Abstract: An apparatus for creating a flow of gas comprises a frame having a passage defined therethrough. The passage extends a length along a central longitudinal axis from an inlet to an outlet and has a first side and a second side. A flexible pumping membrane is disposed within the passage. The membrane has a first edge coupled to the first side of the passage at a midline thereof and a second edge, disposed opposite the first edge, coupled to the second side of the passage at a midline thereof. The membrane segregates the frame into an upper portion and a lower portion. The apparatus also includes an actuating system which is structured to selectively move portions of the membrane toward either the upper portion or the lower portion of the frame in a manner which causes a wave-like movement in the pumping membrane and creates the flow of gas.

Abstract: A magnetorheological support method for blisk processing is disclosed. In the method, a fork structure and a soft film are used to wrap magnetorheological fluid. The magnetorheological fluid is used for flow filling under certain pressure. The bulged soft film can conduct shape matching on the surface of a blisk blade. The magnetorheological fluid can be cured through magnetic field excitation, thereby ensuring the flexible support for a weak rigid component. Electric permanent magnets are symmetrically arranged at both ends of the fork structure to construct a uniform magnetic field that can realize a global excitation of magnetorheological fluid, so that the magnetorheological fluid works in a shear mode to achieve damping force controlling by magnetic field. The solid-liquid conversion of the magnetorheological fluid is controlled by an electric permanent magnet field.

Abstract: A pump assembly includes a chamber, a compressible conduit along a periphery of the chamber, an elongated sun member within the chamber, and an elongated planet member arranged to orbit around the sun member. The sun member includes a first portion at one axial end having a gear and a second portion at the other axial end. The planet member includes a first portion at one axial end with a gear engaged with the gear of the sun member and a second portion at the other axial end configured to be engaged with a section of the compressible conduit to constrict the section. The first portion has a different texture from the second portion, and teeth of the gears on either the sun member or the planet member are retained in an axial direction by the second portion of the other of the sun member and planet member.

Abstract: A method for operating a device configured to provide a dosed supply of a liquid. The device has: a pump delivering the liquid and having a pump housing having an inlet and an outlet, an eccentric on the pump housing, and a deformable diaphragm arranged between the pump housing and the eccentric. The deformable diaphragm and the pump housing delimit a delivery path from the inlet to the outlet and form at least one seal of the delivery path, the seal being displaceable along the delivery path by a movement of the eccentric to deliver the liquid. The method comprises: detecting a demanded dose amount of the liquid; activating the pump to deliver the liquid by the pump; stopping operation of the pump when the delivered amount of the liquid corresponds to the demanded dose amount; deactivating the pump when the eccentric is situated in a predefined park position.

Abstract: A peristaltic pump device includes a resilient tube secured in a pump housing with a rotor having rollers squeezing against the resilient tube facilitating the pumping of a liquid or gas. A cylindrical rotor rotates in a bore provided in the pump housing. The rotor has steps in which rollers freely slide and rotate. As the rotor rotates, the rollers also rotate and are slidingly held in the rotor step thereby frictional contact with the compressing resilient tube and consequently the liquid or gas within goes out of the resilient tube. The pump is inexpensive to build, reliable, and by design promotes the long life of the resilient tube as compared to existing roller type peristaltic pumps.

Abstract: A wheel mounted control assembly receives therethrough the tire valve stem from an air maintenance tire. A control assembly regulator controls a flow of air to and from a tire-mounted air pumping tube. The control assembly includes a bi-directional air distribution flow control system having multiple parallel air pathways, each air pathway coupled to a respective conduit connected to an air pumping tube mounted within a tire sidewall. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

Abstract: A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.

Abstract: A conveying device with peristaltic movement includes a flexible transport tube and a two-way shape memory alloy. The two-way shape memory alloy is mounted on the surface of the transport tube. When the two-way shape memory alloy is electrically conducted and heated, the cross-sectional area of transport path in the flexible transport tube contracts by the contractive force resulting therefrom. When electrically conducting and heating the two-way shape memory alloy is terminated, the original cross-sectional area of transport path in the flexible transport tube is restored by the recovery force thereof. The position of the flexible transport tube at which the contraction and the restoration are applied to is sequentially moved in a predetermined direction by a temperature controlling device, so as to convey an object within the flexible transport tube in the predetermined direction.
