Title: Improvements in the purification of acrylic esters
IPC: C07C69/54
Filed: 1959-05-01
Abstract: Alkyl esters of acrylic acids are separated from their mixtures with one or more alcohols which are completely soluble in water by contacting the mixture with water or an aqueous solution of a salt and with a liquid hydrocarbon which is completely miscible with the ester to be separated, essentially insoluble in water and has a lower affinity than water for the alcohol from which the ester is to be separated to form an organic phase containing the ester and an aqueous phase containing the alcohol, and separating the phases.  The alcohol and ester can be recovered from their respective phases by distillation.  The hydrocarbon preferably has a boiling point above that of the ester.  Aliphatic saturated hydrocarbons are preferred but unsaturated and also aromatic hydrocarbons are also specified. Salt concentrations within the range of about 3 to 25% by weight in the aqueous phase are mentioned.  It is preferred to maintain the aqueous phase as the continuous phase.  The process may be operated continuously.

Abstract: 220,744. Sterling Telephone & Electric Co., Ltd., and Holbeach, W. M. June 6, 1923. Wireless tuning-apparatus, adjustment devices for.-A coarse and fine adjustment for electrical apparatus, such as variometers, used for wireless purposes, is obtained by mounting the shaft 4 to be adjusted in a bearing 6 secured to, or forming part of, a stiffly-moving rotatable bracket 7, in which is mounted a, handle 10 connected to the shaft 4 through gearing, such as a worm 11 and worm-wheel 13. Coarse adjustment is effected by turning the handle about the axis of the shaft 4, when the bracket and bearing turn stiffly in the plate 8 and carry the shaft 4 with them. Fine adjustment is effected by rotating the handle about its own axis, the bracket and bearing remaining stationary. The surface of the blocks 1 - - 3 carrying the plugs and sockets to receive the coils are placed at an angle to the axis of the shaft 4 to provide clearance for the handle, and to prevent undesired capacity effects from the hand' of the operator.

Abstract: 1307075 Digital to analogue conversion SANDERS ASSOCIATES Inc 26 March 1970 [27 March 1969] 14946/70 Heading G4H A system for translating the position of a point image on a cathode-ray tube, rotating it, and translating the rotated image, employs a multiplying digital to analogue converter. An analogue input representative of a position of the display is fed into the D to A converter at 41, Fig. 5, digital values of cos #, where # is the angle through which the image is to be rotated, are used to control switches 42 and 44. The sign bit controls switch 42 and the remaining bits control switches 44 which feed the analogue input through weighted resistors 45. In the full system as shown in Fig. 4 the value of the X co-ordinate is supplied on line 21 where it is added by unit 23 to the value of the X translation before rotation. This value of the X co-ordinate is then fed to multiplying digital to analogue converters of the type described so that outputs in the form X1 cos # and X1 sine # are obtained. Values of Y1 sine # and Y1 cos # are obtained in a similar manner. These values are then fed to adders 51, 52, 53 and 54 which in turn feed amplifiers 48 and 49. Values of X1 cos # X1 sine # Y1 sine # and Y1 cos # are combined together with the values of the translation of the co-ordinates following the rotation in such a manner that the appropriate value of the X and Y co-ordinates following rotation and translation are produced. This value of the X and Y co-ordinates is compared in comparator 63 to ensure that the image has not been moved off the cathode-ray tube.

Axle-trucks and bogies; springs, arrangement of; axle-bearing guiding arrangements. - In a susp e n ion for railway vehicles, spring constrained means 12, Fig. 1, permits limited depression of a wheel beyond the normal equilibrium position under load, e.g. on passing over a sagging rail joint, to an extent limited by the spring constrained means becoming a rigid abutment. The spring 10, Fig. 2, is attached to the vehicle axle and is connected to a thrust block 20 by a bolt 21 which passes through a bracket 24 attached to the bogie frame, a counter spring 25 being situated between a flange 26 on the block 20 and the bracket 24. When the vehicle wheel passes over a depression in the track the axle drops and the springs or discs 25 are compressed until the thrust block 20 contacts with the bracket 24 whereupon further downward movement of the wheel is arrested. A spiral spring may be used instead of the laminated spring. In Fig. 1 a laminated spring 10 is pivoted at 19 to a bracket 11 on the bogie frame and the ends of the spring are connected by rods 9 to an equalizing bar 8 which is pivoted at 7 to a stirrup 4 supported by the axle-box 2 by a yoke 3 and friction rings 17, 18.
