Publication number: 20220364559Abstract: A mud motor includes a rotor and a stator. Drilling fluid received by cavities of the mud motor drives the rotor to rotate within the stator. The rotor includes one or more rotor lobes extending helically and defining a rotor pitch. The stator includes two or more stator lobes extending helically and defining a stator pitch. The rotor and the stator together define a tapered profile of the mud motor that varies proceeding from a top end of the mud motor to a bottom end of the mud motor. At least one of the rotor pitch or the stator pitch vary as proceeding from the top end of the mud motor to the bottom end of the mud motor.Type: ApplicationFiled: May 14, 2020Publication date: November 17, 2022Inventors: Anton Kolyshkin, Maxim Pushkarev, Samba Ba, Li Guo, Robert Little, Geoffrey Charles Downton

Patent number: 11231177Abstract: A fireplace system can comprise a firebox and a heat exchanger. The heat exchanger may be in fluid communication with ambient air and may comprise an inlet configured to draw air into the front of the heat exchanger. Operation of a fireplace system comprising a heat exchanger may produce airflow through the heat exchanger by natural convection. The airflow through the heat exchanger may reduce heat transmission from the firebox and the fireplace system.Type: GrantFiled: April 23, 2019Date of Patent: January 25, 2022Assignee: FPI FIREPLACE PRODUCTS INTERNATIONAL LTD.Inventors: Robert Little, Julian Mills

Publication number: 20200081962Abstract: A virtual library of content is provided that makes it appear that the content is all of a supported file type for a particular client accessing the virtual library. When the virtual library is displayed at a client device, the content appears as if it is available in the appropriate format for the client device irrespective of the content's actual format. Content selected from a content library interface for the virtual library is provided in the appropriate format for the client device through the automatic invoking of a content access service. The content access service can determine the appropriate consumption format for the client device and convert to a supported file format any content that is in a non-supported format before providing the content to the client device.Type: ApplicationFiled: November 11, 2019Publication date: March 12, 2020Inventors: Robert A.
