  • Method of manufacturing molded articles from a kneadable material, e.g., clay
    Patent number: 4187268
    Abstract: Process by which moulded articles are maufactured from clay. A continuously produced strand of the material in question is sprinkled with sand, whereafter at one location a piece is severed from the end of the strand at regular intervals, by a cutting apparatus, which piece then enters a mould. In the course of all phases of the process the strand and each severed piece thereof remain directed along one vertical downwardly directed line of movement.

  • Method for dewatering sludge
    Patent number: 4101400
    Abstract: Sludge is dewatered to a dry content of more than 25% by a combination of(a) pre-conditioning the sludge by flocculation with polymeric flocculants;(b) pre-dewatering the conditioned sludge to a certain solid content corresponding with shovel consistency;(c) thereafter dewatering the sludge further through electroendosmosis under pressure.This combination renders it possible to produce a product having a dry content of more than about 30% irrespective of the origin of the sludge.
