    摘要: A transdermal drug-containing dosage unit comprises: a backing layer substantially impervious to the drug to be delivered transdermally; a first polymeric adhesive matrix, in contact with the backing layer, having dispersed therein the drug and having a first delivery profile of the drug; a second polymeric adhesive matrix, in contact with said first polymeric adhesive matrix, having dispersed therein the drug and having a second delivery profile of the drug, wherein said second delivery profile is different from said first delivery profile; and a release liner in contact with the second polymeric adhesive matrix. The first polymeric adhesive matrix can release the drug more quickly or more slowly than the second polymeric adhesive matrix. Through the selection of the two matrices, the delivery profile of the drug through the skin can be selectively modified and controlled.

    摘要: An apparatus (40) and method for increasing the fin density of a serpentine sheet (10) having a plurality of fins (14a, 14b, 14c), each fin having two sides (16, 18) coupled together at one end (20) with a space (22) between the sides. Blocks (30, 32) having receptacles (30a, 32a) for receiving the ends (20, 24) of one side (16) of a fin (14a) and being near opposite surfaces (A, B) of the sheet (10) are moved vertically into contact with such ends. Simultaneously, blades (34, 36), being near the opposite surfaces (A, B) of the sheet (10) are moved vertically into position at the other side (18) of the fin (14a). Then, the blades (34, 36) are moved horizontally towards the blocks (30, 32), which are now held stationary, to compress the fin (14a) a predetermined amount by moving the other fin side towards the one fin side. The blocks and blades are then withdrawn from the sheet to move another fin (14b) into position for another compressing operation. The apparatus (40) includes a mechanism (70) to prevent the sheet from fishtailing when a fin is being compressed.

    摘要: Pyritic sulfur is removed from coal or other carbonaceous material through the use of humic acid as a coal flotation depressant. Following the removal of coarse pyrite, the carbonaceous material is blended with humic acid, a pyrite flotation collector and a frothing agent within a flotation cell to selectively float pyritic sulfur leaving clean coal as an underflow.

    摘要: A fiber optic cable is coupled with an electro-optic transducer through a ferrule which terminates the cable that is inserted in a passageway of a housing which is mounted on a planar surface so that the passageway is transverse thereto. A cover placed over the housing and latched thereto isolates the ferrule from dust and external light and insures its proper alignment with the electro-optic element, which is inserted in the passageway from the opposite end via an opening in the planar surface, by exerting a spring force on a flange of the ferrule which is a greater distance from the end of the ferrule than the distance between the passageway entrance to the ferrule and the electro-optic transducer when positioned in the passageway so that the fiber optic cable and transducer abut one another upon placement in the passageway to effect an efficacious coupling.
