Abstract:
The invention relates to a stirring device (1) that comprises a stirring tool which can be introduced into a mass or liquid that is to be stirred, a drive motor (4) that drives said stirring tool, a housing (5) enclosing said drive motor (4) and a fastening point (6) for securing said stirring device in a working position. The stirring device (1) has at least one sensor (11) for detecting imbalances which preferably is linked or connected to the open- and closed-loop control systems of the drive motor (4), and which can switch off said drive motor (4) or change the speed thereof in the event of undesired or dangerous oscillations or vibrations.
Abstract:
A mixing machine (10) includes a drive assembly (26) and control system (70) for making speed changes on the fly and for providing controlled acceleration and deceleration. A bowl receiving portion (20) may be movable between a lowered position and a raised position with a power bowl lift mechanism (54) provided to effect such movement. Advanced control features and special function modes may also be provided.
Abstract:
An article handling system and method for holding articles and moving selected articles individually from and/or to the article handling system. A plurality of vertically spaced article holding trays are mounted for independent rotation, each tray having a plurality of discrete article holding locations. A tray rotating mechanism is arranged to rotate a single selected tray, while a pick-and-place mechanism has an article gripper mounted for vertical and horizontal movement such that the gripper can reach any article holding location on any selected tray. A controller coordinates rotation of the selected tray and movement of the gripper such that the gripper can move to and from the selected article holding location. The handling system is especially useful as part of an automated system for processing multiple specimens of biological fluid in separate vials.
Abstract:
A filter assembly for separating and collecting a layer of particulate matter (e.g., cells) from a liquid containing the particulate matter (e.g., a biological fluid specimen). The filter assembly has a holder and contiguous inner and outer fluid pervious media. The outer fluid pervious medium is attached to the sidewall of the holder. The inner fluid pervious medium is of low fluidic impedance relative to the outer fluid pervious medium. The filter assembly is designed for use in a separation housing that defines two flow paths between inlet and outlet, one directly through the filter and the other around the periphery of the filter. The inlet portion of the housing has a central inlet in a radially sloped surface that faces the filter collection site. A movable suction head is adapted to cooperate with the housing and the filter assembly.
Abstract:
A blender for home or commercial use that is rugged enough to blend frozen beverages, simple to use and safe. The blender includes an upper housing with a front housing door that covers the moving blending machinery. The blender also includes a cupholder receiving area which allows the user to safely insert a frozen food or beverage cup inside a cupholder for blending. After the start button is pressed, the cup and cupholder will be lifted together for blending in a balanced, linear motion by an elevator assembly. Dual lead screws or a dual belt drive are preferably used in the elevator assembly to achieve this balanced, linear motion. As the cupholder is lifted upward, a cover will be pressed over the top opening of the inserted cup to prevent spillage during blending. The elevator assembly continues to lift the cupholder upward until the rotating cutter blades of a spindle assembly cut through successive layers of the frozen food or beverage. To facilitate cleaning, the spindle assembly is preferably removable from the blender through use of a quick release coupling mechanism.
Abstract:
An agitator (10) includes a stem (11) having a shaft coupler (12) at one end adapted to be attached to the rotatable shaft (25) of a food mixing machine. The other end of the stem (11) has a mixing blade (13) which can be in the shape of the bowl of a spoon. The stem (11) is shaped like an I-beam having side walls (20) spaced by a central wall (21). The side walls (20) have opposed notches (22) leaving a web (23) therebetween, and the central wall (21) is provided with an aperture (24) which is aligned with the web (23). Together the web (23) and the aperture (24) define a weakened area where the stem (11) will break upon a predetermined torque which is established based on the hardness of the food product (26) being mixed.
Abstract:
Method and apparatus for sorting and dispensing articles, one at a time, from the bottom of a stack of like articles. The articles are yieldably supported in at least one upright stack above an outlet, e.g. a resilient choke, sized to pass the articles if forced therethrough. Articles are dispensed by pressing downwardly on the stack with sufficient force and for sufficient duration to overcome the yieldable supporting force and move the lowest article through the outlet. Sensors may be provided for sensing when an article is dispensed, when the tube is empty, and the type of article in the holder. The method and apparatus are especially useful in a vial-based automated system for processing multiple specimens of biological fluid, wherein a filter assembly must be dispensed into a filtration chamber associated with each specimen vial.
Abstract:
Method and apparatus for mixing a specimen (e.g., a biological fluid specimen) in an upstanding container having an internal mixer with a cavity defined by an upstanding annular wall. The annular wall of the mixer is engaged by a movable holder, which is elevated along with the engaged mixer sufficiently to prevent contact of the mixer with the container during mixing. The mixer is then moved to mix the specimen. The holder, which may include an expanding collet that fits within the cavity of the mixer, preferably rotates the mixer to stir the specimen. When mixing is complete, the holder is disengaged from the mixer. A controller coordinates all actions of the holder.
