    Abstract: 1573. Stewart, P. Jan. 23. No Patent granted (Sealing fee not paid). Stuffing-boxes. - SLuffing-box packing consists of layers A, Fig. 5, of compound asbestos and wire fabric, which may be impregnated with rubber, plumbago, &c., interspersed with metal strips B, and surrounded, except on the rubbing- surface, by a fabric cover c. The packing may have an elastic backing E. The strips B may be made by folding metal ribbons in the manner shown in Fig. 3, or by stamping a metal plate as shown in Fig. 6. The metal is preferably an alloy containing tin 30, lead 30, zinc 30, and plumbago 10 per cent. [Reference has been directed under Section 7 of Patents &c. Act, 1907, to Specification No. 14,696, A.D. 1892.]

    Abstract: Embodiments of a method and system for acquiring a marine seismic survey are described. One method may include depositing on a seafloor a line of cable sections extending in a first direction. The line of cable sections may have a first end and a second end and may include a plurality of seismic wavefield receivers. The method may also include moving the line of cable sections by collecting cable sections from the second end of the line and depositing cable sections at the first end of the line so that the line of cable sections travels in the first direction. At least one source vessel may be used to provide acoustical waveforms while the line of cable sections is moving. The acoustical waveforms may be received by the plurality of seismic wavefield receivers in the line of cable sections so as to enable generation of a seismic survey.
