Title: A yarn storing and feeding device for textile machines
Inventor: ROSEN KARL ISAC JOEL
IPC: B65H51/22
Filed: 1970-02-25
Abstract: 1,259,931. Yarn storage and feeding device. K. I. J. ROSEN. 25 Feb., 1970 [26 Feb., 1969], No. 9123/70. Heading DIJ. A yarn storing and feeding device for feeding a yarn from a bobbin to a working place on a textile machine comprises a storing drum 3 for receiving a yarn supply V and a control ring 6 for limiting the supply of yarn stored on the drum, the control ring 6 having radial arms 6a extending through longitudinal openings 4 in the wall of the drum and causing the yarn supply V to be fed along the wall of the drum, the device being characterised in that the outer ends of the arms 6a are connected by a closed ring 9 which surrounds the wall of the storing drum 3. The ring 9 is constituted by a web sloping upwards and outwards from the ring 6, in the direction opposite to the feed of the yarn supply V. The control ring 6 is inclined about the axis 5 and is spring urged in the inclined position. The control ring 6 preferably comprises a one-piece construction consisting of a circular plate with a deflected outer edge within which is arranged a circle of trapezium-shaped recesses between which are defined the arms.  In operation, yarn F is fed from a bobbin to the storing drum 3 which is preferably rotated by an electromotor 11. The inclined control ring 6 feeds the yarn on to the surface of the drum and the yarn supply V moves down the wall of the drum. The closed ring 9 prevents snagging of the yarn on the arms 6a. When the build-up of yarn supply V overcomes the spring pressure on the control ring 6, the ring 6 is pushed back from its inclined position and operates a switch to stop the electromotor 11. Yarn is drawn off from the yarn supply V and when the spring pressure on the control ring is sufficient to return the ring to its inclined position, the ring tilts and operates a switch to start the electromotor 11. This arrangement is suitable for intermittent yarn demands. The drum 3 need not be rotated, and the yarn could be fed from the yarn supply V continuously.

Title: Recovery of plutonium
IPC: G21C19/46
Filed: 1944-05-17
Abstract: Plutonium is recovered from an aqueous solution in which it is present together with uranium or fission products or both, by preferential adsorption of plutonium on diatomaceous earth, fuller's earth, silica gel, or magnesium silicate. Neutron-irradiated uranium may be dissolved in nitric acid and the solution contacted with the adsorbent, preferably at a pH of 2.3-3.7.  The concentration of uranyl nitrate in the solution is preferably below 30 per cent. Plutonium may be eluted from the adsorbent with 6N nitric acid of the fission products, a high proportion of columbium is adsorbed, lesser amounts of zirconium, and very small amounts of other fission products, e.g. barium and lanthanum.  To separate columbium and zirconium from plutonium, the plutonium may be precipitated in its lower oxidation state with fluoride ion; alternatively the plutonium may be eluted from the adsorbent with ammonium carbonate solution, leaving some fission products behind.  Experiments are described showing (a) the suitability of diatomaceous earth for re-use as an adsorbent after elution with nitric acid; (b) the effect on the amount of plutonium adsorbed of the pH of the aqueous solution and the concentration of uranyl nitrate; (c) the maximum pH to which uranyl nitrate solutions of different concentration may be raised without causing precipitation; (d) the raising of the pH of the first portion of a solution passed through a column of diatomaceous earth; (e) the strength of acid necessary for elution of the plutonium; (f) the effect of bombardment by deuterous of the diatomaceous earth adsorbent; (g) the amounts of plutonium and fission products adsorbed on a column of silica gel.

Title: Stop mechanism in connection with the thread securing the weft in needle looms
IPC: D03D47/46
Filed: 1937-04-05
Abstract: 492,054. Loom stop-motions. CRABTREE & SON, Ltd., D., and FELTON, W. April 5, 1937, No. 9549. [Class 142 (i)] The selvedge thread inserted through the weft loops by a shuttle carried by an oscillating arm 2 on a shaft 2a is engaged by a wire member or feeler 5 on an oscillating shaft a, which causes loom stoppage if the selvedge thread is broken &c. Periodically a cam 2b on the shaft 2a moves endwise a shaft b against spring action, a projection b<3> on a member b<2> then engaging a projection a<3> on a member on the shaft a, which is thereby turned to lower the feeler. Afterwards a counterweighted lever 8 raises the feeler by means of lever mechanism and if the selvedge thread is absent so as not to interfere with this movement the lever end 8f moves into the path of a lay projection. The arm 8b carrying the pivot of the lever 8 is rocked, and a projection on a shaft 9 disengages the knock-off handle and stops the loom. By varying the counterbalancing weights 8d on the lever 8, the pressure exerted by the feeler on the selvedge thread may be varied.
