222055000 | Constant weight, volume or pressure control by output | 10 |
20080223874 | Automated filling system for bulk liquid - An automated filling system to conduct a filling operation in which a bulk liquid transport vehicle is filled with a bulk liquid and quality assurance tests are performed by a gas analyzer. A programmable logic controller, employed to control the filling operation, is responsive to pressure within a fill line connected to the vehicle and is programmed to determine that there exists sufficient pressure within the vehicle to conduct an initial quality assurance test and that the fill line is properly connected to the fill line, without breaks in its flow integrity. The programmable logic controller also initiates and controls a pressurization process if there is not sufficient pressure to conduct the initial quality assurance test. | 09-18-2008 |
20090179044 | Fluid Delivery Device with Autocalibration - A micro fluid delivery device is particularly useful in medical applications. The device may be worn or carried by the user and may deliver drugs or other medicaments to the user or patient. The device has a control system that accepts input from the user and controls all aspects of operation of the device. The control system measures the output of the pump and adjusts the output of the pump to achieve the desired dosage rate and size. This eliminates differences from pump to pump that result from inevitable variations in the manufacturing of such small scale affordable devices. | 07-16-2009 |
20100147880 | BULK MORTAR SYSTEM - A system and apparatus for preparing bulk quantities of dry colorant or pigment for blending with mortar are described. The system mixes the three primary pigments of black, red and yellow to prepare a batch of the dry colorant having a particular color. The pigments or dry colorant are generally a powder of metal oxide crystals. The system includes pigment dispensers, wherein each pigment dispenser includes a tote that is in flowing communication with a slider valve. The slider valve is in flowing communication with a transition piece, and the transition piece is in flowing communication with a vibratory tray having an exit opening. A receptacle receives pigments from the exit opening of the vibratory trays. A control unit serially operates the vibratory trays to dispense the pigment from each tote. A scale measures the weight of the pigments in the receptacle. The scale is in operational communication with the control unit. | 06-17-2010 |
20120132672 | MATERIAL DISPENSING DEVICE, MATERIAL DISPENSING SYSTEM AND METHOD FOR CONTROLLED DISPENSING OF A MATERIAL AT AN OBJECT - A material dispensing device and a method for the controlled delivery to an object of a material from a material storage container in which the material is kept at an operating pressure so as to provide a material flow are described. The material dispensing device further comprises a flow meter and a pressure control element for controlling the operating pressure at the material in the material storage container on the basis of the dispensed amount of material measured or determined by means of the flow meter. A number of material dispensing devices may be combined into a single material dispensing system. | 05-31-2012 |
20140138405 | DISPENSING DEVICE - A dispensing device includes: a syringe; a first pump; a second pump; a first flowmeter; and a first control unit configured to correct a plurality of initial driving voltages for the first pump by calculating a first ratio of, with respect to a driving voltage for the first pump associated in advance with a target flow rate in a case where the syringe draws in a first fluid as the fluid, a driving voltage for the first pump when the first flowmeter measures a flow rate corresponding to the target flow rate in a case where the syringe draws in the first fluid, and multiplying, by the first ratio, the plurality of initial driving voltages for the first pump respectively associated in advance with a plurality of target flow rates in a case where the syringe draws in a second fluid as the fluid. | 05-22-2014 |
20140197198 | CARTRIDGE DISPENSER - A cartridge dispenser generally includes an actuator, cartridge carrier, a removable cartridge, a dispenser head, and a cartridge piston. A sensor is configured to sense data and provide feedback data for controlling the actuator. The dispenser head is a multi-piece assembly allowing removal of an outlet flow tube for maintenance purposes. The tube may be a resilient tube and pinch valves are provided for fluid flow control from the dispenser. | 07-17-2014 |
20140326748 | Fluid Dispenser and Method for Dispensing Fluids - A fluid dispenser comprising a fluid container and a metering unit is disclosed. The container comprises a fluid level sensor and the dispenser comprises a control unit configured to determine a parameter value representative for an amount of fluid in the container after refill on basis of a signal from the sensor. The sensor can for example be configured to generate a signal at a predefined fluid level (B, C), while the control unit is configured to calculate a fluid level on basis of an input value indicative of the fluid level (A) after refill, and a dispense value indicative of amounts of fluid dispensed since the latest refill. The control unit can be configured to compare the signalled predefined fluid level (B, C) with the calculated fluid level to generate a correction factor. | 11-06-2014 |
20150021358 | POWDER SUPPLY DEVICE AND POWDER SUPPLY METHOD - In a rapid load reduction mode for reducing a flow rate of powder to be supplied to the outside of a feed tank to a predetermined rate after a predetermined period of time, a controller sets an internal pressure control valve to an exhaust state and closes a powder discharge valve to a predetermined aperture, and as soon as the powder flow rate becomes smaller than a scheduled powder flow rate that is expected before elapse of the predetermined period of time, the controller controls at least one of the internal pressure control valve and the powder discharge valve so that the powder flow rate becomes the scheduled powder flow rate. | 01-22-2015 |
20150028055 | DISCHARGE APPARATUS AND DISCHARGE METHOD - A discharge apparatus | 01-29-2015 |
20150114990 | Feed Systems with Constant Pressures - The present invention discloses a feed system with a constant pressure. The feed system comprises a feed container which has a depressurize port mounted on its top, a intake port mounted at its side, and a feed port mounted on its bottom, contains a liquid material being a medicine or a liquid glue mixture; a intake structure which comprises a throttle pipeline and a throttle valve; a opening controller which connects to the throttle valve and the pressure sensor, for controlling the intake structure. The advantage of the feed system is to control the feed flow rate so as to maintain a constant during the feed process, particularly in the hybrid feed system. By steadily controlling the output flow rate, the mixed proportion is controlled to generate the product with the stable quality when two or more liquid materials must be mixed according to the specific proportion. | 04-30-2015 |
