Abstract: A steam distributor that uses a porous metal plate to replace the conventional screen plate of a steam shower for distributing steam to a moving web such as the web of a paper making machine. Steam showers using a steam distributor with this porous metal plate can deliver extremely uniform steam to the surface of a paper web. Profiling steam showers constructed by using an array of the steam distributors are able to deliver the best profiling results for various paper products. The porous metal plate can be considered as an equivalent of a screen plate with thousands of micro-orifices arranged tightly in both the machine direction and the CD direction.

The preferred method also includes counting the number of the test results that do not satisfy the predetermined criteria, and generating an indication that a predetermined quantity of the test results do not satisfy the predetermined criteria if at least the predetermined quantity of the test results do not satisfy the predetermined criteria.

Abstract: The invention concerns a Coriolis mass flowmeter comprising at least one conduit (9) traversed by the mass, which produces mechanical vibrations under the effect of an excitation unit (8) and acts as an oscillating element, whereof the oscillating behaviour which varies based on the mass flow rate is sensed by at least one sensor (15, 16) to determine the mass flow. The invention aims at determining the degree of wear of the conduit (9). Therefor, the excitation unit (8) applies a single excitation pulse to the conduit (9), whereof the oscillatory response is sensed by the sensor (15; 16). The invention is characterized in that an evaluating unit (10) arranged downstream calculates the initial dampening constant recorded when the conduit (9) was new.

Abstract: The invention relates to a two-wire transducer in automation engineering that outputs a measurement signal as an injected current. For the method to test the serviceability, it is proposed to increase the DC loop current (IS), independently of the measured value, from the minimum value towards the maximum value (ISM), and to measure the input voltage (UE) across the internal resistance of the transducer in the process, and to compare it with a definable threshold value (UES) that is greater than the minimum input voltage (UEM) required to maintain serviceability. If the input voltage (UE) falls below the threshold value (UES) before the DC loop current (IS) has reached its maximum value (ISM), the DC loop current (IS) is reduced until the input voltage (UE) reaches at least the definable threshold value (UES), and the error is signaled.

Abstract: An industrial robot that uses a simulated force vector to allow a work piece held by the robot end effector to be mated with a work piece whose location and orientation is not precisely known to the robot. When the end effector makes contact with the location and orientation in which the other work piece is held the robot provides a velocity command to minimize the force of the contact and also provides a search pattern in all directions and orientations to cause the end effector to bring the work piece it is holding in contact with the other work piece. The search pattern and the velocity command are continued until the two work pieces mate.

Abstract: A robotic wash cell is provided and includes a six-axis robotic arm and end effector equipped with nozzles that spray unheated, solvent free, pure water at high-pressure to clean or debur objects by maintaining the nozzles in close proximity and substantially normal to each surface being cleaned or edge being deburred. The robotic cell wash is particularly useful for cleaning contaminants such as oil and grease from items having more complex shapes. The six-axis robotic arm positions the nozzles and their sprays substantially normal to each surface being cleaned or deburred. The nozzles produce a multi-zone spray pattern with a continuous effective cleaning zone. A water recycling and pressurizing system collects the used water, separates out the oil and grease contaminants to a level of about 5 ppm, and pressurizes the pure water to about 3,000 psi for washing operations or about 6,000 psi for deburring operations.
