Patent GB-961584-A (GB)
Title: Improvements in or relating to electrolytic capacitors
IPC: H01G9/00
Filed: 1961-12-08
Abstract: Ancillary members used for supporting or connecting to electrolytic capacitor electrodes are coated with material resistant to the corrosive action of the electrolyte before assembly with the electrodes.  The ancillary members may be wires, rivets, eyelets or washers but the coating of lead-out wires is specifically described. To produce these a continuous length of wire is degreased and then passed through a bath comprising a suspension of PTFE particles in water together with a wetting agent.  The resulting PTFE coating is then sintered by heat and the coated wire cut into portions to constitute separate lead-out wires.  A silicone resin may be used instead as the coating material, and the ancillary members will generally be of aluminium, which may be anodised before coating.

Title: Improvements in or relating to electric power supply arrangements
IPC: G05F1/573
Filed: 1960-12-22
Abstract: 970,642. Automatic voltage control systems. GENERAL ELECTRIC CO. Ltd., and J. HADLEY. Dec. 22, 1961 [Dec. 22, 1960], No. 44150/60. Heading G3R. Overcurrent protection for the series transistor in an automatic voltage regulator is effected by a current limiting circuit which tends to increase the impedance of the transistor when the load current reaches an upper limit, together with a circuit which responds to excessive voltage drop across the transistor to rapidly bias it to cut-off. The transistor 7 is connected in series between a supply rectifier 5 and the load and is normally controlled by an error amplifier 8 to maintain the load voltage constant. Amplifier 8 comprises an emitter-coupled pair of transistors which compare the output voltage with a reference Zener diode, and a further transistor to simplify the error signal. A transistor 15 responsive to load current, is arranged to conduct when the load current through resistor 14 exceeds a desired value so diverting base current from transistor 7 to increase the emitter/collector resistance. A Zener diode 19 is connected across the transistor 7 in series with the emitter/base path of a transistor 18. When, due to overload, the voltage drop across transistor 7 is sufficient for diode 19 to conduct transistor 18 conducts, thereby reducing the base bias of transistor 7 and so driving it to cut-off. In a modification, Fig. 2 (not shown) the base of transistor 18 is connected to a potential director connected across the D.C. input circuit, the lower arm of the director consisting of a Zener diode.

Title: Improvements in or relating to the production of so and/or sulphuric acid
IPC: C01B17/765
Filed: 1963-11-16
Abstract: Gases containing below 9% by volume of SO2 are catalytically converted to SO3 and/or H2SO4 by a process comprising (1) preheating part of the incoming SO2 by heat exchange with SO3 containing gases produced in a multistage converter, (2) addition of sulphur combustion gases to the incoming SO2 before entering the first catalytic layer of the multistage converter, and (3) absorption of SO3 before the gases are passed to the final catalyst layer, the quantity of sulphur used for the combustion being such that the SO2 content of the gases passed to the first catalyst layer of the converter does not exceed 9% by volume and that the heat of combustion of sulphur and the heat of oxidation of the SO2 so produced compensates for the heat loss by intermediate absorption of SO3.  A portion of the preheated incoming SO2 gas may be used for the combustion of sulphur and the remaining portion can be further heated by the partially catalysed gases from the first catalyst layer.  The hot sulphur combustion gases may be mixed with the incoming not preheated SO2 in such proportions that the temperature of the mixture is suitable for passing through a gas filter without cooling.  The multistage converter may have 3 catalyst layers. 3-4 kg. of sulphur per 1000 cubic metres (S.T.P.) of SO2-containing gas are burnt for each per cent the gas falls short of 9% SO2.

One of a plurality of symbols is selected from an array on a mask M (Fig. 1) by applying digitally coded signals to a deflector D1 to direct a beam of light 1 on to the symbol, a further deflector D2 directing the image of the symbol on to a position on photosensitive material 3 dependent on digitally coded signals applied to the deflector D2. A sequence of digitally coded signals is applied to the deflectors so that an alpha numeric character is built up on the material 3 which is then stepped so that the next character can be recorded. In one embodiment the deflector D1 comprises four cells (Fig. 3) each constituted by an electro optical crystal K the faces of which are covered by transparent electrodes and a birefringent crystal Q. The polarization of light passing through a crystal K is rotated through 90 degrees when an associated switch I is closed by the associated bit of the digitally coded signal. When extraordinary rays traverse one of the crystals Q the emergent beam is deflected in the direction indicated by the arrows. The light beam from the mask M is restored to its central path by a similar deflector D11, before being applied to the second deflector D2 which is also similar to deflector D1. Alternatively the deflectors may comprise only three cells the width of each birefringent crystal Q being twice the width of the preceding one (Fig. 4, not shown). The mask of Fig. 1 is then replaced by a rectangular one (Fig. 5, not shown).
