Abstract: A device for delivering ink to a substrate including a body member, an ink distribution chamber, a plurality of ink delivery nozzles, a plurality of ink passages formed in a side body member for delivering the ink from the ink distribution chamber to the ink delivery nozzles, the ink passages being formed, at least partially, as grooves in said side of the body member, and a filter element for filtering the ink entering the ink passages, said filter element being disposed on said side of the body member covering the grooves.

Abstract: A grid ceiling comprising a set of first parallel channel section elongate members and a set of second parallel channel section elongate members, the first members being so arranged transverse to the second members as to form a grid with polygonal spaces therein. Each channel shaped member includes a lower portion and two spaced side flanges extending upwardly therefrom. At least one integral hook is formed at each of the ends of the second members and co-operating first openings are formed in at least one side flange of the first members at first position situated at regular, spaced intervals therealong, so that the hooks of the second members can be engaged in said first openings to form said grid ceiling. A series of one or more second openings are formed in at least one side flange of the second member at second position situated at regular, spaced intervals therealong.

Abstract: A grid ceiling comprising a supporting grid (10,20) with rectangular openings therein, grid panels (30) mounted within said openings. The grid panels may be in the form of grid units including perpendicular hollow interior primary and secondary panels (40,50). The grid panels (30) are secured in place by longitudinally movable clips (60) which engage the carriers, e.g. in apertures or recesses (24). Each clip is slidable longitudinally from a forward position in which can occur and a retracted position in which the tongue is sufficiently within its associated panel to enable the grid panel to be removed.

Abstract: A clip for mounting a wall or ceiling panel structure having a plurality of panels in which the panels have inturned rims on their longitudinal edges and preferably beads on the rims. The clip has a body having downwardly extending first members preferably adjacent one edge and a downwardly extending fourth member preferably adjacent an opposite edge.A second downwardly extending member having lateral lugs is adjacent and spaced from the first member by an amount to accommodate two rims. A pair of third downwardly extending members is shaped to enable two panels to be spaced from one another and is also provided with a lug so that the clip may alternatively be used for mounting a panel adjacent a wall surface.
