Title: Rotary metering valve for abrasive media
Inventor: JANUSZ MARK A
IPC: B24C7/00
Filed: 1993-07-20
Abstract: (57) ABSTRACT:           A standard industrial pressure blasting paint-stripping apparatus works with abrasive media and commpresed air, which is combined in the mixing chamber of the media flow valve located directly under the pressure pot and conneted to the push line and the conveying line. This equipment works quite well providing the pres-sure pot and the mixing chamber have an equal pres-sure.  The moment a pressure unbalance occurrs, (higher pot pressure), a conveying line will receive more media than is requested or less media if the mixing chamber pressure is higher.  Unpredictability of such a system is not acceptable when blasting technology is utilized for paint stripping of a surface such as wood, aluminum, glass, etc., due to potential damage of said surface.  In this inven-tion a standard media flow control valve is replaced with the "ROTARY METRING VALVE" for abrasive media. This improvement proves perfect control of media flow regardeless of any pressure diff rential which might appear during the blasting operation, there-fore, assuring full control of the blasting process. Due to this invention the dry-media blasting tech-nology can be applied in an area with paint strip-ping of furniture, masonary or wood constraction type homes, fibreglass or aluminum vechicles, boats, ect. is being done.

Abstract: Data stored in a data base (21) includes crisp numbers expressed by definite numerical values, fuzzy numbers expressed by attaching "about" to numerical values, and fuzzy labels represented by fuzzy language.          Status codes are used to distinguish these types of data, and data is stored in the data base (21) upon attaching the status codes thereto.  Membership function data accessed using data and the status codes attached thereto is stored in a fuzzy data dictionary (22).  When a retrieval condition has been given, data related to this retrieval condition is retrieved in the data base (21).  If this data is data involving a fuzzy concept, the membership function data corresponding to this data is extracted from the fuzzy data dictionary (22).          Fuzzy-retrieval execution means (20) calculates the degree of membership of the membership function data with respect to the retrieval condition and outputs the result through an output unit (24).
