Wissenschaft und Forschung. Studien über Kokskohle. V.F. Parry, leitender Ingenieur der Golden, Colorado Feldstation des US Bureau of Mines, "sichtet eine Koksblase". Dieses Verfahren wird angewandt, um festzustellen, ob ein bestimmter Koks seine Eigenschaften geändert hat oder ob er einem anderen Koks ähnelt. Ein Gramm Kohlenstaub wird zweieinhalb Minuten lang bei 820 Grad Celsius erhitzt. Die resultierende "Blase" wird dann mit einem Standarddiagramm verglichen, um ihre Charakteristika zu bestimmen, wie die Form zeigt, die sie angenommen hat. Diese Forschungen sind Teil eines Projekts zur Verbesserung der Qualität von Koks aus westlicher Kohle.

Method for preserving sweet cream indefinitely discovered by Government expert. Washington, D.C., Jan. 26. Dairymen the world over will benefit from a method discovered by Owen E. Williams, of the Bureau of Dairy Industry, U.S. Department of Agriculture, whereby sweet cream can be preserved indefinitely in sodium chloride, common table salt. To 100 pounds of cream testing 40 per cent butterfat, 7 pounds of salt are added. When the cream is to be delivered once a week from the farm to the creamery, enough salt is placed in the cream jar at the beginning of the week to preserve the week's supply. As more cream is added after each milking, it must be carefully mixed with the salt solution already in the jar. The salt prevents souring and acts as an anti-freeze. To remove the salt, Williams dilutes the thick cream with fresh skim milk and runs the mixture through an ordinary cream separator. The cream may then be used as coffee cream or it may be used in the manufacture of sweet cream butter or in the manufacture of ice cream. 1. Mr. Williams weighs out 7 pounds of sodium chloride - common table salt - which is sufficient to preserve 100 pounds of 40 per cent cream, 12639

Government discovers method to preserve film. Scratch resistance, film, particulary the emulsion side, may become damaged through scratching. D. Levinsky of the Bureau is using an instrument which tests the resitance of a film by measuring the width of a scratch produced by a diamond point under a given load. Another method is to put a piece of film in a bottle of sand, revolve the bottle a certain number of times, then measure the haxiness developed. Many commercial treatments designed to increase the hardness of the emulsion have been investigated, 7838
