Title: Method and apparatus for cancelling reverberations in water layers
Inventor: HAGGERTY PATRICK EUGENE
IPC: G01V1/20
Filed: 1955-05-18
Abstract: 777,647. Geophysical prospecting. TEXAS INSTRUMENTS, Inc. May 18, 1955, No. 14376/55. Drawings to Specification. Class 118 (2). A method of making a seismic survey record of a water-covered area wherein the bottom is a good reflector causing standing waves to be set up by reverberations in the water layer comprises using two seismometers positioned to receive the said standing waves 180 degrees outof phase and combining the outputs of the seismometers such that these unwanted signals cancel out. It is pointed out that location of seismometers at standing wave nodes would have to be precise whereas positioning them at antinodes is not very critical. Several arrangements of seismometer spreads are described wherein two seismometer streamers are moved through the water at two distinct depths. The depths chosen will vary according to whether pressure or velocity sensitive types of seismometer are used, and to which harmonic of the fundamental frequency is used. Use of an amplifier with a suitable bandpass characteristic avoids unwanted harmonics (though perhaps received at one detector) from being recorded or interfering with the cancellation effect. In Fig. 5 (not shown) a ship tows a floating cylindrical " fish " carrying two reversible motors controlled from the ship to lower two weights respectively. Each weight has attached to it a seismometer streamer and may carry pressuresensing elements connected to instruments on board the ship to help in maintaining the streamers at the antinode depths calculated from knowledge of the depth of the water layer. If velocity type seismometers are used for the top streamer this streamer may be positioned at the velocity antinode of the fundamental frequency of the standing wave, viz., the water surface. Apparatus wherein the depths of the spreads are fixed before being placed in the water and remain constant throughout the recording process may consist of a steel tension member and a conductor cable bound together and supported in the water by a series of floats, seismometers being suspended from this at the required depths for each particular seismic prospect. The seismometers of the lower spread may be suspended from those of the upper spread as in Fig. 6 (not shown). Since the velocity antinode of the fundamental frequency exists at the water surface whilst the pressure antinode exists at the bottom, using appropriate seismometers one spread may be positioned near the surface by a floating cable and the other spread near the bottom by floating the seismometers on short leads from a heavier-than-water cable, as in Fig. 7 (not shown).

Abstract: 363,947. Discharge apparatus ; code telegraphy. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. May 16, 1931, No. 14580. Convention date, May 30, 1930. [Classes 39 (i), 40 (iii), and 40 (v).] A discharge tube contains a pure gas or vapour whose atoms can be in a metastable condition and which is ionized by light containing rays of frequencies absorbed by the metastable atoms of the gas &c., the intensity of the rays being such that the conductivity of the gas decreases ; a gas or vapour whose atoms cannot be ionized by the metastable atoms of the main gas &c. may be added to the filling. As shown in Fig. 1, the tube 1 has two electrodes 2, 3 and contains neon at a pressure of 1À5 mm., to which helium may be added. The tube is irradiated by a discharge lamp 7 containing neon and shaped as a coil surrounding the tube. A voltage indicator 6 is connected in parallel with a resistance 5 which is connected in series with a battery 4 across the tube 1. Light from the lamp 7 causes metastable atoms of neon in the tube to be brought into a non-metastable state such atoms soon returning to the fundamental state; a reduction of current is produced in the tube and the voltage across the resistance 5 is increased. A saturated diode may be inserted in the circuit of the tube 1 so as to maintain the current constant. The tube may be used as a relay or for the reproduction signals &c. recorded on films. For example in transmitting by radiotelegraphy, a film provided with light. and dark spots in the form of Morse signals is passed over a slit in a screen covering the tube 1. The U-shaped tube 13 shown in Fig. 2 contains neon and has electrodes 14, 15 producing a luminous discharge and electrodes 16, 17 producing a discharge which is controlled by the luminous discharge. A film 21 may be moved between the limbs of the tube. The electrodes 15, 17 may be combined.

When the lid of the skip comes against the framework 21, the gears 12, 15, 14 and the drums 9, 10 are held, and the carriage ascends the runway. At the top of the incline the winch is stopped and reversed, and the skip lowered.
