Abstract: Disclosed is a process for the production of a shaped article from a thermoplastic resinous material, comprising the steps of heat plastifying the thermoplastic material; injecting the heat-plastified plastic material into a forming tool having a first shape configuration and at least one parting plane, to form a pre-form of the thermoplastic material; subjecting the thermoplastic material pre-form in the forming tool to a cooling phase; providing at least a partially new second shape configuration to the forming tool containing the pre-form; and during the cooling phase subjecting the pre-form in the forming tool having the second shape configuration to at least one pressure treatment under elevated pressure to produce a shaped article. Also disclosed are several embodiments of apparatus for carrying out the process.

Abstract: The application discloses a process for the preparation of plates, films, sheets, strips, rods, molded parts, objects or profiles of high mechanical strength, from thermoplastic synthetic resinous materials, whereby the thermoplastic material is initially heated in an extruder or a similar installation equipped with a mixing and heating device to at least its melting or softening point, the emerging extruded mass subjected during or after a cooling process in a forming device, pressure drawing device or other accessory installation to at least one pressure stretching at a pressure from about 90 .sup.N /mm.sup.2 to 1500 .sup.N /mm.sup.2, preferably from about 155 .sup.N /mm.sup.2 to 1000 .sup.N /mm.sup.2, and/or to at least one pulsating pressure or shearing pressure treatment. Preferably, the pressure stretched or shearing pressure treated synthetic plastic material is subjected subsequently to at least one further tempering, preferably cooling and/or processing step.

Abstract: Disclosed is a composition and method for preserving wood and construction materials made of wood. The composition comprises more than about 65% by weight of at least one difficulty volatile organic-chemical solvent having a flash point higher than about 30.degree. C. and of between about 0.35% by weight and 10.0% by weight of a specific fungicidal agent which is soluble, or at least partly soluble, in the organic-chemical solvent. The specific fungicidal agent is a mixture of N,N-dimethyl-N'-phenyl-N'-(fluoro dichloro methylthio) sulfamide and N,N-dimethyl-N'-(p-tolyl)-N'-(fluoro dichloro methylthio) sulfamide, in the proportion, by weight, of between about 25:10 and 10:30 and preferably between about 15:10 and 10:15. If desired, between about 0.1% by weight and 7.0% by weight of a soluble insecticidal agent may be added to the composition.

Abstract: Vertically oriented cathode grids or cathode plates, adjacently situated at closely spaced intervals in a cathode box, are cleaned by spraying jets of liquid onto the cathode surfaces at an angle of about 10.degree.-50.degree. and at a pressure of about 60 to 140 atmospheres, while moving the liquid jets uniformly along the cathode surfaces. A device for performing this process comprises a bar shaped spraying means comprising spraying nozzles which are connected to pressure resistent feeding means for the liquid.
