Abstract: An improved fuel transfer pump (10) is provided for relatively high flow transfer of fuel from one aircraft to another during an inflight refueling procedure, wherein the fuel transfer pump (10) includes a  jet-type scavenge pump (12) for evacuating residual fuel from a fuel line (14) or manifold (15). The scavenge pump (12) comprises a ventur i element (56) connected along a recirculation conduit (48) through which a small fuel flow is diverted from the high pressure discharge  side of the fuel transfer pump (10) for return to the fuel tank (20). The recirculation fuel flow induces a vacuum in a suction throat of th e venturi element (56), and this vacuum is coupled by a suction line (58) to evacuate residual fuel from the fuel line (14) or manifold (15)  to the fuel tank (20). A flow baffle (62) is mounted along the recirculation conduit (48) downstream from the venturi element (56) to ensur e flooding and priming of the scavenge pump (12).

Abstract: L'invention concerne un système émissif de présentation d'images visuelles. Le système émissif contient généralement des premières (90) électrodes déposées sur un substrat avec lequel elles sont en contact. Une ou plusieurs couches (40) tampons organiques conjuguées sont ensuite déposées sur les premières électrodes avec lesquelles elles sont en contact, et des deuxièmes (22) électrodes sont par la suite déposées sur les couches tampons organiques conjuguées. Les couches (40) tampons organiques conjuguées régulent un flux de courant entre les premières (90) électrodes et les deuxièmes (22) électrodes. Avant ou après le dépôt de chaque couche (40) tampon organique conjuguée, mais avant le dépôt des deuxièmes (22) électrodes, des dépôts (34, 36, 38) organiques conjugués sont imprimés par jet d'encre de sorte qu'ils soient en contact avec au moins une couche tampon organique conjuguée. Les dépôts (34, 36, 38) organiques conjugués favorisent la génération d'un indicateur lorsqu'une excitation de tension est appliquée à travers les premières (90) électrodes et les deuxièmes (22) électrodes. En fonction de la matière des dépôts (34, 36, 38) organiques conjugués, l'indicateur peut être à luminescence, à fluorescence, à conductivité ou analogue. On utilise une source de tension pour appliquer sélectivement l'excitation de tension à travers les premières (90) électrodes et les deuxièmes (22) électrodes.

Title: Safety brake assembly
Inventor: MITCHELL FRANK C
IPC: F16D63/00
Filed: 2001-07-13
Granted: 2008-02-12
Abstract: A safety brake assembly is disclosed comprising a housing movable on a vertical support, the housing attached to a carpet support arm, a pulley rotatably mounted on a shaft of the housing, a link having an inner end pivotally connected to the shaft and an outer end connected to a first end of a pivot bracket on the housing, a second end of the pivot bracket connected to a wedge-shaped member adjacent the pulley, and tensioning means connected intermediate the ends of the pivot bracket. In the event of cable failure, the upward pressure previously exerted on the pulley is released, causing a downward movement of the pulley and link, the movement transferred by means of the pivot bracket to cause upward movement of the wedge-shaped member which is forced up between the pulley and the vertical support, the resultant friction arresting further downward movement of the housing and carpet support arm.
