The stock further includes an elongated lower second forestock element spatially separated below the stock for at least part ...

An process for working a material in which a reverse thermal fluid is used as a cutting fluid and, as a result of heat generated during the working process, the fluid increases in temperature above its transition temperature and viscosifies and thickens. In another embodiment, the invention is an article of manufacture of a material which has been worked to increase its temperature and a reverse thermal fluid in intimate thermal contact with the material above the transition temperature of the r...

Compositions are provided which are aliphatic sulfurized esters of olefinic mono- or dicarboxylic acids which do not contain any allylic hydrogen atoms. Synergistic mixtures of esters sulfurized with sulfur and with sulfur monochloride and sulfur dichloride are provided. Also provided are lubricating oil compositions comprising (A) a major amount of an oil of lubricating viscosity, and (B) an amount effective to impart extreme-pressure and/or antiwear lubricating properties to said oil of these ...

A survival weapon is described in which a projectile firing weapon mounts a stock member. A connector mounts the stock member to the projectile firing weapon for selective motion between an inoperative position in which the stock member is positioned in juxtaposition to the projectile firing weapon, and an operative position in which the stock member projects outwardly of the projectile firing weapon. The stock member includes compartments releasably receiving survival items such as a fire start...
