| 20120024991 | FORCE RESPONSIVE SHREDDER - A shredder includes a cutting assembly capable of shredding paper mounted in a shredder housing and a detector mechanism capable of shutting off the cutting assembly in response to detecting a force applied to the cutting assembly. | 02-02-2012 |
| 20110210194 | SHREDDER WITH SLOT GUARD - A shredder includes a shredder housing with a top head and a shredder mechanism receptacle. The top head has at least a first slot for receiving articles to be shredded. The shredder mechanism receptacle is connected to the top head for receiving a cutting assembly capable of shredding paper. A safety device is disposed in the shredder housing. The safety device includes a slot guard and gear system for selectively blocking the first slot. | 09-01-2011 |
| 20100181398 | OVERLOAD FAULT CONDITION DETECTION SYSTEM FOR ARTICLE DESTRUCTION DEVICE - An article destruction device includes an electric motor driving at least one moving component. An indication panel includes at least three visual indicators situated in sequence. Each visual indicator is associated with a stage of an approaching overload (motor cool down) condition. A first visual indicator lights when the motor or corresponding sensor temperature is below a first threshold, i.e., when the device is first powered on. A second indicator lights when the temperature exceeds the first threshold and is below at least a second threshold, i.e., the temperature is approaching a fault condition. A last visual indicator lights when the temperature exceeds the first and the at least second thresholds, i.e., the fault condition is met. A thermistor on the motor energizes (self-heats) with the motor. A thermostatic switch controls current flow through windings of the motor depending on measured temperatures meeting operating and equilibrium temperature thresholds. | 07-22-2010 |
