The apparatus has virtually no stored hydrogen and provides pressurized hydrogen on the demand of a user.

Abstract: An improved process for providing hydrogen from an electrolytic cell having an anolyte solution having an anolyte liquid level; a catholyte solution having a catholyte liquid level; generating oxygen at an oxygen pressure above the anolyte level; generating hydrogen at a hydrogen pressure above the catholyte level; the improvement comprising detecting at least one of the anolyte and the catholyte liquid levels as anolyte level and catholyte level data; feeding the level data to central processing means; determining the pressure differential between the levels from the level data, and pressure adjustment data by the central processing means; and providing the adjustment data to pressure control means to maintain the pressure differential within a selected range. The process offers a low cost method of controlling the pressure differential to within 2 cm WC of a set point.

Abstract: An apparatus and method for remotely measuring emissivity and hence temperature of a surface of an object. The apparatus includes a detector having a radiation receptor for measuring infra-red radiation, an integrating cavity surrounding the receptor for receiving radiation from a surface facing the cavity and delivering the radiation to the receptor, at least two sources of infra-red containing radiation (e.g. light from an incandescent lamp) within the integrating cavity positioned to produce separate beams of the radiation which strike the surface at different angles suitable for reflection to the receptor, and a processor for determining the temperature of the surface from the radiation measured by the detecting means. The use of at least two mutually angled radiation beams compensates for surface anisotropy of the surface whose temperature is to be measured.
