Abstract: A butterfly valve noise suppressor (10) is provided for reducing the noise generated by a gas flow passing through an open butterfly valve having a dis c (16) pivotally mounted in a valve housing (12) for rotation about a transver se axis between an open and a closed position thereof. The noise suppressor (20 ) includes a plurality of flat and perforated baffle plates (22) arranged in a cruciform configuration, mounted in a flow path immediately downstream of th e pivotal disc, axially extending and thereby dividing the downstream flow pat h into four axial and quadrant cross-sectional segments (24). The gas flow passing the edge of the pivotal disc in the valve generates a flow turbulenc e to form an unsteady large wake downstream of the valve. This unsteady wake i s the source of noise. The cruciform baffle plates (21) permit the gas flow to pass therethrough without obstruction thereto, while allowing the turbulence to communicate laterally through the perforation (26), thereby dissipating t he wake unsteadiness to reduce noise. The butterfly valve noise suppressor according to the present invention provides a better acoustic result compare d to a muffler used in a conventional butterfly valve, and is lighter, durable , simpler and more economical to manufacture.

A polymeric, coaxial transfer line is utilized where a first portion of the cryogenic fluid flows through the inner tube while a second portion flows through an annulus between the inner tube and outer tube which annulus is at a lower pressure than the inside tube. In one embodiment, the inner tube is substantially non-porous and the transfer line is preceded by a flow control means to distribute at least part of the first and second portions of the cryogenic fluid to the inner tube and annulus respectively. In a second embodiment, the inner tube is porous with respect to both gas permeation and liquid permeation such that both a gaseous part and a liquid part of the fir st portion permeates into the annulus to form at least a part of the second portion.

Abstract: A turbine blade applicable to a gas turbine has a turbine blade body having film cooling holes, the interior space of which is partitioned into two cavities by a rib. Hollow inserts each having impingement holes are respectively arranged in the cavities to form cooling spaces therebetween. Communication is ensured between the cavities by a communication means, so that the impingement cooling is interrupted with respect to the prescribed side having a good heat transmission in the turbine blade body. A partition wall is further arranged between the rib and the insert arranged in the trailing-edge side, thus providing a separation between the cooling spaces respectively arranged in the rear side and front side. Thus, it is possible to noticeably reduce the amount of cooling air in the turbine blade body; and it is possible to reduce temperature differences entirely over the turbine blade body as small as possible.

Abstract: An optical system design for measuring the velocity of fluids flowing through pipes or other conduits is disclosed. The optical system is comprised of a means for delivering two beams through a window in the wall of the pipe, focused to two points aligned along an axis of the pipe and separated by a known distance, and means for detecting light that is scattered by particles carried in the fluid stream through a second window, that is disposed on the opposite side of the pipe. By measuring the time delay between detected signals, the velocity of the fluid can be determined. The delivered light beams are focused in a shallow cone of light and are blocked by an obstruction disposed behind the second window. The scattered light passes through an aperture behind the second window that surrounds the obscuration, and is focused on to a detector surface

Abstract: A computer device (110) such as a mobile phone or PDA for example, is able to access an application program or command, based upon selection of corresponding sequences of symbols (130). Such symbols (130) can be polysemous in nature and thus be associated with a plurality of different meanings depending upon other symbols (130) sequenced therewith. By utilizing polysemous symbols, a relatively large number of sequences can be developed and associated with programs and/or commands of the computer device (110), with only a relatively small number of symbols (130) displayed. In devices such as PDAs and mobile phone where display space (120) is a premium, such access to commands and programs can be invaluable.

Abstract: Apparatus, systems and methods for receiving one or more input signals and providing output signals in various video, audio, data and mixed formats are described. One or more input processors receive the input signals. Each of the input processors provides one or more packetized signals corresponding to one or more of the input signals received at the input processor. Each output processor can receive one or more packetized signals and generates one or more output signals. The output signals correspond to one or more the input signals, additional locally generated signals or data relating to the signals or any combination of such signals. The input processor can incorporate signal processors to process the input signals to provide versions of the input signals or to generate data about the input signals and for other purposes. The output processor may similarly incorporate signal processor to process signal received as part of the packetized signal. Use of a packet router according to the invention allows signals encoded with one set of packetized signals to be recombined to provide additional packetized signals incorporating the same or different combinations of signals.

Title: Elevating operator cabin for coiled tubing injector
Inventor: CAIN TROY D
IPC: B66F7/02
Filed: 2004-05-05
Granted: 2008-02-12
Abstract: A transportable, elevating operator cabin for use in connection with controlling coiled tubing injection equipment comprises a cabin including control elements; an elongated flexible element of fixed length extending under the cabin, between two, elevated points on adjacent structures located on opposite sides of the cabin; and a take-up mechanism for shortening the length of the flexible element between the two, elevated points. The take-up mechanism is mounted in a fixed position relative to the cabin so that operation of the take-up mechanism results in elevating of the cabin with respect to the adjacent structures. The cabin may be raised to a distance roughly equal to the height of the cabin while maintaining a compact design not much larger than the cabin itself that is suitable for transport, and the arrangement avoids mechanical complexity and costs associated with using other types of lifting mechanisms.

Title: Flow control in network devices
Inventor: MANNAL SOENKE
IPC: H04L12/56
Filed: 2003-10-30
Granted: 2009-04-21
Abstract: Methods and apparatus are provided for controlling flow rates of a plurality of data packet flows into a queue 4 corresponding to a resource 3 of a network device 1. The flows comprise a set 7 of non-responsive flows, and a set 8 of other flows which may comprise responsive flows and/or flows whose responsiveness is unknown. The flow rates are managed in accordance with a queue management scheme such that adjustments are made to each flow rate in dependence on excess bandwidth in the resource, the amounts of the adjustments being dependent on one or more adjustment parameters for each flow. An error signal is generated based on the deviation from a desired allocation ratio of the ratio of the total flow rates into the queue 4 for the sets of flows 7, 8. At least one adjustment parameter for at least one flow is then varied in dependence on the error signal in such a manner as to reduce the aforementioned deviation. A closed-loop control scheme thus operates in conjunction with the underlying queue management scheme to promote fair bandwidth allocation even in the presence of a mix of responsive and non-responsive flows.
