Abstract: Gear shifting device for a cycle having a chain and pinion transmission is provided, which includes a mobile gear shift assembly adapted to laterally displace the chain for enabling passage from one gear to another gear; transformation elements for transforming rotation of at least one pivoting gear into a lateral displacement of the mobile gear shift assembly; and a control mechanism for controlling lateral displacement of the mobile gear shift assembly. Further, the gear shifting device can include an indexing mechanism to further ensure exact positioning of the gears.

Abstract: A connector for a cable which includes a housing and the two clamping strips which are bent at their front ends and extend outwardly from an opening in the housing.

Abstract: A swivel-truck bakery oven having a baking chamber, a charging door, an electric control box, a recirculation channel, a re-circulation fan, heating elements for heating the re-circulation air, mechanical and power equipment for rotatably driving the swivel truck, and a blowing manifold with vertical louvres and a steam generator. The oven consists primarily of a generally rectangular frame structure, with the frame structure having a central core of parallelipipedic configuration with a width substantially corresponding to the width of the charging door, which is determined, in turn, by the width of the swivel truck. The frame structure also has a pair of detachable lateral covers which each have an interior recess or cavity of a depth that is slightly greater than half the difference between the width and the diagonal length of the swivel truck.
