    摘要: L'invention concerne un robot pour tennis de table envoyant une balle à un joueur afin de simuler une situation de jeu réaliste, le dispositif comprenant une unité de tir, une unité de réception et une unité de récupération. Une plaque d'amortissement (1) est située sur la table de ping-pong, sur le côté de la table opposé au joueur. Ladite plaque d'amortissement (1) ralentit et dirige les balles venant du joueur. Un mécanisme de déclenchement assure que le joueur reçoit une balle de retour lorsque celui-ci frappe une balle correctement. Ledit dispositif peut comprendre plus d'une unité de tir auxquelles sont associés des mécanismes de déclenchement, de sorte que les balles de retour proviennent de la même zone que celle vers laquelle le joueur a envoyé la balle.

    摘要: The invention provides an improved shotgun barrel (10) which includes a plurality of lands (14), for example, six, which reduce spin or rotation of the wad and hence reduce the dispersion or spread of the associated shotgun pellets. The lands are formed by depositing a material, for example, chrome, onto the barrel's internal surface (12). The lands (14) extend for the full length of the barrel and are preferably equidistantly spaced around the barrel and parallel to the barrel's central axis.

    摘要: A top head drive assembly (20) includes a tubular quill (40) having a central passageway (42) aligned with an axis (44). The quill (40) is supported for rotation on a load beam (22) included in the top head drive assembly (20) such that the quill (40) is movable along the axis (44) through a range of travel sufficient to provide thread protection to the down hole tubulars (34) during tubular handling operations. Splines (50, 104) drivingly connect the quill (40) with a transmission (30) such that the transmission (30) is operative to rotate the quill (40) throughout the range of travel of the quill (40) along the axis (44). A blowout preventer valve (110) is mounted in an upper part of the quill (40) to move axially and rotationally with the quill (40) in order to eliminate sliding or rotary seals between the blowout preventer valve (110) and the drill string (34).

    摘要: Guard system for protecting some space against undetected intrusion uses a plurality of wave beam paths (from transmitter T1-Tn to receivers R1-Rn) selectively energised in cycles (multiplexer Tx-Mx) so that each beam (transmitters T1-Tn) is energised for part only of each cycle. Pressure or absence of beam energy indicative of intrusion is monitored (receivers R1-Rn and multiplexer Rx-Mx). Signal level discrimination (46) of received signals operates both logic circuitry (flipflop 55) to give effectively continuous output (56, 58) except for beam interruption (52) even through a quiescent state of each cycle, and fault indication logic circuitry (100 via 70, 72) that is shown duplicated.

    摘要: An internal wrench (40) for earth drilling machine (10) of the type having a mast (12), a top head drive assembly (14) mounted for movement a!ong the mast (12) and a quill (24) rotated by the top head drive assembly (14) includes a body (42) having an upper end (44) and a lower end (46) sized to fit within a length of casing (26). The upper end (44) of the body (42) is mounted to the quill (24) for rotation with the quill (24) and several jaws (60) are mounted to the lower end (46) of the body (42) to move between an extended position in which the jaws (60) engage in interior surface (30) of the casing (26) to rotate the casing (30) with the body (42), and a retracted position in which the jaws (60) are out of engagement with the interior surface (30). The jaws (60) are selectively moved between the extended and rectracted positions in response to rotation of the body (42) by a system (66-86) which includes s drag ring (93) which operates the jaws (60) and a friction brake, (96) which engages the drag ring (93). A plug (54) is mounted to an intermediate portion of the body (42) to mate with threads at the upper end of the casing (26) to seal off the casing. Followers (100) on selected jaws (60) automatically retract the jaws (60) when the body (42) is lowered into the casing (26) to mate the plug (54) with the threads at the upper end of the casing (26).

    摘要: A top head drive assembly (14) for a drilling machine (10) includes a wrench assembly used to make up and break out threaded connections. This wrench assembly (50) is mounted for axial movement on rails (66) of the top head drive assembly, and is positioned immediately under the quill (30). The top head drive assembly (14) also includes a tubular support assembly (90) which includes slip type inserts (120) for supporting a string of down hole tubulars (32, 34). This support assembly (90) can be pivoted (via 132) out of alignment with the drilling axis or can be locked (via 134) in alignment with the drilling axis. A plurality of centering elements (152) are mounted under the support assembly (90) and are movable to center the upper end of the tubular for insertion into the tubular support assembly (90). Preferably, both the top head drive assembly load beam (16) and the support beam (92) of the support assembly (90) are formed of box sections having converging side plates (not referenced; 100) and internal diagonal brace plates (182; 106) which transmit downard forces on the beam into forces tending to cause the side plates to diverge. Divergence of the side plates is prevented by support plates (not referenced; 110) which surround the beam.
