Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: The instant disclosure is generally directed to low viscosity, low volatility lubricating compositions. The lubricating composition of the instant disclosure includes an oil of lubricating viscosity that contains a lubricating base oil and a hydrocarbon oil. The hydrocarbon oil makes up least 20 wt % of the oil of lubricating viscosity and has a kinematic viscosity of less than 3.7 c St at 100° C. and a NOACK volatility (measured by ASTM D5800) of less than 25 wt %. The lubricant composition further includes a polyalkenyl succinimide dispersant, and, optionally, other formulation additives. The lubricating compositions have been shown to increase fuel economy in internal combustion engines.

Abstract: A micro-valve includes an orifice plate having a first surface, a second surface and an orifice extending from the first surface to the second surface. An actuating beam is disposed in spaced relation to the orifice plate. The actuating beam includes a base portion and a cantilevered portion. The base portion is separated from the orifice plate by a predetermined distance. The cantilevered portion extends from the base portion such that an overlapping portion thereof overlaps the orifice. The actuating beam is movable between a closed position and an open position. The micro-valve also includes a sealing structure including a sealing member disposed at the overlapping portion of the cantilevered portion. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve.

Abstract: A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion.

The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.

Abstract: A corona comprises a central electrode surrounded by an insulator, which is surrounded by a conductive component. The conductive component includes a shell and an intermediate part both formed of an electrically conductive material. The intermediate part is a layer of metal which brazes the insulator to the shell. An outer surface of the insulator presents a lower ledge, and the layer of metal can be applied to the insulator above the lower ledge prior to or after inserting the insulator into the shell. The conductive inner diameter is less than an insulator outer diameter directly below the lower ledge such the insulator thickness increases toward the electrode firing end. The insulator outer diameter is also typically less than the shell inner diameter so that the corona igniter can be forward-assembled.
