A welding system for performing a welding process on a pipe in a confined space includes a motor housing, a weld head assembly and an insertion tube that extends between the motor housing and the weld head assembly with the weld head assembly remote from the motor housing. The motor housing is supported on a platform for rotational and translational movement of the weld head assembly and houses a motor for positioning the weld head assembly relative to the pipe. The weld head assembly includes a clamp assembly for attaching the weld head assembly to the pipe and a weld tool assembly mounted adjacent the clamp assembly for welding the pipe. An arc length gear and a travel gear adjust the distance between a torch assembly and the pipe and adjust the location of the torch assembly around the pipe when the weld head assembly is attached to the pipe.

An air-packing device has an improved shock absorbing capability to protect a product in a container box. The air-packing device is configured by first and second plastic films which are bonded at predetermined portions thereby creating a plurality of air containers, each of the air containers having a plurality of series connected air cells; a plurality of check valves established at inputs of the corresponding air containers for allowing compressed air to flow only in a forward direction; and an air input commonly connected to the plurality of check valves. Through a post heat-seal treatment predetermined edge portions are bonded, thereby creating an inner space for packing a product therein and an opening for loading the product therethrough.

An apparatus and method is provided for controlling and / or halting the uncontrolled flow of petroleum and / or natural gas from an open well head on the sea floor in which the well head is in communication with a subterranean formation. The method includes lowering a fluid control device from a drilling ship to an alignment means positioned above an open well casing through which the petroleum and / or natural gas is flowing in an uncontrolled manner, then lowering the fluid control device through and / or adjacent to the alignment means and into the open well casing until a lower section of a fluid control device enters the open well casing. The fluid control device includes an elongated member at its tip, having a diameter smaller than the inside diameter of the well head casing. A tapered section is in connection with the elongated section, the tapered section, or another section in connection with the tapered section, having a maximum diameter equal to or greater than the inside diameter of the well casing, and an end section in communication with the tapered section having a diameter greater than or equal to the outside diameter of the well head casing. The fluid control device can have a mass sufficiently great to overcome any upward forces created by flowing petroleum and / or natural gas, resulting in sufficient downward movement of the fluid control device and contact with the open well casing to seal same. Alternatively, a drilling rig in connection with the fluid control device can exert sufficient downward pressure thereon so as to overcome the pressure of the flowing petroleum, gas, etc., thereby creating a seal between the fluid control device and the well head.

The present invention discloses a method for freely setting response modes of the operation lever of construction vehicle, according to driver's skills or proficiency and work characteristics, in which the method includes the steps of: receiving a mode signal from a mode selection means, and selecting one of a plurality of selection modes; receiving an operation signal from the operation lever; filtering the operation signal through a filter which is operating in response to the selected response mode; and outputting a filtered control signal.

A torpedo tail mounted dispenser (TMD) for deploying an elongated, flexible article generally along a deployment axis, which includes a receptacle for storing the article in a multiple-turn, multiple-layer configuration about the deployment axis in a storage volume. There is also a torpedo connector mechanism having a terminal forward face and a lateral peripheral surface extending away from the receptacle along the deployment axis. An elastomeric cushioning feature is mounted on the lateral peripheral surface of the connector mechanism. An annular elastomeric bumper is mounted on a forward peripheral face of the cushioning feature, the annular opening of the bumper surrounding the connector mechanism to allow connection of the TMD to a torpedo. The bumper provides protection to the TMD and torpedo under certain shock and vibration levels.

The harness comprises a backplate, a plurality of belts and an attachment. The backplate is arranged on the back of the user. The plurality of belts is configured so that one end of each belt is connected to the backplate and another end of each belt is connected to each other on the front of the user. The attachment is supported by at least one of the backplate and the plurality of belts, and is configured to be attached to the power equipment. The backplate preferably comprises at least one ventilation groove formed on its inner surface and extending to the edge of the backplate, which allows air to pass between the user and backplate easily.

The invention relates to the structure of a water inlet device of a water tank, wherein a float seat is slipped outside an external water-lifting pipe, an internal water-lifting pipe is installed inside the external water lifting pipe, a control valve is fixedly connected on the upper end of the external water-lifting pipe, a valve set is set inside the control valve, the valve set includes a membrane, a positioning plate, a silencing washer, a water feeding plate and a water supply pipe. The shock and vibration caused by inflowing water current may be buffered by using the construction of the valve set, to thereby enhance the silence effect and achieve the purpose of reducing noise.
