Abstract: A contaminant recovery apparatus may have a sprayer attached to a front portion of the apparatus and operative to delivery droplets of molten wax to oil spilled in water or on ground. The apparatus may further comprise a take up system which picks up wax after it has solidified and absorbed the oil. The take up system may be attached to the rearward portion of the apparatus. The apparatus may also have a separation system which separates the wax and the oil. The reclaimed wax can be reused to pick up more spilled oil. The reclaimed oil may be refined for fuel.

Abstract: An implantable bioartificial active secretion system for providing a physiological secretion such as insulin necessary for functionality of a physiologic activity such as glucose metabolism of a living-being host. The system includes a housing implantable within the host in fluidic communication with tissue fluid indicative of secretion need. A chamber within the housing contains a plurality of physiologically active, autonomously functioning, live secretory cells for producing the physiological secretion. A periodically operating pump apparatus moves tissue fluid into contact with the secretory cells for pick up of the regulating physiological secretion for subsequent physiologically-effective dispensing into the host while avoiding immunorejection of the host body or of the host to the secretory cells.
