Title: Improvements in methods for making uranium mono carbide articles
Inventor: ACCARY ANDRE
IPC: C01B31/30
Filed: 1960-10-31
Abstract: An article of uranium monocarbide is produced by heating an approximately stoichiometric mixture of carbon and uranium powders in a mould at or near vacuum pressure, from a first temperature at which uranium hydride (UH3) decomposes (about 250 DEG C.) to a final temperature at which solid phase diffusion of the uranium monocarbide takes place (about 1200 DEG C.), the heating being carried out at different rates between successively higher temperatures, and the article being then cooled and removed from the mould.  Prior to the heating the mixture of powders may be mechanically packed in the mould, e.g. by vibration, until its density is 5 grams/c.c.  The heating may comprise the following steps:-(a) preheating from ambient temperature to the initial temperature of about 250 DEG C., e.g. at 100 DEG C. per hour, (b) heating from about 250 DEG C. to about 450 DEG C. at a fast rate, e.g. 200 DEG C. per hour, (c) heating from about 450 DEG C. to about 900 DEG C. at a slower rate, e.g. 100 DEG C. per hour, and (d) finally heating to about 1200 DEG C. at a fast rate, e.g. 200 DEG C. per hour.  Stage (c) may be divided into two parts, i.e. heating from 450 DEG C. to 750 DEG C. at 100 DEG C. per hour and then from 750 DEG C. to 900 DEG C. at 50 DEG C. per hour. The article is maintained at the final temperature for about 2 hours and may be cooled at the rate of 300 DEG C. per hour.  The density of the finished product is about 7,5 grams/c.c., and the density may be further increased by electrothermal treatment, e.g. by electromagnetic induction, by the Joule effect, or by treatment in tanks in which the article acts as an electrode.

Two superposed quadrilateral flexible sheets 1, 2 (Fig. 2) joined at some or all of their edges ab, bc, cd, da and formed at two or more corners with notches such as aEa are formed into containers by joining the lips such as aE, aE, forming each notch. The notches are symmetrical about the bisectors EF, EG of the quadrilaterals and can be secured together with the container folded flat as in Fig. 3, by refolding the container along the lines HFGI (Fig. 2) with the portions ad, be pushed re-entrantly into the container. All four corners may be notched and joined, as indicated in Fig. 2, or alternatively this may be done at two corners only to form the bottom of a bag such as is shown in Fig. 16. In forming this bag the intermediate configuration shown in Fig. 14 can be reached by securing together two sheets cut to the form of Fig. 13 and refolding the resulting tube along the lines AB, DC. Reentrant and external gussets 17, 18 (Fig. 10) may be provided to receive one or more internal partitions 19 which may be perforated and may be formed in two parts stuck together. The partition 19 is secured in place before the upper and lower portions of the bag, including the notches such as aEa and the edges such as ab, are secured together. The bag may be formed of plastics, or, as shown, of rubberized fabric with the seams secured by adhesive strips such as 3 (Fig. 2) and 20 (Fig. 10). The two sheets shown in Fig. 2 may be folded from a single sheet, making one of the seams ab unnecessary. A spout for filling the bag may be formed by including in the seams a tapering rubber tube 27 (Fig. 13) provided with a metal insert 29 to receive a stopper 31 (Fig. 16). An outlet spout may be similarly secured. Handles or lifting shackles may be secured to fabric tabs 14 (Fig. 7) stuck to the walls of the bag over adhesively secured metal strips 13. The webs 14 may be secured at straight portions of the seams between opposite edges of the notches aEa (Fig. 2). The handle shown in Fig. 2, which is a ring 32 is held between two walls 25 may receive a lifting ring so that the aperture 26 can be omitted. According to the Specification the bag may serve to contain fuel towed underwater.

Abstract: 920,965. Coiling. K. HACK. Oct. 25, 1961 [Oct. 25, 1960], No. 38141/61. Class 83 (4). Method of making coil springs of the type wound from continuous wire stock and provided with an eye at each end is characterized in that the wound body of a spring is seized by means which move it axially after severance from the wire stock, whilst at the same time the commencing coil of the following spring is wound, the last coil of the wound spring and the said commencing coil of the next following spring being then simultaneously bent over as eyes. Wire 2 is fed by rolls 1 through a guide 3 to coiling tools 4, 4<SP>1</SP> which form the wire into a helical spring 5. After a predetermined number of turns has been wound switch means stops the feed rolls 1 and actuates a knife 8 which cuts the wire from the supply against a mandrel 9. Shortly before the wire is cut jaws 7 close on the spring 5 and, after the wire is cut, they withdraw the spring axially a short distance, the knife 8 returning to its initial position and the rolls 1 starting again to feed wire to wind the first coil 10 of the next spring. The end coils 10 and 11 of the two springs are then pushed down by a pre-bender 12, Fig. 5, towards bending tools 13 which then pivot to bend up the end coils 10, 11 against the member 12, Fig. 6. The jaws 7 are then opened and the spring 5 dropped out. As the tools 12, 13 return to their original position winding of the next spring commences.

Patent GB-371360-A (GB)
Title: Improvements in the manufacture of filaments, threads and the like
IPC: D01D4/02
Filed: 1930-12-20
Abstract: <PICT:0371360/IV/1> <PICT:0371360/IV/2> <PICT:0371360/IV/3> In a wet or semi-wet spinning process, particularly for cellulose acetate or other esters or ethers, a spinning solution is extruded through a coagulating medium to form a plurality of filaments or the like in such a way that these carry away insufficient liquid to cause them to cling together.  Thus the filaments may be extruded through a liquid film of limited thickness.  By this means spinning speeds of 150-400 or more metres per minute can be attained.  The coagulating liquid should be less volatile than the solvent of the spinning solution. Preferably also it should not have a very great precipitating action unless a mat effect is desired.  It is advantageous to use a liquid of high plasticizing power as described in Specifications 340,324 and 340,325, for instance a 25-65 per cent aqueous or alcoholic solution of ethyl lactate, diacetone alcohol, diethyl tartrate, mono- and di-acetin, dioxane, lactic acid, and the like, or plasticizing agents, e.g. tricresyl phosphate, or xylene monomethyl sulphonamides, with or without solvents or non-solvents for the cellulose derivatives such as an ester or ether.  In one form of apparatus, a hemispherical spinning nozzle 10, Fig. 1, with a ring of perforations 13, is kept covered with a film of coagulating liquid by a surrounding trough 12, the inner edge of which is notched. In a modification the nozzle is of triangular vertical section and has a line of holes along its downwardly-directed apex.  Fig. 7 shows a nozzle of the type described in Specification 355,720.  It has an annular trough portion 24 with a ring of holes 25 supplied with spinning solution by ducts 26.  An interior tube 27 supplies coagulant to a series of holes 28 in the surface inside the ring of spinning holes.  Coagulating solution may also be supplied simultaneously from the outside and the inside of a ring of spinning orifices.  For upward spinning, the nozzle 19, Fig. 5, may be concave as shown, flat, or convex, the liquid being supplied from the outside of a ring of orifices when the face is concave or from the inside when it is convex; or the spinning holes may be in a line.  The nozzle 19 may be swivelled so that spinning is initially effected downwards.  After evaporation of the solvents and coagulating liquids, preferably in an ordinary metier, the filaments may be wound with or without twisting. Specification 198,023, [Class 2 (ii), Cellulose &c.], also is referred to.
