Title: Improvements in or relating to processes for the preparation of phosphorus-containing heterocyclic compounds
IPC: C07F9/655
Filed: 1960-02-19
Abstract: The invention comprises compounds of the general formula: <FORM:0947156/C2/1> in which Q is the residue of a compound QH having a cyclic oxygen-containing heterocyclic nucleus including one carbon atom carrying a double-bonded oxygen atom, X1 is oxygen or sulphur, X2 is oxygen or sulphur, R1, R2, R3 and R4 each represent a C1-C6 alkyl group and X1 is bound to a carbon atom in the heterocyclic nucleus of Q. They may be obtained by reacting a compound QX1H preferably in the presence of a halogen hydracid binding agent or a compound QX1M in which Q and X1 are as defined above and M is a metal atom, e.g. Na or K, with a compound of the formula: <FORM:0947156/C2/2> wherein Hlg is a halogen atom preferably Cl and Y1 and Y2 both represent halogen, preferably Cl atoms or represent the groups NR1R2 and NR3R4 respectively wherein R1, R2, R3\t and R4 are as defined above and n is one or zero.  When Y1 and Y2 are halogen atoms the resulting product is reacted with an appropriate alkylamine, and when n is zero the tervalent phosphorus is converted to the pentavalent state in the amidated intermediate product by oxidation with hydrogen peroxide if X2 is to represent oxygen or by reaction with elemental sulphur if X2 is to represent sulphur. Specified halogen-hydracid binding agents are amines, especially tertiary amines including pyridine and its homologues, metal salts of weak acids and alkaline compounds of Na, K, Mg, Ca, Ba or Zn.  The reaction is preferably carried out in the presence of a solvent, e.g. an aliphatic or aromatic hydrocarbon, an ether, tertiary amine, nitrile, ketone, ester, nitrobenzene or carbon tetrachloride.  Q may suitably be the radical of tetronic acid, 1,2-pyrone, 1,4-benzopyrone, 1,2-benzopyrone or 2,3-benzopyrone and the heterocyclic nucleus of Q may be substituted e.g. by alkyl or alkoxy groups. R1, R2, R3 and R4 are preferably methyl groups.  The products have pesticidal properties. (see Division A5). Specificacations 713,278 and 940,921 are referred to.ALSO:A pesticidal composition contains as active ingredient a compound of the general formula <FORM:0947156/A5-A6/1> in which Q is the residue of a compound QH having a cyclic oxygen-containing heterocyclic nucleus including one carbon atom carrying a double bonded oxygen atom, X1 is oxygen or sulphur, X2 is oxygen or sulphur, R1, R2, R3 and R4 each represent a C1-C6 alkyl group and X1 is bound to a carbon atom in the heterocyclic nucleus of Q (see Division C2).  Q may suitably be the radical of tetronic acid, 1,2-pyrone, or 1,2-, 2,3-, or 1,4-benzopyrone and the heterocyclic nucleus of Q may be substituted, e.g. by alkyl or alkoxy groups.

Title: Improvements in means for and methods of forming mosaic electrodes for use in electric discharge tubes
IPC: H01J40/06
Filed: 1936-03-02
Abstract: 471,359. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. March 2, 1936, No. 6255. Convention date, March 13, 1935. [Class 39 (i)] A mosaic photo - electric cathode is formed by providing a roughened insulating surface on to which silver is deposited from a point source, a caesium coating being applied after the silver has been oxidized. To provide the roughened surface a mica plate may be scored or powdered quartz is blown in suspension' on to a mica plate 1, Fig. 1, provided with a " side mask so that only the centre square 2 has the quartz surface; the plate is now mounted on a metal backing 4, in an envelope 11, Fig. 1, containing a chamber 14 with a small orifice and with a deposit 17 of silver. A surrounding coil 19 is used to vaporize the silver after the envelope has been evacuated, and a discharge may be caused to take place between the chamber 14 and plate 1 to direct the vaporized silver in substantially straight lines on to the plate. The smooth part of the plate receives a uniform silver deposit ; the quartz particles, owing to their uneven form, receive the silver deposit 17, Fig. 4, on the outer parts only, shading the deposit adjacent the mica foundation and thereby forming discrete islands of silver deposit. When the plate is sufficiently coated, the envelope is broken along the line 20 and the end with the coated plate 1 is used to form part of a discharge tube 21 ; the discharge tube has a pipe 26 in connection with an exhausting tube 25, and a caesium supply 27. After exhaustion, oxygen is admitted to oxidize the silver deposit, this taking place in the presence of a glow discharge obtained by a coil 19; the caesium is then vaporized into the tube 21, the connection 10 to the smooth silver deposit on the outer edge of the plate 1 being used to test sensitivity of the photo-electric surface during processing, the surface being illuminated for this purpose.
