Abstract: A surgical assembly and system are disclosed for use in performing a surgical procedure on a patient. The assembly comprises a surgical tool, the tool being arranged to receive a first signal for use in cutting or cauterizing tissue of the patient during the surgical procedure and an electrode disposed upon the tool. The assembly further comprises an electrical generator communicatively couplable with the electrode, for generating a second signal for use in generating an electrical field from the electrode proximate a site of the surgical procedure, for removing particles suspended proximate the surgical site. The assembly further comprises a controller for controlling the application of the second signal to the electrode, a sensing arrangement for sensing an activation status of the first signal, the sensing arrangement being communicatively coupled with the controller and arranged to output a sensing signal to the controller in dependence of the activation status of the first signal.

The system comprises a first generator for generating a first signal for use in generating an electrical field proximate a site of a surgical procedure for removing particles suspended proximate the surgical site. The assembly further comprises a surgical tool comprising a tool-piece communicatively couplable with the first generator and a second generator, the second generator being arranged to generate a second signal for use in cutting or cauterizing biological tissue of the patient during the surgical procedure, the assembly further comprising a switching assembly for switching the application of the first signal and second signal to the tool-piece and a controller for controlling the application of the first signal and second signal to the tool-piece.

Abstract: Embodiments of the invention are directed to a sulfur trap comprising an inlet, a first chamber, a divider, a second chamber, an outlet, and a float assembly. The float assembly may have many different configurations, but generally comprises a float and plug, is configured to float within liquid sulfur, and is operatively coupled to a seal seat in the divider for sealing and unsealing the first chamber from the second chamber. Generally, only liquid sulfur is allowed to pass from the first chamber into the second chamber. However, the sulfur trap may be configured to allow for pressure relief, such that during an overpressure event the plug and seal seat disengage and allow the liquid-gas mixture to flow into the second chamber to prevent damage within the system. In some embodiments a filter and/or the flow of liquid sulfur is directed to collect debris from the liquid sulfur.

Abstract: A retaining wall has at least two facing panels in a tier adjacently interconnected by at least a pair of panel interconnectors mounted to the inner surfaces of the panels to allow adjacent panels to rotate relative to each other. Horizontal flexible anchoring devices, which include rigid anchors flexibly or rigidly connected to the panel interconnectors, connect the facing panels to an earth mass. The panels may tilt, or horizontally deform, relative to deformations in the earth mass. Front horizontal panel adjustment devices allow the tension of the connection between the flexible anchoring devices and the panel interconnectors to be varied from the front of the wall to allow horizontal alignment of the panels after the earth wall has been built. An adjustable inner panel supports the facing panels prior to the start of earth wall construction. Geofabric layers, independent of the flexible anchoring, are used during construction to stabilize the earth wall.

Abstract: A boulder rolling down a slope is caught with an energy absorbing device to dissipate a portion of its kinetic energy and to redirect the boulder downwardly into the ground to absorb the rest of the kinetic energy and to stop it. This is accomplished by temporary deformation of joints in the energy absorbing device to dissipate the kinetic energy and redirect the boulder downwardly into the ground. The energy absorbing device will return substantially to its undeformed state for intercepting additional boulders which may roll down the slope.
