    摘要： A cap shoe for connecting a mine prop to a head tree or cap in the form of a U-shaped girder whose U shanks have corrugations extending the full width thereof is engageable by complementary formations on the flanges of the cap or head tree which is received in the shoe. The latter is welded to the mine prop.

    摘要： Polyether-ketones containing the structural unit ##STR1## have a completely linear structure, and are heat-stable and free from crosslinking reactions during processing at from 390.degree. to 420.degree. C.They are prepared by Friedel-Crafts acylation of terephthaloyl chloride or terephthaloyl fluoride with diphenyl ether in hydrogen fluoride as a solvent and with boron trifluoride as a catalyst, the polycondensation reaction being carried out by a method in which the reaction mixture is a homogeneous solution.

    摘要： A coupling particularly for use with colliery roadway supports. The coupling between an upright channel section or `I` beam and a crown beam of a similar cross-section is formed from two plates. At least a first of the plates is formed so as to lie between opposed flanges of the upright and opposed other of the two plates. The first plate extends beyond the head of the upright to a lip portion hooking all its width over the lower flange of the crown beam with preferably a bolt passing through the lip portion, the crown beam and opposed other plate. The clamping of the two plates together by the bolt or bolts securing the upright to the crown beam achieves a high resistance to lateral loading on the assembled beams to form a support.
