  • Patent number: 7753388
    Abstract: Embodiments of the present invention comprise a lightweight front wheel drive recumbent road bicycle and an associated frame. A front triangle is provided to which the drive train of a standard road group can be attached and utilized. A telescoping tube assembly is provided in the front triangle to permit the distance of a bottom bracket and crankset from a seat pan to be adjusted for riders of different sizes. The handlebar is coupled to an end of the telescoping tube assembly and no traditional handlebar stem attached to a steering tube is utilized, so that the structure provides maximum stiffness to better capture the input of the arms and upper body when maximum power is required. The seat pan and a seat back are integrated with the main frame truss structure to help ensure the maximum transfer of the rider's energy to the drive train.

  • Patent number: 7013916
    Abstract: An apparatus for containing and delivering hazardous gases at sub-atmospheric pressure from a pressurized container is provided which includes a valve body in sealed communication with an outlet orifice of the pressurized container. The outlet orifice of the pressurized container is open to an interior chamber of the pressurized container. A fluid discharge path is located in the valve body, between the outlet orifice of the pressurized container and an outlet orifice of the valve body. A pressure regulator having a pressure sensing means capable of responding to sub-atomospheric pressure, is integral to the valve body, in-line in the fluid discharge path with the pressure regulator pre-set to a pressure below atmospheric pressure to allow the gas to be delivered through the regulator from the interior chamber only when the pressure regulator senses a downstream pressure at or below the pre-set pressure.

  • Publication number: 20040256398
    Abstract: An exterior impact and abrasion resistant protective coating (14) is provided on the surface of the vessel (12) having information (16, 18, 20) provided on the exterior surface thereof to form a container (10) for storing and dispensing gas under pressure. The coating (14) is sufficiently transparent such that said information (16, 18, 20) is visible through the coating (14). One advantage of the invention is that any labels (16, 18, 20) on which the information is provided are protected against abrasion and other damage that would otherwise obscure the information thereby reducing the frequency with which the labels (16, 18, 20) need to be replaced.

  • Patent number: 6648021
    Abstract: A modular gas control device for use with a compressed gas cylinder (111) comprises a primary module (152) and a secondary module (252) mounted on the primary module. The primary module comprises a first supporting body (154) having a first main gas flow path (155) through the body. The supporting body has input connecting means (156) for mounting the body on the cylinder (111) and connecting the gas flow path (155) to communicate with the gas cylinder through a first flow path (157). Pressure reducing means (166) provides gas in the flow path at a lower pressure than in the container. Output connecting means (170) downstream of the pressure reducing means provides a low pressure outlet from the main gas flow path. A high pressure shut-off valve (164) is positioned upstream of the pressure reducing means, and filling means (161, 160) allows filling of the cylinder with compressed gas through the input connecting means (156) along a second flow path (159) separate from the input flow path (157).

  • Patent number: 6572688
    Abstract: Gas is admitted to an in-container purification unit 202 via an inlet 212 located at or near the gas discharge end 220 of the unit. This feature is advantageous because it allows a liquefied gas container to be filled to a level above the second end of the body of the unit without the problem of dispensing liquefied gas.
