Abstract: The invention is concerned with a heat transfer tube for use in boiling type heat exchangers, having an excellent heat transfer performance. More specifically, the invention relates to a surface condition of the heat transfer tube for improving the heat transfer performance and a method of producing the tube easily, especially a method for processing the surface condition efficiently and advantageously from an industrial point of view. The essential feature of the invention resides in a provision of a surface condition for promoting the boiling which consists of annular or spiral cavities extending along the tube surface in the circumferential direction of the latter, as well as narrow gaps extending along the cavities so as to allow the cavities to communicate the outside space. If necessary, spiral or annular fins may be provided on the tube surface, so as to improve the boiling performance at the outside of the tube.

Abstract: A double grip well bore packer run into a well casing on a pipe string has actuator means responsive to hydrostatic or applied fluid pressure to set anchor slips and deform a packing into engagement with the casing, and the setting force is locked into the packing. Pressure differential from below the packer actuates hold-down elements into engagement with the casing. A shearable member is sheared by a shear piston which is normally pressure balanced but rendered unbalanced when a releasing tool is seated in the packer and operated so that fluid pressure can act on the shear piston and release the packer for retrieval from the well casing.

Abstract: Diclosed is a connecting assembly for communicating between a first location and a second location lower than the first location, with the two locations separated by a fluid body. A first tube extending between the two locations generally encloses a second tube, and the annular area between adjacent surfaces of the two tubes is sealed toward the second location. The buoyancy of the assembly is selectively controlled by selectively controlling the quantity and density of fluid in the area between the tubes. In an embodiment shown, a marine drilling facility is joined to an underwater well site by a riser with a liner set and sealed therein, and gas-lift pumping is used in controlling buoyancy. In a method, a riser is set between an underwater well site and a marine well operating facility. A first segment of the well may be drilled through the riser. Casing is cemented in the well, and a liner is sealed at its bottom end to the riser.

Abstract: A modular underwater support platform having interconnecting elements is lowered into position by a conductor pipe which in turn is connected to and supported from a drill pipe. Releasable hydraulic connections connect the platform to the conductor pipe and connect the conductor pipe to the drill pipe. After the hydraulic connection between the platform and the conductor pipe is released, the drill pipe drills a hole in the subsea floor for receiving the conductor pipe. The conductor pipe is positioned in the hole, and locked to the platform for supporting the platform. A base may be connected to the bottom of the support platform which includes hydraulic cylinder and piston assemblies for leveling the support platform. Hydraulic control lines are positioned on the support platform and adapted to be in communication with the hydraulic connections when the conductor pipe is locked to the platform for hydraulically releasing the connections allowing the removal of the drill pipe.

Abstract: A process and system is provided permitting the recovery of solid particulate material, particularly solid copolymer beads, from a drilling fluid which also contains drilled solids of the same and larger size as the particulate material. The drilling fluid returns are passed to a separator, such as a shale shaker, which screens from the fluid a major proportion of the drilled solids along with the particulate material. The latter fraction is then passed into a vessel containing a weighted liquid having a specific gravity less than that of the drilled solids but greater than that of the particulate material. In such vessel, the particulate material is allowed to rise to the surface of the liquid while the drilled solids settle therein. The particulate material can then be skimmed from the upper portion of the vessel and returned to the well for recirculation therein.

Abstract: Weighing apparatus and method. A plurality of weigh members are moveable in sequence in a continuous path. Each weigh member receives an item to be weighed and includes a member which is moveable in response to the weight of the carried item. Preferably, the moveable member is elastically deformable. When an item to be weighed is deposited on a weigh member, the moveable member moves in response to the weight and then "springs" back and so on in an oscillating fashion. The weigh members, each carrying an item to be weighed, are rapidly moved in sequence along the continuous path to a weighing location and the time, while short, is sufficient to permit oscillating movement of the moveable member to substantially cease by the time that the weigh member arrives at the weighing location.

Abstract: Apparatus for compacting or consolidating a strip of road surfacing material essentially comprises a self-propelled compacting machine and a guide vehicle. The guide vehicle has a steerable wheel and a set of drive wheels. The compacting machine is guided for orbital movement around the guide vehicle at a preset turning radius. The guide vehicle may be self-propelled in which case it carries its own motor for driving its driving shaft. Preferably the guide vehicle is driven for progressive displacement along the strip of surfacing material in response to the turning of a coupling bar, connecting the compacting machine with the guide vehicle about its end for determining the turning radius of the former. The coupling bar in turn rotatably drives the driving shaft of the guide vehicle which in turn drives the drive wheels of the guide vehicle through a power transmission.

Abstract: An electromagnet for brakes and clutches having outer and inner poles and an electrical coil for creating a magnetic field between these poles is provided having a circumferential gap in the forward portion of the outer pole. The gap reduces the flux density over the forward portion of the magnet face while increasing the flux density over the rearward portion. The variable flux density over the magnet face thus establishes an unbalance of forces attracting the magnet toward the armature plate causing the magnet to engage the armature plate heel first thereby eliminating "squeal" caused by magnet gouging and two plane wear of the magnet's friction face.
