Abstract: Abstract An automatic control system for a vehicular liquid sprayer includes a control circuit for receiving a liquid presure signal and a vehicle ground speed signal and operator accessible controls for delivering to the control circuit signals corresponding to a desired application rate, to the number of nozzles associated with the vehicular liquid sprayer and to the nozzle spacing. The operator may vary the input signal corresponding to desired application rate plus or minus a given percentage to compensate for tolerances in the liquid sprayer system. The control circuit calculates the liquid pressure necessary to achieve the desire appli-cation rate and the difference between this desire liquid pressure and the measured liquid pressure and produces control signals corresponding to this difference. A duty cycle control circuit converts these control signals to a cyclical control signal for driving a motor-driven flow control valve. The duty cycle of this cyclical control signal varies in proportion to the magnitude of the pressure difference. This duty cycle controlled signal is automati-cally modified to overcome inertia and motor lag time in a motor driven flow control valve, and to shut off the valve at a given minimum operating pressure.

Abstract: MODULAR SHAFT ENCODER                         Abstract Disclosed is an optical encoder structure which is easily attached to a motor case and shaft in either the factory or field, and which automatically achieves, by its construction, both axial and radial alignment. This is achieved by first securing to a housing by a novel latch, a mounting plate which is spaced a predetermined distance from the housing.  A rotatable encoder disc, having a conically shaped hub is placed in an aperture in the housing, the conically shaped hub serving to self center the disc radially relative to the housing.  The assembly is pushed onto the motor shaft, and the disc is secured to the shaft.  The plate is then attached to the motor case and the housing rotated.  This moves the housing into an abutting relationship with the plate and spaces the housing a predetermined distance from the disc.  Thus the disc is both axially and radially positioned, no instruments being required to accurately position the housing with respect to the disc or motor.  Moreover, so that no electrical adjustment is necessary in either the field or in the factory, the aperture for the mask or slits of the stationary member of the optical encoder and the transparent or slit openings on the rotating member are made equal to the period of the rotating disc pattern divided by two.  This creates a half-wave rectified analog waveform which in conjunction with direct feedback of the voltage created by the analog waveform to control the code cycle, operational amplifier saturation is inhibited.

Abstract: ABSTRACT      "THE MANUFACTURE AND EXPRESSION OF LARGE STRUCTURAL GENES"           Described are rapid and highly efficient procedures for the total synthesis of linear, double stranded DNA sequences in excess of about 200 base pairs in length, which sequences may comprise entire structural genes.  Novel sequences are prepared from two or more DNA subunits provided with terminal regions comprising restriction endonuclease cleavage sites facilitating insertion of subunits into a selected vector for purposes of amplification during the course of the total assembly process.  The total, finally-assembled sequences include at least one, and preferably two or more, unique restriction endonuclease cleavage site(s) at intermediate positions along the sequence, allowing for easy excision and replacement of subunits and the correspondingly facile preparation of mul-tiple structural analogs of polypeptides coded for by the sequences.  Manufactured genes preferably include codons selected from among alternative codons specify-ing the same amino acid on the basis of preferential expression in a projected host microorganism (e.g., E. coli) to be transformed.         Illustrated is the preparation and expression of manufactured genes capable of directing synthesis of human immune and leukocyte interferons and of other biologically active proteinaceous products, which products differ from naturally-occurring forms in terms of the identity and/or relative position of one or more amino acids, and in terms of one or more biological and pharmacological properties but which substantially retain other such properties.

Abstract: ABSTRACT OF THE DISCLOSURE         A disconnecting device is inserted in a two-wire com-munication loop near the far end thereof.  The device contains a latching winding of a latching relay which winding is inserted in series with one side of the loop.  The winding controls two nor-mally closed contact pairs, one pair being inserted in series with each side of the loop to disconnect a far end telephone or the like when the winding is energized.  A shunt diode and capacitor prevent activation of the latching winding by normal battery and signal current.  Reverse polarity voltage of greater value than normal battery will activate the latching winding and effect far end disconnection.  A reset winding of the relay is connected in series with a diac, a diode, a time constant resistor and a normally open pair of contacts of the latching relay, across the loop.  Each of the normally closed contact pairs is shunted by a resistor to permit current flow past the contacts when open.  A capacitor storage and timing circuit is connected with the reset winding of the relay to accumulate sufficient voltage when normal battery polarity and potential is restored to cause the diac to conduct and the relay to reset.  The impedances are related so that a disconnection can not be achieved when the telephone is in the ON-HOOK mode and there is no fault in the loop.  Reconnection can not occur while the telephone is OFF-HOOK.
