Patent CA-2327778-A1 (CA)
Inventor: STAYT JOHN WILLIAM JR
IPC: H04B10/50
Filed: 2000-12-07
Abstract: A laser module, disposed within a wavelength stabilized control system, is provided with an integral modulator and optical amplifier. The laser module has a first output connected to an optical link and a second output connected to a controller via a signal discriminator circuit. The controller controls a channel selection process for the system. During the channel selection process, the controller adjusts a gain section, the modulator and amplifier as necessary to reduce the transmission power of the first and second outputs so that the first output can not be detected by a receiver connected to the link. The controller initiates the channel selection process by adjusting the laser module and monitoring etalon characteristics of the second output. By tracking the etalon characteristics, the controller can determine when a wavelength of a desired channel has been obtained. Once the wavelength has been obtained it is locked and stabilized. Subsequently, the controller adjusts the gain section, modulator and amplifier to obtain transmission power for the first and second outputs allowing the first output to be detected by a receiver connected to the link. This way, a channel selection process can be performed without turning off the laser module, or its outputs, and without corrupting any data on the optical link.

Abstract: A method and system are provided for optimizing the local caching of one or more data components available from a server node. Each of plural nodes connected to a local area network is provided with a locally physically present cache. Each of the caches of at least some of the plurality of nodes  are linked together into a single virtual cache. A particular one of the nod es is designated as a repository node for persistently storing a particular dat a component and for providing a copy of the particular data component to other  referencing nodes of the plurality of nodes which lack, but which desire to access, the particular data component. Designation of the particular node as  the repository node is unchanged solely by providing a copy of the particula r data component to one of the referencing nodes that desires to access the particular data component. The repository function of a node for a particula r data component is relatively static. For instance, assume that a first referencing node obtains from the repository node a copy of the particular data component and performs a group of one or more access operations on the copy of the data component. If another referencing node lacks a copy of, but  desires to access, the particular data component, a copy of the particular data component is provided from the repository node to the other referencing  node. One of the nodes may be designated as a monitor node for the particula r data component. The monitor node responds to requests by each referencing no de to identify the repository node of the particular data component by providin g the identify of the particular node which serves as the repository node for the particular data component.

Patent CA-2345130-A1 (CA)
Inventor: KLOTZ BERND
IPC: B29C45/14
Filed: 1999-09-21
Abstract: The invention relates to a method for producing a composite plastic moulded part consisting of at least one layer of a sheet material and a plastic body, using an injection moulding tool. According to this method, the sheet material is placed in the injection moulding tool and deformed as the tool is closed. Negative pressure is then applied to one side of the sheet material or excess pressure is applied to its other side, so that the sheet material comes to rest on a mould half. Plastic material is then introduced into the opening injection moulding tool in such a way that the incoming flow rate of the plastic material and the opening speed of the injection moulding tool are co-ordinated with each other. Once a certain opening gap has been reached, the mould is closed and the plastic moulded part is embossed. The inventive method enables greater embossment distances to be achieved in vertical and horizontal machines.

Abstract: L'invention concerne un procédé d'acheminement d'un courant de gaz riche en méthane, tel que du gaz naturel. Dans la première étape de ce procédé, on achemine le gaz vers un pipeline (47), à une pression d'entrée de pipeline (47) sensiblement supérieure à celle de sortie de celui-ci. La chute de pression dans le pipeline (47) provoque un abaissement de la température du gaz, de préférence en dessous d'environ 29 ·C (-20 ·F). On règle la pression d'entrée du gaz dans le pipeline (47) afin d'obtenir une pression de sortie déterminée du gaz, à la sortie du pipeline (47). Puis on liquéfie le gaz sortant du pipeline, afin d'obtenir un gaz liquéfié dont la température est supérieure à environ 112 ·C (-170·F) et dont la pression est suffisante pour que le liquide soit à sa température de point de bulle, ou inférieure à celle-ci. Ensuite, on transporte le gaz liquéfié dans un contenant (66) approprié.
