Abstract: HYDRAULIC CONTROL FOR A TRANSMISSION            Abstract of the Disclosure:            A hydraulic control for an automatic transmission has a plurality of shift control valves for con-trolling the interchange of drive ratios within the transmission.  The shift control valves each have a control chamber subjected to substantially constant pressure and a shift control chamber having an area proportional to the respective control chamber which is subjected to a variable control pressure.  The variable control pressure is controlled at discrete levels by a single pulse width modulator (PWM) solenoid.  The respective area ratios of the shift control chambers to the controlled chambers determines the distinct shift point of each shift valve.

Abstract: Abstract A method of correcting for mis-alignment of the lens in a photocomposing machine is disclosed.  The method comprises establishing a desired base line on a target, forming and projecting a small image through the lens onto the target, rotating the lens until the image falls on the line, measuring the lateral shift of the image due to the rotation, storing electrical signals representative of the shift, and utilizing the signal to correct the motion of the character spacing mechanism when the lens is being used to project characters so as to accurately locate the character images on a recording surface.  Preferably, the image forming step includes projecting a laser beam through a small aperture towards the lens.  The measuring step may comprise establishing a reference position on an array of closely spaced photocells, magnifying the image from the lens and projecting the magnified image onto the array, detecting the distance of the magnified image from the reference position, and con-verting the  distance into electrically coded signals.

Abstract: SPECTACLE LENS HAVING CONTINUOUSLY VARIABLE CONTROLLED DENSITY AND FAST REPONSE TIME ABSTRACT OF THE DISCLOSURE A spectacle lens comprises a liquid crystal layer and electrode assembly sandwiched between a pair of identically curved glass plates and layers of polarization material on the outer surfaces of the plate. The optical density of the lens is controlled by applying across the electrodes variable duty cycle voltage pulses having a magnitude greater than a threshold voltage of the liquid crystal layer and a frequency at least as great as the critical flicker fusion frequency of the eye. The duty cycle of the pulses is controlled in response to ambient light intensity measured by a photocell. In order to reduce response time and increase operating lifetime of the liquid crystal layer, tri-level (+V, 0, -V) rather than bilevel (+V, 0) pulses may be applied to the liquid crystal electrodes.

Abstract: ABSTRACT     Disclosed is a method and apparatus for measuring and controlling volumetric flow rate of gases, and especially for delivering gases at a selected and measured volumetric flow rate.  The apparatus includes a measurement chamber of fixed volume in a flow line, a controllable inlet valve upstream from the chamber, and flow regulator means for establishing constant flow output downstream from the chamber.  Also provided are measuring and control equipment including a pressure sensor in the chamber, means for controlling operation of the inlet valve, timing means, and means for calculating volumetric flow rate.  The method involves closing the inlet valve at a chosen time for a selected interval, to interrupt flow into the measurement chamber, while maintaining constancy of flow out of the chamber.  During at least part of the interval in which the inlet valve is closed, the pressure decrease is measured, and the rate of pressure decrease is calculated by dividing the measured pressure drop by the time measured by the timing means.  The thus calculated rate of fall of pressure is directly related to the volumetric flow rate, which is thus determined.  If the nature of the gas and the flow conditions are such that the supercompressibility of the gas should be taken into account, rate of pressure fall is determined at two time intervals.  If the two rates are the same, no correc-tion is needed.  If they differ, a supercompressibility correc-tion factor is applied to the calculation of rate of pressure fall.
