Title: Method and apparatus for speech synthesis
Inventor: HUTCHINS SANDRA E
IPC: G10L13/08
Filed: 1993-09-23
Abstract: A system for synthesizing a speech signal from strings of words (1005) includes a memory (1010) in which predeter-mined syntax tags are stored in association with entered words and phonetic transcriptions are stored in association with the syntax tags. A parser (1040) accesses the memory and groups the syntax tags into phrases according to a first set of predetermined grammatical rules relating the syntax tags to one another. The parser also verifies the conformance of sequences of the phrases to a second set of rules relating phrases to one another. The system retrieves the phonetic transcription associated with the syntax tags (1080) and adds markers for rhythm and stress to the strings, which are then converted into data arrays (1110) having prosody informa-tion on a diphone-by-diphone basis. Diphone waveforms are retrieved from memory (1130) and adjusted based on the prosody information in the arrays (1120). The adjusted di-phone waveforms are then concatenated to form the speech signal.

Title: Generating imitation custom artwork by simulating brush strokes and enhancing edges
Inventor: MIZUTANI MASAO
IPC: G06T1/00
Filed: 1995-04-10
Abstract: The precision of an initial image is reduced through image automatic processing in a manner simulating techniques used in the production of a custom art work. The resulting image, although generated without human intervention, has a pleasing, customized appearance which can be desirable to consumers seeking decorative art work.  One way of reducing the precision of the initial image is modifying portions of the image to have more uniform luminance, color saturation, or color hue, producing a resulting image appearing to contain brush strokes. Alternatively, the precision of the initial image is reduced by locating contrast edges in the image, and modifying the luminance along these edges, producing a resulting image in which objects and features are outlined and have an enhanced definition from the background.

Patent CA-2165115-A1 (CA)
Title: Downspout extention device
Inventor: MC CAUGHAN BRIAN
IPC: E04D13/08
Filed: 1995-12-13
Abstract: Without a downspout extension rain water collected on the roof of a building is spilled onto the ground beside the foundation.   This causes damp and musky basements and sometimes even cracked foundations.   The problem with using a downspout extension is that it must be walked over; additionally it must be removed and re-installed in order to cut a lawn thereunder.   The automatic extension device disclosed utilizes a rocker arm having a cup on one end and a hook/ latch on the other.   An upright tubular member having an upper end portion adapted to slide over the downspout and a lower end portion which elbows outwardly away from an adjacent building wall has an extension tube pivotably connected thereto.   A channel extending laterally and downwardly from inside the upright tubular member to above the cup diverts rain water from the downspout into the cup.   The extension tube is stored in an upright position having one end held up by the hook/ latch.   At the onset of a rain storm the cup is filled, and the rocker arm rotates lifting up the hook/ latch; this causes the extension to automatically fall into an operable position.   The extension may be rotatably lifted for lawn maintenance into its storeage position where it is maintained by the hook/ latch.

Inventor: BUNKER NORMAN S
IPC: H04N5/21
Filed: 1994-04-08
Abstract: Lorsqu'on traite une information vidéo pour télévision, la bande à fréquence basse est d'un très grand intérêt à cause des propriétés naturelles de pondération de l'oeil humain, et à cause de la réponse limitée en fréquence d'éléments de visualisation vidéo tels que les écrans de visualisation phosphorescents et à cristaux liquides. Un bruit est produit et observé dans la région basse fréquence des signaux vidéo analogiques numérisés à cause de la mauvaise linéarité inhérente au procédé de numérisation. Grâce à l'invention, on diminue le bruit mesuré dans la région basse fréquence par décalage vers le haut de la bande et hors des fréquences utiles en ajoutant un signal de tremblement au signal d'entrée analogique et en utilisant un filtre numérique de décimation 2X pour enlever les signaux indésirables de tremblement et les signaux d'intermodulation parasites. L'invention décrite permet d'avoir un moyen simple et bon marché pour éliminer les signaux de tremblement sans avoir à recourir aux techniques complexes de soustraction du signal de tremblement utilisées dans l'art antérieur.

Abstract: A radiator tube (10) which has pairs of opposed turbulator dimples (20) formed in its principal heat transfer surfaces (12, 14), which dimples extend inwardly and meet in the tube interior to define a plurality of pillars. First and second generally continuous curved surfaces (16, 18) interconnect and are integrally formed with the principal heat transfer surfaces (12, 14). In a method of forming a radiator tube (10) having a flattened oval shape, turbulator dimples (20) are formed in agenerally planar metal strip (30) in a pattern which is symmetric about a longitudinal line (36). The strip (30) is roll formed into tubing (50) having a circular cross-section with its opposed side edges (32) abutting and in alignment. The side edges (32) are simultaneously compressed and welded together by heating at the melting point of the parent metal using a high frequency induction current, to form a solderless joint (52) between them. Finally, the tubing (50) is transformed by reduction and breakdown rolls to a flattened oval cross-section. Apparatus for forming the tubing includes first and second modular cylindrical rolls (120, 122) mounted respectively on first and second parallel shafts (110, 112). The first roll (120) includes disks (152) with male punches (140) thereon, while the second roll (122) includes disks (152) with female dies or sections (142) formed therein in alignment with the male punches (140). The male punches (140) and female sections (142) are maintained in alignment by phasing gears (150) on the shafts (110, 112).

Filed: 1994-09-16
Abstract: On obtient de l'essence faiblement sulfurée à indice d'octane relativement élevé, à partir de naphtas de craquage oléfiniques contenant du soufre, par hydrodésulfurisation suivie d'un traitement à l'aide d'un catalysateur acide comprenant une zéolite béta et un composant d'hydrogénation métallique, de préférence un composant d'hydrogénation doux tel que le molybdène. Le traitement par catalyseur acide de la deuxième étape permet de compenser la diminution de l'indice d'octane se produisant lors du traitement hydrogénant et permet d'obtenir une essence faiblement sulfurée présentant un indice d'octane comparable à celui du naphta de base. Dans les cas favorables, en utilisant des produits de base à points terminaux étendus tels que les naphtas lourds avec 95 % de points au-dessus de 380 ~F (environ 193 ~C), on obtient une amélioration à la fois de l'indice d'octane du produit et du rendement par rapport aux produits de base.
