Title: Sulfamoylphenyl organic phosphates and thiophosphates and methods for their preparation
IPC: C07F9/12
Filed: 1960-05-20
Abstract: The invention comprises a sulphamoylphenyl phosphate or thiophosphate of the formula:-  <FORM:0917948/IV (b)/1> wherein each R1 is the same or different and is a C1-C4 alkyl radical, A is an oxygen or sulphur atom and each R2 is the same or different and is a hydrogen atom or a C1-6 alkyl radical.  The products may be obtained by (a) condensing under alkaline conditions a 1-phenol-4-sulphonamide of the formula: <FORM:0917948/IV (b)/2> with a phosphorus compound of the formula (K)(K)Y.X where X is chlorine or bromine, K is chlorine, bromine or -OR1 (where R1 <FORM:0917948/IV (b)/3> is as defined above) and Y is or <FORM:0917948/IV (b)/4> to form a compound of the formula: <FORM:0917948/IV (b)/5> (b) and when K is Cl or Br treating with R1OH in the presence of an acid acceptor to convert K into -OR1, (c) and when Y is <FORM:0917948/IV (b)/6> treating with sulphur or an oxidising agent, e.g. dinitrogen tetroxide to convert into <FORM:0917948/IV (b)/7> or <FORM:0917948/IV (b)/8> respectively.  The condensation in step (a) is preferably carried out in the presence of a solvent e.g. water, acetone, methyl ethyl ketone, or toluene and at between 0 DEG C. and 100 DEG C.  The phosphorothioate products may be converted to the corresponding phosphates by treating with various oxidising agents, thus O,O-diethyl-p-sulphamoylphenyl phosphorothioate may be treated with nitric acid at below 20 DEG C. to form the corresponding phosphate.  Several examples are given including the production of O,O-dimethyl-O-p-sulphamoylphenyl phosphorothioate by first reacting the sodium salt of 1-phenol-4-sulphonamide with thiophosphoryl chloride in the presence of a small amount of phosphorus trichloride to form O-p-sulphamoylphenyl phosphorodichloridothioate and then reacting the latter with two equivalents of methanol in the presence of triethylamine.  The products have insecticidal and parasiticidal properties (see Group VI).ALSO:An insecticidal composition, or a parasiticidal composition suitable for oral or parenteral administration to warm-blooded animals, contains as active ingredient a sulphamoylphenyl phosphate or thiophosphate having the formula <FORM:0917948/VI/1> wherein each R1 is the same or different and is a C1-C4 alkyl radical, A is an oxygen or sulphur atom and each R2 is the same or different and is a hydrogen atom or a C1-C6 alkyl radical (see Group IV (b)).  When the composition is to be adminstered orally it may be in the form of a capsule or tablet or it may be administered as a drench or by incorporation in feed, salt, or drinking water.  It may also be in the form of a solution, emulsion, suspension or wettable powder. Specified carriers are talc, clays, diatomaceous earth, attapulgus clay, fuller's earth, pyrophyllite and acetone.

Title: Electrolytic titrator
IPC: G01N27/44
Filed: 1965-04-30
Abstract: 1,098,992. Electro-physical measurement. INTERNATIONAL STANDARD ELECTRIC CORPORATION. April 30, 1965 [May 4, 1964], No.18248/65. Heading G1N. Continuous automatic titration apparatus, for monitoring noxious vapours e. g. sulphur or hydrazine compounds from propellants, and which electrolytically generates its own titrating agent, comprises a three electrode cell 10 through which gas (e. g. air) to be monitored is bubbled. The sensing electrode S is maintained at a small negative P. D. (below 1À1 volts to avoid hydrogen generation); the generating electrode G is connected to the positive supply, and the reference electrode R through a controlled switch to the negative supply, so that using e.g. hydrobromic acid as the electrolyte, bromine is generated at the generator electrode G increasing the conductivity between electrodes S, G, so that the control signal is reduced and the switching circuit disconnects the supply to electrode R. As bromine is used up, voltage across electrodes S, G, increases to energize the switch and complete the R, G, circuit. In practice the circuit cycles rapidly producing a series of current pulses in the RG circuit Fig. 3 (not shown) whose average value indicates the concentration of the noxious substance. A transistor switching circuit, with ganged range charging switches and a mains/battery power-pack is illustrated in Fig. 2 (not shown). Alternative cell constructions are illustrated in Figs. 4... 6 (not shown) each comprising a container with a vertical tubular cell having the electrodes S, G, R arranged one above the other (S at the top). The gas to be monitored is bubbled in at the bottom of the cell tube, and circulates the electrolyte as it rises. In Fig. 4 the bubbler comprises a conical, wettable glass frit (45) and circulation of the electrolyte from the outer container is restricted by a flow limiting pin (75) in an orifice at the bottom of the cell tube. In Fig. 6 a long spiral sensor electrode (154) is used to increase sensitivity and the electrolyte especially for hydrazine may be 3% potassium bromide, 5% sodium citrate, and 1% citric acid.

IPC: B23K11/30
Filed: 1926-07-28
Abstract: 257,581. Lawson, J. F. Aug. 27, 1925, [Convention date]. Collectors.-In an electric welding machine, particularly for welding tubes, current is conducted by an electrically conducting liquid, such as mercury, supplied to a crevice between a stationary member and a rotating member consisting of a roller electrode or a part connected thereto. Each electrode 15, which may be formed in one piece, or, as shown in Fig, 1, may consist of a copper disc 15 connected to an insulating disc 18 or to metal disc insulated therefrom, is connected by insulated bolts 21 to a ring 23 screwed to a collar 22 on a shaft 10. Current is conducted from the transformer terminals 34 by water-cooled stationary members 36, which are separated from the electrodes by a narrow crevice 41 to which mercury &c. is supplied on which the members rest by their own weight. The members rest on pins 50 on which the electrodes turn and are prevented from rotating by crossbars 52 fixed to the machine. The mercury is contained in wells 44 formed at the bottom of the members 36 and is raised to the top of the crevices by cavities 46 in the electrodes from which it is discharged into the crevices. Escape of mercury is prevented by gaskets 42 on the members 36 engaging grooves in the electrodes. The electrodes 56, Fig. 5, may be separated by an insulating plate 59 and connected by insulated bolts 58 to members 57, which are separated by crevices from stationary members 73 connected to the transformer terminals 74. Wells 80 in the members 73 have lips 81 engaging grooves 82 to the members 57 and the mercury is raised therefrom bv chambers 83 on the members 57 which are closed by perforated plugs 84, 84<a>, of which the plugs 84 have perforations 85 for outlet of mercury to the tops of the crevices. The outer walls of the chambers are screwthreaded at 88 to convey any mercury adhering thereto to the crevices, and gaskets 77 prevent escape of mercury from the crevices. The members 73 are bolted to and insulated from the journal boxes 69.
