Granted: 2001-01-30
Abstract: L'invention concerne un système de traitement entièrement optique pour connecter ou convertir des signaux optiques d'une forme multiplexée par répartition en longueur d'onde (WDM) à une forme multiplexée par répartition temporelle optique (OTDM), où le signal WDM initial présente généralement une structure de signalisation sans retour à zéro (NRZ). Le système comporte une pluralité de canaux WDM optiques permanents modulés par des données NRZ (w, x, y, z), qui sont modulés en phase croisée, et sont ainsi spectralement élargis, dans un élément optique non linéaire (745), par un signal d'impulsion d'horloge puissant. Le signal résultant comporte une représentation RZ du signal NRZ original. Le signal RZ est temporellement décalé par un élément de dispersion (760), lequel décale temporellement d'une valeur prédéterminée chaque canal de longueur d'onde, pour produire un signal OTDM à longueurs d'onde entrelacées. Ce signal est ensuite converti en longueur d'onde par modulation en phase croisée avec un faisceau de commande permanent dans un deuxième élément optique non linéaire (770), pour donner un signal OTDM à une seule longueur d'onde.

Patent CA-2205752-C (CA)
Inventor: VOSS DON
IPC: A01F15/10
Filed: 1997-05-21
Granted: 2001-04-17
Abstract: The invention provides an improvement to the feed path for conventional belt round balers in the agricultural industry, and reduces the jamming of baling material in the feed gap of the baler. In a commonly known round baler the baling material enters the bale forming chamber through a feed gap defined by an upper roller and rotating away from the bale forming chamber, and a lower roller and rotating towards the bale forming chamber. As the upper roller is moving counter to the flow of baling material into the bale forming chamber, baling material which contacts them is retarded, and tends to form a ball of material which can plug the feed gap. The present invention provides a plate covering the upper roller which plate deflects the baling material into the feed gap and prevents the baling material from contacting the upper roller. The invention could be provided as an integral flange manufactured in new balers, or could be produced as a mountable plate for retrofitting of existing equipment.

Abstract: The matrix of the composite material is made in sequenced manner by chemical vapor infiltration within fiber reinforcement. Each elementary sequence of the matrix comprises a relatively flexible layer and a relatively rigid ceramic layer, and the sequences are of thicknesses that increase going away from the reinforcing fibers, with the thickness at least of the first-deposited sequence being selected to be sufficiently small for the fibers to be coated in essentially individual manner. The flexible layers are made of an anisotropic material having sufficient capacity for elastic deformation in shear and transversely, and although a mainly ceramic character is conserved for the matrix, the thickness of the flexible layers is nevertheless selected to be sufficiently large to be capable of absorbing differential expansion of the components of the composite material while it is being made without inducing the existence of an initial network of cracks.

Title: Instrument for compensating for hand tremor during the manipulation of fine structures
Inventor: PEER FERDINAND
IPC: A61B90/50
Filed: 1998-01-07
Granted: 2006-03-28
Abstract: The invention relates to an instrument for the manipulation of fine structures, said instrument detecting hand tremor and compensating for this hand tremor by effecting counter-movements of the working tip.      The main area of application will probably lie in the field of microsurgery, since the operations performed in said field can be made difficult by the hand tremor of the operating surgeon. Here, the tremor is detected by movement sensors, by repeated analysis of the position of the handheld part (1) of the instrument, or by deriving electromyographie signals from the forearm of the operator. Intentional and unintentional movements are differentiated from one another on the basis of one or more criteria, such as movement amplitude, speed, frequency and direction. To compensate for undesired movements, signals are sent to an arrangement of actuators (3) which cause deflections of the movable part (4) of the instrument, which deflections at the tip of the instrument compensate for the hand tremor. When the instrument is used as a needle holder in surgery, the actuators (3) can also be controlled by push button in such a way that, by oscillations, they facilitate the penetration of the suture needle into the area being worked on.

Abstract: An implantable antitachyarrhythmia device having the capability of detecting multiple tachyarrhythmias, such as ventricular tachycardia and ventricular fibrillation and capable of delivering multiple therapies, such as antitachycardis pacing, cardioversion and defibrillation, In order to assist the physician in understanding the progress of the device toward detecting a tachyarrhythmia and to better understand the operation of the therapy provided by the device, the device transmits information related to these functions on a beat by beat basis, as a supplement to markers signals associated with paced and sensed heart events. The information telemetry regarding detection allows the physician to determine how the particular R-R interval preceding the telemetry has affected the internal counts or order diagnostic parameters required to accomplish tachyarrhythmia detection. Similarly, in conjuction with stimulus pulses, the device transmits information indicative of which of the available therapy regiments is presently in effect.

Abstract: The present invention discloses a hydrofining catalyst. The catalyst has the following composition based on the total weight of the entire catalyst composition: 1-5 % (wt.) nickel oxide, 12-35 % (wt.) tungsten oxide, 1-9 % (wt.) fluorine, and the balancing amount of composite alumina. Said composite alumina is composed of one or several kinds of micropore alumina and one or several kinds of macropore alumina, wherein the weight ratio of micropore alumina to macropore alumina is 75:25 to 50:50. The term "micropore alumina" in the context means the alumina in which the volume of the pore of diameter less than 80 angstrom occupies more than 95 % of its total pore volume, while the term "macropore alumina" in the context means the alumina in which the volume of the pore of diameter 60-600 angstrom occupies more that 70 % of its total pore volume. The pore distribution mentioned above is determined by BET method of nitrogen adsorption at low temperature. This catalyst is especially suitable for the hydrofining of inferior distillates with high sulfure content and boiling range of 80-550 °C.
