Shredding (disassembling genomic data)

Abstract: A piston-and-cylinder retarder delays the switch opening of a switch actuated by a sensor in the path of paper introduced through the paper-feed shaft or chute of a paper shredder, thereby eliminating the need for more expensive and complex electronic time-delay systems to ensure that the shredding unit remains switched on until the trailing edge of the paper passes it.

Abstract: This invention is related to a dual-functional medium shredding machine structure, specifically designed for shredding or destroying paper printed with data to be destroyed, optical discs containing data to be destroyed, or expired credit cards. This invention mainly implements a pair of shredding roller blades with sharp teeth as shredding means, and is characterized by providing separate feeding inports, including a paper inport for feeding paper in an inclined orientation, and a disc inport for feeding discs in a vertical orientation, wherein the inports are each led to the same shredding roller blades such that, regardless of the type of substance being fed by the user, the paper or the discs can both be shredded by the shredding roller blades, and the shredded scraps are dispensed to separate collectors through an identical exit by means of an auto-revolving switch plate; and a touch switch at each of the inports such that, while feeding the paper or the discs, the touch switch activates the shredding roller blades to perform shredding task, and drives the switch plate so as to dispense shredded scraps of different substance into different collectors.

Abstract: A method of disinfecting medical materials, which comprises heating medical materials and exposing the medical materials to gamma radiation, is provided. One method of heating is the application of radio-frequency waves. The medical materials are subjected to radio-frequency waves for at least approximately 5 minutes and to gamma radiation measuring at least approximately 0.25 Mrads. When the starting material consists of pre-sorted medical or veterinary waste, the method further comprises shredding the irradiated waste and recycling the shredded waste.

Abstract: In the disposal device for paper documents according to the present invention, the feeding of paper that is to be disposed can be done either automatically with a feeding unit or manually from a manual inlet. Therefore, the disposal of sensitive paper documents can be carried out sheet by sheet by placing the paper on the automatic paper feed unit while paper documents which do not require any security measures may be manually fed into the disposal device for an immediate shredding process. Therefore, the present invention allows both appropriate and efficient disposal of paper documents without regard to whether the paper documents to be disposed require security measures or not.
