Title: Process of resolving dl-serine m-xylene-4-sulfonate
Filed: 1969-10-06
Abstract: 1,218,158. Serine m - xylene - 4 - sulphonate. TANABE SEIYAKU CO. Ltd. 6 Oct., 1969 [4 Oct., 1968 (2)], No. 48959/69. Heading C2C. The invention comprises DL-, D- and L- serine m - xylene - 4 - sulphonate. The DL form is prepared by neutralizing DL-serine with mxylene-sulphonic acid in a suitable solvent. The enantiomers may be obtained by forming a supersaturated solution of DL-serine m-xylene- 4-sulphonate in a solvent, seeding or dissolving one of the optically active enantiomers thereof into the solution thus making it predominant over the other entiomer in the solution, allowing the predominant enantiomer to crystallize out and recovering the enantiomer. The mother liquor may be treated to produce the other enantiomer. The separated crystals may be purified by adding to a minimal amount of solvent which will dissolve the racemic modification in the crude crystals, stirring, and recovering the crystals. Optically active serine can be obtained from optically active serine mxylene - 4 - sulphonate without racemization by treating with an ion-exchange resin.

Abstract: 1518238 Cathode ray tubes RCA CORPORATION 24 Nov 1976 [28 Nov 1975] 49025/76 Heading H1D An addressable video line generator for a flat image display tube includes a cathode 14, e.g. a photocathode, or a cathode which emits electrons in response to ion impact, and an array 43, 45, 47 of planar electron multipliers extending therefrom, each of which is provided with a plurality of dynodes 20a ... i, the grouping of the connections to the various dynodes and multipliers being arranged (Table 2, not shown) to minimize the number of beads passing through the device envelope while permitting random addressing of the lines; coded printed circuit wiring (16, Fig. 2, not shown) on the cathode support 12 ensures the desired manner of connection of the various dynodes when the dynode supports 18 are assembled on the cathode. In the arrangement shown, for a display tube usable with a 512 scan line television system, each multiplier has 9 dynodes, all of which are addressable, and an inhibiting voltage applied to any one of which switches off its multiplier, the dynode connections being made to successive half groups of previous groups (Table 2), such that 18 leads suffice to permit random addressing of the lines. The arrangement may be employed in a colour television tube (Fig. 7, not shown), in which the sheet beam produced by any multiplier is thereafter modulated by an array of modulating electrode pairs orthogonal to the beam, to control the incidence of the latter on colour phosphor stripes (68) also orthogonal to the beam.

The electromagnets 13, 14 are operated by switches 16, 17 which lie in the path of a cam 23 rigidly attached to the ring rail so that the motion of the piston 6 and therefore the ring rail 2 is reversed at each actuation of the switches 16, 17. So that shaped packages may be built the switches 16,17 are vertically moved during winding cams 18,19, driven by motors M 2 , M 3 , the shape of the package depending on the shape of the cams and the speeds of the motors. At the start and finish of winding, rapid motion of the ring rail is obtained by opening the by-pass valve 32 in the reflux duct 31, in addition, the rail may be brought to a halt by closing a valve 26 in the duct 10. By suitable arrangement of switches and time delay mechanisms the valves 26, 32 may be automatically operated so that waste yarn is wound on to the bottom of the spindle at 38 before the winding begins. In addition transfer tails 36, 37 may be wound at either or both ends of the package before or after the main winding. Three separate programmes of winding are described together with the necessary electrical components and circuits.

A dispensing device for mounting in the neck 2 of a container 1 comprises two passages 9, 10 separated by a partition 8, the passage 10 being closed by a wall 7 and communicating with the interior of the container via at least two apertures 15, 16 so that the portion of the passage between the wall 7 and aperture 16 defines a measuring chamber 12 while the portion of the passage between the aperture 16 and the end 8a of the partition defines a chamber 13 for excess liquid. The device, which may be of plastics material, is provided with a flange 19 for sealing engagement with the neck of the container and shaped so as to form a passage 20 for the flow of liquid into the measuring chamber. In operation, upon tilting the container liquid flows via the passage 20 and aperture 15 to gradually fill the measuring chamber, air entering the container via the aperture 16. When the aperture 16 is closed by the rising liquid, excess liquid enters the chamber 13 until the pressure in the chamber equals atmospheric pressure. The container is then returned to the position shown so that the excess liquid is sucked back into the container and the measured quantity flows into a chamber 11 in the device. Upon inverting the container again, the measured quantity is dispersed through the passage 9. An air vent 21 is provided in the device.
