The air-lock is formed by an extensible metal bellows 9 having at its ends sealing flanges 10 and 11 which are provided with projections 18a and 19a, and are coupled to toggle levers 20a which are pivoted on a carriage which, by means of crank 29, may be moved along guide rails from the rest position of Fig. 1 to the sealing position of Fig. 2. Towards the end of the movement, the projections 18a and 19a encounter fixed surfaces 32 and 33 which retain the air-lock in a position aligned with the openings 4 and 7, while continued movement of the carriage, to a position determined by a projection 23a on the carriage, causes the toggle levers to pivot and thrust the sealing flanges against mating sealing surfaces. The sealing flanges are each provided with a threaded ring, to permit adjustment of their distance apart in the sealing position, and the interior space of the air-lock is normally filled with a removable filler plug 30, to reduce the loss of gas filling from the housing during operation of the lock. Reference is made to movement of the air-lock in a circular rather than a rectilinear path, and in a modified arrangement (Fig. 5, not shown) telescopic tubes rather than extensible bellows are employed. As described, the air-lock is employed for replacing the cathode 3 of an electron microscope;

Title: Improvements in or relating to means for the correlation of rotational and longitudinal movements in monochromators and other instruments
IPC: G01J3/12
Filed: 1931-03-07
Abstract: 374,429. Spectroscopic monochromators &c. HILGER, Ltd., A., TWYMAN, F., and PERRY, J. W., 24, Rochester Place, Camden Road, London. March 7, 1931, Nos. 7158 and 26906. [Class 97 (i).] In a monochromator or other instrument having a pivoted member or equivalent, the distance of the end of which from the pivot is required to bear a predetermined relation to the angular displacement of the member about the pivot, the said member is so dimensioned and pivoted that the locus of its end passes through three selected points lying on a straight line or deviating therefrom by specified small amounts. Preferably the said locus passes through the collinear points near the middle and ends of the desired range of movement. The Figures show the application of the invention to a double monochromator of the kind described in Specification 314,781, [Class 97 (i), Optical systems &c.]. Considering one half of this instrument, the pivoted member is here the light beam deviated by the prism 18 and passing through the rotating lens 2 and the end of this member is the focal point of the beam lying substantially on the axis of symmetry of the instrument, on which axis the mirror 15 is situated. By suitable selection of the angle of the prisms 18, 19, the axes of the first collimating lens 1 and the final imaging lens 4 can be arranged to remain parallel to each other and to the axis of symmetry over a wide range of wave-lengths. These lenses can then be mounted on a common carriage 7 movable along guides 8 and having a nut 9 engaging a rotatable adjusting-screw 10, the axis of which is in the plane of symmetry. An extension 12 of the screw 10 is also screw-threaded and is adapted to displace a carriage 13 on which is the mirror 15. The rotating lenses 2, 3 are carried by arms 16, 17 which are mounted on the carriage 13 in such a way as to be free to vary their inclination, these arms being rotatable about axes containing the second principal points of the lenses. The prisms 18, 19 are connected by gearing 20 to the lenses so as to turn at half the speed of the latter to ensure that rays reaching the mirror 15 have passed through the prism 18 under minimum deviation. Slight focusing errors may be corrected by a small adjustment of the carriage 7. A bell-crank lever 21, Fig. 3, pivoted to the nut 9 has at the end of its longer arm a roller 23 engaging a cam 24, and the short arm of the lever is connected by a link 25 to the carriage 7. Specification 363,264 is referred to.
