Abstract: A drilling jar (100) includes a swivel (20) which allows the drilling jar to operate substantially independently of any right hand torque that becomes trapped in the drill string. The swivel (20) includes a bearing cage (9) that engages the polished stem (4) of the drilling jar to the jay stem (5) of the drilling jar. This bearing cage (9) holds a number of bearings (10) against the jay stem (5) and the polished stem (4). The swivel (20) allows the jay stem (5) to rotate substantially independently of the polished stem (4). The drilling jar may further include splines (8) formed onto the outer surface of the polished stem (4) for transmitting torque from the polished stem (4) to the barrel (1) of the drilling jar without simultaneously transmitting torque from the polished stem (4) to the jay stem (5). In addition, the drilling jar may include floating pistons (11,12) that are circumferentially engaged to the polished stem (4) and the washpipe (7) that effect the upper and lower seals on the drilling jar and allow the internal pressure inside the tool to be equalized with the internal and external pressures of the drill string.

Abstract: The rotary-piston machine comprises three or more rotary pistons (26) forming a unit (20) inside a gastight chamber (22) in a housing (24). These are similar, and form straight prisms with curved surfaces (28,30) to two different radii, those of the same radius curving through the same angle, and joining alternately together at connecting points (32) tangentially. They are fixed to synchronised shafts (34) rotating in the same direction, while their end faces are in line and they enclose a working chamber (38) between them. The centre distance between their shafts is greater than the sum of the two radii by an amount equal to the gap between adjacent pistons. Each gap contains a sealing strip (42) comprising two parallel sealing bars (44,46) whose dia. is greater than the gap width, and joined by a connecting portion (48) narrower than the latter, its length being equal to that of the pistons.

Abstract: An electrode structure, comprising a number of helical wire filaments, is shaped by forming a cylindrical array of helical filaments, each filament being bonded at one end to a common metallic cylinder and at a second end to a second common metallic cylinder.  The metallic cylinders are mechanically fixed to a common support and mutually insulated.  Additionally the process involves placing around the cylindrical array a form of temperature resistant dielectric material having a cylindrical opening sized to contain the array. The array and form are then placed in an inert environment. The filaments in the inert, environment are heated by passing electric current between the metallic cylinders so that at least some of the filaments expand to be restrained by the surface of the opening.  The electrode structure is cooled such that the filament array contracts away from the form and the form is removed.
