Patent GB-758083-A (GB)
Title: Improvements in or relating to apparatus for sizing and counting particles by the intercept method
Inventor: HAWKSLEY PETER GERALD WINCHCOM
IPC: G06M11/04
Filed: 1951-05-11
Abstract: 758,083. Photo-electric particle counter. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 12, 1952 [May 11, 1951], No. 11224/51. Class 40 (3). In a device for counting and sizing dispersed particles the field containing the particle is scanned along a straight line or a line of large radius of curvature compared to the particle size means to the presence of a particle controlling means to record the length of the intercept of the particle with the line. An image of the particles dispersed on a microscope slide may be projected on to a screen. The screen is opaque and provided with a pinhole behind which is a photo-cell. The slide is moved in a straight line for example by mounting it on an arm attached to a synchronous motor. In an alternative arrangement a spot of light produced on the screen of a cathode-ray tube may be reduced in size by a microscope and focused on to the particle field behind which is situated a cell. The cell may receive light reflected from the field. The output pulses from the photo-cell, the width of which depends on the particle length may gate a standard oscillator or pulse generator so that the number of pulses produced by the oscillator until the photo-cell output pulse ceases, is a measure of the particle width. The pulse generator may feed a bank of counters which operate in succession counting one pulse each. Thus, all intercepts operate the first counter, all intercepts two pulses by the second and so on. In an alternative arrangement a relay controlled by the photo-cell connects the pulse generator to a uniselector which is set in motion and completes a rotation. An auxiliary voltage is connected to the uniselector arm which operates in turn each counter to which the uniselector arm is connected until the photocell output pulse ceases. In the arrangement of Fig. 1, the photo-cell controls the operation of a gating circuit 2 which connects standard pulse generator 3 to an impulse transfer circuit in which counters are switched to the anode circuit of each valve by a subsidiary electronic relay so that the counter attached to the valve is the only one that records. In an alternative arrangement (Fig. 2, not shown), the output pulse from the photo-cell is compared in length with timing pulse of known duration, a comparison circuit operating a counter only when pulses longer or shorter than the timing interval are produced.

Abstract: 755,674. Interrupters. EMAG ELEKTRIZITATS-GES. April 22, 1954 [April 23, 1953], No. 11676/54. Class 38(5) An electric switch for rectifying A.C. comprises co-operating rolling contacts of different degrees of hardness, whereby the tendency of the conducting material to creep is reduced. Where a contact path comprises conducting and non-conducting parts both may have similar degrees of hardness. The co-operating contacts may be made of similar materials of different degrees of hardness, or of different materials. Hard silver, eutectic silver and copper alloy, electrode, silver and beryllium bronzes and sintered materials are specified. At least one contact surface may be coated with non-oxidizable material such as rhodium, silver or a material with a conducting oxide. The contacts may be resiliently mounted and/or applied to their supports by galvanizing, rolling soldering or welding. They are preferably but not always of non-magnetic material. Their surfaces may be roughened by grinding or abrading or by mutual slip during operation. In a switch for rectifying a three phase supply, two roller contacts 1, 2 on shafts 12 carried by levers pivoted at 14 to a rotatable member 15 bear on the internal surfaces of two rings mounted one above the other, each comprising three conducting segments 8, 9, 10 separated by non-conducting segments 11. The conducting segments of one ring are connected together by conducting ring 18 and of the other ring to the three input phases, and the rings may be mutually rotated to vary the length of the conducting periods in each phase. The pressure between the contact surfaces is determined by the tension of springs 26 and the positions of adjustable weights 23 which assist and oppose respectively the centrifugal forces on rollers 1, 2. The contact surfaces are cleaned by scrapers 27, 28.

Title: Improvements in and relating to the recovery of spinning bath liquors
Inventor: BROOK BASIL WILLIAM
IPC: D01F6/18
Filed: 1955-04-25
Abstract: Spinning baths which have been used in the manufacture of polyacrylonitrile threads and which contain water and one or more salts, or water, a lower monohydric alcohol and one or more salts, particularly thiocyanates, are rendered suitable for re-use by treating them with activated carbon so as to remove substances causing discoloration of the threads and then distilling off water (or an alcohol and water) from the liquor to produce a concentrated aqueous solution of the salt or salts.  In an example, filtered used spinning bath liquor containing 9 per cent of sodium thiocyanate, 86.9 per cent of water, 4 per cent of methyl alcohol and coloured contaminants is passed at 18 DEG  C. through a column of 16-22 mesh granular activated carbon and the methyl alcohol is recovered from the colourless effluent by distillation.  The residual liquor is then further distilled to give an aqueous sodium thiocyanate solution sufficiently concentrated for the preparation of further polyacrylonitrile spinning solution.  The exhausted granular carbon is regenerated by boiling in 1 per cent aqueous caustic soda solution for 30 minutes followed by washing with dilute sulphuric acid and water. Specifications 672,775, 714,530, 729,472 and 732,135 are referred to.
