Title: Fast reactor fuel elements - with steel sheath contg boron to increase grain boundary strength
IPC: G21C3/07
Filed: 1972-03-22
Abstract: The fuel element consisting of a fissile material in a steel alloy sheath, contains 1-1000 ppm B in the alloy as grain boundary strengthening constituent B counteracts the destruction of the sheath material by fast neutrons. Natural B is usually suitable, but it is prefd. to use a lower B10 content (18.8%) esp. at higher B contents to minimise thermal neutron capture. The use of N and/or C, to form B nitrides, carbides or carbonitrides, gives further increase in the grain boundary strength.

Title: Method of storing data digitally - involves removing metallised areas from a metallised tape
IPC: G06K1/12
Filed: 1973-10-23
Abstract: The plastics film may be a band whose dimensions are compatable with the tape transport means of magnetic tape or cine appts. The information is recorded on the hand by removing the metallised layer to depict the digital characters which show up as transparent areas against an opaque background. Alternatively the digital characters may be formed by removing the metallised layer from the surface of the film, except in the area of the characters, so that these then appear opaque against a transparent background. The latter two methods of forming the digital characters may be used alternately in accordance with e.g. a telecommunication code.

Title: Lime recovery from (sugar ind) waste slurry - by heat treatment in suspension in rising hot air stream
IPC: B01J6/00
Filed: 1974-06-06
Abstract: The process comprises introducing the preheated slurry and a calculated amt. of added fuel into a hot combustion air stream (III), which is directed upwards, and mixing intimately with this, the velocity of (III) being high enough to keep the solid particles up to a certain size in suspension for a certain time. The stay time for larger particles is greater than that of small ones, so the large particles fall and are collected and discharge. Temp. of air stream and throughput are regulated so that the particles are heated at over 400 degrees C/s and remain in the combustion and reaction zone for 1 s, whilst the air ratio in the combustion reaction is >1.20 (1.40-1.60). The calcined particles are sepd. from (III) at a temp. below which the lime reacts with the CO2 contained in (III). The CaO prod. is suitable for re-use in sugar mfr.

Title: Low volume screw compressor - rotors are shaped for improved gas flow
IPC: F04C18/16
Filed: 1974-12-02
Abstract: A screw compressor for low volumes have rotors having a diameter which is large compared with the volume of gas admitted, the ratio between the head and foot diameters being low enough to give a value of the forward section of the gaps between the threads equal to the volume of gas admitted. The rotor teeth are shaped so that the ratio between the size of the teeth in the narrowest region between the teeth in the largest region is increased to between 0.5 and 1.5 for the female rotor, preferably 1. In a two stage compressor, the rotors of both stages are of the same O/D, the ratio between the head and foot diameters of the second stage conforming with respect to the volumetric flow of the two stages, being less than the ratio of the head and foot diameters of the first stage. The two stages are driven at the same speed, and their drive shafts are parallel, driven through gearing from a common shaft.

Title: Cyclone for sepg. dust from hot furnace gases - with two walls forming air-preheating and gas-cooling space between them
IPC: F23L15/00
Filed: 1975-04-18
Abstract: In the cyclone the space between the two walls constitutes a preheating space for the incoming air for combustion and a cooling space for the furnace gases. There may be baffles in this space, to ensure turbulent flow. Opt., in addn. to the two walls, there is a canopy in the sepn. space in the cyclone. Solids can fall between the edges of the canopy and the inner wall of the cyclone, into the space below the canopy. This space has an inlet and an outlet for air. The inlet is connected to the sapce between the walls and the outlet is connected to the pipe feeding air or oxygen to the furnace. The plant is simpler to construct, takes up less space and costs less than existing plants, because the furnace gases are cooled and the solids are sepd. in the same unit, where heat is transferred efficiently from the furnace gases to the combustion air or oxygen, and where the solids are cooled before being discharged from the separator. In the form with a canopy, solid particles are cooled by direct contact with air.
