  • Patent number: 10043681
    Abstract: A fluid supply system includes a pressure tank configured to contain a pressurized gas and a fluid, a delivery point configured to be connected to a point of use, a recirculation piping connecting the pressure tank to the delivery point, and a return pump connected to the recirculation piping. The recirculation piping defines a circulation path for the fluid from the pressure tank through the delivery point and back to the pressure tank. The return pump is downstream of the delivery point and upstream of the pressure tank in the circulation path.

  • Patent number: 9632516
    Abstract: A gas-supply system includes a gas container filled with gas, a gas flow controller coupled to the gas container, and an operation device electrically connected to the gas flow controller. The gas-supply system further includes a buffer tank coupled to the gas flow controller and configured to receive the gas from the gas container via the gas flow controller. Furthermore, a pressure transducer disposed on the buffer tank and configured to generate a pressure signal to the operation device according to the pressure of the gas in the buffer tank. The operation device is configured to generate a control signal to the gas flow controller according the pressure signal, and the gas flow controller is configured to adjust the flow rate of the gas according to the control signal to keep the pressure of the gas in the buffer tank in a predetermined pressure range.

  • Publication number: 20090114657
    Abstract: A container includes a closed end, several first ring-shaped parts, and several second-ring-shaped parts adjoining the first ring-shaped parts; each of the first ring-shaped parts has a vertical annular side while each of the second ring-shaped parts has a sloping annular side; when the container is stretched, the ring-shaped parts will be one on top of another to comprise a substantially cone-shaped vessel, which can be pressed into a flattened shape with smaller ones of the ring-shaped parts being relocated within adjacent larger ring-shaped parts; the second ring-shaped parts are formed in such a manner that an angle between each of the second ring-shaped parts and a horizontal line is 60 to 80 degrees; thus, the container is more similar to a cylinder to have a large volume; therefore, the container can be pressed to become flat so as to occupy less space, thus being easy to carry and transport.
