A dragline excavating machine includes a gearless direct drive AC drive motor for driving each of the hoist and the drag drums in the system. The gearless AC motor is driven using a digital system which receives AC power from the utility system rectifies the power using active front end circuits, and converts the resultant DC to a frequency controlled AC using an inverter circuit. The resultant AC signal is employed to drive the gearless AC motor, resulting in reduced harmonic distortion, unity ...

Toilet bar compositions are described that contain specific odor masking agent(s). The odor masking agent(s) reduce malodor without the need for elevated amounts of masking fragrances that individuals may not prefer and who use the composition for personal cleansing or who are exposed to the composition.

An integrated spectral sensing system includes a spectral engine comprising an optical filter assembly bonded to an energy sensitive array. The optical filter assembly and energy sensitive array collectively configured to sense energy transmitted through the optical filter assembly and to generate data based on the sensed energy. An energy source generates energy for impingement upon the spectral engine. A sample interface has a chamber for containing a sample, sized and configured to match the ...

The present invention relates to a product of reaction between an amino functional polymer comprising at least one primary and/or secondary amine and one or more active ingredient. By the present invention, there is provided a release of the active component over a longer period of time than by the use of the active itself.

A detector system, filter therefor, and method of making same is disclosed. The filter includes an interference element having a reflection band disposed primarily in the near infrared, and having a high transmission over most of the visible region. The filter also includes an absorptive element that absorbs light non-uniformly over the visible region. The filter when combined with a semiconductor photodiode or other suitable detector yields a detector system whose spectral responsivity closely ...

The MEMS flexible film chopper/shutter device provides reliability, efficiency, noise reduction and temperature fluctuation compensation capabilities to the associated electromagnetic radiation detector. An electromagnetic radiation detector having an electrostatic chopper/shutter device includes a detector material element and flexible film actuator over...

Techniques for producing a color profile that characterize the color response of a color imaging device involve the use of a gray backing material. The gray backing material is placed behind a sheet of output media during measurement of color elements in a reference image formed on the output media. The gray backing material may be particularly useful for output media that is very thin or slightly transparent. In particular, unlike black or white backing materials, the gray backing material prod...

A fairing arrangement for bridging an aircraft fixed structure (14) and a control surface (10) hingedly mounted on and angularly displaceable with respect to the aircraft structure is provided, together with a method of producing a flexible seal member for such an arrangement. The fairing arrangement includes first and second fairing portions (22, 24) on the fixed aircraft structure (14) and control surface (10) respectively with an intermediate flexible seal (26) disposed between them. The flex...

A cartridge heater for mounting in the bore hole of a device to heat the device, having an improved release coating to facilitate the removal of the cartridge heater from the bore hole subsequent to operation at elevated temperatures, wherein the release coating is a fast-drying, graphite-based solid film lubricant that bonds to the heater.
