Abstract: A gas turbine engine includes a fan shaft diving a fan having fan blades. The gas turbine engine also includes a gear system including a sun gear surrounded by a plurality of intermediate gear, a carrier at least partially supporting said plurality of intermediate gears, and a ring gear surrounding said plurality of intermediate gears, wherein said sun gear is driven by a turbine. The gas turbine engine also includes a flexible coupling fixing said ring gear from rotation relative to an engine static structure and a lubricating system for said gear system. Said lubricating system includes a lubricant input, there being a stationary first bearing receiving lubricant from said lubricant input. Said bearing has an inner first race in which lubricant flows, and a second bearing for rotation within said first bearing. Said second bearing has a first opening in registration with said inner first race such that lubricant may flow from said inner first race through said first opening into a first conduit.

Abstract: A turbofan engine according to an example of the present disclosure includes, among other things, a fan, a compressor section, a turbine section including a fan drive turbine and a second turbine, an epicyclic gear system with a gear reduction, first and second bearings, and a fan drive shaft interconnecting the gear system and the fan. The fan drive turbine has a first exit area at a first exit point and is rotatable at a first speed. The second turbine has a second exit area at a second exit point and is rotatable at a second speed. A first performance quantity is defined as the product of the first speed squared and the first area. A second performance quantity is defined as the product of the second speed squared and the second area.

Abstract: A dispensing device for fluid medicine includes a housing having an opening leading to an interior and a plastic dropper bottle at least partially disposed in the interior through the opening. The bottle has a container holding fluid medicine to be dispensed and a nozzle with an aperture in fluid communication with the container. The device may include a tilt switch, a closure switch, and other electronics that improve patient compliance.

Abstract: A device for dispensing fluid medicine includes a housing having an opening leading to an interior, a first aperture, and a second aperture. The device also includes a plastic dropper bottle at least partially disposed in the interior through the opening. The bottle has a container holding fluid medicine to be dispensed and a nozzle with a third aperture in fluid communication with the container. The device further includes a drop counter switch disposed in the housing and a lever rotationally coupled to the housing. The lever has a first flange disposed in the first aperture for causing the bottle to dispense fluid through the third aperture. The lever also has a second flange disposed in the second aperture for operative engagement with the drop counter switch upon the first flange causing the bottle to dispense fluid through the third aperture.

Abstract: An improved device for dispensing fluid medicines from both physiological and compliance perspectives.

Abstract: A pharmaceutical product comprising an aqueous prostaglandin formulation and a polypropylene container are disclosed. Aqueous prostaglandin formulations are more stable in polypropylene containers than polyethylene containers.
