Title: A Device for Forming and Presenting to Dummy Shuttles of a Loom Coils of Weft Yarn.
IPC: D03D47/26
Filed: 1968-06-07
Abstract: 1,173,710. Shuttleless looms. RUTI MACHINERY WORKS Ltd. 7 June, 1968 [7 June, 1967], No. 27332/68. Heading D1E. Particularly for a travelling wave shedding loom, coils of weft which have been wound on a flat blade 21 by a rotating element 34 are pushed along the blade by a pin 50 which extends through a slot in the blade and are located between releasable retaining means until they are taken by a dummy shuttle 18. As the coils are rushed along the blade by pin 50 another pin 52 acts in a perpendicular direction to move a spring 40 carrying a stop 44 to allow the coils to pass. The stop 44 prevents coils from moving back along the blade on return movement of pin 50. A second stop 43 on a spring 39 prevents the next coil from being unwound as a previous coil is picked. When the shuttle takes a coil it displaces the stops 43, 44 to facilitate removal of the coil and then as the shuttle is moved the stop 43 re-engages to prevent more than the desired amount of yarn from being taken. A blade 32 prevents the blade 21 from rotating in its bearings 31. Reference has been directed by the Comptroller to Specification 1,029,373.

Title: Improvements in or relating to producing sodium cyanide
IPC: C01C3/10
Filed: 1963-07-11
Abstract: A process of preparing sodium cyanide dihydrate crystals comprises preparing an aqueous solution containing less than 820 g./l. NaCN by substantially neutralizing with hydrogen cyanide an unsaturated sodium cyanide solution, to which sodium hydroxide has been added, cooling the resultant solution to saturate and then supersaturate it within the zone defined by its saturation and supersaturation curves, and adding NaCN.2H2O seed crystals to the supersaturated solution in order to form larger crystals of NaCN.2H2O.  The NaOH content of the unsaturated sodium cyanide solution may be between 30 and 100 g./l. An excess of 0.2 to 3.0% by wt. NaOH may be present after neutralization with hydrogen cyanide, which may be added in the liquid form.  The solution to be neutralized by hydrogen cyanide may be formed by adding mother liquors of the crystallization step to a sodium hydroxide solution having a concentration corresponding to NaOH.H2O.  In an example, NaCN mother liquors from a crystallizer-decanter are mixed with a hot aqueous NaOH solution corresponding to NaOH.H2O, cooled, injected through a Venturi tube wherein it is mixed with liquid HCN which is added at a rate regulated by the sodium hydroxide flow.  The resultant solution is pumped to a heat exchanger wherein it is cooled to the desired supersaturation state. The supersaturated solution is introduced into the lower part of the crystallizer-decanter together with NaCN.2H2O seed crystals.  Large crystals are extracted from the bottom of the decenter. Specification 230,423 is referred to.
