Abstract: A remotely operated abrasive blasting apparatus is provided. Systems incorporating the apparatus, and methods of treating surfaces using the apparatus and systems are also provided. The abrasive blasting apparatus eliminates the need for human operators to be present in the area being treated, and allows areas inaccessible to human operators to be treated.

Abstract: A motorized apparatus for use in maintaining a pipe includes at least one drive portion including a body assembly, a plurality of leg assemblies coupled circumferentially around the body assembly, a plurality of drive mechanisms coupled to the plurality of leg assemblies, and a drive portion coupling mechanism. The motorized apparatus also includes at least one maintenance portion including a body, at least one maintenance device coupled to the body, and a maintenance portion coupling mechanism configured to engage the drive portion coupling mechanism. The at least one drive portion is releasably coupled to the at least one maintenance portion by engaging the drive portion coupling mechanism with the maintenance portion coupling mechanism. The drive portion coupling mechanism and the maintenance portion coupling mechanism are each configured to engage another coupling mechanism when the drive portion coupling mechanism and the maintenance portion coupling mechanism are uncoupled from each other.

Abstract: A method for cleaning a coke deposit from an internal surface of a process equipment, comprising removing at least a portion of the coke deposit from the internal surface using a flexible pig comprising a plurality of bristles, without damaging a metal protective layer of the internal surface of the process equipment. A flexible pig for cleaning a coke deposit from an internal surface of a process equipment without damaging a metal protective layer of the internal surface, comprising a flexible body formed of a polymeric material, and a plurality of bristles partially encapsulated by the polymeric material of the flexible body.

Abstract: Embodiments of the disclosure include an endoscope tip assembly for use on an endoscope, during procedures. The endoscope tip assembly may include a base configured to receive an endoscope tip configured to not disengage from the endoscope tip during a procedure. The endoscope tip assembly may also include a plurality of struts which is connected by a webbing, may fold flat during insertion, and may assume a balloon-like shape during withdrawal.

Abstract: A device for traversing a conduit includes a body having a first member that is receivable within a second member. The first member is slidable relative to the second member. A first actuator is coupled to a first end of the body. A second actuator is coupled to a second end of the body. A third actuator is coupled to the body between the first actuator and the second actuator. The third actuator is also spaced apart from the first actuator and the second actuator. The device also includes a pneumatic system that is configured to change the pressure of the actuators.

Abstract: A wire adjuster for adjusting a position of an element within a limb of a breathing circuit. The wire adjuster comprises an interior wall engaging portion configured for engaging a surrounding interior wall of said limb and an element receiving portion coupled with the interior wall engaging portion, wherein the element receiving portion is configured for releasably securing the element as the wire adjuster is movably engaging with the surrounding interior wall, such that the wire adjuster can be used to selectively locate an element within the limb of the breathing circuit.

Abstract: The invention relates to a device for introducing a draw wire or element (4) into tubes, comprising (a) a first actuation body (5) into which the draw wire or element (4) is slidingly guided, (b) a first clamping device (1, 01) that is arranged in the first actuating body (5) and that blocks and releases the movement of the draw wire or element (4), (c) a second actuating body (6, 7) into which the draw wire or element (4) is slidingly guided, (d) a second clamping device (2, 02) that is arranged, preferably, in the second actuating body (6, 7) and that blocks and releases the movement of the draw wire or element (4), (e) a telescopic tube (8, 08) that joins the first clamping device (1, 01) and the second clamping device (2, 02). The fact that the telescopic tube (8, 08) is rotationally fixed permits a problem-free introduction, even in difficult situations.
