Abstract: A capping machine includes a gripper having a pair of gripping arms provided on an outer peripheral portion of a rotating body and configured to grip a cylindrical portion of a vessel, an opening and closing device configured to open and close the gripping arms, and a capping head liftably and rotatably provided on the rotating body. The gripping arms are arranged symmetrically with respect to a radius of the rotating body. The gripper has a protrusion for preventing the vessel from rotating on a vessel gripping surface of the gripping arms. The gripping arms have outer and inner gripping surfaces which are connected in a V shape. The protrusion is formed only on the inner gripping surface of a right gripping arm. A cap held by the capping head is screwed onto the vessel while sticking the protrusion into the cylindrical portion.

Abstract: The invention relates to a method and apparatus for removing nitrogen oxide from gas (exhaust gas) discharged, for example, in the steps of plating, washing with acids, dissolution, etc. The removing method comprises making a liquid capable of absorbing and removing nitrogen oxide adhered onto the surfaces of glass fibers followed by making a gas containing nitrogen oxide brought into contact with said glass fibers while making said nitrogen oxide absorbed by the liquid adhered onto the surfaces of said glass fibers to thereby remove said nitrogen oxide from said gas. According to this method, since a gas containing nitrogen oxide is brought into contact with a liquid capable of absorbing and removing nitrogen oxide from the gas, that has adhered on the surfaces of glass fibers, the nitrogen oxide is efficiently absorbed by said liquid and is therefore efficiently removed from said gas.

Abstract: A method of forming a composite material including the steps of: providing a surface against which the composite material can be molded; providing a plurality of discrete filler particles; placing a plurality of discrete filler particles against the surface; preventing the particles from shifting freely along the surface; directing a liquified matrix material against the particles on the surface; and solidifying the matrix material to unite the discrete particles and matrix material into a composite structure.
