Abstract: The method of determining the magnitude of the differential static correction between two selected adjacent receiver points D, E, in a linear seismic array, that involves the steps of: recording a first multi-trace record responsive to a first seismic wave generated at a first source point C on one side of D, E at any distance; recording a second corresponding multi-trace record responsive to a second seismic wave at a second source point F on the opposite side of D, E at any distance; correlating a first trace CE with a second trace CD of the first record to obtain a first time difference R; correlating the corresponding first trace FD with a second trace FE of the second record to get a second time difference S; and determining the value of K = (R - S)/2, where K is a value of the static correction equal to the difference in the travel time through the weathered layer at D and E. The process can be repeated for other positions of C, F to obtain other independent values of K. The various values of K can be averaged to provide an improved value of differential static correction at receiver points D, E. The method is applicable also to determining the differential static correction at two adjacent source points.

Abstract: Improvement in electro-fluid vibrator means used for generating seismic waves in the earth in which the flow of pressurized fluid to the vibrator is controlled in accordance with the resultant holddown pressure on the baseplate in contact with the earth, so that there is always a positive pressure on the baseplate, preventing it from being lifted off the surface of the earth. Force measuring means are provided in the holddown means. So long as this force is large and positive (in the direction to hold the baseplate to the earth) no control is required. When this positive force becomes less than a preselected value, the pressure fluid system is controlled to reduce the maximum pressure of, or rate of flow of, pressure fluid to the vibrator. The force measuring system can conveniently utilize the compliances in the holddown system as the force measuring elements.

Abstract: In a seismic system in which signals from a plurality of geophones are carried by pairs of conductors to each of a plurality of array terminals, where the geophone signals are converted to square wave signals, and on successive commands, the square wave signals are sampled, the samples are temporarily stored, and are then transmitted to storage means, the improved method of transmitting the geophone signals from the geophones to the array terminals, comprising; amplifying and square waving the geophone signals at the geophones, and transmitting the square wave signals to the array terminals. Included also are steps to modulate carrier signals in synchronism with the square wave signals to form bursts of carrier signals which are transmitted to the array terminals, where the bursts of carrier signals are detected and the square wave signals are regenerated, and sampled.

Abstract: This invention is concerned with methods and apparatus for recording multiple exposure holograms on a film record and displaying reconstructed images of the separately recorded subjects. Means are provided, by the use of simultaneous application of multiple different reference beams, to reconstruct a plurality of images, each of which can be separately controlled in intensity or other random parameter. Also, the recording of the separate subjects can be controlled in a predetermined timed sequence, and the corresponding reconstruction of the plurality of images can be controlled in the same or different timing sequence. Means are provided for recording the separate subjects by keeping the subject and reference beam in fixed directions and rotating the plane of the recording film sheet or strip.Encoding of the hologram record is accomplished by means of a beam scrambler which introduces random parameters, e.g. intensity variations or random path length differences, in either the reference or object beam during the formation of the hologram. The same or identical random parameter means is used during reconstruction of the hologram to decode the identifying indicia.

Abstract: A control system for a seismic vibrator, in which the reference, or sweep signal, drives the vibrators directly without the need to control the vibrator so that the seismic signal generated in the earth will be inphase with the reference signal. Instead, the output of one or more sensors on the vibrator are used to generate a "transmitted" signal which is representative of the seismic signal generated in the earth. The transmitted signal is used to phase-shift the reference signal to provide a counterpart signal which is inphase with the transmitted signal. The counterpart signal is used to correlate with the received seismic signal.A plurality of vibrators may be used. They may be grouped together at one point, or they may be spaced apart at independent points. The vibrators may use the same or different reference signals, and may start simultaneously or at delayed times.An improved sensor for mounting on the vibrator is described to provide information as to the absolute displacement of the base plate during vibrator operation.

Abstract: Method and apparatus for logging the position of a deep borehole filled with liquid in the earth, comprising a long, continuous small diameter pipe adapted to be reeled up on a drum mounted on a vehicle, and means to insert the end of the pipe into the mouth of a borehole and to lower it to any desired depth in the earth. A plurality of geophones are positioned on the surface of the earth in the vicinity of the borehole with conventional amplifying and recording means connected thereto. Means are provided on the vehicle for compressing a liquid or gas, and injecting it into the pipe. On the bottom end of the pipe is a chamber in which this pressurized fluid can be stored. Fast acting valve means are provided which on signal can suddenly open and permit the stored fluid in the chamber to explosively expand into the liquid in the annulus of the borehole. Such explosive injection of the fluid from the chamber into the well will cause a seismic wave to be generated which will expand until it reaches the surface and is detected and recorded by the geophones. Electrical control wires may be carried in the pipe means by which the valve can be timed and controlled, so that the travel times of the seismic wave from the chamber to the geophones can be determined, from which the position of the borehole at the depth of the chamber can be determined.

Abstract: There is disclosed apparatus and method for unerasably marking computer and other information records and the like in a precise, machine readable manner so as to identify the particular record, and to control access to the record by providing means for authenticating a control member presented for access to the record. The illustrated system involves preparing a master card of opaque material through which micro patterns have been burned by a laser. This master is used to produce a facsimile pattern in a control member and/or the record to be identified and retrieved. The facsimile card is used as control member and the micro pattern compared with a bank of unique micro patterns to authenticate the pattern bearing control member and to identify the record bearing a similar micro pattern. The bank of master micro patterns may comprise a plurality of master cards, or may conveniently be on a reel or strip of material, with separate frames or areas, each having its unique pattern of microperforations, with an index corresponding to the indicia of individual patterns. Details of such an indexed bank are disclosed in our copending application Ser. No. 272,739.
