Abstract: A system and method for shifting the relative phases of a PCM data frame and a network RBS frame by one or more symbols is disclosed. The method includes determining whether or not RBS is present (100). If RBS is present, the slots affected by RBS are identifed. Next it is determined what data slots, if any, are affected by encoding (102). The PCM data frame is shifted to the RBS constraint and the encoding constraint do not coincide at any particular data slot (104). For one particular PCM upstream modulation scheme, the digital modem adjusts the relative phases of the data-mode frame and network RBS frame such that a minimum number of trellis-modified symbols fall on network RBS affected slots. This information is transmitted to an analog modem (106).      The amount of shift can be conveyed to an analog modem in the same data sequence used to send upstream constellation sets and mapping parameters during an initial training sequence. The present invention improves the performance of any PCM modem that employs a data frame structure in which not all symbols are subject to the same constraints, for example, due to trellis coding.

Abstract: L'invention porte sur un appareil de chauffage d'un échantillon, par exemple un mélange de produits chimiques de réaction dont les propriétés diélectriques se modifient en cours d'échauffement, et en particulier sur un appareil de chauffage à microondes comportant: un générateur de microondes; un guide d'ondes dirigeant les microondes vers un applicateur; et un déflecteur en boucle fermé définissant un plan et présentant une fréquence de résonance propre, dont l'épaisseur est normale au susdit plan, pouvant tourner autour d'un axe au moins sensiblement parallèle audit plan, et placé dans le guide d'ondes de manière à former une cavité résonante avec l'échantillon et l'applicateur. On peut facilement régler les conditions de résonance de ladite cavité et le facteur de couplage du rayonnement du guide d'ondes avec la cavité en faisant tourner le déflecteur. Les conditions de résonance et le facteur de couplage se règlent en fonction des propriétés diélectriques de l'échantillon. On peut ainsi optimiser la quantité d'énergie absorbée et agir sur le processus d'échauffement de l'échantillon.

Title: Improved electron transfer system for well acidizing compositions and methods
Inventor: BREZINSKI MICHAEL M
IPC: C23F11/04
Filed: 2002-12-04
Granted: 2007-04-24
Abstract: An acidizing composition and a method of acidizing a hydrocarbon bearing subterranean formation in the presence of ferric ions are provided. The acidizing composition includes a mineral acid solution, an electron donor agent, a primary electron transfer agent and a secondary electron transfer agent. The primary electron transfer agent is a source of vanadium ions. The secondary electron transfer agent is a source of iodide ion or iodine. The electron donor agent and primary and secondary electron transfer agents function together to reduce ferric ion present in the mineral acid solution to ferrous ion which in turn prevents ferric hydroxide and/or free sulfur from precipitating out of the solution and reduces the formation of sludge in crude oil in the formation.

Abstract: A method and apparatus for supplying air to a ported rotary kiln involves the use of butterfly valves and a mechanical valve actuation system for introducing air into the kiln at axially and circumferentially spaced locations along the kiln length. The valve actuation system selectively and sequentially opens and closes the butterfly valves such that port air is introduced into the interior of the rotary kiln. The valve actuation system of the present invention is incorporated with a butterfly valve having a valve housing with an air passageway and including an air inlet and an air outlet, a valve disc rotatable within the housing to open and close the passageway, and a valve stem defining an axis of rotation and connected to the valve member for rotation therewith. The valve actuation system includes an assembly mounted on the valve stem to rotate the valve member between its open and closed positions. The valve actuator assembly includes an actuator base connected to the valve stem for rotation therewith, a lever assembly mounted coaxially with the actuator base and valve stem to freely rotate relative to the actuator base and valve stem, and a lost motion mechanism interconnecting the actuator base and the lever assembly for transferring torque from the lever assembly to the actuator base as the lever assembly rotates.

Abstract: The invention relates to a method for adjusting the degree of engagement of a tool (6, 7) disposed on the outer radius of at least one associated rotating roll (4, 5) with a web of material (1) running past it. The aim of the invention is to improve the method so that the degree of engagement of the tool can be adjusted without loss of time and without producing any scraps. To this end, for adjusting the degree of engagement of the tool (6, 7) with the web of material (1), first several different degrees of engagement are electronically defined by means of different peripheral speeds of the tool ( 6, 7) so as to be retrievable. Once an adjuster (13) is activated, the change t o another defined degree of engagement takes place during operation precisely when the tool (6, 7) engages with the web so that the new degree of engageme nt is carried out when the tool (6, 7) engages with the web of material (1) for the next time.

Granted: 2007-07-10
Abstract: A safety harness to be worn by a person includes a strap portion for exteding over a portion of the person's body to retain the person within the safety harness. At least a certion of the strap portion includes an outer shell of a high strength, flexible material. The otuer shell has a channel therein. The outer shell can, for example, have a tubular construction. The strap portion further includes a flexible inner member within the channel of the outer shell. The flexible inner member generally prevents the lateral edges of the strap portion from forming a sharp edge when under tension. In that regard, the lateral edges of the strap portion preferably remain blunted, arced or rounded rather than forming a sharp edge when the strap portion is under tension forces experiences in normal use of the safety harness. The rounded or blunted lateral edges of the strap portion of the present invetion reduce or eliminate the binding, pinching and chaffing common with currently available safety harness.
