摘要:
A drawing punch for use in drawing foils in a die which converges in the direction of drawing. The punch has a rigid core, a cylindrical elastic body on the core and surrounding the core with a cavity therein around the core and opening out of the end of the body facing the direction of drawing. A rigid support member is provided on the core against which the other end of the body is supported. The radial cross-sectional area of the cylindrical elastic body increases from the firstmentioned end of the body toward the other end, and the peripheral surface of the cylindrical elastic body is at a positive angle to the axis of the punch of from 0.degree. to 20.degree.. The cavity has a volume which becomes zero just before the end of the stroke of the punch into the die.

A noise control apparatus for reducing a sound volume of a noise propagating from a noise source such as a railroad includes a sound arresting wall placed apart from the noise source. Means for shifting in phase and refracting the acoustic wave of the noise is disposed at substantially the top of the noise arresting wall. The above means, for example, has a plurality of passageways extending substantially along the propagating direction of the acoustic wave of the noise and the length of the passageways varies. Through the above means, a part of the acoustic wave from the noise source is refracted and the phase thereof is shifted to be a refracted propagating sound, which thereafter interferes with the other part of the acoustic wave directly from the noise source to thereby reduce a sound volume to a great extent.
摘要:
A corrosion- and abrasive wear-resistant composite material for use in centrifugally cast linings composed of a matrix of a metal having corrosion-resistance and an abrasive wear-resistant reinforcing material dispersed as particles in the matrix. The reinforcing material has a higher hardness and a smaller specific density than the matrix.

Porous flame retarded acrylic synthetic fibers consisting of cellulose acetate and a modacrylic copolymer containing vinyl chloride and/or vinylidene chloride are produced by spinning an organic solvent solution of a polymer consisting of cellulose acetate and the above described modacrylic copolymer into a coagulation bath, primarily drawing the spun fibers at a draw ratio of 2.5.about.8.0, drying the water swelled fibers at 100.degree..about.180.degree. C. to a water content of no greater than 1.0% by weight and secondarily drawing the dried fibers under wet heat at a draw ratio of no greater than 3 times.
摘要:
A composite coated metal sheet suitable for outdoor building materials and having excellent weatherability, corrosion resistance and formability is provided herein by coating a metal sheet with a composite material essentially consisting of polyvinylchloride resin and flake-like aluminum powder, and in certain cases a metal powder and an alloy powder of zinc, tin and lead. Said composite coated metal sheet may be overlaid with an acrylic-type resin film.

This invention relates to a sintered alloy of a boride containing iron consisting essentially of a hard phase composed mainly of iron boride or a multiple boride containing iron in which a part of iron boride is substituted by a non-ferrous boride or multiple boride and a metal phase composed of at least one metal selected from Cu, Co, Ni, Fe, Cr, Mo, W, Ti, Zr, Hf, V, Nb, Ta and alloys composed mainly of these metals, wherein the boron content is 3 to 20% by weight, and to a method of making such sintered alloy. The sintered alloy of this invention has a hardness higher than that of high speed steel and has such high hardness and strength that it is comparable to alloys of cemented carbide, and it is characterized in that it has a good corrosion resistance at room temperature, a high oxidation resistance at high temperatures, a high hardness and a high strength, and that it is cheaper and lighter than cemented carbide. This invention provides a novel sintered high-hardness material which will take the place of cemented carbide or high speed steel.
