Abstract: A mixer apparatus for use with a vessel centered about a longitudinal axis is disclosed. The mixer has a tubular blade which: defines a central head axis; has a first end and a second end spaced from the first end along the head axis; and tapers from the first end to the second end. The outer surface of the blade and the second end define an inside blade diameter “ID” and the outer surface of the blade and the first end define an outside blade diameter “OD”. The blade is positioned within and coaxial to the vessel. A scotch yoke, operatively connected to the blade by a shaft, effects reciprocating longitudinal movement of the blade through a stroke “S”, with a duration “T” for each stroke, wherein 175?0.36×OD2/ID2×S/T?250 when OD, ID and S are expressed in inches, and T is expressed in minutes.

Abstract: The present invention relates to an apparatus, which can be made portable, for presenting batch samples of flowable objects for image capturing, more particularly to an automated apparatus that allows for the image analysis of grain or seeds. Objects are deposited into the hopper of the apparatus and, in a continuous stream, are received from the metered bottom opening of the hopper onto a metering belt, the surface of which is textured so as to frictionally-engage the objects. Objects are thereafter deposited, in a high density monolayer, into discrete object presentation areas on an imaging conveyor. The mechanics of the apparatus are co-ordinated to allow for the simultaneous triggering of a radiation device and an image capturing means only at the instant when the object presentation area arrives at a particular location on the imaging conveyor. Image data is captured with respect to every discrete object within an object presentation area, and is analysed by a computer.

Abstract: A mixer apparatus for use with a vessel centered about a longitudinal axis is disclosed. The mixer has a tubular blade which: defines a central head axis; has a first end and a second end spaced from the first end along the head axis; and tapers from the first end to the second end. The inner surface of the blade and the second end define an inside blade diameter “ID” and the outer surface of the blade and the first end define an outer blade diameter “OD”. The blade is positioned within and coaxial to the vessel. A scotch yoke, operatively connected to the blade by a shaft, effects reciprocating longitudinal movement of the blade through a stroke “S”, with a duration “T” for each cycle, wherein 175≦0.36×OD2/ID2×S/T≦250 when OD, ID and S are expressed in inches, and T is expressed in minutes.

Abstract: A mixer apparatus for use with a vessel (102) centered about a longitudinal axis is disclosed. The mixer has a tubular blade (106) which: defines a central head axis (H-H); has a first end (120) and a second end spaced from the first end (122) along the head axis; and tapers from the first end to the second end. The inner surface of the blade and the second end define an inside blade diameter “ID” and the outer surface of the blade and the first end define an outer blade diameter “OD”. The blade is positioned within and coaxial to the vessel. A scotch yoke (144), operatively connected to the blade by a shaft, effects reciprocating longitudinal movement of the blade through a stroke “S”, with a duration “T” for each stroke, wherein 175≧0.36×OD2×S/T≦250 when OD, ID and S are expressed in inches, and T is expressed in seconds.

Abstract: A visual display apparatus for producing toroid rings of a first liquid within a second liquid is disclosed. The apparatus comprises a subtantially transparent viewing vessel for containing the second liquid. A variable volume chamber has an ejection orifice in fluid communication with the second liquid contained within the viewing vessel. An ejection means is also provided for varying the volume of the variable volume chamber, thereby to dispel an ejection slug of the first liquid from the ejection port, thereby producing a series of toroid rings which propagate through the viewing vessel. A control means is connected to the ejection means for controlling the operation of the ejection means. The operation of the control means may be such that it can be used to vary the volume and frequency of the ejection slugs emitted from the ejection orifice.
