Patent CA-2256870-A1 (CA)
Title: Environmentally compatible solid film lubricant
Inventor: NOVAK HOWARD L
IPC: C10M107/32
Filed: 1998-12-18
Abstract: A solid film lubricant useful for aerospace and other heavy machinery applications comprising a mixture of boric acid and molybdenum disulfide in a polymeric binder comprising a silicone polymer and an epoxy resin is provided. Boric acid and compounds related to boric acid can be effectively used as inorganic lubricant components in solid film lubricants in place of graphite thereby avoiding galvanic corrosion induced by graphite. The boric acid containing solid film lubricant provides superior lubrication at the high stress levels common for booster rockets and other aerospace applications, but without inducing galvanic corrosion, or exposing workers and the environment to toxic materials such as lead compounds. In addition, it affords substantial savings in labor, due to the need for only one coat, and savings in energy due to the substantially lower cure temperature of about 450°F compared to 1000°F for a currently used two coat ceramic system. There is also a significant savings in time, hazardous waste disposal costs and human protection costs by using the boric acid containing SFL.

Patent CA-2257960-A1 (CA)
Title: Flexible bandwidth negotiation for the block transfer of data
Inventor: BERGER ARTHUR W
IPC: H04L12/56
Filed: 1997-06-10
Abstract: When a network element receives a request for an increase in bandwidth via a resource management (RM) cell, the network element determines the rate that it can support. If the rate that the network element can support is less than the requested rate, rather than simply rejecting the requested rate, the network element overwrites the rate encoded in the appropriate field in the arriving RM cell with a lower rate than requested. If the network element can support the requested rate, the rate encoded in the RM cell is left unchanged and the RM cell is transmitted to the network along the connection.

Title: Device and method for compensating phase distortion
Inventor: HELLMARK MARTIN
IPC: H03F1/34
Filed: 1997-06-10
Abstract: The present invention relates to a method of compensating for the phase distortion that occurs in a power amplified output signal in response to the output power of a power amplifier. The invention also relates to a phase distortion compensating device. The device includes a phase-locking and upconversion loop (30-39) which is connected to the input of a power amplifier (40). Briefly, the solution involves feeding a part of the signal (e pha) to be amplified back to a circuit (35) which combines this first mentioned signal with a part of the amplified signal (e out) fed back from the output of the power amplifier (40), so as to achieve a smooth transition in the dominance of one signal over the other signal when the two signals are combined to obtain a new feedback signal (e fdb) from the combining circuit (35).

Title: Sealing device for gas turbine stator blades
Inventor: TOMITA YASUOKI
IPC: F01D11/04
Filed: 1998-06-10
Abstract: A sealing device for a gas turbine stator blade, in which a sealing pressure of an inner shroud is raised to enhance a sealing effect. An outer shroud 32 is mounted through heat insulating rings 32a and 32b on a blade ring 50, and this blade ring 50 has air holes 1 and 51, of which the air hole 1 communicates with a space 53 whereas the air hole 51 communicates with a seal tube 2. This seal tube 2 is inserted at its leading end portion 3 into the air hole 51, and a spring 6 is arranged between a projection 4 of the tube 2 and a retaining portion 5 of the air hole 51 to fix the seal tube 2 removably. Cooling air 54 flows on one side from the air hole 1 into the space 53 to cool the shrouds and the inside of a stator blade 31 until it is released from the trailing edge, and on the other hand into a cavity 36 so that the inside of the cavity 36 is kept at a high pressure without receiving a pressure loss because the tube 2 is independent of the space 53.      The high pressure air from the cavity 36 flows out from seal portions 40a and 40b, as indicated by arrows S1 and S2, to prevent the inflow of the hot gas from a combustion gas passage.

Title: Buffering system employing per traffic flow accounting congestion control
Inventor: BONNEAU MARIE-CLAUDE
IPC: H04L12/56
Filed: 1999-05-27
Abstract: The method of buffering packets in a digital communications device includes defining an n-level hierarchy of memory partitions, wherein each non-top level partition has one or more child partitions at an immediately lower level of the hierarchy.  The memory partitions at the top-most level are pre-configured with a target memory occupancy size, and the target occupancy for each memory partition situated at a lower level is recursively computed in a dynamic manner based on the aggregate congestion of its parent partition, until the target occupancies for the bottom-most memory partitions are determined.  Each traffic flow which uses the buffer is associated with one of the memory partitions at the bottom-most level of the hierarchy and packet discard is enabled in the event the actual memory occupancy of a traffic flow exceeds its target occupancy. The memory partitions at higher levels are preferably associated with a group or pool of traffic flows, such as traffic flows associated with a particular egress port and class of service, to thereby selectively control aggregate congestion. The method allows full buffer sharing, the weighted distribution of memory space within a memory partition, and scales easily to large systems.

Patent CA-2276378-A1 (CA)
Inventor: OAMI RYOMA
IPC: H04N7/24
Filed: 1999-06-23
Abstract: A watermarking procedure that is applicable to images, audio, video and multimedia data to be watermarked divides the data to be watermarked into a set of nxn blocks, such as the 8x8 blocks of MPEG. The same watermark signal can be distributed throughout the set of blocks in a large variety of ways. This allows the insertion algorithm to be changed without affecting the decoders. The decoding procedure first sums together the DCT coefficients of N sets of 8x8 blocks to form a set of N summed 8x8 blocks and then extracts the watermark from the summed block. Since the sum of the DCT blocks is equal to the DCT of the sum of the intensity blocks, efficient decoding can occur in both the spatial and frequency domains. The symmetric nature of the decoding process allows geometric distortions to be handled in the spatial domain and other signal distortions to be handled in the frequency domain. Moreover, insertion of a watermark signal into image data and the subsequent extraction of the watermark from watermarked image data which has been subject to distortion between the times of insertion and extraction involves the insertion of multiple watermarks designed to survive predefined distortions of the image data, such as panscan or letterbox mode transformations. Alternatively, a registration pattern in the image data, after the image data containing the registration pattern is subject to an unknown distortion, is used to compensate for distortion of the watermarked image data.
