  • Patent number: 10145101
    Abstract: A microporous insulation material mixture is blended and the blended mixture is spread across a lower conveyor belt which is trained over rollers. To aid the spreading of the mixture a spreading device is used. The mixture is delivered by the conveyor to a pressing system which in this case comprises an upper conveyor belt. The pressing system also comprises a nipping means provided in this case by a plurality of upper and lower nipping rollers. The gaps between the individual rollers are adjustable. An upper fleece liner is led from a delivery roller to lie between the upper conveyor belt and the insulation mixture and a lower fleece liner is fed from a delivery roller to lie between the insulation mixture and the lower conveyor belt. The fleece liners may be used to encase the core prior to enclosing in an envelope and applying a vacuum.

  • Patent number: 8679998
    Abstract: Initially, an Yb2O3 raw material was subjected to uniaxial pressure forming at a pressure of 200 kgf/cm2, so that a disc-shaped compact having a diameter of about 35 mm and a thickness of about 10 mm was produced, and was stored into a graphite mold for firing. Subsequently, firing was performed by using a hot-press method at a predetermined firing temperature (1,500° C.), so as to obtain a corrosion-resistant member for semiconductor manufacturing apparatus. The press pressure during firing was specified to be 200 kgf/cm2 and an Ar atmosphere was kept until the firing was finished. The retention time at the firing temperature (maximum temperature) was specified to be 4 hours. In this manner, the corrosion-resistant member for semiconductor manufacturing apparatus made from an Yb2O3 sintered body having an open porosity of 0.2% was obtained.

The claimed apparatus includes a flow through support device composed of ceramic, such as cordierite or silicon carbide, or a primarily nonferrous metal or stainless steel and coated with an oxide formation comprising hematite and bixbyite in a ratio from 1:1 to 9:1. The claimed apparatus can also include a diesel particulate filter coated with a coating comprising tin, aluminum and zirconium oxides prepared by a co-precipitation process and thereafter coated with platinum or other precious metal.
