Abstract: INVENTION :  SYSTEM FOR SYNTHESIZING                 SOUNDS ASSOCIATED WITH PRINTED MATERIALS          INVENTOR  :  MICHAEL NITEFOR            ABSTRACT OF THE DISCLOSURE           A speaking device adapted for use with display material consisting of visual data (such as printed text) and associated bar code is described.          The speaking device includes an optical wand for sensing the bar code and producing a control signal intended to trigger the reproduction of speech sounds associated with the visual data.  A speech synthesizer stores sets of control data for use in audibly reproducing the speech sounds.  Speech synthesizing circuitry responds to each control data set by releasing the speech sounds associated with the control data set.  A microprocessor is programmed to respond to the control signals generated by the optical wand to select from memory the control data set corresponding to the required speech sounds.

Abstract: ABSTRACT A liquid cyrstal display device having high extinction ratio polarizers on the input and output sides of a transmissive, twisted nematic liquid crystal cell. The liquid crystal cell incorporating a dichroic dye which is admixed with the liquid crystal material. The high extinction ratio polarizers get the full contrast and density capability from the liquid crytal cell while the dichroic dye prevents the buildup of the contrast limiting orthogonal mode of the polarized light passing therethrough, thus, further increasing the optical contrast and density. Such an arrangement provides optical contrasts of around 150:1 with a 10 micron thick liquid cyrstal cell.

Abstract: Abstract A system for autotransfusion has an aspirating wand or tube coupled to a vacuum source through a reservoir for receiving aspirated blood.  From that reservoir blood flows to a receiving bag in a rela-tively low position below the elevation of the pa-tient.  When there is sufficient blood supply in the bag, the bag  is elevated from its lower position to a point higher that the patient.  Blood then flows from the elevated bag by gravity through a conduc-ting tube and a needle into the patient.  When the bag is then substantially empty, it is again lowered to an elevation lower than the patient for repeti-tion of the operation.  If desired, an anticoagulant can be introduced into the aspirated blood.

Abstract: A B S T R A C T     A high pressure hydraulic fluid-flow transducer has a frusto-conical throat obturated by a valve member which is fixed to a spindle slidingly carried in a bearing which is fixed to the one-piece housing. The bearing engages a substantial length of the spindle, to prevent wobbling, closely adjacent the smaller throat end. The housing has internal screw-threads at both ends, for connecting the sensor into an hydraulic system.  Because the compression spring is upstream of the valve member and acts upon the upstream end of spindle, the valve member and throat are both readily accessible through the downstream end of the housing, both for inspection purposes and for machining of the throat before insertion of the valve member and spindle.          Reverse fluid flow is possible by virtue of a second spring, acting between valve member and spindle.
