| 20120291630 | MICROGRAVITY PASSIVE PHASE SEPARATOR - A passive phase separator separates and traps gases that may be present in a liquid flowing through a system. The phase separator includes an inlet in fluid communication with a first separator chamber and an outlet in fluid communication with a second separator chamber that is disposed annularly about the first separator chamber. Gas introduced into the first separator chamber is pushed downstream through the first separator chamber to a gas storage chamber. Once gas is trapped within the gas storage chamber it remains there for the entire operational life of the phase separator. | 11-22-2012 |
| 20130213232 | FLUID DEGASSING DEVICE AND METHOD FOR DEGASSING FLUIDS - The invention concerns a fluid degassing device for degassing fluids, in particular resins. The device has a fluid supply element for supply of the fluid and a fluid discharge element for discharge of the fluid. Between the supply element and the discharge element there is at least one structural element for breaking down bubbles in the fluid as it flows through the structural element. In addition or alternatively there may be provided at least one profile element, over which the fluid must flow. | 08-22-2013 |
| 20130327217 | DEFOAMING METHOD AND DEFOAMING APPARATUS - The objective of the present invention is to obtain an effective defoaming effect by directing a pulsed sound wave generated by shock caused by laser-induced breakdown to a liquid surface using an acoustic waveguide. A reflected wave of the pulsed sound wave generated by shock caused by laser-induced breakdown on an inner circumference face of the acoustic waveguide is directed to an opening part of the acoustic waveguide opposed to the liquid surface, and variations in periods of time in which the reflected wave in each travelling direction arrives at the opening part are reduced. | 12-12-2013 |
