Title: Improvements concerning ester mixtures
IPC: C10L1/18
Filed: 1955-05-13
Abstract: An internal combustion engine fuel comprises a liquid hydrocarbon and a minor proportion of a hydrocarbon-soluble mixture of one or more neutral esters of a polycarboxylic acid and of one or more neutral esters of a phosphonic acid.  The presence of the hydrocarbon-soluble mixture protects the exposed engine parts against corrosion and incrustation and thus prevents premature wear.  The hydrocarbon-soluble mixture may also be added to mineral lubricating oils, since it influences the sliding properties of such lubricating oils and their ability to withstand pressure.  Polycarboxylic acids whose esters may be employed are phthalic, iso- or tere-phthalic, naphthalene or diphenyl carboxylic, and trimellitic acids and the halogen substitution products of such acids; also adipic, pimelic, suberic, azelaic, sebacic, nonane dicarboxylic, decane dicarboxylic, hexahydrophthalic, and alkyl-naphthalene dicarboxylic acids.  The phosphonic acids whose esters may be employed are benzene phosphonic, toluene phosphonic, xylene phosphonic (ethylbenzene) phosphonic, naphthalene phosphonic, alkyl-naphthalene phosphonic, cyclohexane phosphonic, indene phosphonic, dodecane phosphonic, di (chlorophenyl) phosphonic [also known as di (chlorophenyl) phosphinic], di (fluorophenyl) phosphonic and di (tolyl) phosphonic acids, as well as phosphonic acids which are substituted by radicles of petroleum fractions.  The alcohols from which the esters may be derived include C1-C10 alkanols, stearyl alcohol and cyclohexanol.  The esters may first be dissolved in mineral oil (e.g. spindle oil) and the solution added to the fuel.  If desired, basic compounds, particularly amines, can also be added to the fuels or lubricating oils.  In the examples, fuels are described consisting of benzine and (1) di (p-chloro- or fluoro-phenyl) phosphonic acid-n-butyl ester, dibutyl phthalate and spindle oil; (2) di (p-chloro-phenyl) phosphonic acid-n-butyl ester, p-chlorobenzene phosphonic acid di-n-butyl ester, methyl n-amyl adipate or methyl n-butyl terephthalate, gas oil and tetraethyl lead; and (3) p-chlorobenzene phosphonic acid distearyl ester, di-n-butyl sebacate, mineral lubricating oil and dicyclohexyl amine.  A fuel consisting of diesel fuel, p-chlorobenzene phosphonic acid di-n-butyl ester, methyl n-butyl phthalate and stearylamine is also described. Furthermore, a lubricant consisting of mineral lubricating oil, p-chlorobenzene phosphonic acid di-n-butyl ester, di-n-butyl sebacate or phthalate and dicyclohexyl amine or propoxy-n-butyl amine is described.

Title: Improvements in means for testing faulty electric line insulators and indicating leakage therein
IPC: G01R31/00
Filed: 1923-05-30
Abstract: 219,449. Brain, O. W. May 30, 1923. Detecting, indicating and locating faults.- Leakage from line insulators 12, Fig. 2, is indicated by a gravity drop indicator 41 supported by a releaser 22 located in the path of the leak current. The releaser, as shown in section in Fig. 1, comprises a cylindrical metal case 22 open at the bottom end, into which a porcelain plug 24 is secured by cement 27. Through the centre of the plug 24 is inserted a metal pin 29 having an eye 32 at the lower end. Into the upper part of the case 22 is inserted a paper cartridge 37 containing explosive 38 and closed by a carbon block 39. Pressed against the upper end of the cartridge 37 by a spring 40 is a carbon block 36, varnished paper sleeves 34, 35 insulating the powder charge 38 from the case 22. The pins supporting the insulators 12, Fig. 1, on each pole are connected together by a wire 17. The metal arm 41 is attached to the post by an insulated pivot 42, and is attached at its outer end to the lower eye 32 of the releaser, which is hung by its upper eye 21 from the pin 19 of one of the insulators 12. The arm 41 is connected to an earth wire 14 supported on insulators 13, a choking coil 47 being preferably inserted to prevent surges from passing through the releaser. On the occurrence of abnormal leakage, the cartridge 37 is punctured and the charge 38 exploded, forcing out the plug 24 and releasing the arm 41, which may make contact with a signal wire 45, by which an alarm is given at the station and the approximate location of the fault may be determined. The releaser may alternatively be operated by any substance operated by the heating effect of the! current. In a modification the explosive is contained within a glass or porcelain casing within which the pin is secured, the casing being broken on operation of the device. When the normal leakage current is of the order of a milli-ampere, a high resistance 48 may be connected between the wire 17 and the earth wire 14. The device may be employed for the protection of transformers &c.

IPC: H03C1/36
Filed: 1965-04-05
Abstract: 1,137,919. Amplitude modulated. MARCONI CO. Ltd. 1 Feb., 1966 [5 April, 1965], No. 14358/65. Heading H3R. An amplitude modulating arrangement comprising a transistor carrier oscillator 1, a modulating circuit including input and output transformers 8, 9 and diodes 10, 11, the impedance of which is varied by the modulating voltage and means for compensating for the effect on the oscillator of changes produced in its load by variations of the modulating voltage. In the positive modulation circuit shown the diodes are biased by the Zener diode 13 to permit passage of only a small carrier signal in the absence of modulation. The modulating signal applied via terminal 15 and emitter follower transistor 16 to point X opposes this bias and varies the impedance presented by the circuit. The modulating voltage is also applied from point Y via variable resistor 17 and Zener diode 18 to the emitter of the carrier oscillator and has the effect of increasing the H.T. supply to the oscillator as its load increases and hence maintains the voltage across the oscillator tank circuit substantially constant.
