Abstract: A chain lubrication application tool is provided, the tool having an L-shaped body and a swivel fitting attached to the body. The L-shaped body has a top member and a side member, the top member and side member forming the L-shaped body. The swivel fitting is attached to the top member of the L-shaped body and has an inlet operable to accept lubrication from a lubricant dispensing container and an outlet to supply the lubrication to a drive chain that can be located below the top member of the L-shaped body.

Abstract: A method of dimerizing alpha-olefins to mostly linear internal olefin dimers using as a catalyst a transition metal complex with an activating co-catalyst.

Abstract: A return mailer bearing computer readable information including a mailing panel of a first surface porosity, adapted to bear an address of a returnee, further including a folding sealing flap along one transverse edge that is adapted to form a transverse edge of the envelope when it is folded and sealed. Also included is an information panel of a second surface porosity, bearing machine readable information on at least one side, which includes two transverse perforations, wherein the perforations are separated by a longitudinal distance sufficient to span the portions of each side of the information panel bearing information of interest to the returnee. The two panels are joined by an adhesive along the two longitudinal segments of their periphery to form the two longitudinal edges of the envelope. The adhesive maintains the mailer in sealed condition during mailing, while not contributing to gnarling or tearing of either panel upon separating the two panels upon opening.
