IPC: B61C9/52
Filed: 1991-01-07
Abstract: In a coupling for connecting axially staggered rotary components with a separable intermediate coupling member connected via a first pair of links to the driving half of the coupling and via a second pair of links to the driven half of the coupling, the intermediate coupling member (20) is made up of two arc-shaped intermediate half-members (76, 78). The intermediate half-members extend over more than 180 DEG , and hence each forms a lateral aperture (80). The intermediate half-members are arranged to be mutually offset by 180 DEG  so that the aperture (80) of each intermediate half-member (76, 78) is aligned with the closed central region of the other intermediate half-member (78, 76). In the end regions of each intermediate half-member (76, 78) there is a pair of radial straps (82, 84; 86, 88) staggered by 180 DEG , each of which is aligned with a corresponding strap (86, 88; 82, 84) of the other intermediate half-member (78, 76). In their central regions, moreover, each intermediate half-member (76, 78) has a pair of aligned straps at an axial distance from each other. Between the aligned straps of the first and second intermediate half-members (76, 78) there is a pivot for the links (26, 28) which pivot on one coupling half (34) and between the aligned straps (90, 92) there is a pivot for the links (16, 18) which pivot on the other coupling half (10).

Filed: 1991-01-31
Abstract: A system is described for slimming pulses which represent the data stored in a hard disk drive assembly. The pulse slimming system comprises a delay line (22) with the pulse applied in one polarity to a central tap (37). The same pulse is applied in the opposite polarity to taps (36, 38) along the delay line (22) on either side of the central tap (37). The pulses applied to either side of the central tap are controllably attenuated by amplifiers (17, 19) controlled by a microprocessor (30). The signal which is present at the output of the delay line is the sum of the original pulse with the attenuated pulses applied to either side of the central tap of the delay line subtracted from the leading and trailing edges of the pulse applied to the central tap. The amplifiers may be differential pairs including weighted or attenuation resistors. <IMAGE>
