Patent GB-2073953-A (GB)
Title: High power current limiter or commutator device and resistive element thereof
IPC: H01C1/026
Filed: 1981-04-07
Abstract: A high power current commutation device for use with electrolytic cells to permit the system current to be shunted from the cell, and to thereafter be commutated back through the cell, employs a plurality of parallel path vacuum switches 18, with at least one vacuum switch being serially connected to a resistor 22 which increases in resistance with temperature and prevents switch damage due to excessive arcing. This resistor has a specific heat characteristic and thermal time constant such that current through the resistor will result in a potential drop across the resistor exceeding the electrolytic cell back potential to thereby commutate current back through the cell. A specific resistor design for use in the current commutation device is detailed. <IMAGE>

Patent GB-2091135-A (GB)
Title: Method of and apparatus for treating liquors by magnetic filtration
IPC: B03C1/015
Filed: 1981-10-29
Abstract: Treatment of liquors by magnetic filtration is made effectively by accurately controlling the ferrous/ferric ratio of iron ions in the liquor by adding a reducing agent. This has the effect that when the iron is precipitated, it is precipitated in the form of magnetite which is susceptible to high efficiency magnetic filtration. In the absence of control of the ratio, between 0.4 and 0.6, ferrous or ferric hydroxide might be precipitated and this is difficult to handle. Other contaminants are coprecipitated with or adsorbed by the iron floc. Measurement of the solution potential, between 0.35 and 0.4 volts, is used to determine the ferrous/ferric ratio. The apparatus includes a treatment vessel 2 with a solution potential probe 5, supply lines 3 for reducing agent and 4 for precipitating agent, and a magnetic filter 7. <IMAGE>

Title: Control circuit for a fluorescent tube
Inventor: MARSHALL RICHARD SIDNEY
IPC: H05B37/02
Filed: 1983-11-21
Abstract: The invention relates to a control circuit connected to an electronic ballast of a fluorescent tube. The control circuit comprises a gating circuit 44 having a plurality of stable states and a detector 54 for applying to the gating circuit 44 a triggering signal indicative of the presence of mains supply voltage at the fluorescent tube. The gating circuit changes state in response to brief interruption of the mains supply to the tube and the operation of the ballast is enabled or inhibited in dependence upon the state of the gating circuit 44. When fitted to some tubes in a room, the control circuit allows only some of the tubes to be switched on selectively without altering the wiring installation. When first the wall switch is operated only tubes without the control circuit are switched, whereas a brief interruption of the mains supply by the common wall switch will also switch on the tubes provided with the control circuit. Sets of tubes may be responsive to different numbers of mains interruptions. <IMAGE>
