Abstract: A closed loop fiber optic gyro features signal processing wherein square wave phase modulation is added to a modulation drive signal after overflow logic so that the square wave modulation will not cause a phase modulation ramp to exceed overflow/underflow logic limits. The arrangement is such that the phase modulation causes a retrace with each modulation period when the amplitude of the ramp is within predetermined limits. Corrections to the retrace limit are implemented so as to scale a digital output, which enables the determination of accumulated gyro angle with a finer resolution than simple output pulse accumulation as has heretofore been the case.

Abstract: A computer system includes a bus and a plurality of devices coupled to the bus. A CPU within the bus controller generates addresses for data transfers to and from the devices. A bus controller generates control signals for the data transfers. A data transfer rate controlled by the control signals is varied so that the data transfer rate is optimal for data transfers to and from each device. The data transfer rate for a data transfer to or from a first device is based on a subset of address bits used by the CPU to address the first device.

Abstract: The method of regulating a voltage produced by a generator with a voltage regulator according to a battery charge state includes providing a controller containing a clock and a memory able to store battery and power supply reference data, battery voltage and generator rotation speed; maintaining a regulated voltage produced by the generator at a normal value (U.sub.R) during a first time interval (t1); measuring a battery voltage (U.sub.B) and decreasing the regulated voltage (U.sub.R) during a second time interval (t2); determining the battery charge state from the measured battery voltage (U.sub.B) according to the stored battery- and power supply-reference data; and, when the battery charge state is determined to be unsatisfactory, determining an additional time interval (t4) with the controller and an amount of increase of the regulated voltage (U.sub.

Abstract: A 16 mm rotary microfilmer that operates in 25.times. duplex mode that simultaneously photographs both sides of a document. Each side of the document is imaged onto a separate roll of film resulting in greater resolution and easier readability. The microfilmer gives the same numerical address to the images of each side of the document so that the images of the front and rear of the document are easily mated to each other and identified as a single document to reduce confusion in the retrieval process.

Abstract: A process for removing unwanted contaminant metallic oxide from the surface of a nickel branding layer of an electronic circuit package, in order to enhance the affinity of a layer of phenolic branding ink to the surface of the metallic branding layer involves treating the surface of the metallic branding layer with a hydrogen-containing, chemical reducing gas phase ambient, so that oxygen within the surface oxide chemically combines with the hydrogen component within the ambient, so as to form readily removable water. The surface of the metallic branding layer is thereby substantially free of surface oxide, providing a greater surface area of metallic-ink bonding sites. As a consequently, a subsequently deposited layer of branding ink strongly adheres to the surface of the nickel and is not readily removed during further cleaning of the circuit package.

Abstract: A process for the piecing of a yarn end on a open-end spinning machine. The yarn is backfed a first time from a cross-wound package, the backfeeding is interrupted and the yarn is clamped at a predetermined distance from the package and the free end is cut. The backfeeding is then resumed for a predetermined period of time and the yarn is temporarily stored between the clamping point and the package. The stored yarn is then wound onto the package in a plurality of parallel windings upon a predetermined generating line. The yarn clamp is released to backfeed the yarn remaining in the temporary storage device and to stretch or tension the yarn between the package and the backfeeding means. The yarn is reclamped and the excess yarn is cut to a predetermined length. The yarn is backfed to the spinning rotor of the open-end spinning machine to combine with fibers in the rotor to piece up the yarn, which is then drawn off the rotor and wound onto the package.

Abstract: An improved apparatus for delivering energy to two field applicators includes a power divider electrically coupled to a planar transmission line connecting the two field applicators. The power divider receives an input microwave signal and delivers a first power signal to an applicator along a first leg of the line, and delivers a second power signal to the other applicator along a second leg of the line. The power divider is coupled to the transmission line at a point which is remote from the applicators such that the power signals will encounter substantially identical discontinuities as the signals are coupled into their respective applicators.

Abstract: A closed loop fiber optic gyro features signal processing wherein square wave phase modulation is added to a modulation drive signal after overflow logic so that the square wave modulation will not cause a phase modulation ramp to exceed overflow/underflow logic limits. The arrangement is such that the phase modulation causes a retrace with each modulation period when the amplitude of the ramp is within predetermined limits. The square wave amplitude from a cycle immediately after a retrace is considered as errant data that should be excluded from a phase nulling loop. Thus, the phase nulling loop has more accurate input data so that feedback will be accomplished more effectively for improved gyro performance.
