Title: Hydrocyclones, particularly pulp cleaner cones of the canister operated type
Inventor: MACFARLANE WILLIAM E
IPC: B04C5/08
Filed: 1985-08-02
Granted: 1991-07-23
Abstract: HYDROCYCLONES, PARTICULARLY PULP CLEANER    CONES OF THE CANISTER OPERATED TYPE            Abstract of the Disclosure A hydrocyclone, particularly a pulp cleaner cone, of the canister operated type is formed of a slightly yieldable or flexible material such as polyurethane molded as two main parts, a main cone body having a generally conical vortex space or separation chamber into which a suspension or slurry feed port and a rejects or underflow outlet port open, and a closure member or vortex finder body containing an accepts or overflow outlet for the finer fraction separated from the suspension.  The vortex finder body is mounted in the base end of the hollow vortex space, and has a pro-jecting portion formed with a grip area for gripping by an extraction tool to remove the cone from the canister for inspection, unplugging, etc.  An improved connec-tion between the main cone body and the vortex finder body, to cope with the substantial pull forces of the extraction tool, comprises axially spaced wedge-shaped projections or ramps extending in ring-like form about the vortex finder body and interfitted with corre-sponding wedge-shaped grooves in the interior wall of the main body.  Assembly is by forcibly inserting the vortex finder until the wedge projections and grooves interfit to hold the vortex finder body firmly in the main body.  An adhesive may be used for additional holding power and sealing.  By using a polished molding tool, the interior surface of the vortex space or separation chamber is made extremely smooth.

Title: Soft-start electromagnetic coupling

Filed: 1988-03-29
Granted: 1991-06-18
Abstract: SOFT-START ELECTROMAGNETIC COUPLING             Abstract of the Disclosure The rotor and armature of an electromagnetic clutch are formed with multiple regions of high magnetic reluctance defined by slots which are shaped and located such that the radial relation between the slots of the rotor and the slots of the armature changes as one member rotates relative to the other. As a result, the flux density across the air gap between the rotor and the armature varies when the armature slips relative to the rotor during initial engagement of the two.  This lowers the average torque transmitted by the rotor to the armature and allows the clutch to engage gradually or with a soft-start before building up to full torque.
