Filed: 1973-02-09
Abstract: 1424037 Transformers; TAIYO YUDEN K K 9 Feb 1973 [17 Feb 1972] 6575/73 Heading H1T [Also in Division H4] A compensation arrangement for pincushion distortion in TV receivers, comprises an open magnetic circuit provided by ferrite core 2 having flange portion 6 between two further portions, permanently magnetic biassing means (e.g. plate magnets 12, 13) providing a bias flux through the core portions, two sets of primary and secondary windings with their secondary windings 10, 11 connectable in series opposition, and magnetic adjusting meanscomprising at least one piece of permanently magnetic material disposable in alternative locations provided by a non magnetic member in the flux path to provide alternative flux conditions in the further portions, the or each piece of magnetic material providing a component of magnetic flux which is small compared to the biassing flux. Vertical and horizontal deflection currents flow through windings 8, 9 and 10, 11 respectively and the reactor is encased in non- magnetic material with a synthetic resin member. Holes 14 to 18 receive small magnets for bias field compensation. Hole 15 for example may receive a flat truncated wedge-shaped magnet with one pole at each of its two largest wedge faces (Fig. 4A, not shown). Hole 10 may receive a similar magnet with one pole at each of its larger non-parallel side faces, or both magnets may be in combination in a small hole. The magnets may be of other shapes (e.g. cubes). Fig. 5A (not shown) indicates strengthening of bias field between flanges 5 and 6, and weakening between flanges 6 and 7, while in Fig. 5B (not shown), magnet in hole 14 produces weakening between flanges 5 and 6 only, or on reversal, strengthens this bias. Hence, the overall pincushion distortion may be adjusted as well as differences in pin-cushion distortion between the top and bottom of a reactor.

Abstract: 959,852. Fuelling reactors. NUCLEAR POWER PLANT CO. Ltd., and A. E. I. -JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. Jan. 23,1963 [Feb. 20, 1962], No. 6582/62. Heading G6C. A jig for loading a number of fuel elements placed end-to-end into a fuel channel of a reactor so that tensile loads are not transmitted between individual elements of the assembly comprises at its upper end a tube 2 having a lifting head 7 for engagement by a grab and slidably receiving a weight 3. A rod-like extension of the lower end of the weight contacts the upper end 4 of the fuel element assembly, the lowermost fuel element 8 of the assembly contacting the part 10 of a jig release unit 9. The several contacting surfaces between the individual fuel elements of the assembly and between the ends of the assembly and the jig may comprise interfitting conical projections and recesses. Tie rods 6 extending from guide vanes 5a in the tube 2 have bifurcated lower ends 6a bridged at their extremities by pins 18, these pins engaging pawls 15 forming part of the release unit 9. The unit 9 comprises a tubular member 11 connected to the part 10 and receiving a plunger 12 biased by a spring 13, a sleeve 14 slidable over the lower end of the member 11 having flanges 14a to which the pawls 15 are pivoted by pins 16. Aligned slots 11a, 14b in the member 11 and sleeve 14 permit the pawls to extend therethrough and engage the plunger 12. The member 11 has flanges 11b aligned with the flanges 14a and these flanges 11b, 14a have opposed recesses 19 receiving a compression spring 20 whereby when a fuel element assembly is lowered into a reactor the. load is transmitted from the member 11 to the tie rods 6 by the spring 20 and pawls 15 as in Fig. 2. When the plunger 12 engages a fuel element support in the reactor channel it moves upwards relatively to the member 11 and compresses the spring 13 and gradually takes over the load of the fuel element assembly whereby the spring 20 is able to move the sleeve 14 downwards on the members 11 and the pawls 15 rotate inwards, Fig. 4, thereby releasing the pins 18. The parts 2, 6, 7 may now be withdrawn. To prevent unwanted release of the pins 18 in the event of the plunger 12 meeting an obstruction, a shroud 21 is fixed to the member 11, The shroud engages the obstruction but is shaped to co-operate with the fuel support in the reactor channel. If the jig is used to load a horizontal channel the weight 3 is spring biased.
