  • Patent number: 10105664
    Abstract: Agitation mechanisms for homogenization devices for processing sample materials in tubes that are secured by tube holders to the agitation mechanisms. Each agitation mechanism includes a first rotary member having a first fixed rotational axis, a second rotary member having a second fixed rotational axis, and a connecting member that extends between them, is rotationally mounted to them at third and fourth non-fixed rotational axes, and to which the tube holder is mounted, with the first and third rotational axes defining a first offset, and with the second and fourth rotational axes defining a second offset. When the first rotary member is driven through rotation, the sample in the tube in the tube holder on the connecting member is driven through a nonlinearly reciprocating motion profile to produce a grinding shear action to better homogenize the samples. Other disclosed embodiments produce linearly reciprocating motion profiles.

  • Patent number: 10005050
    Abstract: The invention relates to a method for using a SWING-type mixing device (1) and to a SWING-type mixing device (1), in which a main turning axle (2) of the mixing device is turned back and forth, that is in turns to a first direction all the way to a first turning point (FT) and to a second direction all the way to a second turning point (ST). According to the invention, power transmission to the main turning axle (2) can be produced by terminating power transmission to one direction slightly before the turning point, by letting mass inertia of the apparatus handle the turning of the direction of movement at the turning point and by starting power transmission to the opposite direction of the first slightly after the turning point.

  • Patent number: 7810989
    Abstract: A cocktail shaker uses a motor to cause a container to be shaken. The shaker includes a following member coupled to a following device that is engaged in a directional mechanism, such as a slot or rod. The directional mechanism defines the path and angle of the motion imparted to the container. The throw is defined by the mechanism that transforms rotational motion of a motor to a shaking motion of the container. A mechanism for transforming rotational motion to a shaking motion may include a rotational member and an attachment member pivotally coupled to the rotational member on one end and coupled to the device holding the container on the other end. A combination of throw, path, and motor speed are capable of providing a mechanism for shaking the container that is similar to shaking the container by hand. For example, the motor speed and duration of shaking may be continuously variable or discretely selectable, which may be selected by the user.

  • Patent number: 7645065
    Abstract: An experimental mixing device may comprise a driving source, an eccentric member, a control member and a mixing member. The control member may be selective installed in the experimental mixing device and be configured to adjust the mixing member, thereby providing various operational motions of the mixing member, for example an orbital motion, a see-saw motion, a 3-D twist motion, or a crank motion. The use of the control member may eliminate the need of separating the mixing member from the experimental mixing device. Thereby, the experimental mixing device may have adjustable patterns and quantity of the mixing motion and lead to easy usage and manufacture.

The support allows for vertically supporting up to two paint mixers, each supported on a separate horizontal plate. The tray is movable between a horizontal operating position wherein the paint container may be placed on the tray and the lid pounded down against the container, and a vertical storage position wherein the tray is pivoted up out of the way, where it may rest against a paint mixer, retained there by magnets. In the absence of an upper paint mixer, the tray may be further pivoted to rest against the upper plate resulting in a shipping position for the tray and stand. The tray may have a pair of arms in contact with the stand to support the tray in the operating position.

    Abstract: A paint shaker and motor therefor. A yoke has at a first end a clamp for clamping a paint can and at a second end, is pivotally connected to a linkage assembly that converts the linear motion of a reciprocating linear motor to an arcing motion of the yoke. The motor includes a cylinder and a piston that is spring biased toward an inlet end of the cylinder. Compressed air enters the inlet end and a passageway through the piston for conducting the compressed air to a valve having a displaceable stopper, wherein the compressed air seats the stopper in the valve and thereby closes the valve, so that air pressure moves the piston toward an outlet end of the cylinder. The outlet end of the cylinder includes a projection against which the piston drives the stopper so as to unseat the stopper in the valve and thereby open the valve, permitting the spring bias to return the piston toward the inlet end of the cylinder.

  • Patent number: 6059446
    Abstract: The present invention reveals an apparatus for mechanically finger vortexing microcentrifuge tubes. The apparatus is made of a box; a tube-holding rack having a frame, where the top of a microcentrifuge tube is held in a pivotal position; a base plate having a plurality of upright ribs, where the ribs cause a pull-and-release action either directly or indirectly on a microcentrifuge tube; a wheel, where the wheel is connected to an armature and where the armature is connected to the base plate; and a motor with a shaft, where the shaft is connected to the wheel. In the operation of the apparatus, the motor and the shaft impart a circular motion to the wheel and the armature transposes the circular motion of the motor-wheel to a reciprocating motion on the base plate. The reciprocating motion of the base plate causes the ribs to mix the contents of the microcentrifuge tubes.

    Abstract: A bath shaker (10) is provided for agitating liquid baths. The bath shaker (10) incorporates a "flexible parallelogram" mode of movement wherein a bath shelf (20) is attached to and supported by two, parallel opposing flexible arms (112). Present on each flexible arm (112) is a first attachment portion (124) sandwichedly held by an upright extension (120) and a first hold plate (110), the arrangement causing the first attachment portion (124) to serve as a flexible hinge. A drive mechanism (16) produces a reciprocating action of the bath shelf (20) through the use of an eccentric (80) and a pivoting lever (46) attached to both the eccentric (80) and the bath shelf (20). The flexible parallelogram arrangement defines the reciprocating motion to be substantially rectilinear and makes for an entirely noiseless mode of travel, while producing an extremely smooth transition between reciprocations.

  • Patent number: 5277493
    Abstract: An apparatus for melting samples in crucibles above burners while moving the crucibles to mix the contents. The crucibles are supported by movable shafts on a movable subframe. The shafts can oscillate in a horizontal plane to mix the contents of the crucible. The subframe can also oscillate vertically to mix the contents of the crucible. The crucible mixing pattern is the sum of the horizontal and the vertical motion applied to the crucible. The crucible can be moved back away from the burner to add additional material to the crucible. The crucible can be moved forward, away from the burner, to pour the melted sample into either a heated casting dish or a container containing a solution. Nothing is added to or poured from the crucible while over the burners.
