Abstract: 1345254 Electrolysis cells ORONZIO DE NORA IMPIANTI ELETTROCHIMIEI SpA 19 April 1971 [23 April 1970] 24224/71 Heading C7B An electrolytic cell comprises two or more cell units A, B, C each having a metal anode and metal cathode formed with a respective series of fingers 4, 6 which are nested to provide a uniform spacing therebetween, there being provided for each cell unit a container 14 for supplying the electrolyte, and discharge means for the anodic and cathodic cell unit products. The anode and cathode fingers may be arranged in a wave form with the anode fingers made from a mesh of a valve metal e.g. titanium or tantalum and the cathode fingers from steel screen with steel reinforcements 12 and covered with an asbestos diaphragm 6a. In some cells the anode may also be covered with a diaphragm. The anode plate 1 is made of steel covered with a valve metal lining 3 and the cathode plate 1a from steel also covered with a lining. The anode fingers are bolted to the anode plate and the cathode fingers welded to strips 7 extending from the cathode plate. The cell units are held together by tie rods 21a and mounted on beams 19. Terminal plates 2, 2a are located at the ends of the cell. In a cell used for the electrolysis of sodium chloride brine, chlorene released at the anode fingers 4 passes through the electrolyte to passages 13 and escapes via the containers 14. Pipes 16 from the containers feed the brine to the space between the fingers. Sodium hydroxide and hydrogen are released at the cathode fingers in the space between the fingers and cathode plates 1a. The hydrogen rises into the top runs of square-section pipes 9 surrounding each cell unit and escapes through outlets 17 while the depleted brine containing the sodium hydroxide flows into the side legs of pipes 9 and escapes through outlets 18. In a modified cell unit, Fig. 7, titanium fingers 30 are mounted on and pass into a titanium box 31 which is welded or bolted to a steel box 32 to which screen cathode fingers 33 are secured. In a cell a number of cell units are nested and electrolyte introduced into boxes 31 through inlets 34.

Abstract: 1403646 Electrically-propelled vehicle with alternative current supply means LTV AEROSPACE CORP 22 May 1973 [7 June 1972] 24288/73 Headings B7L and B7H An electrically-propelled vehicle 10 has current collectors 16 comprising contact brushes 17 which can receive power either by contact with respective power rails 14 in a guideway 11, or by connection via cable 13 to an alternative power source such as a portable generator 19 when the collectors are covered by respective insulative shields 23, 23A (23B, 23C), control means being provided such that a switch (64), Fig. 6 (not shown), is opened to cut off supply from the source 19 unless all of the shields 23 &c. are fastened in position over the collectors 16. The shields 23 &c. are intended to overcome the risk of electric shocks when the vehicle 10 is used off the guideway 11, i.e. when powered by the source 19. Power from the source 19 is fed through the cable 13 and switch (64) to the brushes within the shield 23A by contact clips (62) mounted on the interior surface of the shield 23A, the clips (62) being similar to clips 31 which are mounted on the insides of the remaining shields. The various collectors are interconnected so that the power is fed to all the brushes where it is picked up by the clips 31 which are connected to sensing circuits 33. The circuits 33 are thus activated to indicate the presence of the respective shields and each send a rectified signal to a monitoring circuit (71), Fig. 6, which takes no action provided all of the signals are present. However, if one or more signals are absent indicating the absence of a shield, a logic circuit (72) of the monitoring circuit acts to operate a relay (69) which opens the switch (64) to cut off supply from the source 19 to the vehicle.

Abstract: 971,728. Automatic control of current and voltage. GENERAL ELECTRIC CO. Ltd. June 24, 1963 [June 28, 1962], No. 24955/62. Headings G3R and G3X. A constant current circuit 15 comprises input terminals 1, 2, output terminals 3, 4 supplying a load 14, a transistor 5 having its collector connected to terminal 1, its base connected to terminal 4 and its emitter connected over a Zener diode 6 and a resistor 7 to the terminal 2, and a resistor 8 connected between terminal 4 and the junction of components 6, 7. Any variation in the magnitude of the load current produces a change in the voltage across resistor 8 and a corresponding change in the bias supplied to the transistor 5 whereby the conductance of the transistor is varied in such a sense that the current flowing in the shunt path across the input terminals is so changed that the load current is restored to its previous magnitude. The load 14 is also connected to a voltage source 9 associated with diodes 10 and 11 connected as shown over a resistor 12 to an input terminal 13, the arrangement being such that the diode 10 is reverse-biased when the value of the load resistance is such that the potential of the output terminal 4 is lower than that of the source 9. If the value of the load resistance rises such that the potential of terminal 4 rises above that of source 9, the diode 10 becomes forward biased, and part of the constant current flows through it so as to return the potential of terminal 4 to a level below that of source 9; thus,the voltage across load 14 cannot exceed a certain value which is determined by the value of the source 9. Specification 877,496 is referred to.
