Abstract: A pneumatic launcher has a plenum chamber section, an intermediate chamber section and a launch tube section connected together in a generally linear arrangement. The plenum chamber section defines a plenum chamber that has a closed end and an open end. The intermediate chamber section has aft and forward rupture disks consecutively arranged to define an intermediate chamber. The plenum chamber is pressurized with a pressurized gas to a design plenum pressure and the intermediate chamber is pressurized with a pressurized gas to pressure that is about one-half the design plenum pressure. The intermediate chamber is then depressurizing to produce a pressure imbalance between the plenum and intermediate chambers that causes said aft and forward rupture disks to rupture. As a result, pressure equilibrium occurs between the plenum chamber and launch tube thereby discharging the fluid and projectile from the interior of the launch tube.

Abstract: An alignment device for telescopic sight mounts (101) utilizes a front alignment portion (103) and a rear alignment portion (105) installed on a firearm 405. A front bushing (109), clamped in a front mount assembly (401) of the firearm provides a precision sliding fit with a front alignment rod (107). A rear bushing (113), clamped in a rear mount assembly (403) of the firearm provides a precision sliding fit with a rear alignment rod (107). Acceptable alignment of the front and rear mount assemblies is indicated by full engagement of a male indicator portion (115) of the front alignment rod and a female indicator portion (117) of the rear alignment rod when the respective rods are slideably engaged. A bore sight engagement element (151) allows bore sighting of the mounts with the rifle bore (425).

Abstract: A pneumatic gun firing ram for firing one or more paintballs. The paintball gun includes a body defining a bore, with the bore being in communication with a valve for selectively releasing compressed gas to fire a paintball. A piston is located within the bore, and a rod is mounted within the piston for sliding movement. A hammer is mounted on an end of the rod opposite the piston, the hammer being movable between a first position and a second position relative the piston. A clamp substantially surrounds the rod at a region adjacent the hammer, and a pneumatic valve is adapted to move the pneumatic ram from a first position in the bore at a distance from the poppet valve to a second position in the bore proximate the poppet valve.

Abstract: A method of firing of arms which utilizes both action and reaction forces in the process of firing. The action force propels the projectile (14) while the opposite in direction reaction force is used with an independent freely moving inert mass (20) in which a cartridge case (18) resides. Since the movement of the inert mass (20) does not affect the position of the barrel (12) prior to the projectile (14) leaving the muzzle, the barrel (12) remains steady during firing, thus achieving very high accuracy of shooting.

Abstract: Especially in hunting, the choice of bullets has to be such that it is in keeping with the wild animals to be hunted. According to the desired effect on the target, deformation bullets or partial fragmentation bullets are used. Since both types of bullets are different, the position of the point of impact from the same weapon is different. According to the type of bullet used, the weapon must be oriented differently in relation to the target. This can be obstructive and if insufficient attention is paid, can result in misses.

Abstract: Described is an insulated probe device of adjustable axial length for delivering an electroshock stimulus to an animal. The insulated probe device includes an electrode that is positioned in contact with the animal's skin and is disposed within an electrically non-conductive housing. The housing is a two-part housing, where the two parts cooperate such that the ultimate length of the housing is adjustable. The insulated probe devise includes a mounting device that electrically and mechanically secures the insulated probe device to an electronic animal training device. The mounting device is electrically connected to the electrode by way of a conductor, which is disposed within the housing. The conductor is a metal-rubber substance that conducts electricity like a metal and stretches like rubber such that it is capable of various lengths. Consequently, the ultimate length of the insulated probe device is adjustable.

The compression member may include a fluid passage therethrough in fluid communication with the interior of the outer cylinder. The interior of the outer cylinder may be moveable between an uncocked position and a cocked position such that movement of the outer cylinder from the cocked position toward the uncocked position compresses air in the interior of the outer cylinder, with the compressed air being delivered to through the fluid passage to a toy projectile attached to the toy projectile launcher. The toy projectile launcher may also include a spring that may bias the outer cylinder from the cocked position toward the uncocked position.

Abstract: Disclosed is a device and method for externally perforating a well-bore casing. The perforating apparatus is attached to the outside of the casing itself and is conveyed along with the casing when it is inserted into the well bore. The perforation is accomplished using two groups of charges which are contained in protective pressure chambers which are arranged radially around the outside of the wellbore casing. The pressure chambers form longitudinally extending ribs which conveniently serve to center the casing within the well bore. One group of charges is aimed inward in order to perforate the casing. A second group is aimed outward in order to perforate the formation. In an alternative embodiment, only one group of bi-directional charges is provided.
