A vent structure for large volume liquid storage tanks having a double gooseneck shape with vent openings facing downward, formed as a single structure from a mold tool with multipart extractable cores for forming the structure from corrosive resistant materials without a need for substantial post machining.

A system for remotely opening an access hatch of storage tank includes an elongate arm having a proximal end configured to be operatively coupled to a lid of the access hatch and a distal end extendable past an outer perimeter of the storage tank, and a pull cable attached to the arm at the distal end and being extendable toward a ground surrounding the storage tank. Pulling on the pull cable releases a latch that secures the lid to a base of the access hatch and allows the lid to pivot from a closed position to an open position.

A storage tank includes a floor, a roof, a sidewall extending between the floor and the roof, an access hatch provided on the roof and having a base, a lid pivotably coupled to the base, and a latch configured to secure the lid to the base in a closed position, and a system for remotely opening and closing the access hatch. The system includes an elongate arm having a proximal end operatively coupled to the lid, a pull cable attached to a distal end of the elongate arm and extending toward a ground adjacent the storage tank, and a latching cable attached to the latch and extending toward the ground adjacent the storage tank, wherein pulling on the latching cable when the lid is in the closed position actuates the latch to secure the lid to the base in the closed position.

An equipment asset may include a body, one or more current collector rails, and a grounding element. The body may have a top side and a power transfer zone. The power transfer zone may include at least an electrically non-conductive top surface. The one or more current collector rails may be mounted to the top side of the body within the power transfer zone. The grounding element may be electrically conductive and disposed on the top side of the body. The grounding element may surround the power transfer zone and be spaced apart from the one or more current collector rails. The grounding element may receive liquid that is runoff from the power transfer zone and electrically ground charged portions of the liquid.

Systems and methods relating to the safety of railway cars carrying flammable materials. A rail tank car having an inner tank and an outer protective wall surrounding the inner tank is provided. The outer surface of the inner tank and the inner surface of the outer protective wall are separated by a gap. A low emissivity coating is applied to one or both of the outer surface of the inner tank and the inner surface of the outer protective wall. Existing rail tank cars with a similar construction can be retrofitted by spraying the low emissivity coating inside the gap to thereby coat at least one of the inner surface and the outer surface. Preferably, the low emissivity coating has an emissivity coefficient of, at most, 0.8.

The present disclosure provides a transport case, which includes a case body, the case body being internally provided with a containing space for containing materials; the case body includes a supporting framework and a protective coating, the supporting framework being coated with the protective coating, wherein the supporting framework is made of a metal material, and the protective coating is made of a plastic material. The problem in the art known to inventors of low pressure bearing capacity of the transport case is solved.

Disclosed is a method for manufacturing a container for cooling a technical device, in particular a test bench for a technical component, preferably for a compressor, and/or a battery storage device. The method can include a freight container and integrating a cooling device for cooling a cooling liquid into the freight container.
