Abstract: The present invention relates to an improved tuning arrangement to linearise the sensitivity to frequency changes within a certain frequency range in response to tuner displacements relative to a resonator body. The tuning arrangement comprises a tuner and/or resonator having a non-uniform distribution of the effective dielectric permittivity along the axis of tuner displacement. The non-uniform distribution of the effective dielectric permittivity is realised by subdividing the tuner into an arbitrary number of sections, each of which distinguishable at least by their geometrical shape and the value and distribution of the dielectric coefficient ?r.

A second body portion extends along and at a distance from the first strip portion and is connected thereto by arcuate connection pieces, which extend from a first side edge of one of the body portions to an adjacent first side edge of the other body portion. First contact tongues are bent from the first side edge of the second body portion in direction towards the other body portion and ends between the planes of the two body portions. Second contact tongues are bent from the first side edge of the first body portion in direction towards the other body portion and ends outside the plane of the second body portion. Third contact tongues are bent from the other side edge of the first body portion in direction outwardly from the two body portions.

Abstract: A connector for connecting one end of an opto fibre to an optical component includes a retaining sleeve for a portion of the fibre near said end of the optical fibre, and a structure carrying the retaining sleeve and intended to be fixed with respect to the optical component. A spring acts between the retaining sleeve and the carrying structure for compensating for tolerances in the length direction of the retaining sleeve at connection to the optical component. The spring and the carrying structure are mutually shaped to admit introduction of the retaining sleeve together with the fibre held thereby, into the carrying structure prior to the spring sidewardly into the carrying structure.
