    • 24,066. Young, G. C. G., Young, J., and Waddell, M. M. Nov. 22. Processes; spindle apparatus; drawing - frames; roving-frames; slivenrubbing apparatus; spinning-machines with twisting arrangements at delivery. -The process of spinning flax and other yarn described in Specification No. 4394, A.D. 1905, is carried out by first drawing out the rove either in a wet or dry condition and winding it into a roll without twist, then transferring it to a revolving delivery spindle, whereby it is twisted as it is drawn off to be wound into a roll. In the Wet-spinning of flax, the rove is led through a trough C, Fig. 1, drawn by rollers B, dried by passing with a travelling absorbent blanket D round a drying - cylinder D', and finally wound into a roll A by a drum E. Supporting-rollers b, d are provided for the blanket and a longitudinally reciprocated roller b above the rollers b serves to condense the rove and prevent it from lapping on the roller B. Other arrangements are shown, in one the blanket being dispensed with, and in another, two drying-cylinders being employed. When it is not desired to wet the rove, it passes from the drawing - rollers between condensing-rubbers to the roll. The roll A' of untwisted rove is transferred to a spindle F, Fig. 6, which is rotated rapidly to twist the rove as it is drawn off by rollers G, and the fully twisted rove is wound on a roll A by a drum El. A shield H, which may be stationary or driven at any desired speed, surrounds the spindle to prevent excessive ballooning and control the drag. In some cases, the spindle is inverted and the yarn drawn off, through a water trough.

    • 28,077. Cross, C. F., and Young, J. Dec. 19. Cyanides ; oxalates ; sulphocyanides.-Consists in heating a mixture containing a nitrate, preferably an alkali nitrate or a mixture of nitrates, an organic compound such as an aldehydic or ketonic compound preferably a carbohydrate of the sugar type, an alkali such as barium hydroxide or caustic soda or a mixture of alkalies, and enough water to secure an intimate mixture of the constituents, to a temperature of from 150‹-170‹ C., whereby, when caustic soda is used, sodium oxalate and cyanide are formed. The mass is extracted with water, and, on evaporating, the oxalate crystallizes out along with sodium carbonate, which is also formed, leaving the cyanide to be obtained from the mother liquor in any of the usual ways. If metallic iron is added to the mixture, a ferrocyanide results, while, by adding sulphur or a sulphur compound, a sulphocyanide is the chief form in which cyanogen is obtained. The Provisional Specification states that the nitrate may be mixed with an alkali or alkaline earth or a mixture of both, while the organic matter may advantageously be waste material, such as the matter contained in the liquid.obtained by boiling esparto grass preparatory to making it into paper, or waste products from distilleries or from starch manufacture, which contain carbohydrates.
