Abstract: A process is provided for converting 1-hydrogen-triazolo[4,3-a]-[1,4]benzodiazepines, e.g., estazolam, to 1-(hydroxymethyl)-triazolo-[4,3-a][1,4]benzodiazepines, and, if desired, these 1-(hydroxymethyl)-compounds to 1-aminomethyl compounds, e.g., to adinazolam, without the need for column chromatography or sealed tube procedures, and while minimizing 1,4-bis-(hydroxymethyl)- group formation.

Abstract: The present invention provides novel 4-phenyl-triazol-3-yl- and 3-phenyl-triazol-4-yl-piperidines which are useful as analgesics.

Abstract: An electrically-fired gun, of the type having a breechblock slidable in a transverse passage across its breech, has a retractor mechanism mounted within the breechblock for retracting the firing pin electrode tip behind the face of the breechblock as it opens and closes. A retractor lever connected to the firing pin is controlled by positioning means comprising spring means biasing the lever in one direction, and a plunger cam cooperable with a wall of the transverse passage to displace the lever in an opposite direction. The positioning means serve to retract the firing pin when the breechblock is opened for reloading, and to extend it on reclosing.

Abstract: An industrial gun, of the type having a transverse sliding breechblock, has a firing mechanism which automatically cocks and then releases a hammer as the breechblock closes. A sear is pivoted in the yoke or receiver of the gun in a position to engage and cock a hammer carried by the breechblock as the breechblock is moved from an open to a closed position. A cam surface on the sear bears against a cooperating cam surface on the hammer to release the hammer from the sear as the breechblock reaches the fully-closed position, in which a firing pin carried by the breechblock attains correct alignment with a shell in the gun chamber. A set screw provides an adjustable cam surface on the hammer to allow the correlation of the timing of the hammer release with the breechblock movement to be readjusted precisely as the parts wear with use.
