摘要:
The concepts relate to reducing energy loss associated with hot water systems. One example can monitor hot water use in a system. Upon completion of the hot water use, the example can recover some of the hot water from hot water lines into a water heater that heated the hot water. The method can also deliver the recovered hot water to the water heater in a manner that affects operation of a heating element of the water heater.

Vascular treatment devices and methods include a woven structure including a plurality of bulbs that may be self-expanding, a hypotube, for example including interspersed patterns of longitudinally spaced rows of kerfs, and a bonding zone between the woven structure and the hypotube. The woven structure may include patterns of radiopaque filaments measurable under x-ray. Structures may be heat treated to include various shapes at different temperatures. The woven structure may be deployable to implant in a vessel. A catheter may include a hypotube including interspersed patterns of longitudinally spaced rows of kerfs and optionally a balloon. Laser cutting systems may include fluid flow systems.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

A reservoir for one or more chemical reactants has means for heating the reactants and optional means for stirring the reactants. A pumped reactant feed line and a return line provide fluid communication between the reservoir and a 4-way valve system. The 4-way valve system is also in fluid communication with a reactor vessel and a source of inert gas for purging the system. In a first state, the 4-way valve provides fluid communication between the reservoir and the reactor. In a second state, the 4-way valve provides a continuous circulation path for the heated reactants from the reservoir, to the valve system, and back to the reservoir via the return line. In a third state, the 4-way valve provides a fluid pathway for purging the reactor with inert gas. In a fourth state, the 4-way valve provides a fluid pathway for purging the reservoir with inert gas.

A cutting fluid tank includes: a fluid ejection apparatus configured to eject fluid toward cutting fluid containing chips and to be capable of varying at least one of a direction and a position of ejection with time in an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The fluid ejection apparatus includes an ejection head having an ejection port rotatable about an axis of rotation. The ejection port is at a twisted position with respect to the axis of rotation, and the ejection head is rotated by a reaction force of the fluid ejected from the ejection port. Part of the cutting fluid stored in the cutting fluid tank is used as the fluid to be ejected from the ejection port.

A subsea system is for uptake and supply of a liquid. The system comprises a storage tank having at least one outlet, a valve assembly, a pump having a high-pressure side and a low-pressure side, and a feed line. The outlet is in fluid communication with a lower internal volume of the tank, and the valve assembly. The low-pressure side of the pump and the feed line are in fluid communication with the outlet, and the valve assembly is arranged on the feed line, and the feed line is bypassing the pump, such that said pump may withdraw liquid from the tank when the valve assembly on the feed line is closed.
