Abstract: ABSTRACT:     A mixer according to the invention comprises a MOS transistor having an ideal quadratic characteristic.    The transistor is of the D-MOST type and comprises a resis-tive gate across which a voltage drop is applied transversely to the longitudinal direction of the channel. The adjustment point of the transistor is chosen to be so that the range of gate voltages between the threshold voltage and the voltage at which the slope reaches the saturation value is always situated during operation within the voltage drop across the gate electrode. The signals to be mixed may be introduced capacitively via a second gate electrode situated above the resistive gate electrode and coupled capacitively therewith.

Abstract: SIGNAL SYNTHESIZER SPECTRUM CONTOUR SCALER            ABSTRACT OF THE DISCLOSURE       A digital signal representative of a first analog signal, such as a voice signal, having varying parameters, such as frequency or amplitude, is converted by a synthesizer into an analog output signal which varies in substantially the same manner as the first signal.  The synthesizer receives a transmitted digital signal representing the first analog signal and synthesizes the varying parameters thereof to provide the analog output signal.  First, the digital input signal is applied to a serial-to-parallel converter and subsequently input to a modulated frequency generator controlled by the operation of a modulation controller.  Digital data processed through the modulated frequency generator is time and frequency scaled, and it is this time and frequency scaling that provides improved accuracy in recreating the proper amplitude relationship of the first analog signal.          Following time and frequency scaling, the processed digital data is input to an amplitude accumulator and subsequently converted into the analog output signal in a digital-to-analog converter.  Time scaling is implemented by apparatus that utilizes the transmitted digital data information to inter-polate between spectrum segments to present a smooth spectrum to the output analog signal.  For frequency scaling, the frequency scaler interpolates between harmonic frequencies of the first analog signal in consecutive frames and the processed digital data of the time scaling.  Both the time domain scaling and the frequency domain scaling are based on the value of a cosine squared function extending between adjacent data points on adjacent frames.

Abstract: FLEXIBLE DISK STORAGE APPARATUS              Abstract A Bernoulli disk storage apparatus includes an elongated slot or groove having a substantial radial elon-gated portion for movably receiving a transducer.  On either side of the groove are air bearing means which induce a pull down force on the record storage disk as it passes over the groove.  By varying selected parameters, the medium-to-transducer spacing is held substantially constant throughout the radial extent of a desired re-cording area.  Further, flutter usually associated with a Bernoulli disk at its outer radial portion is eliminated.

Title: Removal and recovery of nitrogen oxides  and sulfur dioxide from gaseous mixtures  containing them
Inventor: COOPER HAL B H
IPC: B01D53/50
Filed: 1977-08-11
Granted: 1982-08-17
Abstract: ABSTRACT OF THE DISCLOSURE          A cyclic process for removing lower valence nitrogen oxides from gaseous mixtures includes treating the mixtures with an aqueous media including alkali metal carbonate and alkali metal bicarbonate and an oxidant to form higher valence nitrogen oxides and to capture these oxides as alkali metal salts, especially nitrites and nitrates, in a carbonate/ bicarbonate-containing product aqueous media.  Highly selective recovery of nitrates in high purity and yield may then follow, as by crystallization, with the carbonate and bicarbonate alkali metal salts strongly increasing the selectivity and yield of nitrates.  The product nitrites axe converted to nitrates by oxidation after lowering the product aqueous media pH to below about 9.    A cyclic process for removing sulfur dioxide from gas mixtures includes treating these mixtures with aqueous media including alkali metal carbonate and alkali metal bicarbonate where the ratio of alkali metal to sulfur dioxide is not less than about 2.  The sulfur values may be recovered from the resulting carbonate/bicarbonate/sulfite-containing product aqueous media as alkali metal sulfate or sulfite salts which are removed by crystallization from the carbonate-containing product aqueous media.  As with the nitrates, the carbonate/ bicarbonate system strongly increases yield of sulfate or sulfite during crystallization. Where the gas mixtures include both sulfur dioxide and lower valence nitrogen oxides, the processes for removing and recovering lower valence nitrogen oxides and sulfur dioxide may be combined into a single removal/recovery system, or may be advantageously effected in sequence.

Abstract: ABSTRACT An improved sealing composition for use between alumina ceramic parts, or between alumina ceramic and refractory metal, is centered on 47 weight percent Al2O3, 37 weight percent CaO and 16 weight percent BaO.  The composition has a lower liquidus tempera-ture (1325°C) than an otherwise similar one previously used which included 5% MgO, and its thermal expansion coefficient is less affected by dissolved Al203.  As a result, a closer thermal match with alumina ceramic can be maintained during  seal processing and the rejection rate is reduced.

Abstract: A SELF-LOCKING WINDLASS            ABSTRACT OF THE DISCLOSURE          A self-locking windlass for preventing unwinding of the windlass under load when the force turning the windlass is released.  The windlass comprises an eccentric spindle coupled to a shaft and rotatable therewith.  A cable has one end secured to the spindle and its opposite end securable to the load.  Upon rotation of the shaft and spindle, the cable is wound on the spindle pulling the load toward the wind-lass.  Due to the eccentric spindle, a self-locking position of the windlass is attained during each revolution of the shaft and spindle.   In this locking position, the load is incapable of unwinding the cable when the force rotating the shaft and spindle is released.  This locking position is attained when the spindle is substantially between the shaft and load and the load force is directed toward the load along a line that is substantially tangent to the spindle and passes through the shaft.
