  • Patent number: 11988058
    Abstract: An apparatus for cutting a conduit in a borehole includes combustible material within a body; a nozzle comprising apertures; a support element between the nozzle and the combustible material, the support element comprising a mixing cavity within the support element; an activation device for igniting the combustible material to form a matrix of combustion products for passage toward the nozzle via the mixing cavity; and a swirl diverter comprising an outer surface having a plurality of helical vanes which extend from one end of the swirl diverter toward an opposite end of the swirl diverter. The apertures of the nozzle are configured to direct the matrix of combustion products from the mixing cavity to the helical vanes, and the helical vanes are shaped to rotate the matrix of combustion products and direct the matrix of combustion products radially outward of the body for cutting the conduit.

  • Patent number: 4723504
    Abstract: An improved pointer and shaft adapter assembly for use in instruments such as the speedometer of a vehicle including an elongated pointer portion and shaft forming portion connected together by engagement between spaced tabs which project from the pointer lying alongside side wall surfaces of an end connector of the shaft adapter. Cooperative nibs and apertures of the pointer and shaft forming portions secure the parts together and prevent any substantial tilting movement therebetween.
