Patent GB-432927-A (GB)
Title: Improvements in regulating devices for electrical apparatus
IPC: H02P9/18
Filed: 1934-05-24
Abstract: 432,927. Automatic regulation. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CHUBB, A. A., c /o General Electric Co., Stoke, Coventry. May 24, 1934, No. 15503. [Class 38 (iv)] The voltage of a generator G is regulated by the adjustment of tapped resistances RA and RB in series with the field winding M, the resistance gradations of RA being large and those of RB small. If the voltage is low the contact voltmeter V completes the circuit of a relay L which, by closing a switch C, initiates the operation of a chain of relays A, B, C, the operation of the final relay C energizing a relay SD which impulses the switch S1 round one step to remove resistance from the field circuit. Operation of relay C also opens circuit of relay A to de-energize the chain. Successive energizations occur if the relay L remains actuated. The relays have time delay opening to ensure a sufficient interval between successive movements of the switch to allow the generator to respond and thus prevent hunting. If the voltage is too high the relay R is energized and closes switch r1 so that relay SU is energized to operate the switch S 1 in the reverse direction. When the switch S reaches either limit a switch S2 moved simultaneously therewith actuates either a relay D or a relay V according to which limit it reaches, operation of either of these relays changing the circuit connections so that the switch F1 is operated to give a large change. If the voltage variation is such that the switch F1 reaches either of its limits a warning lamp K or H is energized by means of a switch F2 moved simultaneously therewith, and the circuit of relay A is broken by means of a relay E. If desired the operation of relay E may complete the circuit of an alarm bell BE. The arrangement may be used to regulate current.

Abstract: 1419404 Determining leakage of fuel elements EXXON NUCLEAR CO Inc 3 April 1973 [10 May 1972] 15821/73 Heading G6C In testing for leakage of a nuclear fuel pin, a flexible diaphragm 113 in the pin is excited into vibration, and the rate of decay of the oscillations measured. The diaphragm 113 is backed by a rigid disc 114 provided with one or more apertures 115 through which fission product gases can pass from plenum 109 to cause the diaphragm to flex, as shown, into a cavity 108 defined between the diaphragm and the lower, concave surface 112A<SP>1</SP> of an end-cap 112. A rod 117 of magnetic material rests on the diaphragm 113 and is movable in a cavity 116 in the end-cap. To perform the test, the rod is raised by magnetic means external to the pin and then released so as to impact the diaphragm to set the latter in vibration. The number of bounces of the rod on the diaphragm, as determined by acoustic sensors external to the pin, indicate the degree of flexure of the diaphragm and hence the gas pressure applied to its lower surface. Prior to commencing the test, which is carried out with the pin in situ in a BWR reactor, control rods are inserted to reduce fission product formation and to allow gas in a leaky pin to escape.

Title: Improvements in frequency controlling and stabilising means in radio-apparatus and the like
IPC: H03C3/02
Filed: 1943-10-07
Abstract: 579,567. Automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and CANTELO, H. R. Oct. 7, 1943, No. 16450. [Class 40 (v)] [Also in Group XXXV] In a combined transmitting and receiving radio apparatus, the transmitting oscillator is stabilized in frequency by association with a standard oscillator, a discriminator and a frequency-controlling device ; and during reception, the transmitting oscillator is associated with the standard oscillator to produce a resultant oscillation for mixing with the received waves to produce an intermediate frequency which, when varied from its normal value, exerts a correcting action on the transmitting oscillator. As shown in the drawing, applied to a frequency-modulated system, the transmitting oscillator O1 is modulated by the signal AF in the reactance valve CV, and is multiplied in frequency at M1 before passing to an amplifier A1 and aerial AT. A standard oscillator 02 feeds a multiplier or harmonic selector M2 the output of which is combined in a frequency changer FCl with the output of the oscillator O1. When the switch S is on the transmitting contact T, the difference frequency from FC1 is fed to an amplifier IFA and to a limiter discriminator DL, which supplies a correcting voltage to the reactance valve CV should the oscillator O1 depart from normal. During reception, the multiplied frequency from O1 and M1 is mixed in the frequency-changer FC2 with the multiplied frequency from 02 and M2 and a resultant frequency is mixed in the frequency-changer FC3 with the received wave from AR. The beat passes through the switch S and amplifier IFA to the discriminator DL, and any drift in the incoming frequency is compensated by applying the D.C. component of its output to the reactance valve CV to shift the frequency of the source O1, whilst the A.C. component passes to the signal receiver af. The above arrangement is only applicable to systems using a single operating frequency, but in a modified arrangement, Fig. 2 (not shown) provision is made for the use of any selected frequency within a wide band. Specication 551,472 is referred to.
