Title: Improvements in or relating to a method of recovering iron from iron amalgam
IPC: C25C1/06
Filed: 1959-04-21
Abstract: 880,769. Regenerating iron amalgam electrolytically. SIEMENS & HALSKE G.m.b.H. April 21, 1959 [June 11, 1958], No. 13508/59. Class 41. Iron amalgam, formed for example in the treatment of iron pickle liquors, is processed to recover the iron by treatment with ferric sulphate solution which is then in the form mainly of ferrous sulphate, and is used as catholyte in an electrolytic cell divided by a diaphragm, some iron being deposited on the cathode, and the electrolyte then passing through the diaphragm to the anode compartment where it is converted to ferric sulphate, and is re-cycled to the iron amalgam cell. The iron-amalgam is vigorously agitated with the ferric sulphate solution which may also contain ammonium sulphate and a wetting agent, at 40‹ to 100‹ C. and at a pH of 4 or less, for example by counterflowing the two liquids in a packed tower. The iron pickle liquor may be freed from mercury particles by treatment with copper chips, and then filtered to remove any free carbon. The primary (mercury amalgam) cell and the secondary cell may be connected electrically and shunted to balance the electrolytic efficiency of the two cells, and/or the outflow of anolyte may be controlled. U.S.A. Specification 1,970,973 is referred to.

Title: Improvements in or relating to electronic regulating apparatus
IPC: G05D23/24
Filed: 1954-05-10
Abstract: 759,553. Automatic temperature control systems. GARRETT CORPORATION. May 10, 1954 [June 4, 1953], No. 13532/54. Class 38 (4). In a system for automatically maintaining a variable at a desired value increase or decrease of the variable is selectively controlled by differentially connected electronic circuits to one of which a signal responsive to error in the magnitude of the variable is applied and to the other of which a pulsed signal is applied. Deviation of the temperature of an aircraft cabin from a desired value influences a temperature-variable resistor 16, Fig. 2, within the cabin to unbalance a D.C. bridge circuit 30 and thus apply a voltage through a potentiometer 34 to the grid circuit of a triode valve 37a. Valve 37a shares a common cathode resistor 41 with another triode valve 37b so that the conductivity of the two valves is affected in opposite senses. As a result, through positive feedback amplifiers 55a, 67a and 55b, 67b respectively, the energization of relays 72 and 75 is affected differentially so that, if the temperature deviation is sufficient, the appropriate relay is operated to close contacts 72b or 75b and run an electric motor 15 in the direction necessary to correct the cabin temperature by moving a valve (not shown) altering the proportion of hot air to cold air in a mixture supplied to the cabin. Simultaneously with the operation of motor 15 closure of a contact 72a or 75a applies a voltage of one polarity or the other to charge a condenser 82 through a resistor 84 until the voltage thus applied to the grid circuit of valve 37b reaches a value at which its effect on the energization of relays 72 and 75 is such as to stop motor 15. Condenser 82 then discharges through resistors 83, 84 reducing the voltage until motor 15 is started again. Motor 15 is thus operated intermittently until cabin temperature is restored to the desired value, the periods of operation diminishing as the temperature error is reduced. An anti-hunting effect is produced by a pair of temperaturevariable resistors 18, 19, having different thermal inertia, which respond to changes in temperature of the mixture of hot and cold air supplied to the cabin and modify the voltage applied to condenser 82. A resistor 17 responsive to the temperature of the air mixture supplied to the cabin limits that temperature by controlling the voltage applied to a triode valve 88 so that a diode 98 becomes conductive when the limit is reached to lower the voltage applied to the grid circuit of valve 55a.

[Class 17 (ii)] [See also Group VIII] Complementary inner and outer sole members 39, 40, Figs. 8 and 14, are formed from a single blank by first forming a rounded sole with one or more incisions therein to define the margin of an insole and then splitting it within the depth of the said incisions. The incisions may be made before, or during the preliminary operations associated with the sole rounding operation. If desired, prior to the splitting operation, the ball portion of the blank may be depressed, in which case the blank is split at or above the level of the depression, which is subsequently flattened out. A combination pattern or template 20, Fig. 1, for a sole rough rounding machine, and cutting die, the blades 22 of which make an incision to define the contour of the insole on the blank 27 when such blank is pressed between the clamp of the rounding machine and the pattern 20, may be employed in the preparation of the sole members. The blank is then placed between pressing dies to depress the central ball portion and is then passed through a leather splitting machine, Fig. 8, a backing 36 of durable flexible material, corresponding in form to the sole member, being employed to maintain the shape. The depression 35 in the outer sole member 40 may be forced back into its original position after the upper has been lasted on the insole on a last, as shown in Fig. 14. In a modification, the depression may be formed by providing the clamping member and pattern of the sole rounding machine with a suitable projection and depression, and, as before, with blades, which may project both above and below to permit of its use to form the sole portions of a mated pair of shoes, the contour of the insole being then performed simultaneously with the depression.

Abstract: 1,164,894. Image intensifier tubes; electron multipliers. MULLARD Ltd. 29 March, 1967, No. 14225/67. Heading H1D. In an electronic imaging tube comprising a photo-cathode P spaced by a symmetrically disposed electron optical system from a channel intensifier device I, the channel intensifier is a secondary-emissive electron multiplier device which includes a plate, with conductive input and output layers E1 and E2 on opposite surfaces, and, passing through the plate, a large number of elongated channels all of which are parallel and inclined at a uniform angle # to the plane passing through the axis Z-Z and extending at right angles to the plane of the figure (termed the second main axial plane) such that none of the principal rays, which are the paths of those electrons leaving the photocathode at right angles to be brought to a focus in the focal plane F in front of the channel intensifier, is parallel to the axis of the corresponding channel. As shown in Fig. 3, the range of values for the angle # between a principal ray and a channel axis as measured from the channel axis never becomes or passes through zero, so that the formation of a dark spot is avoided by preventing electrons from being able to pass straight through a channel without undergoing any multiplication. In a particular example given the angle of inclination of the channels # is 15% and the angle # varies from 3 degrees at one edge to 27 degrees at the opposite edge of the channel intensifier. The imaging tube may be an image intensifier or image converter tube with a luminescent screen S which may be suitably biased to accelerate the electrons after they have left the field in the channels, and the electron-optical system may be of the diode type with a conical anode A electrically connected to the input layer E1 or triode type when not so connected. The channel intensifier I may, as described in Specification 1,164,895, be curved with the concave face towards the photo-cathode to more nearly conform to the shape of the focal plane F, and shaped fibre optic units (FO1) and (FO2) may be employed between the object and photo-cathode and as a faceplate for the viewing screen S, which may also be curved, Fig. 5 (not shown).
