Patent GB-1550701-A (GB)
Title: Seismic data processing system and method
IPC: G01V1/22
Filed: 1976-05-05
Abstract: A multiplicity of sensor groups (21) each containing three seismic sensors is arranged along a cable which is subdivided into sections. All of the sensor groups of a section are arranged at inputs (C1 - Cn-1) of a multiplex device (122) in a transceiver. Each cable section is fitted with one such transceiver each. In order to receive control signals from a central station via control channels and to transmit the seismic signals, received from the sensor groups, to the central station via a data channel, all the transceivers are connected to the central station. In addition to the multiplex device for scanning the analog seismic signals, each transceiver comprises high-pass filters consisting of capacitors (123) and a resistor (140), amplifiers (142, 148) and an output register (3033) with an analog/digital converter (126) for converting the scanned analog values of the seismic signals into digital signals. The control signals emitted from the central station are delayed differently by means of delay lines. Present in each case in each of the said devices is a signal coincidence detector which has the effect that the digital signals stored in the output register pass to the central station when two of the control signals transmitted from the control station arrive simultaneously at the device via the control channels, which in each case have a different signal propagation time. Because the control of the devices is performed by the control signals with different delay times, a multiplicity of devices can be controlled without increasing the number of the control lines in the cable. <IMAGE>

In a centrifugal pump, a diaphragm, normally occluding the liquid inlet and carried by the impeller, carries masses which flex the diaphragm to vary the size of the inlet and by their rotation force the liquid to the discharge. A diaphragm 6, clamped at its periphery between impeller parts 3, 5, abuts an annular inlet portion 5<SP>2</SP> when in the unstressed position. A control spindle 13, fast with the diaphragm 6, can be displaced axially by a governor to move the diaphragm away from the inlet portion 5<SP>2</SP> to admit liquid to the impeller. Centrifugal weights 14 carried by the diaphragm 6 act as impeller vanes to force the liquid to the discharge 11 and also flex the diaphragm to tend to close the liquid entry. The maximum output of the pump can be adjusted by a screw plug valve 12. The weights 14 are of circular section but may instead be constructed as vanes. Alternatively, additional pumping means in the form of vanes extending between the portion 5<SP>2</SP> and the periphery of the part 5 may be provided.
