Abstract: A condition-sensing handgun holster has been developed that both allows one-handed loading or unloading of a semi-automatic pistol using a slide mechanism, and that may sense the presence of a firearm in the holster as well as its load state, is described. The holster facilitates firearm loading and unloading through use of a gun slide-arresting mechanism that allows the gun carriage to move relative to the slide, introducing or ejecting a round into or from the chamber. Gun presence in the holster and load state are determined using in-holster sensors. The data may be transmitted to remote monitors.

Abstract: Successive carrier-length sections in which paper articles have been inserted, such as photoprints and negatives, are torn from the multi-leaf carrier stock along transverse score lines at successive interval locations along the stock. Initially bound together along only one longitudinal edge while incorporated in the body of the stock, two leaves of each carrier-length section become bonded together also at one end thereof when a carrier-length section is severed from the main stock by tearing it off along the transverse score lines, and in the act of tearing, withdrawing a portion of an intervening third lead from between the two other leaves so as to permit interengagement of contact adhesive patches pre-applied thereto.
