  • Method and apparatus for preventing flamespread in an equipment assembly
    Patent number: 6327155
    Abstract: A printed circuit card assembly for preventing flame spread in an equipment assembly includes a printed circuit board having first and second sides, at least one of the first and second sides of the printed circuit board adapted for mounting a plurality of electronic components thereon; and a heat absorbing flame resistant shield facing one side of the printed circuit board for absorbing heat energy from an adjacent printed circuit card assembly thereby reducing heat transfer to the printed circuit board.

  • Portable modular apparatus and method for destroying medical needles
    Patent number: 5868709
    Abstract: A portable electronic (electro-mechanical) device for destroying sharp, contaminated hypodermic and other medical needles includes an upper electrode assembly, two fixed, and one moveable electrode situated between the two fixed electrodes. The moveable electrode comprises a chamber to contain residue and sparks generated from closing an electrical circuit. An electronic control circuit controls the modulation of the moveable electrode in relation to the two fixed electrodes and automatically manages the destruction cycle of said needle by use of electro-mechanical sensors and motors. The sharp end of said needle is inserted through an opening in the upper electrode and contacts the lower fixed electrode. Any gases generated by the incineration process are drawn through the disposable burn head by a fan and are filtered by a multi-stage filteration system before being passed into the local ambient surroundings. The portable apparatus is modular.
