<p>1394847 Pipe couplings LUCIFER SA 8 Dec 1972 [17 Dec 1971] 56645/72 Heading F2G In a fluid control system, e.g. for the pneumatic operation of a double acting ram, valve blocks 4, 5 are so interconnected, by a pair of clips 14, that interlocking formations prevent relative movement of the blocks in two mutually perpendicular directions, in the plane of the mating surfaces 20. Thus, relative movement in the plane of Fig. 3 is prevented by the engagement of a cross-piece 17 in a corresponding recess 29, in the margins of the blocks. The perpendicular movement is prevented by the edges 37 of extensions 15 abutting the end walls of recesses 20b. Alternative forms of clip are described.</p> |
