Abstract: A fluid dispensing anti-burglar booby trap device is disclosed which discharges a fluid, containing a chemical such as tear gas, from a pressurized container into an area to be protected when an intruder opens a door or window to enter an unauthorized area with which the device is associated. The pressurized container is moveably mounted in the anti-burglar device between an actuatable position and an inactuatable position. When the pressurized container is in the actuatable position, opening a door or a window will cause the device to discharge fluid from the pressurized container.

Abstract: An electroluminescent display device includes at least two elongated, conductive contacts substantially adjacent to and spaced from each other with at least two substantially coextensive ends. A light-emitting element is electrically coupled between the coextensive ends. An elongated insulating base is formed about and between the contacts with their elongated outer edges extending beyond the elongated sides of the base. The base extends substantially the entire length of the outer edges of the contacts and is substantially integral between such contacts.The device is fabricated in a lead frame environment, wherein the light-emitting element is bonded to a lead frame. A lens is formed over the light-emitting element. The contacts for the device, which may be slidably engageable, are formed from the lead frame. The base is formed contiguous to the lens and over the lead frame to embed the contacts within the base with edges of the contacts extending laterally beyond the surface of the base.

Abstract: A fluid dispensing anti-burglar device is disclosed in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder forces entry into an area with which the device is associated. The anti-burglar device employs an element to delay the release of the chemical irritant. It also has provisions for resetting the trigger and recocking the spring associated with the device if the device is accidentally triggered.

Abstract: A chemical dispensing anti-burglary device is described in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder opens a window or opens a door or enters an unauthorized area with which the device is associated. The anti-burglary device employs a spring biased pressurized container for discharging a chemical through a passageway and nozzle. A mechanical trigger for releasably retaining the pressurized container in a cocked position, an improved mechanical and electromechanical trigger to release the chemical, and a built in safety to deactivate the device which makes it virtually impossible to accidentally discharge the device are described.

Abstract: A chemical dispensing anti-burglary device is disclosed in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder opens a window or a door or forces open a window or a door to enter a private or unauthorized area with which the device is associated. The anti-burglary device employs a spring biased firing member for discharging a chemical irritant from a pressurized container. An improved means for releasably retaining the firing member in a cocked position and improved mechanical and electromechanical means for releasing the chemical irritant are described.
