Patent CA-2405338-A1 (CA)
Title: Connection device
Inventor: MCNEIL ALEXANDER MCKECHRAN HAR
IPC: F16L25/00
Filed: 2001-04-17
Abstract: A connection device for fitting to a member, particularly to a corrugated flexible pipe (146,246,446) formed with a series of spaced annular grooves, the device comprising first and second tubular bodies (10, 11) coupled together, in use, with the pipe received in an open end of tHE first body (10). The first body has a plurality of resilient lugs (14) with respective inwardly directed projections (17) at the ends thereof to be received in one of the said grooves to grip the pipe. The two bodies can be relatively angularly moved between a neutral position of the device, where the pipe is retained by the resilience alone of the lugs, an unlocked position, where the lugs are released from the pipe, and a locked position, where the lugs are forced into locking engagement with the pipe, movement of the lugs being controlled by cam formations (29) extending from the end surface of the second body (11). In other embodiments the bodies can have a rotation lock in said locked position and/or neutral position, and/or a lock to prevent outward movement of the lugs when the bodies are in the locked position.

Title: Process for preparing chitosan particles
Inventor: WISNIEWSKA-WRONA MARIA
IPC: A01N43/16
Filed: 2001-05-10
Abstract: Disclosed is a process for producing particles of the modified carbohydrate polymer chitosan. Such chitosan particles are "activated" as a consequence of the specific steps used in the process. The process involves precipitation of dissolved chitosan from an acid solution thereof by the step-wise addition of neutralizing agent to the solution. A partial neutralization is carried out under shear agitation to form a continuous gel phase having a pH within the range of 5.0 to 6.9. This partially neutralized chitosan gel phase is then further subjected to shear agitation for at least 10 seconds to homogenize the gel phase. The homogenized gel phase is then further neutralized under shear agitation to a pH of above 6.9 to form a gel-like suspension of discrete chitosan particles. Chitosan particles in this form are useful in a number of contexts including, in particular, in the area of plant care.

IPC: C07C37/08
Filed: 2001-08-07
Abstract: Injection of even very small amounts of supplemental water to the spent-air stream at points upstream from the heat exchanger cooler(s) used in processing spent-air streams from a cumene-to-phenol process allows these heat exchanger coolers to act as both extractors and condensers. It is therefore possible to recover from the heat exchanger cooler a methanol/water condensate, thereby substantially reducing the amount of methanol in the spent-air stream prior to discharge. Thus, known methods of manufacture of phenol from cumene in which an oxygen-containing gas stream is passed through liquid cumene to produce an oxidate product and a spent-air stream comprising methanol and cumene and a saturating amount of water; and in which the spent-air stream is passed through one or more heat exchanger coolers and a carbon bed prior to discharge can be improved.

Title: System and method for telephone call reorigination
Inventor: PANELLI LEONARDO
IPC: H04M3/42
Filed: 2003-08-08
Abstract: A transparent call reorigination process whereby a telephone call between an origin and destination can be routed as a two-leg call through a third point. A call controller captures the destination dialing input from the subscriber at the origin telephone and communicates that to a sell rcorigination service provider via a separate data network.   The provider dials and connects two telephone call legs, one from the provider premises back to the origin and one from the provider to the destination. These two legs are connected through the provider's premises and equipment, yielding a connection between origin and destination. The system operates transparently to the subscriber, without the delays or inconveniences of previously known reorigination methods.
