|20140021890||COMMINUTING MACHINE DRIVE SYSTEM - A comminuting machine includes a frame, a comminuting rotor coupled to the frame, and a rotary drive coupled to the rotor. The rotary drive including a controller, a multi-phase motor connected to the controller, a set of contactors disposed between the controller and the multi-phase motor for selectively providing driving motive force to the multi-phase motor, and at least one rheostat disposed between the controller and the multi-phase motor, in parallel with the first set of contactors, for selectively providing a stopping resistance to the multi-phase motor to effect frictionless braking of the comminuting rotor, wherein the controller is configured to operate the set of contactors and the at least one rheostat to single phase lines of the multi-phase motor for providing the stopping resistance.||01-23-2014|
|20110315025||SHEAR DEFLECTION ANGLE DETECTION - A recycling machine deflection detection system including a cross head movable within a shear box of a recycling machine, one or more sensor units disposed on the cross head, and a controller connected to the one or more sensor units, the controller being configured to receive deflection signals from the one or more sensor units and determine, from the deflection signals, a shear deflection angle of the cross head due to deformation of the cross head.||12-29-2011|
|20110226106||SHEAR DEFLECTION DETECTION - A through beam shear angle change, cutting blade deflection detector including a cutting member within a shear box of a recycling machine, a through beam sensor including an emitter disposed on the cutting member and a receiver disposed on the cutting member, the receiver being disposed relative to the emitter for receiving a signal emitted from the emitter, and a controller connected to at least the receiver, the controller being configured to determine an amount of cutting member deflection based on an output of the receiver.||09-22-2011|
|20110215181||COMMINUTING DEVICE WITH REMOVABLE BEARING - A comminuting device for comminuting material. The device has a frame and a shear member having a main blade, the shear member movably coupled to the frame with a shear member slide bearing located at least partially inside the frame. A supporting table is coupled to the frame, the supporting table having a counter blade, the supporting table adapted to support the scrap material. The frame has an opening forming an access way to the shear member slide bearing. The main blade and the counter blade cooperate to chop the scrap material when the shear member is moved from a first position to a second position. The shear member slide bearing is removable from inside the frame through the opening without removal of the shear member from the frame.||09-08-2011|
|20110206537||HYBRID ELECTRO-HYDRAULIC POWER DEVICE - A hydraulic power device for effecting operation of at least one load, the hydraulic power device including a motor having a predetermined motor speed rating and motor power rating, at least one pump operably coupled to the motor, the pump being configured to provide, to the at least one load, a predetermined hydraulic fluid flow at the predetermined motor speed rating, and a variable frequency drive connected to the motor, the variable frequency drive being configured to effect operation of the motor at a speed above the predetermined motor speed rating such that the at least one pump operates to provide an excess hydraulic fluid flow during operation of the motor substantially above the predetermined motor speed rating where the excess fluid flow is greater than the predetermined hydraulic fluid flow.||08-25-2011|
