Abstract: The invention relates to an electrical switching device including a nominal contact arrangement, an arcing contact arrangement defining an arcing volume in which an arc-quenching medium is present, an exhaust system including a first exhaust opening connected fluidly to a tank volume, an exhaust channel for dissipating hot medium from the arcing volume into the tank volume, the exhaust system further including a piston arranged in a compression guide and defining on its side opposed to the arcing volume together with the compression guide a compression chamber. An inlet channel is fluidly connected to the compression chamber and extends to an inlet opening fluidly connected to the tank volume, wherein the inlet channel and the exhaust channel are fluidly separated from each other.

Abstract: Apparatus for cooling products includes a cooling chamber with a conveyor for conveying the products through the chamber, at least one circulator for circulating a cooling gas within at least a part of the chamber, a first guiding element for guiding the cooling gas on a first conveyor side, and a second guiding element for guiding the cooling gas on a second conveyor side, wherein the first and second guiding elements are arranged within the chamber such that the cooling gas can impinge the first side, and the first and second guiding elements are oriented obliquely compared to the conveyor.

Abstract: An apparatus for cooling products includes a cooling chamber with a conveyor for conveying the products through the cooling chamber, at least one circulator for circulating a cooling gas within at least a part of the cooling chamber, and guiding elements for guiding a flow of the cooling gas. The guiding elements are arranged such as to form at least one backflow channel from the second side of the conveyor to the at least one circulator, and wherein the cooling gas can be directed into an impingement section via the at least one circulator.

Abstract: Apparatus for cooling products including a cooling chamber with a conveyor for conveying the products through the chamber, at least one circulator for circulating a cooling gas within at least a part of the chamber, and a first aperture element with a plurality of first aperture openings. The conveyor and the at least one circulator are arranged within the cooling chamber such that the cooling gas can impinge a first side of the conveyor, wherein the first aperture element is arranged within the chamber such that the cooling gas penetrates through the first aperture openings before impinging the first side of the conveyor.

Abstract: In various embodiments, fluid conduits such as high pressure hoses deployed in-between two sea-fairing vessels may be released during an emergency by using a rapid release emergency disconnect system as described herein, where the rapid release emergency disconnect system may engage with a hanger such as an industry standard frac hanger and be used in-line with fluid conduits such as high-pressure lines. Various skid embodiments are described which can be configured to interface with one or more of the described rapid release emergency disconnect systems.

Abstract: A subsea well assembly has a tubing hanger that lands and seals in a wellhead housing. A tree block is lowered through the drilling riser into engagement with the tubing hanger. The tree block has a lower portion that inserts and latches into the bore of the wellhead housing. The drilling riser is disconnected, and a module is lowered onto the tree block, the module having a choke and controls for controlling the well. The master valve for production is the downhole safety valve in the tubing. The wing production valve is a ball valve located in the flow passage of the tree block.

Abstract: A hang tag is disclosed. The hang tag has first and second surfaces, which are preferably planar. A slot is defined between the first and second surfaces. Desirably, the slot extends at least about 0.25 inches in one direction and at least about 1 inch in another direction. Also disclosed is a method and an apparatus for automatically applying a hang tag to an elongated object (e.g., an electrical cord such as a cord set), with a machine that is suitable for applying a securement strap to an object. The method includes providing a hang tag having a slot therein. The hang tag is aligned with the machine so that when the securement strap is ejected from the machine, it passes through the slot, forms a loop around the elongated object, and is tensioned around the object. As such, the securement strap serves to attach the hang tag to the elongated object in a stationary manner.
