Abstract: Immediate release formulation of a triple combination of active pharmaceutical ingredients useful in the treatment of polycystic ovarysyndrome It relates to an immediate release formulation for oral administration, comprising; a) a combination of three active pharmaceutical ingredients which are spironolactone; pioglitazone or a salt thereof; and metformin or a salt thereof; and b) solid polyethylene glycol having an average molecular weight from 3350 to 8000 g/mol; wherein: each of the active pharmaceutical ingredients are present in a therapeutically effective amount; and the polyethylene glycol is present in an amount such that decreases the dissolution profiles in vitro of each one of the active pharmaceutical ingredients without modifying the disintegration time of the formulation compared with the dissolution profiles of each one of the active pharmaceutical ingredients of a formulation having the same composition but without the solid polyethylene glycol, as well as, to its preparation process.

Abstract: Flame arrestor to cover aircraft engines made up of one ventilation wire grid (6), one upper metallic plate (9) where wire grid sits (6) on the edges of a circular hole (10) and a wall (25) which is located next to a chamfer (26) placed at the edge of a central hole (5) existing in the platform (3). On the lower side of the thin composite wall (25) there is a flange cylinder formed by a disc (15) a cylindrical ring (14) coinciding in height with the chamfer (26), creating an interior cavity (27) where gases are conducted and accumulated. All these elements are joined together by some bolts (22) that go through them and finish with a lower metallic plate (12) and an octagonal shaped part (19) separated by a specific distance established by the appropriate elements like bushing or spacer.

Abstract: Flame arrestor to cover aircraft engines made up of one ventilation wire mesh (6), one upper metallic plate (9) where wire mesh sits (6) on the edges of a circular hole (10) and a wall (25) which is located next to a chamfer (26) placed at the edge of a central hole (5) existing in the platform (3). On the lower side of the thin composite wall (25) there is a ring (16) with outer flange whose width coincides with that of the wall, and another flanged ring (14) coinciding in height with the chamfer (26), creating an interior cavity (27) where gases are conducted and accumulated. All these elements are joined together by some bolts (22) that go through them and finish with a lower metallic plate (12) and an octagonal shaped part (19) separated by a specific distance established by the appropriate elements.
