Abstract
Abstract This invention describes an improved vibrator system having a vibrator comprising two parts, which reciprocate with respect to each other. One part is connected to a first frame which is in operative, force-transmitting contact with the earth. The second part is connected to a second frame. The second frame is connected to the first frame through compliance means. A large mass which rests on the earth, and which can conveniently be a transport vehicle, has a part which overhangs the second frame. Means are provided to alternately support said mass on said second frame, and to support said second frame from said mass. Various configurations of vibrator elements are disclosed, as well as several types of high pressure fluids for driving the vibrator.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
121 words
A system for creating a train of seismic waves in the earth comprising: a. at least one expandable chamber comprising at least two parts reciprocable with respect to each other; b. a first part connected to a first frame in contact with the earth; c. a second part connected to a second frame; d. means to inject a train of pulses of pressurizeD fluid into said chamber; e. a mass resting on the earth''s surface and having a portion over-hanging said second frame; and f. means alternately to place said mass in rigid, non-compliant compressive force-transmitting contact with said second framme, while said chamber is operating, and in tensile forcetransmitting contact with said second frame while said chamber is not operating.
Claim 2
Independent Claim
121 words
A system for creating a train of seismic waves in the earth comprising: a. at least one expandable chamber comprising at least two parts reciprocable with respect to each other; b. a first part connected to a first frame in contact with the earth; c. a second part connected to a second frame; d. means to inject a train of pulses of pressurizeD fluid into said chamber; e. a mass resting on the earth''s surface and having a portion over-hanging said second frame; and f. means alternately to place said mass in rigid, non-compliant compressive force-transmitting contact with said second framme, while said chamber is operating, and in tensile forcetransmitting contact with said second frame while said chamber is not operating.
Claim 3
Dependent Claim
21 words
The system as in claim 1 including at least one compressible compliance connected between said second frame and said first frame.
Claim 4
Dependent Claim
56 words
The system as in claim 1 in which said means to place said mass in rigid, non-compliant compressive force transmitting contact with said second frame comprises a plurality of vertically extensible means arrayed in a two-dimensional pattern between said second frame and said mass to lift at least a part of said mass above the earth.
Claim 5
Dependent Claim
41 words
The system as in claim 1 in which said means to place said mass in tensile force transmitting contact with said second frame comprises means attached to said mass to lift said second frame and said first frame above the earth.
Claim 6
Dependent Claim
24 words
The system as in claim 1 in which said expandable chamber comprises at least a cylinder, and a piston seatably reciprocable in said cylinder.
Claim 7
Dependent Claim
37 words
the system as in claim 1 in which said expandable chamber comprises a cylinder, a piston sealably reciprocable in said cylinder, and means to apply said pulses of pressurized fluid alternately to both sides of said piston.
Claim 8
Dependent Claim
16 words
The system as in claim 1 in which said expandable chamber comprises a closed, flexible-walled chamber.
Claim 9
Dependent Claim
16 words
The system as in claim 1 in which said pressurized fluid comprises a high pressure liquid.
Claim 10
Dependent Claim
16 words
The system as in claim 1 in which said pressurized fluid comprises a high pressure gas.
Claim 11
Dependent Claim
26 words
The system as in claim 1 in which said pressurized fluid comprises an explodable mixture of gases, and including means to detonate said explodable gas mixture.
Claim 12
Dependent Claim
24 words
The system as in claim 1 in which the direction of reciprocation of said first and second parts in perpendicular to the earth''s surface.
Claim 13
Dependent Claim
24 words
The system as in claim 1 in which the direction of reciprocation of said first and second parts is parallel to the earth''s surface.
Claim 14
Dependent Claim
27 words
The system as in claim 1 including fluid leak means connected between the inside volume of said chamber and a low pressure fluid space outside said chamber.
Claim 15
Dependent Claim
49 words
The system as in claim 1 including at least two expandable chambers in series, said second frame connected to the junction between the two chambers, said first frame connected to the two free parts of said two chambers, said pulse of pressurized fluid injected alternately into said two chambers.
Claim 16
Dependent Claim
21 words
The system as in claim 1 including means to alternately clamp and unclamp said second frame to and from said mass.
Claim 17
Dependent Claim
38 words
The system as in claim 1 including means to limit the spacing between said first and second frame so that their spacing is substantially the same as when the weight of the mass rests on said second frame.
Claim 18
Dependent Claim
65 words
The system as in claim 1 in which said second frame is of substantial flexural rigidity and of substantial longitudinal dimension compared to said mass, and said second frame is in rigid, non-compliant force-transmitting contact with said mass at a plurality of spaced points in a two-dimensional pattern; whereby the flexural rigidity of said second frame serves to minimize the flexural vibration of said mass.
