Latest Patents

Laithwaite's latest patents include a system designed for sorting non-ferromagnetic metals from a mixture of materials that also contain rubber and plastics. This system features a conveyor belt and an associated linear induction motor. The frequency and power of operation of the motor are specifically chosen to deflect selected metals from the conveyor belt. The linear induction motor is strategically placed beneath the conveyor belt, oriented to produce a field of magnetomotive force. This field's lines are at right angles to the conveyor's direction of motion, ensuring effective separation of materials. The initial treatment of the mixture, such as presizing or flattening, enhances the induction motor's effectiveness in separating non-ferromagnetic materials.
