    摘要： A microwave vacuum oven for quickly removing volatile material from laboratory samples: The oven has a vacuum chamber for receiving the samples in a closed vessel and a vacuum source for expelling volatile material. This vessel has preferably a deformable gasket for sealing engagement with a top and bottom portion, and a gas passage is also provided therein for easily removing the top portion. Auxiliary components are also disclosed for gradually decreasing the microwave energy output in accordance with residual volatile material present at a given time in a system. A method described includes (a) maintaining a vacuum environment around a sample containing volatile material, (b) subjecting the sample to microwave radiation energy, to rapidly liberate its volatile material while measuring the rate of volatilization of the sample over time, (c) detecting the point at which said rate of volatilization decreases, (d) at said point decreasing the amount of radiation energy generated into said sample, while maintaining vacuum and continuing detecting the rate of volatilization, until said rate stops, indicative that said volatile material is completely liberated from said sample, and (e) stopping the radiation at or near the point at which said volatile material is completely liberated from said sample while said vacuum is maintained until the environment surrounding said sample is substantially free from any volatile material liberated from said sample.

    摘要： A control means for use in a mining apparatus includes a radiation-emitting device on a cutting machine, a number of receiving devices, one associated with each roof support of the apparatus, for receiving radiation from the radiation-emitting device as the machine passes a receiving device, whereby a main control signal is generated, and advance-initiating means for each roof support, responsive to a command signal. A main conductor is connected to the receiving devices for carrying a main control signal, and disabling means is associated with each advance-initiating means and main conductor for rendering a said advance-initiating means non-responsive to a command signal applied to that means when the main control signal is above a pre-determined value. Attenuating means associated with the main conductor between each pair of roof supports is provided for gradually reducing the main control signal to a value below said pre-determined value.
