Abstract: A ground effect vehicle wherein a flap coupled to a spoiler is provided on the wings in order to break lift when the craft starts to leave ground effect travel in order to avoid flight out of ground effect.

Abstract: A seismic data processing system utilizes vibration type shock waves which are delivered by a reactive mass (52) acting in conjunction with a base plate (50) to output low frequency shock waves to the earth. The force signals for the reactive mass (52) and (50) are measured and input to a transmitter (42) for transmission to a receiver (48) at a control center (28) which also receives resultant measured data. The measured force signal is input to a data correlator (74) as a model signal and correlated with the resultant data to provide processed data out.

Abstract: A real time seismic telemetry system includes a central station (10) for communication with a plurality of remote data acquistion units (14). The command station (10) has a command unit (34) for controlling the operation of a transmitter (40) for providing instructions to the data acquistion units (14). The data acquistion units (14) receive the data on a receiver (80) and process the data in a logic control circuit (88). Remote data is picked up with a hydrophone (30) and converted to digital data for transmission through a transmitter (78) which is tuned to a discrete channel for each data acquistion unit (14). The command station (10) has a PCM receiver (62) tuned to each of the channels for demodulating the data stream therefrom. A digital receiver (66) is provided for synchronizing and processing the data. The digital receiver (66) synchronizes both to the bit rate and to the beginning and ending of the digital word such that data contained in the digital word can be multiplexed onto a data bus (68).

Abstract: An auxiliary fuel system for installation beneath the rear portion of the floor pan of a passenger car. The auxiliary fuel tank in the system is resistant to leakage even when the car in which it is installed is subjected to a rear end collision. The system increases the survivability of the auxiliary fuel tank by the use of transversely extending support straps which permit the longitudinal forward and downward movement of the auxiliary tank during said collision, to thereby help prevent its being crushed. The tank's ability to move downwardly as it moves forwardly during said collision is enhanced by the tank being provided with a sloping front wall which deflects the front of the tank downwardly as it encounters a transverse member in the car, and by the tank also being provided with a large, relatively shallow fuel storage area designed to bulge during said collision, thereby also tending to force the tank downwardly away from the car.

Abstract: An energy conservation indicator for use in an enclosed locality adapted to be heated and/or cooled to temperatures maintained within limits recommended for energy conservation purposes comprises a thin disc of transparent material, having a backing provided with contrastingly colored printed matter and images of parts of a human face, such as eyes and eyebrows. A first configuration of encapsulated liquid temperature-sensitive crystals is arranged between the disc and the backing below the eyes to represent the image of a mouth on the face. The liquid crystals are of such a nature as to reflect incident white light through the disc at temperatures between a recommended upper temperature for heating and a recommended lower temperature for cooling, and said first configuration of the crystals constitutes an upwardly arced curve which, when activated, imparts to the face a frowning countenance to thereby indicate to an observer that the temperature in the locality is not within the recommended limits.
