    Abstract: A granulating and coating machine for use in granulation, coating, mixing, drying etc. of powdery or granular materials. The machine includes a casing for holding the powdery or granular raw materials, a rotator for performing granulation or coating arranged at the bottom of the casing and formed with at least one ventilating porition, an annular slit formed between the periphery of the rotator and the inner wall of the casing. A gas flow adjusting mechanism including two separated ducts for gas flow is provided in order to control independently the rate of gas fed through the ventilating portion and the slit gas fed through the slit. An agitator for agitating the powdery or granular materials and a disintegrator for breaking undesirously large particles of the powdery or granular materials may be provided above the rotator. The slit may be formed by an annular slit forming ring mounted on the inner wall of the casing. The slit forming ring may be moved vertically by a slit adjusting mechanism to change the width of the slit so as to adjust the rate of flow of the slit gas fed through the slit.

    Abstract: Apparatus for feeding flock fibers comprising an upwardly open flock-receiving hopper. The hopper has a bottom discharge passage under which is mounted metering apparatus providing a plurality of discharge openings of controllably variable size. An upper impeller having a plurality of downwardly angled blades is rotatably driven within the hopper passage to urge the flock fibers to fall downwardly through the discharge openings into a cylindrical pump chamber. A lower impeller is rotatably driven within the pump chamber to sweep falling flock fibers into a pump throat in communication with a venturi flow tube through which a supply of air is passed. The air flowing through the venturi flow tube creates suction to draw the fibers within the throat into the venturi flow tube for entrainment with the air stream.

    Abstract: 1,223,243. Pneumatic conveyers. LA SOUDURE ELECTRIQUE AUTOGENE, PROCEDES ARCOS, S.A. 1 Oct., 1969 [15 Oct., 1968], No. 48294/69. Heading B8A. A device for feeding a non-flowing powder from a rotatable container 32 into a pneumatic conveying line 56 comprises a rotatable disc 20 extending into powder in the container and having holes 46 therein distributed around and spaced from its circumference, the powder entering the holes from both sides of the disc, and rubber faced shear plates 40, 41 on opposite sides of the disc for removing excess powder therefrom prior to the sequential co-operation of the holes 46 with both the discharge line 56 and a gas pressure supply line 57, whereby the powder is conveyed away. The disc 20 may rotate about a horizontal axis but is preferably rotatable about an inclined axis whereby due to the rotation of the container 32, powder is assisted into the holes 46 from one side of the disc as the hole moves into the powder and from the other side as the hole moves out of the powder, a pair of ploughs 38 also assisting powder into the holes. Further holes 48 in the disc tend to relieve pressure build up in the powder. The circumferential spacing between the holes 46 is less than their diameter whereby there is always a part of a hole 46 in communication with the discharge line 56. The whole device is mounted in a gas tight enclosure Fig. 6 (not shown) comprising a lower portion housing the feeding device and its drive, and an upper portion formed as an air-lock and housing an apparatus for filling the container. The latter apparatus comprises a powder holding drum rotatable in steps about a vertical axis, and at each step a plunger displaces a plug of powder through an aperture in the drum base into the container in the lower portion, the plunger sealing the passage between upper and lower portions when the drum is being refilled. A plough in the drum distributes the powder once a plug thereof has been dispensed.
