  • Patent number: 9764505
    Abstract: Methods and devices are disclosed for providing the controlled formation of planar homogeneous or heterogeneous materials using microfluidic devices. In one embodiment, a planar array of microfluidic channels is employed to produce a flowing liquid sheet having heterogeneous structure by spatially and temporally controlling dispensing of polymer liquid from selected microchannels. The resulting liquid sheet is solidified to produce a planar heterogeneous material that may be continuously drawn and/or fed from the plurality of microfluidic channels. The polymer liquid may include a payload that may be selectively incorporated into the heterogeneous structure. In some embodiments, the local material composition is controllable, thereby allowing control over local and bulk material properties, such as the permeability and the elasticity, and of creating materials with directionally dependent properties.

  • Patent number: 8590567
    Abstract: A device to enhance sealing is provided. The device includes a body and a pressure cup. The pressure cup includes a channel, a first pressure channel, and a second pressure channel. The channel is formed in a surface of the body to surround a first portion of the surface. The channel is configured to hold an o-ring. The first pressure channel extends through the body and opens into the first portion of the surface. The second pressure channel extends through the body and opens into the channel. Pneumatic pressure within the second pressure channel is controlled to hold the o-ring in the channel when a second pressure within the first pressure channel changes.

  • Publication number: 20130284294
    Abstract: The invention relates to fluid actuator for influencing the flow along a flow surface through ejection of a fluid. By means of a like fluid actuator, a continuous flow is distributed to at least two outlet openings in order to generate fluid pulses out of these outlet openings. Control of this distribution takes place inside an interaction chamber which is supplied with fluid flow via a feed line. Into this interaction chamber there merge at least two control lines via control openings to which a respective different pressure may be applied. Depending on the pressure difference at the control openings, the flow in the interaction chamber is distributed to the individual outlet openings.

  • Patent number: 8539978
    Abstract: A valve unit for adjusting gas flow to a combustion apparatus includes a valve member that moves relative to a valve seat in response to a signal input to a coil, for varying a high-capacity gas flow rate through the valve unit. The valve unit includes a first opening port, a second opening port that is smaller than the first opening port, and a closure member. The closure member is movable between an open position, in which said high-capacity gas flow rate is communicated via the first and second opening ports to an outlet, and a closed position against the first opening port, in which a low-capacity gas flow rate is communicated via only the second opening port to the outlet. The valve unit includes a solenoid for selectively moving the closure member between the open position and closed position to selectively establish a high-capacity gas flow rate or low capacity gas flow rate.
