Title: Pc multimedia-based leak detection system for water transmission and distribution pipes
Inventor: HUNAIDI OSAMA
IPC: G01M3/24
Filed: 2001-01-12
Abstract: This invention pertains to the detection of leaks in plastic water distribution pipes by processing the sound or vibration induced in the pipe by water escaping under pressure. Acoustic leak signals are measured at two (or more) contact points with the pipe, e.g., fire hydrants or valves, using vibration sensors or hydrophones.  The signals are digitally recorded using the computer's soundcard. The leak is located using the difference in arrival times of two leak signals as determined from the cross-correlation function traditionally used in leak detection applications or an enhanced impulse response function. The enhanced impulse response function eliminates the need to filter leak signals before processing and hence avoids the uncertainty involved in selecting filter cutoff frequencies for non-experts. Listening to leak sound in plastic pipes is made possible in software by shifting their low-frequency content to an audible higher range. The software implementation of this system can be readily integrated with commercially available RF-based data transmitters and leak sensors - thus providing a complete, flexible, and inexpensive leak detection system.

Title: Combination lock
Inventor: RALEIGH EDWARD A
IPC: E05B67/00
Filed: 2001-03-01
Abstract: A combination lock having a housing, a shackle (14), a dial (13), a pushbutt on (3), and a lock assembly. The lock assembly is made of a group of rotating disks (6, 7, 8, 9) having windows (25) that can be aligned to open the lock.  When the dial (13) is turned according to the combination of the lock, the windows (25) become aligned so that the user can depress the pushbutton (3) to release the shackle (14). The pushbutton (3) travels in a direction that is perpendicular to the axis of rotation of the dial (13). When the shackle (14 ) is locked again, the pushbutton (3) returns to its original position. As the  pushbutton (3) travels back to its original position, portions of the lock assembly are turned so that the combination must be reentered in order to reopen the lock.

Abstract: Methods and compositions are provided for the creation and screening of non- human animal models having chronic inflammation. Immunocompromised host animals are injected with a population of immunocompetent effector cells, depleted of CD25+ T cells. The effector cells are tolerant of the host major  histocompatibility antigens, but reactive to at least one antigen present in  the host animal. The transferred cells are preferably stimulated and localiz ed by administration of an immunostimulant at a local site. The animals are useful for a variety of screening assays and for investigation into disease causes and pathways. A variety of chronic inflammatory diseases may be studi ed with this model, including psoriasis, rheumatoid arthritis, diabetes, inflammatory bowel disease and multiple sclerosis.
