Abstract:
Methods of determining a first position at which a dispersed phase droplet wets a surface of a channel are provided herein. The methods include immersing the dispersed phase droplet in a continuous phase fluid, wherein the continuous phase fluid is immiscible with the dispersed phase droplet, subsequently flowing the dispersed phase droplet in the continuous phase through the channel at a dispersed phase droplet velocity, wherein the dispersed phase droplet is separated from the surface by a film of the continuous phase fluid having a film thickness, and reducing the film thickness to rupture the film at the first position, wherein the droplet wets the surface at the first position.
Abstract:
Eine Fluidbehandlungsanlage besteht aus mehreren nebeneinander angeordneten parallel betriebenen Schüttgutbetten (9). Das zu behandelnde Fluid durchströmt mindestens ein Schüttgutbett im Wesentlichen von unten nach oben, während das Schüttgut das Schüttgutbett oder mehrere Schüttgutbetten im Gegenstrom zum Fluid im Wesentlichen von oben nach unten durchwandert. Das wird bewirkt, indem am unteren Ende des Schüttgutbettes Schüttgutteilmengen abgezogen und am oberen Ende des Schüttgutbettes Schüttgutteilmengen dem Schüttgutbett aufgegeben werden. Mehrere der Schüttgutbetten sind durch einen gemeinsamen horizontalen Chargierkanal (11) miteinander verbunden. Zumindest ein, mit wahlweise verschließbaren Schüttgutauslässen, versehener Chargierwagen (19) ist durch den Chargierkanal (11) zwischen einer Chargierposition (28) und mehreren Schüttgutteilaufgabepositionen oberhalb der Schüttgutbetten verfahrbar. Unterhalb der Schüttgutauslässe und des Schüttgut-Absperrorgans (23) des Chargierwagens (19) sind Schüttgutdurchleitrohre (50) vorgesehen, deren Schüttgutauslassmündungen (51) auf Schüttgutkegeln (9K) eines darunter liegenden Schüttgutbettes (9) enden.
Abstract:
A modular mounting and connection or interconnection system for microfluidic devices (20) includes a plurality of end-butting compression-sealing fluid connectors or adapters (32), and one or more clamping structures (54, 56) each structured to hold one of the fluid connectors (32) in compression against a planar surface of a microfluidic device (20), and to press against the device, on another directly opposing planar surface thereof, either a contact pad (48) or another of the fluid connectors (32), with each clamping structure (54,56) including an individually moveable compression-providing element such as a compression screw (36) structured to provide a controlled amount of compression. The system desirably further includes one or more device frames (58) each structured so as to receive and hold a microfluidic device (20) with one or more of the clamping structures (54, 56) attached, the device frame (58) being structured to retain the device (20) and attached clamping structures (54, 56) by constraining only one or two of the clamping structures (54,56) in a manner such that no torsion or bending is applied to the device (20), and one or more system frames (70) structured so as to receive and hold a plurality of device frames (58) in proximity to each other in a three-dimensional array, such that volumes of desired fluid interconnections between devices (20) can be minimized.

Abstract:
In the treatment of water, an end piece is connected to a treatment cartridge housing and inserted into an appliance having bypass, inlet, and outlet valves. The end piece has an end piece wall from which an inlet fitting, outlet fitting, and protrusion extend. The inlet fittings, outlet fittings, protrusion, and cartridge housing each have a longitudinal axis. The inlet and outlet fittings have a cam surface for actuating the inlet and outlet valves, respectively. Further, the cam surfaces of the inlet and outlet fittings are angled and vectored in relation to their respective longitudinal axis. The protrusion is shaped for actuating the bypass valve.
Abstract:
A pump includes a quick connect interface (10) that attaches to any drink dispenser to allow the mounting of the pump without the necessity of connection devices such as threaded fittings and/or clamps. The quick connect interface includes a housing (11) having an inlet port (12) and an outlet port (13). Both the inlet and the outlet ports include a flow regulator that prevents the flow of product from the quick connect interface when the pump is removed. The housing also has a gas port (14) that connects to a gas source to deliver gas into the pump. The gas port includes a flow regulator that prevents the escape of gas from the source when the pump is removed. Additionally, the pump includes a counter that measures the volume of fluid pumped by the pump.
Abstract:
A wastewater disposal system for a building which recycles grey wastewater for irrigation. The system has interconnected wastewater pipes (20-29) containing two separate passageways (20a, 20b), one for reusable grey water and the other for sewer water, and three different types of T-fittings (30, 40, 50, 60) are used with the two passageway wastewater pipes (20-29), each T-fitting (30, 40, 50, 60) designed to interconnect two axially aligned wastewater pipes and having an offset opening to one of the wastewater passageways in the fitting, one type of T-fitting (30) designed to discharge sewer water into the sewer water passageway in the fitting, the second type (40) designed to discharge grey water into the grey water passageway (20a) of the fitting, and the third type (50, 60) designed to vent to atmosphere both passageways (20a, 20b) in the fitting. A fourth T-fitting (70) is designed to divert reusable grey water into a storage tank and channel sewer water into a sewer system.

Abstract:
The invention is directed to a multilayer microfluidic probe (MFP) head (100). The head typically comprises a first (110) and second (120) layers facing each others, and at least one tubing port (182), extending from the first layer (110). The first layer comprises one or more via (112), whereby fluid communication is enabled through the first layer towards the second layer. The second layer comprises at least one microchannel (124), relaying fluid communication to an aperture (122). Such a multilayered MFP head is easier to fabricate than heads made with unitary construction. In particular, a microchannel can advantageously be engraved a groove (124) at the level of the interface between the two layers. The MFP head can further be interfaced with tubing using e.g. a standard fitting for tubing port. The invention has substantial potential for e.g. patterning continuous and discontinuous patterns of biomolecules on surfaces as well as for direct processing of resist materials in a non- contact mode.
