The present invention is a cooling device for removing heat from an integrated circuit. The trap comprises two planar elements of substantially the same size, each with flat outer surface and an inner surface provided with a plurality of recessed areas. If desired, the hydroxybenzoate salts can be converted to either the free base or to another pharmaceutically acceptable salt form. The group of code-sets may form a tree, whereby the main-function and its code form root of the tree, whereby a sub-function forms a branch of the tree and a code or cedes defining this sub-function form a leaf or leaves of the branch. The bulged portions are preferably created by a coining process and facilitate binding mechanically the band to the buckle.
