Abstract: An ophthalmic system (100) having an ophthalmic cassette (104) for operative engagement with an ophthalmic apparatus (102) is disclosed. The ophthalmic cassette (104) includes a cassette body (108) having a manifold (124) defining an inlet port (180) in fluid flow communication with first and second fluid pathways (120/122) which are in selective fluid flow communication with respective first and second storage chambers (116/118) such that fluid enters either the first storage chamber (116) or the second storage chamber (118). The ophthalmic apparatus (102) is operable to permit alternate fluid flow communication between the inlet port (108) and either the first storage chamber (116) or the second storage chamber (118) during operation of the ophthalmic system (100).

Abstract: A suspended work platform with an integrated rescue system and a method for rescuing a worker is used to quickly rescue workers from an elevated position. The system incorporates a work hoist and a rescue device cooperating with a platform rope. The work hoist is attached to the work platform. A worker changes the elevation of the work platform by operating a work input device of a work hoist control system. The rescue device cooperates with the platform rope and is attached above the work platform to a tie-off location. A rescuer operates the rescue device to perform a rescue of the worker when necessary. The rescue system may also include an independent fall arrest system having a descent control system with a fall arrest rope attached to the worker and to the tie-off location.

Abstract: A deflector element is provided, in order to improve temperature interface control with respect to directional solidification of a component casting. This deflector element is formed during the mould making process and is arranged to be positioned with respect to a part of a principal mould formation within which the final cast component is produced. The deflector element ensures a uniform temperature throughout the component cross-section relative to other parts of the component as it is solidified.

Abstract: An arrangement 10 for providing thermal energy to a portion 16 of a component 14 of a gas turbine engine while the component 14 is forming, wherein the component 14 is substantially elongate in a first direction 28 and the portion 16 extends from the component 14 in a second direction 38, substantially perpendicular to the first direction 28, and comprises a first surface area component 32 oriented in the first direction 28. The arrangement 10 further comprising an elongate member 18, connected to the portion 16 for heating the portion 16, wherein the elongate member 18 comprises a second surface area component 36, oriented in the second direction 38, wherein the second surface area component 36 of the elongate member 18 is greater than the first surface area component 32 of the portion 16.

Abstract: A turbine blade arrangement 100 comprises turbine blades 101, 102 which are secured in adjacent positions to a rotor disc 106 with a cavity 107 defined between root segments and platform segments 103, 104. Within the cavity 107 a flow deflector 112 is provided normally as an insert such that through a recessed portion 113 coolant flow B from a coolant path 111 is constrained to remain adjacent to a rim surface 105. By constraining the coolant flow B to remain adjacent to the surface 105 greater cooling efficiency is achieved. Inner surfaces of the deflector 102 may also be coated with low emissivity materials to reduce radiant heat flux transfer. Typically the flow deflector 112 supports a damper member 109 in association with the platform segments 103, 104.
