  • Patent number: 11474337
    Abstract: A direct view optical sighting system. In certain examples the system includes an eyepiece, an objective that directs scene light to the eyepiece, a laser rangefinder, and a laser rangefinder coupling prism that directs a laser transmit beam from the laser rangefinder to the objective and a laser return beam from the objective to the laser rangefinder. Examples of the system further include a display assembly including a reticle prism and a display coupling prism, the reticle prism being positioned along the optical path between the laser rangefinder coupling prism and the display coupling prism and having a hard reticle formed on a surface thereof. The objective can be configured to produce a first focal plane of the optical sighting system coincident with the first surface of the reticle prism. The display coupling prism is configured to direct display light toward the eyepiece.

  • Patent number: 11449646
    Abstract: A method is provided for the creation of an addendum for use in the design and production of sheet metal formed components, which method uses a sectionless approach. In a preferred approach, elevation curve (EC) lines are established relating to the component (ECc) and binder (ECb), and it is these lines which are used to design the addendum. Additional EC lines (EC1, EC2, EC3, etc.) can be added to modify or optimize the addendum design. The spaces between the EC lines are filled using various parameterized filling techniques so as to provide the addendum design. Optimization of the addendum can be achieved by modification of the various EC lines, so as to modify or control the various design parameters, in accordance with various quality or design criteria. A more rapid, and less complicated approach to addendum design is provided.

  • Patent number: 11424505
    Abstract: A battery, a battery container, and a battery pack, for use downhole in MWD operations, one or more of which incorporates lateral vibration damping. In a preferred embodiment each comprise specialized lateral vibration damping in the form of a plurality of longitudinally-extending resiliently-deformable ridges extending substantially a length of each and circumferentially spaced about an outer periphery. The resiliently-deformable ridges on the battery may be integrally formed and extend radially outwardly from a hollow resiliently-deformable sleeve, and formed of the same resiliently-deformable material of which the sleeve is comprised. The resiliently-deformable ridges on the battery container may extend radially inwardly or outwardly from a periphery thereof. Advantageously, the battery container can thus be free of potting material and thus be reusable when the batteries thereof need be replaced.

  • Patent number: 11422573
    Abstract: The present disclosure provides methods and system for controlling the operation of a fly-by-wire aircraft. One or more yaw commands are received from an operator control, and one or more actual induced rolls rates are determined based on the yaw commands. A yaw signal and a roll-countering command are sent to flight control components of the aircraft, the yaw signal to cause a yaw motion in the aircraft, and the roll-countering command to counter the actual induced rolls. A standardized roll rate command is determined based on the yaw command, and the standardized roll rate command is sent to the flight control components to cause a roll motion in the aircraft.

  • Patent number: 11373771
    Abstract: The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.

  • Publication number: 20220146194
    Abstract: Methods and systems for processing natural gas to meet gas pipeline specifications and/or recovering natural gas liquids (NGL). The natural gas is cooled and distilled such that propane and heavier components are produced as a bottoms NGL product, and inerts, methane, ethane, and other lighter portions are produced as a fuel gas grade/quality residue gas product stream. The gas can optionally be treated to remove hydrogen-sulfide and/or carbon dioxide. The NGL product can be split into a marketable propane and butane liquefied petroleum gas (LPG) liquid product and a natural gas condensate product.

  • Patent number: 11183311
    Abstract: A fuel assembly for a pressure-tube nuclear reactor includes a fuel channel assembly. The fuel channel assembly has an outer conduit and an inner conduit received within the outer conduit. The conduits define an annular fuel bundle chamber for receiving a flow of a coolant in one direction. The inner conduit includes a central flow passage for receiving a flow of the coolant in an opposite direction. A fuel bundle positioned within the fuel bundle chamber consists of fuel elements arranged to form an inner ring surrounding the inner conduit, and an outer ring surrounding the inner ring. The coolant may be light water, and geometries of the fuel assembly may be selected so moderation by the volume of coolant promotes generally uniform power distribution in the fuel elements.
