Title: Nuclear reactors
IPC: G21C1/12
Filed: 1973-06-01
Abstract: 1427620 Fuelling reactors NUCLEAR POWER CO (WHETSTONE) Ltd 21 May 1974 [1 June 1973] 26233/73 Heading G6C In a nuclear reactor, especially a high temperature reactor, having a core 20 of parallel columns 21 of moderator blocks of hexagonal cross-section within a pressure envelope 37, the envelope is provided with refuelling standpipes 23 each having its axis coincident with the common vertex of three adjacent columns of an associated group of twelve columns, consisting of three columns and the nine columns which immediately surround them, and the associated refuelling machine comprises a probe arrangeged to be introduced into the pressure envelope through the standpipe and carries a radially displaceable coupling means capable of engaging and removing any selected column in the group. For peripheral columns, not accommodatable in symmetrical groups of twelve, a uniform standpipe spacing is maintained. If the columns in a group are numbered 1 to 12 as in Fig. 2, satellite standpipes 25 are disposed as shown and contain shut-down rods 28. A trim rod 26 is associated with column 1 and secondary shutdown rods 27 with columns 5 and 9; rods 26, 27 are within standpipe 23. Refuelling-. Fig. 3 illustrates the method of refuelling applied to columns 1 to 4: a sleeve 29 with a fixed absorber at I and J is positioned before refuelling, the refuelling probe is centred on B and, after introduction through standpipe 23, is rotated to carry a cranked end to position C. A column is lifted clear and withdrawn along locus DC by inward movement of displaceable coupling means until at point C. The probe is then rotated through 180 degrees about its axis to locate the column at A and the probe is then raised. For removing blocks of column 4 the cranked end of the probe is rotated to C 1 . An alternative arrangement uses a radius of 2r. A refuelling tool may incorporate a grab Fig. 4 (not shown), or a pick-up inserted through the blocks, Figs. 5, 6 (neither shown). Refuelling can be rotated to suit irradiation and burn-up requirements in specific parts of the core.

Title: Improvements in gas burner fittings for domestic grates, boiler stoves and the like
IPC: G05D23/02
Filed: 1928-09-13
Abstract: 319,914. Keith & Blackman Co., Ltd., J., and Keith, G. Sept. 13, 1928. Thermally-actuated valves. -In a gas fitting for domestic grates and the like, burning coke or other solid fuel which is initially ignited by a gas burner, a thermostatically controlled gas valve is provided to ensure that the gas is cut off after the solid fuel is ignited. The gas valve plug 24, located between the inlet 30 and outlet 31, is of the screw-down self-closing type. The plug is rotated by a spindle 16 which has a collar 21 maintained in contact with a seating in the cover by a spring 22 to form a gas-tight joint. The spindle is rotated and the valve opened by hand against the action of a spring 32 until a screwhead 13 enters a slot 12 in a trigger plate 11, this being attached to a member 6 pivotally mounted on a pin 7 upstanding from the valve body casting. The trigger plate is retained in engagement by a flat strip spring 18. A thermostat of the rod and tube type, 1 and 2, located beneath the grate, has a finger 5 formed on the moving element, this finger bearing against the pivotally mounted member 6 and thus causing the trigger plate to disengage and so release the valve on reaching a predetermined temperature If it is desired to reset the valve in the open position whilst the trigger plate 11 is inoperative, a second catch member 33 is engaged by hand.

Abstract: 692,879. Free-wheel clutches; apicyclic gearing. S.S.S. GEARS, Ltd. Oct. 4, 1951 [Oct. 27, 1950], No. 26298/50. Class 80 (ii). A one way clutch, comprising an intermediate member 1 helically splined on a shaft 2, may be locked, for the transmission of torque in either direction, by plungers 13 which project through radial holes 12 in a sleeve 10 attached to the shaft 2. The plungers engage a circumferential groove 11 in the member 1 and are projected into the operative position by a sleeve 14. When a, circumferential groove 15 in the sleeve 14 is disposed opposite holes 12 the plungers 13 may be moved outwardly by the member 1 in moving to its disengaged position. In this position pawls 6 overrun teeth 4 on the coupling member 3. In a further embodiment, Fig. 2 (not shown), two locking plungers serve alternatively to prevent the intermediate member of an invertible free wheel coupling from moving out of the engaged position into one of its free-wheeling positions while allowing it to move into the other free-wheeling position. The plungers 13 may have rounded ends, be balls (if the sleeve 10 is thin enough), or have flat inner ends in which case they are disengaged by centrifugal force. Fig. 3 shows the coupling applied to an epicyclic gear in which teeth 53 on an intermediate member 51 are movable from engagement with teeth 46 on a planet carrier 42 (one to one drive) into engagement with stationary teeth 50 (reduced drive). Locking plungers 63, 64 engage alternately a groove 59 or shoulder on a reduced portion 60 of the member 51 to lock the gear in its reduced drive position or to prevent it from moving into the reduced drive position from the direct drive position. The member 51 is helically splined on the sun shaft 48 and in its intermediate position sets of pawls 54, 55 ratchet over the teeth 46, 50. Specifications 354,711, 410,083 and 486,589 are referred to.

Abstract: 406,773. Testing asphalt paving and similar materials. TAYLOR, N. H., 12, Bukit Tunggal Road, Singapore, Straits Settlements. Sept. 27, 1932, No. 26787. [Class 106 (ii).] A circular area in the centre of a supported. disc of the material at any predetermined temperature is submitted to a uniform rate of loading so that deformation of the cylinder of material below the circular area bursts the restraining annular ring of material not directly stressed, and the corresponding load is measured. A pump A2 worked by a handle B supplies pressure liquid to a jack Al the plunger A3 of which projects through the base of an oven and supports on the circular head A4 the specimen E1. Oil under pressure from the jack passes through a pipe A5 to act on a plunger C1 the thrust of which is communicated to a lever C2 having a fulcrum F. At one end the lever carries a container C3 and is balanced at the other end by a weight C4. In use, the specimen E1 which has been maintained at the required temperature for one hour prior to the test, is placed in the oven on the head A4. The plunger A3 is raised by pumping until the sphericalheaded distance piece E2 is in contact with an abutment E. The jet D1 is now opened and sand from the reservoir D2 admitted to the receptacle C3 the pump being operated at such a rate as to keep the lever C2 floating. A rod F1 raised by upward movement of the head rotates through rack and pinion gear the recording drum F2. A pen in contact with the drum is drawn longitudinally across the drum at a constant rate by clockwork F3, the speed being controlled by a governor F4 and is adjusted so that the position of the pen corresponds to the loads marked on the record card and to load on the test piece. Rupture is indicated by a rapid increase in deformation.
