Abstract: A flight lug is provided for releasable attachment to a conveyor belt. The lug comprises a base and first and second side walls mounted to opposite edge surfaces of the base such that the base extends between and interconnects the side walls intermediate upper and lower ends of the side walls. Flanges extend inwardly from adjacent the lower ends of the side walls. Each flange defines a slot between the flange and the lower surface of the base for receiving an edge of the belt. The first side wall is pivotally attached to the base for movement relative to the base between a first position where the flange on the lower end of the first side wall is spaced a first distance from the flange on the lower end of the second side wall for allowing the belt to fit between the flanges, and a second position where the flanges on the side walls are spaced apart a second distance which is less than the width of the belt for capturing the belt in the slots between the side walls.

Abstract: Agents for lowering glucose levels in blood having the formula: ##STR1## wherein each R, independently, is hydrogen, C.sub.1-6 alkylcarbonyl or a group of the formula ##STR2## where R.sub.1 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 -alkoxy, halo or trifluoromethyl, andR.sub.2 is hydrogen, C.sub.1-3 alkyl, C.sub.1-3 alkoxy or halo, with the proviso that when one R is hydrogen, the other R is not hydrogen.
