Title: Printhead installation and retaining mechanism
Inventor: BLUM JOHN N
IPC: B41J2/03
Filed: 1999-12-10
Abstract: In an ink jet printer having a printhead and a printhead docking station, an improvement is provided in installation and retention of the printhead in the printhead docking station.      Straight line travel of the printhead relative to the printhead docking station is ensured using guide posts or other guiding mechanisms. Non-abrupt actuation, such as a screw drive actuator is used to translate the printhead relative to the docking station. The screw drive actuator is oriented at near right angles to the direction of translation of the printhead relative to the printhead docking station. The printhead and the printhead docking station are then aligned so that electrical and fluid connections can be made concurrently. During the installation, a consistent insertion force, such as a spring loaded toggle mechanism, is applied to the printhead, regardless of part tolerances.

Title: Procede automatise a haut debit permettant de cribler une pluralite de composes par spectrometrie de masse
Inventor: KYRANOS JAMES N
IPC: C40B60/14
Filed: 1998-06-03
Abstract: L'invention concerne un procédé qui permet de tester rapidement une pluralité de composés à la recherche d'une interaction non covalente avec au moins une cible. Le procédé comprend les étapes suivantes: on introduit un flux continu constitué d'une phase mobile dans un spectromètre de masse; on règle les paramètres dudit spectromètre de façon à détecter au moins une cible contenue dans la phase mobile; on injecte progressivement dans ladite phase mobile différents échantillons d'une pluralité de mélanges, chaque mélange comprenant au moins la cible et au moins un composé d'intérêt, de façon à les faire passer dans le spectromètre; et on obtient un spectre de masse qui indique pour chaque mélange la présence ou l'absence d'un complexe constitué de la cible et du composé d'intérêt. De préférence, on injecte la totalité de chaque échantillon dans la phase mobile en moins de 5 minutes, encore mieux en moins d'une minute et idéalement en moins de 30 secondes. On peut multiplexer le procédé de l'invention en constituant un mélange qui contient une seule cible et une pluralité de composés d'intérêt, ou bien un seul composé d'intérêt et une pluralité de cibles de protéines récepteurs ou de complexes récepteur-ligand. Typiquement, on forme la pluralité de mélanges au niveau d'une pluralité de sites adressables, tels que les puits d'une plaque multipuits. On retire les échantillons de mélanges des sites adressables, puis on les injecte progressivement dans la phase mobile de façon à les amener au spectromètre de masse. On peut également déterminer la force relative de l'interaction entre la cible et le composé d'intérêt au sein de chaque complexe en dissociant au moins un complexe constitué d'une cible et d'un composé d'intérêt.

An inductive coil assembly for this purpose comprises a copper tubular combined electrical current conductor and conduit for circulating cooling water having a first closed end and a second end connectable to a source of cooling fluid and a source of electricity. At least one, and preferably a plurality, of copper noses extend outwardly from the combined conductor and conduit and both conduct electricity and circulate cooling fluid. The noses extend substantially perpendicularly to the combined conductor and conduit and are configured so as to effect proper induction heating of the panel. A magnetic flux concentrator is preferably provided over at least some of the noses. Preheating noses (e.g. solid copper blocks) may be connected to a leading portion of the combined conductor and conduit).

Patent CA-2308353-A1 (CA)
Title: Backpressure mechanism for a network device
Inventor: LADWIG GEOFFREY B
IPC: H04L12/56
Filed: 2000-05-12
Abstract: A method and apparatus are provided for scheduling multicast data in an input-queued network device. According to one aspect of the present invention, the head-of-line blocking problem is avoided for multicast queues. A fabric arbiter receives a transmit request associated with multiple input ports. The transmit request identifies those of the output ports to which pending multicast cells are ready to be transmitted, if any. The fabric arbiter receives a backpressure signal from a backpressuring output port. Then, based upon the backpressure signal the fabric arbiter schedules multicast cells for transmission across the fabric. If the size of a multicast queue exceeds a predetermined threshold, then the fabric arbiter ignores the backpressure signal and causes the head-of-line multicast cell from the multicast queue to be transferred to the backpressuring output port. Otherwise, the fabric arbiter prevents multicast cells from being transferred to the backpressuring output port by masking requests destined for the backpressuring output port thereby removing the backpressuring output port from consideration during multicast scheduling.

Title: Processing entailing sol-gel fabrication of silica glass
Inventor: BHANDARKAR SUHAS
IPC: C03B8/02
Filed: 2000-07-26
Abstract: Silica sots exhibiting desirable yield-dilatancy are fabricated. A mixture comprising silica, water, and a pH-adjusting agent is provided, and the mixture is shear-mixed. The desirable properties of the resultant sol are attained by using a concentration of pH-adjusting agent that provides a viscosity within a particular range during shear mixing.      The requisite pH range, however, changes depending on the properties of the silica mixture. A discovered technique for determining this changing pH range is by selecting the pH based on the silica surface area per unit volume of the mixture.

Title: Optical packet routing network system based on optical label switching technique
Inventor: NOGUCHI KAZUTO
IPC: H04L12/56
Filed: 2000-08-24
Abstract: An optical communication equipment comprises shared optical sources to be shared by communication nodes, the wavelengths of optical signals are converted into desired wavelengths according to the addressed information of the corresponding optical label signals by using the shared optical sources, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG). The load of each communication node can be reduced by incorporating the multi-wavelength optical sources , which can be shared among individual communication nodes, into the router.      Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal ha been transmitted through the router in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers. In this way, the setting of the transmission time lag by each communication node can be made easier, thereby largely reducing the work load.

Patent CA-2328306-A1 (CA)
Title: Bimetallic plate
Inventor: HEIJKOOP TEUNIS
IPC: B22D19/08
Filed: 1999-04-16
Abstract: Bimetallic plate is produced by providing a substrate (S) of a first metal and, with the preheated substrate (S) positioned in a mould cavity (34) with a major surface of the substrate (S) facing upwardly and to fill a portion of the depth of the cavity (34), a second metal is cast against that surface to form a cladding component and, with the substrate (S), to form the bimetallic plate. Prior to the cladding being cast, the major surface is rendered substantially oxide-free and is protected against oxidation. The cladding is cast by a melt, of a composition required for it, being poured at a superheated temperature whereby, with the preheating of the substrate (S), an overall heat energy balance is achieved between the substrate (S) and the cladding. The heat energy balance causes a diffusion bond to be achieved between the major surface of the substrate (S) and the cladding, and attainment of the energy balance is facilitated by causing the melt to enter the mould cavity (34) through a series of gates (44) which provide communication between at least one runner (40) and the mould cavity (34). The series of gates (44) is disposed laterally with respect to flow of the melt therethrough whereby the melt forms a laterally extending melt front. Attainment of the heat energy balance is further facilitated by causing the melt front to advance away from the gates 144), over the substrate (S) surface, at a rate which is substantially uniform across the lateral extent of the front.
