Abstract: Laser cladding system (102) is used to accumulate the build-up of material on a substrate by heating a localized spot on substrate forming a melt pool into which material is fed to create a deposit having a physical dimension. Optical detection means coupled to an optoelectric sensor which receives light through an apertured mask are used to monitor a physical dimension of the deposit, and a feedback controller (104) adjusts the laser in accordance with the electrical signal, thereby controlling the rate of material deposition. In the preferred embodiment, the physical dimension is the height of the deposit, and the system further includes an interface (106) to a computer-aided design system including a description of an article to be fabricated, enabling the feedback controller (104) to compare the physical dimension of the deposit to the description and adjust the energy of the laser (110).  The feedback controller (104) includes circuitry for adjusting the laser (110).

Abstract: A method whereby a composite clad metal ingot can be produced for onward processing at higher temperatures which are sufficient to allow the properties of the substrate material to be adequately controlled to meet specific requirements. These higher temperatures are required to avoid the undue levels of work hardening which occurs at the lower temperatures previously employed because of the need to avoid the formation of deleterious intermetallics at the bonded clad substrate interface. Such intermetallics are formed at temperatures above approximately 850 °C and should they be present, will weaken or destroy the bond. The ingot, consisting of a steel or stainless steel substrate which is clad with a corrosion resistant metal, preferably of titanium, zirconium or their alloys, and containing an interlayer of high melting point metal of tantalum, niobium (columbium) or their alloys, is processed at temperatures above 900 °C. The tantalum or niobium interlayer prevents the formation of the deleterious brittle intermetallics which would otherwise be formed at these temperatures.  Consequently, these higher temperatures can be used to control the steel properties by the conventional and prescribed methods of the art and without regard to the effects that they would otherwise have upon the bond.

Abstract: Methods and apparatus for performing near lossless-concatenated N-level constrained quantization Hadamard transform decoding are provided.  Accordingly, the present invention provides a transform-based coding technique, where the coding loss introduced during repeated encoding and decoding is reduced to a substantially insignificant level. This is accomplished by employing a constrained quantization and inverse quantization operation in each level of encoding/decoding in the decoder. In this manner, the concatenation error between each level of a decoder is reduced to a substantially minimum level and the quantization error introduced during quantization operations, i.e., originally at the encoder and in each level of the decoder, is substantially reduced.  Thus, the decoded bit stream that is output at the N-th level of the decoder is substantially the same as the original bit stream provided to the input of the encoder.
