Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for recycling or main-taining the latent heat of vaporization in work produc-ing cycles such as the Rankine cycle by eliminating phase changes by replacing the condenser in such cycles with a compressor and restricting or limiting the expansion to reduce compressor work requirements.  The standard compound turbine prevalent today consisting of a single Curtis stage in tandem with pressure compounded stages has been replaced with several two-row Curtis stages.  An alternative embodi-ment utilizes one or several two-row Curtis stages and a condenser as in the Rankine cycle but limits the expansion, maintaining a relatively high pressure typical in exhaust from this type of turbines.  The high pressure maintains the temperature of the condensate sufficiently high to elim-inate feed water preheating.  Sacrifice of low pressure output is compensated in both cases by salvaging latent heat of vaporization which would not be possible economically, if expansion carried to the maximum.  Sufficient heat is added in the boiler to restore the vapor to its operating condition and to replace any excess heat removed at the final stage of the turbine.

Abstract: MATRIX CHARACTER READING SYSTEM            Abstract of the Disclosure A method and apparatus for selecting the start of an unknown character sensed by a character recognition system.  A multi-channel read head develops a plurality of analog waveforms which form the image of an unknown character sensed by the read head.  After the analog waveforms have been digitized and rectified, static and dynamic threshold values are applied producing a multi-column binary bit map of the unknown character.  The start of the character is detected when two adjacent rows of the bit map are found to have five consecutive binary bits representing a character.  The end of the character is detected when the rows of the binary bits representing background data have a width which is inversely proportional to the width of the character detected.  This information is used by a character recognition apparatus in locating the start of the character and the data generated during a character recognition operation.

Abstract: Abstract In electrically pumped CO2 gas lasers, there take place widely different chemical and physical process which lead, at least partially, to undesirable interactions of the gases among themselves, and/or of the gases with the electrical and/or the optical field and/or with the materials used in the gas-filled chambers.  Bodies that are equipped with surface area-enlarging structures are included in the discharge or resonator chamber or in adjacent secondary chambers.  The secondary chambers by themselves act as reservoirs or as carriers of reservoirs for suitable catalysts and gas components and/or the heating of the catalysts, and have a predetermined influence over the conditions of volume and/or pressure and/or temperature.          The inclusion of such secondary chambers and such structures which enlarge surface area inside the chambers make possible the attainment of at least an approximate state of equilibrium, which leads to uniformly good discharge and long life with high laser efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE A system for adjusting the curvature of the cornea of the eye in-volves inserting a plastic split end adjusting ring into the stroma of the cornea by first making a first incision in the cornea above the corneal ring at about the eight millimeter chord, then inserting one end of a metal split end dissecting ring into the incision with the trailing end of the dissecting ring remaining outside the cornea.  The one end of the dissecting ring has a transverse hole therein near its tip end.  The dissecting ring is held by a magnetic holding and rotating device which has a concave end surface and cir-cular groove therein for receiving the metal dissecting ring and for holding it in a circular shape.  As the holder is rotated the inserted end of the metal ring is magnetically forced to follow rotation of the holder thus the dissecting ring is inserted in a circular path within the stroma.  When the inserted end of the dissecting ring reaches the first incision its rotation is stopped and a second incision is made over the transverse hole in the dissecting ring perpendicular to and intersecting one edge of the first incision.  The plastic adjusting member also has a transverse hole near its one sled shaped end which is placed next to the first incision.  A connecting link member is inserted through the holes in the ends of the respective dissecting and adjusting rings to releasably join the two rings, the rotational direction of the holding tool is then reversed which "backs out" the dissecting ring and at the same time pulls in behind it the plastic adjusting ring.  When the now joined ends of the two rings are rotated back around to the insertion point, the now withdrawn dissecting ring is released from the adjusting ring.  A corneascope type image of the corneal topography is displayed on a visual surface and compared to a desired target image.  Adjustment is then made in the relative position of the ends of the adjusting ring to change the shape of the cornea to bring the image of the present shape into coincidence with the desired shape whereupon the two ends of the adjusting ring are fixedly joined to maintain the desired shape.

Abstract: ABSTRACT In the device used to coat with controllable application thickness a strip of material (1) that passes over a supporting roller (2), the coating medium is applied to the strip of material with the help of a slot nozzle (21) that extends across the width of the strip of material (1). The slot nozzle has a pre-dosing gap (23) the width of which can be adjusted. A dosing lip and the return lip (24) define between them a dosing chamber (25) that extends across the width of the strip of material.  In order to permit a sensitive change in the weight of application with a high quality of coating using simple means, the dosing lip is formed with a wiper bar (6) which is guided on at least one exit side smooth sliding surface (4) of the bed (3) that forms the dosing lip.  The front surface (7) of the wiper bar (6) together with the strip forms a tapering wedge gap, the geometry of which is independent of the application pressure.  The exit edge of the front surface (7) forms a rectilinear and sharp edged strip edge (8).  The wiper (6) is flexible in the area of the front surface (7) and of the stripper edge (8) and the front surface (7) is extremely wear resistant.  The application pressure of the wiper bar (6) against the strip (l) is generated by means of an elastic pressure means (9) between the bar and the bed.
