Patent CA-2300396-A1 (CA)
Title: Superfluorescent fiber source
Inventor: BEGIN MICHEL
IPC: H01S3/067
Filed: 2000-03-07
Abstract: A low-cost superfluorescent fiber souce. A gain medium in a length of optical fiber is pumped in counter-propagation by a pump source, producing superfluorescent radiation. The pump source is coupled to the fiber by a first coupler, disposed forward of the gain medium, that selectively transmits the pump signal in the backward direction, and the superfluorescence in the forward direction. A second coupler is disposed backward of the gain medium, selectively transmitting the backward propagating superfluorescent radiation along a first path and the pump signal along a second path, the pump signal is absorbed in the second path by a high-attenuation fiber, to avoid feedback to the pump laser, and the superfluorescent is reflected in the first path back toward the source output.   Advantageously, this source can be realized with readily available optical , components that are easy to assemble and do not require any alignment.

Inventor: REAMES GARY
IPC: B29C45/16
Filed: 2000-07-18
Abstract: An article of manufacture, such as an encapsulated dual lens sealed instrument cover, includes four components, namely, a first lens having a peripheral edge encapsulated by a polymeric/polymeric injection molded encapsulation or border and a second lens also have a peripheral edge encapsulated by a second injection molded polymeric/copolymeric encapsulation or border. A hermetic chamber is thereby formed between the two lenses. The first encapsulation is also provided with threads or similar fastening means to readily secure the instrument cover to an instrument "can" containing any variety of instruments, such as a nautical compass, amperage/voltage, fuel, etc. The first lens is inserted into a cavity of a mold and the first ecapsulation is injection molded thereabout. The latter two components are then assembled with respect to the second lens and the second encapsulation is injection molded thereabout. This double injection molding process to manufacture the dual lens sealed instrument cover creates "anti-fog" characteristics and allows more rapid and cost-effective manufacturing than heretofore provided by conventional techniques utilizing metal crimping and sealing techniques.

Title: Method to seal a planetary rotor engine
Inventor: MASTERSON FREDERICK
IPC: F01C1/067
Filed: 1999-05-27
Abstract: Methods of sealing a planetary rotor engine (10), and the resulting seals, are described which improve the engine's efficiency and solves each of three main problem areas. A first method and resulting dynamic seal for sealing the rotor face surfaces as they translate across one another to constantly reform the contact between each other includes the key step of moving the shaft centerlines of each of the rotors (16, 18, 20, 22), thereby radially positioning the rotors along diametric axes at positions which compensate for varying thermodynamic conditions (e.g. thermal expansion or contraction of rotor material). A second method and resulting dynamic seal for effectively minimizing leakage between the end space formed between the rotor end and the case includes the key step of introducing a surface depression (46) of any shape on one, or both of the rotor end (36, 38, 40, 42) and opposing casing (13, 14), thereby eliminating the need for a frictional seal and, in essence forming a pressure wave plug. A third method and resulting dynamic seal for sealing around the rotor centershaft takes advantage of and is responsive to the changes in pressure and partial vacuum pulses during the operation cycles of the engine. An annular pivot and lever seal (44) comprises a specially configured annulus for surrounding the centershaft having, generally described, a pivotal H-shaped cross section configuration adapted to seesaw in correspondence with positive and negative pressure changes over a single pressure wave to seal against the adjacent inner wall of the rotor case.

Abstract: A client at a remote site may order each of a series of images from a low resolution image database, and may then assemble these images and text into a marketing piece. Once assembly is complete, the client orders the system proprietor to produce the marketing piece according to the client's specifications. The client communicates to the system proprietor via a web site on the Internet, which has associated with it a pair of applications for the ordering of images and the assembly of marketing pieces. The client assembles the marketing piece according to one of a series of predefined templates, which constrains the choices which the client has such that the produced marketing piece will have the look and feel dictated by the client's company. The templates, each of which has associated with it a series of slots for the placement of image or text, also permit easy assembly of a marketing piece by simply specifying the material which goes within the slot. A catalog of low-resolution images are sent over the Internet to the client for his or her consideration, and a corresponding set of high-resolution images are used to produce the marketing pieces.
