Abstract: An apparatus for filling a syringe by transferring a viscous material from a container into the syringe includes a container having an interior that holds the viscous material and a plunger that expels the viscous material from the container. A syringe is connected to the container for receiving the viscous material at an entrance opening. The syringe includes a plug that separates the syringe into first and second sub-chambers and a rod contacting the plug and applying a force in the direction of the entrance opening. An assisting device assists in moving the rod away from the entrance opening as the first subchamber fills with the viscous material.

Abstract: A cap filled with fluid sealant is produced for subsequent attachment to an exposed portion of a fastener, such as a bolt head. The cap has a shell made of a synthetic resin formed in a generally hemispherical, hollow shape, and a recess defined by an inner surface of the shell in a generally hemispherical shape. The method includes filling the recess with a fluid sealant, which contains a mixture of a thermosetting substance and a curing agent that is freezable prior to curing, such that while the sealant is frozen, no curing takes place, and when the sealant is subsequently heated and thawed, its original fluidity is restored and curing of the thermosetting substance restarts. The sealant is then frozen while the sealant is filled in the cap. Subsequently the sealant is thawed and any condensation that forms on the sealant or the cap during the thawing is removed by drying.

Abstract: Molding methods and molds for making a synthetic resin molded product include disposing a curable liquid resin mixture in a recess of a female mold. The curable liquid resin mixture is then simultaneously agitated and degassed by a mixer while under a partial vacuum. More specifically, at least the female mold is orbited around an orbital axis while being rotated about a rotational axis that is eccentric to the orbital axis. After being thoroughly mixed and degassed, the liquid mixture is then cured in the mold unit.

Abstract: A method and apparatus are disclosed for transferring and filling a viscous material from a container into a syringe while preventing the ingress of gas into the viscous material during the process of filling the syringe with the viscous material, but without requiring a housing for holding both the container and the syringe in an air-tight manner. The method includes inserting a plunger into the container that holds the viscous material and inserting a first plug, which permits gas flow in one direction, into the syringe. Then, the container is coupled to the syringe, a rod is inserted into the syringe such that the rod engages with the first plug, and the plunger is pushed within the container, thereby extruding the viscous material from the container. As a result, the extruded viscous material is transferred into the syringe and the syringe is filled with the viscous material.

Abstract: A plunger is fittable within a cylinder of a pneumatic dispenser that discharges a viscous material. The plunger has a first portion located at the front, and a second portion located at the rear. The second portion is a hollow structure and has a circumferential wall. An inner circumferential surface of this circumferential wall has a tapered surface. The circumferential wall has a thickness dimension that decreases in the axial direction moving away from the first portion. Therefore, the circumferential wall easily displaces in the radial direction, because the bending stiffness decreases in the axial direction moving away from the first portion. The first portion is a solid structure that is more rigid than the second portion. The first portion also has a partition wall surface that separates the inner chamber of the second portion from the solid section of the first portion.
