Patent number: 8776693Abstract: An apparatus and method for dispensing incendiary projectiles is provided. The apparatus includes an injector for injecting the projectiles with a reactant at a dispensing rate, and a controller operable to control the dispensing rate. The controller is operable to control solenoids of a dispenser gate and a shuttle motor, and to prevent jam conditions of the apparatus. The apparatus can detect and automatically correct jam conditions that do occur. The apparatus can count the number of incendiary projectiles dispensed during a current operation and during the lifetime of the apparatus. The apparatus is dimensioned to minimize the number of incendiary projectiles purged from the apparatus after an operator has indicated to stop dispensing.Type: GrantFiled: February 27, 2008Date of Patent: July 15, 2014Assignee: Donmark Holdings Inc.Inventors: Mark D. Toeckes, Earl D. Trautman, Edward S. Vanderploeg

Patent number: 8453753Abstract: Firefighting bucket (11) suspended from an aircraft by lines (15), has open top (12A) and a valve at base (13). The valve is attachable to the aircraft by remotely actuatable line (16) and independent movement of lines (15-16) may utilize the weight of the water to facilitate opening and closing of the valve. Dynamic sensing of a bucket attribute, e.g. weight, enables bucket (11) to be filled or discharged by a pre-determined volume by the pilot. Chemical fire retardant may be added by entraining it with water discharging from the valve.Type: GrantFiled: March 29, 2010Date of Patent: June 4, 2013Assignee: Donmark Holdings Inc.Inventors: Geoff Hall, Mark Robertson

Patent number: 8316750Abstract: An apparatus and method for launching incendiary projectiles is provided. The apparatus includes a support adapted to being mounted to a vehicle, a pneumatic launcher connected to the support and operable to launch a projectile that has been delivered to the launcher, a gas delivery system operable to deliver a volume of pressurized gas to the launcher for launching the projectile, a projectile delivery system operable to deliver projectiles to the launcher, an injector cooperating operable to receive projectiles from the projectile delivery system and to inject the projectiles with an amount of reactant suitable to produce a delayed exothermic reaction with the incendiary material to prime the projectile, and thereafter convey the primed projectile to the launcher; and a controller operable to operable to regulate the launching of the projectiles.Type: GrantFiled: May 11, 2009Date of Patent: November 27, 2012Assignee: Donmark Holdings Inc.Inventors: Mark Toeckes, Earl Trautman, Cyril T.
