Patent GB-463742-A (GB)
Title: Improvements in the manufacture and production of motor fuel
IPC: C10L1/06
Filed: 1935-11-13
Abstract: Benzine, and other mixtures of hydrocarbons of similar boiling range, are separated into fractions having different octane values by extraction with acetonitrile, separating the layers and removing the solvent from the extract.  The benzine to be treated may first be separated into fractions of different boiling point and one or more of these extracted; the resulting extract of high octane value is then blended with the non-treated fractions or other hydrocarbons to form a motor fuel.  The solubility of acetonitrile in benzine may be reduced by addition of water, formamide or glycol.  In an example, benzine is split into a heavy fraction boiling above 130 DEG  C. and a light fraction.  Each fraction is extracted at room temperature with an equal amount of acetonitrile and the extracts, after removal of solvent by washing with water or distillation, are combined to form a motor fuel of octane number 86.  A part of the raffinate may be added.

Abstract: 910,091. Hydraulic transmission of power. VOITH G.m.b.H., J. M. Sept. 13, 1960 [Oct. 9, 1959], No. 31543/60. Class 69 (2). In a power transmission suitable for rail vehicles comprising at least two coaxial turbo transmitters I, II, Fig. 1, arranged adjacent one another, operating in the same direction of rotation, and being arranged to be cut in and out to provide different speed ranges, the impellers of the transmitters are mounted on a common primary shaft 4 which is driven by gearing 2, 3 disposed between the transmitters and is constructed in the form of a sleeve substantially enclosing a single secondary shaft 5 connected to the runners of the transmitters, the output being taken directly from and coaxial with the secondary shaft. The shaft 4 is driven by gearing 2, 3 from an input shaft 1 and the impellers of the transmitters, which in this embodiment are torque converters having guide wheels secured to a housing 6, transmit torque to the runners mounted on the shaft 5 which is supported in bearings in the housing and has flanges 7, 8 for connecting to a load on one or both sides of the housing. In another embodiment having three torque converters V, VI, VII, Fig. 3, the runner of converter V is directly connected to the secondary shaft 29 and the runner of converter VI is connected by a sleeve 30 to the first stage of a two-stage runners 31, 32 in the converter VII, the second stage of which is directly connected to the secondary shaft 29. Alternatively, the second stage of the runner may be connected by a second sleeve to the runner of a turbo coupling, the runner being secured to the secondary shaft. A filling pump 74, Fig. 7, in a reservoir 85 may be driven by gearing 75 ... 78 from the primary shaft 73, the gearing, together with the gearing 71, 72 from the input shaft 70, being located in bearings in a supporting member 79. Because the load caused by the gearing is taken by bearings in the member 79, the housing 84 and casing 86 of the reservoir may be of relatively light construction. The members controlling the filling of the transmitters may also be disposed between the transmitters. Each transmitter may be disposed within a cylindrical casing 108, 109, 110, Fig. 8, provided with flanges 90 . . . 95 whereby the parts are easily interchangeable. Flanges 90 and 95 may be secured to bearing housings 100, 101 adapted to be connected to following gearing 111, 112. The turbo converter providing the lowest speed range may have a two-stage runner and a two-stage guide wheel. Two arrangements, which are stated to be known, are described in which the impellers are connected to a driving shaft and the runners are connected by gearing to a countershaft serving as the secondary shaft.

Patent GB-1108584-A (GB)
Title: Process for the purification of phenols
IPC: C07C37/86
Filed: 1965-07-27
Abstract: A phenol, obtained by the partial oxidation of a secondary alkyl aromatic hydrocarbon followed by acid-catalysed cleavage of the hydroperoxide formed, is freed at least partially from carbonyl compounds which are present as impurity by neutralizing the cleavage reaction mixture, separating from the neutralized mixture a fraction containing the phenol and carbonyl impurities, heating this fraction with water or steam in contact with a strongly acid cation exchange resin containing free phosphoric, phosphonic, sulphuric or sulphonic acid groups, thus converting the carbonyl compounds to compounds having lower boiling points and separating these compounds from the phenol.  The process is particularly applicable to the purification of phenol itself but may also be used for the purification of other phenols, e.g. those obtained by the acid-catalysed cleavage of the hydroperoxides of o-isopropyltoluene, m-isopropyltoluene, p-isopropyltoluene, p-diisopropylbenzene, sec.-butylbenzene and b -isopropylnaphthalene.

Title: Process for producing diphenylamine
IPC: C07C209/64
Filed: 1959-09-22
Abstract: Diphenylamine is prepared by contacting aniline vapour with an alumina catalyst at a temperature from above 400 DEG  to 550 DEG C., condensing the effluent vapour and separating diphenylamine from the unreacted aniline and by-product ammonia, wherein the catalyst comprises activated alumina which has previously been impregnated with an aqueous solution of a water-soluble fluoride-ionproviding material, separated from the aqueous solution and dried.  The unreacted aniline is preferably recycled. The fluorideion-providing materials are defined as the water-soluble fluorides, such as hydrogen fluoride and the alkali metal and ammonium fluorides. Examples describe the process and compare the yields obtained with those from untreated alumina. Specification 473,739 is referred to.ALSO:Activated alumina which has been impregnated with an aqueous solution of a water-soluble fluoride-ion-providing material, separated from the aqueous solution and dried is used as a catalyst in the preparation of diphenylamine from aniline (see Group IV(b)). The fluoride-ion-providing materials are defined as water-soluble fluorides, such as hydrogen fluoride and the alkali metal and ammonium fluorides.  In an example a spraydried alumina gel which has been balled and calcined is stirred into a 2% aqueous ammonium fluoride solution.  After standing for 1 hour the solution is decanted and the alumina dried without washing. The alumina treated in this way is said to contain less than 1% of fluoride ion.

Title: Improvements in transmitting and receiving graphic records by wireless signals
IPC: H04N1/23
Filed: 1922-11-24
Abstract: 209,563. Etablissements E. BÚlin, and BÚlin, E. Nov. 24, 1922. Copying telegraphs.-In the wireless transmission of graphic records, the records are formed in relief or intaglio of constant depth on a rotatable drum, the surface is explored, as the drum rotates, by a stylus, the movement of the stylus actuates a relay, and the relay controls the generation of the high-frequency oscillations of the wireless transmission. The stylus is in the form of a point 1, Fig. 1, mounted on a spring tongue 2 carrying a contact 4 co-operating with a contact 5 to make and break a circuit between terminals 3, 9. The contact 5 is adjustable by a screw 7. This circuit-breaker is arranged in shunt with a relay controlling the circuit of a wireless transmission relay. The frame 8 carrying the circuit-breaker is moved axially of the drum A bearing the record as the drum rotates, to enable the point 1 to explore the surface helically. At the receiving station a drum B, Fig. 3, rotated synchronously with the drum A, carries a sensitized surface, and as it rotates moves axially in relation to an exposure opening M<1> through which light is reflected by a galvanometer mirror M controlled by currents derived from the wireless receiver whenever the point 1 moves over a portion in relief on the drum A. Light from a luminous point S, Fig. 4, passes through a condenser L, a diaphragm D, and a lens L<1> to the mirror M, and the reflected rays pass through a diaphragm D" and an aplanatic lens L" to the opening M'. Synchronous movements and synchronism indicators.-The rotations of the drum A and B are controlled by synchronized clocks at the transmitting and receiving stations as described in Specification 20908/14. The clock 1', Fig. 3, at the receiving station, closes at each beat a circuit from a battery 2<1> to an electromagnet 4<1> which thereupon attracts a lever 5<1> to release a pin 6<1> on a wheel 12 driven from the motor which drives the drum B. At each rotation of the wheel 12, a contact carried by the wheel completes a circuit from a battery 2" through an electromagnet 4" which thereupon attracts a lever 5" to release a pin 6" to allow the motor to drive the drum B through a friction clutch 8<11>. To ensure correct phase, the operator listens in a telephone to the transmitting station and operates a worm 11 to adjust the position of the contact on the wheel 12. Specification 19966/13 also is referred to.
