Abstract: 1,171,856. Nuclear power plant. ALLM€NNA SVENSKA ELEKTRISKA A.B. 30 March, 1967 [31 March, 1966], No. 14529/67. Heading G6C. In a boiling water reactor, circulation of the water through the core is effected by jet pumps through which water is urged by pumps external to the pressure vessel. Two external flow paths are provided, one through a turbine and one, which includes the jet pumps, independently controllable to permit adjustment of the water flow through the reactor. The latter effects regulation of the reactor temperature and thus also of its power output. Light or heavy water may be employed and in the latter case a large range of control is provided by the change in the moderating effect of the water with temperature.

Title: Process for recuperating part of useful metals in soiled copper raw materials
Inventor: SA HOLMSTROEM
IPC: C22B15/00
Filed: 1985-09-26
Abstract: The invention relates to a method for recovering the valuable metal content of a mix of contaminated copper raw materials, of which materials at least one is sulphide bearing, and which contain one or more impurities forming the group arsenic, antimony, bismuth, mercury, tin, chlorine and other halogens. The invention is characterized by adjusting the halogen content of the mix so that it is substantially at least stoichiometric in relation to remaining impurities in the group, whereafter the mix is charged to a furnace in which melting can take place and in which the mix is heated to at least 500°C, but beneath the melting points of respective ingredients of the mix, while maintaining good contact with hot gas therewith to expel substantially all of the aforementioned impurities present. The mix is then heated to completely smelt the ingredients present, to form a slag and a copper matte, which latter contains the valuable metal content, whereafter this valuable metal content is recovered with the aid of a suitable, conventional method.At least one of the copper raw materials present in the mix comprises suitably a halogen-bearing valuable-metal containing product, for example chlorine-bearing ash or slag.

Title: Location method and panel pressing apparatus
Inventor: BROWN GORDON CLIFFORD
IPC: B21D1/06
Filed: 1993-10-13
Abstract: The invention concerns a method of locating and repairing dents in motor vehicle panels (10). The initial step in the method is to locate the dent in the panel (10). This is done by positioning a magnet (20, 40) and a metal ball (18) on or adjacent to opposite surfaces of the panel (10) so that the magnet (20, 40) and ball (18) attract one another through the panel (10). The relevant one of the magnet or ball is moved to the location of the dent on one side of the panel with the result that the other of the magnet or ball moves to the dent on the other side of the panel. The magnet (40) is typically carried by a mechanical pressing tool (Figure 2) which can then be used to lever out the dent by working the metal around the dent. <IMAGE>

Title: Dispensing of beverages
Inventor: JOHNSON MARTIN STANLEY
IPC: F16K5/04
Filed: 2000-03-16
Granted: 2001-03-14
Abstract: The present invention is a flow rate control valve through which a liquid flows and from which the liquid is dispensed. The flow rate of the liquid is sensed and that information is sent to a microprocessor based control. The control operates a drive of the control valve so as to vary the resultant rate at which the liquid is dispensed therefrom. The drive operates a piston closure member that extends closely within a cylindrical passageway. The passageway has an inlet end and an outlet end and the drive operates the closure member in the passageway to a plurality of positions from a first position at the inlet end and a second position at the outlet end. The wall of the passageway defines at least one groove having a transverse cross-section that increases in area in a downstream direction from the passageway inlet to the passageway outlet or in an upstream direction from the passageway outlet to the passageway inlet, whereby movement of the closure between the first position and the second position varies the flow rate of the liquid through the control valve as a function of the cross-sectional area of the groove.

Title: Metal detector
Inventor: BRITTON ANDREW MICHAEL
IPC: G01V3/10
Filed: 2000-04-20
Granted: 2004-07-07
Abstract: A metal detector has a circular excitation coil ( 10 ) through which foodstuffs to be tested ( 65 ) pass, on a conveyor belt ( 40 ). The excitation coil ( 10 ) is excited by a stable oscillator ( 50 ) and the lines of flux generated by the excitation coil ( 10 ) link two receiver coils ( 20, 30 ) equidistantly spaced either side of the excitation coil ( 10 ). As a foodstuff ( 65 ) having a foreign ferromagnetic or electrically conductive object therein passes through the receiver coils ( 20, 30 ), a voltage is induced in them. This induced voltage is phase compensated. The change in amplitude or frequency of the oscillator ( 50 ) as the foodstuff ( 65 ) moves through the excitation coil ( 10 ) is also passed to the processor ( 70 ) which removes the artifacts from the detector signal caused by the volume of the foodstuff ( 65 ) itself. The resultant signal, which was previously swamped by the effect of the volume of the foodstuff itself, can then be detected and the foodstuff can be removed from the conveyor ( 40 ).
