Abstract: A self-loading pistol holster has a locking mechanism for the slide consisting of a pinion protruding into a depression of the slide bar, preventing movement of the slide bar. As the spring-loaded button is pushed the geared pinion is rotated to reveal a flat portion to the depression, enabling movement of the slide bar. A spring-biased latch within the holster which holds the trigger guard of the pistol is also disengaged simultaneously on application of the button, releasing the pistol for removal from the holster. Within the holster is a rubber barrel plug which seals the pistol barrel while the pistol is in the holster. The holster is removably mounted on a bracket having upper and lower retention points by means of a lever lock unit, and the bracket may be attached to belt, vest or leg mounts.

Abstract: A structure printer for printing structures that has a stable platform on which a swiveling base is mounted. A boom is extendible from the base having a plasmatron mounted on the end of the boom for heating and melting the building material, which may subsequently be sprayed by a print head that receives the molten material from the plasmatron, the print head having an adjustable nozzle for expelling the mixture in a specific location. The printer may be vehicle-mounted, and may have a computer control so it is able to print a building faithfully from a blueprint. The building material may be foam glass, or other mixtures may be used.

Abstract: A pistol holster is disclosed that permits a pistol to be loaded while within the holster. To effect this, the holster body containing the lower portion of a pistol, slides downward relative to a slide bar component that holds the breach block of the pistol, allowing a live round of ammunition to be loaded into the pistol's firing chamber with a single hand action, to make the pistol ready for firing. The holster also contains one or more locks to prevent unintentional removal of the pistol from the holster.
