Title: Device for localising a vehicle moving along electromagnetic waves propagation means
Inventor: FOURNIER DENIS
IPC: G01S13/93
Filed: 1996-02-19
Granted: 2006-12-19
Abstract: The system for locating a railway vehicle (V) in relation to a fixed wave propagating rail (P) includes a circuit (E) placed on the vehicle and transmitting electromagnetic waves (Ee). The waves are reflected (Er) at a fixed position (R') in the rail and received (R) on board of the vehicle. A comparison circuit (C) compares the transmitted waves with the reflected waves. A processing circuit analyses the difference between the two signals in order to determine the distance travelled by the reflected wave, and hence the distance of the vehicle from the fixed reflector position.

Granted: 2000-07-18
Abstract: A method and apparatus is disclosed which reduces or removes axial loads on the drive string of a rotary downhole pump, i.e. tensile loads due to the hydrostatic load of the pumped liquid on the pump rotor, and/or at least part of the weight of the drive string, or thrust loads caused during pressurized fluid injection operations by backpressure of injected fluid on the pump rotor. This substantially prevents drive string/production tubing friction, wear and/or buckle in downhole rotary pumpingarrangements operated in straight or curved well bores. When used in connection with fluid production pumping arrangements, the apparatus reduces the friction between the drive string and the production tubing of a downhole rotary pump for the pumping of well fluids which pump has a pump rotor connected to the drive string and is operated in a well bore. When used in connection with fluid injection pumping arrangements, the apparatus prevents drive string buckle, especially in curved well bore situations. The apparatus includes a support for rotatably supporting the drive string in the production tubing at a location above the pump, and a fluid passage for permitting the pumped fluid to flow from the pump to a wellhead of the well. The support includes an axial load bearing structure for supporting, from the production tubing, at least part of an axial load on the drive string either generated by the hydrostatic load of a pumped liquid on the pump rotor or backpressure of injected fluid on the pump rotor. The fluid passage is shaped and constructed such that the pumped fluid can flow from the pump past the axial load bearing means to the wellhead. In fluid pumping applications, the apparatus can also be used to support at least part of the weight of the drive string to reduce the axial load on the drivehead.

Abstract: On effectue l'étalonnage d'un mécanisme (104) de régulation de longueurs d'onde d'un laser au moyen d'une lampe d'absorption cathodique creuse (114). La lampe renferme une substance à l'état de vapeur ayant une longueur d'onde d'absorption maximum connue avec précision. C'est en fonction de la longueur d'onde qu'un photodétecteur (130) détecte la quantité de lumière provenant du faisceau laser absorbé par la substance à l'état de vapeur. On régule la longueur d'onde du laser afin d'obtenir une absorption maximum de sorte que la longueur d'onde réelle du faisceau laser peut être comparée à une longueur d'onde estimée permettant de déterminer un décalage d'étalonnage. La lampe cathodique creuse (114), en fonctionnement, génère une substance à l'état de vapeur ayant une caractéristique d'absorption connue, mais son niveau d'éclairage est sensiblement inférieur à un niveau normalement requis auquel se produit une résonance opto-galvanique classique.

Abstract: A sheet separating and feeding device for use as a component of a sheet processing apparatus is disclosed in which a first feeding device acts on the top of a stack of sheets to feed the top sheet toward a take away feeder for removal from the stack, during which a retaining device applies a force to the upper surface of the exposed trailing edge portion of the next to top sheet to apply a retaining force thereto and to the rest of the stack, and simultaneously lifts the first feeding device off of the top sheet to remove thenormal force from the weight of this device from the stack. When the top sheet is entirely removed from the stack, the first feeding device is lowered toengage the new top sheet and the retaining force is removed therefrom so that it can now be fed to the take away feeder.

Abstract: Disclosed is a polycondensation reactor for polyesters, polyamides or polyarylates in which a low I.V. material is introduced into the reactor and a relative high I.V. polymer exits the reactor. The reactor has at least two overlapping cyclindrical interior chambers, each with a rotating shaft through its length. Each shaft has a plurality of stirrers and spacers designed to wipe all interior surfaces of the reactor. The stirrers can be shaped as a cycloid or involute profile, for example. Generally the stirrers on each shaft are indexed from one another preferably by 90° and interdigitate with stirrers on the adjacent shaft.      Stirring the low I.V. material by rotating the stirrers (on the shafts) through the material spreads it into a plurality of thin films. At the temperature and vacuum conditions of the reactor, a volatile component is removed, thus causing the material to polymerize, by condensation, forming a relatively high I.V. polymer.

Abstract: Image compression and viewing are implemented. A DWT-based compression method uses a two-level memory computer. The viewing method selects image areas in compressed form at multiple resolutions. For compression, a plurality of discrete tile image subsets (118) is defined which form the complete image. Seamless wavelet--based image compression occurs by in-putting the tiles in a selected sequence to a DWT (120) routine. The resulting DWT coefficients are stored in a first primary memory and periodically are compressed (128) and stored in a secondary memory (124). The sequence of DWT operations on the tiles effectively calculates a seamless DWT of the image. Data retrieval occurs by specifying a resolution and a region of the image for display (146). The subset of stored DWT coefficients corresponding to each requested scene is determined and then decompressed for input to an inverse DWT (164) to form the display (166). Interaction (168) may occur with a pointing device on previous retrieved displays.

Title: Large round baler net wrapping device for dispensing net from a supply  roll resting on driven feed roll
Inventor: MASS NISSIM
IPC: A01F15/07
Filed: 1998-09-03
Granted: 2002-01-15
Abstract: A large round baler is equipped with a wrapping device for wrapping a bale with a web of plastic net wrapping material. The device includes a pair of wrap material feed rolls arranged one above the other with a supply roll of wrapping material being directly supported by the upper feed roll so that during operation of the feed rolls in dispensing a length of wrap material being wrapped about a bale, the periphery of the supply roll is rotated at the same speed as the periphery of the upper feed roll so that no scrubbing takes place between the supply and feed rolls. A pressure applying device uses a pair of air or gas cylinders acting through a linkage to force a free rotating roller to exert a force on the supply roll which is transferred through the roll to the feed roll. In this way variable friction forces are avoided which would interfere with the maintenance of a desired constant tension in the length of wrapping material so that the bale is wrapped tightly, but without rupturing the net material.

Abstract: An automated design process and apparatus for use in designing complex structures, such as circuits, to satisfy prespecified design goals (1008-1016), using genetic operations (1046). The present invention uses a population of entities (1022) which may be evolved to generate structures (1024-1028) that may potentially satisfy the design goals (1008-1016). The behavior of such generated structure is evaluated (1008) in view of the design goals, and those structures more closely meeting the design goals are evolved further (1020-1044) until a structure is generated that either meets the prespecified design goal (1010-1016) or some other process completion criteria (1046).     In this manner, a design complex structure may be obtained.
