Abstract: A belt conveyor in which the belt travels around a lateral curve or curves and comprises load-supporting belt sections (2) pivoted between transverse rods (1), has guide blocks (4) at the ends of the transverse rods (1) with bearing parts (20) which co-operate substantially without friction with runners (5) at the or each curve to guide the belt in its travel with reduced wear and tension. Preferably the bearing parts (20) and runners (5) are made of self-lubricating material. In one form the bearing parts are horizontally facing channels (20) in the blocks (4) engaged by tongue portions (25) of the runners (5). The blocks each have two adjacent transverse rods (1) retained to them. The transverse rods are also connected by links (3) alternately arranged against external surfaces of the blocks (4) and in grooves (18) in the blocks where they are connected to the rods.

Abstract: 1-Aminoethyl, 1-aminopropyl and 1-aminobutyl derivatives of 7,7-dimethylnorbornane are described. The amino groups are optionally substituted, for example by alkyl groups, or may be saturated heterocyclic amino groups. The alkylene group at the 1-position can also be substituted, and the 2-position can be substituted by chlorine. The compounds have CNS activity.
