摘要： A device for marking a wire projecting from the tube of a shell and tube heat exchanger includes first and second legs which cooperate to form a tubular body with opposed openings for receiving the wire, and a hinge at a first end of the tubular body about which the body flexes to enable insertion of the wire into the openings.

摘要： A device and method for dispensing catalyst pellets from a hopper to a chemical reactor. The hopper receives and holds the catalyst pellets at an elevation above the elevation of the chemical reactor. The flow of the catalyst pellets is controlled so they flow into and through a conduit in a widely spaced-apart arrangement to the chemical reactor. This controlled, spaced-apart flow is created by providing a sieve between a hopper and the conduit having openings small enough that the catalyst pellets form bridges above the openings, and then repeatedly breaking up the bridges in a controlled manner.
