    摘要: Methods and apparatus are provided for a torque driver including an axially displaceable gear with a biasing assembly to bias the displaceable gear into an engagement position. A rotatable cap is provided with a micrometer dial to select a desired output torque. An intermediate bevel gear assembly is disposed between an input gear and an output gear. A gear tooth profile provides a separation force that overcomes the bias to limit torque at a desired torque limit. The torque limit is adjustable and may be adjusted manually or automatically depending on the type of biasing assembly provided. A clutch assembly automatically limits axial force applied to a fastener by the operator to avoid alteration of the desired torque limit.

    摘要: Methods and apparatus are provided for a torque driver including a displaceable gear to limit torque transfer to a fastener at a precisely controlled torque limit. A biasing assembly biases a first gear into engagement with a second gear for torque transfer between the first and second gear. The biasing assembly includes a pressurized cylinder controlled at a constant pressure that corresponds to a torque limit. A calibrated gage and valve is used to set the desired torque limit. One or more coiled output linkages connect the first gear with the fastener adaptor which may be a socket for a nut. A gear tooth profile provides a separation force that overcomes the bias to limit torque at the desired torque limit. Multiple fasteners may be rotated simultaneously to a desired torque limit if additional output spur gears are provided. The torque limit is adjustable and may be different for fasteners within the same fastener configuration.

    摘要: A system for recovering and recycling gases is disclosed having, in one aspect, inlet and outlet flow lines and controllers with an inflatable enclosure which, in one aspect, has a series of one or more inflatable rib stiffeners which, in one aspect, are inflatable by the gas to be stored. In one aspect the system does not present gas at an undesirable back pressure to the gas source. In one aspect a filtering relief valve is employed which prevents environmental airborne contamination from flowing back into the system when the relief valve is closing. In one aspect the system is for storing and re-using helium.

    摘要: In a valve, the valve poppet member is constructed from a spring material where a tubular wall portion has a spiral wall configuration intermediate of a supporting base and a valve head. The spiral wall configuration has inner and outer diameters, a specific number of revolutions with a spiral width and a width of material remaining to provide sufficient cantilever strength to support the valve head and has the desired spring rate to seat the valve head on a valve seat.

    摘要: Methods and apparatus are provided for a torque driver including a laterally displaceable gear support member to carry an output spur gear. A biasing assembly biases the output spur gear into engagement with a pinion to which is applied an input torque greater than a desired output torque limit for a threaded fastener such as a nut or screw. A coiled output linkage connects the output spur gear with a fastener adaptor which may be a socket for a nut. A gear tooth profile provides a separation force that overcomes the bias to limit torque at the desired torque limit. Multiple fasteners may be rotated simultaneously to a desired torque limit if additional output spur gears are provided. A gauged selector mechanism is provided to laterally displace multiple driver members for fasteners arranged in differing configurations. The torque limit is selectably adjustable and may be different for fasteners within the same fastener configuration.
