Title: Incremental electrically actuated valve
IPC: F25B41/06
Filed: 1990-06-11
Abstract: An electrically actuated valve for incremental fluid flow rate control is disclosed.  The valve is comprised of a valve body having an interior with a planar outlet surface against which a rectilinear valve element is slidingly operated.  The valve body includes an inlet orifice and an outlet orifice in the planar outlet surface for fluid flow through the valve body.  The valve element has an orifice therethrough controlling flow through the outlet orifice in accordance with the position of the valve element, which is linearly actuated by a rotary stepper motor.  Linear actuation of the valve element by the rotary stepper motor is accomplished by a shaft extending through and rotating in bearings at opposing ends of the valve body.  A drive key on the shaft interfits a corresponding slot in the valve element and converts rotary motion of the shaft to linear motion of the valve element.

Title: Apparatus and method for reducing distortion in an analog optical transmission system
Inventor: JEFFERS MICHAEL F
IPC: H04B10/54
Filed: 1990-09-04
Abstract: ABSTRACT      An apparatus and method are provided for reducing distortion in an analog optical transmission system.  An analog electrical input signal is split into first and second signal portions.  A laser is modulated with the first signal portion to produce a laser output signal. The laser output signal is split into first and second optical signals, and the second optical signal is converted into a corresponding electrical signal.  Distortion components introduced by the laser are isolated by combining the corresponding electrical signal with the second signal portion of the original analog electrical input signal.  A second laser is then modulated with the distortion components to produce a second laser output signal wherein the distortion components are of equal magnitude but opposite phase to those present in the first optical signal.  The second laser output signal and first optical signal are combined to cancel the distortion components from the first optical signal.
