20090146096 | APPARATUS AND METHODS TO ALIGN A CLOSURE MEMBER AND A VALVE STEM - Apparatus to align a closure member and valve stem for use with valves are described. An example valve includes a stem and a closure member having a first aperture to receive at least a portion of the stem. The example valve further includes a positioning member that has a first portion and a second portion. The first portion has a first cross-section and the second portion has a second cross-section that is greater than the first cross-section and an area between the first portion and the second portion forms a positioning surface to engage the first aperture of the closure member to align the stem and the closure member. A fastening member couples the stem to the closure member. | 06-11-2009 |
20130221259 | FLUID PRESSURE CONTROL DEVICE HAVING A THROTTLING ELEMENT SEAL - A fluid flow control device includes a body defining an inlet, an outlet, and a fluid flow path extending from the inlet to the outlet. A valve seat ring is coupled to the body and defines an orifice through which the fluid flow path passes. A cage is also coupled to the body and defines an interior bore, wherein the cage includes at least one passage through which the fluid flow path passes. A throttling element is sized for insertion into the cage interior bore and movable along an axis between open and closed positions. The throttling element defines a sealing surface oriented substantially parallel to the axis. A seal is positioned to engage the sealing surface when the throttling element is substantially in the closed position, thereby to restrict fluid flow through the valve seat ring orifice. | 08-29-2013 |

20090026395 | Apparatus to increase fluid flow in a valve - Apparatus to increase the fluid flow in a valve are disclosed. An example apparatus includes a valve body having a fluid passageway, a valve cage located in the passageway and including a wall having an outer surface and an inner surface defining a cage bore with an axis. The wall has at least one flow zone comprising a plurality of through openings, each through opening extending between the inner and outer surfaces to define an opening axis extending through the wall. The opening axis is disposed at a non-orthogonal angle with respect to a reference plane disposed orthogonal to the axis of the cage bore. A valve plug is axially slidable in the cage bore. | 01-29-2009 |

20140327737 | Method and Apparatus to Perform Optimal Visually-Weighed Quantization of Time-Varying Visual Sequences in Transform Space - Pure transform-based technologies, such as the DCT or wavelets, can leverage a mathematical model based on few or one parameters to generate the expected distribution of the transform components' energy, and generate ideal entropy removal configuration data continuously responsive to changes in video behavior. Construction of successive-refinement streams is supported by this technology, permitting response to changing channel conditions. Lossless compression is also supported by this process. The embodiment described herein uses a video correlation model to develop optimal entropy removal tables and optimal transmission sequence based on a combination of descriptive characteristics of the video source, enabling independent derivation of said optimal entropy removal tables and optimal transmission sequence in both encoder and decoder sides of the compression and playback process. | 11-06-2014 |
