Abstract:
The present invention relates to a conveying system such as in an assembly line, more particularly to a plurality of transport cars without motor that are driven in close contact with each other on an endless path on guide rails having curved sections, and a friction feeder for moving the transport cars. The cars have a main body and a support for objects to be conveyed. The main body has a plurality of movable bodies and means for coupling the movable bodies to allow a relative yielding motion between the movable bodies at the curved sections in the conveying paths. Driven faces are formed on the movable bodies parallel to the running direction, and a feeder along the conveying path and having a motor driven feed roller that acts on the driven faces of the movable bodies.
Abstract:
Derivatives of ML-236B carboxylic acid, its salts and esters and corresponding lactone have a hydroxy group at the 3"-position and optionally also at the 6'-position. These derivatives may be prepared by the enzymatic hydroxylation of a corresponding ML-236B compound employing an enzyme produced by a microorganism of the genus Streptomyces or Amycolata, especially Streptomyces sp. SANK 62285, Streptomyces sp. SANK 62385, Streptomyces sp. SANK 62485, Streptomyces sp. SANK 62585, Amycolata autotrophica SANK 62781. Amycolata autotrophica subsp. canberrica SANK 62882 or Amycolata autotrophica subsp. amethystina SANK 62981. These derivatives have the ability to inhibit cholesterol biosynthesis.
