Abstract: ABSTRACT OF THE DISCLOSURE This invention relates generally to improvements in fluid flow control systems for parenteral administration of medical liquids. Positive pressure infusion pumps of the syringe type are known.  However, since a portion of each operating cycle with such syringe type pumps is concerned with filling the syringe, rather than delivering fluid to the patient in a pumping mode, the accuracy of such devices tends to fall off, particularly at very high flow rates, where the fill stroke is of significantly large duration relative to the pump stroke period.          The present invention overcomes this deficiency by providing a system for fluid flow control utilizing a syringe pump operated by a stepping motor to repetitively fill and empty a syringe cartridge over a plurality of operational cycles of successive fill stroke and pump stroke periods.          The stepping motor is driven by electrical drive pulses from a digital pulse generation and control system.  Means are provided for maintaining a proportional relationship between the preselected pumping rate and the actual fluid flow pumping rate over each complete cycle of successive fill and pump strokes, the motor drive pulse frequency during each pump stroke is automatically increased to compensate for the time lost during each fill stroke.  A detection device is provided which responds to a high rate of motor drive pulses in the absence of a concurrent selected high flow rate.

Abstract: CONTROL UNIT BRAKING DEVICE                   Abstract of the Disclosure A single lever control unit for sequentially operating a transmission and throttle and, selectively, for operating the throttle independently of the transmission.  A throttle shaft assembly disengages from a throttle gear by pulling out the shaft while in the neutral position.  A double key on the throttle shaft disengages from a keyway in the throttle gear and a spring-loaded pin engages a cavity in the throttle gear to lock both shift and throttle gears in the neutral position.  Throttle only may then be applied.  When the hand lever is returned to the neutral position, the throttle shaft automatically engages the throttle gear and the locking pin automatically disengages by means of spring loading.  The locking pin prevents pulling out the shaft in other than the neutral position.       A spring provides axial loading between the throttle arm connected to the shaft and a friction plate mounted on the shaft.          This loading creates a frictional drag which prevents throttle creep.  Additional throttle braking is achieved during throttling by means of an adjustable screw forcing a friction pad against a   specially profiled side of the throttle gear.       An adjustable flange accommodates a neutral interlock lever.  The flange can be angularly oriented in any desired position.

Title: Ring laser having magnetic isolation of  counter-propagating light waves

Abstract: RING LASER HAVING MAGNETIC ISOLATION OF      COUNTER-PROPAGATING LIGHT WAVES                   ABSTRACT OF THE DISCLOSURE     A ring laser having a nonreciprocal loss element positioned in the aperture of the optical cavity of the laser.  The nonreciprocal loss element is adapted to isolate a pair of plane-polarized counter-propagating light waves from each other.  The isolation reduces the coupling between the waves and thereby reduces the extent of nonlinear mode locking which typically occurs in ring laser gyroscopes when the difference in frequency between the light in the two waves is small.  The isolation is the result of either a spatial or a temporal separation between the counter-propagating light waves.  The nonreciprocal loss element of the preferred embodiments comprises a first optical element having reciprocal optical activity and a second optical element having either reversed or reversible nonreciprocal optical activity.  The nonreciprocal loss element tends to extinguish either the clockwise or the counterclockwise propagating one of the pair of light waves depending on the direction of magnetization in the nonreci-procal optically active element.  In a preferred embodi-ment, the nonreciprocal optically active element is a film of ferrimagnetic material having a domain wall, or magnet-ization reversal, so positioned in the aperture of the optical cavity that two regions of the film having opposite magnetizations each occupy approximately half the aperture. Thus, a counterclockwise propagating light wave passing through the region of the film having one magnetization occupies a different portion of the aperture than is occupied by a clockwise propagating light wave passing through the region of the film having the other, opposite, magnetization.  In another preferred embodiment, the magnetization of the film is modulated cyclically from magnetic saturation in one direction to magnetic saturation in the opposite direction by an externally applied magnetic field.  Only one light wave at a time is thereby permitted to propagate.  The counter-propagating light waves are thus alternately turned on and extinguished so that they do not exist at the same time.
