Abstract: 641,007. Refrigerating. ELECTROLUX, Ltd. Oct. 31, 1947, No. 29078. Convention date, Nov. 28, 1946. [Class 29] In a continuous cycle absorption refrigerating system of the inert gas type having a generator comprising a substantially vertical flue tube 10 and a plurality of substantially vertical conduits one of which forms a pipe for a column of strong solution in free communication with the absorber vessel 14 through a liquid heatexchanger 13 through which it flows upwardly, said pipe communicating towards its lower end with a gas bubble pump, the expelled vapour is analyzed by passing it through strong solution in a substantially horizontal portion of the said pipe in counterflow. As shown in Fig. 1, strong solution flows from the liquid heat-exchanger 13 through an L-shaped conduit 16 to a gas-bubble pump 17 feeding into an expeller conduit 12. Expelled vapour flows through a pipe 20 into the horizontal part of the conduit 16 and is analyzed by the strong solution therein before flowing to the condenser through pipe 21. As shown in Fig. 2, strong solution flows from the heat-exchanger 13 through a bent expeller tube 23, 22 to a bubble pump 17 feeding into a conduit 25. Gas from the conduit 25 flows through a pipe 26 to a point in the conduit 23, 22 below the point of entry of the strong solution. This gas and the gas expelled in the part 22 are analyzed by bubbling through the strong solution in the part 23 before flowing to the condenser through a pipe 21. The flue tube 10 is split at 11 to prevent longitudinal heat conduction and the flue and the various conduits and the heat-exchanger may be embodied in a single heat insulated casing.

A water-soluble silicic acid powder contains at least one basic water-soluble salt of a trivalent and/or tetravalent metal, the powder being soluble in water to give a slica sol. The basic salt is a salt of Al, Ti or Zr, being present in the powder in an amount (calculated as metal oxide) of from 12-35% by weight based on the SiO 2  content. The powder may additionally contain 20-60% of a water-soluble solid hydrotropic substance which is not a salt and has a melting point of at least 30‹ C., e.g. urea, a substituted or cyclic urea, or a polyhydroxyl compound. A buffering mixture of acetic acid and sodium acetate may also be contained in the powder. The powder is prepared by mixing a colloidal silica sol with a solution of the basic metal salt to form a clear to opalescent solution which is then dried to give the powder. The hydrotropic substance may be added to the silica sol and the buffering mixture incorporated in the solution before drying. The solutions may be aged for 1 to 2 hours at elevated temperatures before drying.
