Title: Vibration damping device, in particular torsional vibration damper and process for controlling hysteresis
Inventor: BASTEL NORBERT
IPC: F16F15/139
Filed: 2001-07-17
Abstract: The invention concerns a vibration damping device (2). This includes at least two elements - a primary element (3.1) and a secondary element (3.2) -, which are limited in movement in relation to each other. The primary element (3.1) and the secondary element (3.2) can be coupled together using a spring coupling. The means to implement spring coupling include at least one spring device (4.1, 4.N). Based on the invention, there is at least one adjustable clutch device (15, 15'), including at least two elements (16, 17; 16', 17') rubbing against each other, which bring primary and secondary elements (3.1,3.2) into friction contact. In addition, there is a power generator or force producing device (39) to produce a controllable friction contact for the elements rubbing against each other (16, 17;  16', 17').

Inventor: SIMPSON NEIL ANDREW ABERCROMBI
IPC: E21B7/00
Filed: 1999-12-21
Abstract: Methods and apparatus for shaping pipes, tubes, liners, or casing at downhole locations in wells. Use is made of rollers bearing radially outwards against the inside wall of the pipe (etc.), the rollers being rolled around the pipe to cause outward plastic deformation which expands and shapes the pipe to a desired profile. Where one pipe is inside another, the two pipes can be joined without separate components (except optional seals). Landing nipples and liner hangers can be formed in situ. Valves can be deployed to a selected downhole location and there sealed to the casing or liner without separate packers.  Casing can be deployed downhole in reduced-diameter lengths and then expanded to cast a well without requiring larger diameter bores and casing further uphole. The invention enables simplified downhole working, and enables a well to be drilled and produced with the minimum downhole bore throughout its depth, obviating the need for large bores. When expanding lengths of casing, the casing does not need to be anchored or made pressure-tight. The profiling/expansion tools of the invention can be deployed downhole on coiled tubing, and operated without high tensile loads on the coiled tubing.

Inventor: MICHELI JOHN
IPC: H02K21/24
Filed: 2000-01-11
Abstract: A magnetic induction drive for a rotatable driven member in a sealed housing, in particular, a shaft-mounted blade in a blender cup or a shaft-mounted blade in an ice shaver, uses a comparatively thin circular drive plate of a magnetizable material with circumferentially arrayed poles enclosed within a housing secured to a drive shaft. A brushless d.c. motor in a base separate from the housing has a rotor formed as an array of pie-shaped permanent magnet regions that interact with an electronically controlled, rotating electromagnetic field produced by a ring of stator coils. A second such permanent magnet is coupled to rotate coaxially and in unison with the rotor, with poles of opposite polarity aligned and adjacent one another. A steel disc is sandwiched between and bonded to the rotor and the second permanent magnet. The magnetic field (lines of flux) of the second magnet extends axially away from the rotor to induce magnetic poles of opposite polarity in the drive plate. This second magnet-to-plate magnetic coupling operates across a closely-spaced gap that includes the bottom wall of the base, the upper wall of the housing, and air gaps between these walls, and the plate and the second magnet. A gear train assembly can be coupled to the drive shaft to increase or decrease the amount of torque transmitted from the drive plate to the driven member.
