Methods are disclosed for performing operations such as cleaning, inspection or data acquisition on an external surface of a hollow cylindrical tubular. Preferred embodiments include providing a fluid dispenser and an abrasion assembly on a buggy that travels up and down the length of the tubular as the tubular rotates. The fluid dispenser includes nozzles that dispense cleaning fluids onto the tubular's external surface. The abrasion assembly includes a swivel brush and a brush train providing different styles of abrasion cleaning of the tubular's external surface. Preferred embodiments include robotically monitoring abrader contact against the external surface of the tubular, and, in response, dynamically adjusting the distance between the external surface of the tubular and the abrasion assembly.

A grinding apparatus includes a table that holds a workpiece, and a grinding unit including a grinding wheel mounted to a spindle. The grinding wheel has a grindstone formed by binding abrasive grains with a bonding agent. In addition, the grinding apparatus further includes: a grinding water supply unit that supplies grinding water to at least the grindstone; a light applying unit that is disposed adjacent to the table and that applies light to a grinding surface of the grindstone grinding the workpiece held by the table; and a light applying unit moving section by which the light applying unit can be positioned at a first position on a rotational trajectory of the grinding wheel in the case where the grinding wheel has a first diameter and a second position on a rotational trajectory of the grinding wheel in the case where the grinding wheel has a second diameter.

A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.

The invention relates to a tail stock device (10) for supporting a workpiece in a machine tool, for example a grinding machine. The tail stock device (10) comprises a tail stock arm (16) that is pivotally supported about a pivot axis (S), said tail stock arm having arranged on its outer end (16a) a centering tip (12) that is oriented parallel to the pivot axis (S). By means of a pivot drive (30) comprising a first pneumatic cylinder (31), the tail stock arm 16 can be pivoted between a working position (A) and a resting position (R). The movement of the piston (32) of the first pneumatic cylinder (31) is transmittedvia a first coupling arrangement (35)to the tail stock arm (16). When the tail stock arm (16) is in working position (A), the first coupling arrangement (35) assumes a self-locking position in which a force feedback effect being triggered by a torque that forces the tail stock arm (16) out of working position (A) and into resting position (R) does not or only minimally retroact on the piston (32) of the first pneumatic cylinder (31).

A motorized blade rest apparatus for a grinding system includes a carriage, a ram assembly, a work rest assembly, a motor, and a computer processor. The carriage moves a regulating wheel along a first axis towards and away from a work wheel. The ram assembly, which moves along a second axis parallel to the first axis, supports the carriage and the work rest assembly. The work rest assembly includes first and second slide portions and a work rest blade. The first slide portion is mounted on the ram assembly. The second slide portion, which is movable relative to the first slide portion, moves along a third axis perpendicular to the first axis. The work rest blade is mounted on the second slide portion. The motor is coupled to the second slide portion, and the computer processor controls the motor to move the second slide portion along the third axis.
