Title: Improvements in or relating to electric emulsion treater
IPC: B01D17/06
Filed: 1956-07-17
Abstract: 833,749. Electrostatic separators. PETROLITE CORPORATION. July 17, 1956 [July 28, 1955], No. 22136/56. Class 117 An apparatus for electrostatically resolving emulsions, e.g. an oil-continuous petroleum distillate, comprises a container 9 having a zone 15 containing electrodes and communicating through an opening 77 with a zone 76 in which is an insulator 80 supporting a conducting member e.g. a rod 75, which passes through the opening 77 and is connected to the electrodes, a valve 90 on the rod 75 adapted to close the opening 77 on movement of the rod 75 to a predetermined position, and means, e.g. nut 102 on the rod 75, for moving the rod 75 between the predetermined position and another position in which the valve 90 opens the opening 77. The container 9 is similar in its arrangement of parts to that described in Specification 833,750 having a central dished partition and a set of intermeshing cylindrical electrodes in each chamber, emulsion being delivered to and taken from each chamber by perforated pipes at the bottom and top respectively of the chambers. The top set of electrodes is supported by three conducting rods 75 each adjustably secured by a nut 102 to a plate 101 bolted at 104 to the insulator 80 which has a flange 96 bolted at 97 to a flange 79 on the internal wall of a housing 76. On each rod 75 is an adjustable valve member 90 adapted to seat on a flange 91 surrounding an opening 77 leading to the interior of the container 9. Two of the housings 76 are closed by removable domes 111 but the other by a cover 84 closed by a flange 110 on a bushing 106 enclosing a conductor 107 connected at one end to a voltage source and at the other, at 109, forming a slip fit in a hood 103 bolted to the plate 107. The upper portion 81 of the housing 76 is filled with a dielectric liquid, e.g. transformer oil, and the emulsion to be treated may be allowed to rise through the opening 77 into the tower portion 82. A gas, e.g. air, nitrogen, helium, or carbon dioxide from a source 126 may be employed as a buffer in lines 115...120 and in the portion 82 to separate the oil and emulsion, a bellows 124 serving to equalize pressure in the portions 81, 82. If desired, the rod 75 may be fixed to the insulator 80 which is then vertically adjustable. The lower electrode set is suspended by a conductor 53 in a central tube 66 having a housing 176 similarly constructed to the housing 76, with an insulator 180 and valve 190. Dielectric liquid fills the upper portion 181 to a level 219, a pipe 220 being filled with a gas. Emulsion may rise up the tube 66 to contact the insulator 180.

Patent GB-703230-A (GB)
Title: Process for the separation of gases from gas mixtures by adsorption
IPC: B01D53/08
Filed: 1950-06-19
Abstract: In a process for separating gases from gaseous mixtures wherein a solid adsorbent is passed down a vertical column in countercurrent with the gas mixture through an adsorption zone, a fractionating zone, and a desorption zone, the desorption pressure of each substance adsorbed by the adsorbent is lowered by cooling the adsorbent when entering or in the fractionation zone to a value lower than the desorption pressure on charging the adsorbent to equilibrium in the adsorption zone.  The adsorption zone may also be cooled.  As described in Specification 703,162, the adsorbent may be undercharged in the adsorption zone, or the adsorption zone may be larger in cross-section than the other zones when the gas mixture contains only a small concentration of the gases to be separated.  Fractions containing ethane and ethylene in high concentration may be obtained by contacting a hydrocarbon mixture with active carbon.

Patent GB-614990-A (GB)
Title: A method of producing a derivative of the blood-sugar decreasing hormone, and the insulin derivative thereby produced
IPC: A61K38/00
Filed: 1946-07-29
Abstract: A derivative of the blood-sugar decreasing hormone is obtained by treating it with reagents, which similarly to isocyanates, will attack amino-groups in such a manner that a hydrogen atom, or hydrogen atoms in these groups are substituted, care being taken in the choice of the usual reaction conditions such as time, temperature and concentration of the components employed in the reaction, that the reaction proceeds only to a point at which the hormone maintains its entire, or an essential part, of its blood-sugar decreasing effect, but of altered character so that the effect in the diabetic organism is extended over a longer period of time.  Preferably, the reaction is carried out in a homogeneous system, e.g. acetone-water mixture.  The final point of the reaction is found by biological experiments to occur at 1-30 X 10-3 m Mol. titratable amino groups per m Mol. total-N in the blood-sugar decreasing hormone and may also be determined titrimetrically.  Examples illustrate the use of benzoyl chloride, the benzyl ester of chloroformic acid and acetic anhydride as reagents which attack amino groups whilst additional reagents specified are acyl chlorides, acyl anhydrides, ketenes, alkyl halogens, aldehydes and ketones and xanthydrol. Specification 604,327 is referred to.

[Also in Division G1] In an apparatus for producing colour combination and patterns in a manufactured article, a master composition is analysed by elemental areas to produce a binary coded punched tape which is subsequently employed to control the individual application of colour elements from storage devices to discrete areas of the manufactured article. Colour analyser and tape perforator, Fig. 3. A transparent colour picture 1 is wrapped around a scanning cylinder 17. The cylinder is rotated in tile-width steps by a motor 19, controlled by a switch 21 closed one per revolution of colour matching commutators 23, 25, 27, and a carriage 37 is axially advanced one tile-width for each revolution of the cylinder for a straight line mosaic. The carriage 37 supports a light 39, an optical system 43, 45, 47 for directing light through the picture 1 and dichroic mirrors 49, 51 and photo-cells 53, 55, 57 which are responsive to the red, green and blue components of the colour of the elemental area being scanned. The photo-cells are connected into bridges 71, 73, 75 fed from an oscillator 67. The bridges and adjusted by commutators 23, 25, 27 whereby 40 primary colour combinations are selectable. The commutators are driven by a motor 89 in step with a member 87 of a perforating device 83 bearing forty angularly spaced rows of punches, providing from zero to six holes, in distinctive combinations. When during a rotation of the commutators a combination is reached for which the three bridges are in balance an electromagnet 77 is energized to cause the punches to perforate a tape 90. The picture 1 is sequentially scanned in elemental areas to produce a tape bearing perforations of the colour pattern of the picture which is subsequently reproduced by a tile setting machine. Tile setter. Fig. 6. The prepared tape is fed through a photo-electric tape reader 107 the outputs of which are amplified by an amplifier 117 and fed to a matrix 119. The matrix is selectively responsive to pulses of the six-character code develop one of forty distinctive signals which is applied to one of the forty tile selector gates 121 provided around a tile setting device 141. A tile released by a gate slides down a coned drum of the device 141 to the next position on a tile pattern 153 being set up on a rotating drum 149. When in position the tile interrupts a light beam to a photocell, not shown, which causes a tile-setting plunger 147 to be depressed by a solenoid thereby fixing the tile into position.
