    摘要: Described herein is a quasi-optic rotating joint (100) which allows circularly polarised radiation to be transmitted therethrough irrespective of the angle of rotation of the joint. The rotating joint (100) comprises a first quasi-optic lens (102) having a first axis (112), which is carried on an inner part (116, 118) of bearings (108, 110) and which shares first axis (112). An outer part (122) of bearing (110) carries a quasi-optic mirror (104) and a second quasi-optic lens (106). The second lens (106) has a second axis (114) which is orthogonal to the first axis (112) of the first lens (102) and which intersects at the mirror (104). A Gaussian beam waist is formed at the mirror (104) by the first lens (102) and the second lens (106) is matched to the reflection of the beam waist at the mirror (104). Circularly polarised Gaussian beams passing through the joint (100) suffer a phase shift of angle Ψ which increases at the same rate as the increase in angle of rotation of the joint (100). If the radiation returns through the joint (100) in the same hand of circular polarisation as it left, the overall phase shift is zero. If the hand of polarisation is swapped on return, the overall rotation dependent phase shift is 2Ψ.

    摘要: A fastening arrangement for fastening a storage container in a compartment of an aircraft galley comprises a latching mechanism including a latch and a first biasing mechanism, the first biasing mechanism being adapted to bias the latch into a latched position in a first operational state of the latching mechanism, such that the latch is adapted to interact with the storage container upon insertion of the storage container into the compartment of the aircraft galley so as to be moved from its latched position into an unlatched position against the biasing force applied to the latch by the first biasing mechanism, and such that the latch is adapted to be moved back into its latched position by the biasing force applied to the latch by the first biasing mechanism when the storage container has reached a predefined position in the compartment of the aircraft galley.
