The invention relates to a hand casting type simulation bomb for training and belongs to the field of military teaching training tools. The hand casting type simulation bomb for training comprises a simulation anti-riot bomb and a simulation hand grenade, wherein the simulation anti-riot bomb comprises a shape simulation shell, a secure structure, a delayed explosion starting mechanism and a blank cartridge, and the simulation hand grenade is composed of a shape simulation shell, a handle, a pull wire, a delayed explosion starting mechanism and a blank cartridge. The hand casting type simulation bomb for training has the advantages that live ammunition explosion starting motions and explosion starting delaying can be simulated, and the sound production, smoke production and misoperation alarming functions are achieved; furthermore, the hand casting type simulation bomb does not have the live ammunition demage effect, and the performance of the simulation anti-riot bomb (hand grenade) for teaching training is safe and reliable. The hand casting type simulation bomb for training has important application value and practical significance on ensuring military police unit training safety, improving training benefits, reducing training consumption and shortening a fighting capacity generating cycle.

A blank cartridge and mated blank chamber for simulated firearms incapable of discharging projectiles. The blank cartridge has a case with a cartridge base, a case wall, a cartridge shoulder forming a neck, and a nose enclosing the blank cartridge. The blank cartridge nose provides more reliable feeding from magazines of simulated firearms. The blank cartridge dimensions render it inoperable with ammunition chambers of actual projectile-discharging firearms. The blank chamber dimensions render it inoperable with ammunition cartridges. Upon discharge the blank cartridge and chamber release exhaust gases in a forward direction, creating realistic visual and auditory effects.

A simulated firearm for discharging a blank cartridge and generating a realistic flash and report from the muzzle. The simulated firearm of the present invention prevents the discharge of lethal cartridges or projectiles. The simulated firearm has a chamber 65. The chamber 65 is reversed so that the entrance to the chamber 65 faces the forward section of the simulated firearm. A blank cartridge is loaded into the chamber 65. The blank cartridge is safely discharged from the reversed chamber.

An automobile safety glass breaker tool is held against an automobile safety glass window and fired to break the window. The tool is armed by sliding a firing pin piston to the rear against a spring and fired by releasing the firing pin piston. The firing pin piston hits a 0.22 blank cartridge to fire the blank cartridge. The blank cartridge drives a striker piston forward, and a striker point on the striker piston impacts and shatters the automobile safety glass window. The striker point is limited to reach about 0.06 inches forward and out of the tool to prevent injury to a user.

A target device is usable with a simulation system which includes a weapon simulator having a trigger, a chamber for firing a blank cartridge in response to the trigger, and a transmitter arranged to emit a light signal defining one or more activation codes of prescribed duration in response to the trigger. The target device includes a sensor array of photodiodes and a processor receiving output signals from the photodiodes. The processor determines that the sensor array has been hit by the weapon simulator in response to a first portion of one activation code being received by one of the photodiodes and at least one second portion of the same activation code being received by the same or a different one of the photodiodes when the first portion and the at least one second portion correspond to an entirety of one activation code within the respective prescribed duration.

Devices and methods for altering a firearm to prevent firing of rounds of a first size while allowing the firing of rounds of a smaller, second size are provided. In one embodiment, a barrel safety device prevents a live round from fully chambering in a firearm, while allowing a blank to be chambered and fired from the firearm. The barrel safety device includes a muzzle block, a rod, and a tip in one embodiment. The rod and the tip can be sized so as obstruct a portion of the barrel and / or the bullet chamber of the firearm, such that a round having a first length, such as a live round, contacts the tip of the barrel safety device and cannot be fully chambered. The rod and the tip can be sized so as to allow a cartridge having a second, smaller length, such as a blank cartridge, to be fully chambered without contacting the tip of the barrel safety device.

The invention relates to an electrochemical corrosion processing method for micro-column group electrodes, which belongs to the field of electrolytic processing. The method comprises the following steps: (1) using electric discharge wire cutting or micro-milling technology to manufacture a group electrode blank with multiple single electrodes; (2) using finite element method to design and manufacture the cathode of an electrochemical corrosion tool; (3) The group electrode blank is used as an electrochemical corrosion anode, immersed in the electrolyte, so that each single column on the blank is completely below the liquid level; the electrochemical corrosion cathode and anode are placed vertically and parallelly; (4) power on, and the group electrode blank is Electrochemical corrosion processing uses constant voltage processing and charge method to control the shape and processing size of group electrodes respectively. The method of the invention has the characteristics of simple processing equipment and control mode, high processing efficiency and processing quality, and low manufacturing cost.

A blank handling device is provided for receiving and firing a blank cartridge for use in a non-gun. The handling device includes a housing having a blank receiving chamber sized and configured for holding the blank during firing. The blank receiving chamber includes a first axis and a first diameter. A gas discharging passageway capable of being coupled to a barrel of a non-gun, is provided that has a second axis and a second diameter. A gas flow passageway is fluidly coupled to and extends between the blank receiving chamber and the gas flow passageway for conducting gasses discharged by the firing of the blank cartridge between the blank receiving chamber and the gas discharging passageway. The gas flow passageway has a third axis and a third diameter. The third diameter is less than the first diameter for preventing the passage through the gas flow passageway of a projectile discharged in the blank receiving chamber.

The invention discloses an electric shock bullet, aiming to provide a convenient and effective police nonlethal bullet for police and armed police. The electric shock bullet can be used in a range of several tens of meters and can be shot by the prior guns and blank cartridges to hit the non-critical parts of criminals and come over the criminals by electric shot of the high-voltage pulse emittedfrom the bullet, and the criminals can not leave permanent wound or be killed. The electric shock bullet is suitable for guns with various calibers, such as pistols and rifles. The electric shock bullet comprises a bullet shell, a tail rod, a primary battery, a high-voltage pulse generator, a negative pole electrode, a positive pole electrode and a powder on control switch, wherein the primary battery, the high-voltage pulse generator and the powder on control switch are disposed inside the bullet; the tail rod is disposed at the tail part of the bullet and capable of being inserted into the gun barrel of a gun; and the negative pole electrode and the positive pole electrode are disposed in the head part of the bullet.
