Abstract: A conveyor system comprising a conveyor and a conveyor weighing apparatus. The conveyor weighing apparatus has a load determination device for determining the load exerted the conveyor on a conveyor support. The conveyor weighing apparatus may have measurement devices for measuring the angle and speed of the conveyor. The load determination device determines the load exerted by the at least section of conveyor in both laden and unladen states, and the results are combined with the speed and angle measurements, and with known system constants, to calculate the weight of material being conveyed.

Abstract: A machine such as a material processing apparatus comprises a mechanical transmission system coupled to a mechanical load such as a crusher. An internal combustion engine is coupled to the mechanical transmission system, and at least one motor-generator is coupled to an electrical system and to the mechanical transmission system. In at least one mode of operation, the electrical system delivers electrical power to the motor-generator(s), the motor-generator(s) generating mechanical power from the electrical power and delivering the mechanical power to the mechanical transmission system to drive the mechanical load.

Abstract: A material processing device has a rotor coupled to a rotatable shaft, and a rotor control system. The rotor control system comprises a rotor control mechanism with a first engagement member that is engagable with a second engagement member coupled to the shaft. The rotor control mechanism is operable into and out of an engaged state in which the first and second engagement members are engaged with one another. In the engaged state, the rotor control mechanism is operable in a locking mode in which the first engagement member is fixed in position to prevent rotation of the shaft, or in a rotation mode in which the first engagement member is movable to rotate the shaft. The material processing device may be a crusher, a shredder or a milling machine.

Abstract: An aggregate processing apparatus comprising a conveyor support structure having a base section located at a side of the apparatus, a mid-section pivotably coupled to the base section and a head section pivotably coupled to the mid-section. The conveyor support structure is operable between a deployed state, in which the mid-section and the head section project from the side, and a transport state in which the mid-section is folded to extend across the first face and the head section is folded with respect to the mid-section to extend across an end face of the apparatus.

Abstract: A mechanism for reducing common-mode current in a system including a first subsystem and an isolated subsystem. The isolated subsystem may receive the common-mode current from the first subsystem via an isolation mechanism. The isolation mechanism (e.g., a transformer) may isolate the isolated subsystem from the first subsystem by blocking DC signals. The first subsystem may include a pulse generation unit and compensation circuitry. The pulse generation unit may provide a first pulse and a second pulse to the compensation circuitry. The phase and duty cycle of the pulses may be varied based on measured characteristics of the isolation mechanism. The compensation circuitry may generate a cancellation signal based on the first and second pulses. Furthermore, the compensation circuitry may provide the cancellation signal to a ground plane of the isolated subsystem to reduce the common-mode current received at the isolation subsystem.
