    Abstract: A process for the preparation of organic compounds or polymers containing one or more sulphur atoms and including one or more double bonds in a hydrocarbon chain is described. An acyclic sulphur-containing olefin or an unsaturated sulphur-containing cyclic hydrocarbon undergoes a self metathesis reaction or a cross metathesis reaction with a non-sulphur-containing acyclic olefin or a non-sulphur-containing unsaturated cyclic hydrocarbon to produce novel olefins, novel dienes, and/or olefinic polymers containing one or more sulphur atoms.

    Abstract: A magazine-indexing mechanism for a powder-actuated tool, of the type adopted for use with a disk-shaped cartridge magazine, is actuated by the same trigger displacement as actuates the firing mechanism. A first link, pinned to the receiver, and a second link, pinned to an extension of the trigger, are pinned together, with a magazine engaging hook disposed on the dictal end of the first link. When the trigger is pulled, as to fire the tool, the hook is displaced to engagement with the magazine. When the trigger is released, the engaged hook is displaced, indexing the magazine. Means are also provided to prevent indexing an unfired cartridge through the tool.

    Abstract: A power adjustment for a piston-type powder actuated fastener driving tool wherein a tube is slidably disposed in the barrel of the tool, the tube containing the driving piston of the tool. The tube has a radially inwardly extending flange at its breech end which engages a radially outwardly extending surface on the piston. Means for moving the tube axially of the barrel are provided so that the distance between the flange and firing chamber can be varied whereby the gas expansion chamber between the firing chamber and the rear face of the piston can be varied thereby varying the power with which the piston is driven.
