A spacer profile for a spacer profile frame mountable in the edge area of an insulating window unit for forming an intervening space between window panes, has a profile body made of synthetic material and comprises one or more chambers for accommodating hygroscopic material. A hoist lowers and raises the heating element into and out of the drum via vertical rods that are not heated. A countercurrent flow of inert fluid medium is sufficient for spheridization of the pre-prills into spherical pre-prills. The device may send an encrypted version of the random session key to the smart card reader. The present invention particularly relates to the soybean variety S07-02KG294306 and its progeny, and methods of making S07-02KG294306 and hybrid from S07-02KG294306.
