  • Patent number: 12312465
    Abstract: Isocyanate-reactive compositions, rigid polyurethane foam-forming compositions, rigid polyurethane foams, and methods for their production, and composite articles having a rigid polyurethane foam sandwiched between metal facer substrates. The rigid polyurethane foams are produced from an isocyanate-reactive composition comprising: (1) a polyol blend that includes an amine-initiated polyether polyol; (2) a hydrochlorofluoroolefin (“HCFO”); and (3) a catalyst that includes an arylalkyl tertiary amine, an aryl tertiary amine, or a mixture thereof. The foam can have excellent adhesion to metal substrates.

  • Patent number: 12180324
    Abstract: A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture, heating the reaction mixture to a temperature of 100° C. or greater in the absence of a solvent in bulk conditions, and mechanically stirring the reaction mixture. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.

  • Patent number: 11163850
    Abstract: According to one aspect of the present disclosure a method and technique for managing data transfer includes receiving and storing a plurality of different data patterns anticipated to be encountered by a processor unit of a data processing system corresponding to a particular application being processed. Responsive to receiving a read request for data, the requested data is read from a memory subsystem, and the read data is compared by the memory subsystem to the stored data patterns. Responsive to determining that the read data matches at least one of the stored data patterns, the memory subsystem replaces the matching read data with a pattern tag corresponding to the matching data pattern. The pattern tag is transmitted over a communication link in response to the request.

  • Publication number: 20210236183
    Abstract: The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

  • Patent number: 10927625
    Abstract: Embodiments of the present disclosure are generally related to a method and apparatus for performing operations in subterranean wellbores. More specifically, the present disclosure provides a novel downhole tractor for use in a wellbore. The tractor includes a body and a plurality of wheels. The wheels are configured to convert rotation of the body into linear motion along the wellbore. In one embodiment, the tractor is hydraulically driven. Additionally, or alternatively, the tractor may be electrically driven. Optionally, rotation of a string of pipe interconnected to the tractor drives the tractor.

  • Patent number: 10838585
    Abstract: A system configured to determine interactive elements for non-traditional computing devices is disclosed. The system receives a portion of a webpage with a first interactive element and an element identifier. The system determines that a threshold number of interactive actions are associated with a second interactive element in a data store. The threshold number of interactive actions indicates that the second interactive element is selectable to perform an action in response to an interaction by a user. The system determines that the first interactive element is similar to the second interactive element by a similarity measure. The system provides to a computer, a selectable option associated with the element identifier of the first interactive element. The selectable option is for selection by an indirect input to the computer and for causing the action associated with the first interactive element upon the selection of the selectable option.
