Title: Pre-bending device for thick strip
Inventor: O'BRIEN JEREMIAH WAGNER
IPC: B21C47/06
Filed: 1964-10-27
Abstract: 1,119,932. Winding and reeling. UNITED ENGINEERING & FOUNDRY CO. 6 Oct., 1965 [27 Oct., 1964], No. 43852/64. Heading B3E. Apparatus for bending the leading end of strip to be coiled on a reel comprises a pair of rolls engaging one surface of the strip and rotated to have a peripheral speed equal to that of the strip and a third roll adapted to engage the other surface of the strip to lie in nested relation with the first two rolls, said third roll being carried by a member so as to be movable from a strip engaging position and being rotated at a peripheral speed greater than the speed of the strip so that once the leading end of the strip is fed between the rolls and a bending pressure is established to bend the leading end, the member and third roll will be automatically displaced out of the nested relationship. Strip S from a rolling mill is passed between rollers 19, 21, carried by an adjustably pivoted frame 26 and driven at the speed of the strip, and a roller 22, carried by an arm 35 pivoted at 36 and driven faster than the strip, to a reel on which it is wound with the aid of a belt wrapper. The roller 22 may be of a diameter larger than that of the rollers 19, 21 and driven at the same angular speed. As the strip end passes between the rollers the high speed of the roller 22 causes the arm 35 to pivot to carry the roller 22 away from the rollers 19, 21 in the direction from which the strip is fed. In a modification, Fig. 3 (not shown), the arm carrying the fast roller is moved in the direction of its length, against spring pressure, by the passage of the strips between the rollers so that the lower end of the arm engages a driven roller which assists the pivoting movement of the arm swinging the roller out of its bending position.

Abstract: 1,059,587. Roller mills. TORRANCE & SONS Ltd. Nov. 12, 1963, No. 44719/63. Heading B2A. The R.P.M. ratio between the feed roll 1 of a roller mill and its next adjacent roll 2, and the overall speed of the rolls are variable within predetermined limits. As described, the roll 2 is an intermediate roll between the roll 1 and a front roll 3, all of which are mounted in bearings on an inclined plane and driven by an electric motor 5 via a speed variator 6. The roll 3 is driven via the variator 6 through gears 7, 8 and a V-belt and pulley drive 9, this drive being transmitted to roll 2 by gears 10, 11 which determine the R.P.M. ratio between the rolls 2 and 3. The feed roll 1 is separately driven from an extension of the output of the speed variator 6 by an adjustable pulley 12 mounted on the extension, a V-belt 13 and an adjustable pulley 14, which is mounted on a countershaft carrying a pulley 15, which transmits power to the roll through a V-belt 16 and a sun-and-planet reduction pulley 17. Thus, in operation, the overall speed of the rolls can be varied by the variator 6, while the R.P.M. ratio between the rolls 1, 2 can be varied by the adjustable pulleys 12, 14 within limits determined by those pulleys, which may be between 1:1-1 and 1:10 or more.
Patent GB-942079-A (GB)
Title: Production of granular zirconia products
IPC: C04B35/46
Filed: 1960-12-30
Abstract: Fused, low silica, granular zirconia is produced by heating a mixture of a silica-containing zirconium ore such as zircon or baddeleyite, carbon, and an oxide or oxide-forming compound of an alkaline earth metal, particularly calcium oxide or magnesium oxide, to at least 4500 DEG  F. in an arc furnace in the presence of nitrogen.  The resulting fused pig containing zirconium cyanonitride is subjected to oxidizing conditions at a temperature of at least 1500 DEG  F. in a muffler furnace or rotary kiln, whereupon the mass disintegrates into a granular zirconia. A ratio of 1/16 of stabilizing agent to zirconia is necessary to obtain 70% of the zirconia in the cubic form, and ratios somewhat above 1/8 are usually used to allow for possible loss.  To produce unstabilized zirconia the ratio of alkaline earth oxide to zirconia may be as low as 1/60 .  Crucibles may be produced from a mix of zirconia stabilized with a minor portion of calcium oxide, and a 2% aqueous solution of sodium pyrophosphite, by casting in a porous plaster mould, drying the crucible in air, and firing in an essentially neutral or oxidizing atmosphere at 3000 DEG  F.

Title: Recovery of oxytetracycline
Inventor: BRUNTON ROGER JOHN
IPC: C07C233/00
Filed: 1964-11-03
Abstract: Amphoteric oxytetracycline is liberated from its complexes with organic amines or 8-or-more-carbon-containing quaternary ammonium salts, by dissolving the complex in aqueous acid and treating the solution, in the presence of urea, so as to raise its pH, when free oxytetracycline is precipitated the complexes are of the kind precipitated in procedures for isolating oxytetracycline by addition to oxytetracycline fermentation broths of the said amines or ammonium salts.  The urea is preferably present in a proportion of at least 0.5 kgms. per 109 units of oxytetracycline activity; the pH of the solution, initially at 1.5 to 2.5, is raised to pH 4 to 6 by addition of, e.g., ammonium or alkali metal hydroxides.  The complex normally contains metallic ions, such as Fe or Ca ions which are preferably sequestered in or removed from the acid solution with ethylene diamine tetraacetic acid, tartaric acid, or citric acid, and with oxalic acid respectively. The precipitated oxytetracycline may be freed from any unchanged complex by washing with isopropanol. missing page 302

Title: Improvements in and relating to the generating of a bi-polar control voltage depending on the momentary storage content of a binary store
IPC: G05B19/23
Filed: 1963-11-14
Abstract: 1,031,740. Electric selective signalling. CONTRAVES A.G. Nov. 14, 1963 [Feb. 15, 1963], No. 44986/63. Heading G4H. A bipolar control voltage for a reversible appliance is determined by the states of bistable storage elements, one element determining the polarity and whether the other elements are taken in normal or inverted form to control the magnitude of the voltage. Thus, if the number in the storage elements is less than half the maximum possible number, the voltage is proportional to it in magnitude and positive, whereas if the number is less than half, the voltage is proportional in magnitude to the complement of the number and negative. In Fig. 1 (not shown), relays are set by manual switches to store three decimal digits, each in 1,2,2,4 code. The most significant relay connects a first line to a positive source or a second line to a negative source. Weighted resistors are connected through respective contacts of the other relays to one of the lines depending on the states of the relays. A correction resistor is also present to ensure in the appropriate case that the output voltage is the complement of 1000 rather than 999. The output voltage is limited by a Zener diode and used to drive a motor to produce a sequence of two-bit signals on a pair of lines repetitively. Use in a feedback positioning system is mentioned. Figs. 2 and 4 (not shown), show modifications.
