Title: A process for preparing alkenes with at least five carbon atoms in the molecule and/or derivatives thereof
IPC: C07C11/02
Filed: 1935-01-03
Abstract: Alkenes having at least five carbon atoms and/or derivatives thereof, are obtained by cracking normally non-gaseous hydrocarbon mixtures, preferably in the vapour phase, refining the liquid products with selective solvents, whereby undesirable constituents are eliminated, and fractionally distilling the refined products, and/or converting the products into derivatives.  A preliminary fractional distillation of the cracked products may precede the refining step.  According to an example, filtering oil from mineral oil containing paraffin wax, is cracked, refined with furfurol, and treated with sulphuric acid at low temperature; alkyl sulphuric acid and an alcohol fraction were separated from the product.  Hydrocarbon mixtures from which the alkenes may also be obtained, include distillates or residues of mineral oils, tar oils, brown coal oils, paraffin gatch, paraffin wax and sweating oil and filtering oil.  Selective solvents specified also, include liquid SO2, alcohol-ether and nitrobenzene.  All derivatives may be produced, excluding lubricating oils from the alkenes, and those specified include also alkanes, ethers and esters. The Specification as open to inspection under Sect. 91 includes a refining treatment with chemical agents including sulphuric, nitric and chromic acid, aluminium chloride and boron fluoride, and refers to quinoline, isoquinoline, dichlorethyl ether and mixtures of these solvents with benzene and naphthalene, as further selective solvents. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in combinations of electric discharge devices with incandescent filaments in series with them
IPC: H01J61/96
Filed: 1938-01-06
Abstract: 499,540. Supply systems for discharge lamps. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. f³r Elektrische Gl³hlampen) Jan. 6, 1938, No. 418. [Class 38 (iv)] Emergency systems.-An electric discharge lamp is connected in series and structurally combined with a filament which is rendered incandescent by the discharge current and serves, at least in part, as a stabilizing resistance. The filament runs fully loaded or slightly over-loaded and means are provided whereby when the filament burns out it may be replaced,' preferably automatically. In the arrangement described, a substitute filament 8, in combination with devices 9 and 10 which break down under excess voltage, is connected in parallel with a filament 6 which normally functions in series with a H.P.M.V. lamp 1 across the supply terminals 7, 7<1>. The centre points of the filaments 6 and 8 are connected by a conductor 11 so that, as long as filament 6 remains intact, the maximum voltage across either of the devices 9 and 10 is a little less than half the mains voltage and is insufficient to cause their breakdown. A high impedance 5 is connected across electrodes 2, 2<1> of. the lamp 1 so that when, say, the half of filament 6 nearer to 7 burns out, the device 9 is connected across the supply terminals by way of the impedance 5, the intact half of filament 6 and the half of filament 8 nearer to 9. The device 9 then breaks down under full mains voltage and operating conditions are restored with half of filament 8 replacing the broken half of filament 6. If the remaining half of filament 6 breaks, the device 10 will be broken down and the whole of filament 8 brought into operation. The devices 9 and 10 are composed of oxide film which breaks down at a critical voltage. Alternatively any known means of automatically replacing a damaged filament by a sound one may be employed. If the lamp 1 is one in which an outer jacket surrounds an envelope enclosing the discharge, the filaments and all or part of the means for substitution may be located in the space between the envelope and the jacket. More than one substitute filament may be used.

Title: Manufacture of anhydrous salts of mercaptobenzthiazole
Inventor: BROWN WILLIAM ALEXANDER FRASER
Filed: 1955-01-12
Abstract: Anhydrous water-soluble metal salts of mercaptobenzthiazole are obtained from their aqueous solutions by azeotropically distilling the solutions in the presence of an inert organic liquid. Water-soluble salts which may be prepared in an anhydrous form by this process include the sodium, potassium, calcium and magnesium salts.  Any inert liquid that forms an azeotrope with water may be used, e.g., toluene, xylene, chlorobenzene, diisobutylene, petroleum ether, cyclohexane, 1.2-dichloropropane, anisole, diisobutyl ether or ethyl isobutyl ketone.  Preferably the distillation is carried out in the presence of a surface active agent, for example, alkyl aryl sulphonates, sodium alkyl sulphates, petroleum sulphonates, alkyl naphthalene sulphonates, sulphated esters, or ethers or polyglycol ethers of alkylated phenols.  In the examples: (a) a mixture of the sodium salt of 2-mercaptobenzthiazole and sodium dodecylbenzene-sulphonate in water is added to toluene heated to refluxing in an azeotropic separation unit; the mixture is refluxed until the water is completely removed and the anhydrous sodium mercaptobenzthiazole may then be filtered from the toluene; and (b) sodium mercaptobenzthiazole solution is made by dissolving 2-mercaptobenzthiazole in sodium hydroxide solution and is azeotropically distilled in the presence of xylene until no more water separates; the anhydrous sodium salt is filtered off from the xylene.ALSO:Anhydrous water-soluble metal salts of mercaptobenzthiazole are obtained from their aqueous solutions by azeotropically distilling the solutions in the presence of an inert organic liquid.  Any inert organic liquid that forms an azeotrope with water may be used, for example, toluene, xylene, chlorobenzene, diiso-butylene petroleum ether cyclohexane, 1 : 2 - dichloropropane, anisole, di-isobutyl ether, and ethyl isobutyl ketone.  Preferably the distillation is performed in the presence of a surface active agent, for example alkyl aryl sulphonates, sodium alkyl sulphates, petroleum sulphonates, alkyl naphthalene sulphonates, sulphated esters or ethers, or polyglycol ethers of alkylated phenols.  In the examples (a) an aqueous solution of the sodium salt of 2-mercaptobenzthiazole is azeotropically distilled in the presence of toluene and sodium dodecylbenzene sulphonate to give a slurry of the anhydrous salt in toluene; and (b) an aqueous solution of the sodium salt of 2-mercaptobenzthiazole is azeotropically distilled in the presence of xylene to give a slurry of the anhydrous salt in xylene.

Title: Arrangement for protecting telecommunication apparatuses from a voltage transient
Inventor: ATKINS IAN PAUL
IPC: H02H9/00
Filed: 1991-09-27
Abstract: An arrangement for protecting an electrical circuit such as a telephone circuit from a voltage transient comprises a voltage clamp or foldback device (3) arraigned to be connected between a current-carrying line (1) and ground (1'), a capacitor (2) in series with it, and an inductance (4) series connected in the line. During normal operation the arrangement acts as an LC filter whose high frequency break-point is determined by the capacitance of the voltage clamp or foldback device (3) and the value of the inductance (4) which are chosen to give a break point of 1 kHz to 10 MHz. However, when the arrangement is subjected to a voltage transient, the voltage clamp or foldback device (3) fires causing the break-point to fall to a value determined by the values of the capacitor (2) and inductance (4). The arrangement may be used, for example, to protect the circuit against a rapid voltage drop caused by the firing of another circuit protection device such as a gas discharge tube 5.

Title: Controlling method of returned quantity of sludge
Inventor: MACHIDA MASAMICHI
IPC: C02F3/12
Filed: 1979-01-08
Abstract: PURPOSE: To stably control the concentration of floating solids at a setpoint for a long time and obtain processed water of stabled good quanlity, by determining a target level for the returned quantity of sludge depending on the rate of change in the quantity of sewage introduced into an aeration vessel.  
     CONSTITUTION: The flow rate Qi of sewage introduced into an aeration vessel 2 from a passage 1 is measured by a detector 9. The measured value is always watched by a calculation controller 13. The controller discriminates the fluctuation in the flow rate Qi of the sewage to determine a returned sludge quantity control method to return deposited sludge from a final settling pond 4 to the aeration vessel 2 through a pump 7. When the rate of change in the quantity of the introduced sewage is larger than a setpoint, a target level is determined for a returned sludge quantity proportional to the quantity of the introduced sewage. When the rate of change is smaller than the setpoint, a target level is determined for a returned sludge quantity to make the concentration of floating solids in the aeration vessel 2 constant.
