Title: Method and apparatus for generating a shock wave beneath the surface of a body of water
IPC: G01V1/133
Filed: 1970-07-29
Abstract: 1323317 Seismic energy generators COMPAGNIE GENERALE DE GEOPHYSIQUE 29 July 1970 [1 Aug 1969] 36774/70 Heading H4D  For marine seismic prospecting a shock wave substantially free from parasitic secondary waves is generated in a body of water by the implosion of a rapidly condensing volume of steam released into the water at a required depth. In the Fig. 2 embodiment a steam injection head hung (with provision for angular adjustment) from the rear of a ship or marine platform comprises a chamber 34 through which steam is circulated by way of inlet pipe 31, apertures 36 and outlet pipe 32. Glass wool insulation 33 surrounds the concentric inlet and outlet pipes. A pneumatic or electrical actuator 50 opens valve 41 briefly to eject steam fromchamber 34 through nozzle 37 into the water. The pressure pulse due to the steam ejection is usually small compared with the following implosion pulse, but both pulses may be used to create a pressure wave-train adapted to a particular seismic prospecting requirement. The start of the steam ejection may be detected by hydrophone 60 to give a time datum for recording the, pressure wave. The steam generating system (Fig. 1, not shown) on board the ship comprises in series a fresh water reservoir (11), a demineralization system (13), a reservoir (15), a boiler (17) and a superheater (19). Steam from the injection head outlet pipe is re-circulated to the reservoir (11) via a condenser (22) which can be purged by connecting the condenser to the superheater outlet.

Title: Improvements in or relating to thermionic valve amplifiers for sound reproduction
IPC: H03G7/02
Filed: 1934-12-29
Abstract: 447,346. Valve amplifying circuits. AIGNER, F., 13, Karlspatz, Vienna. Dec. 29, 1934, No. 37288. Convention date, Dec. 30, 1933. [Class 40 (v)] The volume range fed to a reproducer is increased by controlling the gain of an amplifier through which the signals pass as a modulation on a carrier frequency. The Figure shows a supersonic heterodyne receiver in which energy from the first intermediate frequency amplifier ZF1 is applied to a rectifier which is used to supply anti-fading control to the preceding valves. The output from the rectifier is also amplified and the low frequency applied to a further rectifier G2 which controls the bias of the second intermediate frequency amplifier ZF2 to increase the volume range. The rectification and amplification may be effected in a single diode-triode valve and in wireless reception the arrangement gives suppression of weak signals. In gramophone reproduction the signal is modulated on a local oscillation and the control effected at this frequency.
