Patent CA-2442793-A1 (CA)
Inventor: CARMICHAEL LISA M
IPC: B01J23/90
Filed: 2003-09-26
Abstract: The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst.  Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. The re-dispersion technique involves the formation and removal of carbonyls with the active metals. The carbonyl formation and removal effectively re-disperses the catalyst metal.

Title: Distributing hydrokinetic energy in fluids
Inventor: FREI ALEXANDRA SARAH
IPC: B01F5/02
Filed: 2002-07-10
Abstract: Each immersed jet creates turbulences as a result of the resistance of the medium in which it is immersed and at the end of its effective range the complete introduced energy is broken down into turbulent flows. These turbulent flows observed as a whole are local, thus are small-scale. It is however indeed these small-scale turbulences which have a strong eroding effect and it is the object of the invention to produced as high a number as possible of small-scale turbulences and to distribute these over a large volume. Large volume is to be understood as for example 3000-4000 m3 on a surface of 2000 m2 and a height of 2 m as is the case with a storage tank of 50 m diameter and a liquid column of 3 m. The problem thus lies in the optimal distribution of the introduced energy.

IPC: A61P31/10
Filed: 2002-10-22
Abstract: A method of screening a drug acting on cell wall which involves: (1) the step of culturing a microorganism immobilized on cell wall with the use of a reporter protein as a GPI anchor protein in the presence of a test drug acting on cell wall; (2) the step of analyzing a sugar chain originating in the reporter protein released into the liquid culture medium of the microorganism;  and (3) the step of presuming the action point of the drug on the cell wall based on the data of the sugar chain originating in the reporter protein obtained in the above step (2). By easily and adequately judging the action points of drugs having an inhibitory effect on cell wall, a cell wall-acting drug acting on a specific action point can be efficiently screened.

IPC: E05F15/00
Filed: 2004-05-27
Abstract: A movable barrier operator can use (11) a first technique to prevent an excess application of force during controlled movement of a movable barrier (43) and at least a second technique (12) to similarly prevent an excess application of force during such movement. Both techniques can then be utilized to determine (13) when an application of excess force may nevertheless occur and not be reasonably avoided. In one embodiment, two techniques (21 and 22) can be used to detect force as applied during movement of the movable barrier and such information can be used to determine (23) whether applied force is being reliably indicated. In another embodiment, travel limit information (51), travel information (52) and travel history information (53) are utilized to assess whether normal operation of the movable barrier operator should be over-ridden (54) due to a possibly expression of undue force.
