    Abstract: According to an embodiment, there is provided herein a method of determining the air void distribution in a sample of fresh concrete. One embodiment of the invention determines a parameter related to air void distribution by applying a known pressure to a fresh concrete sample, measuring a first value representative of the volume under compression, releases at least a portion of the pressure, reapplies the same pressure to the sample, measures a second value representative of the volume under the second compression, and uses differential between the first and second values to estimate a parameter related to the air void distribution.

  • Patent number: 9188992
    Abstract: A water tank has a container, a micro switch, a limiting assembly and a float. The float is mounted slidably in the container. The limiting assembly has an actuating rod that slides in a direction perpendicular to the sliding path of the float. An inclined guiding track is mounted between the float and the actuating rod to convert the moving direction. Since the actuating rod utilizes the movement to switch the micro switch on and off, the actuating rod and the micro switch need no abutting structures. Therefore, when the actuating rod is moved by an accidental force, the actuating rod self-moves back to its original position once the accidental force is removed. Then the micro switch is switched on again so that the household appliance is restarted without any extra acts by a user.

    Abstract: A system and method for improving oil-and-water separation in a blended fluid stream are presented. The system includes a pressure reduction device that causes cyclonic flow in the stream. The pressure reduction device may be a wafer-based hydrocyclone or a modified hydrocyclone having an underflow outlet but no overflow outlet. The system may also include a valve that is located upstream or downstream of the pressure reduction device. Both the valve and the pressure reduction device reduce the pressure of the fluid stream while reducing the shearing of oil and water droplets within the stream. As a result, the droplets are more likely to coalesce and less likely to form emulsions, thus improving oil-and-water separation in downstream treatment processes.

  • Patent number: 8550288
    Abstract: A beverage container with an electronic display device and methods for its use are described. The beverage container includes an electronic display device disposed in a sidewall of the container and a control module disposed in a hollow base portion. A liquid sensor senses the presence of a liquid in the container and a motion sensor is provided to sense movements of the container caused by, for example, transporting, holding, or drinking from the container. When the control module receives appropriate signals from the liquid and motion sensors an image or video is displayed on the display device. The container is thus useable to display pictures, videos, slide shows, advertisements, or the like in personal or commercial applications. A communications port is also provided to enable coupling of the container with a computing device for management of images and videos displayed on the container.

  • Publication number: 20130255797
    Abstract: A method for venting of a liquid tank with a valve, a primary compartment and a secondary compartment which are connected together via a bridge. The valve includes a chamber provided with a cover, which extends at least partly into the tank and is connected via an upper venting aperture to a venting circuit. A first device monitors a level of liquid in the primary compartment. A second device monitors a level of liquid in the secondary compartment. The valve configured to be closed when the first device detects that the level of liquid in the primary compartment is equal to or higher than a first predetermined filling level, and the second device detects that the level of liquid in the secondary compartment is equal to or higher than a second predetermined filling level.

  • Publication number: 20130256062
    Abstract: A lubricant reservoir system. The system includes a reservoir for containing lubricant. The reservoir has a top, a bottom, a peripheral wall, and an inlet for delivering lubricant to the reservoir from a supply. The system also includes a follower in the reservoir slidingly and sealingly engaging the peripheral wall of the reservoir, the follower moving up and down in the reservoir in response to a changing level of lubricant in the reservoir. The lubricant reservoir system has a shut-off valve in fluid communication with the inlet for selectively preventing lubricant flow through the inlet. The valve is operatively connected to the follower for closing the valve and preventing lubricant flow through the inlet when lubricant in the reservoir reaches a predetermined level.

  • Publication number: 20130192680
    Abstract: A measurement device for regulating the filling level of a liquid-gas mixture via a inlet valve in a container, having at least one vertical liquid standpipe fixed to a outer wall of the container and fluidically connected to the interior of the container via horizontal tube-shaped hydraulic devices. A first lower hydraulic device is disposed near the container base so the standpipe level changes with the container. A second hydraulic device is provided above the desired filling level so that the standpipe level changes when a selectable desired filling level value is exceeded. The device has a display and regulator that is in controlled connection to the liquid inlet valve. The liquid standpipe has a third tube-shaped hydraulic device that protrudes horizontally into the container and is arranged in the container at or below the desired filling level. The first lower hydraulic device is configured as a return.
