    摘要： The mold for making a rectangular foam block from a plurality of blowable and sinterable plastic pieces, especially foamed polystyrene pieces, with the help of steam comprises a rectangular inner mold with a plurality of inner mold walls movable from each other and an outer mold tightly closable surrounding the inner mold having at least one steam inlet and an air evacuation and vacuum pump connector pipe. This mold is especially easy to construct when the outer mold comprises a pipelike pressurizable container with a front mold wall comprising a pressure-tight door and with a block ejector mounted in a rear mold wall which can be pushed approximately perpendicularly to the rear mold wall into the inner mold.

    摘要： A method of manufacturing an expandable member comprising the steps of separating a shaped member from a sheet of cellular spongy material, soaking the member in a solution containing a water soluble binder and water, compressing the member into a container and drying the compressed member. The dried member expands to its original shape and size when placed in water.

    摘要： A mould portion and/or protective element of the type consisting of a material subjected to deformation is disclosed. A method and a device for manufacturing such a mould portion and/or protective element are also disclosed.The mould portion and/or protective element is preferably intended to be used as a mould portion in moulding an article and/or as a protective element to prevent access of soil and water to a surface portion of the article during transportation and storage thereof.Such materials subjected to dimensional changes as can be used as mould portions and/or protective elements present the advantages of being inexpensive and permitting removal of the article without difficulty. One such material is for example cellular plastics. The dimensional changes, however, have entailed so great difficulties in using mould portions and/or protective elements of such materials that they have made the use of the material impossible.To eliminate the above mentioned disadvantage the mould portion and/or protective element of a material subjected to dimensional changes is manufactured with the desired dimensions, starting from at least one blank, immediately before the mould portion and/or protective element is used to mould the article or join the mould portion and/or protective element to the article to protect the surface portion thereof. Alternatively, the mould portion and/or protective element of a material subjected to dimensional changes is manufactured with the desired dimensions, starting from at least one blank after the blank has reached dimensional stability.

    摘要： In the manufacture of skinned foam a technique for matching the viscosity of the skin as well as the foam so that both flow uniformly through the die includes the addition of blowing agent to all of the layers of the structure. To prevent foaming of the skin layers, nucleating agent is not added at those layers and the temperature is controlled so as to prevent nucleation without a nucleating agent. More specifically, the skins are kept above the boiling point of the blowing agent at atmospheric pressure and melt temperature, but below the temperature at which homogeneous nucleation occurs.

    摘要： The invention provides a method for producing permeable polymeric membranes comprising decomposing, in a polymeric matrix, molecular moieties, bound to the polymer or contained in compounds dispersed therein, into smaller, discrete, molecular units, whereby the smaller, discrete molecular units, which are formed, spontaneously leave the polymeric matrix and a membrane of defined permeation characteristics is obtained.

    摘要： A process of pre-foaming blowing agent-containing plastic materials, in which the plastic material particles which have been pre-foamed by the addition of heat are transferred without an intermediate resting stage from a sealed pre-foaming chamber into a drying and stabilizing chamber, with a vacuum being maintained during the drying and stabilizing operation.An apparatus for the performance of the process includes a pre-foaming chamber, beneath which there is provided a chamber in which the pre-foamed plastic material is dried and stabilized. The charging opening of the drying and stabilizing chamber is directly under the discharge opening of the pre-foaming chamber and is hermetically sealable by means of a slide valve.
