Title: An improved process for stabilising and purifying cellulose triacetate
IPC: C08B3/22
Filed: 1938-11-08
Abstract: 511,822. Cellulose esters. NORTH AMERICAN RAYON CORPORATION. Nov. 8, 1938, No. 32427. Convention date, Nov. 22, .1937. [Class 2 (ii)] Cellulose triacetate is. purified and stabilized by introducing it in the solid state into anhydrous liquid ammonia for the purposes of removing cellulose diacetate by dissolution and of removing acid catalyst by neutralization, and subsequently separating the ammonia from the cellulose triacetate. The process may be carried out in presence of an organic or inorganic auxiliary agent which is a non-solvent for the.triacetate and is inert towards ammonia. Since ammonium sulphate is only slightly soluble in anhydrous liquid ammonia it is preferable to cover the crude cellulose triacetate with a sufficiently large excess of liquid ammonia to dissolve the sulphate. The temperature of treatment is preferably about -33‹ C. but it may be lower or higher than this value. Benzene, ethers, esters, alcohols, nitrates, sulphites, or ammonium salts, may be used as auxiliary agents with the liquid ammonia. The crude triacetate may be prepared with sulphuric acid, hydrochloric acid, a sulphonamide, a phosphoric acid or an acid salt, or other catalyst which can be neutralized by liquid anhydrous ammonia with formation of a harmless salt. U.S.A. Specifications 1,173,336, 1,544,809, 1,954,729, 1,966,756, - 2,012,382, 2,019,921, 2,066,584, 2,071,333, 2,072,253, 2,072,260, 2,072,270, 2,073,052, 2,095,334 and 2,095,822 are referred to.

Title: Improvements in and relating to measuring apparatus
IPC: G01B11/04
Filed: 1958-10-13
Abstract: 861,029. Measuring dimensions. GRUNDIG, M. Oct. 13, 1958 [March 12, 1958], No. 32572/58. Class 40 (3). The distance between two points on an object which are optically distinguishable from the remainder of the object is determined by producing electric signals each having a value relative to a datum representing the position of one of the points relative to a datum, and comparing the two signals to deduce the relative position of the points and hence the distance between them. In Fig. 1, the edges 1 and 2 of material in band form are illuminated by light sources 4, 5 and the images projected via rotating mirrors 6, 7 on to photomultipliers 10, 11. As the image of the edge of the illuminated band passes through the slotted or perforated stops 12, 13, the photo-cells emit short pulses which are passed to a cathode-ray tube 19 where they appear as deflections of the trace in opposite directions. The mirrors are driven synchronously by motors fed from a common source and each provides a synchronizing pulse (e.g. by a coil and rotating magnet) to establish a datum time for each measuring pulse. These synchronizing pulses represent the position from which deviations of the edge of the material are to be measured, and the pulses are fed to a triggered time-base generator 18 to derive the scanning voltage for the tube. The measuring pulses are fed to the tube in alternate scans (e.g. by staggering the mirrors as shown) so that if the edges of the material are equidistant from the central datum point the pulses will appear one above the other. Movement of one edge relative to the other (i.e. change of width) will cause the pulses to appear staggered (as shown) while lateral displacement of the whole material shifts both pulses equally. Calibration marks can be generated as blacked-out or brightened points along the trace. In an alternative arrangement (Fig. 2, not shown) the synchronizing pulses are passed to flip-flops which are returned to their stable states by the measuring pulses. The outputs of the flip-flops are square pulses of length proportional to the distances to be measured, and are converted into voltages for indicating, controlling or recording purposes.
