Title: Annulus safety valve
Inventor: HOPPER HANS PAUL
IPC: E21B34/06
Filed: 1990-08-15
Abstract: A fail safe annulus valve for fluids has a valve area across the annulus with inlet and exit ports 35, 36 and a slide valve 33 in the area capable of sliding to open or close the ports 35, 36. The slide valve 33 is biased to its fail safe position by a spring 50, is susceptible to being opened by independent pressure means (e.g. control line 53), and is also susceptible to movement by differential annulus fluid pressure across the valve through ports 57, 58. Thus while it fails safe, it can always be moved by differential annulus pressure. The valve may be used for the annuli of oil or gas wells (eg annuli used for artificial lift) and may be mounted on a packer of the annulus. It may also be used for closing other types of annuli. <IMAGE>

Title: Suction dredgers
Inventor: NAKAHARA TATSUO
IPC: E02F3/92
Filed: 1990-08-17
Abstract: A dredger has a submerged suction pump (26) capable of sucking slurry such as sand and gravel from the bottom of sea, lake, pond or the like, a sedimentation tank (38) disposed at the discharge opening of the suction pump, and a discharge tank (44) for discharging the muddy water separated from the sand slurry in the sedimentation tank. The separated muddy water is discharged to a region near the bottom of the sea, so that the muddy water is not diffused to the surface region of the sea water. This is achieved by a discharge pump (50) connected to the discharge portion (48), and a discharge pipe (52) connected to the discharge opening of the discharge pump (50) and leading to a region near the bottom of the sea, lake, pond or the like. The discharge pipe (52) may be constructed as a unit with the sand transfer line leading from the submerged sand pump or may be fixed thereto such that the discharge opening formed in the end of the discharge pipe is located in the vicinity of the suction opening of the sand pump so that the muddy water may be recycled through the sand gathering system. <IMAGE>

Title: Towing vehicle with liftable front axle.
Inventor: BIRTLEY STANLEY JOHN
IPC: B62D61/12
Filed: 1991-03-06
Abstract: The towing vehicle has a lifting bar (5) which engages the axle (4) of the towed vehicle.
