Abstract:
Jetting devices and methods for dispensing a fluid material from a fluid supply. A jetting device (10) includes a fluid module (12) configured to be coupled with the fluid supply (16) and to dispense the fluid material. The fluid module (12) includes a valve seat (64) and a valve element (62) configured to move relative to the valve seat (64) over a stroke length, and a valve stop (80) configured to position the valve element (62) relative to the valve seat (64) for determining the stroke length. The jetting device (10) further includes a drive module (14) configured to actuate the fluid module (12) and includes a drive pin (102) configured to move the valve element (62) toward the valve seat (64). The drive pin (102) is configured to be rotated to cause rotation of the valve stop (80) for adjustment of the stroke length. The drive pin (102) may be rotated by a rotation device (110) comprising a motor.
Abstract:
Fluid flow control devices comprise a cylindrical body extending along a longitudinal axis and having a sidewall. The cylindrical body has a first channel extending longitudinally along the sidewall and a second channel extending longitudinally along the sidewall. At least a portion of one of the at least one first channel and the at least one second channel extends longitudinally at an oblique angle with respect to the longitudinal axis to form a pattern of channels for improving the flow characteristics of a fluid through the channels.

Abstract:
Method for cleaning the conveying pipe of a pneumatic material conveying system, such as of a waste conveying system, and/or for conveying material that is in the piping, in which method at least one cleaning means (1) is fed into a conveying pipe, and a pressure difference is achieved in the pipe and under the influence of the pressure difference the cleaning means is brought to move for cleaning the pipe, and/or for conveying material, in the conveying pipe section intended to be cleaned. In the method a cleaning means (1) or a combination of a number of cleaning means (1, 1') is moved in the conveying piping (100, 101), and that the cleaning means (1) or combination of a number of cleaning means (1, 1') is connected to a transmission means (2), with which the movement of the cleaning means (1) or combination of a number of cleaning means (1, 1') in the conveying piping is limited or guided. The object of the invention is also a cleaning apparatus and a system.
Abstract:
A disc pump valve (10) for controlling the flow of fluid through a disc pump includes a first plate (16) having first plate apertures (20) and a second plate (14) having second plate apertures (18) both extending generally perpendicular through the first plate (16) and the second plate (14), respectively. The second plate apertures (18) are substantially offset from the first plate apertures (20). The disc pump valve (10) also includes a sidewall (11) disposed between the first plate (16) and second plate (14). A valve flap (17) is disposed and moveable between the first plate (16) and second plate (14). The valve flap (17) includes flap apertures (22) substantially offset from the first plate apertures (20) and substantially aligned with the second plate apertures (18), and low-mass areas (21). The low-mass areas (21) are offset from the first plate apertures (20) and second plate apertures (18). The valve flap (17) moves between the first plate (16) and second plate (14) in response to a change in direction of differential pressure of the fluid outside the disc pump valve (10).
Abstract:
A fuel line assembly for an aircraft comprises a ferrule assembly comprising a ferrule affixed to an isolation tube, which may be directly affixed to a fuel tube or affixed to an extension tube, which in turn, is affixed to the fuel tube. The ferrule assembly provides electrostatic discharge protection and lightning protection as the isolation tube maintains a separation distance from the ferrule and fuel tube, both of which are made from metal. The isolation tube is made from a dielectric material, but which may have conductive particles added to aid in the dissipation of an electrostatic charge. The electrical resistance through the isolation tube has a lower limit to arrest the flow of the induced lightning current through the assembly. The amount of lightning protection afforded can be configured. The ferrule assembly components may be affixed by using thermo-welding, adhesive, or mechanical pressure.
Abstract:
High range activated clotting time (HR-ACT) tests detect blood clotting time in blood samples which have high levels of heparin. Reagents such as calcium chloride and kaolin within the test apparatus trigger clotting. Physical separation of the reagents from each other prevents interaction between them before the test sample introduction. In one embodiment, to improve dry kaolin re-suspension, kaolin may be suspended in water rather than buffered saline before being dispensed into the test chamber. The combination of removing the buffered saline and the calcium chloride from the kaolin suspension enables clot detection in blood samples containing 5-6 u/ml of heparin.
Abstract:
A riser system for transporting slurry from the seabed to the sea surface. The riser system comprises a first and second riser, a slurry pump system (17) to transport slurry up one of the risers, and a waste water pump system (107) to return waste water down one of the risers. The slurry pump system and the waste water pump system are selectively connectable to each of the risers to allow each riser to be either a slurry riser (1) or a waste water riser (2). With this arrangement, if a slurry riser develops a leak partway along its length the waste water riser can be converted into a slurry riser such that operation can continue.
Abstract:
One aspect of the technology relates to a method comprising the steps of: moving a frame movably holding at least one hollow bore pin having a liquid dispensing tip, such that the liquid dispensing tip of the at least one hollow bore pin moves into a respective well of a set of target wells, and the liquid dispensing tip makes contact with a bottom surface of the respective well; continuing to move the frame after the liquid dispensing tip makes contact, such that the at least one hollow bore pin moves to a particular position (e.g., vertical position) within a range of positions (e.g., vertical positions) relative to and permitted by the frame.
Abstract:
The invention provides for fluidic connections to be established between tubes, ports, fluidic components and fluidic devices. The leak-tight connections are formed through controlled, compressive forces and can be used for both low and high pressure applications.
