Patent CA-2202738-A1 (CA)
Title: Apparatus for detecting and responding to series arcs in ac electrical systems
Inventor: ENGEL JOSEPH CHARLES
IPC: H02H3/44
Filed: 1997-04-15
Abstract: Series arcs in an ac circuit are discriminated from other phenomenon by analyzing the timing between pulses in a second derivative of the current signal. A first timer starts timing upon detection of a first pulse in the second derivative of current signal. Time out of the first timer starts a second timer which times a second interval or window during which a series arcing fault will generate a second pulse of opposite polarity to the first pulse. Detection of the first pulse followed by a second pulse of opposite polarity during the window sets a flip-flop to record the event. When a predetermined number of events are counted by a counter within a given time-period set by a third timer, an output signal indicating an arcing fault is generated. If the second pulse is generated before the window opens, or a third pulse occurs during the window, the flip-flop cannot be set so that other events such as the switching of a dimmer do not generate a false output signal.

Patent CA-2207383-A1 (CA)
Title: Single substrate, repeat-pass printing process and substrates printed thereby
Inventor: CONRAD DANIEL JAMES
IPC: B41F17/00
Filed: 1995-11-20
Abstract: A low basis weight, continuously moving substrate (28) is printed by a single substrate, repeat-pass printing process. The continuously moving substrate (28) is passed a first time through the printing station (40) without receiving any pattern directly printed thereon, and is then repeat-passed through the printing station (40) and over a single-passing portion (46) of the substrate. The repeat-pass portion (78) then has an ink pattern directly printed thereon. Ink striking through the directly printed repeat-pass portion (78) of the substrate is collected or absorbed by the underlying single-pass portion (46) of the substrate, thereby preventing ink buildup on the printing apparatus.

Title: Traff-ad
Inventor: HARARI MOSHE
IPC: G09F15/00
Filed: 1997-11-28
Abstract: The "Traff-Ad" is illuminated street signage with logo oriented advertising. Thetastefully done illuminated logos will set the standard for locating the illuminated street signs from a much greater distance, thus reducing accidents through last minute lane changes. The logos will have no advertising text, unless the logo incorporates the name, to distract drivers. The illuminated street signs will have the street names in bold with to and from street numbers and the city or town they are installed in. These signs will be revenue generating for the municipalities helping offset future tax hikes. They are lighted with four fifteen-watt high output florescent bulbs for a total of 60 watts per sign. They are constructed in such a way to be able to withstand hurricane force winds and are virtually vandalism proof. They come with a photocell that will turn them on as night approaches, thus saving on the electricity consumption and at the same time in our winters when the snow builds up on the face of the panels during the day it will activate the photocell to turn the lights on. The heat that is generated from the lights being activated will melt the buildup of snow from the faces and once this is accomplished, will deactivate the photocell to shut off the lights.

Title: Methods for processing an outgoing and an incoming call in a mobile communications system
Inventor: PALVIAINEN KEIJO
IPC: H04M3/42
Filed: 1996-08-20
Abstract: The invention relates to a visitor location register and a method for handling an outgoing and an incoming call in a mobile communications system employing a multinumbering scheme.  Signalling originating from a mobile services switching centre (MSC) contains in case of a mobile-originating call the directory number of the calling subscriber and in call forwarding, the redirecting number. This directory number is obtained from the visitor location register (VLR). In accordance with the invention, all the directory numbers for different basic services of the mobile subscriber are transferred from the home location register (HLR) to the VLR. The VLR is thus capable of providing the MSC with the correct one of multiple directory numbers according to the basic service related to the call.

Title: Process and device to reshape binary signals
Inventor: CHAUZAT CORINNE
IPC: H04B10/00
Filed: 1998-04-06
Abstract: The procedure provides for synchronisation and signal shaping of a binary signal having a time bit, T0. The procedure includes forming p sampled signals (S.lambda-a, S-lambda-d) obtained from modulations of the signal (S) by pulses of frequency 1/T0, and of duration equal to T0/p. These are carried by p optical carriers of different wavelengths (lambda-a, lambda-d). The signals are delayed by application to delay circuits, such that the consecutive delayed signals are shifted in time by an interval (T0/p). The delayed signals produced in this way are then combined together to produce a new output signal. It is also possible to combine the sampled signals before their application to the delay circuits, taking advantage of their differences in wavelength.

Patent CA-2236710-A1 (CA)
Title: Flow line coupling
Inventor: CLAYSON ANDREW
IPC: F16L19/065
Filed: 1997-09-03
Abstract: A coupling assembly (10) for leak proof connection of the ends of two lengths of pipe or tubing. One end of a first pipe (12) is coupled to a coupling box (18) which is connected to or integrally formed on the end of a second pipe (14). The coupling box (18) has threads for engaging a nut (24) for securing the coupling. The coupling box (18) has a bore for receiving the end of the first pipe (12). The end of the first pipe (12) has an outer tapered surface for engaging an inner tapered surface of the coupling box (18) to form a metal to metal seal between the first pipe (12) and the coupling box (18). The bore also contains an engager (20, 22) for coupling the nut to the first pipe. The engager includes a split ring (20) which has a longitudinal slot. The split ring has internal circumferential projections or gripping teeth (80) which are aligned with external circumferential projections or gripping teeth (38) on the end of the first pipe (12). As the nut (24) is tightened, the split ring (20) is compressed so that the gripping teeth (80) of the split ring are brought into engagement with the gripping teeth (38) of the first pipe. The split ring (20) and the first pipe (12) are then moved relative to the coupling box (18) so that the outer tapered surface (40, 41) at the end of the pipe is forced into metal to metal sealing contact with the inner tapered surface (50, 52) within the bore of the coupling box (18).
