Abstract: There are described delivery devices for insertion into a body cavity of a target mammal, the delivery device comprising a resilient frame adapted to receive one or more moulded impregnated masses. The frame, together with the impregnated mass, are insertable, retainable and withdrawable from the intended body cavity. The impregnated mass or masses are attached to the frame to present substantially all of each face of the masses to exposure to a fluid of the body cavity when retained therein.

Abstract: The present invention relates to a device for administration to the mammary gland cavity of a subject including at least one active agent; and, at least one carrier material; and, characterized in that the environment into which the device is inserted into activates dispersion of the active agent. In further embodiments, a muco-adhesive material is used as a retainer material for the carrier material/active agent mixture. The aim of the device is to deliver active agent or agents to a subject in the form of a suppository that, on administration to the subject, disperses into the subject environment. The device is particularly useful for delivery of an active agent to the mammary gland of a lactating cow.

Abstract: The present invention relates to a formulation for parenteral consisting of a gelling agent or agents, a water miscible solvents and an active agent or agents. The aim of the suspension is to deliver active agent or agents to a subject in the form of a depot that, on administration to the subject, forms a depot. The depot will disperse in time and during this time period, active agent or agents are released into the subject.

Abstract: A machine for continuously making gaskets and similar flat products. Sheet gasket material is fed from a roll and through tooling that successively: cuts the outline, separates the center scrap, then separates the gaskets from the remaining sheet stock waste. The cutting tool rotates. The center scrap and the gaskets may be removed by rotating tooling or by vacuum and air pressure, respectively. Design and fabrication of such a machine, especially the cutting roller, is made possible by state of the art CAD software.
