Abstract: A plate catalyst body for denitration wherein a catalytic substance is supported on a porous metallic plate body having three dimensional network, which has an excellent retention of catalyst and an easy producibility, the porous metallic plate body being able to be uneven or have protrusions.

Abstract: A hose joint, used in the neighborhood of a radiant heat source such as an exhaust manifold in a vehicle for example, having on one end thereof a hose attaching portion and on the other end a fixing portion, provided with a sheltering cover secured on the hose joint in the middle between the hose attaching portion and the fixing portion for being interposed between the radiant heat source and the hose so as to protect the latter from the former's heat. The sheltering cover is a metallic plate which is metal-plated for effectively reflecting the radiant heat; it is preferably disposed perpendicularly to a line linking the hose attaching portion and the radiant heat source irrespective of the shape of the hose joint, for example, straight or bent.

Abstract: A mechanical parking brake mechanism which comprises firstly a sector pulley pivoted on the backing plate of a brake drum to guide an intermediate portion of a parking brake wire and formed at its guide face with at least two radial recesses spaced from each other at a predetermined interval and secondly a parking brake wire integrally provided at its intermediate portion with at least two projections to be selectively engaged with the respective recesses of the sector pulley in accordance with the length of pulling stroke of the parking brake wire, thereby to avoid undesired excessive force acting on the parking brake wire and to enhance transfer efficiency in the input force applied to the parking lever of the mechanism.
