Contaminating spill detection arrangement
First Claim
1. A contamination spill detection arrangement of the type adapted to detect the presense of predetermined contaminants in a body of water and transmit signals to a remotely located receiving station in response to the detected presence of the contaminants, and comprising, in combination:
- at least one detector station means positioned at a predetermined location in the body of water, and said at least one detector station comprising;
detector element means comprising at least one contaminant detector element, said at least one contaminant detector element at least partially submerged in the water, and said at least one contaminant detector element having a predetermined characteristic responsive to presence of the predetermined contaminant thereon and varying said predetermined characteristic for the condition of the contaminant impinging on said at least one contaminant detector element;
sensing means coupled to said at least one contaminant detector element for sensing said variation in said predetermined characteristic, and said sensing means further comprising information signal generating means for generating a first information signal in response to said variations;
transmitter means for receiving said first information signal and generating a transmission signal responsive thereto, and transmitting said transmission signal to locations remote said detector station means;
means operatively connected to said transmitter means for repetitively providing a predetermined on-time period and a predetermined off-time of said transmitter, and said transmission signal generated during said on-time period;
receiving station means spaced from said predetermined location for receiving said transmission signal and generating at least one output signal in response thereto.

Abstract
An arrangement for detecting the presence of contaminants, such as an oil spill, in a body of water. At a predetermined location in the body of water there is provided at least one detector station means having thereon at least one contaminant detector element. The contaminant detector element has a characteristic that changes for the condition of the presence of a contaminant impinging thereon. For example, the characteristic may be a dimension thereof. Sensing means are provided to detect changes in the characteristic and to generate an information signal responsive to such changes in the characteristic. A transmitter means is provided for transmitting a transmission signal responsive to the information signal when there has been a change in the characteristic. The transmission signal is transmitted to regions remote the detector station means. At such regions remote from the detector station means there is provided a receiving station means which receives the transmission signal and provides an output signal such as a control signal or a visual or audible signal in response thereto.
