Abstract: The present invention relates to a device for extracting and proportioning pulverulent products comprising a hopper and coaxial screws with threads of opposite directions, driven in rotation in a cylindrical conduit, which screws are separated from each other by the wall of a tube coaxial to the screws and to the conduit, the screw of smaller diameter rotating inside the tube to convey the product therein in one direction and the screw of larger diameter rotating outside said tube to convey the product in the opposite direction, in the space defined between the tube and the conduit, said latter comprising on its periphery at least one orifice for the flow of the product, wherein said screws are composed of wires helically wound in the manner of a spring, and the tube in which the so-called extraction screw, of smaller diameter, is mounted, comprises on its periphery and on the hopper side an opening for the inlet of the product, in front of which said screws extend at least partially, which product, after hav

Abstract: Linear objects are removed from a processing drum, one at a time and are deposited to form groups or bundles of said objects in the slots of a transfer drum. Then the groups or bundles of said objects are pushed out of the slots in the transfer drum for feeding same to another apparatus.

Abstract: A crop conveyor assembly having regularly spaced flights and discharge means to minimize bruising is disclosed. A crop conveyor having a feed section and a discharge end is equipped with regularly spaced flights wherein said flights have upright, regularly spaced, flexible fingers. Discharge means to minimize crop bruising is located adjacent the discharge end of the conveyor. The discharge means comprises slender, spaced members through which the fingers of the flight pass as the conveyor changes direction at the discharge of said conveyor. Disk members attached to a common axle perform well as the discharge means.

Abstract: Apparatus for changing the spacing between two neighboring rows of parallel cigarettes which are transported sideways has a first fluted drum which delivers the two rows of cigarettes to a first transfer station where the cigarettes enter radially extending flutes in the upper end faces of two coplanar disks which are eccentric to each other and one of which surrounds the other disk. The disks transport the cigarettes through 180 degress to a second transfer station where the cigarettes are picked up by the flutes of a second fluted drum which is coaxial with the first drum. The distance between the two rows of cigarettes increases or decreases gradually during transport by the disks.

Abstract: A dispensing apparatus is provided for feeding an air containing material in such a way that a constant volume of solid material per unit of time is fed. Said apparatus comprising at a filling station a throwing device by means of which the material is thrown into compartments of a dispensing device whereby air is squeezed out of the material so that a constant volume of solid material is contained in each compartment. The compartments are successively moved to a discharge station wherein the compartments are emptied under influence of gravity and air under pressure blown into the compartment being emptied.

Abstract: This invention pertains to an arrangement for conveying, handling and storing of solid bodies, bulk material, jelly products or liquids, which arrangement characterized by a plurality of rotary shafts arranged at a distance apart from each other, each of said shafts being equipped with one or more cams, the distance between adjacent shafts being approximately equal to or greater than the length of the cams.

Abstract: An apparatus for the high-speed handling of integrated circuit parts. The apparatus consists essentially of two parts, a test wheel and a sort wheel. It singulates parts from a reservoir of untested parts, moves the parts to electrical contacts for test, moves the tested part out of the contacts and sorts the part into the proper bin.

Abstract: A pair of rollers define between them a narrow gap which is supplied with sludge to be treated. The sludge is conveyed by one of the pair of rollers to a third roller in contact with the conveying roller. The third roller is spaced a short distance from a rotating drum carrier to which is applied a thin film of the sludge. The sludge is applied to the carrier by the formation of a sludge bulge, which is an accumulation of sludge, in the area defined by the carrier, the third roller, and the conveying roller. The drum carrier picks up the sludge from the sludge bulge forming a film of sludge whose thickness is limited by the spacing of the third roller from the carrier.

Abstract: An apparatus for grinding hard grains and similar materials having a unique force feed arrangement which insures uniform material feed to the grinding members and a resulting uniform output of ground material from the apparatus.

Abstract: An article handling system is provided which includes means to receive a series of articles progressively, continuously, and at minimum linear acceleration; means to distribute the articles to a plurality of work stations progressively, continuously, and at minimum linear acceleration; to halt each article at a respective work station for a given period; and to withdraw the articles progressively, continuously, and at minimum linear acceleration.
