Patent CA-2425975-A1 (CA)
Inventor: DAI XIANGFENG
IPC: B01J20/34
Filed: 2001-10-19
Abstract: A method for removing a first sorbate (21) having a first desorption activation energy and a second sorbate (21) having a second desorption activation energy from a sorbent (18), involves a two-stage desorber (10). I n a first stage (12), the first sorbate (21), second sorbate (21) and the sorbent (18) are contacted with a stripping fluid (32) having a first temperature sufficient to separate the first sorbate (21) in a vapor phase from the sorbent (18). In a second stage (14), the second sorbate (21) and t he sorbent (18) is heated to a second temperature higher than the first temperature to separate the second sorbate (21) in a vapor phase from the sorbent (18). The second sorbate (21) can then be condensed to a liquid phas e and sold to offset the costs of the process. Heating in the second phase (14 ) can be facilitated by the introduction of microwave or infrared energy (61 d ) for stripping the second sorbate (21) from the sorbent (18). Use of the microwave or infrared energy (61 d) can be facilitated with a purging gas (47), which can also be heated to function as a stripping gas (47). An associated apparatus includes two desorption chambers (30, 45) or alternatively a single desorption chamber for use in both stages.

Title: Fluid actuator rotor for hinged vehicle safety devices
Inventor: BERNARD EDWARD
IPC: B60Q1/50
Filed: 2003-05-01
Abstract: A fluid actuator attaches a hinged safety device to a vehicle and pivots the hinged safety device between retracted and extended positions. The housing of the actuator has a base and a removable cover. A sub-assembly is attached to the base. The subassembly includes a generally planar base member with integral right cylinder, lever arm pivot support and stop posts. A piston slides in the right cylinder and forms a fluid chamber between the piston and a closed end of the right cylinder that is fed through a passage through the closed end of the cylinder. A lever arm is pivotally attached to the lever arm pivot support at one end for pivotal movement between retracted and extended positions, the lever arm extending over the cylinder and having a lip at an opposite end that is spaced from the right cylinder. A pivot arm engages the top of the piston at one end and the lever arm at an opposite end to transfer motion from the piston to the lever arm. The lever arm transfers motion to a rotor that is rotationally mounted in the housing for movement between retracted and extended positions. The rotor has a spool at each end and an eccentric arm between the spools at the respective ends of the rotor that engages the lip of the lever arm. A torsion spring encircles each spool with one end engaging the rotor and an opposite end engaging a stop post so that the eccentric arm is biased against the lip of the lever arm and the rotor and the lever arm are biased to their respective retracted positions. The rotor and torsion springs are formed into a pre-assembled unit for the sub-assembly by preload spring clips.

Title: Transmitting apparatus and transmission method
Inventor: MIYOSHI KENICHI
IPC: H04B1/707
Filed: 2003-02-17
Abstract: A randomizing unit (101) makes the number of 1 and the number of 0 of the data identical. A coding unit (102) performs coding of the data in which the number of 1 and the number of 0 have been made identical. An HS-DSCH modulation spread unit (103) performs multinary modulation of the coded data and then performs spread processing of the data by using a spread code. On the other hand, a common known signal is subjected to multinary modulation in a CPICH  modulation spread unit (104) and the spread processing by using a spread code.  The common known signal subjected to the spread processing in the CPICH  modulation spread unit (104) is multiplexed with the data which has been subjected spread processing in the HS-DSCH modulation spread unit (103) by a multiplexing unit (105). The transmission signal multiplexed is transmitted from a radio transmission unit (106). Thus, with a simple circuit configuration, it is possible to accurately obtain a reference point of the I-Q plane.
