Abstract: 1,133,002. Sintered nuclear fuels of uranium dioxide. COMMISSARIAT A L'ENERGIE ATOMIQUE. 18 Feb., 1966 [22 Feb., 1965], No. 6867/66. Heading C1A. [Also in Division G6] Uranium oxide may be formed into fuel rods, with intergranular structure, i.e. having cavities or pores between the grains but substantially no pores within the grains, by adjusting the shaping pressure, the powder fineness and the rate of increase of temperature during sintering. In general increase of pressure, increase of powder fineness and increase of the rate of temperature rise facilitates the formation of the intergranular structure. The formed elements usually have a density from 88-96% of the theoretical density of N0 2 . Intergranular structure is defined as a microstructure essentially comprising ports distributed in the form of recesses at the grain joints and practically without communication with the outside, therefore of closed porosity. Fig. 4 shows intragranular structure, i.e. pores in communication, Fig. 5 shows intergranular structure. These were both formed under similar conditions except that the shaping pressure of Fig. 4 was 4 tons/cm.<SP>2</SP> whereas the shaping pressure of Fig. 5 was 6 tons/cm.<SP>2</SP>.

Title: Improvements in or relating to means for reducing the wringing pressure in warp sizing machines
IPC: D06B15/02
Filed: 1955-03-10
Abstract: Pressure between wringing rollers may be varied by a piston z moving centrally pivoted levers b supporting the ends of a roller a.  The pressure system comprises a three-way cock s, a gauge n, a pressure reducing valve m, a high-pressure container g and a pressure fluid reservoir i joined by a pump u, and jointed <PICT:0781324/IV (b)/1> rods f, f1 which may be moved by a cam e to rotate the cock s.  When running slowly the roller pressure is reduced by feeding fluid at say 7 atmospheres from the container g to the cylinder r via the reducing valve m.  If fluid at 4 atmospheres is required to reduce the roller pressure then the valve m is adjusted until the gauge n reads 4 atmospheres.  The cock s is then turned by movement of the cam e when the machine is switched to slow running which cam e lifts rods f, f1 to permit fluid to enter the cylinder r to move the piston z and levers b.  When running rapidly the weight of the roller a is the only pressure producer, the cock s being turned by movement of cam e and falls on rods f, f1 to allow the fluid to escape from the cylinder to the reservoir i.  Several wringing machines may be connected to the one container g.
