Abstract: 1,132,466. Control system for electrolytic production of aluminium, REYNOLDS METALS CO. Sept.8, 1965 [Sept.29, 1964], No.38442/65. Heading C7B. In an electrolytic cell for the production of aluminium wherein alumina dissolved in a molten salt bath is reduced to aluminium metal by passing electric current through said bath, the method of operation comprises producing a function indicative of the rate of change of cell resistance and controlling the feeding of alumina into the bath in dependance on said function in such a manner as substantially to counteract fluctuations in the cell resistance due to variations in alumina concentration in the bath. Since for any value of anode-cathode spacing the cell resistance has a minimum value when a specific alumina content is present in the cell (although the actual value of the cell resistance at this alumina content is dependant upon the anodecathode spacing), by considering the rate of change of the cell resistance at any given time the alumina content may be maintained at a preferred value at or near said specific alumina content without reference to the actual value of the anode-cathode spacing, similarly by adjusting the alumina content to the preferred value with reference to the rate of change of cell resistance, the anode-cathode spacing may then be altered to a predetermined value by adjusting said spacing until a corresponding predetermined value of cell resistance is reached. Whilst direct voltage is applied to the cell an alternating component appears superimposed on the direct voltage and by detecting variations in this alternating component, upset conditions within the cell e.g. caused by maladjustment of the anode blocks or by sludge accumulations, may be detected. The feedrate of alumina to the cell may be varied by varying the periods between feeds or by alternating between a high rate and a low rate of feed, one higher and the other lower than the rate of consumption thereof. Reduction Cell. The reduction cell shown comprises a steel shell 11 lined with an insulating layer 12 and carbonaceous lining 13 in which are embedded iron rods 18 which are connected with a cathode bus-bar 19, the cell containing in operation a pool of molten aluminium 14 and molten bath of alumina-containing electrolyte 15, covered by a crust 17 consisting of frozen electrolyte containing additional alumina. Suspended above the cell are a mechanical alumina feeder 24 supplied from a bin 23, and individually adjustable pre-baked carbon anodes 16 removably attached to bridge bus-bar 22.

Abstract: 1,226,125. Data processing. GENERAL ELECTRIC CO. 11 July, 1968 [14 July, 1967], No. 33070/68. Heading G4A. A data processing system comprises a processing unit which fetches instruction and operand words from memory and if appropriate sends them to an arithmetic unit (e.g. floating point), execution of an instruction by the arithmetic unit being overlapped with a further instruction fetch and performance by the processing unit of any address modifications required by the further instruction, the state of the arithmetic unit being tested by the processing unit on completion of the address modifications to cause the processing unit to wait or proceed according to the result of the test. The processing unit, which includes an adder and instruction decoder, proceeds (sending the instruction and operand words to the arithmetic unit if appropriate) when the arithmetic unit is no longer busy on the previous instruction, but only after performing an interrupt subroutine if a signal from the arithmetic unit indicates an attempt to divide by zero or an exponent result exceeding its limits (positively or negatively). The floating-point arithmetic unit includes an adder having exponent and mantissa portions, an instruction decoder, uses a control count to terminate operations, and is also capable of fixed-point operations. It specifies to the processing unit the number of operands to be accessed for the current instruction.

In apparatus for recognising a gas by measuring its thermal conductivity using a heated temperature sensitive resistor exposed to the gas, an additional current is fed through the sensor resistor to maintain its temperature and resistance substantially constant, this current being indicative of the gas thermal conductivity. As shown, Fig.3, two temperature-sensitive resistors Ref and Sens are connected in a double bridge network, resistor Sens being exposed to the test gas, and resistor Ref used to compensate for changes in general ambient temperature. Each bridge is initially separately balanced. When Sens is exposed to the test gas, an unbalance occurs in the left hand bridge, which is amplified at F and a current Y is fed into the right hand bridge, the additional current through Sens opposing the change in its temperature and resistance to produce an overall balance. The current Y is recorded at S and is indicative of the thermal conductivity of the test gas.
