Abstract: An apparatus for reducing vibration includes: a damping assembly configured to be fixedly attached to a downhole component, the downhole component configured to rotate within a borehole in an earth formation, the damping assembly having a damping frequency that is tuned relative to a selected natural vibration frequency of the rotating downhole component to reduce vibration due to component rotation.

Abstract: A method for presenting drilling information includes presenting a display including a graph having a first axis and a second axis. The first axis represents a rate of penetration (ROP) of a drill bit into a borehole and the second axis representing a mechanical specific energy (MSE) of a drilling system that includes the drill bit. The method also includes plotting time based or foot based data with a computing device for one or more drilling runs on the graph and overlaying the graph with lines of constant power.

Furthermore, the invention describes a method for virucidal disinfection of skin.

Abstract: A method of predicting behavior of a drilling assembly includes: generating a mathematical representation of a geometry of each of a plurality of components of a drilling assembly, the plurality of components including a plurality of cutters and one or more additional components configured to at least one of: support the plurality of cutters and operably connect the plurality of cutters to the drill string, the one or more additional components including a drill bit crown; simulating one or more operating conditions incident on the drilling assembly representation, and simulating an interaction between the plurality of components and an earth formation; and predicting physical responses of the drilling assembly representation to the one or more conditions.

Abstract: A method of operating a drill string includes receiving signals indicative of rotation of a bottom hole assembly (BHA) of the drill string; receiving signals indicative of the torque experience by the BHA; determining from the received signals an average slipping torque and a maximum sticking torque; determining a friction ratio based on the maximum sticking torque and the average slipping torque; and generating an indication that the friction ratio exceeds a limit.

Abstract: The invention relates to a virucidal composition comprising based on the composition from 80 to 99 wt-% of a C2-C4 monoalcohol or a mixture thereof, from 0.1 to lower 2 wt-% of an organic acid, from 0.1 to 1 wt-% of an alkoxylated monoglyceride and/or alkoxylated diglyceride, wherein the pH value of the composition is from pH 3.3 to 5 and the remainder up to 100 wt-% is water. The invention further describes a method of inactivating viruses, and a product comprising the virucidal composition and means for applying it.

Abstract: A system and method for tracking and managing maintenance of serviceable items based on unique identification labeling affixed to the items is disclosed. The serviceable items are described as filters within a common environment that require routine maintenance to adhere to certain expectations relative to the operability of the items. Such operability may relate to any type of filtering of contaminants from a liquid or gaseous substance that flows through the filters. A unique identifier (ID) label is affixed to each filter. The unique ID label represents a unique filter ID that uniquely identifies the filter relative to all other filters in the common environment. A handheld computing device communicatively connected to a local computer reads the unique ID label of each filter following maintenance of the filter to track maintenance of the filters over time.

Abstract: The invention relates to a powdered disinfectant containing a peroxide, an acylating agent and nonionic surfactants and to the use of this disinfectant for disinfecting surfaces and instruments, particularly in the medical field.

Abstract: The present invention relates to a two-part antimicrobial system having an amine part and an oxygen part, where the two parts are mixed prior to use to form an improved antimicrobial composition. Also disclosed are antimicrobial compositions and methods of making, and using the antimicrobial compositions.

Abstract: An airbag arrangement for a motor vehicle includes an inflatable element having two opposed side faces. Mounting straps extend from each side face to mounting points provided in the roof of the motor vehicle. The mounting points are spaced apart transversely. When inflated the inflatable element extends down from the roof of the motor vehicle to be located between heads of the occupants of two adjacent seats. Part of the inflatable element between the straps is in contact with the roof and the straps associated with each side face are tensioned so that the airbag is held firmly in position.
