  • Patent number: 5064099
    Abstract: A particulate material feeder includes a hopper sectioned into two receptacles for accommodating two different kinds of particulate materials. Each particulate material falling down through a bottom opening of the receptacle is introduced into a feed channel defined between a feed roller having a frictional periphery and a control gate having a semi-circular cross-section. Thus, a pair of feeding systems for two different kinds of the particulate materials are symmetrically provided within a single apparatus. An opening degree of the feed channel may be controlled separately and independently in each feeding system so that a definite mixing rate of the two kinds of particulate material can be obtained as desired. On the contrary, the feed rollers provided in the two feed systems are driven by a single driving source and are thus rotated at the same speed.

  • Patent number: 4793523
    Abstract: A metering mechanism comprises a housing (7) with a material inlet (12) and a rotary metering member (27) that is rotatably mounted between side walls (8,9) of the housing with its periphery exposed to a chamber (48) within the housing so as to meter material from the chamber as it rotates, characterized in that a removable insert (74) is provided that is a close fit in said chamber and has a passage (75) through it that communicates at one end with said inlet (12) and at the other end with the periphery of the rotary metering member (27) so that the effective volume of said chamber (48) is reduced to the volume of said passage (75). Thus, if the metering mechanism incorporates the known shutter-type tramlining device in which a shutter (24) serves to close the inlet (12) to the housing, the quantity of speed retained in the chamber within the housing is reduced and therefore the length of a bout that will be sown after closing the shutter will be correspondingly reduced.

  • Patent number: 4597694
    Abstract: A device for introducing dosed or proportioned quantities of pulverized solid materials into a carrier gas stream is presented. The device comprises a housing which defines a flow chamber in the axial direction for the flow of pressurized fluid or carrier gas. The housing also has a side aperture therethrough. The side aperture is connected to a container holding pulverized materials. Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing. The outer sleeve communicates with the aperture while the inner sleeve has an axial bore which provides a passage for the carrier gas. Upon rotation of a sleeve, slots provided on each sleeve will align and overlap with each other and with the aperture to define a variable sized passage between the container and axial bore whereby the pulverized material is delivered therethrough to the carrier gas stream.
