Abstract: An analytical system and method for detecting volatile organic chemicals in water including a coated SAW detector that provides for improved reduction of moisture at the coating of the SAW detector. A stabilized SAW sensitivity and long lasting calibration is achieved. The analytical system further includes an improved sample vessel and sparger that allow for easy grab sample analysis, while also providing efficient purging of the volatile organic compounds from the water sample. In addition, an improved preconcentrator provides a stabilized sorbent bed.

Abstract: A method for generating power comprising the steps of feeding water into an electrolyzer, providing electricity to operate the electrolyzer to split at least some of the water into hydrogen and oxygen, and decompressing one or both of the hydrogen and oxygen to generate power. Water can be pressurized prior to being fed into the electrolyzer. The hydrogen and oxygen, which can be stored in insulated storage vessels, can be decompressed isentropically to yield energy, which can be used to power a generator. Heat can be extracted from the hydrogen and oxygen, such as through heat exchangers. Hydrogen and oxygen can combine in an internal combustion process to produce work and heat, which can be recycled into the thermodynamic process.

Abstract: A method for generation of gasses contained in a salt solution in accomplished by disposing automated, floating wave power collection vessels in waters distant from shore, the vessels navigating within one or more predetermined geographic zones, having suitable wave conditions for such operation. The wave power devices generating electricity and the gasses are extracted from the salt solution by electrolysis. Automated storage vessels are used as shuttles to deliver the gasses to shore facilities.

Abstract: A method for generation of hydrogen and oxygen contained in a salt solution provides for the disposing a number of wind turbines on navigable collection vessels in waters distant from shore. The wind turbines have a large number of blades, typically 30, to provide high torque for generating electricity used for extracting said gasses from the atmosphere by means of electrolysis. The collection vessels are disposed in predetermined zones, which are changed when weather conditions provide better collection conditions elsewhere. The gasses are stored in cylinders located both on the collection vessels, and on storage vessels attached to the collection vessels. After collection the cylinders are transported to shore facilities for further purification and/or distribution.

Abstract: Improved apparatus for controlling tape speed in a reel-to-reel magnetic tape transport system. A controllable reel drive motor operates in response to a control signal derived from an accumulated count of reel revolutions so that the driven reel is driven at a varying angular velocity chosen to produce a substantially constant predetermined tape speed as the tape is wound. In order to more accurately maintain a constant tape speed an indication of tape speed error is obtained by measuring and comparing with a reference the elapsed time between the writing and recording of a signal using a magnetic head arranged for read-after-write operation, any resulting tape speed error being employed to change the accumulated count in a direction which reduces the tape speed error.
