Patent CA-2219055-A1 (CA)
Title: A dialing plan for special access applications such as telemetry systems
Inventor: SMITH DAVID B
IPC: H04Q3/42
Filed: 1997-10-23
Abstract: A utility meter or other fixed device is assigned a permanent dialed number that is unrelated to the telephone number of the customer premise where the device is located. Instead, the dialed number is permanently assigned to a line termination location in the switch such that when the dialed number is dialed a connection is made to the line terminated at that physical location in the network switching system irrespective of the customer's telephone number. As a result, the number dialed by the calling party is unrelated to the customer's telephone number such that changes in a customer's telephone number do not affect the telemetry system. Moreover, the telemetry number could be selected from a specified range of numbers or could include a predetermined command digit such as *8 prior to the number string. As a result, the switching system is able to identify that the request is for a special service such as telemetry connection by the dialed telemetry number rather than by the trunk on which the call is received. Thus, the availability of the service will not depend on access to specialized trunks.

Patent CA-2221317-A1 (CA)
Inventor: NEILSEN LARRY E
IPC: H04N5/44
Filed: 1996-06-03
Abstract: Un récepteur reçoit un signal ATV (par exemple, HDTV) dans une zone soumise à un brouillage dans la même voie NTSC et à d'autres interférences. Le signal reçu est codé préalablement au niveau de l'émetteur afin de pouvoir limiter le brouillage dans la même voie NTSC dans le signal reçu. Le signal reçu comprend des signaux de synchronisation de trame soumis successivement à un filtre à peigne, de manière à produire un signal de soustraction. Ce signal de soustraction est soumis à un filtre à peigne afin de limiter le brouillage dans la même voie NTSC et appliqué à un comparateur (36) avec le signal de soustraction non filtré. Le comparateur détermine si le niveau de brouillage dans la même voie NTSC est suffisamment important pour soumettre le signal ATV reçu à un filtre à peigne, afin de limiter ledit brouillage.

Title: Adaptive channel allocation in a frequency division multiplexed system
Inventor: FRODIGH CARL MAGNUS
IPC: H04W16/10
Filed: 1996-06-20
Abstract: A method and system of adaptive channel allocation in a frequency division multiplexed system is provided. In the method and system, a subset of M  subcarriers is chosen from a larger set of N subcarriers available for communications on a link. As communications take place on the link, signal quality (C/I) measurements (342) on the subcarriers of the subset of M  subcarriers and interference (I) measurements (344) on the subcarriers of the group of N subcarriers are periodically performed. The C/I and I measurements are then used to reconfigure (422) the subset of M subcarriers to reduce co-channel interference on the link.

Title: Rigid cooling tower
Inventor: MAILEN GREGORY S
IPC: E04H5/12
Filed: 1998-02-02
Abstract: A cooling tower is disclosed that is resistant to lateral displacement while minimizing the number and type of parts, and while limiting the amount of horizontal bracing. The cooling tower has a fiber reinforced material skeletal frame. Moment-transferring connections are provided in the connections between the elements of the skeletal frame. The moment-transferring connections between the frame members are made by bonding the joined elements to a mounting plate. The mounting plate may be held in place by mechanical fasteners that bear construction loads until the bonding material cures. The mounting plate, columns, beam and mechanical fasteners define construction joints that are capable of bearing construction loads until the bonding material cures. The mounting plate, columns, beam and cured bonding material define post-construction joints that are capable of transferring moments from the beam to the columns and are capable of bearing post-construction loads on the joints. The post-construction joints may also include the mechanical fasteners. Deflections of beams with the post-construction joints are more like a model beam with moment-transferring joints than a model beam that is simply supported.

Patent CA-2234184-A1 (CA)
Inventor: ROSS BRUCE
IPC: B65D90/34
Filed: 1998-04-07
Abstract: A method and apparatus to control gas breakout in transport tanks. The method involves the step of coupling in series hook up to a transport tank, a pressure relief valve and a gas scrubber. The pressure relief valve limits the quantity of gas being released from the transport tank and the gas scrubber scrubs all gas that is released. By limiting the gas being scrubbed to only such gas as is released by virtue of the operation of the pressure relief valve, the volume of gas being scrubbed and, consequently, the costs associated with scrubbing the gas are drastically reduced.
