Patent GB-428610-A (GB)
Title: Improvements in and relating to the purification of crude nickel carbonyl
IPC: C01G53/02
Filed: 1933-11-11
Abstract: The purity of nickel carbonyl containing one or more impurities (including one or more other carbonyls mixed with it) is increased by lowering the temperature of the impure nickel carbonyl until it lies below the freezing point of either the nickel carbonyl or at least one impurity and above the freezing point of the other of these two substances and then separating the solid and liquid portions of the mixture.  The cooling may be continued until the bulk of either the nickel carbonyl or the impurity solidifies or the impure nickel carbonyl may be completely frozen and the frozen mass may then be partially thawed.  The impure nickel carbonyl may be cooled directly from the vapour phase but it is preferred to prepare first an impure liquid carbonyl.  A solvent or decomposing agent for the impurity may be added prior to the treatment.  This may have a higher or a lower freezing point than nickel carbonyl. For example, if oil is present and little or no water, water may be added which on freezing entraps the oil and suspended foreign matter, the purified liquid carbonyl being then removed, say by decantation.  In the removal of oil, a pretreatment by distillation or filtration may be carried out.  The amount of iron carbonyl in a mixture of nickel and iron carbonyl may be reduced by cooling, say to -20 DEG  C., until a substantial quantity of the mixture solidifies and then removing the liquid portion which contains most of the iron carbonyl.  If the impure nickel carbonyl contains cobalt carbonyl, it is preferable to separate this by distillation (the cobalt carbonyl remaining behind as the solid tri-carbonyl) before applying the present process.  On cooling a mixture of nickel and molybdenum carbonyl, pure molybdenum carbonyl separates out in increasing amounts until a temperature of about--20 DEG  C. is reached.  At this temperature nickel carbonyl containing a small proportion of molybdenum carbonyl solidifies. Successive cooling treatments may be employed, the carbonyl becoming purer at each successive treatment.  The Provisional Specification describes also an example in which water is added to a mixture of nickel, iron and cobalt carbonyls obtained by treating a copper-nickel-sulphur matte containing iron and cobalt with carbon monoxide at 250 DEG  C. and 250 atmospheres pressure, the mixture is solidified by cooling to -25 DEG  C. and the solidified product is allowed to stand at atmospheric temperature until the whole is liquid, two liquid layers being obtained, the lower of which consists of pure nickel carbonyl.

Title: Improvements in or relating to means for generating electrical saw-tooth oscillations
IPC: H03K4/16
Filed: 1938-10-31
Abstract: 520,460. Valve generating circuits. GENERAL ELECTRIC CO., Ltd., CHERRY, E. C., and CLAYTON, R. J. Oct. 31, 1938, No. 31458. [Class 40 (v)] In a saw-tooth oscillation generator in which a condenser 3 is charged (or discharged) -at a constant rate through a resistance 7, and is discharged (or charged) abruptly through a thermionic valve 1, the grid circuit of the latter includes a resistance 4 and condenser 5 in parallel, the time constant of which in conjunction with the rate of increase of anode voltage determines the frequency of oscillation, and an inductance 6 coupled to an inductance 2 in series with the condenser 3 in such manner that when the valve begins to conduct the grid voltage is made more positive and thus the discharging (or charging) of the condenser 3 through the valve is expedited. The valve 1 may be a multi-grid valve, synchronizing signals being applied to one of the additional grids. Current through the resistance 7 may be supplied through a pentode or like valve operating at constant current. The voltage derived from the condenser 3 may be amplified for application to the deflecting coils of a cathode-ray tube, and the amplifier may be enclosed in the same envelope as the oscillator, the two valves sharing the same cathode. For example, a triode-hexode may be adapted to serve the two functions. Specification 425,035 is referred to.

Abstract: 383,063. Resistance coatings and deposits; variable resistances. GRAMOPHONE CO., Ltd., Hayes, Middlesex, SARGENT, F. B., Thirlmere, Langley Road, Slough, Buckinghamshire, and FINNIMORE, T. C., 41, Trinity Road, Southall, Middlesex. Nov. 14, 1931, No. 31578. [Class 37.] An element for a variable resistance in which a large variation is produced when the contact arm is moved over one part of its surface and a smaller variation over another part, particularly for use as a potentiometer for volume control in valve apparatus, has a layer of conducting material applied to part of its surface. The resistance element may be formed of granular material such as graphite, granulated carbon, &c, mixed with a binder, and may be of arcuate form. On a part, for example one-half, of the surface is deposited a layer of conducting material such as gold. This may be deposited by exposure to cathode rays in a vacuum, the electrodes comprising copper tubing through which a cooling medium is circulated and which is encased in strip gold. The part that is not to be coated may be covered with fabric, from which any deposited metal may be recovered. A number of resistance elements may be mounted on a band and passed simultaneously across the discharge space. In the case of a resistance element comprising a strip of carbon-coated paper, the rear surface of the strip may contact with a cooled surface to prevent singeing. Contact with the element may be made by means of a resilient disc between the element and the wiper arm.
