Patent GB-1277383-A (GB)
Title: Nuclear refuelling arrangement
Inventor: MCCONKEY KENNETH NORMAN
IPC: G21C19/02
Filed: 1971-03-16
Abstract: 1277383 Fuel elements CANADIAN GENERAL ELECTRIC CO Ltd 16 March 1971 6994/71 Heading G6C A fuel bundle 12 is retained within a pressure tube 15 by means of a plurality of latch fingers 20, these being held radially inwardly by springs 22 mounted on pins 23. Each of the latch fingers 20 has a radially inwardly projecting nose portion 24 which engages with an axial end face or shoulder of the outer resident bundle 12 to retain the bundle within the pressure tube. The radial location of the bundle 12 within the tube 15 is determined in part by spacer pads 16 projecting from the outer fuel elements of the bundle. The annular recess formed between a fuel bundle 11, being entered during on-load refuelling by the ram 14 of a refuelling machine into the pressure tube 15, and the outer resident bundle 12 and into which the nose portion 24 of each latch finger 20 extends is provided with a clearance "C", by the relative axial dimensions of the end portions 18 of each of the bundles 11, 12 in relation to the axial extent of the nose portions 24 at a radius equal to the outer radius of the bundles. This clearance "C" permits the ram 14 to advance the bundle 11 axially towards the pressure tube, so as to relieve all the latch fingers 20 from the axial hydraulic load applied by the coolant acting upon the bundles within the pressure tube. This hydraulic load would otherwise produce large friction forces and undue unit loading on the last individual latch finger 20 maintaining contact with the outer resident bundle 12. Substantially simultaneous withdrawal of the fingers 20 occurs as the ingoing bundle 11 contacts the fingers, the bundle 11 then being fully inserted against the coolant flow for engagement in latched relation with the fingers 20.

Title: Carbonaceous products of very low permeability
IPC: C04B35/532
Filed: 1964-02-20
Abstract: Carbon articles of very low permeability to liquids and gases are made by giving a definite shape to a mixture of a carbonaceous body material and a carbonaceous binder, the body material consisting exclusively of divided graphite of which from 10 to 50% by weight is of previously graphitized carbon black having a particle size between 0.5m  and 0.005m  and the remainder is of graphite dust having a particle size between 400m  and 0.5m .  The shaping is preferably effected by extrusion.  The binder is preferably a thermosetting resin prepolymer, for example non-branched and medium-branched products resulting from partial preliminary condensation of an aldehyde, a phenol, an amine derivative or, preferably, an unsaturated cyclic alcohol such as furfuryl alcohol.  Preferably, from 180 to 230 parts by weight of the resin binder, which may have an acid catalyst added to it at the time of use, are used per 1,000 parts by weight of the body material when shaping is by extrusion. The articles preferably receive their dimensions and their final shape, for example round bars, plates, strips, tubes or T, L or I sections, through the extrusion process, which is preferably effected at a temperature of from 40 DEG  to 70 DEG  C.  The articles obtained may be fired and may be further heat-treated in a graphitization process. Examples describe the production of articles which are claimed to have an apparent density of from 1.85 to 1.96 g/cm.3; a permeability of less than 10-6 cm.2/sec. for raw or baked articles, of 10-5 cm.2/sec. for fired articles, and of 10-4 cm.2/sec. for graphitized articles; a porosity not exceeding 6% under a pressure of 1,000 kg/cm.2 mercury for graphitized articles; and pore dimensions between 0.1m  and 0.5m  for graphitized articles.

Title: Improvements in adjustable aerials
IPC: H01Q9/14
Filed: 1943-05-08
Abstract: 565,526. Aerials. STANDARD TELEPHONES & CABLES, Ltd., and WILLOUGHBY, E. O. May 8, '1943, No. 7329. [Class 40 (v)] An adjustable aerial for tanks, motor vehicles, &c. comprises a flexible conductor 3, Fig. 1, secured at one end to a flexible cord 4 passing over a support 6, the free ends of the conductor and cord being wrapped round drums 1, 2 in such a way that as one is wound up the other is unwound. The drum 1 is connected by wiper 8 to the transmission line 9. The conductor and cord are housed in a tubular flexible casing of non-conducting material. A "non- corona " termination, e.g. a metallic sphere 5, is provided at the upper end of the conductor. In order to increase the ratio of the electrical length to the physical length as the conductor is unwound, capacity loading is automatically brought into effect. This may' comprise a conducting cap or tube 17, Fig. 4, over the end of the flexible casing 7 and a cylindrical conducting member 3<1> (of length just less than one quarter of the shortest wave-length required) secured between the conductor 3 and cord 4 so as to form a capacity with the tube 17 which is varied as the aerial is adjusted.. Additional capacity loading is provided by a metal sphere or a number of rods 16 capacitycoupled to the tube 17. Shunt capacity to earth of the winding-drum is compensated for at the-high-frequency end of the wave-band by a series inductance between the aerial and the transmission line, Fig. 3 (not shown).

Title: Improvements in wagon tipping apparatus
IPC: B65G67/00
Filed: 1935-03-08
Abstract: 453,487. Wagon - tipping apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and ROBSON, R., c /o Fraser & Chalmers Engineering Works, Erith, Kent. March 8, 1935, No. 7337. [Class 78 (iv)] [See also Group XVIII] Wagon-tipping apparatus associated with weighing-apparatus is arranged so that the wagon is supported by the weighing-apparatus only during part of the tipping movement and not in the fully-tipped or initial untipped positions, while the act of tipping imposes no vertical thrust on the weighing-apparatus. The wagon is run on to a platform 2 which is rigidly connected to the axle 4. The latter carries segmental rope pulleys 3 at its ends connected to the tipping drums 6 by ropes which are led off horizontally to pass over pulleys 7 so that by winding up these ropes the platform and truck are rotated about the axle 4 to tip the contents into the hopper 9 without applying any load to the weighing- apparatus. Mechanism as described in Specification 438,157 engages the chains 11 and holds the wagon on the platform during this process. The weighing-apparatus comprises two beams 12, resting on knife-edges 14 and engaged for weighing with members 15 at the ends of the axle 4. Normally, flattened discs 17 on the axle engage fixed surfaces 19 and prevent engagement between the members 15 and the beams 12, but the initial tipping brings the flattened portions 18 opposite to the surfaces 19 and lowers the members 15 on to the beams 12. The latter then operate an indicator through linkage 13. The continued act of tipping re-engages the members 18, 19 so that the weighing-apparatus is not functioning during the actual transfer of the load. On the return journey the weighing- apparatus will be momentarily re-engaged to register the tare of the empty truck and platform. The members 15 are carried by levers pivoted to the hopper. In the modified form shown in Fig. 3, the axle 4 is connected to driving ropes 26 so that it rolls along its bed in the process of tipping. At one point it rolls over the member 24 and depresses it to actuate the weighing-apparatus.

Title: Firing circuits for pulse-fed dc electric motors
IPC: H02P7/29
Filed: 1975-03-03
Abstract: 1495981 Control of D.C. motors LANSING BAGNALL Ltd 3 March 1975 [19 Feb 1974] 7383/74 Heading H2J A control circuit for a D.C. motor comprises a current path including a winding of the motor, a current chopper and a current senser; a voltage divider for receiving operating pulses and consisting of a saturable inductive impedance element and a capacitive element; means for producing magnetic flux in the impedance element in accordance with the current flowing in the current path and sensed by the senser; an electric switch connected by way of a passive integrator to the impedance element for operation when the voltage across said element and integrated by the passive integrator exceeds a predetermined threshold; and means responsive to the operation of the switch to render the chopper conductive. The invention may be applied to control the field winding of a separately-excited or shunt motor or, as shown, the armature winding 2 of a series motor in circuit with a thyristor 3, which is fired to connect the winding 2 to a D.C. supply and turned off by a commutating circuit generally similar to that described in Specification 1,136,253. Also as in the latter Specification, the motor current is sensed by the coil 1 of a saturable reactor 7 whose second winding forms, with a capacitor 6, a series-resonant voltage divider receiving firing pulses at terminal 5, which pulses switch on a transistor 10 to fire thyristor 3 through circuit 11 when the motor current is below a predetermined value producing saturation of the reactor 7, firing thus being prevented at currents above this value. Members 8, 9 constitute the passive integrator responsive to the voltage across the reactor 7 to generate a voltage across capacitor 9 sufficient to switch on transistor 10 only during the first half-cycle of the voltage across capacitor 9 and thus the first quarter cycle of the voltage across the reactor 7. Hence the rectangular pulses applied at terminal 5 will produce across capacitor 9 a voltage sufficient to switch on transistor 10 (provided reactor 7 is unsaturated), but transient signals will not produce a sufficient voltage and hence undesired firing of the thyristor 3 will be prevented.

Abstract: 693,910. Water-tube steam boilers, superheaters. FOSTER, WHEELER, Ltd. March 28, 1951 [March 28, 1950], No. 7756/50. Class 123 (ii) and 123 (iii) In a steam boiler comprising a furnace 18 from which combustion gases flow through a bank 14 of steam-generating tubes, extending from an upper steam drum 10, to a lower water drum 12, to an exhaust duct 22, the latter locates final and initial steam superheaters 34, 26 respectively followed by an economizer 52 and air preheater 54; a desuperheater 30 is also fitted in the air supply duct 44 between the preheater 54 and the furnace burners 20. The flow of gases through the superheaters is controlled by dampers 40, 42, and the flows of combustion air through the preheater 54 and an associated by-pass by dampers 56, 58 respectively, these dampers being controlled by pistons 64, 65 actuated by a change-over valve 62. With the dampers in the positions shown a high degree of superheat is possible; when low superheat is required the dampers are set in the opposite positions so that the superheater 34 is by-passed by the gases and the preheater 54 by air, relatively cool air thus flowing to the desuperheater 50. Instead of, or in addition to, causing the air to by-pass the preheater, the combustion gases may be caused to by-pass said preheater by operation of a damper 60. The final high or low steam temperature is maintained constant by one of two thermostats 66, 67 which are fitted in the main steam outlet pipe 36 and are brought selectively into action upon operation of a valve 63, said thermostats controlling, through a regulator 69 and piston 73, dampers 46, 48 in the duct 44 associated respectively with the desuperheater 30 and a desuperheater by-pass.
