Abstract: A viscometer adapted to determine a temperature at which a liquid test sample has a predetermined viscosity. A method of operating a viscometer comprising the steps of: drying the air contained in the capillary tube; advancing the liquid test sample from the sample reservoir to the capillary tube; changing the temperature of the liquid test sample to a first sub-zero degrees Celsius temperature, and determining a first viscosity of the liquid test sample at the first sub-zero degrees Celsius temperature. Use of a capillary tube for determining a temperature at which a liquid test sample has a predetermined viscosity.

Abstract: A chaff spreader for attachment to a farm combine. The spreader rotates to spread chaff discharged from the combine and is readily removable and adjustable to the discharge opening in the combine. Novel safety rings are provided on the rotating spreader to protect operators or others who might come into contact with the rotor.

Abstract: A reusable planter box with four side panels can be assembled and disassembled with ease, and are still durable enough to accommodate large plants and trees. The side panels of the planter box contain three inserting means on one edge and three receiving means on the second edge that can be brought together to form the connection between the two adjacent panels. These connections are secured by securing means located adjacent to the receiving means and hold the inserting means in place. The connection can be further secured by placing a cotter pin in a horizontal bore through the inserting means preventing the inserting means and receiving means from detaching. The lower part of the planter forms a ledge on which a disposable bottom shelf can be placed. Footings on each panel raise the shelf above the ground, which slows deterioration of the shelf and prevents roots from growing into the ground.
