Patent CA-2285099-A1 (CA)
Inventor: HELBIG CLAUS
IPC: F16N11/08
Filed: 1999-10-06
Abstract: An automatic lubricant dispenser has a lower housing part formed with an outlet, a piston displaceable along an axis in the lower part and forming therein a compartment, a spindle extending along the axis, threaded into the piston, having an upper end above the piston provided with a lower coupling half, and a body of fluent lubricant filling the compartment. An upper housing part removably securable to the lower part holds an electrical motor unit having an output shaft projecting downward at the axis and provided with an upper coupling half axially engageable with the lower coupling half. The coupling halves are axially engageable to rotationally couple the motor output shaft to the spindle so that electrical energization of the motor when the coupling halves are engaged displaces the piston and expresses lubricant from the outlet. A sensor connected to the shaft generates an output after a predetermined angular displacement of the shaft. An erasable nonvolatile memory in the upper housing part is associated with a reset switch for clearing the nonvolatile memory and with electrically powered controller.      This controller is also connected to the sensor means and nonvolatile memory for periodically energizing the motor, for storing in the nonvolatile memory information about elapsed time since last energization of the motor and the number of outputs emitted by the sensor means, and for reading the information stored in the memory.

Filed: 2000-02-16
Abstract: Disclosed is a video recording apparatus capable of performing long-recording at higher density and certainly associating the video data with additional data. Video images from a plurality of video cameras 101 are captured by a multiplexer 103 while sequentially being switched. A frame compositing unit 1 forms reduced video images by reducing the captured video images and generates a composite video image by displaying the reduced video images on divided parts. A CPU 3 generates additional data related to the reduced video image on each divided part and records the composite video image and additional data onto the same video cassette tape 7 while maintaining the correspondence between each reduced video image and additional data. By recording video images from the plurality of video cameras at higher density, long-recording can be realized. By using the additional data, a desired reduced video image can be retrieved from the recorded composite video image and the retrieved reduced video image can be analyzed.
Patent CA-2300570-A1 (CA)
Inventor: BROWN DAVID A
IPC: B65B25/24
Filed: 2000-03-07
Abstract: A sleeving apparatus is used to place sleeves about looped belts. A belt manipulation apparatus receives a resilient belt to be sleeved in an undeformed condition. As the belt advances through the belt manipulation apparatus, it is squeezed to form a protruding bight, in the form of a tongue, that is of a size to slide into a rectangular opening or passage defined by the four walls of a sleeve. A  sleeve holder located adjacent to the belt manipulation apparatus maintains a sleeve in position to receive the belt to be sleeved. The belt manipulation apparatus urges or feeds the tongue forward into, and through the passage defined by the sleeve.  As the tongue extends beyond the exit of the sleeve, it seeks to resume its undeformed shape and consequently, it forms a bulge or loop of increasingly large dimensions.  When the belt is released from the belt manipulation apparatus and permitted to assume its position of lowest energy storage, a loop will have been formed at both ends of the belt and the mid-portion or waist of the belt will be constrained by the margins of the sleeve.

Patent CA-2305241-A1 (CA)
Inventor: SCHMIDT RAINER
IPC: H04R25/02
Filed: 1999-07-16
Abstract: In order to carry out an otoplasty for IO- and HdO-type audio prostheses or for a nose adjustment part, a hollow body in the shape of a truncated cone is provided that tapers towards the proximal end and that comprises a peripheral wall (12) made of a plastic light-curable material capable of deformation. The peripheral wall (12) is connected at its distal end by a removable closure plate (20) providing a tight seal. A flexible tube (22) extends inside the tightly sealed hollow body (10). After insertion of the hollow body into the ear, the flexible tube is used for inflating said hollow body until the peripheral wall (12) tightly conforms the surface of the auditory canal. At this step, the peripheral wall is at least partially reinforced by the action of light so that the hollow body (10) keeps its expanded shape even after eliminating the inner over-pressure. The closure plate (20) is then removed and the peripheral wall (12) is optionally permanently cured. The otoplasty thus obtained is used for receiving a auditory prosthesis module which is placed within the ear and which comprises a base plate that can be clipped onto the outer ring (18) of the peripheral wall (12). This method can be used for producing audio prostheses with a rapid and very precise individual adaptation of the otoplasty during a single session.

Title: Pilot control valve for controlling a reciprocating pump
Inventor: ELLIOTT ANDREW C
IPC: F01L25/06
Filed: 2000-06-02
Abstract: A pilot control valve for controlling a reciprocating pump having a valve member shiftable within a valve body between a first or "downstroke" position and a second or "upstroke" position. When the valve member is in its first position, the valve member allows communication of control fluid to the lower surface of a piston to move the piston from a first position to a second position. As the piston reaches its second position, a vent in a rod attached to the piston allows control fluid acting on the valve member to depressurize.  As such control fluid is depressurized, pressurized control fluid acts on the valve member to move the valve member from its first position to its second position. In its second position, the valve member blocks communication of the control fluid to the lower surface of the piston and allows communication of the control fluid to the upper surface of the piston causing the piston to return to its first position. As the piston returns to its first position, the vent in the piston rod allows the pressurized control fluid acting on the upper surface of the piston to act on the valve member to move the valve member back to its first position. In its first position, the valve member blocks communication of the control fluid to the upper surface of the piston and allows communication of the control fluid to the lower surface of the piston and the process is repeated In this manner, the pilot control valve of the present invention achieves a consistent pumping rate for a reciprocating device coupled to the pilot control valve.

Title: A circulating sub apparatus and method
Inventor: KAMINSKI LEONARD ANTHONY
IPC: E21B21/10
Filed: 2000-06-09
Abstract: "A Circulating Sub Apparatus and Method" A circulating sub apparatus and method is described. The apparatus has an outer body member and an inner body member each having one or more holes, and a displacement mechanism for producing relative movement between the outer body member and the inner body member. The inner body member and the outer body member may be moved between a first configuration, in which the one or more holes on the inner body member are substantially in fluid communication with the one or more holes on the outer body member, and a second configuration, in which fluid communication between the one or more holes on the inner body member and those on the outer body member is substantially prevented. The apparatus is arranged such that when the inner and outer body members are in the first configuration, fluid need not flow through the displacement mechanism. A restraint device for restraining movement of the inner body member with respect to the outer body member is also described, wherein the restraint device is disposed within a chamber which is isolated from fluid located outwith the chamber.

Title: An amplifier and a method of power amplification
Inventor: VAKTNAS CHRISTER
IPC: H03F1/32
Filed: 1998-11-10
Abstract: The present invention relates to a power amplifier and to a method of amplifying in the power amplifier a first composite radio signal that includes at least two modulated carrier waves. The first radio signal is divided into two radio signals, which are amplified in a first and a second non-linear amplifier. Intermodulation products arise in the amplification of said radio signals in respective amplifiers. A compensation signal is generated from the output signal of the second amplifier, and the modulated carrier waves are suppressed selectively, e.g. by filtering out the carrier waves in band-stop filters. An output signal from the power amplifier is generated by reverse phase addition of the compensation signal to the output signal from the first amplifier.

IPC: H04B7/005
Filed: 1998-11-20
Abstract: L'invention concerne un procédé de calcul de puissance au moyen d'une logique AMCR à séquence directe utilisant une détection non cohérente. Pour faire un calcul précis de la puissance, on met les amplitudes complexes du canal en mémoire tampon, et on calcule de manière cohérente la moyenne des amplitudes complexes récupérées, ceci, après détection non cohérente d'un symbole reçu. Pour obtenir une mesure encore plus précise, on effectue un nouveau calcul de la fréquence Doppler selon une autre réalisation. L'amplitude du canal peut être considérée comme constante sur une période plus longue que celle d'un simple symbole, le calcul cohérent de la moyenne générant des mesures de puissance plus précises que celles obtenues par le calcul non cohérent de la moyenne. Pour obtenir une mesure encore plus précise, on calcule la fréquence Doppler et la moyenne uniquement de manière cohérente sur une période ne dépassant pas la période de cohérence. En faisant baisser la variance des résultats obtenus, on limite de plus en plus l'effet de la polarisation.

Filed: 1999-02-04
Abstract: Cette invention a trait à une technique permettant de concentrer une protéine à conformation liée à une affection, notamment le prion Sc (PrP?Sc¿) présent dans un prélèvement. Cette technique consiste à liquéfier le prélèvement et à y ajouter un agent de complexion, un acide phosphotungstique (PTA), formant, de manière préférentielle ou exclusive, un complexe avec le PrP?Sc¿. Une fois le complexe formé, on soumet la composition à une centrifugation jusqu'à ce que le complexe occupe le fond du contenant. Après cela, on évacue le liquide surnageant. Le sédiment restant peut être remis en suspension dans une solution aqueuse contenant un inhibiteur de protéase aux fins du stockage. Le PTA colore le PrP?Sc¿ faisant mieux se prêter le PrP?Sc¿ concentré résultant à une analyse ultérieure et rendant possible une détermination rapide et efficace de la présence du PrP?Sc¿ et de sa concentration dans le prélèvement. Il est également possible d'utiliser cette technique pour rendre un prélèvement non infectieux et ce, en éliminant toute forme infectieuse ou une grande partie de celle-ci d'une protéine dans un prélèvement.
