Title: Preparation of dense uranium oxide
IPC: G21C3/62
Filed: 1964-03-10
Abstract: Dense UO2 bodies are produced by a process comprising compacting a UO2 powder having a surface area per unit weight of 1-18 sq. metres/gm., sintering in an atmosphere of steam at 1100-1450 DEG  C. and then subjecting the sintered body while above 1000 DEG  C. to a hydrocarbonaceous reducing gas which is free of oxidizing gases and contains up to 25 volume per cent of hydrogen until the O/U atomic ratio is below 2.025.  The reducing gas can be a liquefied petroleum gas (e.g. propane, butane) or natural gas which has been partially burnt. The UO2 starting material may be any sinterable powder having an O/U atomic ratio from 2.000-2.25 and particle size of 1 micron and is preferably prepared by the ammonium diuranate route.  The compacted body may be heated to 300 DEG  C. in an inert atmosphere (e.g. CO2, N2, A) or in an hydrocarbonaceous gas atmosphere having less than 3 volume per cent hydrogen and heated to sintering temperature in a steam atmosphere.  The sintered and reduced body may be cooled in a hydrocarbonaceous gas atmosphere having less than 3 volume per cent hydrogen or from 1000-300 DEG  C. a steam atmosphere may be used.

Title: Method and device for manufacture of hollow bodies with stressed reinforcement
IPC: B28B21/18
Filed: 1951-05-03
Abstract: 708,729. Reinforced concrete. HEIDENSTAM, E. J. VON. May 3, 1951, No. 10428/51. Class 20 (4). [Also in Group V] Relates to a method of casting pipes and other hollow bodies of concrete with pre-stressed reinforcement, in which after the concrete has been cast in an outer mould but has not yet solidified and acquired strength it is subjected to a lateral pressure directed outward to stress the reinforcement. According to the invention the reinforcement in the stressed concrete is held in its stressed position by a filling material such as sand or clay, which is filled into the cavity of the concrete body and compressed there, the concrete body being then removed, together with the compressed sand &c. from the outer mould and permitted to solidify. The mould is thereby quickly freed for further use. Fig. 1 shows a concrete pipe 1 being cast between an expansible mould 8 and an elastic tube 4 filled with sand or the like 5. A vibrator 12 operates within the sand and compressed air is forced into the tube through inlet 70, this resulting in expansion of the pipe and stressing of the reinforcement 2, 3 whereupon the mould is taken away. In Fig. 2 the pipe 1 is cast between an expansible outer mould 8 and an elastic tube 4 which is disposed between concentric hopper-like members 17, 18 which are raised as casting proceeds, sand being introduced into the tube. When the members have reached the dotted-line position the member 18 and the vertical reinforcement 2 are secured to a ring 20, and the tube and pipe are expanded by air or water forced in under pressure through inlet 70. A central pipe 24 carried by a base part 22 may be vibrated. Fig. 3 shows an arrangement for the continuous casting of pipe. Here the concrete, descending continuously from a hopper 4, is de-watered by compression between outer mould members 34 and an elastic member 33, the pressure being applied by water forced into the space between member 33 and a plate 36. The de-watered pipe descends and is forced out against a flared mould 8 by pressure applied by a rotating screw 40 or a ram) through sand 5. An elastic sheet may be inserted between the pipe and the sand. The casting may be carried out horizontally.

Abstract: 799,313. Soldering. TEICHEIRE, R. J. A. April 5, 1956, No. 10430/56. Class 83 (4). An electric soldering iron comprises a bit 1 mounted on one end of a shank 4 having a casing 5 at the other end for housing the end of an electric cable 6, a handle 8 having an axial bore with a part 10 tapering towards the bit end of the iron, the bit, shank and casing being slidable in the handle and the casing 5 having a diameter greater than the diameter of the narrow end of the bore part whereby it wedges in the bore when the bit is moved from its inoperative position adjacent the narrow end of the bore to its operative position remote from this end. The copper bit is secured by a screw 3 to a casing 2 containing the heating element and the shank, of stainless steel tube, encloses the leads to the element. The casing 5 is tapered in the opposite sense to that of the bore part. The bit, casings 2, 5 and shank may be retracted into the wooden handle until the screw 3 engages the belled mouth 9 of the handle and may be pushed forward until the casing 5 wedges in the bore.

Title: Capacitor foils
IPC: H01G13/00
Filed: 1973-03-05
Abstract: 1408075 Capacitors SIEMENS AG 5 March 1973 [6 March 1972] 10507/73 Heading H1M A composite foil for manufacturing capacitors comprises two superimposed dielectric foils each having a metal coating thereon, each coating extending to an opposite edge of the composite foil, an unmetallized margin being left at the other edge of each dielectric layer, the layer edges being so formed or arranged that when the composite foil is wound into a roll, the edge zone of each metal coating is not completely covered by the adjacent dielectric layer. As shown in Fig. 1, two dielectric strips, each a multiple of a composite foil width, each bear metallized bands 5 separated by metal-free zones 3 and a row of circular perforations are made along the centre line of each zone 3. The strips are superimposed so that the centre lines of zones 3 in one strip lie over the centre lines of bands 5 in the other, and caused to adhere together, and the assembly is cut along lines, e.g. 6 and 7 to form the composite strips. The semicircular indentations in the metal-free edges of the cut dielectric strips leave corresponding portions of the adjacent metal layer uncovered in a roll wound from the strip, which portions are accessible by the Schoop layer applied to the roll end. Alternatively (Fig. 2) a narrow strip is removed by cutting along lines 14, 15 about the centre line of metal-free band 13, and cut 16 is made along the centre line of metallized bands 12. When the cut strips are superimposed in the relative disposition shown in Fig. 2, the edge zone of each metallized coating extends beyond the adjacent dielectric edge, and is accordingly not covered by it in a roll. The composite foil may be wound on a large diameter substrate to form a mother capacitor from which individual stack capacitors may be severed.
