Title: Firefighter protective turnout pant
Inventor: BARBEAU CLAUDE
IPC: A62B17/00
Filed: 1996-08-08
Granted: 1999-04-13
Abstract: The firefighter's turnout pants according to the invention are designed so that each pant leg comprises a front panel and a back panel above the knee region, the panels being joined by an outseam and an inseam, and cylindrical panels below the knee region, the cylindrical panels being each joined by only an outseam and connected via a circumferential seam at the knee to the two-panels above the knee. The absence of an inseam below the knee of the firefighter's pants eliminates a chronic problem of abrasion of the threads used in that portion of the inseam and subsequent failure of the inseam. The absence below the knee of an inseam with the potential for failure reduces the maintenance and repair of the firefighter pants, reduces the risk of burn injury resulting from a breach in the protective envelope of the firefighter's pants, and reduces the incidence of reflective trim becoming coincidentally detached from the pants.

Title: Fluid treatment system and process
Inventor: MAARSCHALKERWEERD JAN M
IPC: B08B9/02
Filed: 1994-03-04
Granted: 2000-01-18
Abstract: A fluid treatment system includes one or more radiation sources arranged in an irradiation zone within a treatment zone through which fluid to be treated passes and is irradiated. The irradiation zone has a closed cross-section to maintain the fluid within a predefined maximum distance from the radiation source. Preferably, the irradiation zone comprises a reduced cross-sectional area perpendicular to the direction of fluid flaw and thus the fluid flow velocity is increased through the irradiation zone. This allows the fluid to enter the treatment zone at relatively law speed, traverse the irradiation zone at high speed and exit the treatment zone again at relatively low speed to minimize the loss of hydraulic head throughout the system. Fluid entering the treatment zone passes through an inlet transition region wherein the cross-sectional area is reduced prior to entering the irradiation zone and fluid exiting the irradiation zone passes through an outlet transition region wherein the cross-sectional area is increased. Each transition region is designed to reduce hydraulic head losses as the fluid flow velocity is increased and decreased. In the irradiation zone, radiation sources are mounted on radiation modules which are arranged to provide improved accessibility for maintenance. The radiation modules may also be provided with cleaning assemblies which are operable to remove materials fouling the radiation sources in situ while the radiation sources are in the irradiation zone.

Title: A geographical information search system
Inventor: WHITAKER NORMAN ASHTON JR
IPC: G06F17/30
Filed: 1998-07-21
Granted: 2002-01-22
Abstract: A network-based search system is disclosed in which queries and information records are qualified by temporal and geographical references, such as those provided by a map-based directory system. Briefly, queries are submitted using text strings together with time tags and location tags. Time tags and location tags refer to the date/time the query was last submitted for a search and the geographical area of interest (defined by ranges of latitude and longitude coordinates), respectively. The information records being searched preferably contain similar time and location tags. However, time and location tags associated with information records refer to the date/time the record was last modified and the origin of the record, respectively. A mechanism is also provided for determining location tags for records that do not include location tags. In all, a comparison between the time and location tags associated with a query and the time and location tags associated with the information records permits geographically irrelevant records to be suppressed and allows the user to automatically receive only information that has been modified since the user last requested it. Thus, search results are automatically pre-filtered prior to being transmitted to the user who originated the query, thereby conserving network resources and reducing the amount of context-based filtering required of the user.

Title: Process for accelerating reaction of ozone with am catalyst
Inventor: MIURA KAZUHIRO
IPC: C02F103/02
Filed: 1998-11-24
Granted: 2002-09-24
Abstract: In treatment of water by injection of ozone into the water for removal of harmful matters, odor matters, and color matters therein, either or both of a nonyl phenol and a cresol are added to the water to be treated. The nonyl phenol is added together with a lower alcohol or acetone to the water to be treated. The cresol is added together with a lower alcohol or acetone to the water to be treated. A p-nonyl phenol is added as the nonyl phenol for treatment. As the cresol for addition, a p-cresol is added. As the nonyl phenol for addition, such a nonyl phenol that two molecular weights of 220 and 107 are detected when measured by either or both of gas chromatography and mass spectrometry is used. By the above treatment, the decomposition reaction of ozone can be accelerated, and thereby it becomes possible to accelerate the oxidative decomposition reaction of organic matters, the amount of ozone required for the decomposition of harmful matters can be reduced with the decomposition time, The decomposition rate of organic matters can be accelerated by addition of a nonyl phenol or a cresol. Accordingly, when the process for accelerating the reaction of ozone is applied in water treatment, the treatment rate of water can be enhanced. The treatment volume per time of water can be enhanced, whereby the site area for water treatment facilities can be reduced even in the event that the capacity of a reaction tank is reduced.
