    Abstract: A cermet piston 36 is positioned to reciprocate within a ceramic sleeve 58 of a cryogenic refrigerator 12. The sleeve 58 forms a very tight clearance seal 67 with the piston 36 yet is allowed to float within a large gap 66 between piston housing 35 and the sleeve. The gap 66 allows the sleeve 66 to compensate for misalignment or distortions of the piston housing 35. Elastic seals 68, 70 prevent gas blow-by between the working space 18 of the piston 36 and the piston's dead space 19. The piston is connected to a motor drive mechanism through connecting rod 44 and helium lubricated wrist pin 48.

    Abstract: A composite blade (26) comprises a three-dimensional arrangement of reinforcing fibers (58) and a matrix material (60) infiltrated around the three-dimensional arrangement of woven reinforcing fibers (60). The three-dimensional arrangement of woven reinforcing fibers (58) defines a plurality of cavities (56) within the aerofoil (28). The composite blade (26) comprises an aerofoil portion (38) and a root portion (36). The aerofoil portion (38) comprises a leading edge (44), a trailing edge (46), a concave pressure surface wall (50), a convex suction surface wall (52) and a tip (48). The aerofoil portion (36) comprises a plurality of webs (54) extending between, and being secured to, the concave pressure surface wall (50) and the convex suction surface wall (52) to produce a Warren girder structure. The three-dimensional arrangement of woven reinforcing fibers (58) are arranged to produce the concave pressure surface wall (50), the convex suction surface wall (52) and the plurality of webs (54). The matrix material (60) is an organic resin and the reinforcing fibers (58) comprise carbon fibers.

    Abstract: A refrigerant compressor having a drive shaft rotatable to cause compression of a refrigerant gas, and a drive power transmission unit for transmitting a drive power from an external drive power source to the drive shaft, the drive power transmission unit having a pulley freely rotatably mounted around the drive shaft, a power transmitting element fixed to the drive shaft, and a shock absorbent rubber element arranged between the pulley and the power transmitting element for providing a positive engagement between the rubber element and the pulley, and between the rubber element and the power transmitting element. The shock absorbent rubber element absorbs a change in a load torque applied to the compressor before the torque change is transmitted to the external drive power source via the pulley, and disengages from at least one of the pulley and the power transmitting element when an excessive load torque is applied to the compressor to interrupt transmission of the excessive load torque from the compressor to the external drive power source.
