Patent number: 4846044Abstract: A non-lethal self defense device which applies a disabling electric shock to personnel desired to be disabled employs fluid cartridges for containing an electrically conductive fluid. The fluid cartridges each have a reservoir for holding electrically conductive fluid and a nozzle through which is expelled the electrically conductive fluid during operation of the device. A compressed gas cartridge supplies the force required for expelling the electrically conductive fluid as a pair of continuous streams. The cartridges are supported by a frame whereby the nozzle portions of the two of the fluid cartridges are aimed in substantially the same direction. A displaceable linkage responsive to release of the compressed gas from the gas cartridge causes the electrically conductive fluid to be expelled. An electrification system, which may include an oscillator and coil arrangement powered by a standard battery, supplies electrical energy to the streams of electrically conductive fluid.Type: GrantFiled: January 11, 1988Date of Patent: July 11, 1989Inventor: Roy J.

Patent number: 4750641Abstract: A toy pistol capable of ejecting a continuous stream of water while simultaneously generating a sound and a flashing light. A d-c motor positioned within the toy pistol operates a pump to pump water from a water storage cartridge in order to cause water to be ejected continuously from the toy pistol. The d.c. motor also causes an eccentric cam to rotate, such rotation causing repeated stricking of a sound generating bar, which creates a sound imitating a gun. Operation of the motor additionally causes repeated opening and closing of an electrical circuit containing a light bulb positioned in the barrel of the gun, thereby creating a flashing light effect.Type: GrantFiled: September 24, 1986Date of Patent: June 14, 1988Inventor: Hun Chin-Fu
