  • Patent number: 9943786
    Abstract: A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid (e.g., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.

  • Patent number: 8957608
    Abstract: A motor-driving device of an electric caulking gun has a micro-controller unit (MCU), a direction-changing module, a motor and a speed sensor. The direction-changing module and the speed sensor are electrically connected to the MCU. The direction-changing module is electrically connected to the motor, and the speed sensor detects a speed of the motor. The MCU is built in with a speed determination procedure comparing an actual speed of the motor acquired from the speed sensor with a preset speed. If the actual speed is lower than the preset speed, it indicates that the resistance at a tube nozzle of the electrical caulking gun increases and the direction-changing module increases the speed of the motor to maintain a preset caulk discharge rate. Given the motor-driving device, the operational inconvenience arising from the unstable caulk discharge rate of conventional electric caulking gun can be tackled.

  • Patent number: 8915399
    Abstract: A medical fluid injection system may include a powered injector and a fluid reservoir that contains a simulated contrast medium. The simulated contrast medium may exhibit a fluid flow property substantially equal to that of an active contrast medium but be devoid of any active contrast agent that provides contrast during diagnostic imaging. During operation, a syringe in the powered injector may be filled with the simulated contrast medium and then evacuated to discharge the simulated contrast medium from the syringe. The simulated contrast medium may be used to test and evaluate the performance of the powered injector prior to use in a medical procedure without exposing personnel to an active contrast agent or creating medical waste that contains the active contrast agent.

  • Publication number: 20140339256
    Abstract: A system for dispensing a beverage includes a conical inner sleeve configured to receive a mixture of beverage components, a first blade, and a blade arm. An outer shell receives the first blade, blade arm, and the inner sleeve. A top couples the inner sleeve and outer shell in a fixed position. A tap module includes a tap handle and a tap control. The tap handle restricts and allows beverage flow through a beverage port. The tap control detects whether the tap handle is in a first position or a second position. The tap control prevents a motor from operation while the tap handle is in the first position and engages the motor while the tap handle is in the second position.

  • Patent number: 8881945
    Abstract: A method of operating a dispensing system includes the step of alternating between active and lockout modes within a first timing sequence, wherein during the active mode at least one sensor is active to detect sensory input, and whereupon detection of the sensory input results in product being released from a first container, and wherein during a lockout mode product is not released from the first container. The method further includes the step of alternating between active and lockout modes within a second timing sequence, wherein during the active period at least one sensor is active to detect sensory input, and whereupon detection of the sensory input results in fluid being released from a second container, and wherein during a lockout mode fluid is not released from the second container. The expiration of the first timing sequence, and the initiation of the second timing sequence, occurs from at least one of the lapsing of a time interval, sensory input, and manual input from a user.

  • Patent number: 8870548
    Abstract: Systems and methods for maintaining substantially a baseline pressure in a chamber of a pumping apparatus are disclosed. Embodiments of the present invention may serve to control a motor to compensate or account for a pressure drift which may occur in a chamber of the pumping apparatus. More specifically, a dispense motor may be controlled to substantially maintain a baseline pressure in the dispense chamber before a dispense based on a pressure sensed in the dispense chamber. In one embodiment, before a dispense is initiated a control loop may be utilized such that it is repeatedly determined if the pressure in the dispense chamber is above a desired pressure and, if so, the movement of the pumping means regulated to maintain substantially the desired pressure in the dispense chamber until a dispense of fluid is initiated.

  • Patent number: 8851111
    Abstract: The controller of the plural component proportioner (10) dispenses both components (or all three if a three component material) simultaneously (at least initially) and maintains ratio at the end of each predetermined volume of material by determining which component pump (12) has reached the desired amount of travel (given the resolution available) and using a valve (16) to shut off output of that pump until the other side has caught up. At pump changeover, the output valve for that pump (12) is shut off and the air motor (12a) allowed to run until travel stops to account for cavitation, air entrainment, compressibility, or poor inlet check performance.

  • Publication number: 20140263416
    Abstract: An apparatus for controlling a fluid flow may include a flow channel, a housing, a flow restrictor, and a housing adjustment member. The flow channel defines a fluid pathway for the fluid flow. The fluid pathway includes an inlet and an exit. The housing surrounds the flow channel. The housing comprises an exterior surface defining a first threaded portion. The flow restrictor is located within the housing and proximate the exit. The housing adjustment member includes a second threaded portion in contact with the first threaded portion. Embodiments may include a method for controlling a fluid flow. The method comprises: causing the fluid flow to pass through a flow channel having an inlet and an exit; restricting, via a flow restrictor, the fluid flow, the flow restrictor located proximate the exit; and adjusting a position of the flow restrictor to further restrict or unrestrict the fluid flow.

  • Patent number: 8814536
    Abstract: Embodiments of the invention provide a system, method and computer program product for reducing the hold-up volume of a pump. More particularly, embodiments of the invention can determine, prior to dispensing a fluid, a position for a diaphragm in a chamber to reduce a hold-up volume at a dispense pump and/or a feed pump. This variable home position of the diaphragm can be determined based on a set of factors affecting a dispense operation. Example factors may include a dispense volume and an error volume. The home position for the diaphragm can be selected such that the volume of the chamber at the dispense pump and/or feed pump contains sufficient fluid to perform the various steps of a dispense cycle while minimizing the hold-up volume. Additionally, the home position of the diaphragm can be selected to optimize the effective range of positive displacement.
