Patent CA-2413463-A1 (CA)
Title: Heat-transfer fluid containing nano-particles and carboxylates
Inventor: LIEVENS SERGE
IPC: C10M101/02
Filed: 2001-06-13
Abstract: The use of sub-micron particles (nano-particles) and carboxylates for improving the heat-exchange characteristics of heat-transfer fluids or antifreeze coolants. The carboxylates form a stable physisorbed- or chemisorbed carboxylate protective layer on metallic nano-particles that does not hinder heat-transfer. The combination of carboxylates and metallic nano-particles provide excellent corrosion protection, improved heat-transfer and enhances the stability of the sub-micron particles (nano-particles) in suspension. Sub-micron particles (nano-particles) treated with carboxylates to form a chemisorbed carboxylate protective layer are used in a heat transfer fluid or a lubricant or hydraulic fluid or soap.

Title: A pig for detecting an obstruction in a pipeline
Inventor: SAVARD DONALD D
IPC: G01B5/12
Filed: 2002-12-23
Abstract: An obstacle detecting pig for preliminary inspection of a section of a pipeline is disclosed. It travels through the section and determines if there are any restrictions that exceed industry guidelines or might damage other pigs that require the full bore of the pipe. A resiliently deformable disc-shaped detector has a plurality of segments, each operatively connected to a separate device generating an electrical signal. A  balast retains the detector segments continuously in the same position relative to a vertical reference plane coincident with the axis of the pipeline to improve the indication of the location of an anomaly circumferentially of the pipeline. In a second embodiment, the detector has the structure of resilient adjacent layers separable from each other upon encountering an obstacle. The components generating the electric signal are fully embedded in the respective layers.
