Abstract: A dental polishing paste and a method of surface finishing a dental ceramic with the dental polishing paste is described. The dental polishing paste includes 60 to 90 weight percentage (wt. %) glycerin; 7.5 to 17.5 wt. % inorganic nanoparticles such as, diamond or zirconia, having a mean particle size of 5 to 25 nanometer (nm); and 2.5 to 32.5 wt. % additive, each based on a total weight of dental polishing paste.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a casing, a heat exchanger disposed in the casing and comprising a V-shaped arrangement having (e.g., formed by) a first leg and a second leg, a delta plate extending from the first leg to the second leg, and a refrigerant sensor configured to detect a refrigerant leak associated with the HVAC unit, wherein the refrigerant sensor is coupled to the delta plate.

Abstract: A suction tube for a heat exchanger system includes a first tube segment and a second tube segment. The first tube segment includes a first end and a second end, wherein the first end is configured to fluidly couple to a heat exchanger of the heat exchanger system, and wherein the second end comprises a first alignment feature. The second tube segment includes an additional first end and an additional second end, wherein the additional first end is configured to couple to the second end of the first tube segment, the additional second end is configured to extend through a tubing access panel, and the additional first end comprises a second alignment feature configured to align with the first alignment feature during assembly of the heat exchanger system to align the additional second end of the second tube segment with an opening of the tubing access panel.

Abstract: Examples relate to setting a performance mode of an RF receiver front end. An example method includes determining a power state of an input signal to an RF receiver front end; and setting a performance mode of the RF receiver front end to one of at least three distinct performance modes offered by the RF receiver front end at least partially responsive to the determined power state of the input signal.

Abstract: A reversible reciprocating mechanism has a single crankshaft and geometrical equilateral shapes to organize positive displacement reciprocating movement with liquid movement for pumping or energy recovery systems.

Abstract: A method for producing a dense and tenacious coating with a thermal spray gun including a nozzle member and a gas cap. The gas cap extends from the nozzle and has an inwardly facing cylindrical wall defining a combustion chamber with an open end and an opposite end bounded by the nozzle. An annular flow of a combustible mixture is injected at a pressure of at least two bar above atmospheric pressure from the nozzle coaxially into the combustion chamber. An annular outer flow of pressurized air is injected from the nozzle adjacent to the cylindrical wall. Powder particles having a heat-stable, non-fusible component and a heat-softenable component, and entrained in a carrier gas, are fed axially from the nozzle into the combustion chamber. An annular inner flow of pressurized air is injected from the nozzle into the combustion chamber coaxially between the combustible mixture and the powder-carrier gas.
