Abstract: A combination shovel broom tool that includes a shovel blade, a broom mounted behind the blade and including bristles that extend downwardly and terminate in a bristle working surface such that the blade and bristle working surface can simultaneously clean a surface as the device is pushed along the surface to be cleaned and a wheel set disposed within the bristles to facilitate such pushing action.
Abstract: An improved trachea suction system includes a suction catheter with a high efficiency suction control valve providing unobstructed fluid flow in its activated suction applied mode for removal of viscous secretions at a low level of applied input suction through the catheter. The valve also non-restrictive to air flow at the distal tip of the catheter. The valve ideally part of a closed tracheal suction system having a catheter isolator seal with a vortex action catheter cleaning chamber located in front of the isolator seal which takes advantage of the high efficiency characteristics of the suction control valve.
Abstract: A heat sink assembly wherein the heat sink is allowed to move within vertical limits with respect to a clip adapted to hold both the heat sink and a microprocessor so as to accommodate heat expansion of the resultant assembly yet provide continual heat transfer contact between the heat sink and the microprocessor.
Abstract: A tracking system for ammunition cartridges where the cartridge casings are provided with serial indicia on an inside surface such that spent casing found at a crime scene can be tracked to the purchaser of the ammunition via a machine scannable system.
