Abstract: A clock buffer circuit achieves insensitivity to the particular voltage levels and drift therein of input signals used to generate the clock, by use of a differential common gate amplifier (Fig. 1) incorporating an internally generated threshold voltage. Four separate gain paths (2,3,4,5) couple the differential common gate amplifier to an output stage (Fig. 2B). Two of the gain paths (2,5) are used to propagate edges that cause respective abrupt transitions in each direction for a first of two complementary clock signals. The other two (3,4) accomplish the same for the other complementary clock signal. Each gain path is optimized to propagate a leading edge of a particular direction (relative to its point of origin, the direction of the edge inverts as it goes from stage to stage). Of these four gain paths, a first pair (2,5) are used to create a high level of drive for the low to high transitions in the clock signal and its complement. Because of the optimization, this drive cannot be removed as abruptly as it can be applied. A latch-like circuit (6,7) in the gain paths cause early removal of the high level, or hard, drive, leaving in place a maintenance, or holding level of drive. Each holding drive is abruptly removed by an associated gain path in the remaining pair of gain paths. The hard drive is left in place only long enough to ensure that the capacitance of the clock line is adequately charged. An anti-glitch mechanism (Fig. 3A,B) bullet proofs the entire circuit against drive fights caused by ambiguities arising from slow transitions that might arise from the differential common gate amplifier.

Abstract: A document transport apparatus (26) is provided for moving a document (22) along a bidirectional feed line from an upstream area to a downstream area in, for example, an automated teller machine. The document transport apparatus comprises first (36) and second (38) generally planar supports, with the first generally planar support (36) having a first cooperating member (40) and a second cooperating member (42) located thereon. The first and second cooperating members each have ends which have ramp portions (52,54;56,58). In addition, the first and second cooperating members each have an arcuately shaped recess (48,50) therein which faces a second support. The document (22) can be moved between the first and second supports and guided into the arcuately shaped recessed portions of the first and second cooperating members by the ramp portions (52,54;56,58). The ramp portions guide the document between the arcuately shaped recessed portions (48;50) and a drive roller (62) mounted in the second support. The drive roller, when rotated, forces or pinches the document into engagement with the arcuately shaped recessed portions, thereby causing the document to be transported through the document transport apparatus.

Abstract: Long distance soliton lightwave communication systems are considered for next generation application in terrestrial and transoceanic environments. These systems employ a chain of lumped fiber amplifiers interconnected by long spans of dispersion shifted optical fiber. In such systems, resultant pulse distortion and dispersive wave radiation are minimized when the soliton period is long relative to the perturbation length which is the longer of either the amplification period defined in terms of the length of the optical fiber span between consecutive amplifiers or the dispersion period defined in terms of the length over which the dispersion exhibits a periodic characteristic. Additional system parameters for optimized soliton transmission include the relationships of both the path-average soliton power to the normal soliton power and the path-average dispersion from one optical fiber span to the next. Single channel and wavelength division multiplexed systems are disclosed.

Abstract: The invention relates to a method for removing boron trifluoride from the exhaust gases of a vacuum pump, which gases have been obtained when polymerizing α-olefines by using a BF₃-alcohol complex as a catalyst. In a vacuum distillation, the underpressure is achieved by means of a pump sealed with a fluid ring or by means of fluid jet with a torque or ejector pump, possibly assisted by a mechanical booster, such as a propellant circulating pump. In this pump, the fluid ring or the fluid jet is formed by a cocatalyst forming a complex with the BF₃ catalyst, which cocatalyst is an alcohol, preferably butanol.

Abstract: Apparatus for monitoring the composition of a dielectric fluid, in particular for detecting a change in its composition due to the presence of a contaminant. The fluid (2) is held in a two-cell structure (4) in which two portions of the fluid of different thickness (t A ,t B ) are sandwiched by solid dielectric walls (8). A microwave signal is transmitted (5) through the two fluid-containing cells to measure (6,7) the insertion loss for both cells. The signal frequency is chosen such that, for the desired composition, the insertion loss is the same for both cells despite the difference in thickness of the fluid portions. This is achieved by selecting the dimensions and dielectric constant of the cell walls and the dimensions of the fluid portions to control the transmission and reflection coefficients at the cell wall/fluid interfaces. By comparing the transmission through the two cells (A,B), a change in the fluid composition can be detected. The apparatus can be used to monitor vehicle engine oil to detect contamination by water or fuel.
