Patent CA-2282308-A1 (CA)
Inventor: DEJACO ANDREW P
IPC: H04L69/40
Filed: 1998-03-02
Abstract: A test signal is aligned to a frame interval of a communication system. An alignment test signal having an alternating pattern of frequencies (220, 222, 224) is generated and transmitted over a communication link (108) that carries the alignment test signal in a sequence of frames (A, B, C). The alignment test signal is received over the communication link (108) as a return alignment test signal and then evaluated for frequency content. The start time of the alignment test signal is adjusted until the frequency content of the return alignment test signal corresponds to the alternating pattern of frequencies.

Title: Gas diffusion electrode with reduced diffusing capacity for water and polymer electrolyte membrane fuel cells
Inventor: KOSCHANY ARTHUR
IPC: H01M8/04291
Filed: 1998-03-06
Abstract: Gas diffusion electrodes (1) for polymer electrolyte membrane fuel cells are modified such that the diffusion of water therein is inhibited in comparison with unmodified electrodes. Polymer electrolyte membrane fuel cells with the modified gas diffusion electrodes can be operated, with on the average unchanged operating conditions, without addition of water, since the gas diffusion electrodes do not allow more water to escape than that formed during the reaction of burnable gas and oxidizing agent, and guarantee sufficient membrane moisture.

Patent CA-2283017-A1 (CA)
Inventor: CZUPPON THOMAS A
IPC: C01C1/04
Filed: 1999-09-22
Abstract: A vertical tubular reactor for converting ammonia synthesis loop purge gas to ammonia; a method for converting ammonia synthesis loop purge gas to form additional ammonia; and a method for retrofitting a conventional ammonia plant having a synthesis loop using an iron-based synthesis catalyst and having a purge gas stream, the method including a supplemental ammonia converter for the purge gas stream.      The supplemental ammonia converter is a shell and tube reactor. The tubes are filled with a catalyst comprising a platinum group metal such as ruthenium. The tubes are maintained in a substantially isothermal condition by boiling water in the shell side. As a retrofit modification to an existing ammonia synthesis plant, the purge stream is passed through the supplemental ammonia converter on a once-through basis to form additional ammonia and reduce the amount of purge gas.      Advantages of the retrofit modification include lower energy consumption, lower purge rates and higher ammonia production rates.

Title: Structural element made of a bent surface and a tensile membrane
Inventor: PADLEWSKI MARCIN W
IPC: E04C2/32
Filed: 2000-03-07
Abstract: A structural system that may be applied as an element in the construction of buildings, portable shelters, furniture, home accessories or where rigid structural elements are necessary. The invention of this system is based on two principal parts, which, when combined produce a system with a load bearing capacity. A flat surface or sheet is pre-deformed or tensioned by a limiting membrane, forming a curvilinear volume. The structure is comprised of a bendable surface or a sheet and a tensile membrane connected along virtually the entire periphery of the sheet. The membrane can envelop the entire sheet so that the sheet is bent inside it. Because of the sheet, the stretched tensile membrane assumes a saddle-shape, or a surface of negative Gaussian curvature.

Abstract: An open-architecture system and method of posting and paying invoices via the Internet permits multiple billers and multiple customers to use the system without requiring that customers be subscribers. A billing/payments facilitator establishes and maintains an interactive website that interacts with a database including selected particulars of individual billers and individual customers. For each invoice, the facilitator receives suitable billing data from a biller and posts the billing data on the website for access by the customer identified in the invoice. The facilitator notifies the customer that an invoice has been posted and provides the customer with a bill identification code. The facilitator displays the posted invoice to the customer upon receipt of such customer's bill identification code. The customer while on-line may authorize payment of the invoice by any approved electronic payment method.      The facilitator may deduct a transaction fee from the amount, the balance of which is passed on to the biller.

Title: Method and apparatus for dynamically allocating bandwidth utilization in a packet telephony system
Inventor: BAUER ERIC JONATHAN
IPC: H04L12/56
Filed: 2000-06-01
Abstract: A network monitoring agent is disclosed that monitors network conditions, such as traffic volume, and determines when to dynamically adjust the encoding scheme for one or more connections. The network monitoring agent can select an encoding standard based on, for example, current network traffic volume, network error characteristics, time of day or day of week. In the illustrative network traffic implementation, an encoding standard that provides a lower degree of compression and a higher quality level is selected at times of lighter network tragic. Likewise, as network traffic increases, an encoding standard that provides a higher degree of compression, although at a lower quality level, is selected in order to maximize the network utilization. The network monitoring agent notifies one or both of the devices associated with each connection of changes in the encoding scheme. Generally, both devices must change the compression algorithm at the same time, to ensure proper decoding of received packets. The initiating device inserts a notification in a field of a predefined number of packet headers to inform the recipient device that subsequent packets will be encoded with a different specified encoding algorithm, until further notice. Thereafter, the recipient device can load the appropriate codec to properly decompress and decode the received packets.
