Abstract: A shipping system for a medical device, such as implantable lens for an eye, is provided that may be reconfigured from a shipping mode into an injection mode without manually handling the contained lens or other device. Upon manufacture, a lens may be placed within the system assembly in the shipping configuration. While in the shipping configuration, the lens is kept in its desired shape and within a selected environment. Upon arrival at the destination, the user may attach fittings for injection of the device into a body. The process of changing from the shipping to the injection mode deforms the device into a shape suitable for injection. A new assembly for insertion of a medical device utilizing the shipping systems is also disclosed which includes a resilient ring through which a plunger extends to provide digital feedback as the medical device is inserted.

Abstract: The method controls gas flow in an axial flow compressor in which the flow at one or more chosen station in the direction of flow through the compressor is sensed at a series of circumferentially spaced positions. Flow variations above a predetermined limit are evaluated to initiate a response if a disturbance above a predetermined acceptable level is detected. When such a disturbance is detected, higher pressure gas bled from downstream is injected at a station to supplement the main gas flow. An incipient rotating stall cell will appear as a variation occurring sequentially at the circumferentially spaced positions. By responding to such a condition with a pressure injection, it is found possible to suppress both rotating stall and surge conditions in the compressor before this disturbance develops fully. The same method can be arranged to counter steady state distortion.

Abstract: A hydraulic seal is formed in the annular space 16 between two coaxial drive shafts 12 and 14. The seal is assembled with the two shafts in situ. An annular resilient seal member 30, which has an outer diameter which is larger than the inner diameter of the outer shaft 12, is deformed so that it can be passed through the annular space 16. The resilient seal member 30 is positioned in a channel 18 in the inner surface of the outer shaft 12. Once in the channel 18 the resilient seal member 30 returns to its original shape. The resilient seal member 30 is located between a pair of annular flanges 22 and 26 on the end of a pair of elongate members 20 and 24 of annular cross-section. The resilient seal member 30 protrudes into the channel 18 so that in operation it is partially immersed in a fluid 32 in the channel 18 to form the hydraulic seal.

Abstract: A variable pitch propeller module includes first and second multi-bladed propellers arranged to be driven in opposite rotational directions by a reduction gear mechanism, via shafts. First and second drums are rotatably mounted on the hubs of the first and second propellers and the drums are arranged to rotate the blades of the propellers. A hydraulic motor is mounted coaxially on and rotates with the second propeller, the hydraulic motor being arranged to drive the drums by via a pitch change gear assembly. A hydraulic fluid feed tube extends coaxially through the reduction gear mechanism and both propellers to supply hydraulic fluid to the hydraulic motor. An annular sleeve is positioned coaxially on the tube. The hydraulic fluid feed tube has passages and the sleeve has passages which are aligned to allow hydraulic fluid to flow to the hydraulic motor to vary the pitch of both blades. The feed tube and sleeve are moved axially to control the flow of hydraulic fluid to the hydraulic motor.
