摘要： The present disclosure relates to coupling device and valve assembly for use with accessing the water flow in a fire hydrant. Specifically, the present disclosure relates to various coupling device and valve assemblies which are used as a quick connect and disconnect of a fire hose to the hydrant. Additionally, it is advantageous that the coupling device and valve assemblies also provide a self-sealing valve feature, which immediately stops the flow of water when the hose is disconnected from the hydrant. An advantage provided by the present coupling device and valve assemblies is that should a primary valve on a hydrant become unusable, the fire hose can be quickly disconnected from that hydrant and reconnected to a second hydrant without requiring a shutdown of the water grid feeding the disconnected hydrant.

摘要： A method of determining the signature of a seismic source array comprises determining a notional signature of at least one source of an array of n seismic sources from measurements of the emitted wavefield from the array made at 2n independent locations and from the relative positions of the sources of the array and the 2n independent locations. The notional signature of a source may be determined from the difference (or some other function) of the measurements of the emitted wavefield made by the two sensors associated with that source.

摘要： A marine seismic survey is described which uses measurements made in a mid-field region of the source signature to correct an estimate of the far-field source signature as derived from individual contributions of the seismic source elements. The technique reduces the effects of perturbations which else have a considerable impact on the estimation of the far-field.
