Patent CA-2187639-A1 (CA)
Title: Computer system and computer-implemented process for phonology-based automatic speech recognition
Inventor: KAYE JONATHAN
IPC: G10L25/93
Filed: 1995-04-11
Abstract: The present invention is based on the use of linguistic, especially phonological, knowledge to guide the speech recognition process. A speech signal containing an utterance is received and linguistic cues in the speech signal are detected. From these detected linguistic cues, a symbolic representation of the contents of the speech signal is generated. This symbolic representation comprises at least one word division, wherein each word division consists of an onset-rhyme pair and associated phonological elements. These phonological elements are univalent, may appear in all languages and are distinguishable from each other and directly interpretable in the speech signal. A lexicon of predetermined symbolic representations is provided for words in a particular language. A best match to the generated symbolic representation is found in the lexicon, thereby recognizing the spoken word.

IPC: B25B23/04
Filed: 1995-04-27
Abstract: A screw strip (1) is disclosed in which each screw (2) carries a washer (3) on its screw shank between the tip of the screw (2) and a plastic strip (1) carrying a plurality of screws. A screw driving apparatus (14), and method of use of the strip are also disclosed. The washers (3) and screw heads (4) are of relatively large diameter and adjacent washers (3) overlap each other. The power tools (13) used to install the screws include indexing means which advance successive screws into driving position, and retract the remaining screw strip rearwardly in order to avoid interference between the driving tool, the driven screw and adjacent washers. This configuration permits application of large head screws such as hexagonal head screws carrying large washers by power tool socket drivers and is particularly useful in sheet metal applications. The invention is applicable to any fastener with a threaded shank including bolts and screws.

Title: Apparatus for transferring containers to a moving conveyor
Inventor: PROCHUT RICHARD
IPC: B65G47/82
Filed: 1995-09-07
Abstract: A mechanism (10) is provided for simultaneously transferring a plurality of containers (14) onto a continuously moving conveyor (18) from a surface (22) located adjacent to the conveyor. A pair of pusher plates (34a, 34b) are positioned along the surface, opposite the conveyor. The pusher plates extend towards the conveyor to simultaneously transfer a predetermined number of containers onto the conveyor. A shuttle plate (60) is positioned above the conveyor and has compartments (68) positioned to receive the cartons as they are pushed onto the conveyor. The shuttle plate is then moved along the conveyor to accelerate the batch of containers up to the speed of the conveyor. Once the cartons reach the speed of the conveyor, the shuttle plate retracts out of the path of the conveyor and the containers continue to move along the conveyor. The shuttle plate then returns to its original to accept the next batch of containers.

Patent CA-2207587-A1 (CA)
Inventor: STATZ HERMANN
IPC: C08K7/18
Filed: 1995-11-17
Abstract: L'invention concerne des matières capables d'absorber le rayonnement, qui peuvent être utilisées dans la fabrication d'emballages, de feuilles, d'encres, de peintures, de produits de traitement de surfaces décoratives, de lotions, de crèmes et de gels. Ces matières font appel à certaines propriétés optiques que l'on trouve dans des particules uniformes, sphériques et de l'ordre du nanomètre et qui permettent une absorption totale du rayonnement, en une faible concentration, sur une largeur de bande donnée. Un type de particule présente, à une longueur d'onde donnée, une "arête d'absorption", qui permet la transmission d'un rayonnement dont la longueur d'onde dépasse celle d'une bande interdite caractéristique, tout en absorbant effectivement tout rayonnement dont la longueur d'onde est inférieure à ce minimum. Un autre type de particule présente une "résonance optique" qui entraîne l'interaction d'un rayonnement d'une longueur d'onde caractéristique avec les particules de façon à produire des réflexions internes à renforcemement autonome, ce qui augmente nettement l'amplitude du rayonnement piégé dans la particule.
Patent CA-2208248-A1 (CA)
Inventor: HOVINGA ROBERT PAUL
IPC: F16L1/26
Filed: 1996-10-24
Abstract: The invention relates to a method for assembling and disassembling an installation present on a seabed, for instance a pipeline lying on a seabed, wherein components, for instance pipe flanges, are mutually attached by means of nut and bolt connections and the nut and bolt connections are released and/or secured by means of a wrench. Nut and bolt connections are herein released by divers using a wrench. This is heavy and difficult work. It is impossible for divers to operate at considerable depth. Complicated and very costly pipeline connections are then applied which can be released and secured without divers. The invention has for its object to reduce the stated drawbacks of the known method. To this end at least one wrench is used, of which an engagement cup for engaging a nut and/or a bolt head in axial direction of a nut and bolt connection for manipulating is displaceable relative to a cup carrier counter to spring action.
