IPC: C07D207/12
Filed: 1990-10-11
Abstract: HA489 Abstract PROCESS FOR DIRECT ISOLATION OF CAPTOPRIL A process is disclosed for direct isolation of captopril from a substrate of the formula wherein R is lower alkyl or lower alkoxy. In this process, the substrate is first treated with an aqueous alkali metal hydroxide capable of forming a water-soluble salt of the substrate, wherein the alkali metal hydroxide has a concentration of 4 M or greater. The substrate is then neutralized, preferably with a mineral acid. By this process, captopril may be directly crystallized from an aqueous solution, avoiding the prior art use of organic solvents and zinc treatment to reduce levels of sulfide and disulfide impurities, respectively. In an alternative embodiment, neutralization is carried out by use of a hydrogen-supplying ion exchange resin.

Title: Seeder clutch for tramlines
Inventor: LAFFERTY JAMES G
IPC: A01C7/08
Filed: 1990-11-19
Abstract: A clutching mechanism for a seed meter incorporates a spring wrapped clutch for selectively disengaging a seed meter on a seed drill in order to tramline fields for agricultural purposes. A common shaft rotates and dispenses seeds from a series of seed meters on the drill. The spring wrapped clutch of the present invention allows for disengagement of singular meters from the rotational actuation of the common shaft. The seed metering incorporates a rotatable drum which dispenses the seed as it is turned. The drum is attached to a driven element which is further attached to a spring. The spring compressibly holds a driving element attached to the rotatable shaft. A selective engagement of the spring causes a decompression on the driving element and consequently, stops the rotation of the seed drum within the seed meter.
