Abstract: An iron-based alloy comprises 1.5 to 2.5 wt% of C, 0.25 to 4.75 wt% of Ni, and W and V in quantities surrounded by the line L as shown in Fig. 1 of the attached drawings with a balance of Fe and inevitable impurities. The iron-based alloy is obtained by a first heat treatment for applying a solid solution treatment by rapidly cooling the iron-based alloy from a temperature of an austenite forming temperature or more to consequently obtain a mixed matrix comprising a base matrix of martensite and remaining austenite phases and a non-molten carbide, and a second heat treatment for cooling the iron-based alloy after precipitating an MC  type carbide within an eutectoid transformation temperature range to consequently precipitate a low carbon content austenite phase.

Granted: 2007-07-17
Abstract: The logging tool of this invention includes a transmitter conveyed on a drilling collar for exciting a quadrupole signal in a borehole being drilled by a drill bit and a receiver for receiving the signal. The transmitter is operated at a frequency below the cut-off frequency of the quadrupole collar mode. The received signal consist s primarily of the formation quadrupole mode which, at low frequencies, has a velocity that approaches the formation shear velocity . The transmitter, in one embodiment, consists of eight equal sectors of a piezoelectric cylinder mounted on the rim of the drilling collar. The value of the cut-off frequency is primarily dependent on the thickness of the drilling collar. Alternatively, the transmitter may be operated to produce both the collar mode and the formation mode and a processor may be used to filter out the collar mode .

Abstract: The invention relates to a device and method for generating liquid capillary streams of multi-component immiscible liquids, the diameter of which may range from tens of nanometers to hundreds of microns and to a relatively monodispersed aerosol of electrically charged multi-component droplets generated by rupture of the streams due to capillary instabilities. Said immiscible liquids flow at appropriate volumes through metal needles that are connected to a high voltage source in such a way that all the needles are contained inside one needle. The needles may or may not be placed concentrically relative to one another. The electric forces extrude the streams thereby resulting in diameters ranging from 100 microns to a few nanometers. The device and method disclosed in the invention can be used in fields such as materials science and food technology, wherever generation and controlled handling of structured micrometric and nanometric sized streams is an essential part of the process.

Title: Method of providing void spaces in gypsum wallboard and in a gypsum core composition
Inventor: SETHURAMAN GOPALAKRISHNAN
IPC: C04B28/14
Filed: 2002-06-17
Granted: 2011-01-25
Abstract: The invention provides a method of providing void spaces in gypsum wallboard and in a gypsum core composition such that the weight of the gypsum product is reduced without deleteriously affecting its mechanical properties. More specifically, the invention provides a method of providing void spaces in a gypsum wallboard comprising the step of adding air bubbles having different relative stabilities to a gypsum slurry, wherein the less stable air bubbles are sufficiently unstable such that they coalesce on contact with each other in the slurry to form larger air bubbles, and the weight ratio of the less stable air bubbles to the more stable air bubbles initially added to the slurry is such that there are a sufficient number of more stable air bubbles to prevent a majority of the less stable air bubbles from becoming large enough to rupture before the slurry sets sufficiently to prevent the slurry from filling void spaces left by ruptured bubbles. The method further includes the steps of mixing the air bubble-containing gypsum slurry to distribute the air bubbles throughout the slurry to form a core composition of gypsum wallboard, depositing the core composition on a cover sheet, and, applying a second cover sheet over the core composition to form a gypsum wallboard.

Abstract: A sketch-based change detection technique is introduced for anomaly detection and other applications that can benefit from having a quick and efficient change detection mechanism. The technique is capable of detecting significant changes in massive data streams with a large number of network time series. As part of the technique, we designed a variant of the sketch data structure, called k-ary sketch, uses a constant, small amount of memory, and has constant per-record update and reconstruction cost. A variety of time series forecast models are implemented on top of such summaries and detect significant changes by looking for flows with large forecast errors. Heuristics for automatically configuring the forecast model parameters are presented. Real Internet traffic data is used to demonstrate that the sketch-based change detection method is highly accurate when compared with per-flow analysis, and can be implemented at low computation and memory costs. The results validate using the technique as a building block for network anomaly detection and traffic measurement in large computer networks.

Abstract: A method and system use an alternative sensor signal received from a sensor other than an air conduction microphone to estimate a clean speech value. The estimation uses either the alternative sensor signal alone, or in conjunction with the air conduction microphone signal. The clean speech value is estimated without using a model trained from noisy training data collected from an air conduction microphone. Under one embodiment, correction vectors are added to a vector formed from the alternative sensor signal in order to form a filter, which is applied to the air conductive microphone signal to produce the clean speech estimate. In other embodiments, the pitch of a speech signal is determined from the alternative sensor signal and is used to decompose an air conduction microphone signal. The decomposed signal is then used to determine a clean signal estimate.
