Abstract: A lock nut assembly comprises a sleeve bolt (1), a clamp bolt (6) and a locking bolt (7). The sleeve bolt (1) has a hollow shank with an internally threaded portion (5) at one end and a head (3) having an axial bore (2) extending through it at the other end, at which it is internally threaded (4). The clamp bolt (6) also has a hollow shank with an externally threaded central portion (9) and an internally threaded portion (10) at one end (10) and a head (8) at its opposite end. The locking bolt (7) has an externally threaded portion at one end (12) and a head (11) at its opposite end. The central portion (9) of the clamp bolt (6) and the internally threaded portion (5) of the sleeve bolt (1) are dimensioned for co-operation with threads of one hand, and the second portion (10) of the clamp bolt (6) and the externally threaded portion (12) of the locking bolt (7) are dimensioned for co-operation with threads of opposite hand.

Abstract: A lubricating composition having improved resistance to removal by water, improved pumpability over a wide range of ambient temperatures, and the ability to float on water comprising a petroleum base oil thickened with a lithium soap of a fatty acid and containing a polyisobutylene of a molecular weight to provide such properties.

Abstract: Saturated and/or unsaturated monohydric alcohols are added to allylic halides in the presence of copper (I) halide and a solid organic-insoluble acid acceptor such as MgO to form ethers in which at least one and preferably both of the organic groups attached to the ether oxygen atom contains a single carbon-to-carbon double bond.

Abstract: A process for preparing a catalyst which involves coating a support with a platinum or palladium salt, calcining, further coating the calcined support with a solution containing a ruthenium or rhodium salt and an oxide, salt or acid of phosphorus and then further calcining.
