Abstract: Compositions and methods of making compositions containing nopal cactus isolates derived from the juice and/or soluble solid fractions of nopal pads. In another aspect, the invention relates to compositions for making coffee, coffee compositions and methods of making such compositions, which contain nopal cactus isolates.

Abstract: An electronic marker device affixes a fishing rod to a fishing reel. The device includes a marker housing having a base and a cover to enclose the moveable socket of a fishing rod thereby preventing removal of the fishing reel from the fishing rod. The marker housing also supports an electronic marker so as to deter unauthorized removal of the rod and reel combination. The marker may be preferably an electronic article surveillance (EAS) marker.

Abstract: A multifocal diffractive lens includes at least two annular zone lenses. Provided between adjacent annular zone lenses is an optical step. Each annular zone lens exhibits a refractive power profile D.sub.g,i (r) wherein i is any i-th annular zone lens and r is the distance between an axis of the diffractive lens and a point on a back surface of the lens. The lens is further characterized in that an average power of zones i,j . . . are given by D.sub.av,i, D.sub.avj . . . respectively, and optical path lengths of light rays extending from an object point to a conjugated image point are different by the optical step for light rays transmitting through adjacent annular zone lenses. The annular zone lenses are shaped and positioned such that all of the average refractive powers D.sub.av,i, D.sub.avj . . . are substantially equal to a single value, D.sub.av.
