Title: Improvements in the purification of sugar solutions
IPC: C13B20/14
Filed: 1924-07-09
Abstract: Sugar solutions are purified by filtering them through zeolites or like compounds which substitute alkaline earths for the alkalies of the solutions and then through a further quantity of similar compounds which are stated to remove the dissolved alkaline earths and other impurities by absorption.  Suitable compounds can be prepared by precipitating dilute solutions of salts of aluminium, iron, or alkaline earths by means of waterglass and treating the dried precipitate with a solution of the chloride of the appropriate alkaline earth metal.  A process of thus treating iron sulphate is described.

Filed: 1928-06-08
Abstract: 318,672. Marks, E. C. R., (Jasper, H. N.). June 8, 1928. Atmospherics, eliminating. - To eliminate interference from atmospherics, a wireless receiver comprises a main circuit coupled to the aerial circuit and tuned to the desired signals, and two side circuits S<1>, S<2> coupled to the main circuit and tuned differently from the main circuit. Since atmospherics affect all the circuits and the signals only the main circuit, the atmospheric disturbance can be eliminated relatively to the signal by neutralization in the output circuits. As shown, an aerial circuit 1, 2 is tuned to the signal frequency by a condenser 3 and is directly coupled to a detector valve 6. The side circuits, tuned by condensers 11, 15, are coupled to the main circuit by inductances 12, 16. Secondary windings 9, 18. 20 of output transformers 8, 17, 19 are connected differentially in the grid circuit of a valve 21, the plate circuit of which includes telephones or the like. According to modifications the input of the main circuit includes a single inductance (Fig. 2, not shown): a common high-frequency amplifier is used before the three circuits (Fig. 3, not shown); each circuit includes a high-frequency amplifier (Fig. 4, not shown); the inputs of the circuits are tapped from a common inductance (Fig. 5, not shown) ; the circuits are coupled electrostatically (Fig. 6, not shown); the balancing is performed at amplified high frequency.

Abstract: 695,672. Automatic speed and voltage control systems. GARRETT CORPORATION. July 16, 1951 [July 21, 1950], No. 16849/51. Class 38 (iv). [Also in Group XXIX] The voltage of an alternator driven by a turbine which also drives a hydraulic pump, is regulated by varying the speed of the turbine by varying the loading on the pump in accordance with the alternator voltage. The turbine C is supplied from an unspecified pressure source 12, and drives the alternator A, and the pump B. The source 12 also pressurizes the liquid reservoir 26 which supplies both the intake to the pump, and liquid under pressure for operating the control system. The output of the pump passes via a hydraulic accumulator 47, hydraulically actuated control valve 17, and pressure relief valve 45 to the supply conduit. A voltage responsive solenoid 42 controls the valve 37, which controls the valve 17, to vary the loading on the turbine and hence the voltage of the alternator.

Abstract: 543,436. Valves. COCKBURNS, Ltd., RODGER, J., and GRANT, T. Nov. 25, 1940, No. 16860. [Class 135] An emergency automatic shut-off valve comprises a valve chest 1, a cylindrical liner 11 with lateral ports 13 fitted therein, an axially movable valve 6 guided within the chest 1 and engageable with a seat 8 on the end of the liner, and a piston 10 fixed to the valve 6 and movable within the liner. The chest 1 has inlet and outlet ports 2, 3 respectively. The chamber 14 above the piston 10 is connected through an adjustable needle valve 16 to a point on the outlet side of the valve, and a restricted duct 17 passes through the piston 10. In operation the fluid pressure built up in the chamber 14 is sufficient to resist the upward fluid thrust on the valve and piston. Should an excess fluid pressure drop occur across the valve the fluid pressure in the chamber falls accordingly and the valve closes.

Filed: 1919-07-09
Abstract: 152,401. Ashcroft, E. A. July 9, 1919. Magnesium chloride; double chlorides. - Hydrated magnesium chloride is converted into the anhydrous body by partial dehydration in a voluminous current of heated air, preferably dried, until the fusion point is mixed above 150‹ C., followed by treatment with a slow current of hydrochloric acid gas to complete the dehydration; during dehydration, fusion of the mass is to be avoided, and the product obtained is porous if a temperature of 500‹ C is not exceeded, and of a partly crystalline texture if the temperature is allowed to rise to incipient fusion, 650‹ C.; after dehydration the product may be fused. The magnesium chloride is preferably employed in the form of needle crystals such as are obtained by cooling a solution having a strength of 80‹ T., from 50‹ C. to atmospheric temperature. For carrying out the first stage of the process, the apparatus shown in Fig. 1 may be employed. In this, a retort A, C, suitably lagged, contains the material introduced through a lid a<2>-the larger lid a is for cleaning purposes,-and heated air supplied to a duct E passes into the retort through an annular gap d; the dehydrated material is removed by means of a rotating star wheel F, and is discharged into a churn connected in an airtight manner to the outlet. For the second stage of the process a separate apparatus as shown in Fig. 2 is preferably employed. The partly dehydrated material is introduced into a retort G, Fig. 2, enclosed in a furnace heated by tangential burners K, and comprising body sections G of silica glass and a charging-hopper H and outlet I of cast-iron; the hopper is provided with large and small lids, h, h<2> for cleaning and charging respectively, and in the outlet there is a screw or mill L in which any caked lumps are broken up. Hydrochloric acid gas is introduced by a pipe g<3> and passes into the annular gap g<2> formed by a depending skirt g; after passage through the material the gas is led away by a pipe h<3> to a condenser, and the concentrated acid so obtained passed to a generator in which it is liberated for re-use by treatment with concentrated sulphuric acid. The process is applicable to the dehydration of double salts such as carnallite. Specifications 152,402, [Class 41, Electrolysis], 152,403, and 152,879, [Class 41, Electrolysis], are referred to.
