Abstract: Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective soil treatment form prior to its application. Calcium cyanamide transformation structures have both fertilizing and pesticidal qualities; however, it is difficult to obtain uniform, efficient effectiveness from dry calcium cyanamide's liquid transformation structures. In the process of this invention, dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil.

Abstract: A garage door-opener security system which automatically positively blocks any unauthorized opening of a sectional garage door that travels, guided by rollers, in a pair of flanking metal guide tracks. The security system is interconnected with a standard, automatic, garage door-opening mechanism that includes an electric drive motor. When the door reaches its fully closed position, a locking device, mounted adjacent one of the flanking tracks, physically inserts a locking pin into the trackway in which the rollers move, which pin is located a few inches above the roller next below. The locking pin is closely confined by a surrounding aperture which prevents its upward deflection or twisting, thus making it impossible for the roller to move therepast in the trackway and positively preventing the raising of the door more than a few inches.
