The regulator is also provided with a chamber having an opening for communicating with a supply of a pressurised fluid for controlling operation of the regulator.

Abstract: The present invention is a computer security system and method in which the various algorithms not only do not search for or detect the presence of a steganographic or other hidden image in a data file or across data files, but also includes at least one or more combined approaches for altering and neutralizing any hidden messages without significantly detracting from the underlying integrity of the data file or files thus treated.

Abstract: Hybrid additive manufacturing methods include building a green state additive structure, wherein building the green state additive structure comprises iteratively binding together a plurality of layers of additive material using a binder, and joining the green state additive structure to a base structure to form a hybrid article.

Abstract: Systems and methods are provided for storing and restoring digital data. In some implementations, a method is provided. The method includes receiving, while a current view of an application is displayed in a user interface, a first user input requesting that a history view associated with the current view of the application be displayed, retrieve data associated with the history view, determining a presentation format for the data, and displaying the history view in response to the first user input in accordance with the presentation format, the history view including data associated with at least a first visual representation of an earlier version of the current view of the application.

Abstract: A bundled tube fuel injector includes a fuel distribution module, a tube bundle having a plurality of pre-mix tubes that extend in parallel downstream from the fuel distribution module and a support plate disposed substantially adjacent to the fuel distribution manifold. The plurality of pre-mix tubes extends through the support plate. A retention sleeve is coupled to the support plate at a first end. A second end of the retention sleeve includes a plurality of radially extending retention features that are circumferentially arranged around the second end. The bundled tube fuel injector also includes an aft plate having a retention collar. The retention collar is configured to engage with the retention features. The retention sleeve and the retention collar partially define a cartridge passage that extends through the bundled tube fuel injector.

Abstract: A bundled tube fuel injector includes a fuel plenum that is defined within the bundled tube fuel injector and a plurality of pre-mix tubes that extend downstream from the fuel plenum substantially parallel to one another. Each pre-mix tube includes an end portion and a radially extending end surface. The bundled tube fuel injector further includes a tube tip that is fixedly connected to the end portion of a corresponding pre-mix tube.

Abstract: A method for disassembling a bundled tube fuel injector includes decoupling an aft plate from a fuel distribution module of the bundled tube fuel injector, where the aft plate is disposed at a downstream end of the bundled tube fuel injector. The method also includes removing the aft plate from the bundled tube fuel injector to expose a portion of a plurality of pre-mix tubes so as to allow for inspection repair and/or replacement of one or more of the plurality of pre-mix tubes.

Abstract: A walk-behind mower that, in one embodiment, is configured in a grass catching mode, wherein a debris container is attached to the mower in a grass collecting configuration to permit the collection of grass clippings. The mower may further be configured in an alternative mode, wherein the debris container is stored on the mower in a stowed configuration. In one embodiment, the debris container may be partially or fully supported by a handle of the mower when in the stowed configuration.

Abstract: A method for repairing a bundled tube fuel injector includes removing a portion of a pre-mix tube, aligning a tube tip with the remaining portion pre-mix tube and fixedly connecting the tube tip to the pre-mix tube. The method may further include removing an aft plate and an outer shroud from the bundled tube fuel injector so as to expose the pre-mix tube.
