Abstract: A flexpin assembly (B) for an epicyclic gear system (A) includes a flexpin (20) that at one end is cantilevered from a carrier end wall (12) and a sleeve (22) that surrounds the flexpin and is cantilevered from the flexpin at the other end of the flexpin. In addition, the assembly has an antifriction bearing (24) for supporting a planet pinion (6) around the sleeve. The flexpin has a base (30) that is configured to be anchored to a carrier wall, a head (32) to which the sleeve is attached, and a shank (34) located between the base and head. The sleeve has a mounting segment (78) that is connected to the head of the flexpin without a weld. Both may have tapered surfaces secured in contact by a plate (66) clamped against the mounting portion with screws (68) that thread into the head, thus enabling the sleeve to be detached from the pin. The head may have a cylindrical surface (72) over which the mounting segment of the sleeve fits with an interference fit exists.

Abstract: Biocidal preservatives for use especially in preventing rotting and deterioration of wood include quaternary ammonium compounds which preferably have a fatty aliphatic substituent on the quaternary nitrogen atom. Especially preferred are cocoalkyl substituents. Other substituents can include alkoxy groups, arenes, and heterocyclic groups with or without ring substitutions, for example. The quaternary ammonium compound can also contain an amine nitrogen and can be complexed with copper.

Abstract: The invention relates to a brace which is mountable in or on, or is formed integral with, a craft such as a canoe, kayak, surf-ski or skiff so that it can in use contact and receive thrust from the thigh of a user of the craft so that the user can propel the craft more easily and can prevent himself from falling from the craft.
