20080272143 | Concentrate Level Sensing - A beverage system includes a pump that draws a set mount of a flavored concentrate into a mixing chamber through a conduit for mixing with water to form a beverage. A sensor detects when the amount of the flavored concentrate in the conduit or in the container is low or out. The sensor includes two wings each including a recessed surface that together defines a circular space. A portion of the conduit is received in the circular space. Each of the wings includes an ultrasonic portion that emits ultrasonic waves that are non-intrusive. When the amount of flavored concentrate in the conduit is low, air bubbles are generated in the flow along the conduit and/or a vacuum is created in the conduit to draw the conduit away from the recessed surface. The ultrasonic waves detect either of these two features, indicating that the amount of the flavored concentrate is low. | 11-06-2008 |
20080290114 | Drug Delivery Flow Controller - A drug delivery system for delivering a fluid to a desired location within a body that uses two control loops to control fluid flow: a first control loop in which a pressure source moves the fluid at an approximate rate, and a second control loop where a variable impedance mechanism more precisely controls the flow rate. After the fluid has moved through the chambers of these two control loops, a flow sensor measures the flow rate, sends the flow rate information to the control electronics, which then adjusts the pressure and impedance in a closed-loop manner to maintain a constant, desired flow rate. The drug delivery device may be used in portable or wearable mechanisms. | 11-27-2008 |
20090020556 | METERING ASSEMBLY AND METHOD OF DISPENSING FLUID - A metering assembly includes a fluidic chip and metering chambers. Selectable outlet valves communicate with each metering chamber to provide a discrete dispensed volume. The valves may be commonly controlled and may be formed as multi-level valves. The valves may be grouped into common substrate valve clusters. Purge channels communicate with the metering chambers and controlled purge valves allow reverse flow wash fluid to wash the metering chamber. Pressure ports are employed to actuate the valves. A method of dispensing a fluid from the fluidic chip includes a) selectively filling (or filling) the metering chambers with a selected fluid; and b) outputting (or selectively outputting) the fluid to output locations. The total output volume of fluid dispensed from each metering chamber may be accumulated. The process may be repeated until the accumulated volume equals the desired volume and may be repeated for another fluid from a plurality of different fluids. | 01-22-2009 |
20100051643 | MATERIAL METERING SYSTEM - A material metering system which is executed by way of multistage metering in which material drop amount supplied into a metering device from a material outlet of a hopper per unit time is stepwisely reduced in one batch metering as a stage of metering is changed to subsequent stage of metering, each time the mass value measured with the metering device reaches a supply mass switch value as set in advance for each stage of the metering, thereby performing one batch metering. The system comprises a memory in which a target metering time for the each stage of metering except for a first stage of metering is memorized, each of the target time including unstable metering time for drop amount of material whose drop amount per unit time after changed from prior stage of the metering is unstable; a metering time measuring means for measuring an actual metering time at the each stage of metering; and a set value correction means for correcting the supply mass switch value at each stage of the metering except for the first stage of metering based on the target metering time and the actual metering time after performing one batch metering, whereby the entire metering time for subsequent batch metering to be performed is more reduced than one batch metering performed. | 03-04-2010 |
20140014684 | WATER-CONDUCTING DOMESTIC APPLIANCE COMPRISING A DETERGENT DOSING SYSTEM WITH FILL LEVEL DETECTION - A water-conducting domestic appliance, in particular a domestic dishwasher, the water-conducting domestic appliance including a washing compartment for receiving items therein that are to be subjected to a washing cycle by the water-conducting domestic appliance; and a detergent dosing system, the detergent dosing system having a detergent dispenser with a receiving compartment, the receiving area for receiving at least one cartridge that is configured to hold at least one detergent, the detergent dosing system having the capability to store a quantity of detergent greater than a quantity needed for a single washing cycle and the detergent dosing system having an apparatus for detecting a fill level in at least one of the detergent dispenser and the at least one cartridge. | 01-16-2014 |
20140319172 | LIQUID REPLENISHMENT SYSTEM FOR A PRINTING APPARATUS FOR DEPOSITING A LIQUID COMPOSITION ON A BACKPLANE INCLUDING A DISPENSING VESSEL HAVING A CORRUGATED SECONDARY CONTAINER - A liquid replenishment system responsive to a volume control signal representative of the volume of liquid within a secondary container disposed within a dispensing vessel. The secondary container is fabricated of a material that is impervious to a driving fluid contained within the interior chamber of the dispensing vessel. The secondary container has a pleated sidewall forming of a collapsible bellows configuration with a freely movable end formed of a rigid planar base. A volume sensor is responsive to changes in position of the freely movable end within the chamber to generate a signal representative of the volume of liquid composition within the secondary container. | 10-30-2014 |
20150360930 | Vertical Storage Unit for Dispensing a Fuel Additive - This invention is directed to a vertical fluid storage system that has a lower container for containing fluid that includes a lower fill port defined in the top of the lower container. A routing hose routes fluid from the lower fill port to an upper container disposed above the lower container. The upper container includes an upper outlet connected to a gravity hose wherein the gravity hose is connected to a gravity port to direct fluid from the upper container to the lower container. An intake valve attached to the lower container and closes to prevent fluid from flowing from the upper container to the lower container when the amount of fluid in the lower container reaches a certain volume. | 12-17-2015 |
20160002019 | Device for protecting a liquid from oxidation - A device for protecting a liquid from oxidation inside a container includes a first element supplying the liquid inside the container, a second element supplying the liquid outside the container and a control unit. A pneumatic control system is configured to produce an overpressure inside the container and on the liquid when the liquid is supplied outside the container, such that, following a decrease in the volume of the liquid inside the container, the pneumatic control system increases its volume by an amount equal to the change in the volume of the liquid. The pneumatic control system includes a variable capacity tank and a pipe supplying and discharging a fluid for filling the tank. A system supplying and discharging the filling fluid is connected to the pipe and the supplying and discharging pipe communicates with the variable capacity tank through a connection placed inside the container at its lower end. | 01-07-2016 |
20160115011 | VERTICAL STORAGE UNIT FOR DISPENSING A FUEL ADDITIVE - This invention is a vertical fluid storage system with an upper container connected to a lower container. A fill port can be used to fill the upper container wherein the top fill hose is in fluid communications with the upper container. A first top valve in line with the top fill hose can be included to or controlling the flow rate of fluid into the upper container from the fill port. A top fluid level sensor can be included in the upper container for sensing the fluid level of the upper container. A gravity port included in the upper container can allow fluid to flow from the upper container to the lower container either during filling or when fluid is removed from the lower container. A dispensing port can be included in the lower container for dispending fluid from the lower container through gravity of a pump. | 04-28-2016 |
