A method of plant cultivaton and growth acceleration includes enclosing the plants within a reflective chamber, controlling the CO.sub.2 concentration within said chamber so as to be at least 200 ppm, and irradiating the plants substantially omnidirectionally with a light intensity of approximately 3000 lux, while stably regulating the ambient temperature, relative humidity and nutrient supply.

Method of enhancing plant growth and apparatus for performing the same

An apparatus for monitoring gas dissolved in an electrically insulating oil used in an electrical apparatus comprises a sampling device connected to a tank for sampling a portion of the insulating oil from the electrical apparatus, an extracting device connected to the sampling device for extracting a volume of dissolved gas from the portion of the insulating oil in the sampling device, and a measuring device connected to the extracting device for measuring the components of the dissolved gas. All of the volume of dissolved gas is delivered from the extracting device either by pumping the oil from the tank to the extracting device to force the dissolved gas to the measuring device or by using a plate of the extracting device to force the dissolved gas therefrom. All of the volume of dissolved gas measured is exhausted from the measuring device. The portion of the insulating oil remaining in the extracting device is returned to the tank.

Monitoring equipment for dissolved gas in insulating oil

A system for the automated cultivation of plants includes a plurality of guide rail pairs which support conveyor driven jigs carrying individual plants thereon. As the plants are driven by the conveyors, the driving elements or dogs on successive conveyors are increasingly spaced, so as to allow for the steady growth of the plants. The guide rails are arranged in a radial array to allow for increasing side-wise plant clearance, and are orificed as a means of providing the plants with air and nutrients.

Apparatus for plant cultivation

An automatic analyzer for measuring a combustible gas dissolved in an oil such as an insulating oil in a transformer includes a gas desorbing device, a gas discharger and a combustible gas detector. The oil is sampled and the gas dissolved in the oil is desorbed by bubbling air and a mixed gas of the desorbed gas and air is fed into a bellows type gas discharger and the concentration of the combustible gas is measured by the combustible gas detector.
