Abstract:
A wood grinding machine may have a vibration detection system including one or more vibration sensors. The vibration detection system may include a trip point representative of a maximum allowable level of vibration. If a vibration signal from the one or more vibration sensors exceeds the trip point, a trip protocol may be executed to automatically stop the grinding process. Related methods are also disclosed.

In an aspect, a stopper receivable in an inlet of the food waste disposer includes or is couplable to a power source which in an aspect is a rechargeable power source and in an aspect, is disposed in a housing of the stopper. In an aspect, the stopper includes a cord for coupling the stopper to the power source which is a source of AC power.
Abstract:
A shredding machine for domestic or office use having a feed passage 3 leading to a cutting mechanism 10, 11 powered by an electric motor, has a thickness measuring device 15 for measuring the thickness of bundles of paper fed through the feed passage and the machine is controlled by a microprocessor which receives signals from the thickness measuring device and prevents the cutting mechanism from being energized if the thickness measured is above a threshold determined by the microprocessor. The microprocessor varies the threshold in accordance with electrical supply voltage, the electric motor temperature and the electric current drawn by the motor during a previous shredding operation, so that the maximum thickness the shredder will accept can be reduced automatically when motor temperature increases or as the effectiveness of the machine deteriorates throughout its working life.
Abstract:
A system for shredding medical waste, the system comprising a medical waste treating chamber being an interior of an enclosure disposed within an environment which is not to be polluted, a motor, a shredder seated in the chamber and including a motor-driven shaft and blades rotated by the shaft, the shaft extending through the enclosure thereby to define an interface between the waste treating chamber and the environment, and interface seal apparatus preventing leakage of at least fluids from the medical waste treating chamber into the environment, via the interface.
Abstract:
A shredder includes a cutting mechanism operable to shred material fed thereto. A controller is coupled to the cutting mechanism to control the on/off state and the direction of rotation of the cutting mechanism. An interactive user interface is coupled to the controller. The controller is configured to detect a jammed condition within the shredder and communicate a series of instructions to the interactive user interface to instruct the user how to clear the jam.

Abstract:
Provided is a shredder that prevents particles from jamming in a shredding mechanism at the time of shredding sheet-like objects, and maintains shredding performance. A cleaning mechanism (10) for cleaning cutter elements (4) in a pair as a shredding mechanism (3) includes: first partition members (11) arranged in a plurality of stages to cover peripheries of spacer portions (6) of the cutter elements (4) in a pair, the first partition members (11) being configured to remove particles (1a) from an inside of recessed portions (7) of the cutter elements (4) in a pair; and second partition members (12) arranged in a plurality of stages to cover peripheries of cutter portions (5) of the cutter elements (4) in a pair, the second partition members (12) being configured to close gaps through which the particles (1a) enter between the first partition members (11).
Abstract:
A shredder includes a housing having a throat for receiving at least one article to be shredded, and a shredder mechanism received in the housing and including an electrically powered motor and cutter elements. The shredder also includes a detector that is configured to detect a thickness of the at least one article being received by the throat, and a controller that is configured to operate the motor to drive the cutter elements to shred the at least one article and to set a flutter threshold higher than the predetermined maximum thickness threshold, if the detected thickness is less than a predetermined maximum thickness threshold. The controller is also configured to thereafter continuously detect the thickness of the at least one article being inserted into a throat of the shredder; and to perform a predetermined operation responsive to the thickness detector detecting that the thickness of the at least one article is greater than the flutter threshold.
Abstract:
A shredder includes a shredding mechanism and a vibration sensor configured to detect vibrations generated by the shredding mechanism. The shredder includes a controller configured to regulate operation of the shredder's motor in response to the detected vibrations. The controller may regulate operation of the shredder so as to keep the detected vibrations below a predetermined vibration level during operation of the shredder. The controller may modify operation of the shredder (e.g., turn the shredder off, conduct an autocorrect sequence, increase or decrease the shredder's speed, display an error message) in response to the detected vibrations having a predetermined characteristic (e.g., frequency and/or amplitude within a predetermined range, a characteristic that indicates a material/paper jam or misfeed). The controller may change the predetermined characteristics over the life of the shredder to account for gradual changes to the shredder's baseline vibration characteristics as components wear in and out.
