Abstract: A mounting apparatus for the quick-detachable securing of a flashlight or a like target illumination device to a firearm. The mounting device includes a passage for receiving the barrel of the flashlight or the like. The passage is provided with a resilient means to press the flashlight longitudinally along approximately the same axis as the firearm's barrel in opposition to a springably-positioned latch system engaging one end of the flashlight which prevents its dislodgment upon movement of the firearm during handling or discharge, yet enabling relatively quick, one-handed release and replacement of the entire flashlight. The flashlight or the like is prevented from rotating in the passage by a groove in the interior of the passage that engages part of the flashlight body thereby indexing it so that the flashlight's controls are always in the same position and accessible to the user.

Abstract: The present invention is a safety mechanism for single action firearms, the safety mechanism having a trigger block slidably engaged with a safety channel in the firearm's frame. The trigger block has a block lower region configured to engage the firearm's trigger such that rotation of the trigger to a hammer release position moves the trigger block from a lower trigger block position to an upper trigger block position. The trigger block also has a block upper region, configured such that, when the trigger block is in its upper trigger block position, the firearm's hammer can cause the firearm's firing pin to strike a cartridge in the firearm, and when the trigger block is in its lower trigger block position, hammer blocking means prevent the hammer from causing the firing pin to strike the cartridge.

Abstract: A firearm sight and mount for use on the muzzle end portion of a firearm barrel. The firearm sight is an optical sight with an artificially illuminated reticle and it and the associated mount are adapted to be rapidly attached to and removed from the muzzle end portion of a firearm barrel without requiring any modification to the firearm barrel. The sight mount has provisions for not marring the finish of the firearm barrel. Both the sight and the mount are made from light weight materials including plastic lenses in the sight and their weights are strictly controlled. The sight and mount increase the ability of the shooter to accurately and rapidly sight the firearm at both moving and stationary targets. A wide variety of reticles can be used such as those that are externally illuminated and self illuminating.

Abstract: A pistol grip recoil system for a shotgun or rifle and it has a pistol grip recoil assembly having a recoil base member and a pistol grip. The recoil base member is detachably secured to the rear end of the receiver of the firearm and it has an inverted T-shaped rail formed on its bottom wall. This inverted T-shaped rail is captured within and slides in an inverted T-shaped groove in the top end of the pistol grip. A recess formed in the front wall of the pistol grip adjacent its top end allows the trigger guard of the firearm to travel rearwardly with respect to the pistol grip when the firearm is fired. Various embodiments utilize springs to return the recoil base member forwardly to its static position after dissipating the recoil of the firearm resulting from its being fired.

Abstract: Low toxicity shot or pellets for shotgun cartridges or the like comprises finely divided metallic particles, preferably a mixture of finely divided molybdenum and tungsten particles in a polymer matrix. The resulting pellets have a high density and are much less prone to damage the barrels of guns from which they are fired than prior suggested alternatives to lead shot. If desired, friction between the pellets and gun barrels may be further reduced by incorporating a lubricant, such as molybdenum sulphide or graphite in the polymer matrix.

Abstract: A trigger assembly which allows for recocking a semi-automatic firearm while the trigger is still depressed through a continuous linkage assembly.

Abstract: A portable shooter's bench which includes a seat carried by a pivotable leg assembly and from which assembly a firearm support rest is adjustably mounted. In the preferred embodiment, the seat functions as a carrying handle and the bench automatically folds when lifted to carry.

Abstract: A shooting stick for supporting a hand-held pistol, includes a post, one end of which is adapted to touch the ground, and the other end is adapted to support the barrel of a pistol. The post is adjustable in length so that the height of the pistol-supporting end above the ground can be adjusted to accommodate the stature of the user of the pistol. A shelf is slidably supported near the upper end of the post in such a way that the butt of a pistol resting on the shelf can be properly positioned in the upper-supporting end of the post. The shelf is pivotally connected to the sliding support, and the post can consist of two pieces slidably interconnected so that the arrangement of shelf and the post parts can be collapsed so as to occupy a minimum space.

Abstract: An apparatus for producing an audible alarm signal upon the handling of a firearm is provided comprising a transmitter unit adapted for connection to the firearm and producing a non-audible signal when the firearm is handled and a discrete receiver unit which may be positioned at a location remote from the transmitter unit for receiving the non-audible signal and producing an audible alarm signal when the protected firearm is handled. The transmitter unit may be adapted to be received into the chamber of the firearm to be protected or it may be adapted for connection to the exterior of the firearm to be protected.

Abstract: Our integral user configurable sniper rifle stock comprises a wide forearm and a relatively narrow carry portion extending rearwardly from the forearm. An action mounting portion extends rearwardly from the carry portion. An angled relatively vertical, stippled grip extends rearwardly and downwardly from the receiver portion. An open rear stock portion extends rearwardly from the grip. The carry portion is narrower and thinner than the forearm. The action mounting, grip and rear portions are generally as wide as the carry portion. The forearm comprises a forend having an angled base and a flat serrated base portion extending rearwardly from the forend. A "T" channel rail is disposed within the angled base to mount a bipod. The folded legs of a bipod lie along the barrel. The grip defines a weight receptive cavity. A trigger guard extends from the receiver portion to the grip. The rear stock portion comprises upper and lower braces with a butt extending vertically between rear extents of the braces.

Abstract: Radiation-curable compositions containing monoalkyl or mono-aralkyl ether di-acrylates or di-methacrylates of particular ethoxylated and/or propoxylated polyols of formulae I and II have been developed. These polyol derivatives substituted with hydrophobic ether functionalities constitute UV-curable diluents that can be isolated in excellent yields with minimal losses during the manufacturing process.

Abstract: A process according to which filaments are embedded in a thermoplastic substance. The filaments pass through a chamber which is filled with a thermoplastic substance under pressure and made viscous by heating and the filaments run over a number of return members, thus having the effect of embedding the filaments in a matrix consisting of the thermoplastic. On leaving the chamber, the filaments pass through at least one die with the matrix in which they are embedded. The pseudo monofilament thus formed is subjected to a twist and is coated with a sheath of wear-resistant thermoplastic substance.

Abstract: A method is provided for manufacturing a chemical mixture, such as a gasoline blend, which conforms to a set of regulations set by an outside public agency. The invention is directed to a set of regulations which require the manufacturer to prepare a master specification which sets control limits on the chemical characteristics of the chemical mixture and require that the master specification conform to a set of controlling criteria which are dependent upon such control limits--such as predicted exhaust pollution emissions from the burning of the subject gasoline blend.
