Title: System and method for establishing dynamic high usage trunk groups
Inventor: LAKHANI FAIZEL
IPC: H04L12/56
Filed: 1998-10-08
Abstract: The present invention relates to a system and method for provisioning dynamic high usage trunk groups between end offices in a switched telephone network. The system includes a transit trunk subnetwork with ATM facilities connected between the end offices. A call manager communicates with the end offices and the ATM facilities to process signal messages from the end offices, which are sent to interfaces between the end offices and ATM facilities. The interfaces are configured to dynamically set up and release switched virtual circuits in response to signal messages from the call manager. In an alternate embodiment of the invention, an element manager in the end offices is configured to receive signal messages from the call manager to dynamically provision high usage trunks between the end offices.
Patent CA-2250387-A1 (CA)
Inventor: POWELL WILLIAM E
IPC: H04L12/56
Filed: 1998-11-04
Abstract: An existing synchronous residual time stamp (SRTS) algorithm (76, 78, 80, 82, 106, 104) is used in conjunction with adaptively filtered buffer fill information (74) to reconstruct an original constant bit rate (CBR) payload clock rate (102) for asynchronous transfer mode (ATM) CBR payloads (88, 96).  The SRTS time stamp (96) is used as the primary factor used to recover the payload clock rate, but a secondary payload frequency correction factor (112) is generated by filtering (118, 120) the desynchronizer buffer fill position.  This correction factor is determined as part of a feedback arrangement which adaptively (128) alters the filtering time constant based on the offset position of the buffer from its center.  In this way, payload clock frequency (102) is corrected, even in the presence of loss of synchronization PRS traceability between mapping and desynchronizer nodes to keep the desynchronizer buffer from overflowing.

Title: Oil/water separator
Inventor: STOWELL JAMES RICHARD GEORGE
IPC: B01D17/028
Filed: 1998-10-30
Abstract: An Oil/Water Separator apparatus includes a portable container advantageously having rigid sides, including spaced apart side walls and rigid floor. Within the rigid container are defined at least two, advantageously, three chambers in an adjacent array in a downstream direction. The chambers are separated by rigid separating partitions or baffles rigidly mounted to, so as to extend between, the opposite side walls of the container.  Adjacent chambers are connected in fluid communication therebetween so that influent water containing oil to be separated may enter into a first upstream reservoir chamber. The influent water is deposited into the reservoir chamber. A downstream partition or baffle separates the reservoir chamber from the downstream coalescing chamber. The first partition has an opening under a lowermost edge thereof. Water passes under the partition from the reservoir chamber into the coalescing chamber. In the coalescing chamber, mounted in the water flow path, is a coalescing pack releasably rigidly mounted between the partition and a weir partition rigidly mounted to the floor. Emulsified oil within the water flow coalesces within the coalescing pack and is separated as oil droplets flow upwardly to the water surface within the coalescing chamber. The water flow leaving the coalescing pack is directed downwardly so as to pass into conduit passing over or through a downstream weir partition so as to flow into an outlet chamber.

Patent CA-2267392-A1 (CA)
Title: Binder with outwardly biased gusset
Inventor: MOOR MARC
IPC: A45C3/02
Filed: 1999-03-26
Abstract: The invention provides a binder or portfolio for carrying looseleaf paper, books, school supplies, etc. wherein said binder includes a flexible gusset attached to the front and back covers of the binder. The covers of the binder are foldably attached to a central spine and the gusset is split into two sections running along the periphery of the inner sides of the covers. The gusset is provided with a means for releasable attachment such that when the front cover of the binder is folded over the back cover of the binder, the two sections of the gusset may be attached to one another, thereby securing the contents of the binder inside.  Preferably, the releasable means of attachment is a zipper-type closure. The gusset is attached to the covers of the binder in such that the gusset is biased outwardly of the binder. This construction of the gusset has many advantages over prior inwardly biased gussets including generally unfettered access to the contents of the binder when it is laid open flat, the ability to make a binder having a smaller footprint than prior binders for the same size paper since the gusset occupies minimal space in the closed binder, and increased ease of detachment and reattachment since the contents of the binder do not interfere with this procedure.

Title: Measurement procedure for aurally correct quality assessment of audio signals
Inventor: THIEDE THILO
IPC: G10L25/69
Filed: 1999-05-12
Abstract: The measurement procedure assesses the interference of an audio signal or test signal, respectively, (1a,b) by comparing it with a reference signal (1c,d) that is not subject to interferences.      After pre-filtering (2) with the transmission functions of the outer and middle ear, the input signals are converted into a time-tonality representation. The squares of sums (5) of the filter output signals are calculated (rectification) and folding of the filter outputs is carried out with a smearing function (4). The folding can be done either before or after rectification. Level differences between test signals and reference signals, as well as linear distortions of the reference signals are compensated at (7) and evaluated separately. Then, at (8), a frequency-dependent offset is added in order to model the inherent noise of the auditory process., and the output signals are time smeared at (9). In order to save computer time, some of this time smearing can take place immediately after rectification (4). After time smearing (8) (low-pass filtering) it is then permissible to underscan the signals. A series of output values can be calculated at (10) by comparison of the resulting aurally corrected time-frequency patterns of test and reference signals (1a,b and 1c,d); these output values provide a assessment of the perceivable interference.
