Abstract: PCT No. PCT/GB87/00626 Sec. 371 Date Mar. 10, 1989 Sec. 102(e) Date Mar. 10, 1989 PCT Filed Sep. 7, 1987 PCT Pub. No. WO88/02111 PCT Pub. Date Mar. 24, 1988.A method for the rapid and sensitive analysis of heavy metal ores, especially those of gold and uranium, uses high-engery X-ray fluorescence spectroscopy. The invention is of particular interest for the measurement of samples from gold or bodies which typically have concentrations up to 10 ppm by mass. Preferred features include the use of an X-ray tube as a source, the counting of emitted fluorescence photons in energy bands selected to correlate with the characteristic x-ray fluorescence emissions of elements of interest, the excitement of the ore sample by irradiation with high energy bremsstrahlung radiation filtered through tin, the exploitation of polarization in analysis for uranium, the interposition of a platinum-group metal filter between the sample and the detector, and the use of high-purity germanium detectors. Techniques are described for the detection and elimination of inaccuracies due to the presence of certain interfering metals and correction for variations in sample density. Apparatus for use in the method of the invention is also disclosed and claimed.

Patent GB-882091-A (GB)
Abstract: 882,091. Selective punching machines. BEECH, H. B. May 27, 1958 [Feb. 25, 1957], No. 2710/57. Class 31 (2). [Also in Group XVIII] A machine for recording bets on races or private football pools comprises coin-freed means for printing a ticket with a number or date and for indicating, by punching or printing, once in each of a number of rows on the ticket, the operator's forecast of results. A ticket 13 taken from a magazine 84 is inserted in a slideway 12 against stops 20 so that it lies between a printing forme 24 and a removable pad 18 and between perforated die plates 15, 16. Punches 27 arranged in two vertical rows of four each are aligned with the die plates and behind the punches setting bars 34 are vertically adjustable so that a block 35 on each bar can be brought behind a selected punch in the row of four. The bars have pins at their upper ends, each engaging in an inclined slot in a series of strips each connected to a similar strip 63 with an external knob 64. Movement of a knob to a selected position, which may be indicated by 1, X, 2, as shown in Fig. 10, moves the corresponding selector bar so that the block 35 lies behind a selected punch and the strip is held in adjusted position by a roller 73 on a spring-loaded lever 71 engaging behind or between rollers 67 between the two strips. A spring-loaded presser block 31 can be moved to operate the selected punches by a roller 43 on a pair of levers 41 and by a lever 40, these levers being carried by a shaft 39 on which there is an external handle 57. Operation of the handle is normally prevented by the lever 40 engaging a stop 61 on a lever 49, but the stop is raised when a coin 55 inserted in a shoot 54 is pulled forward against a pin 51 by a pin 47 on a lever 46 linked to the lever 40. Just before the punches penetrate the ticket, a pin 30 on the presser plate pierces the ticket and holds it in place and simultaneously with the operation of the punches the printing forme 24 prints a changeable date and a suitable legend on the ticket through the medium of an inking ribbon 25. Catches or stops may be provided so that any of the ten selector strips can be rendered immovable. A mechanical counter may be provided for recording the number of times the handle 57 is operated and there may be several such counters, selected by an external pointer, so that several competitions may be run simultaneously on the same machine. In modifications, inclined levers with four notches are moved bodily sideways by the selector strip to position the setting bars, the tickets are separated from a web of paper fed from a reel, the web and reel being duplicated, if required, to give a copy retained in the machine and the punches and printing forme may be stationary and the ticket holder movable. Each vertical row of four punches may be replaced by a single punch hinged to a die block movable into any one of four vertically-spaced positions or coin-freed operating keys or handles may be related to one particular punch or a row of punches. Alternatively, a single row of punches may operate on a length of paper drawn from a reel and fed step-bystep past the punches.

Title: Inverter unit with improved bus-plate configuration
Inventor: YUJI NISHIZAWA
IPC: H02M7/00
Filed: 1991-03-14
Abstract: In an inverter, in order to reduce the effect of the distributed inductance contributed by conductors 7a, 8a used to connect DC smoothing capacitances 2 and switching elements 1, and thus the need for large snubber capacitances 9 to compensate for the distributed inductances. the conductors 7a, 8a are given a geometry and an orientation that causes the inductances to be minimized. The conductors 7a, 8a are of a bus-plate form, having a large area for improving heat dissipation, and an orientation so that the magnitude and direction of currents flowing through the bus-plates tend to minimize the effect of the distributed inductances. The bus-plates may comprise one or more separate conductive plates and may be shaped to provide slots (30, Fig 4) for viewing explosion proof valves (29) on the capacitors. The switching elements 1 may be IGBT, MOST or bipolar transistors. The inverter unit can be used for driving a motor with multi-phased currents, each of the phases being derived from a.c. input voltages that are applied to respective input terminals, rectified and smoothed by the capacitors 2 before being applied to parallel-connected switching elements 1 to develop each of the phased a.c. outputs. <IMAGE>
Patent GB-2242715-A (GB)
Title: Clutch assembly
Inventor: ELSNER ERNST
IPC: F16D47/02
Filed: 1991-04-04
Abstract: A clutch assembly employs components (4, 6) coupled together with a friction safety clutch (1), for load-dependent isolation of the power or torque in a drive line. To operate a driven machine briefly, even after the safety clutch has responded, an auxiliary clutch (12) is connected in parallel with the safety clutch. By means of this auxiliary clutch, a reduced torque can be transmitted for a short time so that it is possible to eliminate the cause of the safety clutch having responded and, in the case of a rolling mill, to prevent the mill being shut down. The auxiliary clutch (12) may be either a positive or friction clutch and may be switchable or constantly ready for operation. In a switchable embodiment the actuator is externally and non-rotatably disposed alongside the clutch assembly or integrated into the auxiliary clutch. The switchable auxiliary clutch may be constructed so that it can be actuated by a pressurised medium or electromagnetically. <IMAGE>

Title: Security enclosures
Inventor: MACPHERSON HUGH
IPC: E05G1/10
Filed: 1992-06-05
Abstract: A security enclosure comprises a first layer of an insulating material 16 extending over the whole of the area of the enclosure and carrying a linear electrically responsive element 18 on at least one surface. A low tensile strength layer 32 having lower cohesion than adhesion is located between the first layer of insulating material and the electrically responsive element. A second layer of insulating material 22 is adhered to and covers the electrically responsive element. The element is arranged in a configuration on the surface so dividing the surface that attempted penetration of the enclosure changes an electrical characteristic of the element, the change being detectable by an electrical circuit 50. An attempt to remove the second layer of insulating material to gain access to the element results in breakup of the low tensile strength layer and thus damage to the element and produces a detectable change in an electrical characteristic of the element. <IMAGE>

Patent GB-2276656-A (GB)
Title: Water supply isolation system
Inventor: SAGE-PASSANT PETER
IPC: E03B7/10
Filed: 1993-04-02
Abstract: A water isolation system comprises a valve (1) in a water flow line (10), with a latched solenoid to open or close the valve. A power source operates the valve with an electrical switch (2) causing pulsed actuation of the solenoid on operation of the switch. The solenoid is unpowered when the switch is not being operated. The switch (2) is located at a convenient point within a building to which the water is supplied, which point may be remote from the water flow line, such as adjacent a main entry/exit door to the building. Use of the system allows the water supply to be completely isolated when the building is to be unoccupied for even the shortest period of time. It also prevents excessive water loss and water damage when there is a burst pipe by being controlled at a point which is easy to reach and thereby switch off the system quickly. Finally, it can be easily closed to facilitate maintenance or replacement of any part of the water or heating system within the building. <IMAGE>
