Title: Splice synchronization system
Inventor: PIPKORN ALAN J
IPC: B65H39/16
Filed: 1994-09-12
Abstract: SPLICE SYNCHRONIZATION SYSTEM               Abstract of the Disclosure A system for coordinating the splices in each of the component webs used in making a composite corrugated paperboard web independently measures on a dynamic real time basis the length of each component web between the splicer where it is supplied and a downstream cutoff apparatus where the synchronized splices are cut out in a short length of web in which they are contained. The real time measurement of each component web includes continuous monitoring of web lengths subject to change while running through variable length storage areas, and an initialization procedure whereby an initially unknown length of component web in its respective storage is determined.  The system also includes a calibration procedure by which the various devices used to measure running web lengths throughout the system are all calibrated to a master device which controls the total web length for each order.  Accuracy of the system is further enhanced by independently monitoring the response time of each splicer to its activating control signal and adjusting, as necessary, the timing of the control signal for measured variations in response time.

Patent CA-2146469-A1 (CA)
Inventor: COMERFORD TIMOTHY N
IPC: H04M1/652
Filed: 1995-04-06
Abstract: An auxiliary baseband telephone instrument interface is provided in an answering machine to which any auxiliary telephone instrument, whether corded orcordless, can be connected and can control the answering machine functionality by use of in-band control signals. More specifically, a controllable switch arrangement is employed to connect outputs of an auxiliary instrument jack to outputs of a telephone line jack to which the answering machine is connected, or to the answering machine functionality itself and to disconnect the outputs of the auxiliary jack from the outputs of the telephone line jack or the answering machine functionality. Use of unidirectional paths controlled by a plurality of switching elements allows the user of an auxiliary telephone instrument connected to the auxiliary instrument jack to privately screen incoming calls on a telephone line connected to the telephone line jack, which the answering machine has answered and to controllably access other remote features of the answering machine. During the private screening of a call, a user of the auxiliary telephone instrument can interrupt the answering machine operations by entering an in-band control signal and thereby intercept the answered call. Additionally use of the controllable switch array enables a user of the auxiliary telephone instrument to answer incoming calls, if desired, or to make outgoing calls, if desired.
