Granted: 1999-03-09
Abstract: A control system emulates a multi-tasking environment using a single tasking processor. A number of predefined tasks are provided in a task library. When a host application needs processed data from a data source, the host application creates a pipeline of initialized instantiations of one or more of the tasks from the task library. When the host application invokes the pipeline, the data request is made from the host application to a downstream-most section of the pipeline. The data request ripples upstreamwardly to the upstream-most instantiation of one of the tasks from the task library. The upstream-most instantiation of a task obtains data from a data source and returns it downstreamwardly to the host application, each instantiation of a task from the task library further operating on the data.

Granted: 2005-11-01
Abstract: A heat exchanger comprises a clam shell having a first passage, a second passage and a third passage connected sequentially in a plane. A hot collector box made from metal, for example, aluminized steel, is connected to the third passage. A secondary heat exchanger coil is operatively connected to the hot collector box. A second collector box or cold collector box made from plastic is connected to the outlet of the secondary heat exchanger coil. Condensate from the flue and condensate from the cold collector box may be discharged in a common line from the furnace. The clam shell is constructed and arranged to remove about 90%-95% of the energy from the flue products flowing therethrough.   The heat exchanger is disposed in a passage between the inlet and the outlet in the housing of a furnace. Air is forced over the heat exchanger, which is disposed in the passage, by a blower in the housing.

Abstract: A conveying system in a production line for conveying a plurality of objects is disclosed. The conveying route comprises first rails and second railsr, extending in the different directions and intersect with each other. Each object has a driven portion including a moveable section pivotably supported on the objects. A first conveyor has a mechanism for advancing the rollers pressed against the driven portion toward an intersection when the object comes on the first rails near the intersection, and for retracting the rollers to cause them to remove from the driven portion when the object comes onto the intersection.     A second conveyor has a mechanism for retracting the rollers toward the intersection when the object comes onto the intersection, and for advancing the rollers toward the second conveyor when both rollers are pressed against the driven portion of the object on the intersection. The intersection has a mechanism for turning the movable section from the extending direction of the first rails to the extending direction of the second rails for changing the conveying direction of the object.

Abstract: A tunable waveguide grating includes a plurality of N waveguides which define N optically transmissive pathways. A plurality of (N-1) electrodes are arranged in the pathways such that the kth pathway contains (k-1) electrodes, where O < k < N. As a result of this arrangement, an optical signal propagating through the kth pathway will experience a phase shift provided by each of the (k-1) electrodes arranged in that pathway. Consequently, in contrast to prior tunable optical gratings, each electrode may contribute a phase shift to the portions of the signal propagating through several waveguides and hence as the number of waveguides increases no individual electrode is required to produce relatively large phase shifts.

Abstract: Electrical connector having a latch to hold it to a support in working position. Included is a pivoted handle which normally lies close to the connector body, but which is accessible to allow it to be moved to a position for gripping to allow for connector removal from the support. The handle is connected to the latch so that as the handle moves to the position for connector removal, it automatically disconnects the latch thereby permitting withdrawal of the connector. Useful for connector positioning in confined spaces and allows for narrower circuit pack designs while also including essential latch mechanisms which, because of the narrow designs, are manually inaccessible.

Abstract: L'invention se rapporte à un procédé de transmission de messages entre des programmes d'application, qui permet d'assurer qu'aucun de ces messages n'est perdu et n'est transmis plus d'une fois. Le procédé utilise la mise en file d'attente asynchrone des messages. Un ou plusieurs programmes (100) de gestion de files d'attente sont prévus dans chaque ordinateur d'un réseau afin de commander la transmission des messages vers et à partir de cet ordinateur. Les messages à transmettre vers un gestionnaire différent de file d'attente sont placés sur des files d'attente de transmission spéciales (120). Afin d'effectuer la transmission vers un gestionnaire de file d'attente adjacent, un processus de transmission (130) se trouvant sur le gestionnaire de files d'attente local (100) récupère des messages à partir d'une file d'attente de transmission et les envoie sous forme d'un lot de messages dans une unité commandée par un gestionnaire de points de synchronisation. Un processus de réception (50) se trouvant sur le gestionnaire de files d'attente de réception reçoit les messages et les place, dans une seconde unité commandée par un gestionnaire de points de synchronisation, dans des files d'attente (180) qui sont sous la commande du gestionnaire de files d'attente de réception. L'émetteur coordonne l'attribution du lot en transmettant une requête d'attribution et de confirmation d'attribution avec le dernier message du lot, l'attribution au niveau de l'émetteur étant déclenchée par la confirmation qui est envoyée par le récepteur en réponse à la requête. L'invention permet d'éviter la circulation supplémentaire de messages qui est une caractéristique de procédures d'attribution en deux phases, ainsi que la nécessité de synchronisation réciproque des gestionnaires de ressource. Elle permet d'autre part de réduire les circulations d'attribution en permettant le regroupement par lots d'un certain nombre de messages.

Abstract: A transmission is provided for converting rotary input into an oscillating output. The transmission includes a housing with an input shaft and an output shaft, and a series of gears interconnecting the shafts. The gears include a pair of rack gears on opposite sides of an output pinion mounted on the output shaft. The rack gears are held in meshing engagement with the output pinion by a carrier which is mounted upon a floating bushing on the output shaft. The floating bushing allows the rack gears and rack carrier to move side-to-side relative to the output shaft, thereby equalizing the load on the rack gears and preventing binding between the teeth of the rack gears and the teeth of the output pinion.

Abstract: A spread-spectrum CDMA interference canceler for reducing interference in a DS/CDMA receiver having N chip-code channels. The interference canceler includes a plurality of correlators (54, 64, 74), a plurality of spread-spectrum-processing circuits (55, 65, 75), subtracting circuits (150), and channel correlators (146). Using a plurality of chip-code signals generated from chip codeword signal generators (52, 62, 72), the correlators (54, 64, 74) despreads the spread-spectrum CDMA signal as a plurality of despread signals. The plurality of spread-spectrum-processing circuits (55, 65, 75) uses a timed version of the plurality of chip-code signals generated from the delay devices (53, 63, 73), for spread-spectrum processing the plurality of despread signals. For recovering a code channel using an ith chip-code-signal, the subtracting circuits (150) subtracts from the spread-spectrum CDMA signal, each of the N-1 spread-spectrum-processed-despread signals thereby generating a subtracted signal. The channel-correlator (146) despreads the subtracted signal.
