The jam nut defines an annular shoulder which is engageable by the wrench annular surface and has internal threads which are mated to the external threads of the insert, for bringing the insert into fluid-tight engagement with the drum opening. The crank, removably engageable with the shaft at the insert-carried end portion of the shaft, is used by an operator to manually rotate the propeller in the drum.

  • Patent number: 5411331
    Abstract: A device for promoting gravity flow of zirconium tetrachloride and other non-free-flowing solids has a rotatable shaft. At least two flexible lengths have first ends attached to and axially spaced on the shaft and also distal second ends. A collar is slidably mounted on the shaft between the spaced first ends of the flexible lengths for slidable axial and circumferential movement on the shaft. At least one sweep arm has a first end pivotally attached to the collar and a second distal end attached to the second distal ends of the flexible lengths. The collar slides relative to the shaft as the sweep arm encounters resistance from bridged solids. The relative movement of the collar and shaft causes the flexible lengths to wrap around the shaft and the arms to collapse toward the shaft. A device with collapsible arms will have a minimal torque requirement. When the solids dislodge from the collapsed sweep arms, the arms extend to sweep outwardly to a maximum extent.

  • Patent number: 5326167
    Abstract: A stirring system for stirring contents in a laboratory flask having a round or spherical bottom and a reduced neck includes a stirrer shaft manufactured with a ring at the lower end thereof which permits attachment of a blade with a nut and bolt made of TEFLON material. The nut and bolt prevents the stirrer blade from flipping over during assembly and allows for a controlled tightening force to be applied to ensure that the blade remains in proper stirring position during use. The nut and bolt design permits use of the shaft with any stirrer blade having a keyhole cutout or circular opening. A method of stirring contents in a laboratory flask by attachment of the stirrer blade to the stirrer shaft with a nut and bolt is also disclosed.

  • Patent number: 5208050
    Abstract: A frozen yoghurt or ice cream dispensing system is presented. This system costs a small fraction that of the state of the art dispensing system, yet it is more versatile and puts out a better product, than the state of the art systems. A pre-formed "hard" frozen single serving of the base confection and fresh flavoring additives are loaded into an extrusion cup. At the actuation of a hand crank, or a power drive switch, a rotating cutter/sweeper on a retractable shaft, penetrates the confection charge and chops, softens, and mixes it. After this cutter engages the bottom of said cup, a piston traverses the loading cup bore, and the charge is extruded through a multi-aperture orifice, at the bottom of the extrusion cup. Shearing and additional mixing occurs, during the interaction of the rotating cutter and the multi-aperture orifice. An automatic rinse cycle is also built into the device, to eliminate flavor mixing between various batches of confections, and to save labor.

  • Patent number: 5192131
    Abstract: An elongate inner tubular sleeve is slidably mounted within an outer tubular sleeve, with the inner sleeve mounting a plurality of actuator links to permit axial displacement of the inner sleeve relative to the outer sleeve, wherein the inner sleeve pivotally mounts an annular array of paddle blades at a lower distal end of the inner sleeve that are positioned exteriorly of the outer sleeve, whereupon axial displacement of the inner sleeve relative to the outer sleeve effects radial displacement of each paddle blade relative to the outer sleeve to permit a stirring thereof, with the actuator links projecting exteriorly to provide for a handle structure permitting ease of rotation of the stirring device within a container.

  • Patent number: 5183336
    Abstract: For use with large size containers having narrow entrance openings, the stirrer blade is mounted on a support rod for pivotal movement from an angled position which permits insertion into the narrow entrance opening to a perpendicular position suitable for stirring. The blade is carried on a slotted tube which has a recess into which a plunger connected to the end of the rod is movably received. The plunger contacts the upper edge of the blade. Once the blade is situated in the container, the rod is moved relative to the tube, causing the plunger to pivot the blade to the stirring position.

  • Patent number: 4981367
    Abstract: Portable mixing apparatus is disclosed which is specially adapted for use in containers such as standard 55 gallon drums and the like which have an opening or "bung" near an edge of the container. A mounting plate is provided which has a threaded end secured in the bung, and a flange secured at a selected angle to the threaded end. A collapsible propeller and mixing shaft pass into the container through the threaded end and a motor operatively connected to the mixing shaft is secured to the mounting plate around the container opening by spaced bolts which pass through and lock into keyhole slots in the mounting plate. The motor, mixing shaft and propeller are secured at an angle so that the propeller is in a selected quadrant near the axis, and preferably also the bottom, of the container. The apparatus can easily be installed and removed without twisting or tangling the power cord.

  • Patent number: 4872764
    Abstract: A beverage processing apparatus consisting of an outer housing having an upper portion and a lower portion which together form a closed processing vessel for containing a beverage mixture, the upper portion containing a driving motor that drives the shaft which has on it one or more processing blades, the invention being characterized by the fact that the blade or blades are pivotally attached to the shaft so as to be capable of folding up against the shaft as it is introduced into a mixture to be processed containing, for example, ice cubes, and thereafter under the influence of centrifugal force to take up a position substantially at right angles to the shaft to effect efficient processing. It is preferred that the or each blade has a surface upwardly inclined in relation to a plane at right angles to the axis of the shaft to promote folding of the blade in the event of it striking an obstacle during processing.
