  • Patent number: 7938032
    Abstract: A dissolution test apparatus includes a vessel support member, weight sensors, a movable component, a media transport cannula, a pump, and an electronic controller. The vessel support member receives vessels. A weight sensor is located at each vessel site. Each weight sensor contacts a vessel and transmits a measurement signal indicative of the weight of the vessel and any contents therein. The movable component moves the media transport cannula toward a vessel site. The pump establishes media flow between the media transport cannula and the selected vessel. The controller communicates with the weight sensors and may also communicate with the pump. Based on the measurement signals received from the weight sensors, the electronic controller may calculate the volume of media in a given vessel. The electronic controller may also control media flows to or from the vessels by transmitting control signals to the pump assembly.

    Abstract: A Revolutionary Dialysis Container for safe dialysis of biological samples is described. A handle with wide top gives a non-slippery grip to lift and carry the container by a human hand. On its bottom, the buffer reservoir possesses a Sample Saver, which is nothing but a flat top plate attached to a vertical side wall. The reservoir holds dialysis buffer and bags containing biological samples. The Sample Saver encloses a bar magnet. The flat top plate and the vertical side wall of Sample Saver have several openings for the free flow of buffer during dialysis. However, these openings eliminate physical contact between dialysis bags and the highly spinning bar magnet. Also, the flat top plate, because of special distribution of openings, suppresses the formation of vortex in buffer during mixing. This preassembled unit also provides safety to long dialysis bags. One can dialyze fast and save time. It is simple to use and practically free of maintenance.

The agitator includes an agitating section having agitating pieces, which are capable of agitating clothes, or any other medium, and a driving mechanism for moving the agitating section. The driving mechanism moves the agitating section in a plane such that each agitating piece moves in a substantially identically shaped path.

  • Patent number: 5758966
    Abstract: An abrasion resistant bearing system for use in the agitation assembly of a mineral dissolution machine. The agitation assembly is part of the mixing tank where abrasive materials such as gypsum, nitrogen, potassium, sulphur and the like are kept in a mixed condition for ultimate discharge into an agricultural irrigation system. The vertical orientation of the agitation shafts allows for more consistent mixing at low speeds.

  • Patent number: 5700087
    Abstract: For specialized use to secure reliable standardized complete distribution or solution of aggregate mixed into a liquid diluent, a vessel having an interior hemispherical concave bottom having extending upwardly centrally from the concave bottom an arcuate conical member having upright concavely-shaped circumscribing sides. The vessel is taken in conjunction with a stably mounted mixing structure having a downwardly-extending shaft and mixing blades thereof. The shaft on a lower portion thereof supports balanced mixing blades extending radially outwardly from the mixing shaft. The mixing blades are positioned to be substantially spaced below a predetermined liquid level of liquid diluent containing a dissolvable or suspendable aggregate and to be substantially spaced above an upper end of the centrally upwardly arcuate conical member.

  • Patent number: 5578201
    Abstract: A reusable apparatus for multiphase, multistage countercurrent liquid separation is presented. The apparatus is particular useful in progressive multistage separation of target microorganisms from background organisms and materials with precise transfer, air exclusion, homogeneous mixing, isolation from the ambient atmosphere, in the absence of valves and at ow cost. The structure has at least one chamber in which a piston-like sliding bottom is sealingly moved or braked and includes internal structure for mixing, preferably a magnetic-stainless steel ball which can be reciprocated from the outside to mix the liquid contents. Motion of the bottom is limited by stops. A number of ways to actuate the apparatus are taught.

  • Patent number: 5568973
    Abstract: An antifoaming agent is deposited on a stirring or straw element to be placed in a beverage receptacle. The disposition of this material on the element speeds up the pouring process and is useful in high volume environments, such as airliners, convenience stores, and college bars. The preferred material for the antifoam coating is DOW CORNING.RTM. Antifoam FG-10, which is a ten percent active, food grade silicone emulsion.

  • Patent number: 5478148
    Abstract: A fluid tight container 11 defines a conical internal cavity 35, and has an upper feed pipe 12 and a lower outlet opening 14. A cylindrical stirrer 15 is wholly enclosed in the cavity, and is driven in a circular oscillating manner by an external eccentric mechanism coupled to an extension of the stirrer. This arrangement makes it possible to mix products of high viscosity and gas without excessive heating and leakage, by virtue of the exclusive use of static fluid-tightness.

  • Patent number: 5468616
    Abstract: A method and apparatus for accelerating at least one definitive biological reaction including increasing the accuracy of determinations made therefrom. The reaction involves selected viable biological cells which are prepared in a small sample volume and rapidly mixed with microspheres having antibody specific at least to specific ones of the cells bound thereto. The microspheres can be magnetic and the bound cells can be magnetically removed to analyze the remaining blood cell populations. The microspheres can be introduced sequentially or simultaneously.

  • Patent number: 5464752
    Abstract: A method and apparatus for automatically and rapidly, retrieving, counting and/or analyzing at least one selected white blood cell population and/or subset thereof of a whole blood sample or portion thereof. A volume of a biological sample containing the white blood cells is prepared and at least one reactant specific or preferential at least to some selected biological cells is introduced thereto and rapidly mixed for a short period of time. The opacity and/or volume parameter of the cells can be modified and the mixture is then counted and analyzed in one or more steps to obtain the desired white blood cell population analysis.The biological sample can be a whole blood sample and the reactant can include or be a lyse or a monoclonal antibody bound to microspheres, which will bind to specific ones of the cells or a combination of lyse and microspheres with antibody bound thereto.
