Title: Removal of VLF components from video signal - by adding inverted output of low-pass filter to cancel effects of haze and camera shock
IPC: H04N5/21
Filed: 1974-02-01
Abstract: A television system is provided with circuitry which improves the quality of the video signals obtained under viewing conditions which usually have resulted in poor quality pictures being obtained. The circuitry removes any very low frequency component which is superimposed on the video signal without significantly reducing the useful information content of the video signals. The undesirable low frequency component arises particularly when a hazy scene is viewed or when the camera is subjected to shock or vibration. The LF modulation signals are extracted by a low-pass filter and inverted before recombination. The system is particularly suitable for use before transmission so that only useful information is amplified and transmitted.

Title: Waste water purificn. by rotary bacterial bed - inhabiting tubes on rotor requiring reduced turning power
IPC: C02F3/08
Filed: 1974-02-06
Abstract: A biological treatment plant is claimed for the purificn. of waste waters, of the type in which the waste water percolates through a bacterial bed inhabiting multi-channel tube surfaces which are fixed to a rotating assembly for alternate immersion in the water and exposure to atmospheric air. Essentially, the axis of each tube lies in a vertical plane perpendicular to the axis of rotation and is tangential to the circle described by the centre of the tube. Conveniently, tubes are assembled in a number of bundles arranged in regular fashion around the periphery of the rotating assembly. This is a high capacity purificn. plant for waste waters of the partly-immersed, rotary biological bed type. The tube arrangement offers low resistance to passage through the water, so power requirement for rotation is also low. Tube bundles can be easily and inexpensively pre-assembled so that making up and servicing the rotor is simplified.

Title: High intensity ion currents - using a positively charged heated metal target for a neutral molecular beam
IPC: B01D59/44
Filed: 1974-03-18
Abstract: A high intensity ion current, partic. a beam of ions of uranium (cpds) e.g. for isotopic enrichment processes is produced by creating a high intensity jet of neutral molecules and directing this onto a metal surface, the normal to which is inclined to the direction of the molecular jet, the work of emission from the material forming the metal surface being of the same order as or greater than the ionisation potential of the molecules in the jet; and bringing the metal surface to a positive potential, to favour the expulsion of ions formed by the impact of the neutral molecules on that surface. Pref. the metal surface is heated and the molecules constituting the jet are pref. in the gaseous state. Much greater ion currents, e.g. exceeding several tens of Amperes, can be produced, so that the ion beams can be used in large scale prodn. of e.g. U-235.

Title: Fuel element has rods of varying enrichment - and corresponding varying pin diameters fitting holes in upper plate
Inventor: SMITH BART ALAN
IPC: G21C3/328
Filed: 1975-09-29
Abstract: A fuel cluster for a reactor core comprises a number of long fuel rods held between upper and lower anchor plates and having spacers at intervals; the upper end of each rod has an extension shaft, of a diameter smaller than that of the rod itself and varying according to the degree of enrichment of the fuel constituting the rod; the upper anchor plate contains cavities or passages, all of the same diameter, to restain the upper ends of the fuel rods; into these cavities, cylindrical plugs, of varying diameter according to the intended fuel rod for the particular location, are inserted. Pref., the extension shafts of fuel rods of high enrichment have a larger diameter than those of low enrichment, so that when the plugs are accordingly located, it is impossible for a high-enrichment rod to be inserted in the location intended for a low-enrichment rod. When drawing up a schedule of new fuel clusters for recharging a reactor, the final decision can be left to a fairly late date for the assembly required, in regard to enrichment, for each fuel cluster; it is then only necessary to arrange the variable diameter plugs in their appropriate locations to enable the cluster to be assembled. No special upper plates are required, since all can be of the same design.
