摘要： A method and mechanism for initiating an emergency stop for an unattended railcar is disclosed. The method may include using a trip arm placed alongside the railway tracks at a designated stop point that may contact a portable trip-cock lever arm that extends out beyond the perimeter of the railcar if the railcar reaches the stop point as it moves along the track. The trip-cock lever arm may be attached to a valve that is connected to the pneumatic brake system of the unattended railcar. As the trip-cock lever arm rotates, the valve may open to release the air pressure in the pneumatic brake system causing the brakes to engage the wheels causing the railcar to stop.

摘要： A method and system for detecting sulfur fires that comprises a remote infrared or microwave sensor to detect sulfur dioxide gas and provide an unsupervised remote daytime and nighttime sulfur fire-watch, hot spot detection, early sulfur fire prevention, sulfur fire detection, or sulfur fire control of unattended combustible sulfur blocks, sulfur stockpiles, sulfur plants, or equipment using remote sensing devices that includes detection, measurement and analysis of electromagnetic radiation to determine the presence of sulfur dioxide gas.

摘要： The present invention is concerned with degassing processes, and more specifically with a degassing apparatus and method for removing hydrogen sulfide and hydrogen polysulfides from liquid sulfur in a rapid and efficient manner to result in low residual hydrogen sulfide and hydrogen polysulfide levels. Utilizing a rotodynamic degassing pumping unit, a first fluid, typically in the liquid phase, is pumped or drawn under pressure or vacuum, while a second fluid, typically in a gaseous phase, is pumped or drawn under pressure or vacuum into the first fluid, effecting a chemical reaction. A rotary impeller having a plurality of blades is presented at a submerged location in the liquid sulfur surrounded by a draft-tube. The rotor (impeller) is divided into three distinct blade sections: a) a radial flow section; b) a mixed flow section; and c) an axial flow section. An overflow weir controls the depth of the liquid inside the degasser's housing. The overflow weir includes a corrugated type cross-section, comprising segments split longitudinally and welded lengthwise. The “wavy” or sinusoidal cross-sectional shape or trapezoidal or triangular shape (extending radially inwards) increases the length of the weir, which in turn minimizes the head required, and maximizes the capacity. A novel rotor bearing design is introduced as a means to mitigate excessive deflection of the main shaft. The design removes one of the two rotor bearings of the prior art and places two immersed bearings down the shaft.
