    摘要: An ergonomic seam ripper includes: (a) an elongated haft with a bulged profile having a larger cross-section about its medial portion than cross-section at a palm end of the haft, the cross-section about the medial portion of the haft also being larger than a cross-section at a thumb grip end of the haft, wherein the palm end of the haft has an outer surface of generally planar structure and the haft is further characterized by a mounting portion at the thumb grip end of the haft; (b) a gripping member secured to the mounting portion of the haft made of a resilient rubbery material with a plurality of gripping ribs extending thereabout, wherein the gripping ribs are spread relatively close together at an upper portion thereof and relatively further apart at a lower portion thereof; and (c) a U-shaped cutting blade with a tapered projection and balled projection, as well as a shaft, wherein the shaft of the blade is secured to the haft such that the tapered projection is aligned with the upper portion of the gripping member and the balled projection is aligned with the lower portion of the gripping member.

    摘要: A fire suppression system according to an embodiment of the present invention comprises: a detection unit for detecting a particular change due to a fire and transmitting a particular change value as a measurement value; a fire extinguishing unit for spraying a fire extinguishing substance; a control unit for receiving the measurement signal and transmitting an execution signal to the fire extinguishing unit; and a management unit enabling a user or a manager to confirm whether or not there is a fire, and for remotely, operating the fire extinguishing unit, wherein the control unit transmits a notification signal to the management unit only when a measured measurement data value exceeds a threshold value, and transmits the execution signal only when an operation command is received from the management unit, thereby enhancing convenience and safety and reducing the initial cost.

    摘要: The present invention relates to a gas extinguishing system for a predefined protected area, particularly small-parts storage systems, wherein the gas extinguishing system comprises an inert gas source and a diffuser system fluidly connected to the inert gas source by a tubing system. The diffuser system comprises a diffuser tube having a plurality of drill holes provided in the surface of the diffuser tube and a pressure reducer allocated to the diffuser tube. In order to be able to achieve non-interactiveness with respect to the diffuser system from the standpoint of the design of the gas extinguishing system, the inventive provides for designing the diffuser system such that a primary baffle pressure measured in absolute bar is at least twice as high as the internal pressure of the diffuser tube during the flooding period dimensioned for the protected area and that the internal pressure of the diffuser tube during the dimensioned flooding period is at a maximum of 2 bar absolute.

    摘要: A method for controlling an inerting system designed to inject a flow of inert gas into a fuel tank of an aircraft during a mission. The method includes: determining a value of a parameter of the mission of the aircraft at a given moment; determining the ratio between the determined value of the mission parameter and a value at the given moment of an equivalent parameter of a standard mission profile, and deducing a weight coefficient therefrom; using the weight coefficient to weight a value of the inert gas flow rate recommended by the standard mission profile for the value of the equivalent parameter at the given moment so that an appropriate inert gas flow rate to be injected is determined for the needs of the mission at the given moment; and commanding the inerting system to inject the inert gas flow rate determined at the given moment.
