Title: A new thionophosphoric acid ester
Inventor: SCHRADER GERHARD
IPC: A01N57/14
Filed: 1964-02-21
Abstract: The invention comprises O,O-dimethyl-thionophosphoric acid-O-(3-nitro-phenyl) ester.  The ester may be obtained by reacting an O,O-dimethyl phosphoric acid halide with 3-nitro-phenol preferably in the presence of an acid-binding agent, e.g. an alkali metal carbonate or alcoholate or a tertiary amine, e.g. dimethylaniline, triethylamine or pyridine. Alternatively, a salt, e.g. an alkali metal or ammonium salt of 3-nitrophenol may first be formed and then reacted with the O,O-dimethyl thiophosphoric acid halide.  The reaction is preferably carried out in an inert organic solvent, e.g. an aliphatic ketone, a nitrile, or dimethyl formamide and preferred reaction temperatures are from 30 DEG  to 80 DEG  C.  The product has pesticidal properties (see Division A5).ALSO:A pesticidal composition comprises a solid or liquid carrier or diluent and a phosphorus ester of the formula <FORM:0995959/A5-A6/1> (see Division C2).  Specified carriers or diluents are talc, chalk, bentonite, clay water (if necessary with an emulsifier), ketones and liquid hydrocarbons. Known insecticides and/or fertilizers may also be present.  A suitable composition is obtained by mixing the active ingredient with dimethyl formamide adding benzyl hydroxy diphenyl polyglycol ether as emulsifier and then diluting with water.

Abstract: 631,974. Pressure-regulating valves. TRIGGS, W. W. (Cash Co., A. W.). March 18, 1947, No. 7492. [Class 135] A pressure-regulating valve comprises a control pressure chamber 11 with an inlet 18 and an outlet 17, a guide sleeve 26 in the outlet, and a bush 19 in the inlet, both guiding an axially-slidable tube 28 which connects the inlet and outlet, a valve-member 30 supported radially in the tube to provide a flow passage of annular cross-section, and a pressureresponsive device connected to slide the tube 28. The pressure-responsive device comprises a spring-loaded diaphragm 12 with a stud 36 attached thereto and extending into the chamber 11, the stud having a nut 37 and a washer 38 at its end.

Abstract: 268,332. Muller, J. March 23, 1926, [Convention date]. Single-acting piston pumps; plungers; suction reservoirs; valves, arrangement of.-A lubricating pump comprises a barrel 5 connected by a conduit 6 to a chamber 8 containing a flexible container 38 of lubricant pressed upwards by a spring- actuated piston 14. During the suction stroke of the plunger 28 the lubricant enters the barrel through the valve 23. The plunger is of smaller cross-section than the barrel to enable the lubricant to enter the barrel as soon as the suction stroke begins. The lubricant is delivered through a valve 36 to a coupling. In the Specification as open to inspection under Sect. 91 (3) (a) a coupling is described comprising a body 45 provided with two communicating passages 46, 47, of which the former is connected to the pump, while the latter is open to the receiver 59. A pair of pivoted hooks 57 are deflected at their ends 60 by the intervening hand 58 of the receiver, and their other ends 61 push down a piston 48 and spring 55, and force a packing washer 52 against the head 68. When the lubricant enters the coupling, it forces up the piston 48 and turns the hooks 57 into tight contact with the head 58. This subject-matter does not appear in the Specification as accepted.

Title: Antimicrobial agent mí¬188, its salts and method of preparation
IPC: C07G11/00
Filed: 1961-03-01
Abstract: Antimicrobial agent M-188 is produced by cultivating an antimicrobial agent M-188-producing strain of Streptomyces caelestis under aerobic conditions in an aqueous culture medium containing assimilable sources of carbohydrate, nitrogen and inorganic salts.  Preferably cultivation is carried out at 20 DEG -32 DEG C. for 2 to 6 days under submerged aerobic conditions.  The culture medium may also contain a source of growth substances, an insoluble buffering agent and a non-toxic defoaming agent.  The antimicrobial agent M-188 is separated by (a) filtering the whole culture broth and extracting the solid phase with acetone or an alcohol in which the antimicrobial agent is soluble or (b) acidifying the whole broth and filtering. The filtrate of (a) and (b) is preferably adjusted to pH 8-10 and then extracted with a water-immiscible polar organic solvent, e.g. chloroform or ethyl or amyl acetate.  The organic solvent extract may then be evaporated to dryness or extracted into dilute aqueous acid. The acid extract is then made alkaline, e.g. with sodium hydroxide to precipitate the antimicrobial agent M-188 as free base.  The base is purified by chromatography or by passing a chloroform solution thereof over magnesium silicate and eluting with chloroform containing ethanol.  Antimicrobial agent M-188 is a base forming salts with acids, e.g. hydrochloric acid, oxalic acid, salicyclic acid, benzoic acid, sulphuric acid, or citric acid in water or organic solvent solution.  Antimicrobial agent M-188 is soluble in methanol, ethanol, chloroform, ethylacetate, benzene and water to the extent of 2,5 mg/ml at 25 DEG C., but insoluble in saturated hydrocarbons.  It has a U.V. maximum at 232mm  E1%1cm = 29; an I.R. spectrum as 279mm  E1%1cm = 280 and a minimum at shown in the drawing; [a]25D = -40 DEG  (1% in chloroform); an empirical formula C38H61NO14; elemental analysis C = 60,37%, H = 8,21%, N = 1,91% and O = 29,51%; MWt. = 756 and a Pka of 6,7 when filtrated in 50% aqueous ethanol.  Antimicrobial agent is used in treating turkey sinusitus and coccidioses and is administered in their feed such as chicken feed or by injection.  Specification 768,971 is referred to.

Title: Improvements relating to apparatus for gas analysis
Inventor: WOLFF HEINZ SIEGFRIED
IPC: G01N27/74
Filed: 1960-03-03
Abstract: 984,560. Magnetic tests. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 2, 1961 [March 3, 1960], No. 7584/60. Heading G1N. A gas analyser for determining the concentration of a gas in a gas mixture, by utilizing the property of magnetic susceptibility of the gas, comprises a chamber 1, Fig. 1, surrounded by an electromagnet having a coil 6 and polepieces 3, 4 and being capable of producing a strong field through the chamber in its axial direction. The chamber is divided into two compartments by a pressure responsive diaphragm 7 provided with a thin conductive coating which co-operates with a fixed electrode 8 located in the lower compartment, to form a condenser. As described for oxygen analysis purposes, the inlet 9 to the upper compartment is connected to a reservoir of the oxygen containing gas to be analysed and the inlet 10 to the lower compartment is connected to a reservoir of a gas, e.g. nitrogen, or a gas mixture of negligible magnetic susceptibility as compared with that of oxygen. When a strong fluctuating field is produced, a force is exerted on the diaphragm 7 due to the variation of pressure produced by the oxygen under the influence of the field, this force being proportional to the difference in volume susceptibility of the gases in the two compartments and therefore proportional to the oxygen content of the gas in the upper compartment. The resulting pulsating deflection of the diaphragm 7 produces changes in the capacity of the condenser 7, 8 which, being connected in series with a resistance, brings about a voltage drop across the resistance that is a function of the oxygen concentration. To compensate for random variations in the intensity of the field, the output of the condenser 7, 8 is applied to a zero indicating amplifier 15, Fig. 3, which is also connected in antiphase to a variable attenuator 16 supplied by a pick up coil 11 and a Hall-effect crystal 12 located in the lower compartment of the chamber 1. The fraction of the crystal output signal, as determined by the attenuator, which is required to zeroize the amplifier, is a function of the required susceptibility difference, independently of the magnitude of the field. Alternatively, the field may be stabilized by regulating the source of supply of the electromagnet. The apparatus may be employed for the analysis of a continuously flowing gas mixture. The movement of the diaphragm 7 may alternatively be detected by optical methods.
