| 20100282880 | Paper Shredder Control System Responsive to Touch-Sensitive Element - The invention is directed to a touch-sensitive paper shredder control system. The touching feature is implemented through a series of electronic circuits, taking input from a conductive touch panel on the shredder feed throat, processing the signal, and through a motor driving circuit, stopping the mechanical parts of the shredder. The system has a touch detection circuit unit, which contains a bioelectricity controlled switching circuit to sense the conductive touch panel. The bioelectricity controlled switching circuit is configured to trigger a ground switching circuit in the touch detection circuit unit which outputs to a multifunction control circuit unit. The control circuit unit then takes care of the remaining protection issues. The touching device for paper shredders protects humans and other living beings including pets from injuries through automatic and real time monitoring. The complete control process is both safe and sensitive. | 11-11-2010 |
| 20110024535 | Safety Inlet Apparatus for a Paper Feed Opening of a Shredder - Safety inlet apparatus for a shredder paper feed opening includes upper cover, safety cover, paper feed passage block, and elastic member. A safety cover end section covers the shredder paper feed opening, and rotatably couples to the upper cover. Paper feed passage block is positioned between shredder paper feed opening and elastic member, and the safety cover pivots to the upper cover. Paper feed passage block is slidably arranged on the upper cover near shredder paper feed opening, connecting to the safety cover second end section. Elastic member ends respectively connect to the upper cover inner wall and the paper feed passage block. Paper feed passage block may be fixed to, or integrated with, the second end section, or may limit a stud on the second end section. | 02-03-2011 |
| 20110039483 | Apparatus and Composition for Sharpening a Paper Shredder Blade, and Preparation Process Therefor - Composition, apparatus, and methods of composition and apparatus manufacture, for sharpening a paper shredder blade. Composition includes grinding powder, thickening agent, and additive. The thickening agent may be a white oil, an animal oil, an vegetable oil, or a stearine wax. The additive may be an antirust powder, an antiwear powder, an antistatic powder, or an antioxidation powder. The grinding composition is dispensed into a polyethylene film, and sealed to form the grinding apparatus, as a grinding sheet or a grinding packet. A method for forming a grinding sheet includes selecting the constituent materials for a grinding composition; stirring the constituent grinding composition materials; heating the constituent materials to melting; mixing the constituent materials, while melting and intermixing; cooling and packaging the grinding composition to form a grinding sheet or packet. | 02-17-2011 |
| 20110072876 | New-Type Thin Shredder Blade Having Blade Points without Steps, Blade Sets and Manufacturing Method Thereof - The present invention provides a new-type thin shredder blade having blade points without steps, comprising at least one blade body and at least one cutting part that is located on the periphery of the blade body and includes a blade point, wherein the cutting part further comprises a protrusion which protrudes from the cutting part and includes a top, a inclined plane extends between the top and the blade point, and an acute angle is formed by the inclined plane and the blade body, preferably, the inclined plane is an inverted triangle, the cutting part further includes a first hemline and a second hemline extending respectively from the blade body and intersecting to the 10 blade point, a first plane extends between the top and the first hemline and intersects with the inclined plane, the blade body includes at least one large protrusion which protrudes in the same direction as the protrusion, the blade sets formed by the above-mentioned new-type thin blades and the manufacturing method of the above-mentioned new-type thin blades are also provided, with the blade sets formed by the new-type thin shredder blade having blade points without steps of the present invention, the shredder can reduce the production cost and the energy consumption greatly, while meet the same cutting requirement of the common shredder entirely. | 03-31-2011 |
| 20110133008 | PERMITTIVITY-BASED PAPER SHREDDER CONTROL SYSTEM - The invention is directed to a permittivity-based paper shredder control system. The touching feature is implemented through a series of electronic circuits, taking input from a conductive touch panel on the shredder feed throat, processing the signal, and through a motor driving circuit, stopping the mechanical parts of the shredder. The system has a touch detection circuit unit, which contains a bioelectricity controlled switching circuit to sense the conductive touch panel. The bioelectricity controlled switching circuit is configured to trigger a ground switching circuit in the touch detection circuit unit which outputs to a multifunction bioshield controller. The bioshield controller then takes care of the remaining protection issues. The touching device for paper shredders protects humans and other living beings including pets from injuries through automatic and real time monitoring. The complete control process is both safe and sensitive. | 06-09-2011 |
