The invention is a method and apparatus, automatic down hole blow out preventer wherein external elastomer rings are placed on the exterior of a grooved section of drill pipe. Below the external elastomer rings is an external pressure deflector ring, which is designed to be lifted up in a kick. When a kick occurs, the increased pressure will force the external pressure deflector ring up, causing the external elastomer rings to flip up and out as to inhibit or block the further flow of fluid up the annulus.

In the method according to the invention for separating mercury from waste gases of a cement production process, the mercury is sorbed on a sorbent, the sorbent is subsequently discharged from the process and supplied to a discharge reactor which is operated with a carrier gas. The sorbent is heated there to temperatures of more than 250° C. so that the mercury is discharged from the sorbent and changed into the gas phase, the gas of the discharge reactor that has accumulated mercury subsequently having the dust removed from it in a preliminary dust removal device, and only a part-flow of the gas which has been enriched and had the dust removed from it in this manner being drawn off at high temperatures and cleaned in a subsequent sorption stage, whilst the remaining part-flow is brought to the temperature required for the discharge of the mercury in the discharge reactor in a heat transfer system and is again supplied as a carrier gas to the discharge reactor.

In accordance with an embodiment the invention, there is a device manufacturing method. The method can comprise providing a substrate comprising a radiation-sensitive material disposed thereon and directing a beam of radiation through an aperture such that the radiation produces at least two illumination poles. The method can also comprise exposing the substrate to the at least two illumination poles using off-axis illumination and varying a size of a first illumination pole of the at least two illumination poles with respect to a second illumination pole of the at least two illumination poles.

A computer-based method and apparatus for classifying statement types using intonation analysis. The method and apparatus identify a user's potential query when the user responds to information during dialog with an automated dialog system. Pitch information is extracted, via a cepstrum, from the speech signal. In one embodiment, the pitch intonation is processed to form a smoothed pitch or intonation contour. Then the smoothed pitch contour is processed by a set of shape detectors and this output, together with statistical information, is sent to a rule-based algorithm which attempts to classify the statement type. In another embodiment, the smoothed pitch contour is processed by a pattern recognition system such as a neural network trained with a back-propagation learning algorithm.

A method and apparatus for enhancing the intelligibility of a telephonic speech signal within the available bandwidth and intensity limits of a telephone communication network. The method combines enhancement of both the formant ratio and the consonant/vowel energy ratio to realize a speech signal more intelligible to a hearing impaired user. The invention uses an auditory model of the human ear. A speech signal is put through a filter bank designed to simulate the cochlear filter shapes and filter spacing of a healthy cochlea. The energy output from each of a plurality of filters is computed and used to form an auditory spectrum. The peaks associated with strong first and second formants are identified, and the second formant is enhanced relative to the first formant by attenuating the first formant. Also, consonants in the speech signal are identified as having an energy level below a threshold associated with vowels, but above the threshold associated with silent regions. Consonant regions are amplified. The net effect is to provide more energy in regions of the second formant and the consonants to enhance the intelligibility of the speech signal.

A holder for a guitar slide bar wherein the slide bar may be conveniently stored by the musician on the guitar strap, the holder eliminating the necessity to search for the slide bar when needed. The slide bar holder consists of a U-shaped body which is clipped upon the guitar strap and a portion of the body supports the slide bar retaining apparatus, which may either be in the form of resilient clips, or magnets, if a ferrous slide is employed.
