  • Patent number: 10384338
    Abstract: A robotic vehicle is provided with an extendable arm and a mandible structure. The mandible structure includes a pair of mandibles with toothed portions that cooperatively engage such that the mandibles may be opened and closed by applying a force to only one of the pair of mandibles. The mandible structure hangs freely from the extendable arm and is balanced so that the mandible structure naturally maintains a substantially vertical orientation. In the closed position, the mandible structure defines an interior cavity suitable for securely grasping a ring.

  • Patent number: 10389258
    Abstract: The invention relates to an integrated magnetic component (802) for a power converter including N>=2 LLC converters configured for interleaved operation. The integrated magnetic component (802) includes a first yoke and a second yoke and for each LLC converter a winding carrying leg which comprises a primary winding (820c) and a secondary winding (821c), wherein the primary winding (820c) and the secondary winding (821c) are wound on the respective winding carrying leg. The integrated magnetic component (802) further includes one or more return legs. Herein the winding carrying legs and the one or more return legs are arranged side by side, each leg being magnetically connected to both yokes and the winding carrying legs include a transformer air gap (819) whereas the at least one return leg is air gap free and at least one return leg is arranged between two winding carrying legs.

  • Publication number: 20170107939
    Abstract: The object of the invention is to provide a cylinder head cover which comprises an integrated valve device and is easy to produce. To achieve this object, according to the invention the cylinder head cover comprises the following: a cover body which, when the cylinder head cover is mounted, is arranged on an engine block of the internal combustion engine and covers a cylinder head of the internal combustion engine; a valve device comprising a valve body and a main body for receiving the valve body, the main body of the valve device being secured to an inner face of the cover body by means of a weld joint.

  • Publication number: 20080066581
    Abstract: A shank configuration for rotary drill bits, is disclosed for positioning of the shank in relation to the bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90°. Further, a stress state may be developed within the multi-pass weld. A method of manufacture is also disclosed.

  • Publication number: 20060278436
    Abstract: A rotary drilling apparatus and method for drilling subterranean formations, including a body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation, so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per rotation of the drilling apparatus, as well as to control the amount of torque experienced by the drilling apparatus and an optionally associated bottomhole assembly regardless of the effective weight-on-bit are all disclosed. The exterior of the drilling apparatus may include a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the drilling apparatus against the bottom of the borehole without exceeding the compressive strength of the formation rock.

  • Publication number: 20050284660
    Abstract: A rotary drag bit and method for drilling subterranean formations, including a bit body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation, so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per bit rotation, as well as to control the amount of torque experienced by the bit and an optionally associated bottomhole assembly regardless of the effective weight-on-bit are all disclosed. The exterior of the bit preferably includes a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the bit against the bottom of the borehole without exceeding the compressive strength of the formation rock.
