Title: Underwater oil production
Inventor: TOFT RICHARD CHARLES
IPC: F16L1/14
Filed: 1988-06-16
Abstract: A method for producing oil from an underwater seabed well-head 3 via a flexible riser 4 to a dynamically-positioned vessel 5, without the use of a swivel coupling connecting the riser to the vessel or a coupling requiring pipe to be wound and unwound, comprises the use of a flexible riser 4. The length of the flexible riser 4 and the position of the vessel 5 in relation to the well head 3 is such that the riser has a portion A-B adjacent to the well-head 3 which bends under its own weight, a portion B-C extending more or less horizontally capable of lateral movement, and a portion C-D adjacent to the vessel, capable of vertical and lateral movement. The riser length is significantly greater than the depth of water in which the well is located to allow for the horizontal portion of the riser and the riser construction is such that it has significantly greater stiffness in torsion than in bending. The vessel is kept on station in such manner that it is not stationed directly above the well and such that the locus of the nominal centre of the dynamically positioned footprint of the vessel can describe a curved path which is also offset from the sea-bed well position. <IMAGE>

Title: Automatic transmission having clutch actuator with cancel chamber comprising centrifugal compensation
Inventor: MICHIOKA HIROFUMI
IPC: F16D67/04
Filed: 1993-01-29
Abstract: The automatic transmission is provided with at least one friction element 32 and a piston 33. Engagement of the friction element 32 occurs when operating pressure is applied to an apply chamber 35 to cause the appropriate piston stroke. Disengagement of the friction element 32 occurs when operating pressure is applied to a cancel chamber 35a to cause the appropriate piston stroke. The outer diameter (r) of the pressure-receiving surface in the cancel chamber 35a is substantially the same as that (R) in the apply chamber 35. Therefore, piston pushing force due to centrifugal force in the apply chamber 35 is balanced with piston reverse pushing force due to centrifugal force in the cancel chamber 35a. This prevents the friction element 32 from being dragged while in the disengaged condition. <IMAGE>

Filed: 1993-02-04
Abstract: An iris for a camera or controlling fluid flow comprising a rotor, a stator and a plurality of blades 200 has reduced sensitivity of the aperture area to small rotor movements at the low-aperture settings by arranging for the blades to form the aperture by means of a specially shaped end portion opposite the pivot point, such that the edge 220 where it forms part of the aperture extends in the same direction as the blade movement. The shape of the end portion is dictated by the relationship required between the angle of blade rotation and the area of aperture to be formed thereby. In particular, the invention enables the aperture area to be doubled for each constant increment of blade rotation. <IMAGE>
