Appl. No.:

10/897446

International Classification:

F16K 1/00

US Classification:

13762528, 251210, 251331

Abstract:

A low-flow diaphragm valve is disclosed having a flexible diaphragm that cooperates with a portion of the valve body to open and close the valve. The diaphragm may have a portion for seating in a passage between the inlet and outlet of the valve and may have one or more ribs for seating against other portions of the body located around the passage. While the valve body may include openings or interruptions to permit fluid and small particulate matter to flow through the valve, the ribs and openings block or restrict particulate matter of relatively large size from flowing to the passage between the diaphragm and the valve body. With this structure, the valve will function even when particulate matter is trapped between one or more of the diaphragm portion that sits in the passage and ribs, on the one hand, and the body on the other hand.

Appl. No.:

11/365413

Inventors:

Gary Clayton - Vail AZ, US
Victor Olivas - Tucson AZ, US

International Classification:

F16K 15/00

US Classification:

137512000

Abstract:

A backflow prevention device includes a main body holding a removable cartridge. The removable cartridge houses two independently acting check valves and, optionally, a relief valve. A first portion of the cartridge may be retracted into a second portion of the cartridge, thereby reducing the overall length of the cartridge and facilitating the removal of the cartridge from the main body without the need to remove the backflow prevention device from a water supply system. The relief valve is contained in a removable cartridge. Each check valve may have a self cleaning plunger bore comprising at least one spiral groove.

G11B 1568

US Classification:

36447806

Abstract:

An automated storage system transports data cartridges between a storage device and a plurality of storage cells via a picker assembly. The storage cells are formed of one or more removable magazines. The picker assembly accurately locates each data cartridge within a storage cell by first establishing a zero position reference and locating a home position relatively therefrom. The home position is a predetermined point on each magazine. An infrared detector and infrared sensor are situated on the picker assembly for precisely locating the home position. Each cartridge is known to be located within a predetermined tachometer count range from the home position. The detector/sensor is used to precisely locate each cartridge. The precise tachometer position is stored and the cartridge is returned to the known location. As a result, tolerance accumulation effects are eliminated in the system.
