Abstract: A cutting element assembly includes a cutter support including a cutter bore. A cutting element is in the cutter bore and a resilient element is integral with the cutter support. The resilient element is longitudinally compressible and has a displacement of greater than 0.1 mm and optionally less than 2 mm. Another cutting assembly includes a cutter support coupled to multiple cutting elements. A resilient element of the cutter support is compressible based on a force applied to the cutter support through one or more of the cutting elements. The resilient element can include a slit in the cutter support. A slit may, for instance, extend perpendicular or transverse to an axis of the cutting elements and allow the cutter support to flex and close off or reduce a size of the slit when forces act on one or more of the cutting elements.

Abstract: A chemical-agent dosing apparatus for dosing a heating system with chemical agent. The apparatus comprises a chemical-agent storage chamber which stores a chemical agent and a dosing device which has a dosing chamber and a driving means. The dosing chamber is fluidly connected with the storage chamber and defines a dosing volume for receiving a dose of chemical agent. The driving means drives fluid from the dosing chamber via the dose outlet.

Abstract: A boom system for utility service lines (such as cables, wires, hoses, pipes, etc.) for a drilling rig. The mobile boom system includes a skid with posts and one or more booms pivotally attached to each post. One or more articulating booms attached to a first post can support and carry the service lines connected to the sources and one or more articulating booms attached to the second post can support and carry the service lines connected to a drilling rig, or to a boom extending from a drilling rig. The mobile articulating boom system can include means for moving and selectively positioning the mobile articulating boom system at a drilling site. The mobile boom system can be adapted so that it has first, second, and third booms which can be placed in a closed position and fit within a perimeter defined by the skid for easier transportation to and from a drilling site.

Abstract: A system and method for transferring tubular elements may include a first structure having a first horizontal platform attached to the first structure on a bottom side and a monorail attached to the first structure on a top side, a second structure having a second horizontal platform attached to the second structure. The first structure and the second structure may be located proximate to each other, while the monorail can extend from the first structure to the second structure. The monorail can have a motion controlled assembly to move a tubular element or assembly of tubular elements.
