The wall space and the mounting space for turbine bearings in the casing of an aircraft gas turbine are each supplied with cooling air via a separate pipe, a first cooling-air pipe opening into the wall space and a second cooling-air pipe extending through the wall space and opening in the mounting space. To ensure that the respective space continues to be supplied with cooling air even if one of the two pipes breaks, the cooling-air pipe extending through the wall space and opening into the mounting space has air overflow openings in the region of the wall space.
摘要:
Water vapor released by evaporation in a cooling tower, is conducted through an enclosure to the upper inlet end of a vertical conduit extending into the body of water stored in the cooling tower. The water vapor downflowing through the vertical conduit under vacuum conditions is condensed by cooling sprays of water drawn by pumps from the bottom of the cooling tower.
摘要:
A long or triple jump foul detector system is disclosed which very accurately detects a foul by an athlete when a portion of an athlete's shoe crosses over a foul line when beginning the jump. A laser beam is emitted parallel to and directly above the foul line. A laser beam detector detects interruption of the laser beam by the athlete's shoe and a foul detector provides a foul indication. An audible foul indication is delayed so as not to interfere with the athlete's jump. Also, the system may provide additional detection of an athlete's foot crossing a training line positioned in front of the foul line. Furthermore, the system distinguishes between a relatively quick interruption of the beam caused by the athlete's shoe when jumping, and a relatively slow interruption of the beam which may result such as by a judge placing his or her hand in the beam when measuring a jump. The system is equally well adaptable to either indoor or outdoor long or triple jump competition, and includes convenient set-up procedures which ensure accuracy. The system also automatically compensates for varying light conditions and is effective in bright sunlight. When a low battery voltage condition arises, the system automatically alerts the operator. A micro-processor is employed for rapid and accurate control of the various functions performed by the system.

A multi-functional handheld hygienic device with a J-shaped nozzle and attachment options for alternate use externally on either the genital area as a bidet or the rectal area as a wash and for use internally in the genital area as a douche and the rectal area as an enema. A temperature controlled water tank or water diverter attached to a combined hot and cold faucet supplies temperature controlled water to the nozzle.
