  • Patent number: 10197047
    Abstract: A hydraulic proportioning system has a flow divider providing hydraulic fluid to drive two hydraulic pumps. The flow divider provides set amounts of hydraulic oil to each of two pumps, and the pumps each provide one material of the plural component material downstream to a mixing manifold. The two materials are mixed at the mixing manifold before application. The flow divider drives each pump at a set speed depending on the volume of hydraulic oil provided to each pump. The flow divider thus determines the ratio of the first material to the second material provided to the mixing manifold by the pumps.

  • Patent number: 9079142
    Abstract: A device is designed to be coupled to a fluid supply at a first inlet, to a fluid exhaust path at an outlet, and to an additive source at a second inlet. An inlet stream of working fluid is mixed with the additive in a mixing chamber and an outlet stream of the mixed fluid exhausts from the device. The device uses a hydraulic pump employing a valve mechanism that cycles and ports the flow of fluid through the device and allows for the mixing of the working fluid in the mixing chamber. The valve mechanism is spring actuated by a linkage mechanism employing a push-pull linkages tensioned by a spring. The mixing action allows a specific quantity of additive to mix with the working fluid in the mixing chamber of the device. Thus, the outlet stream provides a mixture of a predetermined concentration of whatever additive is used.

  • Patent number: 8640729
    Abstract: An automatic shut-off valve shuts off fluid flow in the event of abnormal amounts of fluid flow. A rotor inside the valve turns when fluid flows through the valve. The rotor causes a pneumatic pump to operate and cause increased air pressure. The increased air pressure causes a shut-off piston to move to a closed position when a predetermined air pressure is achieved. The shut-off valve also includes an adjustable bleeder needle to slowly bleed off air pressure when the fluid flow stops and thereby resets the valve. A detent is provided for holding the shut-off piston in the open position. A detent spring and compression bolt are provided for adjusting force on the detent. The shut-off valve is manually closed using a trip arm connected to the detent. The shut-off piston is reset by actuating a reset plunger that moves the piston back to the open position.

  • Patent number: 6769449
    Abstract: Water is first caused to flow through a first passage and rotate a first impeller. Rotation of the first impeller is linked to rotation of a second impeller, which is in fluid communication with a second, discrete passage. Vanes on the second impeller are constrained to move faster than vanes on the first impeller. Water is subsequently caused to flow through the second passage and to be more aggressively advanced by the second impeller.

  • Publication number: 20020166586
    Abstract: A fluid metering device that preferably includes a substantially linear series of intermeshing gears. The fluid metering device includes an inlet port adjacent the intermeshing portion of each pair of gears within the series adjacent the point at which the pair of gears diverge. The device further includes an discharge port adjacent the intermeshing portion of each pair of gears within the series adjacent the point at which the pair of gears converge. The device is configured to convey liquid from a main inlet stream of liquid, through the inlet ports, and out the discharge ports at substantially equal rates. The device preferably includes a pressure balance inlet port and a pressure balance discharge port adjacent the exterior portion of each end gear within the series of gears for balancing forces exerted on the end gear by liquid passing through the various inlet and discharge ports.

  • Patent number: 6299657
    Abstract: In the reaction process, at least two educts A, B are divided by a system, assigned to each of them, of slit-like microchannels 1a, 1b into spatially separate fluid lamellae, which then emerge into a common mixing and reaction space 4. The fluid lamellae here have a thickness <1,000 &mgr;m, preferably <100 &mgr;m, at a width thickness ratio of at least 10. It is essential here that educts A, B can emerge as thin fluid lamellae 6a, 6b into the mixing/reaction space 4, each fluid lamella 6a of an educt A being led into the mixing/reaction space 4 in the immediate vicinity of a fluid lamella 6b of another educt B. The adjacent fluid lamellae 6a, 6b then subsequently mix by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially compared with conventional reactors. In the case of rapid chemical reactions, the formation of undesirable by-products or secondary products is largely prevented in this manner.

  • Patent number: 6135719
    Abstract: A system for metering a fluid, such as a catalyst in an industrial chemical process plant, includes a controller, a drive pump assembly and an injection pump assembly. The drive pump assembly forces reciprocation of the injection pump assembly via a controlled flow of hydraulic fluid. The injection pump assembly includes a drive cylinder and at least one injection section. The drive cylinder receives pressurized fluid from the drive pump assembly and causes metered fluid to be drawn into and expelled by the injection section. The position of reciprocating components of the injection pump assembly is detected between stroke limits and converted to a velocity signal. Closed-loop control of the flow from the injection pump assembly is implemented by the controller via the drive pump assembly based upon the actual velocity of the reciprocating components of the injection pump assembly and a commanded velocity.

  • Patent number: 5896881
    Abstract: The process and device according to the invention make it possible to reduce the pressure build-up in the head space as a function of the quantity of inflow medium. It also makes it possible to maintain or create defined flow conditions in the head space gas. This is accomplished by measuring the quantity of gaseous and/or liquid inflow medium and then venting the head space gas as a function of the quantity of inflow medium.

  • Patent number: 5588088
    Abstract: A hot water tempering system tempers the output of a hot water storage tank by mixing that output with a cold water flow in a defined ratio to produce a flow of water at a steady intermediate temperature. The system comprises a bypass line connectable between an inlet line and an outlet line of the storage tank, and a proportional flow controller for controlling the relative water flow rates through the tank and through the bypass line. The flow controller may be positioned on the inlet line and the bypass line, or on the outlet line and the bypass line. The tempering system allows the temperature of water in the storage tank to be maintained near the boiling point for killing organisms, but at the same time ensures that water leaves the system at a temperature sufficiently low to be safe for human use.

  • Patent number: RE35780
    Abstract: The present invention is a post-mix beverage dispensing valve for accurately maintaining the proper ratio of two liquid beverage components. The present invention includes a valve main body having a gear pump secured thereto. The gear pump includes two sets of oval gears. One set of oval gears is in fluid communication with a source of pressurized carbonated water, and the second set is in fluid communication with a source of syrup. The valve body also includes solenoid operated pallet valves for each of the beverage components. Ratioing of the solenoid provides for simultaneous opening of both pallet valves whereby the pressurized carbonated water flows between the carbonated water gears and is swept thereby through the valve body to the dispensing nozzle. One gear of each gear pair is secured to a common rotating shaft. Pressurized carbonated water provides for the rotation of the syrup gears, thereby providing for the pumping of the syrup to the nozzle.
