Abstract: Example split valves for regulating a first flowrate and a second flowrate of a fluid within a closed loop systems are disclosed herein. An example split valve includes an electrohydraulic servo valve coupled to a first piston via a first hydraulic flowline and a second hydraulic flowline, the first piston to include a piston shaft, a first head, and a second head; one or more bellows fixed to at least one of the first head or the second head, the one or more bellows to hermetically seal the fluid from a hydraulic fluid; and a control system connected to the electrohydraulic servo valve, the control system to adjust the first flowrate and the second flowrate of the fluid through a first fluid chamber, the first piston to be located in the first fluid chamber.

Abstract: A urinary catheter assembly (10) having a folded, compact configuration and a straight ready to use configuration, having an outer tube (30) and an inner catheter tube (12), the inner catheter tube comprising a bendable region (24), the inner catheter tube and the outer tube being movable relative to one another so that a bending element of the bendable region of the inner catheter tube is moved into the lumen of the outer tube, thereby straightening the inner catheter tube so as to place the urinary catheter assembly into a straight ready to use configuration.

Abstract: A satellite emergency voice/data downlink method and apparatus that sends cockpit audio and flight data to a satellite communications system upon detection of a serious event or a pilot generated signal.

Abstract: An improved stylus assembly for replacing state of the art compressed air powered scribing tools, said stylus stem and point being monolithic and capable of operation indefinitely without failure of the stem, requiring only infrequent sharpening of the scribing tip.
