Abstract: An autoselecting interface for selectively connecting an input aircraft power source to one of two outputs according to a sensed voltage of the input aircraft power source comprises a pair of input terminals for connection to aircraft power sources; first and second pairs of output terminals; a first voltage sensor connected to the input terminals for producing a first trigger output when an AC aircraft voltage is present at the input terminals; a second voltage sensor connected to the input terminals for producing a second trigger output when a DC aircraft voltage is present at the input terminals; a first switch responsive to the first trigger output for electrically connecting the pair of input terminals to the first pair of output terminals; a second switch responsive to the second trigger output for electrically connecting the pair of input terminals to the second pair of output terminals; and an override circuit for disabling the second voltage sensor from producing the second trigger output when an AC

Abstract: A protein-containing fluid, for example, ascitic fluid is removed from a patient by paracentesis. The fluid is held in a reservoir and filtered by a plasmapheresis filter and a positively charged nylon membrane before being in a condition for return to the body. This filtration is designed to remove componants such as cells, cell fragments, fibrin, endotoxins and other particulate contaminations from the ascitic fluid and thus to reduce the incidence of fever and other unwanted side effects.

Abstract: A single-piece protective end cap for insertion into the ends of a tube of rolled sheet material to protect and contain the exposed edges of the rolled sheet material and reinforce the ends of the tube has a central panel with hingedly attached intermediate panels foldable to extend substantially perpendicular to the central panel to collectively form a tubular section with longitudinal edges coincident with the inside surface of the tube for holding the end cap firmly in the end of the tube, and outer panels hingedly attached to the intermediate panels and foldable to extend substantially perpendicular thereto and parallel the central panel to provide a peripheral lip around the tubular section which contains and protects the exposed edges of the sheet material when the end cap tubular section is inserted into the end of the tube.
