A toy water gun actuation mechanism for controlling opening of a valve with a base, a trigger, a coupling member being configured to be connected to the valve member and further comprising a movably supported blocking member with an abutment that enables to open and close the valve in a given period if the blocking member is in its blocking position and if the coupling member is in the first position, then the abutment is positioned in trajectory of the coupling member defined by a movement of the coupling member from the first position into the second position, whereas if the blocking member is in its non-blocking position, the abutment is located outside the trajectory being defined by the movement of the coupling member. Further a first elastic member is connected to the trigger and to the coupling member, wherein the potential energy being stored by the first elastic member is increased, if the trigger is moved from its released position towards its actuated position while the coupling member is maintained in its first position by the blocking member, and the trigger has a pusher dog configured to move and/or release a movement of the blocking member from the blocking position into its non-blocking position if the trigger is moved from its non-actuated position towards its actuated position.

Explosive devices may be formed from hollow members filled with explosive materials. The hollow members may be made of mating halves that are packed or loaded with explosive material prior to the mating halves being joined together. In some exemplary aspects, the hollow members are placed in fluid-filled containers such that the explosive reaction creates a wave of fluid that impacts a target. Components of the devices may be COTS items and items that may be manufacture with 3D printers.

An explosive disruptor system including a disruptor container cavity; a disruptor tube having an initiating explosive chamber extending from a disruptor tube open end to a disruptor tube shoulder and a primary explosive chamber extending from the disruptor tube shoulder to a disruptor tube bottom wall, the primary explosive chamber having a reduced internal diameter when compared to an internal diameter of the initiating explosive chamber; a container cap having a aperture formed therethrough; and a strain relief connector having a body portion with external strain relief connector body threads, the body portion being at least partially insertable through the aperture such that at least a portion of the external strain relief connector body threads extend through the aperture, the external strain relief connector body threads formed so as to interact with internal disruptor tube threads to repeatably threadedly attached the strain relief connector to the disruptor tube.

A liquid replenishing mechanism and a water gun include a housing, a conductive component, a conveying component, and a liquid storage component. The housing includes a first outer surface. The conductive component is exposed outside the first outer surface and is electrically connected with the conveying component. The conveying component defines a liquid inlet end extended to the first outer surface and communicated with an outside of the housing and a liquid outlet end. The liquid storage component includes a liquid storage cavity communicated with the liquid outlet end. The conductive component is driven by the first outer surface to contact with liquid or moved away from the liquid. The conveying component is electrically connected with a power supply through the liquid. The liquid is input through the liquid inlet end and is output to the liquid storage cavity through the liquid outlet end.

A toy water gun actuation mechanism for controlling opening of a valve with a base, a trigger, a coupling member being configured to be connected to the valve member and including a movably supported blocking member with an abutment that enables a valve to be opened and closed in a given period if the blocking member is in a blocking position and if the coupling member is in the a first position, the abutment then being positioned in trajectory of the coupling member defined by a movement of the coupling member from the first position into a second. If the blocking member is in its non-blocking position, the abutment is located outside the trajectory. A first elastic member is connected to the trigger and to the coupling member, The trigger has a pusher dog configured to move and/or release a movement of the blocking member into a non-blocking position.

A toy launcher having a telescopic barrel, a plunger element, and a compression spring that biases the plunger element against a rear wall of the telescopic barrel. When a cocking slide is moved from a forward position to a backward position, the plunger element partially compresses the compression spring against the rear wall of the telescopic barrel, while the plunger element couples to a trigger assembly. Fluid from a reservoir enters a fluid chamber formed by the plunger element and the front part of the telescopic barrel. When the cocking slide is moved from the backward position to the forward position, the rear part of the telescopic barrel fully compresses the compression spring. Fluid is expelled from the fluid chamber when the coupling between the plunger element and trigger assembly is released.

A water gun comprising a pressure tank, a nozzle, a tube and valve with a valve conduit has an increased shooting range if the pressure tank has an outlet being connected to an inlet of the tube, the tube has an outlet being connected to an inlet port of the valve conduit and an outlet port of the valve conduit is in fluid communication with the nozzle.

A propellant driven disrupter (PDD) for disrupting an explosive target, comprising: a disrupter barrel having a breech and muzzle end; a projectile liquid or gas positioned in the barrel and extending a longitudinal distance in the disrupter barrel. The projectile liquid distal end is located farthest from the disrupter barrel breech end. A jet stabilizing projectile (JSP) is at least partially positioned in the barrel and operably contacts the projectile liquid distal end. The JSP has a JSP proximal end facing toward the disrupter barrel breech end and a distal end opposed to the JSP proximal end, wherein some or all of the JSP is positioned in the barrel. The PDD may contain the JSP, with an air region between the JSP distal end and the muzzle end, or an air region in an adapter that is connected to the muzzle end. Also provided are JSP's having improved flight stability for use with liquid or air-filled disrupters and methods of disrupting a target.

A water toy comprising a foam tube having a first end, a second end and a body therebetween, an optional seat positioned on the body, a first feature attached to the first end, and a second feature attached to the second end, the first and second features being aesthetic and/or functional and/or a combination of the same.

A system for rendering safe unexploded military ordnance items found on land by use of a portable apparatus employing entrainment waterjet technology. The portable apparatus includes a tool package containing a plurality of tools designed for accessing the interior of a unexploded ordnance item. The interior of the ordnance item is accessed, and its internal contents, which it typically an energetic material, is washed-out and recovered.
