The present invention has several plausible embodiments. In one embodiment an apparatus for coating a medical device is provided. This apparatus includes a coating chamber, a vibrating structure within the coating chamber the vibrating structure capable of suspending a medical device positioned in the coating chamber, and a coating source, the coating source positioned to introduce coating into the coating chamber. In another embodiment a method of coating a medical device is provided. This method includes moving a medical device into a predetermined coating area, vibrating a structure below the medical device, the vibration of the structure forcing the medical device away from the vibrating structure, and coating at least a portion of the medical device that has moved away from the vibrating structure.

Mechanical and acoustical suspension coating of medical implants

Briefly stated a tag includes a dielectric substrate having first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap which establishes an electrical open circuit. An electrically conductive composition including electro-conductive particles is provided for bridging the gap in the conductive pattern to temporarily establish an electrical closed circuit which resonates when exposed to electromagnetic energy at a frequency within a predetermined frequency range.

Resonant tag with a conductive composition closing an electrical circuit

A resonant tag circuit useful as an electronic security device includes a layered planar structure having a dielectric substrate, a resonant circuit carried on both sides of the dielectric substrate and a semiconductive material having an ionizable salt dissolved therein. The semiconductor material provides a sermiconductive bridge across an activation or deactivation point in the circuit and connects the conductive circuit on both sides of the activation or deactivation point. The resonant tag circuit of this invention is stabilized against premature operation of the activation or deactivation point from electrostatic discharge.

The use of selected metribuzin analogs to control crystallization of metribuzin in mixtures of metribuzin and aromatic hydrocarbon-based grass killing herbicides is disclosed.

Herbicidal spray mixtures

N-Methylol derivatives of herbicidal 4-amino-1,2,4-triazine-5-ones can be prepared by reacting formaldehyde with a 4-amino-1,2,4-triazine-5-one slurried in water under basic conditions. The N-methylol derivatives can be surface-modified by slurrying particles of the derivatives in water and treating with a strong acid or strong base, producing a product that releases the original herbicidal 4-amino-1,2,4-triazine-5-one in a controlled manner.

Controlled release granules of methyl 2-(dimethylamino)-N-[[(methylamino)carbonyl]oxy]-2-oxo-ethanimidothioate, oxamyl, are effective soil insecticides and nematicides, and are especially useful for the prolonged control of root knot nematodes.

Controlled release granules

The instant invention relates to a process for preparing novel insecticide-polymer particles. The process consists essentially of dissolving the insecticide, methomyl, and a polymer in a solvent in which both are soluble. The solution is then comingled with a non-solvent for both the polymer and the methomyl under high shear conditions. A particulate product is formed consisting of irregularly shaped particles having methomyl embedded in a polymer matrix. The irregularly shaped particles may be dispersed, e.g. in water, and sprayed readily into an area of insect infestation.
