Patent CA-2291500-A1 (CA)
Inventor: EYRAUD PHILIPPE
IPC: B01F13/08
Filed: 1999-12-02
Abstract: The rotor can be moved in translation parallel to the X-X' axis inside the sleeve between a first position where the two means of coupling are matching to drive the helix in rotation and a second position where they do not interact or interact little, so the helix can be displaced relative to the sleeve without the two couplings interacting  The agitator comprises a union (5) which can be mounted in a sealed fashion in a wall (2a) of a receiver with a blind sleeve (10) inside which is fitted a rotor (20) supporting a first magnetic coupling (21). A helix (8) placed around the sleeve is equipped with a second magnetic coupling (17) to drive the helix around an axis (X-X') of rotation. The rotor can be moved in rotation around and parallel to the axis X-X' by a drive shaft (22) which is itself movable in rotation around and parallel to the X-X' axis between two positions corresponding to those of the rotor. The rotor has a central hollow to receive a screw for mounting the rotor on the shaft, with the screw placed along the X-X' axis. The rotor and/or shaft can be immobilized during their parallel movement in an intermediate position. The drive shaft is mounted to slide inside a hollow shaft which is the output from a reduction gear, with the two shafts fixed together in rotation. The hollow shaft has a screw which acts with a fillet fixed to the drive shaft. The parallel movement is controlled by a hydraulic or pneumatic jack. Process of controlling couple transmitted to a magnetic agitator as described above by controlling the position of the rotor along the X-X' axis.

Filed: 2000-11-16
Abstract: An automotive vehicle has a transmission through which an engine can deliver torque to an axle to propel the vehicle and a transfer case associated with the transmission for operating auxiliary equipment. A system for engaging and disengaging the axle from the transmission and for engaging and disengaging the auxiliary equipment contains a first solenoid (20) that operates to a first state when the vehicle is to be propelled and to a second state when the auxiliary equipment is to be operated and a second solenoid (22) that is selectively operable to a first state that causes the auxiliary equipment to be disengaged from the transmission and to a second state that causes the auxiliary equipment to be engaged with the transmission through the transfer case. A module (26) controls the solenoids and receives a first input (14, 18) for requesting concurrent operation of the solenoids to their respective second states, a second input (16) for signaling transmission output shaft speed, and a third input (24) for signaling full engagement of the auxiliary equipment with the transmission through the transfer case.  Once the third input has signaled full engagement of the auxiliary equipment with the transmission through the transfer case, the module prevents both disengagement of the auxiliary equipment from, and engagement of the axle with, the transmission until the second input signals a speed predetermined to be a speed suitable for allowing both disengagement of the auxiliary equipment from, and engagement of the axle with, the transmission.
