The practice of billeting evacuees was widespread in Britain during World War II, particularly during the Blitz, when children and other non-essential persons in major cities were sent to rural areas for safety. During wartime, civilians who have been evacuated from a city in danger of attack are billetted in communal shelters or in the homes of individuals. Repeated petitions against the practice of billeting, starting in the 16th century, culminated in its outlawing in 1689 as an extension of a section of the Petition of Right 1628. From this meaning, the word billet came to be loosely used of the quarters thus obtained. Originally, a “billet” (from the French) was a note, commonly used in the 18th and early 19th centuries as a “billet of invitation.” A particular use of the word in this sense is to denote an order issued to a soldier entitling him to quarters with a certain person. There are many types of rolling processes, including flat rolling, foil rolling, ring rolling, roll bending, roll forming, profile rolling, and controlled rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process and cold rolling processes the most tonnage out of all cold working processes. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. Rolling is classified according to the temperature of the metal rolled. In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls.
