Patent CA-2306066-A1 (CA)
Title: Air desiccant canister
Inventor: STROPE CLAUDE F
IPC: B01D53/26
Filed: 2000-04-18
Abstract: A desiccant filter of the spin-on type is provided with an aluminum cast baseplate which has an aperture formed therein for receiving a pressure relief valve. The baseplate is secured to a sheet steel canister by a hemming connection which folds the end of the canister around the rim of the baseplate. The inlet port for receiving wetter air and the outlet port for returning drier air are located in the baseplate. The inlet port may be located inside the outlet port or alternatively the outlet ports may be located inside the inlet ports.  A relief valve is mounted in the aperture of the baseplate to relieve excessive pressure build up in the filter and the air braking system. The pressure relief valve includes a valve body, a compression spring and a plunger. The valve body includes an opening and the plunger includes plug which extends into the opening to prevent formation of a deposit area where water and other contaminants may be deposited. Regardless of whether the outlet port is located inside the inlet ports or likewise the reverse, the pressure relief valve is always located in a position where it receives relatively dry air thereby better preventing the possibility of oil and water from freezing in the relief valve. The desiccant bed is compressed in a way that minimizes the amount of gaps between pellets and also minimizes the amount of rubbing between pellets thereby reducing the amount of desiccant dust produced.

Title: A method and system for pattern recognition and processing
Inventor: MILLS RANDELL L
IPC: G06V10/70
Filed: 1998-12-23
Abstract: The present invention provides a method and system (1) for pattern recognition and processing. Information representative of physical characteristics or representations of physical characteristics is transformed into a Fourier series in Fourier space (12) within an input context of the physical characteristics that is encoded in time as delays corresponding to modulation of the Fourier series at corresponding frequencies. Associations (14) are formed between Fourier series by filtering the Fourier series and by using a spectral similarity between the filtered Fourier series to determine the association based on Poissonian probability. The associated Fourier series are added to form strings (16) of Fourier series. Each string is ordered by filtering it with multiple selected filters to form multiple time order formatted subset Fourier series, and by establishing the order through associations with one or more initially ordered strings to form an ordered string. Associations are formed between the ordered strings to form complex ordered strings (18) that relate similar items of interest.
