Abstract: An equipped balancing jacket includes a back and a first stage reducer connected to the compressed air bottle/bottles. From the first stage reducer project high pressure and low pressure hoses. The high pressure hose is directly connected to a computer and/or a manometer, while the low pressure hose is connected to a dispenser from which project the hoses for different functions. Alternatively, the low pressure hoses is connected to the dispenser through the intermediary of an intermediate dispenser, from which projects also the hose for the connection to the control device.

Abstract: The present invention relates to a bearing device including a body formed with an inner groove that does not communicate with the shaft hole of the body. Thus, when the rotation shaft is rotated, the lubricating oil may lubricate the rotation shaft, and may flow back to be stored in the inner groove after the rotation shaft stops rotating, thereby achieving the effect of recycling use. At the same time, the inner groove does not communicate with the inner shaft hole, such that when the rotation shaft is rotated, the lubricating oil contained in the inner groove will not be directly carried out of the body and will not sputter out of the body. Thus, the amount of loss of the lubricating oil may be reduced, thereby increasing the lifetime of the bearing device.

Abstract: A cap (1) is provided for fitting to the end of a hollow post. A number of hollow posts are used in viticulture to support wires on which grape vines are trained to grow. Caps (1) are fitted to the ends of the posts to inhibit snagging of netting which is placed over the posts to attempt to protect a crop of grapes from being eaten by birds. The cap (1) has a generally domed head (3) and a stem (5). The stem (5) has at least one radially outwardly extending abutment (13, 15) which, in use, engages with an inner wall of a hollow post. The abutment (13, 15) provides an interference fit of the stem (5) in the post such that to insert the stem (5) substantially all the way into the post requires force fitting and either deformation or shearing of material from the abutment (13, 15).

Said device comprises a basket of an essentially cage-like structure open at the front and provided at the bottom and top with supporting surfaces, the said cage-like structure pivoting in the center of its flanks on the flanks of the chamber of the said machine.

Abstract: A tensioning device for the fastening belt of compressed gas bottles to the back of a jacket or the like for underwater activities. A pneumatic jack is inserted between the two ends of the bottle fastening belt and connected to a suitable compressed gas source through at least one hose provided with a joint for connection with the jack. The jack is fit to supply an optimal tensioning strength of the belt for its tightening on the bottles. The pneumatic jack is connected to the joint through a coupling device which is manually controllable by the diver to allow the supplying of compressed air to the jack through the opening of a suitable valve positioned in the joint.

Abstract: The present invention is an improved method of installing a flowline below the surface. The method includes the steps of establishing first and second sight relief holes along a linear path, positioning a directional drilling machine on the surface, boring a first portion of a pilot hole from the surface to the first sight relief hole, determining the elevation of the boring tool and adjusting the boring tool to the desired depth, boring a second portion of the pilot hole to the second relief hole, and determining the elevation of the boring tool and adjusting the tool to the desired depth. In another aspect of the invention, a method for directionally boring a flowline is provided.

Abstract: A hydrodynamic separator to separate floatable material from a liquid includes a separating vessel having a cylindrical outer wall; an inlet means for introducing the liquid into the vessel in a manner to promote a low energy rotational flow of liquid in the vessel; a base at one end; a top wall at the end opposite the base, the top wall including an axial outlet opening for receiving a flow containing floatable material separated from the liquid flow to the vessel; a flow modifying member provided within the vessel to define with the top wall an annular opening which is spaced from the outer wall; an annular dip plate spaced from the outer wall of the vessel, the dip plate comprising an upper edge spaced from the top wall to define a gap for the flow of liquid containing floatable matter; and an outlet separate from the axial outlet opening in the top wall, comprising a conduit for removing a primary liquid flow from the vessel, which conduit communicates with the interior of the vessel at a substantially ax

Abstract: An apparatus for delivering substantially spherical products into a substantially rectangular container having an open top. The apparatus is provided with a delivery element arranged to be movable up and down relative to the container. The container is movable in a horizontal direction relative to the delivery element. The delivery element includes at least one endless conveyor which is provided with supporting elements which define a number of supporting surfaces extending in horizontal direction. An intermediate conveyor is arranged upstream of the delivery element. The intermediate conveyor is aligned with the delivery element and is arranged for row-by-row transfer of the products to the delivery element. A vibrating feeder is arranged upstream of the intermediate conveyor. The vibrating feeder has a discharge side aligned with an infeed side of the intermediate conveyor.

Abstract: A valve for underwater aqualung supplying devices, including a pressure chamber and a watertight compensation chamber adjacent and watertightly separated by a partition wall. A shutter including a tubular stem inserted, at least in part, inside each chamber. The pressure chamber connected to a pressurized gas source and a housing suitable for cooperating with an end connected with the shutter. The compensation chamber is provided with at least one opening communicating with the outside and a stem end in the shape of an expansion enlarged head connected with the valve outlet. A coil spring is watertightly driven into the chamber between the expansion head and the partition wall. In the valve the enlarged expansion head of the shutter is encircled by a thermal insulating annular part watertightly positioned between the head and the side wall of the compensation chamber.

Abstract: A flashlight comprises a barrel, a lamp shield assembly, and a lamp seat assembly. The lamp seat assembly includes a lamp seat, a movable seat, and a lamp mounted on the movable seat. The position of the movable seat in the lamp seat can be adjusted to locate the filament of the lamp in the focus of the reflective member of the lamp shield assembly so that the light beams emitted from the lamp can travel a long distance.

Abstract: A method and apparatus for making a pipe liner and the pipe liner itself. A thin walled pipe liner, after being provided cooled from a spool or extruded in tubular form and cooled, is deformed to a smaller cross section at ambient temperature. The pipe liner is then encased and held in its reduced cross section deformed shape by a protective sleeve which is co-extruded directly over the pipe liner. The sleeved pipe liner may then be wound on a drum for transport to a remote location. Ducts for water may pass through the pipe liner. Other ducts, for example, for fiber optics, may pass through the sleeve either within or outside of the deformed pipe liner.

Abstract: A running fluid seal arrangement (10) includes a passage for receiving cable (12) with chambers (20,21 and 22).
