  • Patent number: 4513435
    Abstract: A system for recognizing a continuously spoken word sequence with reference to preselected reference words with the problem of coarticulation removed, comprises a pattern memory for memorizing demi-word pair reference patterns consisting of a former and a latter reference pattern segment for each reference word and a word pair reference pattern segment for each permutation with repetition of two words selected from the preselected reference words. A recognition unit is operable as a finite-state automaton on concatenating the demi-word pair reference patterns so that no contradiction occurs at each interface of the reference patterns in every concatenation. It is possible to use the automaton in restricting the number of reference patterns in each concatenation either to an odd or an even positive integer.

  • Patent number: 4454482
    Abstract: The apparatus comprises a source capable of producing an atomic (molecular) beam and at least one electromagnetic resonator of the open type through which the atoms (molecules) pass. Optical pumping means excite the atoms (molecules) of the beam into a selected energy level before the beam passes through the resonator. An electromagnetic field generator is connected to the resonator for generating inside said resonator a spatial distribution of electromagnetic field at a frequency corresponding to the difference between the energies associated to said first level or energetic state and a second level or energetic state of the atoms (molecules) in the beam. Detection means provide an electric signal indicative of the number of atoms (molecules) which inside the resonator undergo a transition to the above mentioned second level or energetic state.

  • Patent number: 4293945
    Abstract: A multichannel correlation receiver at an earth station is provided for determining the depolarization effects of atmospheric conditions on satellite communications. The receiver provides a first co-polarized signal and a second, relatively weak, cross-polarized signal indicative of the depolarization effects, and uses a phase locked loop demodulator to produce a noise free replica of the relatively strong co-polarized signal. This co-polarized signal is highly correlated with the second cross-polarized signal and is mixed therewith to provide a relatively noise free, narrow band signal which has a level indicative of the cross-polarization signal strength for both up-link and down-link propagation paths. The relative signal strengths are recorded on a digital storage means and provide an accurate measure of the depolarization effects of the existing atmospheric conditions. A programmable local oscillator also provides multiple channel capability.

  • Patent number: 4291647
    Abstract: The device comprises a syphon which connects a reservoir to a collecting recipient. The reservoir is supplied with liquid through a valve. A tube extends the reservoir upwardly and carries a detector which checks the level situated just above the syphon. A second detector is placed at the outlet of the syphon. The two detectors are electrically connected to the control of the valve so as to close the valve when the liquid reaches the detector checking the level and to preclude the opening of the valve so long as the detector receives liquid issuing from the syphon. The amount of liquid poured upon each opening of the valve is thus always strictly the same.Application to the preparation of mixtures having a precise and adjustable concentration, such as a mixture of powdered milk and water.

  • Patent number: 4291630
    Abstract: An extractor carriage is furnished on each side with an elbow bracket projecting towards its lower portion. To each of these brackets is attached the end of a cable which moves the carriage in its forward direction towards the centrifuging machine. Each cable is protected at its upper portion from sand debris by lateral wings extending from the upper portions of a trough which receives the debris. These cables, as well as a third cable for returning the carriage, are wound around a single motor drum driven by hydraulic motors which are capable of operating at several speeds. The invention may be applied to centrifuging equipment for cast iron pipe.
