Patent CA-2464964-A1 (CA)
Inventor: HEARN TIMOTHY CHARLES
IPC: F15B11/028
Filed: 2004-04-21
Abstract: The invention is intended to reduce steady state gas consumption of a pneumatic device such as a controller having a bleed nozzle. The instrument comprises two zero-bleed modules, more particularly a low pressure regulating module and a pressure amplifying module. Both modules are supplied with power gag from an existing line pressure regulator assembly.    The pressure of one stream of power gas is reduced through the low pressure regulating module and is introduced into the controller. Gas pressure from the controller output is transmitted to the receiving port of the pressure amplifying module. A second stream of power gas goes to the pressure amplifying module and is used in conjunction with the signal from the regulating module utilizing a multiplier ratio such as 1:6. The amplifying module outputs a proportional control signal that is then transmitted to a controlled device, such as a pressure control naive in a pipeline.

Patent CA-2475569-A1 (CA)
Inventor: READER JOHN R JR
IPC: G01N35/04
Filed: 2004-07-22
Abstract: The present invention relates to apparatus, systems, and methods for opening an autosampler sealed sample pan prior to TGA testing. The sealed sample pan comprises a pan, cover, and bail. A notch is formed in the seal sample pan cover. The cover can be opened by applying a concentrated force to the inside of the notch with a punch element integrated into the autosampler. This causes the center disk portion of the cover to be partially sheared and the sealed sample pan to be opened. It also prevents the punch element from touching the sample. A force sensor is used to determine if the cover has been opened. If the cover has been opened, then the sample pan is loaded to the TGA balance. If the cover has not been opened, the autosampler will not load the pan and will automatically move to the next sealed sample pan.
