Patent CA-2158599-A1 (CA)
Inventor: DRAGONE CORRADO
IPC: H04B10/29
Filed: 1995-09-19
Abstract: A monolithically integrated laser which is rapidly tunable over a wide optical frequency range comprises a frequency router formed in a semiconductive wafer defining a tuned cavity.  A control circuit applies electrical energy to predetermined controllably transmissive waveguides connecting the frequency routing device with reflective elements defined in the wafer.  This tunes the laser to a desired one of a plurality of optical frequencies.          Application of such electrical energy creates frequency selective pathways through the wafer able to support selected lasing frequencies.  This laser is economical to construct and is useful in high capacity, high speed optical communications networks.

Title: Methods of preparing french racks and/or apparatus used therefor
Inventor: PETERSON CRAIG STUART
IPC: A22C17/00
Filed: 1994-03-30
Abstract: French racks are formed from a prepared section of rib carcass using water jets to cut a line through the meat, fat, collagen and membrane without cutting the bone using a plurality of parallel jets impacting the rib section at an angle to remove the meat, fat, collagen and tissue from the rib bones beyond the cut formed by the first water jets. The apparatus allows an operator to insert the rib section and relative movement between the rib section and the water jets transforms the rib section into the french rack. The water jet is operator controlled.

Title: Multiprocessor cluster membership manager framework
Inventor: ALFIERI ROBERT A
IPC: G06F11/00
Filed: 1996-06-19
Abstract: A shared-disk cluster system includes a cluster membership manager framework which coordinates the joining or leaving among all nodes in a cluster including taking the multiple layers of involved subsystems through transitions. Subsystems are notified of transitions in particular order depending upon the transition, and all nodes' subsystems receiving a notification must process that notification prior to another layer of subsystems being notified. One of the subsystems registered for notification is an event manager in user space. The event manager carries out transfers of client services, including user applications, resulting from nodes joining and leaving the cluster. This includes a registration and launch service which registers a node, or multiple nodes, in a cluster which claims, or is assigned, responsibility for the service and provides an optional launching function which initiates the client service upon successful registration.

Title: Method of Modification of Bulk Polymers with Metal Catalyzed Ionic Polymerization
Inventor: AGUIRRE JUAN E
IPC: C08F8/44
Filed: 1995-03-01
Abstract: A method for property modification of bulk polymers, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), natural rubber and the like, by initially treating a short chain organic acid, having a carboxylic group (with dissociation constant between 10-2 to 10-6 cm-1, and less than 8 carbons); with an oxide, peroxide, hydroxide or halogen compound of a Group IA, IIA or IIB metal, or the metal itself, and preferably a divalent alkaline earth metal, for forming a metal ligand or complete metal salt of the acid. The bulk polymers, are thoroughly mixed with the complex metal salts, such as in an extruder, and free radicals are introduced into the mixture, such as by means of addition of a highly oxidizing material, such as a peroxide, to functionalize the bulk polymer with ionic polymerization sites, with a resultant homopolymer formation between the organic metal salt anion and the bulk polymer, as catalyzed by the metal cation at such sites. The polymerization is a substantially non-cross linked ionic one resulting from the dissociation parameters and short chain length of the complex metal salt. The metal salt anion appears to fill in gaps in the bulk polymer but without cross-linking. Resultant homopolymer materials including those containing bulk polymers of PE, PP and PVC show improvement in flow rate, elongation and tensile strength over the original bulk polymer materials, and natural rubber behaves like a thermoplastic polymer.

Abstract: In a method of treating composite elements of solid organic and/or inorganic composite substances - such as metal/metal, plastics/plastics or metal/plastics composites or mineral composites containing metals and/or plastics - solid particles are produced from the composite elements and added to a conveying fluid. At least one flow obstacle, such as a separating edge, disposed transversely to the flow of the mixture of solid particles and conveying fluid, is moved relative to said flow in order to form eddies which accelerate and break up the mixture. The mixture is fed to the separating or breaking-up process at the separating edge(s) at an acceleration of 20 to 60 m/sec2, and the composite element preferably is desintegrated before the separating or breaking-up process.

Abstract: A controller (42) for detecting abnormal operating conditions of a continuous motion machine (12) such as a packaging machine. The acceleration and velocity of each motor (14) for the various axes (16) of the machine (12) are examined by the controller (42) and rapid deceleration or a more gradual deceleration to a lower velocity relative to a machine velocity are employed for stopping the machine (12) when overloads in the form of jams or mechanical faults occur in moving parts of the machine. By using this system, machine overloads can be detected much earlier than by using conventional techniques, and as a result, damage resulting from overloads and nuisance tripping can be eliminated or greatly reduced.
