Inventor: ABBOTT RANDLE LESLIE
IPC: F16H37/02
Filed: 1979-01-17
Abstract: The invention is concerned with a continuously variable transmission mechanism which incorporates a variator (10) and an epicyclic gearset (18, 19, 20). Several brakes and/or clutches (17, 28, 29, 25, 27) are arranged for selectively coupling together or holding stationary various parts of the mechanism to provide forward and reverse transmission ranges within which the overall transmission ratio can be varied by the variator (10). In a first mode of operation the drive is through the variator (10), the epicyclic gearset (18, 19, 20) acting as a reduction gearing and a further reduction gearing (22, 23, 24) to an output co-axial with the input. In a second mode, the gearset (18, 19, 20) is locked up to provide direct drive from the variator (10) output to the reduction drive (22, 23, 24). The ratio of the reduction drive corresponds to the maximum step-up ratio of the variator so that in the second mode, with maximum variator step up ratio the overall transmission ratio is 1 : 1 in a third mode the input (14) is coupled (17) directly to the output (16) to bypass the variator and provide direct drive. The epicyclic gearset can be used in a reverse mode to provide a reverse gear.

IPC: H01L29/732
Filed: 1979-09-13
Abstract: The invention relates to the field of bipolar transistors to operate at high voltages, exceeding 100 V. The simultaneous production of these transistors of the various known types, i.e. pnp, lateral and non-lateral pnp and 12L, with a view to combining them by monolithic integration on one and the same substrate, meets with great difficulties on account of the incompatibilities between certain common production stages. According to the invention, in order to surmount them in the pnp and lateral pnp devices, two supplementary regions are created at a high doping level of sign n, one at the emitter junction (32) and the other at the collector junction (25). These devices are employed, in particular, in high voltage integrated circuits incorporating a high degree of integration. <IMAGE>

Abstract: Apparatus for detecting faults in inherent flatness in a moving stretched strip, comprising a deflector roll in the form of a cylinder covered by a thin casing. Cavities are machined in the cylinder and arranged on a helix traced on the roll. Each cavity contains a displacement detector whose moving part in contact with the inner surface of the thin casing moves in the radial direction of the roll under the action of the stresses exerted by the sheet. The detectors have a primary winding and a secondary winding through which passes a core, solid with the moving part of the detector. The apparatus includes an optical encoding system for marking the angular position of the roll and a programming apparatus for sending a pulse of current to the primary windings of the detectors once under load and once not under load. A collector and processor for the emitted signals allow calculation of the values proportional to the tension in the strip, along its width. The invention may be used, for example, for monitoring the inherent flatness of thin, cold-rolled sheets.
