Title: Rotors for gas turbine engines.
Inventor: KNOTT DAVID SYDNEY POULTENEY D
IPC: F01D11/00
Filed: 1993-04-27
Abstract: Separate wall members (20) bridge the space between adjacent blades (14) of a fan rotor (12) to define an inner wall of a flow annulus through the rotor (12). Each of the wall members (20) is adapted to be attached to the radially outer face (18) of a disc (16) and has opposing side faces (26) to which resilient seal strips (28) are bonded. The resilient seal strips (28) have flange portions (29) which are inclined radially inward along a curved edge (30) to produce undulations therein. The undulations enhance the flexibility of the flange portion (29) so that in operation as the fan rotor (12) rotates about a central axis of the engine (10) the flange portions (29) are deflected radially outwardly by centrifugal forces. The flange portions (29) are deflected into sealing contact with the adjacent fan blades (14) to seal the inner wall of the flow annulus.

Abstract: Dans un actionneur rotatif, il se produit des bruits dûs aux tourbillonnements qui se forment notamment avec l'utilisation de tubulures d'aspiration et de raccords de tubulures d'aspiration en plastique, bruits qu'il convient d'éviter. A cet effet, des surfaces de délimination (25) planes sont formées au niveau de l'orifice d'étranglement (13) et une surface de délimitation (26) plane est formée au niveau de l'orifice de sortie (14). En outre, dans la tubulure d'entrée, il existe des passages favorisant l'écoulement, ayant chacun une zone convexe et une zone concave (40, 41) d'un étranglement (24) tronconique et allant vers les surfaces de délimitation (25). Dans la tubulure de sortie (6), un passage favorisant l'écoulement qui comporte une zone convexe et concave (42, 43) va vers l'évasement (27) tronconique de la tubulure de sortie (6). L'actionneur rotatif est utilisé, en particulier, pour réguler la vitesse à vide de moteurs à combustion interne.

Abstract: Solid particles are transported from a first chamber (e.g. combustion chamber of a fluidized bed reactor) to an adjacent second chamber (e.g. a transporting and/or processing chamber) by providing a solid flow gas seal, a controllable solid flow valve, or both in a partition between the chambers. Transporting gas is introduced into the first chamber to transport solid particles as multiple solid flows from the first chamber to the second chamber. A number of narrow passages in the partition wall disposed one on top of the other, and having a height to length ratio of less than 0.5, less than 50 mm, act as the gas seal and controllable solid flow valve in the partition. The transporting gas may be introduced through the bottom of the first chamber, a side wall opposite to the partition wall, or both, and the partition wall may be lined with refractory adjacent the first chamber with passages in the refractory lining being made of combustible material which is burned away during heating of the refractory lining. The passages may also slant upwardly slightly from the first chamber to the second chamber, e.g. about 15 degrees.

Abstract: In a waste disposal unit sludge is incinerated to produce waste gases which contains mercury. The novelty is that the gases pass through a single or multi-stage washing system using an alkaline solution to remove acid gases, and that the mercury is subsequently separated in a second-stage washer using an aqueous acid solution. Pref. the second-stage washer uses chloride and an oxidant. A further washing stage reduces the HCl emissions value to less than 10 mg/m2 in the normal condition.

Abstract: A digital information receiver including a controller which selectively performs a signal strength based antenna selection mode and an error rate based antenna selection mode according to a speed of the vehicle. In the signal strength based antenna selection mode, an antenna is selected which receives a signal of the highest signal strength based on the output of signal strength detection circuit. In the error rate based antenna selection mode, an antenna is selected which receives a signal of the lowest error rate based on an error rate detection circuit. During one of the two antenna selection modes is being performed, if the signal strength or the error rate of received signal is not improved, the current antenna selection mode is switched to the other antenna selection mode.

Abstract: A baulkring-type synchronizer (18) includes cone clutch friction surfaces (24,48 and 26,50) and jaw clutch teeth (36b,28 and 36c,30) for frictionally synchronizing and positive connecting gears (14,16) to a shaft (12). A torque ring (63) is mounted in a shift sleeve (34) for limited rotation relative thereto and non-axial movement relative thereto. The ring defines self-energizing ramp surfaces (74a,74b,74c,74d), blocker surfaces (76a,76b,78a,78b), and reaction surfaces (76c,78c). The ring self-energizing ramp surfaces engage self-energizing ramp surfaces (70a,70b,72a,72b) defined on an outer circumference of a hub (32) affixed to the shaft. The ring blocker surfaces engage blocker surfaces (44a,44b,46a,46b) affixed to baulkrings (40,42). The ring reaction surfaces engage reaction surfaces (44c,44d,46c,46d) affixed to the baulkrings. Synchronizing torque produced by friction surfaces is partly reacted across the blocker surface, the remainder is reacted across the reaction surfaces, and the sum of the total synchronizing torque is reacted across the self-energizing ramp surfaces. A shift sleeve (34) is slidably splined to the hub (32) and is moved by an operator shift force (F<sub>o</sub>) and an additive force (F<sub>a</sub>) provided by the self-energizing ramp surfaces. Both forces (F<sub>o</sub> and F<sub>a</sub>) react against the blocker teeth to engage the friction surfaces.
