Apparatus for transferring new and spent fuel elements between a chamber within a reactor containment and the exterior of the containment is described with reference to a reactor fuelling facility disclosed in Specification 1,002,006, in which a chamber 8 within a containment 9 contains a rotary beam 6 having three superimposed sets of rails 12, 14, 16. The upper rail 12 supports a carriage carrying a grab (Fig. 2, not shown) whereby fuel elements may be loaded into or removed from fuel element channels in the reactor core, this grab passing through apertures in a slab 10 separating the core from the chamber 8. The grab deposits the spent fuel elements removed from the core in magazines 28 having six compartments 32. The magazines 28 run on the lower rail 16 and are moved by a carriage 26 running on the middle rail 14 and may be left for a period to cool off in storage positions around the periphery of the chamber 8 as disclosed in the aforementioned Specification. The apparatus of the present invention includes a tunnel 41 leading to the chamber 8 and having a rail 40 whereby when the rail 16 on the beam 6 is aligned with the rail 40 the carriage 26 may transfer a magazine 28 to the rail 40 and a trolley 42 on the rail 40 may move the magazine beneath a series of six ducts 58a corresponding to the magazine compartments 32. The ducts 58a serve as inlet ducts to a lock chamber 62, Fig. 4, a similar number of outlet ducts 58b being provided. Valves 74a, 74b in the ducts 58a, 58b enable the chamber 62 to be at reactor pressure or at atmospheric pressure. The chamber 62 is largely filled with concrete 80, Fig. 5, and contains a band conveyer 64 having a series of compartments 65 for receiving fuel elements, movement of conveyer enabling the various compartments to be aligned with the ducts 58a, 58b. Thus by operating push-rods 60a fuel elements may be transferred between a magazine 28 and the conveyer 64. The lower ends of the ducts 58b extend to a rail supporting a trolley 82 carrying a magazine 84 having seven transverse rows each of six fuel element receiving tubes whereby by operating push-rods 60b and moving the trolley fuel elements may be transferred between successive rows and the compartments 65 of the conveyer 64, the latter also being moved in steps of six compartments corresponding to each row. An elevator shaft D houses a vertically movable skip (Fig. 6, not shown) whereby when the trolley 82 is moved into the shaft the skip may remove the magazine 84 from the trolley and transfer the magazine to the exterior.

Abstract: 1,154,606. Bipolar signal detector. INTERNATIONAL STANDARD ELECTRIC CORP. 25 Oct., 1967 [3 Nov., 1966], No. 48477/67. Headings H3T and H4L. In a circuit for detecting bipolar signals (i.e. signals in which "zero" is a zero voltage and "one" is alternately positive and negative), the input signals are applied to a threshold detector producing monopolar signals and having its threshold obtained by comparing a variable voltage with the peak or average of the output voltage and applied through a differential amplifier preceding the detector. In the circuit shown, bipolar signals are passed through an equalizer EQ and a linear amplifier Q 1 , Q 2  to a threshold detector Q 3 , Q 4 . This produces a monopolar output which follows the input when it exceeds a threshold dependent upon its emitter voltage U 2  and the mean value of the voltage of the collectors of Q 1  and Q 2 . The peak output is detected by ACl and if the switch is in position 1 this output is compared with an adjustable reference U 3  and controls the mean current in Q 1  and Q 2  and thus the threshold. The output of the threshold detector is squared by Q, and if the signal is such that "zeros" and "ones" occur with equal frequency, as in pulse code modulated speech, the average value may be determined by AC2 and used to control the threshold.
