Abstract: A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Abstract: A bearing lubrication system for turbine apparatus. Lubricating fluid stored in a pressurized oil reservoir is pumped by a main oil pump to the bearings. An oil cooler is provided immediately upstream of the pressurized reservoir to lower the temperature of the fluid stored therein and provided to the bearings. Oil returned from the bearings is drained to a nonpressurized oil collection chamber which supplies the suction of the main oil pump. An emergency gas system is included to insure an independent oil flow capacity in the event of interruption in power to, or failure of, the main oil pump.

Abstract: A hydraulic arrangement for turning the rotor shaft of an axial flow elastic fluid turbine rotor. The arrangement includes a variable speed hydraulic motor, the torque produced thereby being dependent upon the pressure of motive fluid supplied therethrough. The motor is connected through suitable coupling or clutch to the shaft. A plurality of sources of motive fluid each at a predetermined pressure range are connected to the motor. A flow control arrangement for selectively introducing motive fluid from each of the plurality of sources to the hydraulic motor to provide the desired torque output from the motor is provided.
