Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. Low-velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate.
A heat gun is a device used to emit a stream of hot air, usually at temperatures between 100 and 550 °C (373 and 823 K; 212 and 1,022 °F), with some hotter models running around 760 °C (1,030 K; 1,400 °F), which can be held by hand. Heat guns usually have the form of an elongated body pointing at what is to be heated, with a handle fixed to ...
The most common use for differential tempering was for heat treating cutting tools, such as axes and chisels, where an extremely hard edge is desired, but some malleability and springiness is needed in the rest of the tool. A chisel with a very hard edge can maintain that edge longer and cut harder materials, but, if the entire chisel was too ...
The origins of the Bauer brand of hockey equipment trace to 14 September 1906, when the Western Shoe Company Limited was formed in Kitchener, Ontario. At an unknown date, Roy Charles Bauer (1895–1989) became president of the company. On 5 May 1934, Bauer formed a new company, the Canada Skate Manufacturing Company Limited, to produce ice skates.
Ventilation is a part of structural firefighting tactics, and involves the expulsion of heat and smoke from a burning building, permitting the firefighters to more easily and safely find trapped individuals and attack the fire. It is frequently performed from the outside of a burning building while the fire is being extinguished on the inside.
The heating oil futures contract trades in units of 1,000 barrels (160 m 3) with a minimum fluctuation of $0.0001 per gallon and (for the USA) is based on delivery in New York Harbor. [5] The Department of Energy tracks the prices homeowners pay for home heating fuel (oil and propane).
There are also methods of cold bluing, which do not require heat. Commercial products are widely sold in small bottles for cold bluing firearms, and these products are primarily used by individual gun owners for implementing small touch-ups to a gun's finish, to prevent a small scratch from becoming a major source of rust on a gun over time.
