  • Patent number: 11913311
    Abstract: A flow control shuttle to provide the ability to block flow in either direction initially, while allowing a high-pressure differential capacity in one direction and does not produce free floating pieces of the plug in the flow stream after actuation. The mechanism is actuated by a pressure differential opposite the high-pressure direction, in which the actuation pressure can be set independently of the pressure rating of the high-pressure direction. Upon actuation the flow path opens allowing flow in either direction by moving a shuttle plug from a sealed to an unsealed configuration. The direction of high pressure and actuation pressure can be chosen by direction of installation on based what is required for the application. This mechanism can be incorporated into an existing tool or a new tool design, or can be provided as a standalone tool.

  • Publication number: 20120184167
    Abstract: A composite material formed from a sheet of material (1) consisting essentially of animal hide bonded to a textile material (3). The sheet of material may be leather and the textile material a woven, coated textile. The two materials may be bonded together with a hot melt adhesive which may be provided as a film or web (2). Bonding the sheet material to a textile material increases the dimensional stability of the material when exposed to sunlight and heat, making it suitable for use in the manufacture of sun blinds for vehicles, such as automobiles.
