  • Device for heat-treating bulk materials in feed screws and bulk material drying method
    Patent number: 6035546
    Abstract: Device for the thermal treatment of bulk material with a screw conveyor transporting the bulk material which is equipped with infrared heat radiators in a tempering zone, characterized in that the infrared heat radiators are arranged in the screw conveyors in the central area of the rotation diameter. The device is also characterized in that the infrared heat radiators are mounted in a radiation-permeable screw shaft. The walls of a screw trough of the screw conveyor have an infrared-reflecting coating or are made of an infrared-reflecting material.

  • Device for the relaxation of bulk articles containing drawn thermoplastics and for the selective softening of thermoplastics in a mixture flow for recycling
    Patent number: 5993052
    Abstract: A worm or screw conveyor for the thermal treatment of a bulk containing thermoplastics and which has an elongated housing along which the bulk material is conveyed by a worm or screw. The worm or screw has a certain peripheral diameter and is rotatable about the worm axis to displace the bulk material therealong and an infrared heater is located in the housing centrally of the peripheral diameter for directly exposing bulk material in the housing to infrared radiant energy to heat the bulk material.

  • Sound absorber for motor vehicles
    Patent number: 5681072
    Abstract: A sound absorber for motor vehicles is constructed in the form of a double-wall, flat resonant body (1) with a perforated front wall (3) facing the noise source and a substantially unperforated rear wall (4). The sound absorber is constructed as a combined plate/perforated resonator and is able to absorb both high and lower frequencies.

  • Shaped laminate, particularly internal lining part for motor vehicles, as well as process and apparatus for the production thereof
    Patent number: 5670235
    Abstract: The invention relates to a shaped laminate, particularly an internal lining part for motor vehicles. The laminate (1) has a substantially stiff supporting sheet (2) of thermoplastic material. The latter is covered on at least one and preferably both sides with a surface layer (3, 4) in the form of a nonwoven fabric. The joint between the nonwoven fabric and the plastic sheet is a thermal bond. For forming the bond the nonwoven fabric at least partly and preferably completely is made from the same type of plastic as the sheet. The invention also relates to a process and an apparatus for producing the laminate. For forming the adhesive joint the sheet is heated on at least one side to a temperature in the adhesive range of the thermoplastic material, the sheet interior being kept at a lower temperature. As a result of this procedure the nonwoven fabric structure is protected during the adhesion and shaping process.
