Abstract: Disclosed herein is a firearm rest chair for resting a firearm on a rest that allows the shooter to shoulder the firearm, while the weight of the shooter absorbs the recoil of the firearm. The firearm rest chair employs a rigid frame that supports a seat and a rest point for a firearm to allow the shooter's body weight to absorb the recoil of a firearm. The disclose rest point for the firearm allows the shooter the ability to shoulder the firearm.

Abstract: The current system is a method for easily attaching firearm devices to the end of a firearm. The system is used to improve the relative alignment between firearm devices and the bore of the firearm. The system solves the problem of non-uniformity when attaching devices to a firearm, by providing a uniform mounting surface. The system includes three main parts: a muzzle extender, a device, and a clamping method. The extender includes a threaded female receptor for attaching to the firearm muzzle and a clamping surface to be used with a clamping method to attach the device. The system has multiple embodiments including, built in muzzle devices, different clamping methods, and multiple devices to attach to the system.

Abstract: The current system is a method for easily adjusting the front sight post on a firearm. The system is used to aid in easier front sight post adjustments as well as maintain a uniform sight picture throughout the aiming process. The system solves the current problem of viewing two separate sight pictures when looking through a rear sight. The system also solves the problem of needing a separate tool to adjust the sight post. The system includes four critical parts, a bottom sight post tower, a top sight post tower, a front sight post and a mechanism for providing constant upward force such as a spring. The system has multiple embodiments including the use of various sight posts.

Abstract: The embodiments described are directed to a vaporizer having a housing with a vaporizing chamber formed therein. A fine mesh conductive screen is disposed inside the vaporizing chamber for generation of heat through electrical resistance. The housing includes an aperture to the vaporizing chamber and an exhaust aperture for evacuating vapors by a user.

Abstract: A work light for work or task areas which uses light-emitting diodes (LEDs) as the source of light. LED clusters are mounted on a circuit board which is located in a housing. The LED work lights may be powered by 3.6 volt, 4.8 volt, or 6.0 volt sources.

Abstract: An apparatus for controlling relative movement between two interconnected bodies includes a first end cap, a second end cap having an opening, a sleeve interconnecting the end caps to define a chamber between the sleeve and the end caps, a piston assembly including a piston rod extending through the opening of the second end cap, a piston connected to the piston rod, received in the chamber to define at least two fluid chambers on opposed sides of the piston, and a plurality of rollers carried by the piston for rolling engagement with the sleeve. A fluid flow path provides communication between the fluid chambers and provides a restricted fluid flow rate therethrough to control the rate of fluid transfer between the fluid chambers and permit fluid pressure to increase in a chamber into which the piston is being moved to provide a force on the piston opposing its movement.

Abstract: A light for use in applications requiring conventional and specialized, dimmable lighting wherein the color of the emitted light can easily be switched. The light includes fluorescent and/or LED light sources which are dimmable by a control box. The control box further allows for switching between two light sources provided in the light. The light sources may provide white light or specialized light including red or blue “invisible” light required in some military applications or UV lighting.

Abstract: A work light for work or task areas which uses light-emitting diodes (LEDs) as the source of light. LED clusters are mounted on a circuit board which is located in a housing. The LED work lights may be powered by conventional 120 or 240-volt electrical outlets, a DC generator, a battery, a battery pack, or a car adapter.

Abstract: A fluorescent work light having a cover with restraining elements for restricting the movement of the fluorescent lamp. The restraining elements are inwardly projecting integral portions of the cover and restrict the lateral, rotational and axial movement of the fluorescent lamp. The work light also includes a rotatable socket with permits the cover to be threadingly engaged to the handle while rotationally engaging the fluorescent lamp. The distal end of the cover may consist entirely of transparent material to thereby permit light to be emitted from the distal end of the cover in all outward directions. The handle is provided with a removable end cover which is interchangeable with a plurality of different end covers.

Abstract: Workpiece chucking apparatus includes a chuck body mounting a first plurality of prepositioning lock-up fingers and a second plurality of gripping fingers. The lock-up fingers are biased together radially outwardly or inwardly into engagement with a peripheral wall of a workpiece to initially locate and support the wall of the workpiece in a centered position with respect to a central axis of the chucking apparatus. An inflatable bladder flexes the remaining gripping fingers into gripping engagement with the peripheral wall to further radially support the wall in preparation for machining, without disturbing the prepositioning of the workpiece.

Abstract: A chuck for gripping workpieces to be machined has a chuck body with a workpiece support surface for supporting a workpiece to be machined. Generally radially movable centering and gripping collet fingers are concentrically supported by the chuck body. An inflatable bladder is further mounted on the chuck body in generally concentric relationship with the fingers. Control mechanism is provided for initially radially moving the centering fingers to cause them to move radially and center said workpiece, and then supplies a fluid under pressure to inflate the bladder and move the gripping fingers generally radially to fully grip the centered workpiece.

Abstract: Workpiece chucking apparatus includes a chuck body mounting a first plurality of lock-up fingers and a second plurality of gripping fingers. The lock-up fingers are individually biased radially outward into engagement with a peripheral wall of a workpiece to initially support the workpiece in a predetermined position irrespective of the eccentricity of the peripheral wall with respect to other portions of the workpiece which are first located concentrically with the chuck axis. An inflatable bladder flexes the remaining gripping fingers into gripping engagement with the peripheral wall to further radially support the wall in preparation for machining, without disturbing the prepositioning of the workpiece.
