Patent number: 10830361Abstract: A spreading control switch structure of a spreader has a spreading tube, a positioning member, a main tube and a switch unit. With the positioning member and the switch unit, the opening and closing state and the spreading amount of the present invention can be adjusted by the circular plate of the valve in the spreading tube. The size of the pipe in the spreading tube is opened to control the blanking amount. On the other hand, the circular plate of the valve can be kept opened in the spreading tube all time without the switching handle being pressed. Therefore, it is easier and less laborious to execute the spreading process.Type: GrantFiled: August 13, 2019Date of Patent: November 10, 2020Assignee: SK & Y AGRICULTURAL EQUIPMENTS CO., LTD.Inventor: Jui-Chang Wu

Patent number: 6584920Abstract: A system for maintaining an appropriate air flow in an air stream in an air seeder. A fan provides an air stream to carry agricultural materials for distribution across a width of a seeding implement. A tank contains a granular agricultural material and a metering device dispenses the material into the air stream. The system is calibrated such that a known weight of material is dispensed for each revolution of the metering device whereby the rotational speed of the metering device multiplied by the known weight per revolution results in a known per minute rate of agricultural material being dispensed into the air stream. A microprocessor is programmed to derive an appropriate fan speed for the per minute rate of agricultural material being dispensed and send a signal to a fan control to adjust the speed of the fan to correspond to the appropriate fan speed.Type: GrantFiled: September 17, 2002Date of Patent: July 1, 2003Assignee: Bourgault Industries Ltd.Inventor: Mark Cresswell

Patent number: 6478513Abstract: A fluid pumping assembly for pumping particulate material includes a pump housing defining a pump cavity including a pumping chamber for handling particulate material, a motive fluid chamber, and a moveable diaphragm. The fluid pumping assembly also includes devices for loading particulate material into the pumping chamber, and for injecting a high pressure, high volume purging fluid into the pumping chamber. Further, the fluid pumping assembly includes a control system having a control valve for shutting off flow of high pressure, high volume purging fluid into the pumping chamber when particulate material is being loaded into the pumping chamber, thus enabling dense phase loading of particulate material, and thereby optimizing a particulate material pumping capacity of the fluid pumping assembly.Type: GrantFiled: March 4, 2002Date of Patent: November 12, 2002Assignee: Xerox CorporationInventors: Fumii Higuchi, Ronald B.

Patent number: 6296425Abstract: An apparatus for dispensing particles includes a storage tank for containing particles to be dispensed a metering mechanism for transferring particles from the storage tank and an air distribution system for receiving particles from the metering mechanism The air distribution system includes a bank of tubes for transporting particles in a flow of air having a flow rate, and a damper mechanism at the bank of tubes for selective control of the flow rate within the bank of tubes. The apparatus for dispensing particles also includes an air flow source for providing a flow of air to the bank of tubes, a sensor located at each tube for providing a sensor output signal indicative of a value of a flow characteristic, and a controller operably connected to the sensors and to the damper mechanism.Type: GrantFiled: October 4, 2000Date of Patent: October 2, 2001Assignee: Flexi-Coil Ltd.Inventors: Russell J.

Patent number: 6283679Abstract: A seed cart for an air seeder is provided with pneumatic distribution system having a primary air distribution manifold. The primary air distribution manifold is provided with a top rank of venturis and a bottom rank of venturis for receiving an air stream from a blower which is divided into a top rank air stream and a bottom rank air stream. A selector valve is located above the top rank of venturis immediately below a product meter. The selector valve selectively directs metered product to either the top rank of venturis or the bottom rank of venturis. In a first position the selector valve directs metered product to the top rank of venturis in its second position the selector valve directs metered product to the bottom rank of venturis. Each selector valve is also provided with first and second air valves. In the selector valve's first position, the first air valve is open and directs air tapped from the top rank air stream to the product tank feeding product to the top rank of venturis.Type: GrantFiled: November 2, 2000Date of Patent: September 4, 2001Assignee: Deere & CompanyInventors: David Walter Gregor, Terry Lee Snipes, Donald Raymond Wisor

Patent number: 6257804Abstract: A powder metering apparatus for making available a powder, in particular for powder coating, and which comprises a metering pump with a rotatably driven metering disk arranged between two lateral plates. The metering pump includes an inlet, through which it receives a powder-air mixture, and an outlet that connects via a suction tube to an injector pump. From the outlet, the powder-air mixture conveyed by means of the metering disk to the outlet is sucked out by a vacuum flow that is generated in the injector pump and enters the metering pump via a suction inlet opening, and the powder-air mixture is then supplied to a consumer.Type: GrantFiled: August 13, 1999Date of Patent: July 10, 2001Assignee: Barmag AGInventor: Egon Gathmann

Patent number: 4930941Abstract: A customer terminal for a single tube pneumatic system for banking and the like features a two-piece carrier receiver which includes a carrier tray that first moves downwardly from a stationary receiver housing and then forwardly and upwardly to present a carrier in the tray to a customer, the tray and carrier remaining parallel to the receiver housing. The tray is resiliently mounted to the mechanism which manipulates it and the joint between the tray and housing is contoured both to improve sealing between the two parts and to reduce wear on the seal itself. The air pressure/exhaust ports into the carrier chamber within the receiver are disposed between the ends of the chamber in order to provide an air cushion for reducing the shock of an arriving carrier and to prevent loose items in the system from being sucked into the blower.Type: GrantFiled: November 21, 1988Date of Patent: June 5, 1990Assignee: Inter Innovation LeFebure Mfg.

Patent number: 4352603Abstract: A banking service pneumatic tube system teller terminal having a single conveyor tube. A carrier is transported in the system and is removable from the terminal housing formed of molded plastic material. The housing may be installed for carrier arrival vertically from above or below. The housing has an access opening closed by a cradle-door movable between open and closed positions. The cradle has a cylindrically walled carrier receiving compartment located between cylindrical end portions of the housing when the door is closed. One housing end portion is coupled with an end of the system conveyor tube. A carrier arrival switch is mounted on the cradle actuated by carrier arrival to automatically open the door by release of latch mechanism mounted on the cradle which normally locks the cradle-door in closed position. A carrier is presented in the cradle outside of the housing when the door opens. The cradle-door is manually closed, automatically actuating the latch mechanism to lock the cradle-door closed.Type: GrantFiled: August 15, 1980Date of Patent: October 5, 1982Assignee: Diebold IncorporatedInventor: Walter G.
