Abstract:
A vibration damping alloy has a mixed structure of martensite and austenite. The alloy steel is iron-based to which 14-22% by weight of manganese is added. The vibration damping alloy is manufactured by mixing electrolytic iron and manganese in a molten state. The molten mixture, containing 14-22% of manganese with the remainder of iron, is cast as an ingot. The ingot is homogenized at 1000.degree.-1300.degree. C. for 20-40 hours and then hot rolled at 900.degree.-1100.degree. C. for 20 minutes to 90 minutes. The ingot is cooled with air or water.
Abstract:
A power generator device includes a heavy gyro body, at least one rotation-driving device and a control unit. The heavy gyro body is coupled to a power source and an induction power generator, the power source drives the heavy gyro body to rotate so as to drive the induction power generator to produce electricity. The rotation-driving device is located at an edge of the heavy gyro body and conducting a contact or non-contact interaction with an annular part in reaction to drive the heavy gyro body to rotate about a vertical spindle. The control unit is configured for starting the rotation-driving device to accelerate the speed of the heavy gyro body when a rotation speed of the heavy gyro body is less than a first predetermined rotation speed.
Abstract:
A secured computing system and container therefor may comprise: a base for receiving a computing device; a securable first cover for substantially enclosing at least part of the computing device when the first cover is in a first position in the base; a securable second cover for preventing access to the computing device when the second cover is in a secured position, wherein access to the computing device is available when the second cover is not in the secured position. The computing device may be substantially enclosed when the first cover is in the first position in the base and the second cover is in the secured position; and one or more user features of the computing device may be accessible when the first cover is not in the first position in the base. The computing device may include a computer processor or computer peripheral.
Abstract:
The invention relates to antioxidant compositions for lubricants and organic polymers comprising a first antioxidant comprising a reaction product of p-cresol, dicyclopentadiene and isobutylene; and a second antioxidant comprising a diarylamine. The first antioxidant preferably has the structure: wherein n is 0-50, and R1 and R2 are independently hydrogen, a straight or branched C1-C30 alkyl or alkylene group optionally substituted with one or more substituents, C3-C12 cycloalkyl, C5-C12 aryl, or C6-C12 alkylaryl. The second antioxidant preferably has the formula: (R3)a—Ar1—NH—Ar2—(R4)b wherein Ar1 and Ar2 are independently aromatic hydrocarbon groups and R3 and R4 are independently hydrogen or hydrocarbyl groups having from 6 to about 100 carbon atoms and a and b are independently 0 to 3 but (a+b) is not greater than 4.
Abstract:
A lubricant composition is disclosed that comprises lubricating oil and a mixture of at least two antioxidants, the first antioxidant being a substituted diphenylamine and/or a heterocyclic amine and the second antioxidant being a substituted phenol. Also disclosed is a method of increasing the oxidation stability of a lubricating oil comprising adding thereto at least two antioxidants, the first antioxidant being a substituted diphenylamine and/or a heterocyclic amine and the second antioxidant being a substituted phenol.
Abstract:
The present invention relates to a handheld terminal capable of supporting menu selection using dragging on a touch screen and a method of controlling the handheld terminal. When one of first level menu items displayed on a touch screen is touched, one or more second level menus belonging to the touched first level menu item are displayed. When a drag to one of the second level menu items is performed, a plurality of third level menu items belonging to a menu item corresponding to a location at which the drag was performed is displayed. When a release, ending the touch, is performed, a menu item corresponding to a location at which the release was performed is selected. Therefore, a user can select his or her menu item using a single touch and drag operation.
Abstract:
A substituted phosphite suitable for lubricating base stocks and thermoplastic polymers represented by the structure: wherein R1 is selected from the group consisting of C1-C22 alkyl and C4-C22 cycloalkyl; R2 and R3 are selected to form a C5-C18 aryl; and R4 and R5 are selected from the group consisting of H, C1-C22 alkyl, C2-C22 alkenyl, C4-C22 cycloalkyl, and C5-C8 aryl. The substituted phosphite may be combined with at least one primary antioxidant as well as other additives.
Abstract:
A ballot or sheet having an anti-copying feature provides for detecting from an image of the ballot or sheet whether the ballot or sheet is an original or is a copy. The anti-copying feature may lighten or darken, or both, when copied and may or may not be evident to the human eye. A reader comprising an imager and a processor is for reading the ballot or sheet and for determining whether the ballot or sheet is an original or is a copy, and for determining selections marked thereon. A method for reading the ballot or sheet is for determining from an image of the ballot or sheet whether the ballot or sheet is an original or is a copy, and for determining selections marked thereon.
Abstract:
A method and system for sharing protection of a mesh network protection domain are disclosed by the present invention. The method includes: presetting a protection ring in the mesh network protection domain, a path of the protection ring running through source and destination nodes of a plurality of services in the mesh network protection domain, and only reserving protection resources on the path of the protection ring; determining protection methods used respectively by a plurality of services said above and configuring a corresponding protection group; setting protection paths of all protection groups on the protection ring, and sharing the protection resources of the protection ring.
