Abstract:
A fluid mixing system that can be used as a bioreactor or fermentor can include a stand and a support housing pivotably mounted to the stand. The support housing bounds a chamber into which a container assembly is removably disposed. The container assembly includes a flexible bag bounding a compartment adapted to hold a fluid and a mixing element disposed within the compartment. The support housing can be tilted relative to the stand for ease in insertion of the container assembly. The support housing can also be repeatedly rocked relative to the stand form mixing fluid within the container assembly.
Abstract:
A variable height blender system is disclosed that includes an industrial blender carried by a first lift and a second lift for moving the blender up and down into any of various vertical positions. The variable height blender system includes drive controls for independently controlling movement of the first and second lifts, and a synchronizer in communication with at least one of the first and second drive controls for synchronizing the movement of the first and second lifts to maintain the batch blender substantially level. The synchronizer includes a level sensor that senses a tilt of the batch blender with respect to a local gravity vector and sends level reading signals to the synchronizer for use in independently adjusting the speeds of the first and/or second lift.
Abstract:
A mixer attachment for use with a skid steer. In one embodiment, the mixer attachment includes a mixing tub with a circumferential wall extending between a floor and a rim to define an interior compartment for holding a quantity of material. An auger may be provided that mixes the materials and is driven by a hydraulic drive unit. In some embodiments, one or more material retarders extend into the interior compartment to impede movement of the material within the interior compartment. A discharge chute allows discharge of material from the interior compartment. The mixing tub is movable between a scooping position and a mixing position.
Abstract:
A viscous fluid dispensing system and method of dispensing which includes a container mounted on a vibrating support. The container is normally the container from a blender in which a smoothie has been prepared. A motor drives an unbalanced weight which vibrates the container support. This fluidizes the viscous fluid in the container. The container, and the container support are pivoted. The vibration generating means continues to operate while the container is pivoted in order to provide for the uniform dispensing of the viscous fluid from the container.
Abstract:
A mixer system including a bowl for receiving a material to be mixed, a mixer body having a rotatable output component, and a hinge. The bowl is pivotable about the hinge relative to the mixer body such the bowl can be pivoted between a loading/unloading position and a closed position relative the mixer body. The mixer system further includes a locking mechanism located at least partially on one of the bowl or the mixer body, the locking mechanism being normally biased into a locking position. At least a portion the bowl or the mixer body interacts with the locking mechanism to move the locking mechanism toward the release position to allow the bowl to move to the closed position, the locking mechanism being movable back toward the locking position when the bowl is in the closed position to retain the bowl in the closed position.
Abstract:
The present invention discloses a generic method for producing void and gas occlusion free materials, as well as apparatuses for batch and continuous production of same. This generic method can be utilized in the production of a wide variety of polymeric compounds and composites and specifically encompasses the two ends of the polymeric composite spectrum, that is, polymer concretes on the one hand, and fiber-reinforced polymer composites on the other. The composite materials of the present invention are characterized by visual count as being void and gas occlusion free to the level of 1 micron at 1250.times. magnification. Concomitantly, the invention produces useful polymer concrete materials which exhibit substantially improved integrity for easy machining at high speeds, and high dielectric and mechanical strength, as compared with composite materials produced by conventional methods. Thus, one particularly well-suited application for the materials of the present invention is the class of high voltage electrical insulating materials and insulators where the presence of voids, or gas occlusion flaws, may have deleterious effects, leading to their early failure.
Abstract:
A domestic blender having a blade carried on a shaft, with the shaft being supported for rotation within a sleeve shape bearing is provided with a seal to prevent passage of liquid into an area between the blade shaft and the bearing. The seal is an annular member having a central opening sized to snugly fit around the blade shaft and with a perpendicularly extending flange having an inner diameter size to snugly fit around an outer circumferential surface of the bearing. Preferably the seal rotates with the shaft and slides along the bearing which may be accomplished by providing the shaft with a non-circular cross section and the seal with a complementarily shaped opening. Preferably the seal is formed of a lubricated plastic material to reduce friction and wear.
Abstract:
A kneader includes a vessel having an upper cover, at least one mixing blade provided in the vessel for mixing or kneading a powder material supplied in the vessel, sealing means for sealing between the vessel and ends of a shaft of the mixing blade extending through the vessel, bearings for supporting the shaft of the mixing blade on both the sides, blade driving means provided at one end of the shaft of the mixing blade. Each of the sealing means is provided on a side of the vessel with at least one air purge opening through which air is caused to flow toward the shaft of the mixing blade or into an interior of the vessel to form the sealing means as an air sealing construction, thereby completely preventing the powder material to be mixed from leaking through clearances between the vessel and the shaft by jetting air from the air sealing construction into the vessel.
Abstract:
A heated, variable tilt, rotating container or pot for making possible automatic, continuous mixing or tumbling, with or without simultaneous heating, of a plurality of foods or substances. The device consists of an outer non-rotating shell pivoting on a fixed base. Inside the shell is a pot rotated by a motor attached to the bottom of the shell. A cover is secured over the pot to prevent the contents from spilling out. The shell and its pot are tiltable as a unit to any angular position from vertical to horizontal. Compartments, dividers, ridges, projections or other shapes are inside the rotating pot or on the pot wall and/or bottom, to separate, move, mix and tumble the contents when the tilt angle of the pot is other than at the vertical position. The shell contains a suitable heating system for raising the temperature of the pot. The device is provided with an automatic temperature control, motor speed control and automatic time cycle and function indicators.
