  • Patent number: 10092888
    Abstract: A linear reciprocating actuator for mixing, agitating, separation, continuous sampling and/or harvesting or filtration, gas mixing, and various other applications. The actuator may have a housing closed on one end, and attached to a vessel in a hermetically-sealed manner such that it is part of the fluidic envelope of the vessel. An agitation device may be attached to a shaft which is partially surrounded by the housing, or the agitation device may surround the housing where the housing protrudes into the vessel. The actuator enables agitation of the contents of a hermetically-sealed vessel without mechanical coupling from outside the fluidic envelope of the process. The agitation device is solely acted upon by a magnetic field, is contained entirely within the fluidic envelope of the process, and is not attached to the vessel in any way. The magnetic flux which drives the agitation device passes through the housing.

  • Patent number: 9504973
    Abstract: Particulate matter is dispersed in a fluid material. A sample including a first material in a fluid state and second material comprising particulate matter are placed into a chamber. The second material is spatially dispersed in the first material utilizing EMAT force. The dispersion process continues until spatial distribution of the second material enables the sample to meet a specified criterion. The chamber and/or the sample is electrically conductive. The EMAT force is generated by placing the chamber coaxially within an induction coil driven by an applied alternating current and placing the chamber and induction coil coaxially within a high field magnetic. The EMAT force is coupled to the sample without physical contact to the sample or to the chamber, by another physical object. Batch and continuous processing are utilized. The chamber may be folded within the bore of the magnet. Acoustic force frequency and/or temperature may be controlled.

  • Patent number: 8807824
    Abstract: An apparatus for frothing a liquid food product is disclosed. It comprises a drive unit (1) and a frothing unit (3). The frothing unit (3) comprises a guide rod (30), which is configured along at least one section as a threaded rod (31). A frothing element (40) is in threaded engagement with the guide rod (30) and can thus be moved along a helical path on the guide rod (30). At least one dog (36, 36?) is driven by the drive unit (1) in a circular motion about the longitudinal axis of the guide rod (30) and in the process entrains the frothing element (40) such that said element is driven to perform a helical motion on the guide rod (30). In this way, the frothing element can perform an up and down motion superimposed on the rotational motion thereof along the longitudinal direction.

  • Patent number: 8741631
    Abstract: A device for biological purposes such as cell culturing, enzymatic reactions or filtering of fluid has a body with first and second surfaces. The body is delimited by a rim and an aperture in the center of the body. The aperture is covered at the first and second surface by first and second plates. The first and/or second plate has an inlet orifice allowing liquid medium into the aperture. Rotating means are arranged in the aperture between the first and second plate. At least one recessed portion is a cavity in the rim of the body having a first outlet orifice allowing the liquid medium to flow out of the body. At least one outlet channel connects the circular aperture with the recessed portion. Liquid is pumped into the aperture of the device and pumped through at least one outlet channel.

  • Publication number: 20140133265
    Abstract: Provided are liquid agitating systems having magnetically actuated agitating members that do not come in contact with internal surfaces of liquid holding vessels. As such, some mechanically weak materials, such as polytetrafluoroethylene and perfluoroalkoxy polymer, may be used for internal surfaces of these vessels. An agitating member may be held by a supporting member that allows the agitating member to move within a vessel without touching its bottom. The supporting member effectively controls the distance between the agitating member and some supporting point. An external magnet provided under the vessel may be used for magnetic actuation. The agitating member includes an internal magnet that is magnetically coupled to the external magnet and that follows the path of the external magnet thereby moving the agitating member and agitating the liquid. In some embodiments, multiple external magnets may be used to position one or more agitating member.

  • Patent number: 8681496
    Abstract: Cooling apparatuses, electronic device assemblies, and cooling assemblies having a magnetic shape memory member are disclosed. In one embodiment, a cooling apparatus includes a first compliant member, a magnetic shape memory member, a magnetic field generating device, a second compliant member and a fan member. A first end of the magnetic shape memory member is coupled to the first compliant member. The magnetic field generating device is positioned proximate the magnetic shape memory member, and generates a magnetic field toward the magnetic shape memory member to cause the magnetic shape memory member to expand along a linear translation axis. Expansion of the magnetic shape memory member causes an actuated portion of the second compliant member to translate about an axis. The fan member is coupled to the actuated portion of the compliant member such that translation of the actuated portion translates the fan member.
