Patent CA-2382671-A1 (CA)
Inventor: FREED PAUL S
IPC: A61M60/139
Filed: 2000-08-22
Abstract: An apparatus adapted to be inflated and deflated in response to selective communication with a source of pressurized fluid includes a bladder having a semi-rigid shell body portion (14) and a relatively thin membrane (24) portion defining an inflatable chamber (26). The elongate semi-rigid shell body preferably includes a contoured, concave inner surface (16) terminating at a peripheral side edge (18). At least one passage (20) extends through the shell body defining an opening in the inner surface of the shell body. The flexible membrane is continuously bonded to the shell body adjacent the peripheral side edge to define the enclosed inflatable chamber in communication with the passage. The membrane has a reduced waist portion (28) defining a membrane tension zone adjacent the opening of the passage into the chamber to reduce the probability of occluding the entrance while deflating the chamber.

Abstract: L'invention concerne un procédé permettant d'améliorer l'action herbicide de l'herbicide glyphosate, qui comporte l'adjonction d'un mélange d'un premier surfactant et d'un second surfactant à l'herbicide glyphosate, à un rapport en poids de surfactant total au glyphosate d'environ 1/30 à 2/1. Selon ce procédé le premier surfactant possède une structure chimique composée d'un groupe cationique ou d'un groupe amino-protonable et d'un groupe hydrocarbyle saturé ou insaturé, linéaire ou ramifié C8-24 et d'un second surfactant dont la formule est R-CO-NR'-(CR'2)n-COOM dans laquelle R représente un groupe hydrocarbyle, saturé ou insaturé, linéaire ou ramifié C7-23, n est compris entre 1 et 4, M représente un contre-ion hydrogène ou cationique, et les groupes R' sont indépendamment les uns des autres, hydrogène, C1-4 alkyle ou un groupe -(CH2)m-COOM dans lequel m est compris entre 1 et 4 et M est tel qu'il est défini immédiatement ci-dessus, à condition que pas plus d'un groupe R' ne soit pareil à un groupe -(CH2)m-COOM; le rapport de poids du premier surfactant au second étant environ de 1/10 à 10/1. L'invention concerne également une composition herbicide préparée conformément au procédé décrit ci-dessus. Le premier et le second présentent une interaction synergiste, qui augmente l'action herbicide de l'herbicide glyphosate.

Title: Improved vehicle seat hinge mechanism with reclining with forward dumping, memory return and fold-flat functionality
Inventor: SMUK WOJCIECH
IPC: B60N2/90
Filed: 2002-06-13
Abstract: A hinge is disclosed, which forms part of a vehicle seat which includes a seat cushion and a cushion plate attached thereto. The fixed part of a rotary recliner, having a handle extending therefrom, is mounted to the cushion plate. An idler plate is mounted to the movable part of the recliner, for rotation therewith. A sector plate, which carries a seat back, has a first position relative to the idler plate, and is lockable thereat by a latch, for rotation with the idler plate under control of the handle. This permits the seat back to be pivoted to a preferred seating position via the recliner when the latch is engaged. When the latch is disengaged, the sector plate is forwardly rotatable, relative to the idler plate, from the preferred position. A spring biases the latch to re-engage the sector plate upon rearward rotation thereof back to its first position.

Filed: 2001-03-14
Abstract: A hyper encoder module encodes a block of data having a plurality of sub-blocks. Each sub-block includes a plurality of systematic block code codewords. A parity sub-block is added to the block.  The parity sub-block is a first sub-block rotated by a predetermined number of bits. Each subsequent sub-block in the n-dimensional block is rotated by an appropriate number of bits and bit-wise XORed. An encoder method and apparatus which includes the hyper encoder module receives the block of data. A row of the block is immediately output and encoded by a first module according to a first encoding scheme. A column is encoded by a second module according to a second encoding scheme. A second set of encoded data is generated, iteratively updated and output by the second module. The hyper encoder module hyper-diagonally encodes the information bits as described above and then output.
