Abstract: A dual purpose animal collar is described where the collar consists of a single length of material having the ends thereof provided with a connector for releasably coupling them together to form a continuous ring. The coupling is releasably disconnectable upon reaching a predetermined pressure. Each end of the collar assembly is provided with a ring member attached thereto within one ring sized to pass through the other so that the collar can be used in the normal way of a collar by a snap ring holding the two rings fixed to one another and in such a manner as to prevent release of the collar under the predetermined pressure, as a safety collar and as a choke collar.

Abstract: A process for preserving canned, low-acid foods comprising the steps of adding diacetyl, which may be in the form of a starter distillate, to food and heating the canned food to render the food commercially sterile. The diacetyl lowers the temperature required for processing and remains in the food product at a level sufficient to kill germinating bacterial spores.
