The above composition is formed by extrusion into a hard polyvinyl chloride resin open-cell foam.

Abstract: In the production of a decorative sheet, a synthetic resin paste is first applied onto the upper surface of a substrate sheet to form an undercoat layer. Then, one or more pastes, each being of the same material and having approximately the same viscosity as the paste of the undercoat layer, are laterally sprayed so as to drop onto the undercoat layer. The result is a smoothing phenomenon, with the pattern layer cooperating with the undercoat layer to form a smooth patterned surface. Finally, the pattern layer is heated and jelled.

Abstract: A descent slowing device is disclosed that includes a housing having an input driving shaft and a driving pulley fitted thereon and accommodating therein a gear train and an impeller adapted to be driven through the gear train by a driving pulley about which is trained a rope or line. When one end of the line descends owing to a load acting thereon to rotatively drive the driving pulley and hence the impeller, the rotation of the impeller is restrained by rotation control oil or similar viscous fluid in which the impeller is immersed, thereby controlling the descent of the load at a constant slow speed. According to the invention, the impeller comprises four blades, the rotating speed ratio of the impeller to the input driving shaft being more than 40:1. Moreover, the driving pulley is formed with a rope receiving groove comprising line abutting projections and non-contact recesses alternately arranged.

Abstract: A process for preparing an open-cell structure from a vinyl chloride resin. The process includes mixing a vinyl chloride resin, stabilizer, plasticizer, surface active agent, azodicarbonamide and 4,4'-oxybisbenzenesulfonyl hydrazide to form a vinyl chloride resin paste. The vinyl chloride resin paste of step (a) is rendered alkaline, and mixed to form a uniformly-mixed paste. The paste is permitted to expand, and then heated to cause gelation.

Abstract: A method for making a vinyl chloride resin sheet having a raised pattern thereon. The method comprises the steps of providing an open-celled vinyl chloride resin sheet and printing a portion of the sheet with a composition comprising a cross-linkable compound in accordance with the pattern to be formed. The printed sheet is then dried and subsequently heated to a temperature higher than its softening temperature whereby the open-celled unprinted portion of the sheet is depressed and whereby the printed pattern remains open-celled and stands in relief with respect to the depressed portion.
