Abstract: Barriers for contravention of the transfer of pathogenic organisms from one patient to another through an inflatable cuff comprised of a cuff and a bladder of a sphygmomanometer are supplied on a sterile roll of synthetic polymer segmented by transverse perforations so that each segment may be torn off and used as a barrier between a patient's skin and an inflatable cuff. The rolled segments may be tubular so that the barrier will be tubular in form in order to slip it over the patient's extremity. Each tubular barrier is perforated along one edge so that it can be torn longitudinally to convert the barrier from a tubular form to a rectangular form if needed. The tubular form is provided with ample circumference so that the excess can be gathered near the longitudinal perforations and folded over the longitudinal perforations in order to maintain the integrity of the barrier's function.

Abstract: A method is disclosed for placing a semiautomatic pistol, such as a Glock pistol (or any other type of pistol having a recoiling slide on a frame for both loading another cartridge from a magazine and cocking the trigger mechanism of the pistol), in a condition of absolute safety for deployment. That new condition is with a cartridge in the chamber of the pistol and its trigger mechanism uncocked. The method is carried out by separating the slide from the frame of an uncocked pistol, partially disassembling the slide to place a round on the breech face of the chamber and reassembling the slide with the chambered end of the barrel over the cartridge. The slide is then replaced on the frame by drawing it back over a spring-loaded slide lock. The trigger mechanism may then be cocked when the pistol is deployed by drawing the slide back an extent necessary and sufficient for that purpose without engaging a mechanism for loading another cartridge in the chamber.
