Patent CA-1278848-C (CA)
Title: N-by-n "knockout" switch for a high-performance packet switching system
Inventor: ACAMPORA ANTHONY
IPC: H04L12/56
Filed: 1987-08-05
Granted: 1991-01-08
Abstract: Abstract:    The present invention relates to an N-input, N-output "Knockout" packet switch which uses decentralized control and distributed routing.  More particularly, within the switch, the N input signals comprising fixed-length packets propagate along separate broadcast buses to each of N bus interface units which include N packet filters, a concentrator and a shared buffer.  Each bus interface unit is associated with a separate one of the N outputs of the switch, and the N packet filters therein are each associated with a separate one of the N broadcast buses for detecting if a packet on the associated bus is destined for the associated switch output.  The concentrator is used to reduce the number of separate buffers needed to receive packets which may arrive simultaneously and are destined for the associated output.  Contending packets at the output of the concentrator are stored in the shared buffer before placement on the output line on a first-in, first-out basis.  The lost packet rate of the "Knockout" switch can be made as small as desired and latency of packets in the switch is the smallest achievable by any comparable switch.

Title: Process and compositions for reinforcing structural members
Inventor: WYCECH JOSEPH S
IPC: B62D21/15
Filed: 1989-03-07
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE   A two-part system for reinforcing a hollow structural member and its method of use are provided. Part A of the two-part system is formed by adding a filler and unexpanded, thermally-expandable microspheres to a liquid thermosetting resin, such as an epoxy resin, in a quantity sufficient to produce a dough-like mass which can be readily kneaded. Part B is formed by adding a filler and a colorant, such as carbon black, to a liquid curing agent, again forming a dough-like mass. The curing agent is compatible with the thermosetting resin to promote cross-linking of the thermosetting resin upon contact with the curing agent.   A hollow structural member is cleared of debris or the like and may be preheated to enhance the rate at which the thermosetting resin cross-links. The two parts are blended together until a reactive third dough of substantially uniform mixture is formed. The uniformity of the blending is confirmed when the reactive third dough attains a uniform color intermediate the color between the colors of part A and part B. The blended reactive dough is then packed into the cavity of the cleaned structural member. The cavity is then preferably closed with a closure plate. As the curing agent promotes the cross-linking reaction of the thermosetting resin, the exothermic reaction generates heat which is transferred to the unexpanded, thermally-expandable microspheres, causing the microspheres to expand. The expansion of the microspheres causes the reactive dough to rise, substantially filling the cavity. As the reactive dough cures, it bonds rigidly to the surfaces which it contacts. The reactive dough is allowed to fully cure, whereupon a solid lightweight reinforcement member rigidly bonded to the structural member is formed. The reinforced structure has good strength and energy absorption characteristics. The present system is particularly suitable for use in reinforcing motor vehicle structures which have been cold-worked during repair of collision damage.

Title: Coin analyzer system and apparatus
Inventor: PARKER DONALD O
IPC: G07D11/00
Filed: 1989-07-06
Granted: 1993-11-09
Abstract: ABSTRACT         A coin analyzer system and apparatus that provides a detection circuit for comparing a tested coin with at least two different sample coins.  Two different sample coins are located in a magnetic field, and the tested coins pass through another region of the magnetic field.  In the event the tested coin does not match either sample coin, a rejecting gate forces the tested coin out of the coin chute in a laterally normal direction and into a rejected coin chute.  In the event that the tested coin matches either sample coin, the rejecting gate is opened and the tested coin drops through a substantially vertical accepted coin chute.  Credit is not extended the tested coin until the coin passes a confirmation sensor, and the determining circuit may be adjusted to vary the credit value extended to at least one of the sample coins.  A lockout circuit rejects and prevents a subsequent coin from being analyzed during the time that the circuit is crediting a prior tested coin with multiple credits.
