Patent CA-2052132-A1 (CA)
Title: Rule driven transaction management system and method
Inventor: KLEIN JOHANNES
IPC: G06F9/46
Filed: 1991-09-24
Abstract: ABSTRACT   During the processing of a transaction or other distributed computation, a computation management system creates a number of agents to handle various aspects or portions of the computations to be performed. Each agent progresses through a predefined set of state transitions which define the statusof the agent at any point in time. The computation management system defines for each agent a set of dependencies, each dependency corresponding to a state transition which will be blocked until a particular state transition occurs in another specified agent. By defining selected combinations of dependencies for each agent, a variety of different interdependencies and cooperating protocols can be implemented. The distributed processing management system can be used both for managing transaction processing and for synchronizing events in other types of distributed computations.

Title: Gas damped crash sensor
Inventor: THUEN TORBJORN
IPC: H01H35/14
Filed: 1991-12-23
Abstract: ABSTRACT OF THE DISCLOSURE Conventional ball-in-tube, gas-damped, crash sensors utilize a gold plated ball to bridge two contacts.  When the ball senses acceleration (deceleration) in the longitudinal direction of a cylinder of sufficient magnitude and duration, it moves to where it bridges the contacts, completing the electrical circuit and initiating deployment of a safety restraint system.  A switch activated by magnetic flux is combined with this type of gas-damped sensor to provide a solid and reliable contact duration and ensure the correct functioning of the sensor.  The level of biasing force for crash zone crash sensors of this type has been increased to avoid late firing problems on marginal crashes.

Abstract: In order to fabricate monomode active strip optical waveguides  for  optical  telecommunications,  a  layer  of vitreous  soot  is  deposited  on  a  substrate  and  is impregnated with a solution of a precursor of a rare-earth dopant, and radiation with a wavelength in an absorption band of the dopant is focused on the soot, and moved along a trajectory corresponding to the configuration desired for the guide, thereby forming a vitrified strip.  The soot may be pre-doped with a refractive index raising dopant, or a precursor of such a dopant may be included in the solution. The substrate may be of a polygonal tubular cross-section, and the soot deposited on an inside surface.  This enables several waveguides to be formed at once, and protects the soot layer from contamination.

Title: Polyvinyl pyrrolidone-grafted coatings on preformed polymers
Inventor: BERTRAND WILLIAM J
IPC: C08J7/16
Filed: 1991-12-04
Abstract: In an improved method for producing a surface graft of a hydrophilic polymer upon a preformed solid or semi-solid polymer substrate having hydroperoxide groups along its surface, n-vinyl pyrrolidone is utilized as the surface-grafting monomer, the substrate is selected to be insoluble in n-vinyl pyrrolidone, and the polymerization is carried out in aqueous alkaline conditions utilizing a combination of metal salts to provide a variable valence metal ion in a reduced state capable of oxidizing to suppress homopolymerization of the monomer in the solution. When the substrate is at least partially soluble in the n-vinyl pyrrolidone, an ethylenically unsaturated monomer having a higher reactivity with the substrate than n-vinyl pyrrolidone is added to the alkaline polymerization solution as a ''seeding'' monomer. Addition of the ''seeding'' monomer results in a surface-grafted copolymer effectively externalized from the substrate.
