Separation of hydrophobic particles from a mixture of particles in a fluid is performed by providing a fluidized bed as a relatively non-turbulent contacting mechanism in a flotation cell incorporating a settling chamber located immediately above the fluidized bed. Hydrophobic particles attach to bubbles in the fluidized bed and rise to the interface with the settling chamber where non-hydrophobic particles flow over the lip of an internal launder and are removed as tailings at. The hydrophobic particles attached to bubbles float upwardly in the relatively placid settling chamber where unwanted gangue can fall back to interface. The bubbles form a froth layer at the upper surface of the settling chamber, and flow over the launder lip carrying the hydrophobic particles. An operation of the apparatus is kept stable by recirculating fluid from the settling chamber via pip and pump to mix with new feed entering at duct.

The present invention relates generally to a mechanism of a contact system for circuit breakers. More particularly, the invention encompasses a mechanism for a rotary double-break contact system, which enables a direct transfer of torque from stored energy components, such as, springs, to the contact arm in the ON-position (contacts closed) without using intermediate cam surface. The mechanism described in the invention also ensures reliable locking of the contact arm in the blow-off position using stationary means that are integral with or fixed to a crossbar module. This invention enables to achieve significant reduction or even to eliminate friction at certain critical interfaces between the contact mechanism components, thus, reducing or potentially eliminating hysteresis, and improving performance consistency, and also eliminating mechanism performance dependency on wear level and condition of an intermediate cam surface. An additional feature of this invention is a reduction of a loss of contact torque / force during over-travel in the ON position when the fixed and / or moveable contacts erode. Configurations described in this invention may also feature physical protection for the moving components of the contact mechanism assembly from flying particles resulting from short circuit shots.

An emergency stop switch mechanism for a robot which can take an emergency position when an external operation force is released and when a strong external operation force is applied. When the robot operation is started, a main lever La is pushed down from the OFF state with a normal external operation force. Since an elastic biasing force S2 is sufficiently larger than S1, a second ancillary lever Lc is pushed by a plunger PL and is turned downward together with a first ancillary lever Lb. A movable contact element ME of a contact mechanism section CM is moved to the ON position by the second ancillary lever Lc, so that the ON state (motion permitting state) is established. If emergency stop becomes necessary, the pressure of the main lever La is released from this state, or a specially strong force is applied to the main lever La. When the former is selected, the movable contact element ME is returned to the OFF position. When the latter is selected, a strong torque is applied to an axis AX2, so that the first and second ancillary lever Lb and Lc become in a bent state. As a result, the OFF state is established, by which the robot is stopped.
