Abstract: The top foil (12) of a hydrodynamic fluid film thrust bearing (10) is formed from a single flat annular disk with radial depressions (30) extending from the outer diameter to the inner diameter of the disk that protrude toward the foil plate (16) and define between adjacent depressions a working surface (39) that is configured to complement the foil bumpers (14) attached to the foil plate. The bump foils of the upper foil plate and the bump foils of the lower foil plates can be either in axial alignment or can be displaced relative to each other. When the two sets of bump foils are displaced, the leading edge (31) of the upper bump foils is disposed upstream (relative to the direction of the air stream entering the bump foils) of the leading edge (33) of the lower bump foils.

Abstract: Electronic circuitry is disclosed for interfacing with a plurality of two-position switches to determine if each switch is opened, closed or faulty to some extent. Each switch is connectable in series with a pull-up resistor and between two different voltage values. The switch provides an output voltage at the connection of one terminal of the switch with the pull-up resistor. This switch voltage is presented to both an inverting input of a first comparator and a non-inverting input of a second comparator. The non-inverting input of the first comparator has a reference voltage of a certain value applied thereto, while the inverting input of the second comparator has a reference voltage of a certain value also applied thereto, the reference voltage values being different so as to define a "window" or "dead band" region of voltage. The switch output voltage is compared to the reference voltages on the two comparators. If the switch is closed, the comparator outputs will assume certain states. On the other hand, if the switch is opened, the comparator outputs will assume the opposite states. Finally, if the switch is faulty such that a finite impedance value is developed across the terminals of the switch, the voltage value will then be generated which causes both comparator outputs to assume the same state, thereby indicating a faulty switch to subsequent signal processing circuitry.

Abstract: A welding system includes an imaging system that takes frame by frame pictures of a weld puddle. The imaging system is located in the weld torch. From the images puddle length and width are determined. The length and width are applied against stored membership functions that cover a range of different weld current characteristics and the degree of membership of each dimension in those functions is determined, producing an alpha factor for each membership function. This provides a fuzzy current requirement. Stored values for moment and area for each membership function are multiplied by the alpha for the respective function. The total of the moments is divided by the total of the areas to produce a desired weld current. The weld head includes a weld wire feeder that is driven by a servo by which the wire can be fed along either side of the weld joint. The wire feeder is gear driven in such a way that it does not interfere with the optics in the weld torch. The optics include a strobe to illuminate the puddle. Signal processing includes a process for interpolating the puddle centerline from the range in puddle widths over successive strobed images of the puddle. The head is positioned automatically over the centerline.

Abstract: A fiber laser (26) including a rare-earth doped fiber laser cavity (32) delimited by a pair of reflective elements (28, 30), such as Bragg gratings, is tuned by compressing the cavity (32) and the gratings (28, 30). Because an optical fiber is much stronger under compression than in tension, the laser (26) is tunable over a much broader range than conventional tension/stretching techniques.
