Abstract: A method for enhancing the winter-spring quality of turfgrass by application of a composition containing a sand that has been colored with a dark colorant. The color is typically a dark green or black and can be prepared by mixing a latex paint with a white sand. The darkened sand absorbs radiant sunlight and raises the temperature of the turfgrass thus hastening growth and spring greening. The method is especially useful for golf course putting greens and a preferred application is to apply the composition in the fall prior to snow or ice accumulation. Such use on golf course putting greens will cause the turf to break dormancy and grow earlier than normal in the spring thus enhancing the quality and enjoyment of early spring playing.

Abstract: An actuator for aerosol spray cans utilizing a toe, as a pivot point, to engage the inside recess on the cup rim bead of the can (the bead which surrounds the spray nozzle) and a heel portion that extends against the valve stem mount. The body and handle of the actuator extend from the toe and heel upward and over the spray nozzle of the can with the handle being positioned approximately perpendicular to the direction of the spray exhaust of the can. Spray action is initiated by depressing the handle of the actuator with forefinger or thumb, causing the toe of the actuator to act as a pivot in the inside recess of the cup rim bead and the heel to slide against the valve stem mount. A protrusion on the body of the actuator depresses the aerosol spray nozzle creating a spray exhaust. The end of the actuator handle is formed to insert into the spray can cap and is used as a pry for removing the cap from the can.

Abstract: Process for producing novel mulching pellets from waste paper scrap by incorporating particulate water-insoluble, swellable, gel-forming polymer into the pellet-forming composition. The formed pellets swell and disintegrate after being spread and impregnated with water, to increase their area of ground-coverage, to release any included nutrients or seeds, and to deposit polymer particles having water-absorbing properties.

Abstract: A calibrating device for use with centrifugal, pendulum or other types of broadcast spreaders which distribute dry granular materials to be soil for agricultural purposes is described. The device provides containment of granular materials while the spreader operates without hindrance over a predetermined distance. The invention permits the rapid and efficient calibration of broadcast spreaders and thus ensures that optimal application rates of agricultural materials will be delivered with attendant cost savings and other operational advantages.
