Title: Improvements in or relating to nuclear reactors
Inventor: BATTLE NORMAN
IPC: G21C15/20
Filed: 1961-05-16
Abstract: 939,982. Nuclear reactors. ROLLS-ROYCE Ltd. July 26, 1962 [May 16, 1961], No. 17882/61. Class 39 (4). - A nuclear reactor has a calandria tank for moderator liquid (for example, heavy water); fuel channels which contain fuel elements and through which coolant flows, said fuel channels comprising calandria tubes having coaxially arranged within them coolant/fuel element tubes; and shielding to surround the calandria tank, which tank is supported within the shielding by being suspended from a top shielding structure by the said fuel channels. In one arrangement, Fig. 1, the calandria tubes 20 terminate at the wall 13b of the tank 13 and are sealed thereto and to the inner tubes 35 which then extend through the shielding structure 14 and are secured by individual collars 35a. Tubes 35 pass freely through the bottom shield structure 15. Tank 13 is surrounded by an annular reflector tank 16a, 16b on which rests the shielding structure 14, and which rests on bottom shielding 15 supported in the main shielding 10. Tank 13 also contains tubes 21 which are the control tubes, the reactivity being varied by changing the level of the moderator or absorber liquid in these tubes. Moderator circulates through the remainder of the tank 13. The shielding structures 14 and 15 are separate from the main shielding 10 and the thermal shields 12a, 12b, 12c, and are assembled as a unit with the calandria tank and are inserted as such into the main shielding. The steam coolant passes from ring main 41 down through tubes 35 and passes via tubes 43 into main 44. An alternative method of suspending the calandria tank is shown in Fig. 4. The top shield structure comprises a top plate 50 and a series of metal bobbins 51 having their bores 51a aligned with the fuel channels and with the holes 50a in the plates. The fuel channels are doublewalled as previously described but in this case both the inner tube 35 and the calandria tube 20 extend through the holes 50a and project beyond the surface of plate 50. An end portion of tube 20 is externally threaded and is encircled by a shim 53 and by collar 54 which has a projecting flange 54a which seats on the end of tube 20. The thickness of shims 53 is individually selected so that the load of the calandria tank is evenly distributed among the fuel channels. Connector piece 62 has side arm 62a for admission of coolant steam, and an extension 62c serves as a support for the fuel element hanger 65. The Provisional Specification describes a modified connection between the tubes 35 and the top plate 50. Specification 927,071 is referred to.

Title: Rolling shutter with device enabling it to be extended towards the outside
IPC: E06B9/92
Filed: 1946-06-14
Abstract: 613,554. Window shutters. KIEFER, H. June 14, 1946, No. 18012. [Class 20(iii)] A roller shutter 3 is guided at each side by two guide members, one sliding in the other, the upper end of one guide 4 being pivoted on a statiorary pivot 5 and the lower end of the other guide 6 being pivoted at 8 to an arm 7 the other end of which is pivoted on a stationary pivot 9, the positions of the pivots and the length of the arm being such that when the shutter descends completely its lower end is necessarily in its closed position. The Figure shows the shutter raised and the lower guide telescoped within the upper guide where it is held by its lower end engaging a spring-biassed pawl 36 on the arm 7. Descent of the shutter forces the pawl and the shutter becomes locked, by a bolt 16, cam 18, 41 and slot 40, 16, the lower guide which is thus caused to slide out of the upper guide, the arm rotating counterclockwise about the pivot 9 through a horizontal position to one in which it projects downwardly at an angle from the pivot and wherein the inner guide is engaged between a buffer 60 and a latch on the window sill. When the inner guide is wholly raised the guides are held against inward movement by a cam arrangement whilst the pawl 36 prevents outward movement.

Title: Improvements in or relating to electric inverter circuits
Inventor: JACKETS ALBERT EDMUND
IPC: H02M7/515
Filed: 1960-05-23
Abstract: 915,979. Inverting. GENERAL ELECTRIC CO. Ltd. May 18, 1961 [May 23, 1960; Jan. 6, 1961], Nos. 18107/60 and 653/61. Class 38 (2). An inverter circuit giving a substantially sinusoidal output includes an inductive element 7 which with the capacitor 11 forms a parallel tuned circuit, a smoothing choke 9 and a pair of semi-conductor controlled rectifiers 4,5 triggered alternately by pulses from a D.C. operated blocking oscillator at intervals less than the half-periods of the resonant frequency of the tuned circuit. In the arrangement shown, the inductive element 7 is an autotransformer having primary tappings B, D, a centre tap C and output tappings A, E supplying the load 12. The D.C. voltage 3 stabilized across the capacitor 24 by the Zener diodes 25, 26 supplies the self-excited oscillator comprising transistor 13, transformer 15, capacitor 18 and resistors 19 and 20. The pulse frequency, adjustable by the resistor 20, is arranged to be just less than one-half of the natural frequency of the tuned circuit. The semi-conductor rectifiers 4, 5 are arranged to have slightly differing characteristics such that when the switch 10 is closed one or other of them strikes first. Assuming rectifier 5 strikes, the terminal D is short-circuited to the supply terminal 2 and due to the tuned circuit the voltage across the rectifier 4 varies sinusoidally. When the pulse amplitude is sufficient to fire both rectifiers simultaneously the rectifier 5 which was conducting is immediately rendered quiescent by the sinusoidal variations across the winding BD, the rectifiers then conducting cyclically (Figs. 2 and 3, not shown). The capacitor 30 reduces variations in the tuned circuit frequency caused by the load 12. In an alternative arrangement (not shown) the choke 9 is connected in the negative supply line between the resistor 16 and the transformer winding 21.
