Title: Improvements in or relating to anti-corrosion oils
IPC: C23F11/12
Filed: 1943-12-08
Abstract: Anti-corrosion compositions for use in displacing water, particularly sea water, from metal surfaces, and in protecting such surfaces, particularly iron, steel, copper, aluminium and brass surfaces, from corrosion, comprise major proportions of hydrocarbon oils having initial boiling points of not less than 50 DEG C. and final boiling points not exceeding 370 DEG C. and minor proportions of oil-soluble wetting agents, oily or fatty protective agents and spreading agents. The spreading agents are non-cyclic aliphatic alcohols containing from four to eight carbon atoms in the molecule, such as diacetone alcohol or butyl alcohol, while protective agents mentioned are heavy hydrocarbon oil, asphaltic bitumen, bright stocks with polar additives, lanolin, woolgrease which may be neutralized with oxides, hydroxides or carbonates of sodium, potassium, calcium or magnesium, and glycerides such as glyceryl mono-oleate.  Suitable wetting agents are the soaps of petroleum acids such as sodium naphtha sulphonates or the alkali salts of sulphated fatty alcohols such as the sodium salts of sulphated C8-C19 alcohols, and the hydrocarbon oils forming the basis of the composition may be petroleum naphtha, kerosine or white spirits.  In the examples, compositions are described consisting of (1) petroleum naphtha, sodium naphtha sulphonate, lanolin and diacetone alcohol, (2) petroleum naphtha, sodium naphtha sulphonate, soda-neutralized wool grease, glyceryl monooleate and diacetone alcohol and (3) kerosine sodium naphtha sulphonate, lanolin and diacetone alcohol.  The Provisional Specification mentions soaps of fatty acids, for example oleates as wetting agents, natural waxes and esters as protective agents and alcohols containing not more than 19 carbon atoms, for example methyl cyclohexanol, as spreading agents.  Specifications 442,653 and 523,520 are referred to.

Patent GB-1327673-A (GB)
Title: Apparatus for forming signals indicative of conditions on a  subscribers line
IPC: H04M3/24
Filed: 1971-04-19
Abstract: 1327673 Automatic exchange systems ZELLWEGER Ltd USTER FACTORIES FOR APPARATUS & MACHINES 19 April 1971 [9 Feb 1970] 20760/71 Heading H4K In order to distinguish for general monitoring purposes between dialling impulses, metering pulses and ringing current pulses on a subscriber line, the latter is connected to logic which distinguishes whether or not the line is looped thus identifying uniquely the case of ringing current pulses in the event that the line is unlooped and which measures in effect the magnitude of the pulses so as to distinguish the ease of dialling and metering in the event that the line is looped. The line 7 at its appearance 21, 22 on the MDF normally has its wires connected via contacts 8, 9 and windings 1, 2 of a line relay to battery so that in the unlooped condition of the line, terminals 21, 22 carry battery potential. When the line is looped terminals 21, 22 become respectively more negative, positive thereby altering the input potential to a low pass filter 30 whose output is digitized by amplifier 40 to provide a "line-looped" condition Ub. During dialling, the potential at terminals 21, 22 approaches the battery emf at each loop break so as to cause both of amplifiers 50, 60 to provide digital 0 outputs to NOR gate 67. The latter's output via monostable 77 opens gate 79 in conjunction with the line-loop criteria Ub so as to present a dialling impulse train signal Uw. The low pass filter 30 (pass level 5 c.p.s.) prevents the impulses from de-energizing the amplifier during their break portions. In order to ensure that the voltage output from filter 30 remains non-critical during dialling even on long lines, the output signal Uw is fed back additively via diode 104. Metering pulses occurring as 50 c/s pulses from a source 16 are applied to the line wires via transformers 5, 6 so that the digital outputs from amplifiers 50 60 are now always of opposite type. Consequently NOR gate 67 remains closed but AND gates 69, 71 are opened to deliver a signal via AND gate 88 to gate 94 which is opened by the line looped criteria Ub and thus provides a metering pulse signal Ut. Calling signals are applied as 25 c.p.s. pulses from source 14 to only one line wire but this produces the same effect from amplifiers 50, 60 as for metering pulses. In this case however the line is unlooped so that gate 92 is opened to provide a calling signal Ur. In an alternative arrangement, metering pulses may be applied to line as 12 Kc/s pulses from source 18. In this ease they are detected by a high pass filter 100 whose output is digitized by amplifier 101 to provide the alternative metering pulse signal U<SP>1</SP>t.

Title: Process and apparatus for the production of sodium aryls
IPC: C07C51/15
Filed: 1958-06-27
Abstract: Suspensions of sodium aryls are obtained by continuously mixing a suspension of sodium in an inert liquid and an aryl halide, passing the mixture through a flow vessel under regulated temperature conditions and allowing the reaction to complete in a second flow vessel of larger capacity than the first flow vessel. As shown a suspension of metallic sodium in say, benzene or toluene in a storage vessel 1 having stirring means, is fed by bailing device 2 through a conduit 3 into a reaction vessel <PICT:0875594/IV (b)/1> 4.  The reaction mixture is circulated by a propeller 5 and overflows by means of an overflow device 8 into a second reaction vessel 9.  The aryl halide (e.g. chlorobenzene) is introduced simultaneously via conduit 10 into the reaction vessel 4 using a second metering device 11.  Both reaction tubes 4 and 9 are jacketed (7) and the temperature of the reaction mixture is followed by thermometer 6, cooling or heating of the jackets being carried out as necessary.  The chlorobenzene or other aryl halide may be diluted with an inert liquid or if it is desired to metallise a compound having weakly acidic hydrogen atoms by means of the sodium aryl, this compound, together with an inert liquid if desired, may be mixed with the aryl halide.  The examples describe the preparation of 1) sodium phenyl and its subsequent carbonation to benzoic acid: 2) sodium-4-tolyl and toluic acid: 3) sodium phenyl and its reaction with benzaldehyde to give benzohydrol: 4) para-sodium anisole and its reaction with acetophenone to give paramethoxy phenyl-phenyl-methyl carbinol: 5) sodium phenyl which is converted to a -sodiocyclohexane carboxylic acid nitrile, and this product is reacted with 2-bromo-n-butane to give cyclohexane - sec. - butyl-carboxylic acid nitrile: and 6) sodium phenyl which is converted to diethyl-a -sodio-acetonitrile, which in its turn is reacted with benzyl chloride to give diethyl - benzyl - acetonitrile.

Filed: 1974-05-14
Abstract: 1434463 Flash-lamp control circuits INTERNATIONAL BUSINESS MACHINES CORP 14 May 1974 [26 June 1973] 21184/74 Heading H2H  A flash-lamp circuit has an energy storage supply device comprising a charging means having a plurality of impedance levels, the arrangement being such that substantial recharging of the storage device after initiation of a flash is inhibited until the flash-lamp becomes de-ionized. Assuming a capacitor 13 to be fully charged from a D.C. source 14 by way of a resistor 19 in parallel with a thyristor 17, the thyristor will be non- conductive. Flashing of a lamp 10 is initiated by a signal applied to a terminal 26. This signal renders conductive a thyristor 24 whereupon a capacitor 23, previously charged from a D.C. source 32, discharges through the primary winding of a transformer 27, the resulting pulse from the secondary winding ionizes the lamp 10, the capacitor 13 then discharging therethrough to produce a flash. The signal at terminal 26 to initiate the flashing of lamp 10 is also applied to a delay circuit 33 which after a delay, sufficient to allow the lamp 10 to de-ionise, energizes a circuit 34 which produces a signal to render conductive the thyristor 17 whereupon the capacitor 13 is rapidly recharged. The resistor 19 is given a high ohmic value so as to severely limit the current supplied to the capacitor 13 and lamp 10 from the source 14 during flashing of the lamp 10 which current is insufficient to prolong the flashing of the lamp.
