摘要:
A method of delivering a treatment substance to a target substance in a treatment zone is disclosed. The method comprises providing a treatment substance responsive to an electric or magnetic field such that the treatment substance experiences a kinetic force when disposed in said field, providing an electric or magnetic field extending through a treatment zone, and disposing the treatment substance in the electric or magnetic field such that the treatment substance moves towards the treatment zone and contributes to a reaction with the target substance. A corresponding system is also disclosed.

A device for sealing incisions in the body of a patient wherein the device includes a bioabsorbable sealing member having an elongate shaft member and an elastomeric and flexible balloon member. The device may also include a preformed or injectable collagenous material associated therewith to hemostatically seal the incision in the body of the patient. The shaft member may include one or more lumens extending therethrough in flow communication with one or more balloon members thereon to provide a relatively simple device which effectively seals an incision in the body of a patient.

The subject invention is directed to a floating platform for supporting nuclear reactors and the like at selected offshore sites. The platform is provided with a stabilizer mechanism which significantly reduces the effects of wave action upon the platform and which comprises a pair of relatively small floats attached by rigid booms to the platform at locations spaced therefrom for reducing wave pitch, acceleration, and the resonance period of the wave.

A cable gland assembly adapted to receive a cable and to pass through an opening in a sparking enclosure wall, the cable gland assembly including a cable-receiving gland, a stuffing box, a grommet, an insulator and a cable. The stuffing box has an opening there through, and a grommet-receiving portion having the grommet therein. The grommet-receiving portion is adjacent the cable-receiving gland. The stuffing box also includes a gas terminal portion filled with gas and adjacent the grommet-receiving portion, and an insulator portion having the insulator therein and being adjacent the gas terminal portion.

In one aspect of the present invention, an accessible indirect entry cable gland has a collar having a first end, an opposite, second end, and a first bore adapted for receiving a cable having one or more electrical conductors from the first end thereof and passing the cable through the second end thereof into a flameproof enclosure, a flame-resistant bushing filling a first part of the first bore of the collar at the second end thereof and adapted for passing the cable therethrough and holding the cable in place, and a cap having a first end and an opposite, second end, and a second bore adapted for receiving the cable from the first end thereof and passing the cable having one or more electrical conductors through the second end thereof into the collar. The accessible indirect entry cable gland further has an o-ring positioned adjacent to the first end of the cap and gripping a jacket of the cable, and a clamp adapted for mating with the first end of the cap so that the clamp and the cap can be fastened and re-fastened together after being un-fastened, wherein, when the clamp and the cap are fastened together, the clamp exerts a pressure on the o-ring against the jacket of the cable, thereby to retain the cable against movement with respect to the accessible indirect entry cable gland.
