Based on the flow and/or pressure of fluid from the inlet, the moveable or flexible member can reversibly move from a first position to a second position and/or from a second position to a first position. The first position is characterized by the moveable or flexible member being coupled to, proximate to, sealed to the aperture, and the second position is characterized by the moveable or flexible member being moved away from the aperture. | 2019-04-04 |
20190101227 | Tap Securing Device - A tap securing device comprising an elongate structure formed by a plurality of interconnected rings. The elongate structure further comprises first and second arms, the first arm located at a first end of the elongate structure and the second arm located at a second end of the elongate structure. The elongate structure is formed from a flexible resilient plastics material as a unitary moulding. Device is used to secure elements of a tap relative to each other and so prevent adjustment of the tap. This ensures the tap cannot be operated inadvertently by children. | 2019-04-04 |
20190101228 | HIGH PRESSURE ANTI-CAVITATION CAGE - A control valve has a cage disposed within a valve body adjacent a valve seat and proximate a valve plug to provide guidance for the valve plug. The cage includes a solid, unitary circumferential wall with inlet passages adjacent one of an inner surface or an outer surface and outlet passages adjacent the other of the inner and outer surface. An annular cavity is spaced apart from the inner and outer surfaces and is connected to the inlet passages. Intermediate passages are connected to the annular cavity and recovery plenums interconnect the intermediate passages and the outlet passages. The recovery plenums have cross-sectional areas that are larger than a cross-sectional areas of the intermediate and outlet passages. | 2019-04-04 |
20190101229 | CONTROL VALVE TRIM ASSEMBLY - A control valve has a trim assembly to condition the flow of fluid through the control valve and, in some applications, to provide guidance for a valve plug. The trim assembly has a lattice structure formed of a plurality of triply periodic surfaces that form a plurality of passages that extend between an inner surface of the circumferential wall and an outer surface of the circumferential wall. | 2019-04-04 |
20190101230 | APPARATUS AND METHODS FOR CONTROLLING THE MOVEMENT OF MATTER - Embodiments of apparatus for controlling the movement of matter, including but not limited to one-way fluid valves, are disclosed. The apparatus may include a transition nozzle, a funnel nozzle, and a reverse flow blocker arranged in series in a case. A counter-flow area may be disposed about the funnel nozzle. The apparatus may permit matter to flow in a first direction, and discourage or prevent flow in a direction reverse to the first direction. Control over the flow of matter may also enable the matter to be harvested, sorted, separated or combined with injected matter. | 2019-04-04 |
