Abstract: An aseptic valve assembly (10) is provided for filling and discharging containers. A valve fitting (11) is fixably attached in a bottom wall (19) of a container (20). A plug (12) may be secured within the container fitting (11). A sterilization/fill unit (14) is removably attached to the container fitting (11) so that the container (20), the plug (12) and the container fitting (11) may be sterilized and the container (20) filled and sealed under aseptic conditions.

Abstract: An elastomeric spring is formed by extruding a rubbery material into a reinforcing sleeve in a mold during relative motion between the mold and nozzle, and thereafter vulcanizing.

Abstract: The invention herein is directed toward a process of preparing free flowing thermoset resin particles of polybutadiene and includes the steps of physically mixing a filler material with polybutadiene followed by chopping the mixture into small particles or granules which are irregularly shaped. A vulcanizing agent can be added during the mixing step as well as other ingredients commonly added to polybutadiene resin formulations, as is customarily done in the art, without affecting the free flowing properties of the polybutadiene treated according to the process of this invention.

Abstract: High vinyl polybutadiene having an increased cure rate and superior properties comprises a peroxide curing agent selected from the class consisting of dicumyl peroxide, t-butyl perbenzoate, bis(t-butylperoxy) diisopropyl benzene, and n-butyl 4,4-bis(t-butylperoxy) valerate in combination with a peroxide selected from the class consisting of benzoyl peroxide, bis(4-t-butylcyclohexyl) peroxydicarbonate, t-butyl peroctoate, 2,5-dimethyl-2,5-bis(t-butylperoxy)-hexane, 2,5-dimethyl-2,5-bis(t-butylperoxy)-hexyne-3, and t-butyl hydroperoxide.
