Title: Improvements relating to measurements of magnetic fields
IPC: G01R33/04
Filed: 1945-04-18
Abstract: 590,678. Magnetic tests and measurements. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, BUTTERWORTH, A., TURNEY, A., and E.R.A. PATENTS, Ltd. April 18, 1945, No. 9743. Addition to 562,735. [Class 37] A modification of the recording magnetometer described in the parent Specification has means for separating the set of values when the auxiliary field is assisting the field under investigation from the set of values when the auxiliary field is opposing the field under investigation attained by arranging the circuits so that when the auxiliary field is in one direction, one condenser is charged by the magnetometer output and another condenser is charged when the auxiliary field is in the opposite direction. The two condensers are in series so that the voltage across them represents the difference in voltage obtained from the sensitive elements of the magnetometer under the two conditions, and this voltage is utilized to produce the deflection of the recorder. The elements 1 ... 13 and 15 ... 19 are arranged as described in the parent Specification. The output from the rectifier-amplifier 13 charges one or other of two condensers 28, 29 according to the direction of the auxiliary field of the coils 15, 16. The difference between the potentials to which the condensers 28, 29 are charged is applied between the grid and cathode of a valve 31. The two valves 30, 31 form a bridge-connected valve voltmeter, the third arm of the bridge being formed by a potentiometer 32, a resistance 33, and a part'34a of a potentiometer 34 and the fourth arm by a resistance 35 and the other part 34b of the potentiometer. A meter 73 and shunt 74 or a current recorder 72 is connected across the bridge network between the cathode of the valve 31 and the slider of the potentiometer 32. The necessary switching operations for separating the sets of values stated and for reversing the auxiliary magnetic field are carried out by means of a trigger circuit including three electromagnetic relays 41, 42, 43, each operated by the change in anode current of a valve 38, 39, 40, the relays and valves being crossconnected so that the relays are operated in sequence. The time intervals between successive relay operations in the sequence are controlled by the valves of grid condensers 100, 102 and of the resistances 99, 101 through which they are charged. A number of interlocked manually-operated three-way switches 48, 49, 50, 51, 52, 53 are arranged so that the following circuit changes are made. First the relays 41, 42, 43 are stopped by interrupting the supplies to the relays 42, 43. Secondly, the centre point of the two storage condensers 28, 29 is earthed and the relay 41 energized, so that the output of the rectified amplifier 13 is connected to the input of the valve voltmeter 31. Thirdly, the output of the valve voltmeter is switched to a normal type indicating meter 19 for the purpose of making adjustments. Fourthly, the auxiliary magnetic field is reversed.

On movement to the left, liquid in chamber 8 is transferred to chamber 9 via bore 15, annular cavity 18, line 20 and valve 24. The next rightward stroke causes liquid to be discharged from chamber 9 via valve 26, and on the next leftward stroke excess liquid in chamber 8 is returned to reservoir 10 via valve 25. The spring loading on valve 26 is greater than that on valve 25.
Patent GB-727485-A (GB)
Title: Method of making thin uniform coatings
IPC: C03C17/00
Filed: 1952-04-18
Abstract: Uniform thin coatings are produced on solid articles by applying a liquid consisting of a solution of a film-producing substance, or a monomer substance capable of polymerization thereto, by letting it spread under the influence of gravity and by subsequent solidification thereof, the liquid spreading in a first phase within a protective chamber which is to a large extent isolated from the outer air so as to prevent or partially suppress evaporation of the solution, or polymerization of the polymer, and to limit disturbing currents of air, the solidification of the thin liquid film so obtained occurring only in a second phase, outside the protective chamber, by evaporation of the solvent, or by polymerization.  The protective chamber may be provided at its upper part with a passage adapted to the shape of the article being treated and it may be a direct continuation of the liquid container from which the articles are coated.  Its walls may be wetted by the solution or solvent, or gas enriched with the vapour of the solvent may be introduced into it.  The temperature in the chamber is kept at such a level that the viscosity of the liquid film remains practically unchanged during the first phase.  During its passage through the chamber, the liquid film may be exposed to radiation or to gases which produce physical or chemical changes therein, e.g. the precipitation of precious metals by the action of formaldehyde on solutions of their salts, or the decomposition of plumbous solutions by hydrogen sulphide, or of ferrous or aluminous solutions by ammonia, or photochemical decomposition or polymerization.  After such passage and outside the protective chamber, solidification of the coating may be accomplished by heating, e.g. by infra-red radiation or a current of hot air. Applications mentioned include the production of optical layers, or of conducting layers, e.g. of tin oxide or antimony oxide.  In an example, a glass plate or tube is drawn at a rate of 3 centimetres per second out of a solution which has been obtained by repeated evaporation of an aqueous solution of zirconium nitrate and to each 100 c.cs. of which a few drops of a wetting agent such as the solution of a salt of an alkylnaphthalenic acid have been added. Evaporation is prevented for a stretch of about 30 cm., when an even layer of hydrated zirconium oxide is obtained, which, when heated, changes to zirconia.  Layers of silicon dioxide may be similarly produced from sodium silicate solutions or solutions obtained by the saponification of organic silicon compounds.
