摘要： An arrangement for centering, aligning and retaining a rigid disc such as a rapidly rotating video disc in an operating position, comprising a centering device mounted on a drive spindle, which device cooperates with a central disc hole in the disc, comprising a disc aligner mounted on the drive spindle for aligning the disc in a plane perpendicular to the axis of rotation of the drive spindle in the operating position of said disc, and comprising a disc loader for loading the disc towards the disc aligner. The disc aligner is rigidly connected to the drive spindle and the centering device comprises a plurality of resilient centering members which cooperate with the wall of the disc hole and which are radially movable between a rest position and an operating position which is situated nearer the axis of rotation of the drive spindle.

摘要： The invention relates to a method and apparatus for pressforming an article of a thermoplastic material. In accordance with the method a charge of molten material is deposited in a mould (14) and the central axis of a pressing plunger (18) and the mould (14) are aligned, after high a pressing operation is performed, the alignment being interrupted just before the end of the pressing operation. The apparatus comprises a frame (2), a mould (14) and a plunger (18), which plunger (18) is connected to a guide mechanism (22) which is movably connected to the frame (2) and which can be coupled rigidly to the mould (14) by coupling means (52).

摘要： An optical telecommunication element comprising one or more undulating optical fibers in which each fiber extends along a sheath. Each fiber is in the form of a helix or quasihelix which has an alternating left-handed and right-handed pitch. The fibers are fixed on the inner wall of the sheath at points of pitch reversal, the fibers preferably being fixed by glued joints.

摘要： An optical fiber cable comprising a cylindrical body and optical fibers which are located, and periodically fixed, in respective grooves in the body. The grooves extend along the length of the body in a helical manner, which may periodically change its sense of rotation. The grooves are either in the surface of the body or in the inner surface of a jacket surrounding the body. The fibers may be fixed after every full turn by means of a wire located in a longitudinal groove which crosses the grooves in which the fibers are fixed. The fibers may alternatively be periodically fixed by means of a longitudinally extending adhesive strip. The whole assembly may be provided with a layer of wound tape and a jacket.
