Abstract: 12 Procédé de formation de voies pour sonar, notamment pour sonar remorqué Dans un procédé de formation de voies pour sonar après avoir échantillonné à une fréquence T = 1/4fo (fo fréquence de réception centrale du sonar) les signaux des hydrophones (1-N) du sonar et les avoir transposés en bande de base, on sous-échantillonne les signaux ainsi transposés avec une période TSE = kT (k entier) sensiblement égale à 1,25 B où B est la bande de fréquence de réception du sonar. Un premier ensemble de signaux est sous-échantillonné à des instants identiques pour former un secteur frontal (S1). Deux autres ensembles de signaux sont sous-échantillonnés avec des retards entre les signaux de deux hydrophones adjacents égaux à T, ce qui détermine deux secteurs latéraux (S2, S3) adjacents au secteur frontal. Ces signaux sous-échantillonnés sont ensuite transmis en série par le câble de remorquage (30) de l'antenne du sonar et sont traités (60) dans des circuits FFT qui permettent de former dans chaque secteur un ensemble de voies couvrant ce secteur. Ceci permet de diminuer considérablement le débit des données entre la partie du sonar remorquée et la partie du sonar située dans le bateau.

Title: Gas distributor and heater for spray drying
Inventor: BRO KLAUS
IPC: F26B17/10
Filed: 1990-09-25
Abstract: ABSTRACT OF THE DISCLOSURE    A gas distributor and heating device for a spray dryer which includes  a  feed  liquid  atomizer  in a drying  chamber,  a  gas distributor for supplying a uniform flow of gas, a guide duct for conveying the flow of gas from the gas distributor and to an outlet providing a flow of processing or drying gas to contact liquid droplets dispersed by the atomizer.  A gas heater is located in the device between the gas distributor and the guide duct outlet to heat the gas just prior to its introduction into the spray chamber.          This provides a high temperature drying gas close to the atomizer and avoids problems encountered in attempting to transfer a gas that has been heated at a location remote from the spray chamber.          A guide duct in the form of an annular guide duct provides an annular flow of heated gas concentric with the atomizer.  A gas burner extends circumferentially around the interior of the guide duct and is disposed to emit the gases of combustion in the direction of the outlet.  The guide duct may also include a plate shielding a portion of the gas flow from direct contact with the burner and the gases of combustion to provide an insulating flow of gas between the annular duct and the combustion  zone.

Title: System for scanning and reading symbols, such as bar codes, which is adapted to be configured in a hand held unit and can automatically read symbols on objects which are placed inthe detection zone of the unit
Inventor: EASTMAN JAY M
IPC: G02B26/10
Filed: 1991-12-03
Abstract: SYSTEM FOR SCANNING AND READING SYMBOLS, SUCH AS BAR CODES, WHICH IS ADAPTED TO BE CONFIGURED IN A HAND HELD UNIT AND CAN AUTOMATICALLY      READ SYMBOLS ON OBJECTS WHICH ARE PLACED      IN THE DETECTION ZONE OF THE UNIT                         ABSTRACT          A unitary hand-held bar code scanner and reader produces an elliptical beam, oriented with its major axis along the direction of the bars, utilizing optics employing far field diffraction effects to shape the beam and maintain its elliptical aspect (length to width ratio) constant over a distance in front of the scanner were bar codes may be located.  The optics eliminates parallax even though the photodetector and light source (preferably a laser diode) are located offset from each other on a board on which the optics are mounted.  A housing assembly has channels which mount the board therein without shock absorbing devices.  A digital microcomputer controller and peripheral devices regulate the optical power output from the laser diode and prevents catastrophic failure, if the electrical current through the laser diode exceeds safe limits.  Digital control of the gain of the electronic circuits which provide the signals from which bar code information can be decoded and for the operation and control of a motor for oscillating a deflector which scans the beam across the code are also provided utilizing the microcomputer.  The microcomputer also controls interface circuits to provide compatibility with auxiliary equipment and host computers which generate commands and requires data inputs of various polarity and format.         When the scanner is mounted on an upright support which extends from a base of a stand, the ratio of the number of generated pulses to the reflected pulses is computed for a succession of pulses (ten pulses for example).  Then the presence of the label is detected and the system, implemented in an application program in the microprocessor controller of the bar code scanner initiates scanning of the bar code when the ratio differs from a certain value.  Upon the detection of the code (a good read) or under conditions where the label is removed before detection, or is not removed after detection, the scanning mode is discontinued and the pulsing mode is again initiated.  The pulsing mode is initiated continually to test for the presence of a object carrying a bar code label, when not scanning.
