Abstract: 534,616. Explosives. HEPBURN, J. T. BUCHAN-. July 8, 1939, No. 19981. [Class 9 (ii)] An explosive composition is produced by incorporating an explosive substance in a dispersion of rubber or analogous vulcanizable substance, and in vulcanizing the product. In an example, a vulcanizable latex is produced by mixing colliodal sulphur, zinc diethyldithiocarbamate and zinc oxide with a 5 per cent solution of casein, and adding the cream thus obtained to rubber latex. The explosive substance, for example, nitro-glycerine or potassium nitrate is mixed with the latex and the mixture vulcanized. Instead of rubber latex, artificial dispersions of natural rubber, or dispersions of  vulcanizable artificial rubber, or of allied substances such as gutta percha and balata, may be used.

Title: Improvements relating to the heat treatment of liquids
IPC: A23L3/10
Filed: 1947-07-25
Abstract: In a process wherein a batch of filled, capped bottles of liquid such as milk, cream, or beer is heated by immersion in a tank of hot liquid and then cooled by immersion in a tank of cold liquid, there is employed for the heating tank and for the cooling tank a time-temperature recorder the temperature-sensitive element of which is located so that it is immersed in the heating liquid or in the cooling liquid when the batch is immersed, and is uncovered when the batch is removed.  The abrupt change of temperature thus recorded upon immersion and upon removal of the batch from the heating liquid or from the cooling liquid may be increased by causing cold or warm water to drip upon the temperature-sensitive element when it is uncovered. Specification 604,324 is referred to.
