Abstract: Tankless evaporators, refrigeration circuits, and water coolers use a drum as a thermal mass without using one or more tanks for storing water. Water coolers can include a tankless evaporator. Also described are refrigeration circuits suitable for a water cooler and which include a tankless evaporator. An evaporator for use in a fluid chiller includes a drum of heat conductive material defining a thermal mass, a water coil disposed adjacent around the drum, an evaporator coil configured around the drum and adjacent to the water coil, in which the evaporator coil is operative to cool the water coil.

Abstract: A wall mounting system is described having a wall mounting bracket to be rigidly secured to a wall, a pair of water bottle filling station-mounted brackets to be rigidly secured to a water bottle filling station, and a pair of bracket adaptors, each configured to be secured to a respective one of the water bottle filling station-mounted brackets and to the wall mounting bracket. The system can include one or more springs. The system allows an operator to properly install a water bottle filling station on uneven walls or damaged or improperly installed wall mounting brackets.

Abstract: A malleable metal straw. The malleable metal straw has an elongated member with a metal sidewall and a first open end and a second open end. An interior region has a liquid permissible cavity from the first open end to the second open end wherein at least a portion of the metal sidewall is sufficiently thin to allow the elongated member to bend under hand strength force. The malleable metal straw can further have a support structure within the interior region.

Abstract: Tankless evaporators, refrigeration circuits, and water coolers are described, which use a drum as a thermal mass without using one or more tanks for storing water.

Abstract: A completion system for a well includes a tubing hanger movable into a landed position within an internal bore of the completion system. The tubing hanger includes a hanger bore formed through the tubing hanger, an auxiliary passage formed through the tubing hanger outside of the hanger bore, and a shuttle rod valve including a rod movable in a cavity that is capable of being in fluid communication with the auxiliary passage to control the flow of fluid through the auxiliary passage.

Abstract: A production assembly for a subsea well, the assembly comprising a tubing hanger landed in the production assembly, the tubing hanger suspending production tubing from the production assembly, an annulus surrounding the production tubing, and an actuatable rotary disc valve comprising a disc and two seats, wherein the disc is rotatable between two seats to an open position in which one or more apertures in the rotary disc valve are aligned with one or more apertures in the seats, and a closed position in which the one or more apertures in the rotary disc valve are offset from the one or more apertures in the seats, wherein, the annulus is not capable of fluid communication through the tubing hanger when the actuatable rotary disc valve is in the closed position.
