Abstract: DIGITAL TO ANALOG CONVERTER                        ABSTRACT     An operational amplifier capable of selectively performing a variety of circuit functions is provided. A single operational amplifier utilizes switched capacitors for sampling and holding an input signal, for establishing a low frequency pole, for applying the sample to an output capacitance to charge the capacitance and for comparing the input signal with a reference.  The multi function circuit provides a large savings in circuit area and permits versatility of circuit applications.  One embodiment of the invention is to utilize a companding DAC having a capacitor array which may be used as the output capacitance of the operational amplifier circuit.  The DAC provided utilizes an R ladder DAC coupled directly to a C DAC and has a switching structure that is simpler than comparable prior art circuits.  The DAC is asynchronous and has programmable A- and Mu-255 law PCM conversion capability.  Coupled directly to the C DAC is an operational amplifier receive filter circuit which utilizes the C DAC as an input capacitor thereby eliminating the need for a buffer amplifier and allowing the DAC to be used for both analog to digital and digital to analog conversion.

Abstract: ABSTRACT A PROCESS FOR UTILIZING TOBACCO DUST_ A process for employing tobacco fines or dust is disclosed.  The tobacco fines are dispersed in an aqueous liquid and applied to tobacco or reconstituted tobacco.          In the preparation of reconstituted tobacco, the fines are incorporated into concentrated tobacco extract before the extract is recombined with the reconstituted sheet or into an aqueous carrier.  The slurry of fines in extract or other carrier is passed through a homogenizer and then is applied as a coating to the sheet prior to drying and shredding.  In application to tobacco strip and other tobacco blend components, the fines are combined with casing and the combination is homogenized to reduce the particle size and produce a uniform distribution.  This is then sprayed by the casing applicator system onto the strip; the dried product is no more dusty in subsequent cutting and handling than is the strip without the added fines.

Whited ABSTRACT         A motor control system wherein the motor windings are energized by sinusoidal excitation currents synthesized from pre-recorded sine values.  The frequency of the winding excitation currents is synchronous with the rotor movement and the phase is a function of the rotor position with respect to the stator. The phase of the winding excitation is additionally controllable as a function of speed or some other adequate system parameter. It has further been found that the total operational speed range of the system is substantially increased by further adjusting and controlling the phase of the excitation currents as a function of the desired speed.
