20080245416 | Device and Method for Distribution of Two Mutually Immiscible Liquids - The invention relates to a device and a method for distributing two liquids that cannot be mixed with each other for mass transfer and heat exchange columns, comprising at least one distributor channel or a distributor channel arrangement, the distributor channel being fed one or more liquids in different phases via at least one inflow from a collecting device arranged above said distributor channel, and said distributor channel having overflow and/or outflow openings for the distribution of the liquids. The device according to the invention is distinguished by the fact that the distributor channel has at least one internal means for the phase separation of the liquid and that separate outflow and/or overflow openings are provided for each of the phases to be separated, the cross section and/or elevation of which openings are arranged in dependence on the physical properties of the liquids in such a way that a homogeneous distribution of the liquids on the basis of predetermined phase components is achieved. | 10-09-2008 |

20100084022 | ADDITIVE DISPENSING SYSTEM AND METHOD - A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, and a three-way valve that passively arms and dis-arms the system. The precise dispensing of liquid by a calibrated dispensing vessel into the adjacent reservoir is accomplished entirely through the management and arrangement of hydrostatic pressure creating a liquid piston generated by the addition of liquid to the adjacent reservoir and its subsequent application to the liquid in the calibrated vertical column that displaces the calibrated volume of liquid into the reservoir at the same rate that liquid is added to the reservoir. | 04-08-2010 |
20110253225 | METHOD FOR CONTROLLING A GAS FLOW BETWEEN A PLURALITY OF GAS STREAMS - The present invention relates to a method and apparatus for controlling a gas flow through a conjunction between one or more incoming streams and one or more outgoing streams through a conjunction. The method uses a biased mass flow imbalance value obtained by comparing the aggregate of incoming mass flow measurement value(s) with the aggregate of outgoing mass flow measurement value(s) and adding a bias component to provide the biased mass flow imbalance value. The flow of at least one of the incoming and outgoing streams ( | 10-20-2011 |
20120080094 | METHOD AND DEVICE FOR FEEDING A PRESETTABLE MEASUREMENT QUANTITY OF A SAMPLE LIQUID - A method and device for feeding a presettable measurement quantity of a sample liquid from a liquid reservoir via a feed line through a switching valve into a temporary store in order subsequently, after actuation of the switching valve, to feed the sample liquid to an analytical measuring instrument where the sample liquid is conveyed into the temporary store until further conveying of the sample liquid is terminated and the switching valve is actuated by evaluation of a characteristic quantity, wherein a flow rate of the sample liquid is determined at a time at which a first proportion of the sample liquid has already flowed through the switching valve, and the switching valve is actuated as a function of the flow rate determined and a switching delay determined in advance. | 04-05-2012 |
20130213485 | TOOLS AND METHODS FOR PROCESSING MICROELECTRONIC WORKPIECES USING PROCESS CHAMBER DESIGNS THAT EASILY TRANSITION BETWEEN OPEN AND CLOSED MODES OF OPERATION - Strategies for tool designs and their uses wherein the tools can operate in either closed or open modes of operation. The tools easily transition between open and closed modes on demand. According to one general strategy, environmentally controlled pathway(s) couple the ambient to one or more process chambers. Air amplification capabilities upstream from the process chamber(s) allow substantial flows of air to be introduced into the process chamber(s) on demand. Alternatively, the fluid pathways are easily closed, such as by simple valve actuation, to block egress to the ambient through these pathways. Alternative flows of nonambient fluids can then be introduced into the process chamber(s) via pathways that are at least partially in common with the pathways used for ambient air introduction. In other strategies, gap(s) between moveable components are sealed at least with flowing gas curtains rather than by relying only upon direct physical contact for sealing. | 08-22-2013 |
20140048141 | FLOW BALANCING IN GAS DISTRIBUTION NETWORKS - Flow distribution networks that supply process gas to two or more stations in a multi-station deposition chamber. Each flow distribution network includes an inlet and flow distribution lines for carrying process gas to the stations. The flow distribution lines include a branch point downstream from the inlet and two or more branches downstream from the branch point. Each branch supplies a station. The flow distribution network also includes highly variable flow elements in each branch. Restrictive components are placed downstream from the variable control elements in each branch. These restrictive components are nominally identical and designed to shift the bulk of the pressure drop away from the variable flow components to improve flow balancing while not unduly increasing inlet pressure. In some cases, the load shifting allows the more variable flow components to operate in the unchoked flow regime. | 02-20-2014 |
20140366949 | APPARATUS AND METHOD FOR FLUID CONTROL - A multi-phase separation flow management system includes a housing with an inlet, a first outlet and a second outlet and in which a movable element is mounted. The movable element has a first passageway with an inlet and an outlet and a second passageway having an inlet and an outlet, and are disposed in the element so that the inlets of the first and second passageways are adjacent one another and the outlets of the first and second passageways are spaced apart from one another. The inlets are disposed adjacent a housing inlet, the first passageway outlet is disposed adjacent a first housing outlet and the second passageway outlet is disposed adjacent a second housing outlet. | 12-18-2014 |
20150059859 | APPARATUS FOR DIVIDING AND SUPPLYING GAS AND METHOD FOR DIVIDING AND SUPPLYING GAS - An apparatus for dividing and supplying gas is provided with a flow rate control device, a plurality of divided flow passages of gas flowing from the flow rate control device, thermal-type mass flow sensors disposed to the divided flow passages, electrically-operated valves disposed on a downstream side of the thermal-type mass flow sensors, controllers that control the electrically-operated valves, and a flow ratio setting calculator that calculates a total flow rate, then calculates flow rates of the divided flow passages, and then inputs the calculated flow rates as set flow rates to each controllers. One of the divided flow passages with the highest set flow rate is put in an uncontrolled state, and opening degree for each of the rest divided flow passages is controlled, and then feedback control of the divided flow rate of each of the divided flow passages is implemented by each of the controllers. | 03-05-2015 |
