Peracetic acid and perpronionic acid are useful in the treatment of growing plants in order to control the growth of adventitious organisms. They are especially effective in controlling the growth of fungi and microbial plant pathogens. The acids are especially useful in the treatment of edible crops since they do not leave a toxic residue on the surface of the plant.
摘要:
Corrosion-resistance in a brazed aluminium product is improved by subjecting the product to a heat treatment at a temperature of 300° to 800°F (150° to 425°C) for at least 25 minutes, preferably preceded by cooling the product to a temperature below the temperature ultimately selected for the treatment and in any event below about 550°F (290°C).

A therapeutic composition for veterinary use comprises a therapeutic agent, such as an anthelmintic drug, associated by sorption and/or adsorption with a substrate selected from zeolites and/or pillared clays. Preferably, the drug is present in an amount in the range from 5 to 300 mg per gram of substrate.
摘要:
A two-wheeled drum truck slidably mounts a drum flange or chime (C) clamp (60, 61) which is powered from an energy source on the truck to raise the drum (D) for depositing the same on a pallet (P) or the like. An electric motor (40) driven linear actuator (43) on the truck is energized from a batter (B) also carried on the truck to drive the clamp. A double pole switch (80) on or adjacent the handlebar (13) of the truck controls a circuit to drive the motor in either of two opposite directions. The clamp automatically locks the drum to the truck when raised against the chime ring of a barrel or drum. Rollers (19) on the truck embrace and cradle the drum, so that it is easily raised and lowered on the truck.
摘要:
A combination two-section boat and cargo carrier comprises first and second substantially identical sections (10, 12), each having a substantially horizontal bottom surface (14), at least two generally vertical sidewalls (16, 18) and a generally vertical connecting wall (22). The connecting wall is configured with a male connector (62a, 62b), which protrudes from the surface of the connecting wall in a direction generally normal to the plane of the connecting wall, and a complementary female connector (64a, 64b) which is recessed into the connecting wall in a direction generally normal to the plane of the connecting wall. The male and female connectors are symmetrically disposed from a vertical centre line of the connecting wall and are adapted to mate with each other when the connecting walls of the first and second identical sections are placed in abutting relation to one another. A removable assembly blade connector (68) is provided in order to join the male and female connectors, so as to form a boat. When superposed, the sections provide a water-tight cargo carrier which is secured by removable clamps (38) which engage the upper protruding edges of the sections.
摘要:
A silage additive comprising molasses and vinegar also includes at least one bacterial inoculant, preferably present in micro-encapsulated form. A very effective form of additive contains at least two types of bacterial inoculant and, also, at least one enzyme, such as invertase.

A transdermal delivery system for a vasoactive substance includes, by weight, about 30 to 70% of a medically-acceptable liquid silicone rubber, about 5 to 25% of a vasoactive substance, about 0.1 to 2.0% of a gelling agent, about 2 to 15% of a material which swells as water is absorbed from the stratum corneum and about 5 to 35% of a mixture comprising one or more solvents, viscosity reducers and skin penetration enhancers including, by weight of the entire delivery system, about 5 to 25% of a solvent, about 0 to 5% of a viscosity reducer and about 5 to 25% of a skin penetration enhancer.
