Abstract: Overbased detergent additives for lubricating oils comprise an organic substantially aromatic carboxylate, such as an alkylsalicylate, as a surfactant and have a TBN of 200 or greater, an active ingredient content of 70 mass % or greater, a kinematic viscosity at 100° C. of less than 1000 mm2s−1 and a basicity index (BI) of less than 13.

Abstract: A conveyor module adapted to receive products thereon for translating and simultaneously rotating the product 90° in going from its infeed end to its outfeed end. An endless chain is deployed about spaced-apart sprocket wheels, one at the infeed end and one at the outfeed end and a plurality of product support plates are linked to the chain by a coupler that permits rotation of the support plate about an axis that is perpendicular to the support plate. The support plate carries a cam follower that is adapted to engage a cam track that is configured to impart the 90° rotation to the support plate as the endless chain carries the support plate between the infeed end and the outfeed end.

Abstract: The invention concerns high-stability oils comprising vegetable, non-lauric triglycerides that are liquid above 10.degree. C. and that display RIP values at 120.degree. C. of at least 35 hours.The N-profile of the oils displays the following characteristics: N.sub.15 <10; N.sub.10 <15 and N.sub.0 <20.
