Abstract: 1,176,565. Breaking metals. NUCLEAR DESIGN & CONSTRUCTION (1966) Ltd. 30 May, 1968 [1 June, 1967], No. 25387/67. Heading B3E. [Also in Division G6] Apparatus for dismantling a spent fuel element string 14 consisting of a number of fuel elements mounted on a tie bar 15 connected to a standpipe shield plug 16, includes means for applying intense heat to a selected point on the tie bar to raise its temperature to that approaching melting point and applying tension to the tie bar to part it. As shown, the apparatus comprises a shielded vessel 1 having a tube 3 suspended from a platform 2 the fuel element string 14 being lowered into the tube by a grab (not shown) through a pipe 4 closed by a valve 5. The string 14 is supported by a sleeve 13 movable along the tube 3 by a chain elevator 21. A tie bar puller 6 has a passage 7 leading to a magazine 8 for containing parted lengths of the bar. The bar is longer than the combined length of the fuel elements and is retained at the top end by a shield plug 16; hence, by adjusting the tube 3 a length of the bar may be exposed either at the lower end (as shown) adjacent the retaining nut 22 or at the top end adjacent the lower surface of the spiral neutron shield portion 17 of the plug 16. A heating source, e.g. a water-cooled induction coil (Fig. 2, not shown) is placed around the exposed length of the bar to heat it in the region 1000-1200 C., the puller 6 then being operated to part the bar. The first parting is made at the top end to separate the bar from the plug 16, the second and subsequent partings being made at the lower end, the bar being progressively pulled down through the string by the puller 6. The parted bar lengths in the magazine 8 are sent to a disposal void through a pipe 11.

Title: Measuring direct current
IPC: G01R19/20
Filed: 1975-04-03
Abstract: 1488262 Measuring D C current T I (GROUP SERVICES) Ltd 3 April 1975 [11 June 1974] 25752/74 Heading G1U A D.C. current to be measured flowing in conductor 6 linking the core of a saturable transformer 1 induces a constant flux, which sets the mean level on which a varying flux due to an alternating current in a primary winding 2 is superimposed. Since the magnitude of the A.C. is enough to saturate the core, voltage pulses are induced in a secondary winding 3 at the zero crossing points only. The spacing of the pulses in each cycle is determined by the mean level of the flux, i.e. by the D.C. current in conductor 6. An amplifier 7 connected as a bi-stable flip-flop converts the pulse pairs into a pulse train whose width is proportional to the D.C. current. This is averaged 8, amplified 9 and fed to a compensating winding 4 on the transformer to oppose the flux due to the current being measured. The amplifier 9 output current is thus automatically adjusted to cancel the measured current, resulting in evenly spaced output pulses from winding 3. A network 11 operates such that if no pulses are produced e.g. if the mean level is so high as to result in a unipolar flux, the amplifier self-oscillates, thereby "hunting" to bring the flux to a detectable position. In a modified embodiment , Fig. 3 (not shown) the primary, secondary and compensating windings are combined into one. The feedback current is fed to one input of a summing amplifier whose other input receives the A.C. signal and whose output feeds the transformer winding, via a power amplifier stage. The device may be used for measuring automobile battery current, in which case mu-metal screening may be necessary for the transformer. Alternatively, the bi-stable input can be monitored to ignore spurious 'spiky' signals. The alternating current signal should have a substantially linear rate of charge around the zero-crossing points, e.g. a triangular waveform or a pure sinusoid.

Filed: 1972-06-06
Abstract: 1360563 Charging and discharging batteries J L FEAVER 6 June 1972 26283/72 Heading H2H A current integrator used in a battery supply system comprises a cam and switch device h driven by a reversible D.C. motor m by means of a pulse switching regulator d in such a manner that the speed of the motor is proportional to the discharge current of the battery a. The discharge current from the battery a feeding a load j flows in a resistor b, the volt drop across which is amplified by a device c and fed to the regulator d which provides pulses which by way of a reversing switch f supplies the motor at a speed determined by the battery discharge current. Rotation of the motor m drives a cam from its zero position closing the switch h in the process, the movement of the cam being a measure of the amount of discharge of the battery. To recharge the battery the switch g is closed, manually or automatically, and the switch f changed over. If the charging supply is connected between e, x the motor runs at a fixed speed in the reverse direction until the cam reaches the zero position, thereby opening switch h and terminating the charging process. If the charging supply is connected between e, y the motor will run at a speed dependent upon the charging current since such current flows in the resistor b. In this latter case the motor m is connected across a diagonal of a transistor bridge circuit. Means may be provided to ensure trickle charging of the battery.
