  • Patent number: 8596564
    Abstract: True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. The cutting system includes a cutting blade, typically a rotary cutter, and a sacrificial plate or round bar contacting the cutting blade. The contacting portion has a zero clearance during the cutting operation. A metering mechanism is also provided which is capable of metering the material at a predetermined rate to the cutting blade. A mechanism is also provided for incrementally moving the sacrificial blade towards the cutting blade to ensure that the zero clearance is maintained between the cutting blade and the sacrificial plate, even when the sacrificial plate begins to wear down due to usage.

  • Patent number: 8297544
    Abstract: True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. Destruction of the material is further enhanced by advantageous strategic patterning of cutting edges on a rotary cutter, and further by secondary shredding features. For example, on the same axis as the rotary cutter, may be disposed, one on each end, rotating secondary shredders that receive material that has been cut by the rotary cutter as well as material that has escaped cutting by the rotary cutter. A variety of materials, of different thicknesses and types, may be reduced to a dust or powder-size.

  • Patent number: 8272854
    Abstract: This impeller-free vacuum cleaner is based on a rotary piston. Vacuum suction of 300 inches of water or better can be delivered. Quietness of below 70 db can be delivered. Tongued rotary piston assemblies may be strategically placed, such as stacked, to eliminate vacuum suction dead zones. Sealing problems that otherwise were encountered with previous reciprocating and rotary piston structures for vacuum cleaners are solved by using a tongued rotary piston with a double-notched rotary valve operating by a Geneva mechanism, and a novel pancake-shaped cylindrical structure to house the rotary piston. An inventive rotary combustion engine also is disclosed.

  • Patent number: 8211216
    Abstract: A particularly advantageous vacuum cleaner system has at least two filters and self-cleans its filters via back-flushing, without needing to stop normal operation to self-clean. Also, a self-cleaning valve assembly is provided for use in a vacuum cleaner. Also, a vacuum cleaner is provided that uses permanent, self-cleaning filters, and does not need disposable filters or filter bags, and advantageously can use inexpensive plastic bags. In another vacuum cleaner system, waste is collected in an ordinary plastic bag without any special preparation or modification of the bag being needed. Further, an inventive self-cleaning X-valve assembly cleans itself and is useable in the vacuum cleaner system.

  • Patent number: 8100353
    Abstract: Self-healing of a mechanical part in a mechanical system is provided, such as a self-healing part in a cutting apparatus. Differential hardness of respective parts in contact with each other is used. Undesirable damage from a foreign object in a mechanical system is managed by directing damage away from a part that is not wanted to be damaged and towards a part that may receive damage and be replaced. True zero-clearance cutting on a commercial scale is provided via a cutting area including a sacrifice material that is relatively softer than the cutter. One example is a cutting system which is capable of cutting a material such as, for example, tape or paper, into a fiber or powder. Destruction of the material is further enhanced by advantageous strategic patterning of cutting edges on a rotary cutter, and further by secondary shredding features.

  • Patent number: 7871025
    Abstract: A inventive feeding mechanism continuously feeds and continuously subjects to shredding, cutting, recycling, sorting, or other processing, a load consisting of a mixture of different-thickness materials, such as a mixture of paper, compact disks (CDs), cassette tapes, videotapes, etc. The auto-adjusting feeding mechanism is useable in high-security destruction, food processing, recycling, sorting, processing, and other applications.
