  • Publication number: 20030006519
    Abstract: The invention pertains to a method for treating foamed plastic particles 32 that are present in pourable form, as well as a device for carrying out the method. The invention is characterized by the fact that the foamed plastic particles 32 are reduced in volume in an evacuated environment and then introduced into a mold 10, 34, 46, 52, 56, in which the foamed plastic particles 32 are subsequently restored toward their original outer shape in a non-evacuated environment.

  • Patent number: 6288329
    Abstract: A foldable blank includes a substrate and a conducting layer. The substrate is folded so as to form a component housing. When the substrate is folded to form a housing, the conducting layer provides electrical shielding to devices situated within the housing. The housing has holes situated therein to accommodate air flow and external connections to devices located within the housing. The housing may be employed to envelop a chassis manufactured from expanded polypropylene.

  • Patent number: 6011701
    Abstract: The housing assembly for holding device components comprises a housing and a chassis and can be integrally coupled to a standard piece of furniture. The housing may be in the form of a drawer which can be inserted and withdrawn from a standard unit of furniture such as a desk or cabinet. The drawer has perforations in its bottom and sides for air flow and is preferably made from a metal or metallic material but alternatively may be made from a non-metallic material which is lined with a metallic film. The chassis is made of plastic, preferably expanded polypropylene and may comprise two parts in which are secured equipment components. Projections extend from the sides of the chassis and extend to the drawer walls and thereby create air ducts through which air may flow to cool the components situated in the chassis. Plastic inserts may be placed in the air ducts created by the projections so as to direct the air flow within the assembly.

  • Patent number: 4306054
    Abstract: The invention relates to the continuous production of epoxide resins of low, medium and high molecular weight, and also to their purification and to that of the waste water. No raw materials are required in addition to epichlorohydrin, 2,2-bis-(4-hydroxyphenyl)-propane, alkali hydroxide and water. The raw materials are fed at a shear rate of 7.5-50.times.10.sup.4 sec.sup.-1 (at a peripheral speed of the rotor of 15 to 50 m/sec and a distance of the rotor elements from the stator elements of 0.01 to 0.02 cm) continuously into a reactor and mixed in such a way that by the concentration of high kinetic energy in a very limited space the interfaces of the phases of the heterogeneous reaction mixture are increased to an extreme extent and the reagents are caused to react with one another within 5 sec. at the latest.The reaction proceeds very evenly in the reactor.
