Patent CA-2109395-C (CA)
Title: Centralized service circuit deployment
Inventor: BALAKRISHNAN ANNAPURNA
IPC: H04Q3/00
Filed: 1993-10-27
Granted: 1997-11-11
Abstract: This invention relates to the minimizing of call set-up time for calls requiring the use of service circuits provided from a separate switching system, such as a service circuit node (SCN). Groups of semi-permanent circuits through a public switched telephone network (PSTN) are allocated to each of the switching systemsserved by the SCN. Thus, whenever a switching system has a call that requires the use of a service circuit housed in the SCN, the connection is already established. Traffic is controlled by limiting the size of the semi-permanent circuit groups, but these groups can be made larger or smaller, up to some overall total for the SCN, as traffic to each switching system changes. Advantageously, this arrangement permits efficient use of a large group of service circuits at the SCN, while minimizing the total call set-up time.

Title: Method for shaping cover materials
Inventor: THARY CHRISTIAN
IPC: B29C39/26
Filed: 1993-05-05
Granted: 1998-11-24
Abstract: A method for three-dimensionally shaping cover materials such as woven or knitte d fabrics, vinyl, leather, and the like is performed by providing a cover material (18) and a layer of foamable liquid reac tion mixture such as polyurethane which changes from liquid to a viscous state (16') at the beginning of the gas generat ing reaction, compressing the combined cover material and the foamed layer in a mold (21, 22) having surface configurations correspond ing to desired final three-dimensional shapes with the compression being performed when the foam layer has substantiall y completed rising, but before substantial curing thereof takes place, and then allowing the foamed layer bonded to the cover mate rial to proceed in curing reaction. The three-dimensional cover material shaping is performed by this method without ext ernal heat or high pressure so that the cover material can retain its original appearance and high quality. By changing locally the spa cings between mold halves (21, 22), the resultant foam layer bonded to the cover material can be provided with portions having dif ferent local thicknesses and hardnesses.

Abstract: A ground fault circuit interrupter (GFCI) line cord plug utilizes an electronically latched relay, rather than a circuit breaker or other type of mechanical latching device, to interrupt the AC load power when a ground fault condition occurs. In order to reduce the size of the relay and minimize the cost and complexity of the GFCI plug, the fixed and movable relay contact structures are mounted directly to the circuit board which carries the remaining components of the GFCI circuit. In a preferred embodiment, the fixed relay contact structures are integral with the plug blades of the GFCI plug. The movable relay contact structures preferably comprise deflectable spring arms which are preloaded when the relay contacts are in the open position in order to control the contact gap, and which are deflected past the point of contact closure when the relay contacts are in the closed position in order to increase the closing force. The principal electrical components of the GFCI plug, including the relay contacts, relay coil and sensing transformer, are mounted on the circuit board in a generally tandem or in-line arrangement in order to minimize the dimensions of the plug.
