Title: Rocket engine
Inventor: STEPHENS RICHARD D
IPC: F02K9/64
Filed: 2000-03-10
Granted: 2008-05-06
Abstract: A rocket engine (10) comprises first (76) and second (142) rotary injectors for injecting respective fuel (20) and oxidizer (18) propellant components into a first combustion chamber (34), and the effluent (38) therefrom drives a turbine (40) that rotates the rotary injectors (76, 142). The mixture within the first combustion chamber (34) is preferably fuel-rich so as to reduce the associated combustion temperature, and the fuel-rich effluent mixes in a second combustion chamber (36) with additional oxidizer injected by a third rotary injector (182) so as to generate a high temperature effluent (214) suitable for propulsion. The rotary injectors (76, 142, 182) are adapted with associated rotary pressure traps (86, 146, 174) so as to isolate the low pressure propellant supply (22', 24') from the relatively high pressures in the respective combustion chambers (34, 36). A portion of the fuel-rich effluent from the first combustion chamber (34) is directed through an annular passage (198, 204) surrounding the combustion chambers (34, 36) to provide effusion cooling of a surface (218) of the second combustion chamber (36).

Abstract: A railway axle hub unit of the type comprising an axle box housing (1) for supporting a bearing, is provided with a sensor body (3, 9) containing sensors (4, 5) for detecting vibration in the vertical direction and the horizontal axial direction. The sensor body is mounted onto a stationary support element (2, 1, 15) rigidly secured to the bearing, preferably an annular sealing insert. The sensors perform monitoring of the operation condition of the hub unit by generating and transmitting signals indicative of the detected level of vibration to an electronic processing unit mounted on board of the railway vehicle or the train. The processing unit is capable of signalling in real time an impending failure and/or a damaged condition associated with the monitored hub unit.

Abstract: L'invention concerne un caoutchouc pour trayon, prévu pour un manchon de gobelet trayeur (40), sensiblement indéformable, destiné à former un gobelet trayeur à double espace, avec lequel pendant le processus de traite par aspiration, du lait est tiré d'un trayon par un vide de traite pendant le cycle d'aspiration et le trayon est massé pendant le cycle de relâchement. Le caoutchouc pour trayon comprend une partie de tête (12) sensiblement à symétrie de rotation par rapport à son axe longitudinal, ainsi qu'une partie de tige (14) reliée à la partie de tête (12) par une partie de jonction (22). La partie de tige (14) est souple, entoure le trayon et réagit aux variations alternées de pression pendant le cycle d'aspiration et le cycle de relâchement, par des variations de forme. La partie de tête (12) se présente sous forme de flexible annulaire (16) qui constitue une ouverture d'insertion (18) pour le trayon (Z). Pendant le cycle d'aspiration comme pendant le cycle de relâchement, la partie de tête assure l'étanchéité vis-à-vis du vide de traite et fait que le caoutchouc pour trayon adhère bien au trayon, sans serrer de manière excessive le trayon. Le flexible annulaire (16) se présente de manière que lorsque le trayon est inséré dans la partie de tige (14), une cavité annulaire (30) se trouve délimitée par le trayon, la partie de jonction (22) et le flexible annulaire (16). Pendant le cycle d'aspiration, la largeur intérieure du flexible annulaire est inférieure à celle de la zone de la partie de tige (14) prévue pour le trayon. Le flexible annulaire (16) présente une élasticité telle que sa largeur intérieure peut augmenter dans le sens radial vers l'extérieur au moment de l'introduction du trayon et que sa longueur axiale peut de ce fait être modulée.

Granted: 2012-03-20
Abstract: The present invention provides a transcoding architecture and a consumer set-top box with storage capability that is based on the transcoding architecture and capable of operating efficiently in an all-digital environment. In a preferred embodiment, a digital-VIDEO DEVICE employs an MPEG-2 compliant transcoder that includes a simplified cascaded decoder and encoder, and is capable of performing determinable bitrate re-encoding without conducting motion estimation. During recording, the decoder receives and processes a compressed source bitstream, producing a decoded bitstream that includes reconstructed video and preserved motion vectors. The encoder "re-encodes" the decoded bitstream using the preserved motion vectors and performs any applicable bitrate modifications. The re-encoded bitstream is then stored.
