Patent CA-2195701-A1 (CA)
Title: Torque-resistant slip
Inventor: LEMBCKE JEFFREY J
IPC: E21B33/129
Filed: 1997-01-22
Abstract: The invention relates to a slip design with substantially longitudinally oriented wickers, which can be used alone or in combination with transversely oriented wickers, to secure a downhole tool, such as a bridge plug or packer, against rotational forces, such as those imparted from a whipstock, as well as longitudinal forces, such as those ultimately delivered by pressure fluctuations from uphole or downhole. The longitudinally oriented wickers are further cammed against the casing since any imparted torque on the packer body contacts a corner or edge of the slip, imparting to it a camming action making it dig further into the casing surface.

Les extrémités proximales des éléments intérieur et extérieur sont reliées à un actionneur les déplaçant axialement l'une par rapport à l'autre. L'extrémité distale de l'élément extérieur est reliée à un cylindre présentant une arête distale tranchante ou à un ensemble mâchoires, tandis que l'extrémité distale de l'élément intérieur est reliée à l'autre. L'ensemble mâchoires comporte une paire de coupelles de mâchoires opposées de préférence dentelées dont chacune est reliée par un bras souple à une base. Les bras sont courbés de manière à se tenir dans des plans coupant l'axe de la base et pour maintenir les mâchoires écartées l'une de l'autre. La base est montée dans le cylindre et les mouvements relatifs de l'ensemble mâchoires et du cylindre tirent les bras dans le cylindre et referment les mâchoires pour mordre. L'effet de morsure est renforcé puisque les arêtes tranchantes des mâchoires se situent dans un plan coupant celui où se trouve la partie distale du bras des mâchoires. Il l'est également par la présence à la surface extérieure des mâchoires d'une came de fermeture qui s'engage dans le cylindre lorsque les mâchoires se referment. Les arêtes tranchantes présentent une surface lisse face à l'intérieur d'un endoscope et les cames de fermeture empêchent le manchon de coulisser sur les mâchoires et de les dépasser.

Title: Communication system of portable communication terminal, incoming call control system of portable communication terminal and incoming call notifying device of portable communication terminal
Inventor: NAKAZATO KOUJI
IPC: H04M19/04
Filed: 1996-12-26
Abstract: A system intended to eliminate erroneous operations of the vibrator, a drawback of mobile terminals of the conventional independent vibrator method. The system comprises communication mobile terminals capable of communicating with other terminals through radio communication while they are moving; and peripheral devices designed to perform predetermined operations through radio communication between the mobile terminals and the peripheral devices. For radio communication between the mobile terminals and the peripheral devices, the apparatus employs time division multiplexing that exchanges signals by carrying data in time slots. In the time division multiplex, the mobile terminals use time slots of time bands other than those that the mobile terminals use for sending radio signals to base stations to send radio signals to the peripheral devices. This allows the mobile terminals to send radio signals to the peripheral devices without being interfered with by the radio signals transmitted by the mobile terminals to the base stations.

Title: Gate outlet structure for hopper railcar
Inventor: FORBES JAMES W
IPC: B61D7/02
Filed: 1998-01-29
Abstract: A hopper car gate outlet structure is has one part connected to the hopper near the hopper outlet, the part extending outwardly from the tapered hopper wall to provide a mounting for a gate outlet. The mounting includes a land specifically oriented to mate with the outlet gate, and an outer portion for connection to a reinforcing formation. In one example the reinforcing formation is bent back toward, and attached to the hopper. In all examples the reinforcing formation is shaped to facilitate access to the fastening hardware used to mount the outlet gate to the hopper. The reinforcing formation discourages deformation of the land, and in so doing discourages the migration and collection of material from the hopper discharge in the outlet, such that contamination of subsequent loads of material in the hopper is also discouraged.

Title: Methods for isolating polyhydroxyalkanoates from plants
Inventor: MARTIN DAVID P
IPC: C08G63/89
Filed: 1996-10-23
Abstract: Methods are provided for separating polyhydroxyalkanoates ("PHAs") from plants, such as transgenic oil crop plants. The methods advantageously permit both the oil and the PHAs to be recovered from the plant biomass. To isolate the PHAs, in one embodiment, a biomass derived from an oil crop plant is pre-processed, for example by grinding, crushing or rolling. The oil then is extracted from the biomass with a first solvent in which the oil is soluble and in which the PHAs are not highly soluble to remove the oil. The biomass then can be extracted with a second solvent in which the PHA is soluble, to separate the PHA from the biomass. Alternatively, the PHA-containing biomass is treated with a chemical or biochemical agent, such as an enzyme, to chemically transform the PHA into a PHA derivative.  The PHA, derivative then is separated from the mixture using, for example, a physical separation process such as distillation, extraction or chromatography. Advantageously, using the method, the plant oils, the PHAs and PHA derivatives can be recovered and purified on a large scale from oil containing plants such as transgenic oil crop plants.
