Title: Electrical devices for testing the surface deviations and errors of shape of nominally round workpieces
IPC: G01B7/34
Filed: 1959-07-10
Abstract: 929,943. Measuring linear dimensions electrically. J. PERTHEN. July 10, 1959 [July 11, 1958], No. 23778/59. Class 40 (1). Apparatus for measuring electrically the inaccuracies in shape of a nominally round workpiece by means of a probe rotating relatively to the workpiece, incorporates means for adding to the voltage signal a correction to compensate fur errors in centring and alignment between the probe and the workpiece. It is shown that the errors comprise linear and square sinusoidal quantities. In one embodiment (Fig. 2) the surface shape of a test body 1, driven by a motor 5, is sensed by an electrical probe 16. A synchronously driven, perfectly round body 25 with preset eccentricity, is sensed by two perpendicular probes 26, 27 whose outputs are mixed in appropriate proportions to provide the linear correcting quantity, and squared to provide the other correcting quantity, the appropriate proportions being ascertained by the attainment of a concentric circle on the screen of a cathoderay oscillograph 21, and a zero average reading on a meter 20. Alternatively, the probes 26, 27 may be fixed, and the eccentricity of the master body 25 adjusted by perpendicular screws (Fig. 1, not shown), or the combination 25, 26, 27 may be replaced by a synchronous A.C. generator giving two quadrature outputs. The quadrature components may be adjusted automatically using switches controlled by quadrature cams, whereby the output signal variations due to eccentricity are fed to quadrature motors which automatically adjust the quadrature components, mechanical or electrical, to elimate eccentricity errors.

Title: New thiophí¡í¡ esters
IPC: C07F9/165
Filed: 1960-07-07
Abstract: The invention comprises thiophosphoric esters of the formula (CH3O)2P(X)SCH2CH2 SCH(CH3)CONHCH3 wherein X is an oxygen atom or a sulphur atom.  They may be obtained (a) by reacting a halogeno phosphate of the formula (CH3O)2P(X1)Hal with a compound of the formula HX2.CH2.CH2.S.CH(CH3) CONHCH3 or with a salt thereof, where X1 and X2 are both sulphur atoms or one of X1 and X2 is an oxygen atom and the other is a sulphur atom and Hal is a halogen atom preferably chlorine, (b) by reacting a salt, e.g. an alkali metal or ammonium salt, of an O,O-dimethylthio (or dithio) phosphoric acid with a reactive ester of the formula Y.CH2. CH2.SCH(CH3)CONHCH3 where Y is the acid residue of a reactive ester, e.g. a halogen atom, or a sulphuric or sulphonic ester group, or (c) by reacting a reactive ester (e.g. a halide) of an O,O-dimethylthio(or dithio)phosphoryl-2-ethanol with the compound HS.CH(CH3) CONHCH3 or with a salt thereof.  Method (a) is preferably carried out in a solvent medium at below 150 DEG C. in the presence of a basic condensing agent, e.g. an alkali metal or its hydroxide or carbonate. The reaction may be effected without the condensing agent when the second mentioned reactant is used in the form of an alkali metal salt.  Suitable solvents are aliphatic alcohols and ketones and chlorinated hydrocarbons.  Methods (b) and (c) are preferably carried out in water or an organic solvent, e.g. an aliphatic alcohol or nitrile, or a ketone, at between 15 and 150 DEG C., e.g. at the boiling point of the solvent used.  Examples are given for the production of the O,O-dimethylthiolo(and dithio)phosphoryl compounds using method (a).  The products have pesticidal properties (see Group VI).ALSO:A pesticidal composition comprises at least one phosphorus ester of the formula <FORM:0924821/VI/1> wherein X is an oxygen atom or a sulphur atom (see Group IV (b)) together with at least one diluent compatible therewith. Specified diluents include talc, calcined magnesia, kieselguhr, tricalcium phosphate, powdered cork, absorbent carbon black, kaolin, bentonite, aromatic hydrocarbons e.g. toluene or xylene, and mineral, animal or vegetable oils.  The compositions may be in the form of aerosols, suspensions, emulsions, or solutions in organic or aqueous organic media and may contain wetting, dispersing or emulsifying agents of the ionic or non-ionic type such as sulphoricinoleates quaternary ammonium compounds, ethylene oxide condensates e.g. with octyl phenol or fatty acid esters of anhydrosorbitols condensed with ethylene oxide.  Other pesticides may also be present.

Title: Improvements in the manufacture of thermionic cathodes for electric discharge devices

Abstract: 378,651. Thermionic cathodes. M-O VALVE CO., Ltd., Marconi House, Strand, London, ALDOUS, W. H. and JACKSON, J. F., of General Electric Co., Wembley, Middlesex. Aug. 25, 1931, No. 23925. [Class 39 (i).] A mixture containing alkaline-earth carbonate is sintered so as to increase greatly the mean size of the carbonate particles, e.g. from 1 Á. to 120 Á., and is then applied to the cathode core. In one example equal weights of precipitated barium carbonate and strontium carbonate are mixed, placed in a nickel boat, heated for 10 minutes to a temperature of 1100‹ C. in a stream of carbon dioxide, and cooled while still in the gas. The mass is mixed in a ball mill, heated for 70 minutes, and cooled as before. The mass is then ball-milled for 5 minutes and particles over 120 Á. in diameter sifted out and crushed. The mixture may then be suspended in a binding medium, coated on the cathode core, and reduced to the oxide in the usual way.

Title: Methods and means for determining the velocity with which a fluid medium flows past a body or with which a body moves in a medium
IPC: G01S1/72
Filed: 1920-08-18
Abstract: 150,289. Atlas - Werke Akt. - Ges. Aug. 18, 1919, [Convention date]. Anemometers.-A source of sound such as a bell C is arranged between two sound-receiving funnels A, B connected by pipes R<1>, R<2> to earpieces O<1>, O<2>. A relative velocity of the medium along the line AB will, if the apparatus is symmetrically arranged, produce a difference between the arrival of the sound at the funnels A, B; this produces in the observer the impression that the source of sound is situated to one side of him. The adjustment, such as an alteration of the length of the tube R<1> or a movement of the source of sound between the funnels, required to make the sound appear central, gives a measure of the velocity relative to the medium. The apparatus may be adjustable about a vertical axis. Two pairs of funnels at right-angles may be used.

[Class 40 (vi)] [Also in Groups XXXIX and XL (b)] The duration of an electric signal is transformed without change in amplitude by applying it to an artificial line AB having a characteristic time-delay T and charging individual sections of a second artificial line CD, e.g. through valves V, under the control of individual sections of the line AB after a time interval T, the second line CD having a different characteristic time-delay T<1> and being arranged to discharge into a load circuit at Z<1> for a time interval T<1>. The sections of the line AB cause the corresponding sections of CD to be charged proportionally through valves V, all of which are cut-off except when a short positive pulse is applied simultaneously to all the control grids at intervals T. Fivechannel transmission on a 2 megacycle band is achieved by charging CD, having T<1>=5 microseconds, under the control of five separate lines AB, each having T=100 microseconds and each comprising six individual sections. Impedances Z, Z<1> stop reflection in the respective lines. Specification 434,882, 434,890, and 434,891 are referred to.
