  • Patent number: 11980669
    Abstract: An antibody production process in mammalian cells in which engineered unpaired cysteine residues are post-translationally modified and capped with particular chemical entities, which capped antibodies are well suited to further site-specific conjugation steps to form antibody-drug conjugates (ADCs) or protein drug conjugates; ADCs produced using these capped antibodies including in particular ADCs formed by the selective reduction of the capped antibodies' cysteine residues, and ADCs formed using chemical handles such as aldehyde/azide/alkyne biorthogonal groups, which permit additional drug conjugation chemistry; and uncapped antibodies produced by cells in low cysteine, cysteine and glutathione media, and ADCs produced via direct conjugation to these uncapped antibodies.

  • Patent number: 11970180
    Abstract: Vehicles may have autonomous capabilities that permit the vehicle to navigate according to varying levels of participation by a human operator. A human operator may be associated with a driving capability profile and the environment surrounding a vehicle may be associated with an environmental risk profile. A vehicle, or another party in communication with a vehicle, may determine whether, based on the human operator's driving capability profile and the environmental risk profile, it is likely that the vehicle will be navigated more safely if there is a change to the vehicle's autonomous capabilities and a corresponding change to the human operator's driving responsibilities. If it is determined that a change in autonomous vehicle capability is likely to increase safe navigation of the vehicle, an insurer may offer an insurance premium cost reduction if the human operator agrees to the proposed change in autonomous capabilities.

  • Patent number: 9416894
    Abstract: A system for verifiably locking a first cylindrical component to a second cylindrical component in a safe and secure manner. The system provides a visible indication when the first component and second component are fully and effectively secured. The first cylindrical component comprises a lock cylinder fixedly attached to the first cylindrical component. The lock cylinder comprises a lock piston. The second cylindrical component comprises a channel with a guide region and a lock region. The visible portion of the lock piston provides an indication of whether or not the lock piston is secured in the lock region of the channel. The system is also capable of being operated from a control panel to operate the locks, receive signals from sensors, and to display the lock status of the system. The system offers redundant verifications to enhance safety in operating environments.

  • Patent number: 9004175
    Abstract: A method and system for rapid containment and intervention of a subsea well blowout that can be performed in a rapid and efficient manner, where containment will minimize the damage to the environment and assets. The method can include disconnecting a riser from a subsea well after a blowout has occurred and moving the mobile offshore drilling unit away from the subsea well. Connecting a lower marine riser package with a blowout preventer, and diverting the well. The pressure and flow of the well fluid can be observed. At least of portion of the diversion path can be closed off and kill fluid and or cement pumped to the subsea well to kill and control the well.

  • Patent number: 7718811
    Abstract: A process for reacting in a fluid bed reactor at least one oxidisable reactant with molecular oxygen in the presence of a catalytically active fluidised bed of solid particles. In the process a molecular oxygen-containing gas having an oxygen concentration greater than that of air is introduced into the fluidised bed whilst the fluidised bed is maintained in a turbulent regime. The process is suitable for oxidation, ammoxidation and carboxylation processes, including the production of maleic anhydride, acrylonitrile, ethylene, acetic acid and vinyl acetate.
