Title: Composite ion-exchange material, preparation and use thereof
Inventor: MAGLIO ALFONSE
IPC: B01J47/00
Filed: 1993-07-14
Granted: 2004-06-08
Abstract: Inorganic hydrated metal oxide and metal silicate gels are supported on the surface of particles of porous material by precipitation therein without significant deposit within pores of the suppor t material and without encapsulating the particles of porous material. Especially preferred hydrated oxides and silicate gels are those of titanium. Preferred porous particles are composed of carbon. These novel composite materials are prepared by spraying an aqueo us basic material to the porous particles and then spraying a concentrated aqueous acidic solution of a source of suitable metallic ions so as to rapidly form a gelatinous precipitate on the surface of the porous particles which remain porous.

Granted: 2000-12-26
Abstract: Metallic powders are extruded from a spinning nozzle to form metallic fibers each having a diameter of 1.0µm - 100µm. The resultant metallic fibers are formed into a sheet having a porous structure, such as a nonwoven sheet, or the like. Thereafter, the sheet is sintered. An active substance is applied to pores of the resultant porous metallic sheet to make it usable as an electrode substrate of a battery. The metallic fibers are three-dimensionally intertwined with each other by using a fluid at high pressure and high speed. The surfaces of the intertwined metallic fibers are fused together under pressure at a temperature lower than the melting point of the metal in order to directly connect intersections of the fibers to form the porous metallic sheet.

Title: Reduced misting oven cleaner
Inventor: LENTSCH STEVEN E
IPC: C11D3/43
Filed: 1994-08-04
Granted: 2004-12-21
Abstract: Spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray head have been known to cause respiratory distress in the form of a chocking mist. The chocking mist associated with aerosol us e can be reduced or eliminated by formulating surface cleaning compositions that can be dispensed through a spray head resulting in an aerosol or mist droplet having a mean particle size greater than about 200 .mu.m. We have found that typical spray-on cleaners have a mean particle size less than about 175 ~,m and, depending on the concentration and degree of irritation of strong base or strong acid components, can cause severe respiratory distress. Preferred thickeners have been found for use in the non-chocking aerosol or mist compositions.</S DOAB>

Title: Transmission rate judging unit
Inventor: NARA YOSHIKAZU
IPC: H04L7/00
Filed: 1997-06-27
Granted: 2000-12-05
Abstract: A method and system is disclosed for determining an actual transmission rate of an encoded communication which has been transmitted at one of a plurality of transmission rates. An encoded communication is decoded at the plurality of transmission rates to generate decoded signals and decoding parameters which indicate the reliability of the decoded signals. One or more candidate transmission rates are identified based upon said decoding reliability parameters. If there is only one candidate transmission rate, the actual transmission rate is determined to be that candidate transmission rate. If there is more than one candidate transmission rate, the decoded signals are reencoded at the candidate transmission rates at which they were decoded. The bits of the communication are then compared with the bits of the reencoded signals for each candidate transmission rate to determine the actual transmission rate. A method and system is further disclosed for determining threshold values for comparison with the decoding reliability parameters in identifying the candidate transmission rates. A method and system is further disclosed which determines those threshold values on the basis of detected reception conditions, including the relative strength of multipath component signals and the total received power in the communication.

Title: Esophageal dilation balloon catheter containing flexible nitinol wire
Inventor: KELLY PATRICK A
IPC: A61F2/958
Filed: 1996-02-05
Granted: 2006-09-19
Abstract: A catheter such as a balloon dilation catheter (10) useful in endoscopic or other surgical procedures can be rendered kink-resistant by the inclusion of a flexible nitinol wire (24). The nitinol wire (24) has a transition temperature well below the temperature of the body, so that it remains superelastic during use of the catheter (10), and permits the catheter (10) to remain essentially unkinked through acute bends and toms which would unacceptably kink comparable catheters having wires of stainless steel or other materials. The potential for patient injury from the catheter is thereby reduced. The catheter (10) includes a tubular polyurethane catheter shaft (12) having a fluid flow lumen (14) defined therein, and an expandable but nondistending PET balloon (18) connected to the distal end (16) of the shaft (12) in fluid communication with the lumen (14). The catheter (10) also includes a flexible catheter tip (22) on the balloon (18) opposite the catheter shaft (12). The nitinol wire (24) is positioned within at least the catheter balloon (18) and the catheter tip (22), and preferably extends the entire length of the catheter shaft (12) through the shaft flow lumen (14). The longitudinal positions of the nitinol wire (24) and the balloon (18) are fixed relative to one antoher by a radiopaque insert (32) in the distal end (16) of the catheter shaft (12). The nitinol wire (24) preferably includes a tapered portion (28) extending from a location (30) within the balloon (18) to the distal end (26) of the nitinol wire (24) in the flexible catheter tip (22). A conventional female luer hub (38) can be connected to the catheter shaft (12) opposite the balloon (18) and the distal end (16) of the shaft (12).

Granted: 2008-08-12
Abstract: Mold removal from plastic bottles such as polyester and polycarbonate bottles is significantly enhanced by adding to a typical caustic soaking solution an effective amount of a complex polyphosphate such as sodium tripolyphosphate and a surfactant. The combination of the phosphate and the surfactant significantly enhances mold removal. Mold removal can be further enhanced by combining with the phosphate and surfactant either a phosphonate and/or a chelating agent such as sodium glucoheptonate. This combination signficantly improves mold removal, but does not increase stress cracking of the plastic bottle.
