Patent GB-872610-A (GB)
Title: Gas plating of aggregates
Inventor: MARVIN PHILIP R
IPC: C23C16/04
Filed: 1958-03-07
Abstract: The interior of an aggregate body is metallized by permeating the interstices of the body with a heat-decomposable metal-bearing compound while the interior of the body is at a temperature at least equal to the decomposition point of the metal-bearing compound and the exterior of the body is at a temperature below this point.  Thus the interstices of compacted bodies made from such materials as powdered metals, silicides, carbides (e.g. silicon carbide or aluminium carbide), emery and corundum, may be filled with metal by the decomposition of e.g. the carbonyls of nickel, iron, chromium, molybdenum and tungsten, copper acetylacetonate, (C2H5)3PAuCl and (C4H9)3PAuCl.  As described, the aggregate body is first heated to above the decomposition point of a metal-bearing compound, cold gas is then allowed to sweep over the body to reduce the temperature of the exterior of the body to below said decomposition point, and the body is finally permeated with the metal-bearing compound.

Title: Improvements relating to the Brewing of Beer.
Inventor: BOULARD HENRI
Filed: 1918-05-07
Abstract: 119,833. Boulard, H. May 7, 1918. Fermenting; wort, producing.--To dispense with malt, the wort is saccharificed by means of a mucor, such as the mucor Boulard No. 5 described in Specification 25406/13, the hops being added before saccharification. The grain is first boiled under pressure, organic acids being added if necessary, to break up the grain and transform the starch into soluble starch and dextrin. The pressures employed and the time of boiling depend on the kind of beer which it is desired to produce. Tartaric acid is stated to give the best results, acetic acid coming next. Hops are then added, preferably in two or more stages, and boiling continued to " break " and sterilize the wort. The wort is then transferred to another vat and cooled to 38 or 40‹ C., and the saccharifying mucor is introduced. The wort is then rapidly cooled to precipitate nitrogenous matters, having been previously boiled if necessary. The mucor may be introduced as a " bacteriological culture," or may be cultivated in a vat from a quarter to a tenth the size of the saccharifying vat. Fermentation may take place in the saccharifying vat or in a separate vat as desired.
