Patent CA-2354088-A1 (CA)
Title: Photo switching device
Inventor: CHENG CHI CHING
IPC: H05B37/02
Filed: 2001-07-25
Abstract: A photo switching device includes first and second terminals respectively coupled to a power source and a load. A bi-directional current routing circuit including a rectifying bridge is connected to the first and second terminals to receive electricity from the first and second terminals and has positive and negative output terminals. A switching/driving circuit is connected between the positive and negative output terminals for selectively conducting an output current of the bi-directional current routing circuit from the positive output terminal to the negative output terminal. The switching/driving circuit includes a silicon controlled switching device having a gate coupled to and controlled by a controlling circuit to switch between open condition and closed condition. The controlling circuit includes a photo detecting device connected to a gate of a gate controlled device. The gate controlled device has an output coupled to and controlling the gate of the silicon controlled switching device. When the photo detecting device detects surrounding light, the output of the gate controlled device is switched from a logic high state to a logic low state which in turn changes the silicon controlled switching device from the closed condition to the open condition thereby cutting off the output current from the positive output terminal to the negative output terminal. A variable resistor is connected in serial to the photo detecting device for sensitivity adjustment. A voltage regulation circuit is combined with the controlling circuit in parallel with the photo detecting device for voltage regulation purposes.

Patent CA-2358920-A1 (CA)
Title: A method of testing a cell sample
Inventor: SHINE THOMAS ADAM
IPC: G01N33/48
Filed: 1999-12-24
Abstract: The present invention measures agglutination using a process which is capable of testing how tightly agglutinated cells are bonded by measuring how much force is required to separate them. By causing red cells which are approximately biconcave discs to sphere, the effective surface area available for bonding diminishes. Sphering a cell increases the space between antigen binding sites and increases the mean distance across which bonding occurs. As the surface area available for bonding between cells decreases as cells sphere they lose bonding strength, thus allowing clumped cells to separate. By recording the inducing pressure and the number of cells (or quantities related to it) as they change with respect to the inducing pressure, agglutination can be detected, quantified and monitored. This provides a simple but effective test for blood grouping and cross-matching by introducing an appropriate source of antibodies and detecting whether or not agglutination occurs.

Title: Cleaning using welding lances and blasting media
Inventor: CHERICO STEVE
IPC: F27D25/00
Filed: 2000-02-11
Abstract: It is possible to clean high temperature (over 400, e.g. over 1000, degrees F) surfaces in a time and cost efficient manner by using a liquid-cooled ceramic welding lance (11) to direct (at super-atmospheric pressure) a blasting media at the surfaces to be cleaned. The blasting media (23) is preferably combustible at the temperature of the environment surrounding the surfaces, and may include one or more organic agricultural abrasive materials (preferably black walnut shells) as the sole or primary constituent. Blasting may be practiced by directing the media at the surfaces to be cleaned (15) at a pressure of between about 40-100 psi, for example continuously for as long as is necessary (e.g. more than 30 minutes), without any need to remove the lance (11) from the environment. The method is desirably practiced to clean, while in operation or in situ, metal surfaces having scale buildup which adversely affects the ability of the metal surfaces to transfer heat, reheat tubes, process tubes, furnace surfaces, or the like.

Filed: 2002-04-26
Abstract: A self-regenerating softener pack used for the reduction of static and the softening of garments. This pack comprises a non-woven spunbonded polyester pouch with a flaked/ solid softener/ antistatic compound. The pouch is placed in the dryer with the garments/ fabrics. The softener/ antistatic compound in the bag melt during the drying cycle and permeate through the non-woven spunbonded polyester pouch hence coating its outer layer. This layer enters into contact with the garments reducing static, imparting softness and smooth handle to the garment.   At the end of the cycle, the pouch is kept for future drying cycles. The same process reoccurs with each cycle until the total quantity of the softening/ antistatic ingredient is depleted. One pouch containing approximately 100 grams of active ingredient can last for up to 100 domestic size load cycles. This eliminates the need for change of softener sheets, softener addition during the rinse cycle in the washer and reduces waste.   The softener pouch can be complemented with various scents, which can be sprayed onto the pouch before drying cycle. The scent is transferred to garment during the cycle.

Title: Protection of labile proteins during iodine disinfection
Inventor: SHANBROM EDWARD
IPC: A61L2/16
Filed: 1999-10-22
Abstract: Mixtures of iodine source resin with iodine capture resin have been found to provide effective disinfecting of protein-containing solutions such as plasma. These mixtures can be used in a chromatographic manner to effectively disinfect solutions while causing minimal damage to labile proteins such as clotting factors. Mixed resins containing equivalent amount of iodine source and iodine capture (50:50) are effective in many cases. If protein damage is still occurring, the ideal mixture may be one containing a lower amount of iodine (e.g. 25:75 or even 5:95). If disinfecting properties prove inadequate, ratios can be increased (e.g. 80:20). Surprisingly, the mixed resins also spare tissue components such as red blood cells and platelets. In some cases mixed resins are even useful in a batch procedure where the resin is removed by centrifugation or filtration at the end of a treatment period.
