Abstract:
A manually manipulatable spray mechanism for connection to a supply apparatus having a source of molten asphalt under pressure for applying a sprayed coating of molten asphalt on selected areas of a paved surface. The spray mechanism is configured so that its asphalt spray pattern may be adjusted to suit the job being accomplished, and, to provide for recirculatingly returning the molten asphalt to the supply apparatus when the spray mechanism is in the inoperative or stand by state.
Abstract:
A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.
Abstract:
Provided is a method for preparing a true, homogeneous solution of a pharmaceutical substance dissolved in an organic solvent in which the pharmaceutical substance is not normally soluble. Solubilization is obtained by forming a hydrophobic ion pair complex involving the pharmaceutical substance and an amphiphilic material. The resulting organic solution may be further processed to prepare pharmaceutical powders. A biodegradable polymer may be co-dissolved with the pharmaceutical substance and the amphiphilic material and may be incorporated into a pharmaceutical powder. A preferred method for preparing pharmaceutical powders is to subject the organic solution to gas antisolvent precipitation using a supercritical gas antisolvent such as carbon dioxide. Also provided is a method for making hollow particles having a fiber-like shape which would provide enhanced retention time in the stomach if ingested by a human or animal host.

Abstract:
The present disclosure includes a method of making an improved carbetocin drug product. The disclosed method for making an improved carbetocin drug product comprises agitating a carbetocin preparation containing an aqueous solution of carbetocin and one or more excipients for a period of time to initiate the formation of aggregate-forming solids and filtering off the aggregates that form before further processing the remaining carbetocin into a final drug product. The present disclosure also relates to an improved carbetocin drug product, wherein the drug product is substantially free of aggregate-forming solids. The disclosed carbetocin drug product can be used for the treatment of a neurodevelopmental disorder, such as Präder-Willi syndrome. Additionally, the disclosed carbetocin drug product shows content uniformity of carbetocin over long periods of time before and after one or more freeze/thaw cycles, provides enhanced convenience and patient compliance, and/or are highly concentrated.
Abstract:
An expendable underwater vehicle for use in training naval forces in anti-submarine warfare in ocean waters, including shallow waters, is between about three to five feet in length and about five inches in diameter, and it includes various improvements which make successful operations in shallow ocean waters, and improved operation in all ocean waters, possible. The improvements include a one-piece nose cup which allows the expendable underwater vehicle to be air launched into shallow water, a scuttle plug which allows water to fill the expendable underwater vehicle after the vehicle is expended and drops to the bottom of the ocean, and rudders and elevators of increased surface area which improve controllability of the vehicle in the water.
Abstract:
An expendable underwater vehicle for use in training naval forces in anti-submarine warfare in ocean waters is between about three to five feet in length and about five inches in diameter, and it includes various improvements which make successful operation in the ocean waters possible. The improvements include an in-water variable speed feature, a variable tonal levels feature, an autonomous evasion feature, and a high-power integrated pinger feature. One or more of these features can be combined to provide an extremely effective and versatile expendable underwater training vehicle.
