Patent number: 8734061Abstract: Cylindrical prescription containers are propelled through a pneumatic transport system at high speeds by low pressure, high-velocity air. Upon arrival at destination stations within the transport system, curvilinear decelerators slow them by directing them through a plurality of curved paths where they dissipate momentum. Once slowed, the containers are deposited upon a moving conveyor to be staged into the next processing station at an even pace. The decelerators comprise curved vanes surrounding the container path, the vanes being held in a fixed, curvilinear relation to each other and the container by a series of yokes surrounding and engaging the vanes. The conveyor is driven by a servo motor controllable by the transport system to pace containers as needed by the next processing station.Type: GrantFiled: August 21, 2009Date of Patent: May 27, 2014Assignee: Tension International, Inc.Inventor: Robert Terzini

Patent number: 6609870Abstract: A granular semiconductor material transport system capable of continuous, non-contaminating transfer of granular semiconductor material from a large source vessel to a smaller and more manageable target vessel. Movement of the granular material is induced by flowing transfer fluid. The system includes a source vessel, a feed tube, a process vessel, a target vessel and a vacuum source, or mover. The source vessel contains a bulk supply of granular material to be transported. A feed tube received within the source vessel transfers the granular material entrained in a transfer fluid from the source vessel to the process vessel. The process vessel separates the granular material from any dust particles and deposits the granular material in the more manageable target vessel. The vacuum source sealably connects to the process vessel to evacuate the process vessel to set the granular polysilicon in motion within the system.Type: GrantFiled: October 23, 2001Date of Patent: August 26, 2003Assignee: MEMC Electronic Materials, Inc.Inventors: Dick S.

Patent number: 5024561Abstract: The bulk material feeder of the present invention, because of the need for cleaning the inside of the feeder, jets out pressurized clean air into the equipment. The air is supplied through the piping used to supply resin pellets and nozzle to carry out the cleaning action, utilizing turbulent flow generated when the air current jetted out collides with baffles installed in the equipment. The air and pellets are easily aspirated and cleans fines adhered to internal walls of the hopper since, naturally, resin pellets remaining in the equipment are destroyed by the turbulent flow. Also resin pellets are destroyed a little by the impact when colliding with internal walls of the hopper, and due to other causes. Residual pellets aspired to the outside and fines adhered to the inside are collected, and internal cleaning can be accomplished in an extremely short time. A bulk material feeder is thus provided with an internal cleaning mechanism.Type: GrantFiled: May 25, 1989Date of Patent: June 18, 1991Inventor: Isao Kitagawa
-
Patent number: 4834544Abstract: A blender for solid particulate material such as plastic pellets which includes an apparatus for separating a fine fraction of material from the plastic pellets. This is accomplished by a separator shell which surrounds a vertical lift pipe in the blender. Gas under pressure is utilized to circulate material through the lift pipe from the bottom of the vessel to the top of the vessel to blend the material. As material is discharged from the vertical lift pipe, the air supplied through the lift pipe for lifting material flows through material dispersed within the separation zone to entrain the fine material and convey it through a vent to a high efficiency dust collector. A by-pass conduit and by-pass control valve are provided to control the velocity of gas through the separation zone to control the size particle of the fine fraction which is separated.Type: GrantFiled: July 6, 1987Date of Patent: May 30, 1989Assignee: Fuller CompanyInventor: Kermit D.

Patent number: 4552490Abstract: A control valve assembly for controlling particulate solids feed upward into a fluidized bed reactor, utilizing a purged valve seat mating with a poppet head and valve stem having a vented clearance space. The valve seat surface and a stem clearance space are each purged by a clean externally supplied gas, the solids flair in an elbow-shaped passageway are fluidized by air supplied through booster nozzles, and the valve stem is operated by a pneumatic actuator. A particulate solids material such as coal is transferred by a screw conveyor through a horizontal conduit, and then fed through the elbow-shaped passageway and the poppet valve seat upwardly into the reactor fluidized bed.Type: GrantFiled: January 7, 1985Date of Patent: November 12, 1985Assignee: Foster Wheeler Energy CorporationInventor: Thomas J.

Patent number: 4475849Abstract: A method and a device for the uniform distribution of a bulk materials stream, particularly one conveyed pneumatically, onto a more extended cross-sectional area possibly divided up into partial stream cross-sections by partitions, is distinguished by the bulk materials stream passing through an elongate vertical charging space, at the end of which it is gathered into a narrowing outlet channel in which the bulk material shows an essentially uniform cross-section distribution and that this bulk materials stream then passes to the tip of a coaxially arranged distribution cone which deflects the bulk material sideways uniformly in all directions and in this way forms a hollow bulk materials curtain of uniform circumferential distribution. This bulk materials curtain can be used as such, for instance in a vessel in which the bulk material is sprayed with liquid, or can be used for the further subdivision into partial streams.Type: GrantFiled: September 30, 1982Date of Patent: October 9, 1984Assignee: Claudius Peters AGInventor: Peter Hilgraf
