    • 912,659. Servicing reactors. ATOMIC POWER CONSTRUCTIONS Ltd., ASHLEY, J. W., HODSON, P. D., ROGERS, F. J., and NICHOLS, M. W. April 17, 1959 [April 17, 1958], No. 12277/58. Class 39 (4). The lower ends of fuel element channels 5 (only one shown) in the reactor core 4 have extensions 17 leading to one of a number of selectors 16, each selector serving a group of channels, e.g. 315 channels, the lower ends 19 of the extensions 17 of a group being arranged on nine concentric circles each circle having thirty-five ends 19. A rotatable plug 20 in the selector has nine passages 21, the passage entries 22 lying on a common radius but the passage ends 23 each lying on a different radius corresponding to the radii of the circles on which the ends 19 are located. A lower rotatable plug 24 has a single passage 25 having a central entry 26 and an exit 27 lying on a circle having the same radius as that of the entries 22. The channel 5 to be loaded or unloaded is selected by rotation of the plugs 20, 24 and a flexible probe 14 is brought out from a dispenser 15 to support the lower end of the fuel elements 28. A charge machine 9 movable over the shield 3 is aligned with a selected hole 8 and standpipe 10 (only one hole and one standpipe being shown) and a pantograph 13 is lowered from the machine and extended to be in alignment with the channel 5 from which the fuel elements are to be discharged. The probe 14 then lifts the fuel elements 28 in the selected channel so that the upper fuel element is received in the pantograph 13, the latter being retracted so that the element may be lifted by a hoist into the machine 9. In a charging operation the process is reversed, the fuel elements being lowered singly into the pantograph which is then extended and the fuel element lowered into the channel by withdrawing the probe 14.

    • 447,854. Actuation of switches. DEAN, G. P., 14, Baldwins Gardens, Holborn, London, and CALDWELL, T. F., 46, Clare Road, Hounslow, Middlesex. May 1, 1935, No. 13042. [Class 38 (v)] A time-switch device for interrupting an electric circuit after a predetermined time, particularly for use in timing X-ray photographic exposures, comprises electromagnetic coupling means having a part continuously rotated at a constant speed, and another part which, when the electromagnet is energized, turns with the first part and by contact with an adjustable stop co-operating with relatively movable contacts, causes the interruption of the circuit after a predetermined time. In the arrangement shown, a synchronous motor 5 drives, through reduction gearing, a shaft 10 carrying an insulating bush 16 on which are mounted slip rings 17, 18 and the soft iron casing 20 of the coil 21 of an electromagnet, the ends of the coil being connected to the slip rings. The armature 24 of the electromagnet is normally prevented from rotating with the magnet by a spring 25, but when the magnet is energized, the armature is attracted and rotated against the action of the spring until an extension 59 of the armature engages an abutment 60 carried by a pivoted arm 61 and moves the latter to separate contacts 66, 68. The contacts are connected to slip rings 30, 31, and the arm 61 is carried by an arm 64 connected to the slip rings, the arm 64 and slip rings being connected to an operating knob 39 by means of which they can be adjusted about a fixed shaft 32. The slip rings are engaged by brushes 33, 34 connected to terminals 37, 38. The knob 39 carries a pointer 40 which co-operates with a ring of graduations outside the front plate of the apparatus, and a ring 41 with recesses 43 corresponding to the graduations is mounted on the inside of the plate. An arm 45 connected to the knob is formed with a projection 46 adapted to engage one of the recesses 43 when the knob is turned to set the apparatus for a required time interval. A fine adjustment is obtained by a second knob 51 geared to an arm 47 loosely mounted on the shaft 32, said arm carrying an arcuate strip 47A formed at its end with an abutment 47D and a short inclined plane 47B engaging an extension 47c of the arm 45. Each division on the ring 41 corresponds to a tenth of a second, while the knob 51 enables adjustments to a hundredth of a second to be obtained. The circuit connections are shown in Fig. 4. The motor 5 runs continuously as long as a main switch 81 is closed. On closing a push button switch 82 the electromagnet is energized from the secondary winding 87 of a transformer, and the armature 24 rotates until its extension 59 engages the abutment 60 and separates the contacts 66, 68. The winding 85 of a contactor 86 is energized as soon as the push button is depressed and remains energized until its circuit is opened at the contacts 66, 68. The contactor controls the circuit of the primary of the X-ray transformer, which is therefore energized for the time taken by the extension 59 to reach the abutment 60, which is determined by the setting given to the knobs 39, 51. As soon as the push button is released, the electromagnet is de-energized and the armature returns to its initial position.

S., 4, Queen's Court, Queen's Road, Bayswater, London. July 4, 1931, No. 19348. [Class 40 (v).] The reception of a signal by a detector valve energizes an electromagnet which closes the circuit of a buzzer or other calling device, whereupon the operator switches in manually a low-frequency amplifier and a 'telephone receiver. As shown in Fig. 1, a loop aerial L1 .is associated with a back-coupled detector valve V1, which includes quenching circuits L4 C4, L5 C5 in its grid and plate circuits so that it operates on the super-regenerative principle. The detector plate circuit also includes a transformer coupling to an audiofrequency amplifier V2 and the contacts 1, 2 of a plug A. The contact 3 on the plug completes the filament circuit of the valve V1. Contacts 1, 2, 3 are wired to contacts 1 , 21, 31 of a buzzer, Fig. 2. On receipt of a signal, the current in a coil C changes and contacts E close, making a circuit from the HT positive through contact 2 , buzzer contact and coil D, and contact 3 to HT negative. On hearing the call, the operator plugs in his telephone plug B, so closing the filament circuit of the valve V2. The buzzer may be put out of action by a separate hand switch, or by contacts operated by the plug B, or by withdrawing the plug A. In the latter case, the plug is arranged to maintain the detector filament and plate circuits energized. If the valve V2 should fail, the plug B may be inserted in place of the plug A.

    • 369,983. Valve amplifying circuits. DEAN, C. L. P., 73, Drayton Gardens, West Drayton, Middlesex, and BEGBIE, C. W. H., 5, Easter Terrace, Brighton. Nov. 1, 1930, No. 32944. [Class 40 (v).] In a super-regenerative wireless receiving circuit of the type described in Specification 182,135, [Class 40 (v), Wireless signalling &c.], variable or fixed resistances are inserted in series with and on the high frequency side of the quenching unit in the input and/or the plate circuit of the valve, in order to stabilize the circuit. By this means a receiver embodying the circuit can be made small enough to be carried in the pocket. The Figure shows the usual Armstrong circuit with resistances 16, 14 in series with the quenching units 10, 11 ; 12, 13, which may be constructed as plug-in units. The circuit may be adapted for use with a pentode valve as in the drawing accompanying the Provisional Specification (not shown). Suitable values of inductance, resistance and capacity for the various components are given.
