Abstract: 166,265. Coker, W. G. May 27, 1920. No Patent granted (Sealing fee not paid). Stringed instruments, tuning-pins for.-Relates to tuning-pegs for banjoes, guitars, mandolins, violins, &c., of the kind in which a flange D, Fig. 2, bears against one surface of the head C and a squared &c. stem A carries a finger-piece E which can slide but not turn thereon under pressure from a nut G screwing on the end of the stem to press the finger-piece against the other surface of the head; and consists in providing a conical surface B on the stem A to engage a corresponding conical surface in the head C. A metal washer N with conical hole and a tapered sleeve O may be provided, which may turn relatively to the head C and to the cone B to reduce wear on the wood, and may also be made in one piece. The conical surface B may coact with a conical surface in a split sleeve secured to the head by a flange and screws, and for " octave pegs " on banjoes the string may be wound on a groove in the finger-piece instead of in the slotted extension M. In the form shown in Fig. 3, where the peg extends through two wooden walls C', C', the walls are supported by a flanged sleeve P mounted on the stem A, the sleeve having a hole Q and the stem a notch R through which the string can be passed.

Title: Improvements in or relating to the manufacture of titanium
Inventor: GRAY JAMES JOHN
IPC: C22B34/12
Filed: 1955-08-22
Abstract: In the extraction of titanium by reducing its halide with an alkali or alkaline earth metal, the subsequent leaching of the products is improved by application of ultrasonic vibration to the leaching medium.  Leaching may be in water, aqueous solution of a mineral acid, or liquid ammonia; the vibration may be applied during primary leaching or whilst the Ti powder obtained therefrom is washed with water.  Preferably a fluidizer is employed having a polythene cone and in which fluidization is produced by feeding water into the bottom of the cone; the vibration being produced either by a barium titanate disc at the top of the moving bed in the cone and radiating downwardly (1 megacycle 400 watts), or by a magneostriction element inserted in the moving bed (26 kilocycles, 500 watts).  Specification 697,917 is referred to.
