Title: Detection of anode maladjustment in an alumina reduction cell
IPC: C25C3/20
Filed: 1974-09-17
Abstract: 1476695 Aluminium production by fusion electrolysis REYNOLDS METALS CO 17 Sept 1974 [17 Sept 1973] 40477/74 Heading C7B In an alumina reduction cell, Fig. 1, maladjustment of an anode 11, which is allowing. current to be transmitted without contributing to the reduction, such as when the anode is, incipiently, grounded, is detected by comparing a measured value representing the number of sinusoidal fluctuations occurring in the anode current within a given time interval with a reference value representing the number of fluctuations due to formation and release of gas bubbles 32, 33 when the anode is correctly adjusted and generating a signal when the measured value is less than the reference value i.e. indicating a lower frequency fluctuation. The measured value may be obtained by producing a stem voltage, e.g. from leads 38, 40 on each Cu stem 12 connected by metal stub 14 cast in each C block anode 11, varying with the anode current, and preferably filtered to remove fluctuations at frequencies above and below a selected range, converting the varying voltage fed via leads 201, 202, Fig. 2, and amplifier 208 into a sequence of pulses having a frequency proportional to the fluctuation rate in current, in pulse shaper 203 and counting the pulses over the time interval in counter 213. The reference value may be developed from the voltage by use of a voltage to frequency converter 205, a digital counter 211. A digital comparator 219 is connected to the counters 211, 213. The anode stems 12 are connected to anode bus 16 by clamps 18 and lifted by motor driven bridge jack 19 attached to the cell frame 21. The C cathode 26 contacting the molten Al 30 are connected by collectors 24 to cathode bus 23.

Abstract: 1,272,748. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 7 Aug., 1969 [26 Aug., 1968], No. 40787/68. Heading G6C. In a sodium cooled, fast breeder reactor, a layer of frozen sodium is formed over the internal metal skin of the concrete pressure vessel.

Title: Improvements in or relating to electric rectifying systems
Inventor: ROBINSON KENNETH ARTHUR
IPC: H02M1/14
Filed: 1966-09-13
Abstract: 1,203,763. Smoothing D.C. THORN AUTOMATION Ltd. 13 Sept., 1967 [13 Sept., 1966], No. 40938/66. Heading H2F. In a rectifying system having output terminals connected to a capacitor C for smoothing the output, the capacitor C is allowed to charge via a diode D 1  whilst the rectified voltage is approaching its peak value and a gate Th 1  is so arranged and controlled as to connect the capacitor directly via the gate across the output terminals at a predetermined interval after the rectified voltage has passed its peak. With the thyristor Th 1  turned OFF capacitor C charges from period A (Fig. 3, not shown), when the rectified supply voltage equals the load voltage until the peak voltage is reached (at B). The capacitor is then prevented from discharging until the thyristor Th 1  is fired (at D) and continues to discharge until the thyristor is switched OFF (at C) when the voltage in the next half cycle reaches a value corresponding to that (at A) when the capacitor begins to charge. The thyristor may be arranged to fire whenever the voltage across the load reaches a preset value after its peak or it may be time controlled so as to fire in a predetermined phase relationship after the peak of the alternating current supply.

Title: Improved glide path guidance means for aircraft
IPC: B64F1/20
Filed: 1961-11-15
Abstract: 971, 003. Visual landing aids for aircraft. COMMONWEALTH OF AUSTRALIA. Nov. 15, 1961 [Nov. 16, I960], No. 40943/61. Heading G4F. A glide path indicator for aircraft comprises a plurality of spaced lights parallel to a runway, so that the lights when visible to the pilot of an approaching aircraft appear in a line to him, the lights being provided with cut off arrangements so that each light is visible to the pilot only between a particular range of angles of inclination of his line of sight to that particular light. This range of angles differs for different lights so that the num - ber of lights in the line visible to the pilot provides glide path information for him. In one embodiment of the invention (Fig. 1) two longitudinal lines of lights, one each side of a runway, are arranged spaced equally about a transverse line 12 of permanently visible lights situated level with the aiming point 13 of the runway. The lights are shuttered in such a way that should the pilot be approaching the runway above the glidepath he will see some of the lights beyond the transverse line in the longitudinal line, the number depending on the amount of error in his path, and he will observe a display as in Fig. 4. Similarly if he is below the glidepath he will see only these lights before the transverse line (Fig. 5), and on the correct path he will see none of the longitudinal lights at all (Fig. 3).
