Abstract: PURPOSE:To provide a wet pan that is simple in structure, easy to maintain, inspect, and produce, and low in production cost and is enhanced in mixing performance using a small power to contribute to resource savings and energy savings. CONSTITUTION:A pan 7 rotates integrally with a drive shaft 9. A main tire 1 is supported by bearings 8 and brought into linear contact with a bottom pan plate 6. The main tire 1 rotates by a frictional contact force produced by the rotation of the pan 7. If a slip phenomenon occurs when a material having a small frictional force is kneaded and jams the rotation of the main tire 1, a rotational force is transmitted to the main tire 1 by the contact force of a sub-roller (a wear-resistant hard rubber lining) 2 connected to a drive speed-reduction motor 3 by a chain. By changing over an air circuit by an air change-over valve 10, the sub-roller 2 is pulled up by a pressurizing cylinder 5 to make the main tire 1 in a free rotation state.

Title: Abnormal speed detecting device for handrail of carrying belt
Inventor: UEHARA TETSUO
IPC: B66B29/00
Filed: 1990-03-29
Abstract: PURPOSE:To detect abnormality of the moving speed of a carrying belt and a handrail by providing an idle wheel reversely rotating in the same speed against a driving roller and an expansion detecting part to detect expansion of a crank arm connected through a pin on the same radius of a driven roller synchronizingly rotated with the driving roller. CONSTITUTION:When an escalator is normally operated, a crank bar 11 is operated in normal crank motion and the length is kept into a constant value, and a displacement detector is not actuated. When a moving handrail 7 is applied with overload very close to the setting value, or with intentional force in the reverse direction by mischief and the like, or in the worst case movement of the moving handrail 7 is obstructed, rotating speed of a synchronized driven roller 8 is slowed and difference of rotating speed is generated against an idle wheel 10. Hereby, the crank mechanism can not maintain normal crank motion, and the crank bar is expanded or contracted. This displacement is detected with a displacement detector, and a speed difference generation detected signal is output.
