Abstract: Propellant charges or grains having printed layers of two or more energetic materials are described along with methods for preparing and using them.

Abstract: An upwardly extending sectional candle is provided. The candle includes adjacent upper and lower wax sections stacked vertically relative to each other, each wax section having a thickness. The candle also includes a spacer formed from a non-flammable material. The spacer has a first surface, a second surface, and a thickness, wherein the first and second surfaces have a non-flat shape. The spacer contacts the upper wax section at the first surface and the lower wax section at the second surface. Each adjacent upper and lower wax section has a wick embedded in, and extending vertically through each wax section. The adjacent upper and lower wax sections are configured to be separated into individual wax sections at the spacer, thus exposing a like-new clean wax surface of the at least one of the upper and lower individual wax sections after the candle is separated.

Abstract: An application for a method of making a candle includes providing a candle core and adding a base layer of wax to the candle core. Next, an image area is cut out of the base layer large enough to contain an image and the base layer is peeled away from the candle core in the image area. An adhesion layer of wax is added to the candle core. An image is installed in the image area. A clear layer of wax is added to the candle core, also covering the image. An outer layer of wax is added to the candle core, also covering the image area then the image area is cut out of the outer layer and the outer layer is peeled away from the candle core in the image area.
