Abstract

1,236,417. Inflatable mine roof supports. MICHELIN & CIE (COMPAGNIE GENERALE DES ETABS. MICHELIN). 22 July, 1968 [20 July, 1967], No. 34939/68. Heading E1E. [Also in Divisions A4 and F2] An inflatable mine-roof support cushion when force from load has the side elevation shown and in plan has the shape of an elongated hexagon, see Fig. 1A (not shown). The upper and lower walls 11, 12 have different degrees of elasticity which is effected by using reinforcing cords of different material or different degrees of twist or by using extra cords for details of which including materials employed and disposition in rubber matrix, the Specification and remaining drawings (not shown), should be referred to.
