Patent GB-419190-A (GB)
Title: Improvements relating to the production of treatment of cellulose derivatives
Filed: 1934-02-23
Abstract: Organic derivatives of cellulose in the solid strongly swollen and particularly fibrous state, are separated from fluids immiscible with water used in their preparation or after-treatment, by means of a displacement process using liquids which are indifferent towards the cellulose derivatives and are miscible with the liquid to be displaced.  The displacement liquid may be removed by evaporation, by dissolving out by means of water, or by distillation with steam.  The entire process may be carried out in one vessel which may be a diffuser, a displacement coil, or displacement centrifuge.  Suitable displacement liquids are acetone, dioxane, acetonitrile, benzene, toluene, benzine, carbon tetrachloride or other halogenated hydrocarbon, ether, esters, and the like, or mixtures thereof.  The displacement may be carried out from below or above, depending on the relative specific gravities of the displacement liquid and the liquid to be displaced.  When the displacement liquid contains high boiling constituents it is advantageous to carry out its displacement by water or steam from above.  An example is given in which a liquid, consisting of a mixture of acetic anhydride, acetic acid, sulphur dioxide, benzine, benzene, and some perchloric acid neutralized with sodium acetate, is separated from cellulose acetate prepared according to the process described in Specification 387,533, by displacement by means of a mixture of equal parts benzine and benzene.  The latter is sprayed over the cellulose acetate and the liquid which is displaced runs through the perforated bottom of the container and is collected in fractions.  The benzene-benzine mixture adhering to the cellulose acetate is removed by passing in steam and condensing and separating the distillate.  If further washing is necessary, this may be carried out in the same vessel, and if required, an alkali such as a bicarbonate may be added to the wash water.

In a radio transmitter for audio signals, power is supplied to the modulating and transmitting stages via a transistor controlled switch which is closed only in the presence of the audio signal. The audio signal from a microphone 1 is amplified at 2 and fed over a power amplifier 3 and modulating and transmitting stages 4 which are normally de-energized by open switch 11 in the lines to power supply 6. The audio output from 2 is also connected via impedance matcher 7 and threshold adjuster 12 to a peak detector 13 which is arranged so that only when the frequency of the input signal lies within the normal audio range does it provide an output voltage equivalent to the peak-to-peak value of the input signal. The output voltage from detector 13 is applied to a driver 14 which translates it into a trigger signal provided that the detector output is sufficiently large, i.e. representative of peakto-peak value of the input to 13. The trigger signal via a trigger 15 closes switch 11 until a predetermined time interval (determined by detector 13) after the end of the audio signal. Circuits 14, 15 and 11 are transistorized for speedy response and circuit details are provided, Fig. 2 (not shown).

Filed: 1916-05-03
Abstract: 100,679. Wrighton, W. J. June 15, 1915, [Convention date]. Annealing, tempering, and modifying the physical characters of metals.-A method of determining when a metal, such as steel, passes through a critical point, without the necessity of knowing its actual temperature, consists in observing the time of occurrence of an abrupt change in the rate of temperature-change of a point on its surface or in a medium external thereto, advantage being taken of the fact that the abrupt changes, such as j, k, t, in the temperature-time curve A for a point on or outside the surface of the metal take place at the same time as the abrupt changes o, p, q on the curve B for points inside the metal. The observation is made by means of a recording thermo-couple, or resistance pyrometer, or other apparatus sensitive to heat or radiant energy and capable of yielding results which enable a temperature-time curve to be plotted or visualized. The method is applicable to any heat-treatment of metal, such as hardening, quenching, or annealing.
