Patent CA-2204543-C (CA)
Title: Revetement bioactif pour proteger des produits agricoles recoltes
Inventor: WILSON CHARLES L
IPC: A23L1/00
Filed: 1995-10-31
Granted: 2008-02-12
Abstract: Une composition de revêtement bioactive comprend une matrice de chitosan modifié contenant des levures agissant comme des antagonistes vis-à-vis d'agents qui sont des pathogènes pour des produits agricoles récoltés. On ne pouvait pas s'attendre à ce que les chitosans puissent être utilement combinés à des levures antagonistes, à cause de leurs propriétés antifongiques. Toutefois, on a trouvé que certaines levures antagonistes étaient compatibles avec des chitosans modifiés et pouvaient être utilisées pour inhiber la décomposition et pour moduler le mûrissement. La combinaison de chitosans modifiés avec les antagonistes permet de tirer profit des propriétés antifongiques et des propriétés sélectives du chitosan, ainsi que de l'activité antagoniste des levures. La complexité du mode d'action résultant de l'utilisation de différentes combinaisons rend difficile l'apparition d'une résistance des pathogènes et assure une protection particulièrement sophistiquée contre des maladies.

Abstract: Tête d'abattage à pince collectrice possédant un mécanisme servant à retenir plusieurs arbres obtenu en élevant le mécanisme servant à retenir les arbres pour le prolonger vers l'extérieur et vers l'arrière au-dessus des dents de la scie. Les arbres sont ramenés à partir de la zone de coupe avant, au haut d'une petite rampe dans le mécanisme servant à retenir les arbres, par un bras collecteur, et sont maintenus là par un bras de retenue. Le bras collecteur et le bras de retenue pivotent, de préférence, dans le même axe, sur le côté opposé de la tête à partir du mécanisme servant à retenir les arbres et passent au-dessus du moteur de la scie pour ramener les arbres sur une distance considérable vers l'arrière, c.-à-d., au moins derrière une ligne latérale imaginaire traversant l'axe de la scie. La plaque de butée est évidée au-dessous de la partie supérieure du trait de scie, ce qui permet d'incliner la tête d'abattage légèrement vers l'avant pour progresser de manière continue d'un arbre à l'autre.

Patent CA-2228227-C (CA)
Inventor: VAN DER PLAATS JOHANNES CHRIST
IPC: H04B10/17
Filed: 1998-01-27
Granted: 2002-03-26
Abstract: The dynamic gain control system includes a pump source providing pump light. The dynamic gain control system measures a certain portion of the input pump light into the optical amplifier and measures a certain portion of the output pump light from the optical amplifier. The dynamic gain control determines the pump light loss based on the input pump light and output pump light measurements. Based on the pump light loss, the dynamic gain control system maintains the pump light loss relatively constant (for example 0.1 dB) independent of the number of input channels and their relative powers (for example, input channel powers of-50 dBm to 10 dBm) by providing feedback to control the output pump light. In doing so, the dynamic gain control system maintains the inversion level of the optical amplifier. A relatively constant inversion level corresponds to only small variations in the gains of the input channels (multi-channel gain) as a result of changes in the input channels to the optical amplifier.

Title: Method and apparatus for testing and sampling open-hole oil and gas wells
Inventor: SCHULTZ ROGER L
IPC: E21B49/08
Filed: 1998-01-30
Granted: 2004-08-10
Abstract: Method and apparatus for testing and sampling open-hole oil and gas wells. The apparatus comprises a packer, a surge chamber, a closure valve which may be opened to flow fluid into the surge chamber, and a sampler. The surge chamber may be one of a pair of surge chambers, and the closure valve may be one of a pair of closure valves so that two surges may be carried out prior to obtaining a fluid sample in the sampler. In operation, the packer is placed in a set position by setting down weight. The closure valves are also actuated when weight is set down. The first closure valve has a first predetermined time delay before opening so that the packer may be set, and the second closure valve has a second predetermined time delay so that the packer may be set and the first closure valve opened before a fluid sample is captured. By opening a vent tool at an upper end of the uppermost surge chamber, formation fluid may be forced back into the formation or zone of interest by a bull-heading operation. In a preferred embodiment, portions of the apparatus are detachable in the event of sticking of the apparatus in the well. In the method of the two-surge test, a clean fluid sample for capturing in the sampler is provided. All of the steps are carried out without flowing fluid to the surface.
