Title: Method of and apparatus for determining the position in space of a plurality of echo receivers distributed along a towed marine cable
IPC: G01V1/38
Filed: 1974-02-21
Abstract: 1456548 Seismic exploration; measuring depth and reading electrically ENTREPRISE DE RECHERCHES ET D'ACTIVITES PETROLIERES (ELF) 21 Feb 1974 [21 Feb 1973] 7987/74 Headings G1G and G1N The positions in space of seismic wave receivers distributed along a towed marine streamer cable are determined by interpolation of position values obtained by measuring, at at least two points along the curve assumed by the cable, the angle between the tangent to the curve at those points and a fixed reference direction. In the embodiment described, six measuring stations are spaced along the cable. Each includes a housing 2 within which are a magnetic or gyrocompass 16, a depth sensor 8, a hydrophone 7, and an electronics package 17. The station is ballasted to give it neutral buoyancy. Compass 16 and sensor 8 each give an analogue voltage output. Hydrophone 7 is used to detect an acoustic pulse transmitted directly through the water, for measuring the distance between the station and the pulse source. The outputs of units 7, 8 and 16 are applied sequentially, in response to command signals sent to the station via conductors in the cable, to an oscillator to modulate its frequency about a centre frequency. The FM signal resulting is sent along a further conductor in the cable to the towing ship, together with similarly-derived FM signals from the other stations. The centre frequency is different for each station so that the FM signals can be separated at the ship. The separated signals are  digitally recorded and processed to interpolate the positions of the seismic receivers between the stations. A control console on the ship includes display and system-test facilities. The invention is useful when the seismic receiver positions need to be known accurately for common-depth-point processing of seismic traces.

Abstract: 639,841. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. March 26, 1947, No. 8218. [Class 39 (i)] [Also in Group XL (c)] A cold cathode gas-filled discharge tube of the type described in Specification 639,827, in which a sequence of discharges occurs successively across a series of gaps, has the cathode formed of a wire helix 3<1>, or alternatively a screw-thread, the successive turns of which form the respective individual cathodes all co-operating with common anode plates or rods 2, 2<1>, the cathode being coated with alumina over all but small areas on each turn directly opposite the anodes. A projection 6 on anode 2 provides a reduced gap for starting on an initial pulse being applied at 10, Fig. 3, showing the tube used in an arrangement to generate two alternate pulse trains. The ionization from the first gap lowers the striking potential of the adjacent gap and thus the gaps all strike in succession, sending out a train of pulses from the secondary of transformer 8. The end turn of the helix 3<1> is uncoated, so that the cathode glow travels round it and initiates a further discharge sequence along the other side of the helix. The discharges are extinguished by negative pulses applied to terminals 10, 101. A simpler form of the tube, Fig. 1 (not shown), has only one anode.

Class 38(5) Upon the occurrence of overload in a winding 12, a plunger 13, delayed by a dashpot 12a, rises and lifts a trippirig element 14, pivoted at 15, so that a lever 17, pivoted at 18, is freed and moves to the left under the action of a spring (not shown) opening  contacts 9, 10 in the circuit of a contactor  winding and so causing the breaking of the main circuit to be protected; the upward  movement of the contactor armature raises a stud 25 which rocks a bell crank lever 23 pivoted at 22 so that its other arm 24 restores. the lever 17 to its original position where it is again latched.. In the form shown the contactor controls a three-phase circuit and has three movable bridging con-  tacts controlling the three phases and a fourth bridging contact shunting a "start" button. Depression of the start button thus energizes the contactor magnet which closes the four bridging contacts, the fourth contact completing a maintaining circuit for the contactor magnet. When the contactor opens as described above, it can only therefore be reclosed by a subsequent operation of the "start" button. The contacts 9, 10 may also be opened by pressing a "stop" button 11 which engages and moves to the right the sliding contact 10 which is pivoted to the lever 17 at 19. The contact 9 is pivoted at approximately 16 and is engaged by a roller. 20 on the lever 17 which moves it to the right at a greater rate than the contact 10 moves so that the contacts 9, 10 separate. The Provisional Specification refers to Specification 774,072. Reference has been directed by the Comptroller to Specification 583,716.

Abstract: 250,564. Regnauld de Bellescize, H. J. J. M. de. April 8, 1925, [Convention date]. Addition to 226,784. Eliminating effects of disturbing currents.-In the method of eliminating disturbances from a sinusoidal current described in the parent Specification, both parts of the differential apparatus now include a resonant circuit each comprising a constant resistance. The transformer T2, Figs. 3 and 5, which transmits both signals and disturbances alike, has a comparatively large metal section carrying a small number of turns, whilst the transformer T1, in which the hysteresis effect is utilized ta eliminate the relatively-feeble sinusoidal impulses, comprises a section S2 in series with a relatively small section S1 carrying a large number of turns. The combined output it applied to the grid of the valve L3 through an adjustable tapping P, so that the disturbing voltages are balanced out. Condensers C1, C2 enable the phases of the currents to be more effectively opposed, whilst the condenser C3 ensures the symmetry of the secondary circuit. The valves L1 and L3 may be replaced by two pairs of valves arranged in parallel. Fig. 6 shows a supersonic receiver comprising differential stages L1, L2 adjusted so as to suppress disturbances of different intensities. Specification 237,547 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a resistancecoupled amplifier, Fig. 7 (Cancelled), in which the amplification is such that sinusoidal currents in the input circuit I swing the plate current of the last valve between the upper and lower limits of the characteristic curve. This produces a counter-electromotive force across an adjustable resistance V, which can be arranged to counterbalance the sinusoidal component. This subjectmatter does not appear in the Specification as accepted.

Abstract: 738,681. Melting glass by electric heating. GENERAL ELECTRIC CO., Ltd., ADAMS, O., and HAWKINS, F. S. March 15, 1954 [March 27, 1953], No. 8586/53. Class 39 (3). A solid body of glass or an aggregate of glass particles is melted or softened by initially heating a surface layer thereof by placing two electrodes initially in contact with one another at the glass surface, passing a current through the electrodes and drawing them apart a short distance along the glass surface to form an arc, whereby the glass melts and becomes conductive, the distance apart of the electrodes being gradually increased until the required part or the whole of the glass is melted by passage of current therethrough. When glass in a glass furnace melting tank is melted by gas or oil flames, some of the glass in apertures in the side walls through which electrodes are to be inserted for passing current through the glass is left unmelted; and this glass is melted by inserting two small wedge-shaped auxiliary electrodes initially in contact with one another into the aperture on to the glass, separating them to form an arc, pressing one or both electrodes into the glass as it softens and passing current through the glass until sufficient is melted to allow the main electrodes to be inserted in the downwardly inclined apertures. The auxiliary electrodes are small wedge-shaped graphite rods with insulating handles and are connected in series with an impedance of a few ohms to an A.C. 30-amp. supply at 100-200 volts, the voltage being increased as the electrodes are separated. Glass in other apertures may be similarly softened, e.g. for tapping a tank. Specification 723,606 is referred to.
