  • Patent number: 4752316
    Abstract: Apparatus and process for compressing moisture containing material including a pair of opposed rolls for receiving and advancing the material therebetween to apply rolling load thereto to compress the material and remove at least a portion of said moisture therefrom, and differential means for causing one of said rolls to rotate at a lower speed than the rolling speed of the other of the rolls, the differential rolling speeds developing friction between the rolls causing the rolls to be heated and apply heat to said material to further remove moisture therefrom, to cause the compressed material to adhere to the one roll and to cause the removed moisture to adhere to the other roll, also alone and in combination, apparatus and process of decomposing organic material such as animal biomass by the action of aerobic microorganisms in the presence of oxygen, including introducing the organic material into a container having an end adapted to receive the organic material and an output end adapted to discharge the o

  • Patent number: 4436682
    Abstract: A flowable thermoplastic polymer powder is fed to the nip of a pair of cooperatively rotating compression rolls whereupon the polymer feed is passed between the rolls which compact and cause the particles to coalesce into a shaped article which thereupon emerges from between the rolls in the form of a sheet or film. During the operation, the circumferential speed of the rolls is maintained essentially equal to the linear speed of the sheet or film exiting therefrom. The sheet or film is withdrawn from between the rolls under tension at a force which is adjusted so as not to exceed the elastic limit of the resulting sheet or film product. Flowable thermosetting polymer powder is also compacted into fully dense products by feeding the powder to the nip of a pair of cooperatively rotating compression rolls, whereupon the polymer feed is passed between rolls which compact and cause the particles to cold weld.

  • Patent number: 4029476
    Abstract: A brazing alloy is provided consisting essentially by weight of about 30 to 50% copper, about 10 to 20% manganese, about 3 to 25% iron, about 0.5 to 4% silicon, about 0.5 to 2% boron and the balance essentially nickel.
