  • Publication number: 20240110731
    Abstract: Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical impediments such as casing or liners in the heat transfer areas.

  • Publication number: 20070131568
    Abstract: A police officer's utility bag comprising a rectangular fabric body with a zippered top. Hanging file rails from any of several designs are located inside the bag below the zippered top. Side stiffeners are used to hold the shape of the bag, as well as to receive the hanging file rails and a charging fixture for a rechargeable flashlight hanging on the outside of the bag. Various pockets and pouches are provided both inside and outside of the bag. A strap attached to the top can be looped around a passenger seat headrest to hold the top open. A seatbelt clip receives a seat belt shoulder harness to secure the bag in a patrol car seat.

  • Patent number: 6748709
    Abstract: A curtain wall (ACM) system has vertical mullions and horizontal supports which provide a dry as well as a structural system for non-sequential construction of curtain wall exteriors. Internal gutters offer a failsafe moisture proof system. The horizontal and vertical framework members may be mounted in the reverse orientation for special exterior wall configurations. Individual panels can be replaced without sealants or tear down of neighboring panels. A face support for the thin ACM panels is provided. Thermal expansion is addressed with a floating panel on a track design. Alternate embodiment includes transition frame members having glass and metal panel integral supports, freestanding X-Y sub-frame assemblies, fiber optic outboard channels and novel methods of assembly.

  • Patent number: 6725623
    Abstract: Both positive and negative wind loads acting on the surfaces of standing seam roofing often exceed the design capabilities of a particular metal roof, causing the standing seam interlocking vertical seams to disengage. This often results in the roof panels blowing off the roof, causing damage to the roof, the building contents and possible danger to people in the vicinity. A transverse bar is provided across the standing seams of the metal roof. Clamps hold the transverse bar onto the standing seams. At the midsection of each flat panel section of the metal roof a brace descends from the transverse bar. The brace must have a flexible foot member to press down on the panel, otherwise the brace would puncture or otherwise damage metal roof panel. The brace may have an adjustable height adjustment mechanism. Various clamp, bar and foot embodiments are disclosed, all of which provide a structural anti-lift bracket on the roof panel.
