An electrosurgical flux supply unit includes a first terminal configured to deliver a first electrical flux, the first terminal being configured to be electrically coupled with a first electrode of a first electrosurgical instrument, a second terminal configured to receive a second electrical flux; the second terminal being configured to be electrically coupled with a second electrode of the first electrosurgical instrument, and an electrical switching mechanism selectively configurable between a first state and a second state. In the first state, the electrical switching mechanism electrically couples the first electrode with the first terminal and, in the second state, the electrical switching mechanism electrically isolates the first electrode from the first terminal. The electrosurgical flux supply unit is configured to maintain the electrical coupling of the second terminal with the second electrode in both the first state and the second state of the electrical switching mechanism.

An electrosurgical instrument may comprise a pair of jaw members configured to move between an open position and a closed position. In the closed position, the pair of jaw members may be configured to exert a gripping force on material placed between working surfaces of the pair of jaw members. A first jaw member of the pair of jaw members may comprise a first electrode, and a second jaw member of the pair of jaw members may comprise a second electrode and a third electrode.

An electrosurgical end effector for a surgical tool to perform teleoperated surgical operations. The electrosurgical end effector comprises a first end effector jaw; a second end effector jaw coupled to the first end effector jaw; and a coupling pin configured to rotatingly couple the first end effector jaw to the second end effector jaw so as to cooperatively rotate open and close about an axis of rotation. The electrosurgical end effector further comprises an actuation mechanism coupled to an end of the first end effector jaw to rotate the first end effector jaw about the coupling pin; an otomy feature coupled to the second end effector jaw; and a first electrical conductor to electrically couple the otomy feature to a generator. In one embodiment, the otomy feature is electrically activated by contact with a cam portion of the first end effector jaw, when opened beyond a predetermined jaw angle.

A fence post and support base are made of cast concrete. The base has a substantially planar bottom and an upper surface that is essentially parallel with the bottom of the base. The post extends substantially perpendicular from the upper surface of the base. The planar bottom surface of the base has a substantially larger area than the area encompassed by the interface between the post and the upper surface of the base so that the base provides a sturdy, support for the post. The base and the post are preferably cast as separate members, and a connecting mechanism is provided for interconnecting the post with the base.

A cast concrete block that is cast on its side and can be separated into at least three construction blocks to be used in constructing a retaining wall system. The cast concrete block has a top face and a bottom face. The block is bounded by an elongate base side, two elongate edge sides and an elongate top side. First and second elongate splitting grooves are formed in at least one of the top face and bottom face. The splitting grooves extend between the top side and the base side. The splitting grooves are spaced inwardly from the opposite first and second edge sides. Preferably, each of the splitting grooves are paired with a corresponding secondary groove in an opposite face of the block so that each splitting groove and its corresponding secondary groove are parallel with each other and lie in a common plane that is substantially perpendicular to the broad faces of the block.

An elongate shoring device capable of supporting a high longitudinal loading with the ability to yield uniformly in a direction along the longitudinal dimension of the shoring device when the longitudinal loading on the shoring device exceeds a preset magnitude. The shoring device comprises an inner elongate tube which is received within an open end of an outer elongate tube for longitudinal, telescopic movement within the outer tube. A storage compartment having a variable volume is formed by the inner and outer tube when the inner tube is received through the open end of the outer tube, with the volume of the storage compartment decreasing as the inner tube moves in its longitudinal, telescopic movement into the outer tube. A solid, non-compressible material is contained in the storage compartment, and a relief opening is provided in communication with the storage compartment. The solid material allows the inner and outer tubes to sustain longitudinal loading up to a preset magnitude, and when the longitudinal loading exceeds the preset magnitude, the shoring device yields uniformly along its longitudinal dimension as a result of a portion of the solid material being ejected from the storage compartment through the relief opening thereby allowing the inner tube to move further into the outer tube.

Elongated shoring device

An alignment and lateral support member for use in laying common concrete blocks. The support member comprises an elongate body piece of rigid material having a length which is greater than the width of concrete blocks with which the support member is to be used. A first appendage extends from a first face of the body piece. The first appendage has a stop surface extending substantially perpendicular to the first face of the body piece, with the stop surface of the first appendage being positioned a distance from the first end of the body piece so that when the stop surface of the first appendage engages an outer surface of the sidewall of a first concrete block, with the first face of the body piece lying adjacent to the first block, the body piece spans from one sidewall of the first block to the other sidewall of the first block. A second appendage extends from a second face of the body piece. The second appendage has a stop surface extending substantially perpendicular to the second face of the body piece, with the stop surface of the second appendage being spaced from the stop surface of the first appendage by a set distance along the body piece in a direction toward the first end of the body piece, whereby the stop surface of the second appendage engages an inner surface of the sidewall of a second concrete block when the second block lies above the first block and in proper position adjacent to the second face of the body piece.
