Abstract: A muzzle loader rod assembly of the present invention is an elongate sectioned rod, preferably made of brass is disclosed. At one remote end of the rod, a slide telescopingly surrounds the rod and is removably secured thereto by means of a set screw or similar fastener to prevent rattling when the product is in the field and to further secure the parts together. A wide variety of tools can be secured to the end of the ramrod accessory tamper portion and coupler including bullet removers, patch removers, tampers, cleaning tools, brushes, and the like. In use for bullet removal, the bullet removal member is secured to one end of the accessory tamper end of the rod, and then tapped in place by dropping the reciprocating slide. No particular real strength is required to do this. When the bullet extractor is removed, the accessory coupler becomes a tamper. The bullet tamped into the powder with an empirically determined number of strokes of the dropped slide which imparts uniformity of tamping to each charge.

Abstract: A sighting device in the form of a fiber optic front sight has a frame which mates with a vent rib of a weapon. The frame defines a hole which fits over a front bead sight on the shotgun. A locking screw threadingly received in an upstanding boss on the frame is turned such that the locking screw engages the bead sight to secure the sighting device to the shotgun. A fiber optic element is secured to the frame and the mating of the frame with the vent rib aligns the fiber optic element such that one end faces the stock end of the weapon. The fiber optic element absorbs available light and emits this light through the ends of the element. Another embodiment of the sighting device utilizes a bolt to secure the sighting device to the shotgun by threadingly engaging the threaded bore used to mount the front bead sight once the front bead sight has been removed. An additional embodiment utilizes a front sight with one fiber optic element and a rear sight with a pair of fiber optic elements.

Abstract: A tamper resistant trigger blocking device for weapons having a trigger guard featuring a pair of blocking members that cover the opposite sides of the trigger guard preventing entry into the trigger area. The two blocking members are clamped together by a pair of oppositely disposed combination locks each of which has a plunger in the other blocking member that is grasped by the combination locks. Movement of the blocking members in the plane of the trigger guard is minimized by a plurality of indexible rods in one of the blocking members that are engageable with both sides of the trigger guard to prevent that movement. The user adjusts the positions of these rods to fit the user's trigger guard size and shape.

Abstract: Improved rail adapter systems which enable firearms, including M16 type rifles and carbines, without any changes to the weapon except the handguard, to support accessory devices effectively even under combat conditions are provided via the invention by modification of the top semicylinderical part of the rifle's handguard attachment to include an elongated leaf spring arrangement in the front end and a unique rear clamp arrangement at the back end thereof so the leaf spring and rear clamp combination operate to compensate for thermal dimensional changes and combat abuse problems to maintain proper alignment of accessory devices attached to the weapon.

Abstract: A gas-pressure loading arrangement for a self-loading rifle includes a gas cylinder fluidly connected to the bore of the rifle barrel and a gas piston received in the gas cylinder to define a gas chamber. The gas piston has piston ring members seated thereon in engagement with the inner surface of the gas cylinder under tension. The piston ring members allow the gas piston to be loosely received in the gas cylinder while preventing gas leakage around the piston. The piston ring members also scrape gas deposits off the inner wall of the gas cylinder during piston movement so that the inner wall remains clean.

Abstract: An externally adjustable slide trigger assembly which is a drop-in replacement for existing conventional slide triggers. No drilling/tapping or other handgun modifications are required. The variable adjustment range provided allows the handgun owner to change trigger-pull characteristics from a stock trigger-pull weight to a low competition trigger-pull weight in the field. Trigger slack is completely eliminated at or near competition trigger-pull weights.

Abstract: A loading lever assembly for a hand-operated firearm has a loading lever which can be pivoted from a released position in which it lies in the longitudinal direction of the weapon to an end-of-swing position on either side of the weapon. The lever is pivotally connected to a mounting strip on the breech block carrier by means of an oblong slot formed in an end of the loading lever and a pivot pin on the mounting strip. The oblong slot allows the lever to be moved from an end-of-swing position to an operation position in which the loading lever engages two end stops on the mounting strip to prevent the lever from swinging forward or rearward. A spring-loaded cam arrangement provides the restoring force for returning the lever to the released position from the end-of-swing positions.

Abstract: The present invention is a firearm rest having an elongate shaft with a Y shaped cradle such that the branches of the cradle are notched on their periphery, and there is a vertical hole located at a base of one of the branches. The present invention includes a camouflage screen that has a face screen portion and a body screen portion. The face screen portion of the camouflage screen is rectangular in shape and made from two pieces of material, thereby forming a pocket with an opening at its top side. The face screen portion attaches to the branches of the Y shaped cradle of a firearm rest. The body screen portion of the camouflage screen is trapezoidal in shape and attaches to the bottom of the face screen portion. The bottom of the body screen portion can be attached to the ground with stakes to provide broader coverage to a hunter. The present invention also includes an umbrella, the shaft of which fits through the vertical hole located in the Y shaped cradle.

Abstract: An apparatus helps a user steadily hold a pointable device, such as a camera, a telescope, or a gun. It includes an arm rest having upper and lower portions, respectively, for supporting an upper arm from below and for restricting rotation of a lower arm bent at the elbow. The upper and lower arm holding portions each can press against a user's arm from enough directions to retard motion of the arm perpendicular to its length. The upper and lower portions can include cylindrical inner surfaces angled to bend an arm at least sixty degrees at the elbow. A support holds the arm rest from below. The support can include a rigid elongated member. In some embodiments, this member reaches to the ground. In many others, it rests against a user's hip and has a lower end designed to be supported by a pocket, belt, or Velcro pad on the user's hip.

Abstract: An isokinetic sampling system and method of operation assures the taking of more valid data over a long period by automated isokinetic sampling of flue gases in the stack for a stationary combustor. Sample air is extracted from the flue gases by a sampling probe having a sampling nozzle of a precise inner diameter, a thermocouple to measure the air temperature in the stack, and a pitot tube that gives readings representative of differential pressure across sampling nozzle. A separate transducer senses absolute pressure of the flue gases. Temperatures, absolute pressures and differential pressures of the flue gases are measured and representations of the temperatures, absolute pressures and differential pressures are fed to a micromanometer which feeds signals representative of these representations to a computer that generates responsive control signals for a mass flow controller.

Abstract: A leak detector and shut-off apparatus shuts off hydraulic fluid downstream o prevent the hazards attendant hydraulic failure such as loss of fluid and fire. A first sensor is coupled to a supply line for hydraulic fluid to produce pressure differential force F.sub.s, which is representative of the flow of hydraulic fluid. A second sensor is coupled to a return line for hydraulic fluid to produce pressure differential force F.sub.r that is representative of flow of hydraulic fluid. A compensator creates representation F.sub.c of the rate of accumulation of hydraulic fluid in the hydraulic circuit downstream of the device and a safety margin. A shutoff mechanism is connected to the first and second sensors and the compensator to shut off the supply and return lines when F.sub.s is greater than the sum of F.sub.r and F.sub.c.
