Abstract: Described is a method of making a densified fiber batt that includes the steps of: a) providing a fiber batt with a first plurality of fibers having a first melting point and a second plurality of fibers having a second melting point different from the first melting point; and b) subjecting the fiber batt to heat and pressure in a static press, thereby forming a densified fiber batt having a first surface and an opposed second surface.

Abstract: Compounds of the general formula (I) ##STR1## (wherein R is H, alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl or CHO; and R.sup.1 and R.sup.2 each represents H, fluorine or chlorine);and their salts have selective .alpha..sub.2 -adrenoreceptor antagonist action.The compounds may be prepared by amination of compounds of the general formula (II): ##STR2## (wherein X is a leaving group).

Abstract: Compounds of the general formula: ##STR1## wherein the groups CHR.sup.1 NR.sup.2 R.sup.3 and CHR.sup.4 NR.sup.5 R.sup.6 may be the same or different and where the group CHR.sup.4 NR.sup.5 R.sup.6 is in either the 1 or the 3 position and R.sup.1 and R.sup.4 independently represent a hydrogen atom or an aryl group;R.sup.2, r.sup.3, r.sup.5 and R.sup.6 which may be the same or different are each a hydrogen atom or an alkyl group or an aryl group both of which may in turn be substituted by one or more hydroxy, alkoxy, acyloxy, dialkylamino or aryl groups or the groups --NR.sup.2 R.sup.3 and/or NR.sup.5 R.sup.6 represent a heterocyclic ring containing one or more hetero atoms and which ring may optionally be substituted by an alkyl, aryl or aralkyl group and in which either aromatic ring of the naphthalene nucleus may be further substituted; with the proviso that when R.sup.1, R.sup.4, R.sup.2 and R.sup.5 are hydrogen, then R.sup.3 and R.sup.
