    Abstract: An aseptic filling machine capable of performing molding and filling at the same time that has a compact facility size, requires a reduced initial investment, requires a reduced running cost because of its simplified process, and ensures an aseptic condition with reliability, and an aseptic filling method therefor. An aseptic filling machine includes a pre-heating sterilizing portion that sterilizes a preform, a heating portion that heats the sterilized preform, a molding and filling portion that fills the heated preform with a sterilized content under high pressure, thereby molding the preform into a bottle and at the same time filling the preform with the content, and a sealing portion that seals the bottle filled with the content. Before the aseptic filling machine starts operating, each portion is sterilized. During operation of the aseptic filling machine, aseptic air is supplied to each portion to maintain the aseptic condition.

  • Patent number: 11634884
    Abstract: Water Reservoirs and wetlands are a major source of methane emissions contributing to greenhouse gases. The annual flood seasons contribute to movement and accumulation of sediments behind irrigation and hydropower dams. These sediments accumulate year after year, lead to loss of water storage capacity and ability to produce hydro-electricity. The invention being proposed to dredge deep sediments from reservoirs operates on the principle of using gaseous fuel from an external pipeline or collected methane emissions as fuel for a submersible internal combustion slurry system. The invention combines the features of an internal combustion liquid piston engine with a slurry turbine driving a dredging cutter. Slurry entering into the system forms a column that is set in oscillation through the explosion of air and fuel and is then pumped to shore.

  • Publication number: 20140377084
    Abstract: A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

A first valve controls a first fluid communication between the pumping chamber and the external environment, and a second valve controls a second fluid communication between the pumping chamber and the fluid container. The pumping chamber and the valves cooperate to generate a vacuum and a negative potential pressure of the gas inside the pumping chamber by the effect of the gas temperature alternation when the gas passes from a heated state to a cooled state and by controlling the first and second fluid communications. The generated vacuum and negative potential pressure inside the pumping chamber enable pumping of the fluid from the fluid container inside the pumping chamber.

  • Patent number: 8641386
    Abstract: A method of pumping a liquid using at least one operating tank (2), a pneumatic positive pressure displacement pump (1), which is based on the fact that during pumping, inflow valve (4) closure is controlled through the introduction of a control gas into the operating tank (2) positive pressure displacement pump (1) at a pressure lower than the pressure of the compressed actuating gas and from the hydrostatic pressure at the egress of the outflow valve but higher than the hydrostatic pressure on the ingress into the inflow valve (4), which causes the inflow valve (4) to close. A device for pumping liquids comprising at least one operating tank (2) of a positive pressure displacement pump (1), to which leads a control gas conduit (10) with a control valve (11) mounted thereon, which is used to close off the inflow valve (4), and the lower section of the operating tank (2) has a narrow section in the form of a vertical cylinder (16).

  • Patent number: 8607877
    Abstract: This invention relates to equipment and a subsea pumping system using a subsea module installed on the sea bed, preferably away from a production well and intended to pump hydrocarbons having a high associated gas fraction produced by one or more subsea production wells to the surface. One object of this invention is achieved by means of the design of a pumping module (PM) which is linked to pumping equipment already present in a production well and which basically comprises: an inlet pipe (2), separator equipment (3), a first pump (4) and a second pump (8). In the subsea pumping system for the production of hydrocarbons with a high gas fraction, the other object of this invention, when oil is pumped from the production well (P) the well pump (13) increases the energy of the fluid in the form of pressure and transmits this increase in energy in the form of an increase in suction pressure in the second pump (8) of the subsea module (PM).

    Abstract: Described are a gradient system and method, wherein at least two fluids are mixed in accordance with a noise level threshold. An inlet receives the fluids. A pump head body has a mixing chamber therein in communication with the inlet. The mixing chamber has a first delay volume configured to mix the fluids having a noise level. A pump head extension has a mixing chamber extension therein extending from the mixing chamber. The mixing chamber extension increases the volume of the mixing chamber by a second delay volume to a third delay volume. The fluids are mixed in the third delay volume at a compositional noise level that is less than the noise level.

  • Publication number: 20130266456
    Abstract: A buoyant force pump and surge apparatus is disclosed. A material which is buoyant relative to a non-solid material is used to cause a movable surface to move thereby causing the non-solid material to be pumped in surges. One use of the device is to create water surges in aquariums through the use of conventional low pressure, low volume air pumps and without the need for mechanical pumps or control electronics. A second use of the device is to move non-solid material in hazardous conditions.

    Abstract: A vacuum prioritization system for a vehicle is disclosed. In one example, use and availability of vacuum provided via vacuum sources is allocated to higher priority vacuum operated actuators when a pressure in the vacuum system exceeds a threshold pressure. The lower priority vacuum operated actuators have access to vacuum supplied via the vacuum sources when pressure in the vacuum system is less than a threshold pressure. The approach may allow higher priority actuators to operate for an extended amount of time.
