Abstract: 426,396. Valve generating circuits. RYALL, L. E., 52, Crescent Gardens, Eastcote, Middlesex. Aug. 28, 1933, No. 23820. [Class 40 (v)] The output of a back-coupled oscillator 12 is rendered independent of load conditions and variations in supply voltage by employing a voltage limiting device 3, of the type which limits equally both half-waves of the oscillation, connected across the transformer 4, from the output side of which the feed-back and output voltages are derived. The limiter may be a gas discharge tube or a combination of dry contact rectifiers, the resistance 15 being provided if the limiter has a negative impedance on flashing over. The arrangement of Fig. 3 is suitable for reintroducing the carrier in carrier suppression systems, the signal to be demodulated being injected at 19, 20, two discharge tubes 23, 24 being series-connected across the transformer 4. The feed back circuit is the same as in Fig. 1, and the arrangement is thus a demodulator system.

Title: Improvements in nuclear reactors
Inventor: DELL JOHN DAVID
IPC: G21C5/08
Filed: 1959-07-13
Abstract: 890,523. Nuclear reactors. BABCOCK & WILCOX Ltd. July 13, 1960 [July 13, 1959], No. 23953/59. Class 39(4) In a nuclear reactor having a restraint garter surrounding a stack of material providing the moderator of the reactor core, the garter includes fluid pressure responsive biasing means adapted when subjected to the pressure of fluid under super-atmospheric pressure supplied as coolant to the core to exert a force acting through the garter on the stack to restrain the material of the stack. Fig. 3 shows a plan view of part of the restraint means which include a number of channel-shaped stays 6 mounted in a groove in the moderator block 1, each stay 6 being provided with a central vertical rib 9 located in a recess in the groove. Adjacent stays 6 are coupled together by a pair of balance beams, of which the upper one 13 is shown, pivoted to the upper and lower plates of the stays 6 by pivot pins 15 passing through elongated holes in the balance beams. A pivot pin 21 passing through the balance beams carries a mild steel link 24 which extends to a pivot pin 22 which passes through elongated holes in the balance beams to allow the inner end of link 24 to rock a few degrees about pin 21. Pivoted to pin 22 are the ends of two link plates 26 (of which only the upper one is shown) connected by a pintle 29 to a lug 31 of a stainless steel bellows unit 32 filled with helium at a pressure of about ¢ 1b. per square inch absolute. The other end of the bellows unit is provided with a threaded stud screwed into one end of a mild steel tube 30 which extends centrally through the channel in stay 6 and forms part of a ring of linkwork encircling the core. The other end of each tube 30 is screwed to a threaded shank attached to a clevis pivoted to a pin 22, the two screw threads being of opposite sense to enable the initial tension of the linkwork to be adjusted by rotating the tubes 30. In operation the pressure within the reactor increases the differential pressure on bellows 32 and thus increases the tension in the garter to offset the effect of the pressure of the coolant gas in the cooling channels. In another arrangement. Fig. 6 (not shown), the tie rods 30 extend between pins 22 and the bellows replace the link 24. Specification 890,520 is referred to.

Title: Improvements in or relating to apparatus for indicating and/or controlling and/or recording the operation of hydraulic riveting and like machines
IPC: B21J15/20
Filed: 1931-08-28
Abstract: 391,842. Hydraulic presses. PATTISON, E. W., 51, Deansgate Arcade, Manchester.-(Schõffer & Budenberg Ges. ; Buckau, Magdeburg, Germany.) Aug. 28, 1931, No. 24194. [Classes 69 (ii) and 135.] Apparatus for use with a hydraulic riveting or other machine to ensure that the machine shall be manually or automatically controlled so that a predetermined pressure is applied for a predetermined time, comprises a Bourdon pressure gauge which acts electrically to operate a signal and/or shut off the inlet of pressure liquid to the machine when the predetermined pressure is attained, and a time signal and/or pressure releasing device operated when the pressure has been maintained for the predetermined time ; a record of pressure and time is also obtained. Adjustable pointers 32, 48, Fig. 1, are set to indicate the predetermined pressure and the predetermined time (in seconds), as switch 38, Fig. 4, is closed, and pressure is admitted. When the pressure gauge pointer 24 reaches the pointer 32, a circuit is completed through a signal lamp 11 and an electromagnet 10. The energization of the electromagnet releases the balance wheel 43, Fig. 3, of a clock movement, to set a shaft 42 and seconds pointer 39 into motion, and simultaneously engages clutch members 44, 45 to cause the motion of a strip on which the pressure is recorded by a pen. When the pointer 39 reaches the pointer 48, the circuit of the signal lamp 12 is completed. The lamps 11, 12 may be replaced or supplemented by devices which respectively shut off and release the pressure. When the pressure is released, the pointer returns to zero, and the circuit through the magnet 10 and lamp 11 is broken, the balance wheel being then stopped by a pawl 61 and the clutch members 44, 45 disen. gaged. A spring 63 then returns the pointer 39 and thus breaks the circuit of the lamp 12. Should the pressure not be cut off at the predetermined time, the continued rotation of pointer 39 acts on a circuit-breaker 57 against the action of a spring to open the circuit of the magnet 10 ; when the pointer 39 returns to zero, the circuit-breaker 57 again closes the circuit of the magnet 10, following which the pointer 39 again closes the circuit of the lamp 12, so that the latter is repeatedly lighted and extinguished. The apparatus has an electrical winding device 64 operated when the switch 38 is closed.
