the sulphur dioxide/water vapour ratio is less than one, and catalytic oxidation of the sulphur dioxide without removal of the water vapour, the sulphur dioxide/water vapour ratio is increased to a desired value by the combustion in moist air of a predetermined amount of sulphur, or a combustible sulphur compound which does not contain hydrogen, either together with the moist hydrogen sulphide-containing gas, or separately therefrom, the sulphur dioxide-containing gas produced in the latter case being added to the burnt moist hydrogen sulphide-containing gas. Sulphur compounds specified are carbon disulphide and carbon oxysulphide.  98 per cent sulphuric acid (Example 1) and oleum containing 25.4 per cent free sulphur trioxide (Example 2) may be produced by the combustion of sulphur together with hydrogen sulphide.  Sulphuric acid or oleum may be separated from the mist which results from the process by means of one or more porous filters.
