Title: Constant-velocity universal joint
Inventor: GRUNDY CLIFFORD
IPC: F16D3/34
Filed: 1994-10-29
Abstract: A constant velocity universal joint has two half bodies 1 and a centre body 3 which houses a gearing cluster, each gear having at its outer extremity a control disc located in a bored insert 7 in each body half. As the halves of the joint assume an angle, the control discs rotate the gears inside their housings, forcing the plane in which the bushes 2 are located to maintain an angle of half that between the two bodies, thus achieving constant velocity. The half bodies 1 have orthogonally arranged jaws which slidingly engage grooves in bushes of the centre body 3. Facilities are provided by aligning the two halves of the joint, to exert pressure on the outer end of one of the centralising arms 6 or 7, to exit the opposite centralising arm plus its housing 4 and ultimately the insert 7, enabling easy and rapid dismantling of the joint for repair or fitting of new parts. <IMAGE>

Title: Holder for a compact disk
Inventor: FARRAR PETER ANTONY
IPC: G11B33/04
Filed: 1996-04-30
Abstract: A holder for a compact disk comprises a base portion (2) having two arms (1) resiliently cantilevered therefrom and extending radially inwards towards each other, the inner end of each arm having a projection (4A) and a contact portion (4). The projections (4A) are arranged to securely retain a compact disk by engaging on an outwardly facing surface thereof and the contact portions (4) of the arms (1) together form a button-like member (4) suitable for engagement by a finger tip. Depression of the button-like member (4) depresses the arms (1) so the projections (4A) move towards each other until their engagement with the outwardly facing surface of the compact disk is released. The contact portions (4) are arranged so that if a force is applied to the disk in the plane of the disk and perpendicular to the length of the arms (1), the majority of the force is transmitted by the disk to only one of the contact portions (4) so the possibility of the force acting on the button-like member (4) so as to release the disk is reduced.

Title: Multiwavelength optical amplifier evaluation apparatus
Inventor: MORI TOHRU
IPC: H01S3/067
Filed: 1997-02-06
Abstract: An apparatus for evaluating optical amplifiers comprises a plurality of light sources 1 -1 , 1 -2 , ...1 -n producing optical test signals at different wavelengths * small Greek lambda *1 , * small Greek lambda *2 ... * small Greek lambda *n . Each of these signals is intensity modulated at a different modulation frequency f 1 , f* small Greek eta *, ... f n . A light mixer 3 combines all the signals to form a wavelength multiplexed test signal which is then supplied to the optical amplifier under test 4. The output of the amplifier 4 is converted to an electric signal by a detector 5 then fed to a frequency discriminating and power detecting device 6. The frequency discriminating and power detecting device 6 measures the powers of the parts of the frequency spectrum of the electric signal corresponding to the modulation frequencies of the optical test signals. This device also determines a noise power measurement from the power of the electric signal at a frequency band which is apart from the modulation frequencies of the test signals. A computing section (not shown) then determines gains and noise figures for the optical amplifier wavelength by wavelength. Embodiments comprising a plurality of optical-to-electrical detectors and/or allowing polarisation sensitive measurements are also disclosed.
