Title: Thiophosphoric acid esters
IPC: C07F9/165
Filed: 1958-06-04
Abstract: The invention comprises thiophosphoric acid esters of the formula: <FORM:0850984/IV(b)/1> wherein R, R1 and R2 are C1-C4 alkyl radicals and R3 is hydrogen or a C1-C4 alkyl radical and wherein R1 and R2 may also form a ring system, e.g. piperidine or morpholine, with the nitrogen atom, and Z is oxygen or sulphur.  They may be obtained by reacting a haloalkyl sulphonic acid dialkylamide of the formula: Hal,CH2,CH(R3),SO2,N(R1)(R2) with an appropriate dialkylthiol- or dialkyl thionothiol-phosphoric acid, the acid being either free in which case the reaction is carried out in the presence of an acid binding agent, or being in the form of a salt, e.g. the sodium or ammonium salt.  The reaction may be effected in an inert organic solvent, e.g. an alcohol, aliphatic ketone or aromatic hydrocarbon, and suitable reaction temperatures are between room temperature and the boiling point of the solvent used.  Examples are given for the production of compounds in which Z is sulphur, each R is ethyl, R3 is hydrogen and N(R1)(R2) is N(CH3)2, piperidino, and morpholino and of the compounds of the formula (C2H5O)2P(O)SCH2,CH2, SO2N(CH3)2, (C2H5O)2P(S)S,CH2,CH(CH3) SO2 N(CH3)2, (CH3O)2P(S)SCH2 CH2SO2N(CH3)2, ((CH3)2CHO)2P(S)S,CH2,CH2 ,SO2N(CH3)2 and the corresponding thiolo phosphoric acid derivative, and ((CH3)2CHO)2P(S)SCH2CH2,SO2N (C2H5)2. The products are useful as insecticide (see Group VI).  Starting materials: Cl,CH2CH2,S,N(CH3)2 is obtained by reacting b -chlorethyl sulphenic acid chloride with dimethylamine and is then treated with potassium permanganate in the presence of magnesium sulphate and acetone to form the compound Cl,CH2,CH2,SO2N(CH3)2.  The latter on treatment with sodium iodide in methyl ethyl ketone at 80 DEG  C followed by the oxidation of acetone yields I,CH2,CH2,CH2,SO2N(CH3) 2.ALSO:An insecticidal composition comprises as active ingredient one or more thiophosphoric acid esters of the formula <FORM:0850984/VI/1> wherein R, R1 and R2 are C1-C4 alkyl, or R1 and R2 may form a ring system, e.g. piperidine or morpholine, with the nitrogen atom, R3 is hydrogen or C1-C4 alkyl, and Z is oxygen or sulphur (see Group IV(b)) and a solid or liquid carrier or diluent. Specified carriers are talc, chalk, bentonite, clay, water (if desired with an emulsifier e.g. benzyl hydroxy diphenyl polyglycol ether), dimethyl formamide, alcohols ketones, and liquid hydrocarbons. The active ingredient may be used in conjunction with known insecticides and/or fertilisers.  Typical active ingredients are <FORM:0850984/VI/2> and the corresponding 0,0-diisopropyl dithiophosphate.

Patent GB-530350-A (GB)
Title: Improvements in echo-sounding systems
IPC: G04F10/10
Filed: 1939-06-22
Abstract: 530,350. Echo-sounding apparatus. ATLAS-WERKE AKT.-GES. June 22, 1939, No. 18163. Convention date, July 8, 1938. [Class 118 (ii)] In arrangements in which the depth indication is maintained until the next echo arrives and therefore might persist after failure of the apparatus to respond to echoes, an electric circuit is dependent on the receipt of echoes so that after prolonged or repeated non-receipt it disconnects the indicator or brings about a special indication, which is preferably given by moving the pointer to the higher end of the scale. In the arrangement shown, sounds are emitted at 3 under control of a rotating cam 1 and the echoes are received at 4 and applied after amplification to the grid of a valve 7 in the discharge circuit of a condenser 8 which includes also relays 12, 18. When relay 12 operates, a switch arm 13 rotating in synchronism with the cam 1 over contacts 15 at progressively higher voltages is connected to the voltmeter 11 to indicate the depth, a condenser 17 in parallel being charged to maintain the reading. At the same time, relay 18 swings over its contact 19, opening the receiving circuit to prevent any effect from repeat echoes, and discharging a condenser 27. The contact 19 is restored by a second winding 20 of the relay at the next sound emission. The condenser 27 is constantly charging, and if the discharge circuit over contact 19 is not made for a predetermined number of echoes, e.g., three, a discharge tube 30 breaks down and relay 25 operates, applying a high voltage to bring the pointer of the voltmeter to the sector 26. At each emission, a condenser 44 which is connected to the grid of the valve 7 is charged by the action of a cam 43 and is then allowed to discharge and reduce the negative bias, so that the sensitivity gradually increases from a point at which it fails to respond to direct sound from the emitter 3. Disconnection of the condenser 44 by a switch 23 allows the observer to test that the apparatus is in order. In one modification, the indicating circuit is broken at contacts controlled by a cam just before each emission if the echo from the previous emission has not arrived, that is, if contact 19 is unoperated.

Air passes from the pipe 10 through 44 in the tube 35 when the cars are coupled. When the cars are uncoupled a valve member 34a formed on the end of the tube 35 is forced on to a conical seat 33a by a spring (not shown). An aperture 42 is provided-so that the brakes are applied gradually when uncoupling occurs.

Abstract: 357,144. Copying-telegraphy. HARRIES, J. H. O., Shirley, Old Road, Frinton-on-Sea. June 16, 1930, No. 18359. [Class 40 (iii).] In copying telegraphy, the centre of interest of the picture is scanned more finely than the remainder. The picture drum 1, Fig. 1, is rotated and the scanning device 2 is traversed by a lead screw of which the centre portion 4 has a finer thread that the outer portion 3. Gearing 5, 6 allows the lead screw to be adjusted so that the finely-scanned area may be adjusted over the picture. The drum 1, Figs. 2 and 3, is driven by an eccentric cam 10 driven by a pinion 8 from a constantly-rotating gear 9. This arrangement allows the drum to be more slowly rotated over one portion. Adjustment of the position of the pinion 8 is effected by gearing 13, 14. In order to adjust the scanning spot, an iris diaphragm 15, Fig. 4, is closed or opened under the action of a cam arm 17 moving in a cam slot 19, so that the beam of light 16 is suitably adjusted. Specification 357,143 is referred to.
