Abstract:
A new series of 2-pyrazinemethanols useful for the protection of plants from microbial diseases has been discovered. The new compounds are characterized by alkyl, cycloalkyl or phenyl substituents on the Alpha -carbon and by a single additional substituent on the pyrazine ring. Many of the compounds are additionally useful for the inhibition of plant growth.

Abstract:
An ester of a 7-acylamido-3-fluoro-3-cephem-4-carboxylic acid is prepared by reacting a 3-sulfonate ester of an ester of a 7acylamido-3-hydroxy-3-cephem-4-carboxylic acid in an inert solvent with an inorganic fluoride in the presence of an 18crown-6 ether and at a temperature of from about -20* C. to about +25* C.
Abstract:
3-Halomethyl- Delta 3-cephalosporin (sulfide) esters and sulfoxides thereof, prepared by reacting a phosphorus halide with a 3-hydroxymethyl- Delta 3-cephalosporin sulfoxide ester, which sulfide esters can be de-esterified to form antibiotics, and which sulfide ester and sulfoxide ester products are useful as intermediates in the production of known and new antibiotics.

Abstract:
Randomly oriented medicinal capsules are processed to a uniform cap-forward orientation at high handling rates. The capsules are conveyed endwise in a series of deep conveyor cavities, each with an upper portion to loosely contain the capsule, with shoulders at the bottom of such portion defining a rectification slot of a width to pass a capsule body but retain its cap, and deep enough below the shoulders to substantially contain the body of an upstanding capsule supported at its cap edge by the shoulders. The conveyor slopes upward and is centrally slotted to straddle a thin cam rail which supports capsules lengthwise in the upper portions of the cavities. In a rectification zone, the cam rail rises to lift the capsules well away from the side shoulders, and then terminates abruptly above a suction passage which draws air downward through the conveyor cavities. As a body-forward capsule crosses the rail terminus, its rear end is supported by the rail and its forward end is unsupported in the downward air stream. This tips it forward about the rail terminus and its body passes through the slot. Its cap edge is carried into engagement with the side shoulders with sufficient momentum and at an angular orientation which causes the cap edges to wedge slightly between the side shoulders to form two side points of engagement about which further tilting tends to occur and which resists sliding of the capsule lengthwise of the cavity shoulders. The tilting carries the capsule to a forward-leaning position, and the capsule then engages an underlying secondary cam rail which rises to lift the lower end of the capsule. Such lifting, combined with continuing downward air flow, moves the capsule to a cap-forward position in the cavity. Any capsule which may slip rearward in its cavity is contained by the deep walls, and is lifted by the secondary cam without danger of being pinched or caught. Capsules originally in cap-forward position are not changed, since their forward caps will be supported by the cavity shoulders as the capsules cross the rectification zone.
Abstract:
A compound of the formula PyroGlu-Trp-Ser-Tyr-D-Ala-Leu-Arg-ProNHCH2CH3 as well as its pharmaceutically acceptable acid addition salts exhibit inhibiting action toward luteinizing hormone release hormone (LH-RH) and are potent contraceptives.
