Patent CA-3020184-A1 (CA)
Inventor: ANDERSON MATTHEW HENRY
IPC: B60L11/18
Filed: 2017-04-07
Abstract: Autoscrubbers are capable of being operated in a manual (e.g. walk-behind) mode and an autonomous (operator free) mode and capable of switching between such operational modes. Apparatus and methods for steering such autoscrubbers use steering torque mechanisms to apply steering torques independently to left and right drive wheels. Steering systems for autonomous operation may be retrofit onto existing walk-behind autoscrubbers to implement this functionality. The autonomous control capability may not detract appreciably from an operator's ability to use the autoscrubber in a manual (walk-behind) mode.

Title: Hydro-viscous speed regulating device for heavy-load start of belt conveyor
Inventor: MENG QINGRUI
IPC: F16D25/10
Filed: 2017-12-12
Abstract: A hydro-viscous speed regulating device for heavy-load start of a belt conveyor comprises an input shaft and an output shaft connected through a spline tube, an inner and outer friction plate set being controlled by an inner and an outer oil cylinder respectively. Oil inlet and oil return of the inner and outer oil cylinders are controlled by oil inlet and oil return valve cores automatically. In a starting process, pressure oil enters the outer oil cylinder, and engages the outer friction plate set to provide torque required by the output shaft. When the starting process completes, the output shaft's revolving speed rises; the oil inlet and oil return valve cores move outward under a centrifugal force; the pressure oil enters the inner oil cylinder and engages the inner friction plate set to provide torque required by the output shaft, and oil returns to the outer oil cylinder.
