Abstract: A sensor plug for use in sensing a plurality of operating conditions of a gearbox is disclosed. The sensor plug includes a body defining an axis. A probe end is formed at one end of the body and is particularly adapted for attaching to an oil drain plug of the gearbox. A plurality of sensors are located within the body for sensing operating conditions of the gearbox through the probe end. Examples of the sensors located within the body include a vibration sensor, a temperature sensor, and a pressure sensor.

Abstract: Process and furnace for the continuous production of a molten pool from particulate meltable batch materials such as glass-forming raw materials. The raw materials, in particulate form, are injected into and suspended in combustion gases within a combustor section to form a particle-laden gas flow. The gas flow is accelerated vertically downwardly into a refractory chamber to impact the surface of a molten pool, producing inertial separation of the molten particles into the pool and strong shear forces by the exiting combustion gases, resulting in pool circulation and improved fining and homogeneity.
