Patent number: 11449646Abstract: 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.Type: GrantFiled: November 1, 2019Date of Patent: September 20, 2022Assignee: HEXAGON MANUFACTURING INTELLIGENCE CANADA LIMITEDInventors: Victor Apanovitch, Stefan Martin Walter Huhn, Yongguo Wu, Derek Edward George Peeling, Dong Zhao

Patent number: 11424505Abstract: 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.Type: GrantFiled: July 5, 2018Date of Patent: August 23, 2022Assignee: CHARGER INDUSTRIES CANADA LIMITED PARTNERSHIPInventors: Quentin Pare, Carl Brown

Patent number: 11373771Abstract: 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.Type: GrantFiled: August 5, 2020Date of Patent: June 28, 2022Assignee: ATOMIC ENERGY OF CANADA LIMITEDInventors: David Bruce Rhodes, James Edward Allen Mcgregor
