The present invention is directed towards an apparatus and methods for a precise, fast and easy to use manipulation of beads. This method is particularly useful to carry out separation between the beads and the remaining supernants present in the fluid, maximizing the collection and purification efficiencies in tips for liquid handling.

Devices and methods are provided for in-line water treatment using strong magnetic fields to influence corrosion, separate toxins, suppress bacteria and bio-fouling, as well as inhibit or greatly reduce mineral scaling due to fluid flow in or around equipment components. For example, a device is provided for applying a magnetic field to a portion of tubing through which a fluid flow, such as water, is conveyed. The device includes a number of links joined together via detachable pivoting connections, such that links may be removed and/or links may be added, thereby allowing a diameter of the device to be adjusted so as to accommodate larger or smaller piping, as necessary, for retrofitting applications. The use of magnetic treatment of fluids such as water may allow extended cycles of operation with higher concentration of mineral salts without the use of chemical scaling suppressants.

A magnet apparatus for generating a high gradient and/or high strength magnetic field, comprises: two permanent magnets (2, 4) located side-by-side with oppositely oriented magnetic field polarities and end surfaces of opposite polarities next to one another, wherein the magnetic anisotropy of the magnets exceeds the magnetic induction of the material of the magnets; and a mask (6) or masks (6) on a first end of each of the adjacent permanent magnets (2, 4), the mask(s) 6 comprising a non-retentive material covering adjacent end surfaces of the two permanent magnets (2, 4) with a gap (8) along a joining line between the two permanent magnets (2, 4) to form a zone of high-gradient magnetic field above the joining line; wherein the mask(s) (6) are embedded within the magnets (2, 4) and/or have a varying thickness and wherein the mask(s) (6) each have a maximum thickness greater than a tenth of the thickness of the respective magnet (2, 4).

An oil tank cleaning ball serves for attracting metal impurities within an oil tank, and has a function of checking whether the oil tank is dirty. The oil tank cleaning ball comprises an enclosing body made of non-magnetic material, but the magnetic lines can pass through the enclosing body, an outer surface of the enclosing body being uneven and rough, having sags and crests so as to expand an area of the outer surface for attracting impurities; a magnetic metal sheet enclosed within and fixed by the enclosing body; the magnetic lines emitting from the magnetic metal sheet can pass through the enclosing body so as to attract the impurities within the oil tank. Amount of impurities on the oil tank cleaning ball is used to decide whether an interior of the oil tank is dirty.

An engine air intake dust removal system and method, comprising an air intake dust removal system inlet (1011), an air intake dust removal system outlet and an air intake electric field device (1014). The air intake dust removal system (101) and method can effectively remove particulate matters from air trying to enter the engine, and make the air entering the engine cleaner.

A system and method in at least one embodiment for separating fluids including liquids and gases into subcomponents by passing the fluid through a vortex chamber into an expansion chamber and then through at least a portion of a waveform pattern present between at least two rotors and/or disks. In further embodiments, a system and method is offered for harnessing fields created by a system having rotating rotors and/or disks having waveform patterns on at least one side to produce current within a plurality of coils. In at least one embodiment, the waveform patterns include a plurality of hyperbolic waveforms axially aligned around a horizontal center of the system.

Microfluidic devices are described that include a microfluidic channel, a first array of one or more magnets above the microfluidic channel, each magnet in the first array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the first array, and a second array of one or more magnets beneath the microfluidic channel, each magnet in the second array having a magnetic pole orientation opposite to a magnetic pole orientation of an adjacent magnet in the second array. The first array is aligned with respect to the second array such that magnetic fields emitted by the first array and second array generate a magnetic flux gradient profile extending through the channel. An absolute value of the profile includes a first maximum and a second maximum that bound a local minimum. The local minimum is located within the microfluidic channel or less than 5 mm away from a wall of the microfluidic channel. Methods of using the new devices are also described.

A sorting apparatus is provided for sorting selected magnetically attractable articles from non-selected magnetically attractable articles in a stream of articles. A sensor generates sensor signals representative of a property associated with a selected class of magnetically attractable articles. A separator device includes an array of magnets. A controller receives sensor signals from the sensor, identifies a location within the stream of articles of a selected magnetically attractable article, and selectively activates one or more magnets of the array of magnets and thereby magnetically attracts the selected magnetically attractable article from a first trajectory into a second trajectory while allowing non-selected magnetically attractable articles to continue along the first trajectory.
