Patent GB-690416-A (GB)
Title: Improvements in or relating to the evaporation of liquids
IPC: B01D3/08
Filed: 1947-12-24
Abstract: <PICT:0690416/III/1> <PICT:0690416/III/2> In the evaporation of liquids in a cylindrical chamber having heated end-walls, a rapid rotational movement is imparted to the liquid about an axis which is normal to the heated surfaces so that the liquid is forced over and renews itself upon the heated surfaces by centrifugal action, while the vapours driven off from the liquid are collected in a free space at the centre of the body of liquid.  The evaporation of viscous liquids such as sugar juices and "black liquor" is referred to.  The evaporator shown is built up from three hollow annular parts 4 spaced apart by cylindrical walls to provide two chambers 3 and 3a. Co-axial paddle wheels 1 and 1a, each provided with four paddles 2, are disposed in the two chambers so that there is little axial and radial clearance between the paddles and the boundaries of the chambers.  The ends of the apparatus are closed by two cap-members, each of which has a vapour-outlet 12.  The inner peripheries of the hollow parts 4 are spaced from the axle of the wheels so as to leave free spaces 5, which permit communication between the two chambers themselves, and between each chamber and its adjacnt cap-member.  A heating fluid is circulated through the hollow parts 4, and the paddles are set in rapid rotation.  The liquid-to-be-concentrated is introduced through inlet 6.  It flows from the left-hand cap-member into chamber 3, wherein it is moved outwards over the heated walls by the centrifugal action of the paddles.  Some of the liquid evaporates in chamber 3; and the partially concentrated liquid which reaches the periphery of chamber 3 flows (by pressure difference) into chamber 3a by way of pipe 7 which opens into the periphery of chamber 3 at inlet 8, passes through the central hollow part 4, and discharges into the central free space 5.  The liquid is moved outwards over the heated walls of chamber 3a whereby further evaporation is effected; and the highly-concentrated liquid is discharged from the apparatus via pipe 7a, right-hand free-space 5, and outlet 11. The apparatus may be disposed vertically instead of horizontally, and more than two chambers can be incorporated therein.

Filed: 1954-11-29
Abstract: The invention comprises dyestuffs, which in the form of their free acids, are of formula <FORM:0785120/IV (b)/1> where A may contain substituents other than hydroxy and amino groups, X is H or a substituent other than halogen and R is H or an alkyl group.  They are made either by diazotizing an appropriate 2-sulphoaminobenzene and coupling with the required azo component or by condensing, preferably in an aqueous medium, equimolar quantities of cyanuric chloride and the necessary benzene-azo-naphthalene dyestuff.  The heterocyclic component may be made in situ and all reactions are preferably effected at below 5 DEG  C. to avoid side reactions and, also for this reason, the dyestuffs are preferably isolated at pH 6.4-7.8 and dried at 20-40 DEG  C. in the presence of buffering agents which maintain a pH of about 6.5, e.g. mixtures of disodium hydrogen phosphate with potassium or sodium dihydrogen phosphate. Specified diazo components are aniline-2-mono- and -2,5-di-sulphonic acids, 3-aminobenzotrifluoride-4-, 2,4 - dimethylaniline - 6-, 4 - chloro - 5 - methyl-, 5 - chloro - 4 - methyl-, 4 - acetylamino-, 4-chloro-, 4-methyl- and 4- and 5-methoxyaniline - 2- and 3 - acetylamino-, 3,4 - dichloro-, 3 - methyl- and 2,4 - dimethoxy - aniline - 6 - sulphonic acids.  The dyestuffs, as their alkali metal salts, yield orange colours on cellulosic textile material, e.g. when they are impregnated with a solution of the dyestuff and after-treated with an acid-binding agent such as caustic soda in an aqueous medium containing an electrolyte such as sodium chloride or sulphate or when printed with a paste containing the dyestuff and a substance such as sodium bicarbonate, which on subsequent heating or steaming, liberates an acid-binding agent. Examples are provided illustrating the preparation of the dyestuffs and their use in dyeing cotton, the diazo components being chosen from those listed above and the coupling components used are derived from 2-amino-, -methyl- and -n-butyl - amino - 5 - naphthol - 7 - sulphonic acids.  Specification 209,723, [Class 2 (iv)], is referred to.

Abstract: 1,160,426. Transistor sawtooth circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 3 Aug., 1966 [28 Aug., 1965], No. 34721/66. Heading H3T. In an electron-beam deflection circuit, the deflection coil Sp is connected in series with a resonant circuit T across the output of a linear amplifier AV, so as to reduce the voltage across the output of amplifier AV during the flyback period. Fig. 1 shows a line deflection generator for a radar display unit of the television raster type. A sawtooth generator SG, controlled by a pulse generator JG synchronized by line pulses at HS, has superimposed on it at TK, sinusoidal tangent correction signals before being fed to a linear amplifier AV feeding deflection coils Sp. The sweep is linearized by feed-back of a voltage developed across winding W3 due to capacitor C1 charging and discharging parabolically during each sweep. Transistor Tr2 is turned on during each flyback period so that diodes D1, D2 and capacitor C2 behave in a manner similar to that of a conventional booster diode circuit. Alphanumeric characters may be displayed (e.g. between interlaced scans) by setting switches S1, S2 to their other positions and turning on transistor Tr 1 so as to eliminate the compensating circuit. The feed-back path is then blocked during the flyback by diode D3. In Fig. 3 (not shown), transformer T3 is replaced by a choke loaded by the components shown connected to winding W2.

Title: Improvements relating to methods of and apparatus for defibrillation
IPC: A61N1/39
Filed: 1958-10-30
Abstract: 864,362. Electro-medical apparatus. INDUSTRIAL & MEDICAL ELECTRONICS Ltd., and LIGHTWOOD, R. Oct. 30, 1959 [Oct. 30, 1958], No. 34758/58. Class 81 (2). Apparatus for producing a pulse for defibrillation comprises means for charging a condenser which is subsequently disconnected from the charging source and connected to the patient, through whom it is partially discharged to provide the pulse. Timing means is provided for limiting the duration of the pulse. When power is supplied to the transformer T1, the condenser C2 is charged through rectifier W3, but closure of a key S3 causes energization of a relay A/3, the contacts A1, A2 of which disconnect the condenser from the supply and connect it to the output terminals a1, a2. At the same time a further contact A3 connects the power supply through rectifier W2 to condensers C3 . . . C8, in series with relay B/1. The initial charging surge energizes the relay B/1 which subsequently releases when the condenser charging rate falls. Consequently contact B1 is at first closed, to connect the condenser C2 to the patient, and then opened, to terminate the pulse, after an interval determined by the setting of switch S6, by means of which the number of parallel-connected condensers C3 . . . C8 is selected. When the switch S3 is released, relay A/3 reconnects condenser C2 to the charging circuit and contact A3 discharges the pulse timing condensers through R7. The magnitude of the pulse administered is determined by the transformer tapping switch S2.
