The deodorizing filter is formed so as to incorporate a deodorizing element in a housing and have a gas inlet at one side of the deodorizing element, an outlet at the other side of the deodorizing element, and a space existing at that side of the deodorizing element which faces the ostomy bag.

Abstract: A method for high concentration carburizing and quenching of steel is provided which is carried out by a treatment process including the steps of carbonitriding the steel at temperatures of from about 800 to about 880° C., and subsequently quenching the steel at a temperature higher than the carbonitriding temperature. In the carbonitriding step, the steel is treated with carbon concentrations in a carburizing atmosphere taken as about 0.7 to about 1.2% and with 3 to 8% of ammonia gas (NH3) being added, for example. This dissolves network-like carbide in austenite and, when the austenite is transformed into martensite by quenching, distributes the dissolved carbide in the form of granules approximately uniformly in the martensite.

The present invention also relates to a prepolymer for forming the polyurea foam and the present invention especially relates to the use of a carborane disilanol fire retardant polyol. The present invention also relates to a method for forming the polyurea foam and the prepolymer.

Abstract: Thermosetting, bottom-applied polymeric anti-reflective coatings exhibiting high optical density, rapid plasma etch rates, high solubility in preferred coating solvents, excellent feature coverage, and improved stability in solution are disclosed. The principal component of these new anti-reflective coatings is a polyester resin produced by the reaction of one or more difunctional aliphatic carboxylic acids with a stoichiometric excess of a di- and/or a trifunctional aliphatic primary alcohol, wherein at least one of the dicarboxylic acids may contain a reactive methylene (--CH.sub.2 --) group. The resulting polyester resin reaction product is further modified by attaching light-absorbing groups to some or all of the reactive methylene groups (if present) and/or hydroxy groups present on the resin. The dye-attached polyester resin is combined with an aminoplast crosslinking agent and acid catalyst in a suitable solvent system to form the final anti-reflective coating.

Abstract: A high optical density, i.e., .gtoreq.3.0, at 1 micron or less film thickness, black matrix is disclosed having improved stability and shelf life as a consequence of admixing Pigment Black 7 and organic dye or dye mixtures on a polyimide polymer vehicle.

Abstract: There is provided a high frequency pulse generator having inlet ports for receiving a fluid mass flow rate and output ports that produce a pulse flow rate therefrom by being opened and closed by a chopper wheel. The duty cycle of the generator is controlled by the ratio of the aperture sections of the chopper wheel to the closure sections of the wheel. The housing of the pulse generator may be divided into separate sealed chambers for receiving independent fluid mass flow rates in each chamber and providing independent variable phased pulsed output flow rates.

Abstract: Carbon dioxide; from a boiler flue gas stream is separated, recycled and utilized for gasification of coal or biomass to increase fuel utilization and to decrease the carbon dioxide emissions into the atmosphere.

Abstract: The invention is an air flow control valve which is capable of maintaining a constant flow at the outlet despite changes in the inlet or outlet pressure. The device consists of a shell assembly with an inlet chamber and outlet chamber separated by a separation plate. The chambers are connected by an orifice. Also located within the inlet chamber is a port controller assembly. The port controller assembly consists of a differential pressure plate and port cap affixed thereon. The cap is able to slide in and out of the orifice separating the inlet and outlet chambers. When the pressure differential is sufficient, the differential pressure plate rises or falls to maintain a constant air flow. Movement of the port controller assembly does not require the use of seals, diaphragms, tight tolerances, bushings, bearings, hinges, guides, or lubricants.

Abstract: The invention is a mechanism for the streamwise deployment of an aircraft trailing or leading edge flap. The mechanism connects the spar and flap. There are a pair of swivel links which pivotally connect the spar to the flap. There are also a pair of slaving mechanisms which rotationally connect the spar to the flap by spherical bearings. A linear flap actuator initiates the combined pivotal and rotational action from the spar which translates into a single downward and rearward motion of the flap.
