Title: An annular fuel element for a nuclear reactor
Inventor: FUHRMANN ROBERT
IPC: G21C3/38
Filed: 1967-05-26
Abstract: 1,121,979. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. 26 May, 1967 [27 May, 1966], No. 24502/67. Heading G6C. An annular fuel element for a natural uranium reactor cooled by circulation of CO 2  gas in the same direction inside and outside the element comprises a tubular slug of nuclear fuel covered with external and internal cladding, both of which have fins arranged in chevrons and are connected by annular plugs, the external cladding and plugs being made from a Mg-based alloy and the internal cladding from Zr or a Zr-based alloy having a higher hot strength than the Mg alloy. Suitable Zr alloys are Zircaloy ATR (containing, by wt., 0À5% Cu and 0À5% Mo), Zircaloy AJR (containing, by wt., 1% Cu and 1À5% Mo) and Zircaloy-2 (containing, by wt., 1À5% Sn and small additions of Ni, Cr and Fe). The fins on the internal cladding are preferably shallower than those on the external cladding. The external cladding may also have longitudinal partitions for centering the fuel element in a coolant duct. An annular disc of thermally insulating material resistant to creep when hot (e.g. a ceramic) is interposed between each plug and the fuel. The fuel is covered with the cladding members which are then forced against the fuel by any suitable method, e.g. hydraulic cladding after temporary plugging. The permanent plugs are then attached. The cladding members are preferably anchored on circular grooves in the fuel to prevent a ratchet effect during thermal cycling. The plugs are joined to the external cladding by arc-welding in an argon atmosphere or by electron beam welding and to the internal cladding by a process similar to that described in Specification 1,099,025.

Abstract: 296,307. Weiller, P. L. Aug. 27, 1927, [Convention date]. Pistons.-In a radial-cylinder internal-combustion engine each cylinder and piston are cut away as at 1<a> and 11<1>, Fig. 3, so that the next cylinder end 2<1>, Fig. 2, may project into the first-mentioned cylinder. As a consequence the over-all dimensions of the engine is reduced. The second mentioned cylinder is also recessed as at 2<a> at its projecting part to accommodate the adjacent connecting rod.

Title: Improvements in or relating to signalling systems
IPC: G08C19/02
Filed: 1950-10-09
Abstract: 691,392. Electric correspondence control systems. BAILEY METERS & CONTROLS, Ltd. Oct. 9, 1950 [Oct. 8, 1949]. No. 24594/50. Class 40 (i). [Also in Group XXIX.] Relates to transducers for converting variations in the magnitude of a first physical quantity into corresponding variations in the magnitude of a second physical quantity comprising a rotable member subject to opposing torques proportional to the magnitude of the first and second quantities, the magnitude of the second quantity being controlled by a device positioned by said member thereby balancing said torques. According to the present invention the first and second quantities are electric current (or voltage) and fluid pressure, Fig. 1, or vice-versa, Fig. 2 (not shown), the electric quantity being applied to the control winding of a magnetic fluid clutch to produce a corresponding torque. As shown a variable electric current is applied via leads 8 to the control winding of a magnetic fluid clutch 1 coupled to a constant speed electric motor which applies to a lever 3 pivoted at 9 a counterclockwise torque proportional to the current and the lever positions the stem 5 of a pilot valve 4 of the type disclosed in Specification 425,507, [Group XII], to control the air pressure in a pipe 10 connected to bellows 2 which apply a clockwise torque to the lever so that the lever assumes a resultant position such that the two opposing torques are balanced,. the pressure in pipe 10 being then proportional to the input current. In the converse arrangement, Fig. 2 (not shown), the input air pressure is applied to the bellows and the lever 3 positions the wiper of a variable resistance connected in series with the clutch control winding and a D.C. or A.C. voltage source so that the resultant current is proportional to the pressure in pipe 10. The magnetic fluid clutch, Fig. 3 (not shown), comprises driving and driven members of magnetic material separated by a fluid containing particles of magnetic material whose effective viscosity increases when subject to a magnetic field thereby increasing the torque transmission.

Patent GB-490972-A (GB)
Title: Improvements in the treatment of water
IPC: C02F1/00
Filed: 1937-09-13
Abstract: To remove fluorides from water the water is subjected to the action of materials which are capable of removing the fluorides from water and which, when they are exhausted can be regenerated for treatment of further water by successive treatments with dilute alkali and dilute acid.  As examples of materials for treating the fluoride containing water dried granular metallic oxide gels are mentioned such as hydrated ferric oxide and hydrated alumina: chromium borate, mixed oxides of iron and manganese, bauxite, bog iron ore and activated carbon may also be used.  Silica is generally removed with the fluorides.  In operation the fluoride removing material is preferably employed in pervious beds and the water is passed therethrough till the beds are exhausted: the beds are then subjected to the double regenerating treatment, solutions of an alkali such as caustic soda, or ammonia, and then of an acid such as acetic, with or without sodium acetate, sulphuric acid, hydrochloric acid, or salts which hydrolyse to give acids such as aluminium sulphate, ferric chloride and ferric sulphate, being passed through them, the beds being washed between and after the treatments with raw water.  Saline water containing fluorine compounds which has been treated with a hydrogen ion exchange substance and so rendered acidic may be subjected to the action of the material for removing fluorine compounds.

Regulating.-A blade-wheel, applicable as a turbine, turbine pump or propeller, carries oscillating blades M on pivots P rotating about a centre 0 in the direction K, the blades being controlled so that radius vectors S drawn from the points P perpendicular or nearly perpendicular to the blades always intersect in a point N lying inside the circle K. For this purpose the blades may be rigidly connected to rods passing through a sliding-rocking guide arranged at the point N.. Regulation and reversal are effected by displacing the point N either around the circle of radius O N or along its diameter N N<1>, or by a displacement combining both these movements.

[Also in Division G2] A light source 28 is placed between two adjacent light-transmitting containers 16, 22, of liquid toner and toner intensifier for replenishing a developing tank 12 in an electro-photographic apparatus, such that when the liquid level in either container reaches a predetermined low-level, the light from the source, unimpeded by the presence of the toner or intensifier, can shine through the container on to a light receiving means 30, 36, to provide a signal outside the body of the apparatus. The light recipient means may be light guides 30, 36 having lower inclined faces 32, 38, for reflecting the light to the upper visible end. Where the predetermined low-levels of the containers are different, a light baffle prevents direct transmission through the upper part of the container with the lower low-level. The light-transmitting containers may be transparent or translucent e.g. of polypropylene.
