Abstract: A reuseable war game device launches paint-balls or liquid colorant or both simultaneously, and can be aimed and fired while hand-held, can be concealed and aimed but remotely triggered, is easy to dismantle and repair under field conditions, is durable enough to withstand all field conditions, and is concealable, compact and easily portable. The device comprises a launch housing that includes a launch barrel joined to a rotatable muzzle assembly that is fixed on a target; a chamber housing that includes a charge chamber which receives and stores a charge; a hammer chamber that includes a retractable hammer that when released from a cocked position is thrust toward the charge chamber; a trigger that is drawn to retract the hammer to the cocked position; and, a check valve located between the launch barrel and the charge chamber that permits flow only from the charge chamber to the launch housing.

Abstract: An automatic auxiliary condensate drain for an automatic dry-pipe type fire protection sprinkler system, wherein condensation which forms within the sprinkler system due to changes in temperature is drained from the condensate reservoir at the direction of a programmable controller. The programmable controller coordinates the opening and closing of inlet and outlet valves so that accumulated condensate is drained from the system, yet the pressurized gas located in the sprinkler system is not allowed to escape. Actuators operate the inlet and outlet valves in response to signals from the programmable controller.
