摘要： A system and method is claimed for protecting sections of a buried utility pipe that will eventually be excavated and exposed for tapping purposes. The system includes a protective collar that is applied to the utility pipe before the utility pipe is buried. When the utility pipe is to be tapped, the utility pipe is excavated directly above the protective collar. The presence of the protective collar provides a physical barrier that prevents the utility pipe from being damaged from the excavating equipment. When the protective collar is removed, a clean, unobstructed area of utility pipe is exposed on which a tapping procedure can be performed.

摘要： A shredder has a jam proof system with a thickness detector having a contact member which displaces as an article is inserted into the shredder and a resistance generating mechanism which provides a resistance force to the contact member, in response to its displacement. The greater the thickness of the article, the greater the resistance force realized. When a predetermined thickness is reached, there is a significant change in the resistance force. The resistance generating mechanism may include at least two spring mechanisms and provide feedback to the user that the inserted article may be too thick. In addition, the thickness detector may include a thickness sensor. The sensor may communicate with a controller to alert the user, and/or alter the operation of the shredder, in response to the thickness of the inserted article. For example, the controller may visually and/or audibly alert the user, or control shredder motor response.

摘要： An assembly has a bin level detection system having at least one sensor positioned to receive radiation reflected off any material deposited in a bin and to determine an intensity of the reflected radiation. The intensity corresponds to an amount or level of shredded material deposited in the bin. The system may detect radiation from one or more emitters, or, alternatively, detect ambient light entering the bin via a window. A level indicator system may also be provided to indicate the amount of material deposited in the bin, including if the bin is full. The assembly may comprise a shredder and a shredder housing.

摘要： Disclosed herein is a shredder having a throat for receiving at least one article to be shredded therethrough and a shredder mechanism received in a shredder housing which is driven to shred the at least one article fed therein. At least one sensor emits and detects radiation to detect the presence of the at least one article or shredded particles. The sensor communicates with a controller to operate the shredder mechanism. The controller also calibrates an intensity of the radiation of the sensor(s) to or within a predetermined amount above a minimum level in order to reduce wear and run-on conditions.

摘要： A shredder is disclosed having a gas detection system. According to one embodiment, one or more sensors may be placed inside the housing of the shredder to detect the presence of gases, and in particular, flammable or combustible gases. If a gas is sprayed into the shredder, the sensor(s) will detect the gas and the shredder may be deactivated. In addition, an exhaust fan may also be activated to purge the gas from the housing. Further, one or more indicators may be provided to alert the user that the sensor has detected gas. For example, a visible signal and/or audible sound may be generated to alert the user that the sensor has detected a flammable or combustible gas.
