Abstract: METHOD FOR PRODUCING COLOR REPRESENTATIONS OF QUANTIFIABLE  DATA BY MAXIMIZING DIFFERENTIAL PERCEPTION OF COLORS           ABSTRACT OF THE DISCLOSURE      A method is described wherein quantifiable data which have arbitrary dynamic ranges and which vary as a function of other para-meters are represented in color.  A set of subranges, without re-striction in number, representing data properties are associated with a color set in such a way that the colors are perceived to be maxi-mally differentiable by interpreters, whether human, electronic, or other, by specifically incorporating information concerning the normal or anomalous characteristics of the interpreter's color perception when determing the color set.  The method further provides for the realization of color displays by directly associating the colors with densities, transmittances, or illumination levels for negatives, posi-tives, or colored light emitting devices, whether the realization re-quires primary additive or primary subtractive hues.

Abstract: L'invention est relative à un appareil de mesure de la concentration d'hydrogène gazeux dissous dans une substance liquide.  L'appareil comporte une cellule électrochimique constituée d'une membrane polymérique en contact avec un échantillon de la substance liquide et perméable à l'hydrogène, d'un électrolyte apte à provoquer une réaction d'oxydation de l'hydrogène diffusé à travers la membrane polymérique au niveau d'une première électrode et une réaction de réduction d'un gaz oxygéné au niveau d'une seconde électrode, de sorte à générer un courant proportionne à la concentration d'hydrogène à mesurer.  Une électrovalve éjecte, lorsque actionnée, l'échantillon de la substance liquide à l'extérieur de cellule électrochimique à un instant donné du processus de mesure.  En outre, un circuit amplifie une tension correspondant à la valeur du courant proportionnel à la concentration, lequel circule à travers une résistance de charge montée en dérivation entre les première et seconde électrodes et  l'entrée du circuit amplificateur.  Un dispositif d'affichage est relié à la sortie du circuit amplificateur et fournie une mesure numérique de la concentration en hydrogène de la substance liquide.  Un ensemble de commande contrôle les instants de mise en fonctionnement de la cellule électrochimique, de l'électrovalve ainsi que du dispositif d'affichage  numérique suivant une séquence prédéterminée.

Abstract: PROGRAMMABLE LOGIC ARRAY ADDER                         ABSTRACT     This specification discloses a multi digit binary adder embodied in programmable logic arrays (PLAs).  The particular programmable logic array used here has a separate two bit decoder for receiving each like order pairs of digits Ai, Bi of two n digit binary numbers A0, A1....An-1 and Bo, B1....Bn-1 plus a carry Cin.  The decoders generate an output signal called a min term on a different line for each of the four possible combinations AiBi, Ai?i, ?iBi and ?i?i of the true and complement of each pair.  The min terms from the decoders are fed to an array called the product term generator or AND array which generates product terms fP = f0(A0,B0) f1(A1,B1)....fn-1(An-1,Bn-1) fn(Cin) The product terms are fed to a second array called a sum of product term generator or OR array that sums product terms fp.          A series of latches is last in the sequence of logic elements making up the PLA.  These latches each perform an AND function to generate a sum bit Si that is an AND of two functions supplied by the OR array to the inputs of the latches to generate a sum S0, S1....Sn-1 plus a carry Cout for the adder at the output of the PLA.  The adder is optimized for a PLA with latches that perform an AND function.

Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE     A disposable surgical stapling instrument for forming and implanting surgical staples in the skin or fascia of a patient to close a wound or incision.  The instrument comprises an elongated body having a forward portion and a rearward portion serving as a handle portion.  The forward portion of instrument body houses a staple driver attached to a staple driver actuator and a return spring for the staple driver actuator. A surgical staple magazine assembly is affixed to the lower edges of the instrument body forward portion.  An anvil plate, supporting a row of surgical staples, is located within the magazine assembly.  The anvil plate terminates at its forward end in a coextensive anvil surface.  The magazine assembly contains a feeder assembly to constantly urge the row of staples toward the anvil surface to locate the forwardmost staple of the row thereon to be implanted and formed thereabout by the driver and to disengage a formed staple therefrom.          The magazine assembly also provides a channel for the lower end of the staple driver and a staple retaining surface to minimize bending of the staple crown during the staple forming operation. The staple driver is shiftable between a retracted position and a staple forming position by means of a trigger pivotally mounted to the instrument body forward portion and operatively connected to the staple driver actuator.

Abstract: ABSTRACT OF THE DISCLOSURE             A portable thread dyeing kit comprises, preferably, a plurality of separate compartments each containing a liquid dye with an integral felt piece inside the compartment, the felt piece reaching into the dye and being soaked with same.          Near the top of each compartment is a pair of orifices in opposite side walls of the compartment for transversely passing a needle through the container and through the respective felt piece.  Accordingly, as a white thread is passed through the appropriate felt piece, the thread is dyed to the respective color.  The device is extremely simple and thus inexpensive to produce as it avoids split arrangement of absorbent pads used for the same purpose in prior art.

Abstract: PATENT APPLICATION of ARTHUR KARP     for TRAVELING WAVE TUBE WITH  NON-RECIPROCAL ATTENUATING ADJUNCT     Abstract Oscillations due to backward waves in a high-power traveling-wave tube (TWT) are inhibited by a non-reciprocal attenuating device which essentially absorbs only backward waves.  A directional coupler mediates the exchange of energy between the TWT interaction circuit and an external circuit containing a non-reciprocal loss element such as a ferrite isolator.  In such embodiments the high-frequency power handled by the isolator is much less than the power in the TWT interaction circuit.  The frequency band handled by the isolator is much narrower than that handled by the TWT.  Coupling to the loss element is through  one or more resonant circuit elements such that a "notch" of attenuation is obtained for a backward wave only, at a certain frequency where oscillations are prone, such as the frequency associated with 2.pi. phase shift per cavity in a coalesced-mode coupled-cavity TWT.     lrksrbnll2778         - 1 -                  78-56
