Title: Improvements relating to flux scanning equipment for nuclear reactors
Inventor: JERVIS MAX WILLIAM
IPC: G21C17/10
Filed: 1957-10-18
Abstract: 866,514. Nuclear reactors. A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd. Oct. 8, 1958 [Oct. 18, 1957], No. 32617/57 Class 39(4). The neutron flux density distribution in a nuclear reactor is measured by measuring the activity induced in a wire or rod 5 (e.g. of tungsten) lowered into and then withdrawn from a channel in the reactor core. The error caused by the finite time of insertion and removal of the wire is allowed for by modifying the output of the detector which measures the activity in accordance with the distance along the wire of the detector. The modifier may be a graded or cam-driven variable resistor driven by the movement of the wire. Measurement is carried out by lowering the wire at 5<SP>1</SP> past the detector 23 (e.g. an ionisation chamber) in a well in the reactor shield.

Filed: 1973-12-18
Abstract: 1433410 Tyres CATERPILLAR TRACTOR CO 9 July 1973 32674/73 Heading B7C A tyre comprises a tread formed with a plurality of circumferentially spaced bars 13 extending substantially axially of the tyre and slots 14 between the bars which are each tapered to diverge axially outwardly towards an adjacent sidewall of the tyre, and a circumferential deflector ring 16 at the junction of each sidewall and the tread projecting axially outwardly beyond the sidewall so as in use to deflect matter at the footprint of the tyre tread away from the sidewall and protect the latter. In the illustrated embodiment two separate series of bars 13 are provided each adjacent a respective sidewall with the bars of one series being circumferentially staggered with respect to those of the other. A central circumferential rib 17 between the two series of bars 13 may have an axial width C equal to <SP>1</SP>/ 3  of the axial width of the tyre at the rings 16. The circumferential extent D of each bar 13 may be 1À5 times the circumferential extent E of a slot 14. As illustrated in Fig. 3, when the tyre is in an unloaded condition of operation the radially outer surface 19 of each bar 13 makes an angle Y of 25 degrees with a horizontal ground surface G, the axially outer surface 20 of each bar makes an angle Z of 70 degrees with the surface G, and the bottom surface 18 of each slot 14 makes an angle X of 35 degrees with the surface 20 of an adjacent bar 13. Upon loading of the tyre to the point where the angle Y is reduced to zero the angle X remains approximately constant and the angle Z changes to 55 degrees.

Abstract: 1278630 Rolling MANNESMANNROKREN-WERKE GmbH 30 June 1969 [5 July 1968 31 May 1969 (2)] 33005/69 Heading B3M A method of rolling tubes in a stretch reduction mill to produce a tube whose ends are of the same thickness as its middle portion comprises rolling the ends through roll stands whose roll speeds are different from the speeds used to roll the middle portions, the percentage differences for each stand being progressively greater from one end of the mill to the other. In rolling the leading edge of a tube the roll stands have their speeds reduced by, e.g., 50, 45 ... 0%, as indicated in phase 1 of Fig. 3 and this is maintained until the whole of the leading end (shaded portion) has entered the mill thereafter the roll speeds of the stands are increased successively as indicated in the Figure. In rolling the trailing end of the tube the speed of all the rolls is first reduced by say 50% then those rolling the middle portion are increased in speed relative to those rolling the trailing end portion, the increases being stepwise as successive roll stands commence rolling the trailing edge portion until the stand speeds are as shown in Fig. 3 ready to receive the leading end of the next tube to be rolled.

Abstract: 1,261,907. Rotary distributers. L. SHARPLES. 23 Sept., 1969 [16 July, 1968], No. 33829/68. Heading H1N. [Also in Division F1] In or for a fuel injection system of an internal combustion engine, a unit (shown in Fig. 1) is adapted to be mounted between the usual ignition distributer and its drive, the unit including bus-bars 6 electrically connected to the injector solenoids 9, Fig. 2 (not shown), with electrical current collectors 12 between the busbars 6 and a rotary segmental pulse distributer 13, the collectors 12 being caused to have motion axially of distributer 13 responsive to engine speed. Pulse distributer 13 comprises an insulating bush 14 with an insulated neutral segment 15 and a conductive segment 16 earthed to shaft 3 by pin 17, segments 15 and 16 being separated by gap 18. Bus-bars 6 are mounted in housing 1 and provided with terminals 7. Collectors 12 each comprises two spring loaded carbon brushes mounted in the skirt 11 of a piston 10 spring urged downwards by spring 25 the tension of which can be adjusted by screw-threaded ring 26 which bears on pins 27 bearing on a ring bearing on top of spring 25. The space above the piston 10 is connected by a union 23, Fig. 4 (not shown) in the top wall of the housing to the engine manifold. With a closed throttle valve, spring 25 urges piston 10 to the bottom of the housing 1, and no current will flow since collectors 12 are bearing solely on neutral segment 15. Opening of the throttle valve induces the piston to rise due to reduction of pressure in the space above the piston 10 created by depression in the engine manifold. As piston 10 rises, collectors 12 traverse both segments 15 and 16 completing an electric circuit for each solenoid as its collector traverses conductive segment 16. As piston 10 rises the pulse length of the current through the solenoid will lengthen to supply a richer mixture. Cold starting of the engine is accomplished by an L-shaped lifting device 28, Figs. 4 and 5 (not shown), below the piston which is operated normally through linkage and/or thermostatically to assist the rise of piston 10.
