Title: Improvements in treating yarns
IPC: D01C1/02
Filed: 1932-01-11
Abstract: 399,800. Treating yarns. HART, O. TUDOR-, 52,-Maida Vale, London. Jan. 11, 1932, No. 748. [Class 120 (iii).] Coir yarn, the fibres of which have been boiled in alkali, is subjected to a rubbing process either before or after weaving, in order to impart flexibility, glossiness and greater affinity for dyes. The alkali treatment may be effected before or after spinning. The yarn may be woven without lubrication, and carpets made therefrom can be made to resemble hair carpets ; it may be used for tying purposes, for example in horticulture where resistance to mould, blight, vermin, and damp is required. The woven material may be printed like linen or cotton. In an example, coir yarn is tied up in hanks, soaked in hot water or wash liquor, and boiled for 2-3 hours under pressure in a solution containing 1“ per cent caustic soda. The yarn is washed in boiling and in cold water, and boiled in a solution containing 1“ per cent alkali, comprising equal parts soda ash and sodium carbonate, with 0.1-0.2 per cent sulphonated soap, and then washed. The yarn may be bleached and treated with acid, and is lustered on a yarn-lustering machine, or after weaving, by rubbing with brushes or bristles of coir, or by passing the yarn over pulleys having V-shaped peripheries faced with coir yarn, and by rubbing with pads faced with coir yarn intermediate the pulleys. The pulleys may move reversely to the direction of travel of the yarn. The yarn may be beaten in a beetling-machine or calendered before or after weaving and may be dyed at any stage after the alkali treatment. Specification 328,638, [Class 120 (iii), Yarns &c.], is referred to.

Title: Apparatus for measuring quantities of liquid
IPC: G01F3/38
Filed: 1927-01-10
Abstract: 264,188. Flindt, P. A. Jan. 10, 1927. Vacuum apparatus. - A liquid meter, which may be controlled by coin-freed apparatus and may form part of a vacuum-feed system, comprises a measuring chamber 1, Figs. 1 and 2, having inlet and outlet valves 6, 7 operated by springs 8, 9, a float 2, and a continuously rotating arm 29. In the position' shown, an arm 14 on a shaft 10 is locked bv engagement with a pivoted member 15, and a stop 11 on the shaft engages a bell crank lever 13, 24 to hold the valve open. When the float 2 reaches its lowest position, it acts on a stop on a rod 3 and thereby depresses the member 15 to free the arm 14; the spring 9 thereupon closes the valve 7, and the lever arm 24 acts through the stop 11 and shaft 10 to turn the arm 14 into its vertical position. During this motion, a sleeve 26 is turned by contact of a tappet with a stop 27, so that a wing 28 is moved into the path of the end of the arm 29, which then moves the arm 14 into the position 30, where it is locked by engagement with the pivoted member 16, in order to hold the valve 6 open. When the float 2 reaches its highest position, it acts through a stop 4 to raise the member 16, and the arm 14 is returned to its initial position, the arm 29 acting for this movement on a wing 37. Registering mechanism is operated by a part 31 of the wing 28 or 37 acting on a ratchet wheel 32, by a separate moving arm, or by the float. When the vessel 1 is to be used as a vacuum tank, a suction connection 60, Fig. 5, and an air hole 67 are controlled by a valve plate 62 with an aperture 63, the plate being carried by a pivoted arm 66, acting on by a spring 64 and extending into the path of the arm 14. If desired, the plate 62 may be replaced by a cock operated by the arm 14. When it is required to govern the meter by coin action, the stop 27 is replaced by an adjustable stop actuated by a coin, or is constituted by that part of a coin exposed by a slot 71, Fig. 7, in a coin chute 70. The coins are discharged singly by means of a segmental cup, open at its edges 75, which is rotated directly or through gearing from the shaft of the ratchet wheel 32. The coin chute 70 is normally parallel to the path of the arm 14, which is offset at 76 to clear the shaft of the cup ; it may, however, be set obliquely and be adjustable for use with various sizes of coins.
