Title: Production of aqueous solutions of aluminium chloride
IPC: C01F7/56
Filed: 1947-10-30
Abstract: Acid, neutral or basic solutions of aluminium chloride are produced from granular alumino-siliceous materials by repeated percolation therethrough, whilst in gas-tight vessel or vessels, of hot solutions of hydrochloric acid and/or aluminium chloride, removing the solutions at the desired end point, washing the residue in situ by percolating therethrough a plurality of liquors of progressively weaker solutions from previous extractions and finally water, and then discharging the residue.  The HCl and steam evolved during reaction are condensed and such condensate may be used as washing liquor for the residue or as a digesting liquor.  If desired, strong HCl solution or gas may be added to a dilute condensate, wash liquor is partially neutralized digesting liquor, to give further digesting liquors.  The digestion may be under increased pressure, temperature or concentration.  The basicity of the aluminium chloride solution may be increased by adding aluminium metal to the liquor in the reactor.  Neutral or basic solutions of aluminium, potassium and iron may also be obtained when the starting materials contain the said metals by digesting them as above, and basic insoluble salts will not be formed provided the digesting solutions are free from sulphuric acid and sulphates.

Title: Process for improving rosin
IPC: C09F1/00
Filed: 1935-10-21
Abstract: The properties of rosin are modified by dissolving it in a small amount of a solvent inert to sulphuric acid, adding a strong aqueous solution of sulphuric acid, stirring so that a polymerizing reaction occurs progressively, cooling the mixture during the reaction to minimize decomposition, then separating the mixture into solvent and acid portions and recovering the modified rosin from the solvent. The melting point and the molecular weight of the rosin are thereby raised, and its iodine valve and acidity are reduced.  Gasoline is a suitable solvent, and sulphuric acid of 81 per cent strength or over is effective.  The reaction may be terminated by stirring in a large volume of gasoline, or merely by stopping the stirring.  The modified rosin may be recovered from the solvent by washing, followed by distillation or by extraction with sodium hydroxide.ALSO:The properties of rosin are modified by dissolving it in a small amount of a solvent inert to sulphuric acid, adding a strong aqueous solution of sulphuric acid, stirring so that a polymerizing reaction occurs progressively, cooling the mixture during the reaction to minimize decomposition, then separating the mixture into solvent and acid portions and recovering the modified rosin from the solvent.

Filed: 1938-10-06
Abstract: 520,081. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., SMITH, S. B., and FORBES, I. S. Oct. 6, 1938, No. 29030. [Class 40 (v)] In a direction-finding receiver, the pick-ups from a directional aerial and an omni-directional aerial are combined by a continuously-variable cyclic coupling and applied through a receiver proper to one deflection system of an oscillograph, deflections in another direction being produced by means actuated for a short period once per cycle of the variable coupling, the position of the period of actuation in the cycle being adjustable. In Fig. 1 the pick-up from the open aerial 28 is coupled by means of the coils 9, 11 with the output from the search coil 3 of a goniometer connected to a crossed Adcock aerial system, the combined output being applied through a receiver proper 22 to one deflection system 23 of a cathode-ray tube. Coil 11 is, constantly rotated by the motor 13 so that the coupling between the coils 9, 11 is varied sinusoidally and a linear sweep-voltage is applied to the other deflection system 20 of the cathode-ray tube from the time-base 19 for a short period per revolution of the coil 11 by means of the rotary switch 14, 16. The phase of the actuation of the time-base may be adjusted by varying the position of the slip-rings of the rotary switch. When the output from the search coil 3 is zero a symmetrical trace, Fig. 2a, is obtained on the cathode-ray tube but when the coil is rotated from this zero position, unsymmetrical traces, Figs. 2b and 2c, are obtained the asymmetry of which depends upon the sense of rotation. The sense is determined by observing whether the symmetrical trace changes to the form shown in Fig. 2b or Fig. 2c on rotating the goniometer coil 3 in a given direction. The search coil 3 is mechanically coupled to an indicating needle 7 and the bearing of the transmitter is. accordingly given by the reading of this needle when the coil 3 is adjusted to give the symmetrical trace. Telephones 24 are connected to the receiver 22 to enable communication signals to be received during the D.F. operation. In a modification (Fig. 3, not shown) the variable coupling is provided in the input from the directional aerial, the open aerial being constantly coupled to the receiver, in which case the symmetrical trace is of rectangular shape. It is stated that the systems also provide an aural indication of the bearing.
