Abstract: The present invention features a firearm safety mechanism with an improved trigger pull, wherein the weight of the safety mechanism is not on the trigger when the hammer is in the “full cock” position. The advancement presented in the present invention serves to separate the trigger from the trigger bar during the period when the trigger is pulled. As a result, the weight of the safety mechanism is not borne by the trigger while the hammer is fully cocked. This is accomplished by providing means for positioning the transfer bar into the extended position free from contact with the trigger. The present invention further features means, dependent upon the trigger, for facilitating the relocation of the transfer bar from its extended position into a retracted position upon release of the trigger subsequent to discharge of the firearm.

A pivot arm extending generally horizontally has a vertical cylindrical pivotable end rotatably coupled to a pivot arm axle. A pivot arm support cable has a tree end coupled to the mounting bracket and a pivot arm end coupled to the distal end of the pivot arm. A cylindrical support leg extends vertically downward. A cradle is formed in the support leg.

Abstract: A frangible hollow point bullet is disclosed. The bullet (or slug) is formed from a frangible material such as sintered copper to provide a bullet-shaped body. A plurality of coaxial, substantially cylindrical cavities having progressively decreasing bore diameters are formed in the nose of the bullet-shaped body, extending rearwardly therefrom, to provide a bullet that both expands and fragments in a semicontrolled fashion upon impact with a target. In a preferred embodiment, at least one of the coaxial cavities is multiply scored to provide a substantially symmetric fragmentation pattern and controlled and uniform fragment size. Controlling the aggregate depth of the coaxial cavities enables the retention of a recoverable base or shank that is suitable for ballistic investigation following bullet impact.

Abstract: Contaminants within the gaseous emission discharged from an incinerator are eliminated during passage in parallel through reactor chambers by chemical reaction induced during exposure to plasma generated within said chambers. The plasma is generated by corona-discharge breakdown of electric fields established about electrodes within the reactor chambers upon supply thereto of electrical pulse voltage exceeding a critical field breakdown value inversely proportional to a high chamber temperature of the gaseous emission under atmospheric pressure within the reactor chambers.
