Title: Improvements in or relating to nuclear reactor systems
IPC: G21C7/04
Filed: 1965-09-10
Abstract: 1,078,318. Reactors. GENERAL DYNAMICS CORPORATION. Sept. 10, 1965 [Sept. 14, 1964], No. 38704/65. Heading G6C. An inherently safe power reactor having inherent load-following capability comprises a pressure vessel 17, thermal shield 33, reflector 25 and a core 21 containing elongate fuel elements 23. The fuel elements are arranged to form an annulus with a central region 29 extending therethrough which does not contain fuel. The fuel elements 23 described in detail with reference to Figs. 5-8 (not shown), have a negative temperature coefficient of reactivity and contain a homogeneous fuelmoderator mixture of zirconium hydride and highly enriched uranium together with a burnable poison, e.g. erbium 167 or lutecium 176. The central region 29 accommodates a honeycomb structure 121 (Fig. 9, not shown), through which the coolant may flow. Water, serving as both coolant and moderator, enters the pressure vessel 17 through an inlet 193 under pressure from a pump 201 (Fig. 4, not shown), passes down over the reflector 25, enters apertures in the bottom grid plate 83 and rises through the annular array of fuel elements 23. During its upward movement at about the level B-B the water becomes a mixture of steam and water. The boiling water passes through apertures in the top grid plate 115, enters a chamber 37 and then passes down through the fuel-free region 29 constituted by the structure 121. At the bottom of the region 29 the boiling water passes through an opening 69 and then flows upwards in the annular passage 35 to the outlet 197. From the outlet 197 the steam water mixture passes to a liquid vapour separator 45 and the steam passes to a turbine 199 through a throttle 203 actuated by a controller 205 (Fig. 4, not shown). The inherent loadfollowing capability of the reactor results from the fluid coolant-moderator in the annular core region constituted by the fuel elements having a positive density coefficient of reactivity and the fluid coolant-moderator in the central fuel-free region 29 having a negative density coefficient of reactivity. The design is such that when the load is changed (i.e. by the throttle 203) the net reactivity increment produced by changes in fluid density in the annular and fuel-free regions of the core balances the reactivity increment resulting from the concurrent change in temperature of the fuelmoderator mixture.

Radiation from a source 1 is reflected by the mirror 7 on to two photo-resistors 2, 3 positioned above a L.E.D. source 1, as shown. The amount of light received by each detector is dependent upon the deviation (if any) and its direction. The detectors' outputs are used to control a servosystem which moves a carriage assembly 6g that supports the arrangement. A mask, Fig. 4, may be positioned in front of the source 1 and detectors 2, 3 (also Fig. 3 not shown). As can be seen in Fig. 4, the top two sections 42, 41 of the mask that are positioned in front of the photo-detectors and are out of phase by half a period in opposite directions with respect to the bottom portion 43, which is positioned in front of the source. The overall effect is to increase the sensitivity and the linearity of the system.

Title: Improvements in or relating to circuit arrangements for reducing crosstalk in automatic telephone exchanges
IPC: H04Q3/52
Filed: 1957-12-17
Abstract: 829,514. Reducing crosstalk in automatic exchanges. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 17, 1957 [Dec. 20, 1956], No. 39203/57. Class 40 (4). In an automatic telephone exchange of the type in which connections are established by single switched wires, the return currents flowing through non-switched wires which are grounded, crosstalk is reduced by providing an individual return wire for each such single wire, the return wires being commoned to ground at the beginning and end of the single wires, and by including in each single wire one winding of an individual transformer having a one-to-one turns ratio, the other winding of which is included in the individual return wire of that single wire. In the arrangement shown, the two primary switches P1, P2 and the two secondary switches P3, P4 are of the cross-bar type having speech contacts such as G11 which may be mechanical contacts or may consist of rectifiers, gas-discharge paths, or transistors. The vertical conductors V1, V2 are each connected through a winding on transformers T1, T2, respectively, to the multiple point M1 (common to switch P1), and are also coupled by these transformers to subscriber's lines AB1, AB2 respectively. The single wires S13, S14, S23, S24 are associated with return wires H13, H14, H23, H24, respectively, each of which is preferably twisted with its associated single wire. The single wires each include the primary winding of the respective transformer of T13, T14, T23, T24, the secondary windings of which, each having a number of turns equal to the primary, are connected in series with the respective return wires. The windings are connected so that currents flowing in opposite directions in a single wire and the associated return wire counteract each other magnetically, so that for these currents the impedance is small, whereas for unidirectional currents the impedance is high. The multiple points M1, M2, M3, M4 are connected together and to ground. Operation.-Assuming the subscriber AB1 to be extended to output U11 via G13, S13 and G11, the return current will substantially all flow via H13, rather than through all the return wires as it would in the absence of transformer T13. Return currents flowing in H13 due to other conversations may give rise to a small crosstalk voltage between M1 and M3, but transformer T13 causes an equal but out-ofphase voltage to be induced in S13. Any crosstalk voltage induced into S13 from other single wires produces, due to the twisting of S13 with H13, equal and equally-directed voltages in H13, which two voltages would, in the absence of T13, produce unidirectional currents in H13 and S13 in parallel in a circuit completed over the other return conductors. Transformer T13, however, offers high impedance to these currents and largely prevents their occurrence.
