Patent CA-2638788-A1 (CA)
Inventor: GUTIERREZ-ROCCA JOSE
IPC: C08J9/28
Filed: 2004-04-14
Abstract: Hydrogels, and especially superporous hydrogels are dehydrated by subjecting them to lyophilization such that a water/hydrogel weight/weight ratio of from 0.005 to 0.1, thereby stabilizing them; the hydrogels may in particular, be produced using an ion--equilibration technique. Anionic polysaccharides are included in the hydrogel reaction mixture and cations are introduced either during or after hydrogel formation.  Properties of the resulting hydrogel can be subsequently adjusted by treating the cation complexed gel with a different cation or cation mixture under equilibrating conditions.  It has been found that by properly adjusting the cations and the sequence in which they are used in the equilibration process, superporous hydrogels can be formed that are highly absorbent while maintaining favorable structural properties, including strength, ruggedness, and resiliency. It has also been found that applying the dehydration conditions to them after their formation further stabilizes the hydrogels.

Title: Gas turbine compressor water wash control of drain water purge and sensing of rinse and wash completion
Inventor: WAGNER THOMAS
IPC: F16L55/07
Filed: 2008-10-07
Abstract: A purge drain valve including a spool spliced in a fluid line includes a control valve and an actuator coupled to the control valve for regulating fluid flow. During a washing operation, fluid flows between a supply end and a delivery end of the spool, and during a purging operation, the control valve diverts fluid entering the supply end from the delivery end towards a drain leg.  A washing system includes a fluid supply coupled to an input of a wash delivery system and a delivery line coupled to an output of the wash delivery system. The purge drain may be spliced into the delivery line to permit fluid to reach a wash apparatus during a washing operation and to prevent fluid from reaching the wash apparatus during a purging operation. A  rinse cycle sensor apparatus may be employed to indicate to an operator if a washing operation is complete based upon a conductivity of fluid exiting from a device being washed.

Title: Water refilling device for water saving toilets
Inventor: LO TSUNG-YI
IPC: E03D11/00
Filed: 2009-05-19
Abstract: A quantitative refill device is mounted on the top end of an overflow pipe in a water tank of a water saving toilet and comprises a first pipe, a second pipe and a float device. The second pipe defines a second chamber. Initially, water flows to the overflow pipe to create a water closing through a water flow passage between the second pipe and the float pipe, especially a conical passage defined between a conical surface of the second pipe and a conical portion of the float device. Meanwhile, the float device moves upward along with the rise of the water level of the second chamber to close the conical passage. By the time the conical passage is closed, the water closing is formed, and the refilled surplus water will overflow into the water tank, thus creating a quantitative water refilling effect.
