Abstract: The present invention relates to a foamable aerosol concentrate composition, a foamable aerosol agricultural-chemical composition, and a method of controlling diseases and insect pests; particularly, relates to a foamable aerosol concentrate composition suitable for horticulure as a pastime in which an active ingredient of agricultural-chemicals having insecticidal and/or fungicidal activities and also having systemic action through a plant body and a surfactant are dissolved in glycols that are liquid at normal temperature, a foamable aerosol agricultural-chemical composition including the concentrate composition and a propellant both of which are filled in an aerosol container, a method of controlling diseases and insect pests through spraying application of the foamable aerosol agricultural-chemical composition to stems and/or branches of plants to be treated.

Abstract: A method and apparatus for feeding yarn during a single stitch of a needle such that the mean rotational frequency of a yarn feeding drum connected to a first and second driving member is changed during the single stitch of the needle so as to regulate and control the feeding of the yarn and provide a maximum and minimum yarn length in the resulting stitch or selectively provide a yarn length between the maximum or minimum length.

Abstract: A cylindrical catalyst element comprising a heat-resistant metal in the form of a wire mesh or the like, a silica cloth supported by the mesh and having a catalyst disposed on a surface thereof adjacent the interior of the cylinder, said element being disposed adjacent the interior wall of an exhaust system upstream of a main catalyst device for cleaning the exhaust gases of an internal combustion engine.

Abstract: A catalytic converter for purifying the exhaust gases from an internal combustion engine, wherein a plurality of catalytic layers are arrayed in series and spaced apart by a predetermined distance from each other, and bypass paths are provided in such a way that except for the last catalytic layer, a part of the exhaust gases may bypass each catalytic layer without making contact therewith and may directly flow into the next catalytic layer.
