Patent CA-2337818-C (CA)
Inventor: KERRES JOCHEN
IPC: H01M8/1023
Filed: 1999-03-26
Granted: 2011-05-31
Abstract: The invention relates to a method for producing nitrated and optionally sulphonated and aminated and optionally sulphonated aryl main chain polymers, in addition to aryl main chain polymers thus modified. Aryl main chain polymers (e.g. (1)) are nitrated by dissolving them in expensive, toxic and environmentally damaging solvents. Aryl main chain polymers which are selectively and simultaneously nitrated and sulphonated were not previously known in literature. The inventive method makes it possible to produce low-cost nitrated (and optionally sulphonated (2)) or post-reduction aminated (and optionally sulphonated) aryl main chain polymers without any organic solvents. Nitration (and optionally additional sulphonation) of the aryl main chain polymers occurs by dissolving them in concentrated sulphuric acid and by adding desired amounts of nitric acid at different temperatures and with different agitating times. The reaction can be carried out (a) as a two-step process: nitration followed by isolation of the polymer, then optional sulphonation and (b) as a single-step process: simultaneous nitration and sulphonation (2). The nitrated (or additionally sulphonated) polymers can then be reduced to form aminated (or additionally sulphonated) polymer. The polymers can be reacted with other polymers to form polymer blends. The polymers and polymer blends can be used as ion conducting membranes in electro membrane processes.

Abstract: A faucet assembly includes a body, a pressure-stabilizing device, a temperature adjustment device, a flow-rate control valve, and a faucet end unit. The pressure-stabilizing device is disposed between a pair of cold-water and hot-water input passages and a pair of cold-water and hot-water output passages so as to permit flow of cold water and hot water from the cold-water and hot-water input passages into cold-water and hot-water inlets in the temperature adjustment device through the cold-water and hot-water output passages at the same flow rate even when the water pressures in the cold-water and hot-water input passages are different. The cold and hot water flow from the cold-water and hot-water inlets to a water discharge port at a ratio, which can be selected by rotating a rotary knob, thereby feeding a selected temperature of water to the faucet end unit. The flow-rate control valve is disposed between the temperature adjustment device and the faucet end unit.      As such, the temperature of water from the faucet end unit can be controlled independently of the flow rate.

Title: Apparatus and method for stripping filmic casings from products
Inventor: THOMSON TERRY W
IPC: A22C11/00
Filed: 2001-05-08
Granted: 2010-01-26
Abstract: The invention provides an apparatus and a method for processing packages made up of a filmic casing containing a product, to separate the casing from the product for subsequent further processing of the product. The package is moved through a series of steps to first weaken the casing, and then a leading end of the moving casing is gripped and the end of the casing is moved away from the product. As a result the casing is stripped off the product as the weakened casing opens and the product continues to move.

Abstract: An energy storage device (10) comprising a large scale flywheel supported by a fluid bearing (44, 45). The flywheel has a diameter greater than 100 feet and a concrete, steel-reinforced rim (1 1) weighing in excess of 1000 metric tons. In off peak periods the apparatus is operated as a motor with energy input causing the r im (11) to rotate up to a predetermined speed and to maintain rotation at that speed in the power take off mode. During peak powe r time periods, the operation of the electrical circuitry is reversed and the flywheel generates electrical energy which is delivered by the storage device to the power grid. As energy is delivered, the rotational speed of the flywheel diminishes and gravitational waves capable of being shaped and modulated are generated The unique electrical circuit utilizing coils (26) and power transistors (30 , 32) under computer software control facilitates operation as a peak power energy storage device or as a gravitational wave generator.

Title: Preserving consistency of passively-replicated non-deterministic objects
Inventor: FELBER PASCAL
IPC: H04L12/16
Filed: 2000-12-21
Granted: 2009-05-05
Abstract: Techniques are provided for executing an operation in which a client invokes a replicated object. According to one technique, a primary replica of a replicated object receives a first request from a client, wherein the first request includes a request identifier. Rather than immediately attempting to process the request, the primary replica determines whether a record exists that corresponds to the request identifier. If a record exists that corresponds t o the request identifier, then the primary replica responds to the first request with a reply associated with the record. If no record exis ts that corresponds to the request identifier, then the primary replica performs the steps of: starting a transaction; as part of the transaction, processing the request; as part of the transaction, storing a record associated with the request identifier and a reply to the request; committing the transaction; and delivering the reply to the client. The client may itself be a replicated object. If the client i s nondeterministic, then the transaction initiated by the primary replica may be a nested transaction relative to a transaction executed by th e client, or be executed as part of the same transaction as the client. If the transaction executed by the primary replica is executed as pa rt of the same transaction as the client, then a savepoint may be established before the primary replica processes the request, so that a failure will not necessarily require all processing performed by the client to be rolled back.

Title: Judgment lock for occupant detection air bag control
Inventor: THOMPSON GREGORY T
IPC: B60N2/90
Filed: 2003-04-25
Granted: 2007-07-17
Abstract: Systems and methods for controlling the sensing of an occupant in a seating area are provided. The occupant is characterized as one of an adult, child or other category. One characterization change parameter, such as a hysteresis time period or thresholds for characterization, is applied for a first time period. After that time period, the characterization change parameter is changed. For example, if the characterization stays the same for ten seconds, the hysteresis is changed from five to ten seconds. As another example, if the characterization stays the same for one minute, the thresholds associated with that characterization are broadened to decrease the likelihood of a change in characterization. In some systems and methods, a confidence parameter or probability associated with the characterization is used to control the changes of the characterization change parameter. In some systems and methods, the characterization change parameter is reset in response to one of (a) a no occupant characterization or (b) characterizing the occupant as a different one of the at least two categories consecutively for a current hysteresis time period.
