Patent number: 10603533Abstract: Noise and room air overpressure on discharge of a gas extinguisher system is reduced. During the discharge, an extinguishing fluid is conveyed from a pressurized container via a container valve and line system to an extinguishing nozzle. At the beginning of the discharge the extinguishing fluid is predominantly present in the line system in liquid phase and after discharge it assumes a predominantly gaseous phase. In a phase transition period, which is accompanied by a significant reduction in the extinguishing fluid mass flow and a significant increase in the noise and the room air pressure, the mass flow is then reduced or stopped. Due to the reduction of the mass flow, the sound level of the noise arising is advantageously reduced to a value of a maximum of 100 dB and the room air pressure to an overpressure value ranging from 200 to 1000 Pa.Type: GrantFiled: November 16, 2017Date of Patent: March 31, 2020Assignee: Siemens Schweiz AGInventors: Gerd Huelsen, Benno Rupp

Patent number: 10583448Abstract: In an example, an electrostatic spray module includes a base unit formed of a sturdy, rigid, liquid impermeable, electrically insulative material and a cover formed of a sturdy, rigid, liquid impermeable, electrically insulative material and sized for covering the base unit. The base unit and the cover configured for mating engagement together so as to form a liquid impermeable, electrically insulative, protective enclosure when the module is in a closed state to keep the internal components clean and dry and prevents high voltage shorting and prevents leakage of current by inhibiting a high voltage from establishing a return path to ground. The spray module includes a quick access latch and gasket system—with no tools required to open for maintenance. The module includes integral place holders for components including air supply manifold and variable voltage supply to provide a selectable high voltage level to accommodate various spraying application.Type: GrantFiled: June 20, 2017Date of Patent: March 10, 2020Assignee: Progressive Grower Technologies, Inc.Inventor: William J.

Patent number: 10518117Abstract: A new firefighting nozzle has a series of moveable vanes that extend inwardly from a peripheral wall of a base. The inner side of the vanes extends between ? and ? of the diameter of the central channel. The vanes rotate between a linear position, in which the vanes are generally parallel to the direction of the channel, and a vortex position, in which the vanes are significantly angled with respect to the direction of the channel. In the linear position, smooth bore linear flow is produced. In the vortex position, any of a range of fog patterns are produced. An externally mounted controller connects to the vanes and enables a firefighter to change the shape of the nozzle's spray without interrupting the flow. The controller and base have a series of pins that slide in a spiral groove and cause the shaper to move axially with respect to the base when the shaper is rotated about the base. Radial stems that ride in a circumferential slot translate that axial movement into rotation of the vanes.Type: GrantFiled: October 6, 2016Date of Patent: December 31, 2019Assignee: TASK FORCE TIPS LLCInventors: Robert W. Steingass, William D. Walker, Erin L. Roark, John L. Christos, Kimberly A. Hale, Stewart McMillan
