  • Patent number: 12201208
    Abstract: A sling for use with a ballistic shield, wherein the sling may be fastened with a release buckle and tightened. Excess strap may be secured in a glide buckle and can be trimmed to fit. An optional security webbing loop adds stability against strap sliding. Ambidextrous buckles near the handle grip allow versatile connection and use. The shoulder strap hooks onto the lower strap, enhancing stability.

  • Patent number: 12058989
    Abstract: An angling device comprising a housing arranged with an arm with a pivot to the housing at a proximal end and a line capture jaw at a distal end, a location means for location of the line capture jaw in use on a line of an angling rod, and a mechanism for pivoting the arm from a second position where the line capture jaw locates on the line in a second location on the rod, to a first position where the line capture jaw locates on the line in a first location on the rod, wherein the mechanism is activated automatically after movement of the line to the second location on the rod.

  • Publication number: 20230223766
    Abstract: Battery cells and other types of energy cells are not produced identically, and the performance and degradation of the cells vary over time. This makes it challenging to balance and manage stacks of cells arranged in series. A battery circuit is provided that includes each cell having an inline switch that is in series with the respective cell, and an outline switch that is parallel to the respective cell and the inline switch. When the inline switch is open and the corresponding outline switch is closed, the respective cell is electrically isolated from the stack. Specific cells within a stack can be electrically isolated to vary power, balance the circuit, remove damaged cells, and provide rest to the cells to extend the lifetime usage of the cells.

  • Patent number: 10816533
    Abstract: The invention concerns a method of marking a hydrocarbon liquid comprising the step of adding to said liquid, as a tracer compound, a compound of Formula I or Formula II: wherein at least one of R1-R6 in Formula I and at least one of R7-R14 in Formula II is selected from: i. a bromine or fluorine atom; ii. a partially or fully halogenated alkyl group; iii. a branched or cyclic C4-C20 alkyl group; iv. an aliphatic substituent linking two positions selected from R1-R6 in Formula I to one another or two positions selected from R7-R14 in Formula II to one another; or v. a phenyl group substituted with a halogen atom, an aliphatic group or halogenated aliphatic group and none of R1-R6 in Formula I and none of R7-R14 in Formula II being a sulphonate group or COOR15, where R15 represents H, C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, C3-C15 cycloalkyl or aryl.

  • Patent number: 9538843
    Abstract: An item of table furniture has a table top and a table frame supporting the table top. The table top, in plan view, is formed with first pair of opposite edges and a second pair of opposite edges. One edge of the first pair of edges is convex and the other edge of the first pair of edges is concave. The convex curvature and the concave curvature of the first pair of edges has a predetermined first radius of curvature of substantially equal size. One edge of the second pair of edges is longer than the other edge of the second pair of edges. Such a table can be arranged together with items of table furniture of the same kind and also with other items of furniture to an array in many ways.
