Abstract: 514,865. Rectifying alternating current; reactors. BRITISH THOMSON-HOUSTON CO., Ltd., WHITELEY, A. L., and LUDBROOK, L. C. June 9, 1938, No. 17191. [Class 38 (ii)] An arrangement for producing a D.C. voltage of adjustable magnitude for use, e.g., as a control voltage for " Thyratrons " or for operating relays comprises a pair of reactor windings 3 on on the outer limbs of a saturable three-limbed core and connected through rectifiers 5 and load impedances 6 to an A.C. source 4 as shown. Thus by means of a D.C. saturating winding 2 on the centre limb of the core, a D.C. voltage which is a function of the saturating current is produced at A, B. In a modification, Fig. 2, the rectifiers are oppositely directed so that the points A, B are at equipotential in the absence of saturating current in the winding 2, while a voltage of variable magnitude and reversible polarity is obtainable by varying the magnitude and direction of the saturating current. In such an arrangement, the resistances 6 may be the operating coils of a pair of non-polarized relays used in a directional scheme, the two relays responding respectively to different directions of current in the saturating winding. The latter may be in two parts arranged on the outer limbs of the core, Fig. 4 (not shown). Specification 508,847 is referred to.

Title: Process for purifying titanium tetrahalides or zirconium tetrahalides
Inventor: WIGGINTON RAYMOND JAMES
IPC: C01G25/04
Filed: 1954-06-18
Abstract: Titanium and zirconium tetrahalides are purified at least from vanadium by passage through a fluidized bed of particles at least the surface of which are metallic.  Metals referred to are copper, zinc, iron, nickel, calcium, magnesium, aluminium, titanium, lead, antimony, tin, sodium and alloys containing at least one of these metals; sodium carbonate particles on which sodium has been deposited by rapid agitation in nitrogen at 160 DEG  C. are also referred to. Such metals as iron and chromium will generally also be removed.  The temperature of the purification should be such that decomposition of the halide to be purified does not take place; for the undiluted tetra bromides or chlorides of titanium and of zirconium temperatures under atmospheric pressure of 150-300 DEG  C. and of 300 DEG  to 400 DEG  C. respectively are suitable. The halides may, if desired, be diluted, e.g. with nitrogen, carbon monoxide and/or carbon dioxide, and may come directly from the halogenation with a halogen and carbon of titaniferous or zirconiferous material.  In the latter case it is desirable to remove solid matter such as ferric chloride, entrained in the gases; diluent gases, which may include chloride and silicon tetrahalide, may be separated by condensing out the metallic halides before or after purification in the fluidized bed.  The particles of the bed should be periodically or continuously replaced or regenerated; two or more beds may be operated e.g. when using three beds, at any given time, a first bed may be removing a major part of the impurities whilst a second is removing the remainder and a third is being regenerated, said third bed having been employed as the bed removing the major part of the impurities in the preceding run. Specification 674,315 and U.S.A.  Specifications 2,530,735, 2,416,191 and 2,396,458 are referred to.

IPC: D03C19/00
Filed: 1917-12-12
Abstract: 119,160. Drinkwater, J. H. Dec. 12, 1917. Cards; cards, punching.-In producing cards for dropper jacquards for Levers lace machines &c., two patterns are punched on the same cards simultaneously by transposing the pairs of numbers indicating the units of motion of the two patterns into single arbitrary numbers, which are those ordinarily used on the figure sheets of single patterns requiring a larger number of droppers but indicating for the same punching as is required by the pairs of numbers, and using these arbitrary numbers in the figure sheet from which the cards are punched. Thus, in the case of two patterns, each necessitating the use in the jacquards of three droppers for each thread guide-bar of one, two, and four spaces respectively, the arbitrary numbers used are those for a six-dropper card, the left half of the card B being used for one pattern and the right half for the other. The cards are run in opposite directions for the two patterns and the cards are arranged in two series for the two jacquard cylinders in the usual manner. The numerals immediately to the left and right of the card indicate the units of motion corresponding to the punchings in the respective halves of the card, while the numerals of the second column to the right of the card are the arbitrary numbers, indicating the units of motion corresponding to the punchings of the whole card for a half, one, two, four, eight, and sixteen dropper jacquard, and are used in the punching in the ordinary piano punching-machine. The numerals at the top of the card indicate the droppers set by blanks at the corresponding parts. The transposition of the numbers may be facilitated by the use of a number table or may be effected by a form of typewriter.
