Abstract: A coating is formed by chemical vapor deposition an electrically heated filament which is passed through an end plate into a deposition chamber and leaves the deposition chamber through a similar end plate. The filament slides through an entrance passage into the deposition chamber. The entrance passage is formed from misaligned portions which press the filament into direct electrical contact with their walls. A tube communicates with a chamber between the ends of the passage and acts as a sealing means to prevent gas escaping from the deposition chamber through the entrance passage. The end plate operates in exactly the same manner. As no mercury or a low-melting point eutectic alloy is used, no contaminants associated therewith are produced and the resultant coated filament is free of such contaminants.

Abstract: A spline structure, in the form of an aeronautical brake drive bar, has wheel attachment points at its ends for engaging a wheel rim. Each wheel carries a regularly spaced series of these drive bars for engaging friction discs carried by the wheel hub. The main body of each brake drive bar is formed from titanium internally reinforced by composite blocks each comprising a bundle of silicon carbide fibers contained in a matrix that is diffusion bonded within the main body. Other spline structures can be formed in a similar manner.

Abstract: A coating is formed by chemical vapour deposition an electrically heated filament which is passed through an end plate into a deposition chamber and leaves the deposition chamber through a similar end plate. The filament slides through an entrance passage into a first electrode chamber, around part of a wheel electrode into the deposition chamber. The passage of the filament around the wheel electrode provides adequate direct electrical contact. The end plate operates in exactly the same manner. As no mercury or a low-melting point eutectic alloy is used, no contaminants associated therewith are produced and the resultant coated filament is free of such contaminants.

Abstract: An uninterruptable power supply system for producing an AC voltage from at least one of a DC power source or an AC power source includes an input terminal configured to receive an AC voltage from an AC power source, and an inverter operative to produce an AC voltage at an output thereof from a DC power source. A ferroresonant transformer circuit includes a transformer having an input winding, a output winding, and a third winding that forms part of a resonant circuit that produces saturation in the output winding when an AC voltage on the input winding exceeds a predetermined amplitude. A transformer input control circuit is coupled to the input terminal and to the inverter output and is operative to couple at least one of the input terminal and the inverter output to the input winding.

Abstract: A biomass is provided which consists essentially of cells of dinoflagellates of the class Dinophyceae which have been cultivated to produce high cell mass and high DHA content. Biomass consisting of cells of Crypthecodinium cohnii is preferred. The cells are cultivated in an aerobic fermentor to achieve a cell density of a least 10 grams biomass per liter of nutrient solution by maintaining in the fermentor a dissolved oxygen level of at least about 10% of air saturation, and by inducing a stationary phase with a limiting nitrogen source in the nutrient solution. Under these conditions a single cell oil which contains at least 20% docosahexaenoic acid (DHA) in the triglyceride form at a concentration of at least about 1.5 grams per liter of nutrient solution is produced in the biomass. The biomass is suitable as an aquaculture feed.
