摘要： Pt catalyst on a substrate provides an air purification particularly for carbon oxide contained in the inhaled air is caused to react with air oxygen on the surface of carbon oxide catalysts and thus removed. But it is desirable for many air filter applications to eliminate, in addition to CO, other harmful gases from the air also. The Pt catalyst used as gaskmask filter material offers, particularly, but little protection additionally against acid gases. Due to an additional impregnation with the oxides of amine-forming heavy metals, the separating powers for acid gases is increased extraordinarily without reducing the capability of the Pt catalyst to oxidize CO catalytically. There even results an intensification of the respective effectiveness.

摘要： A chemical canister for use in a respirator has opposed openings, one for connection to a mouthpiece and the other for connection to the rest of the respirator. The canister contains a carbon dioxide removing and oxygen liberating chemical, and there also is a chemical which, upon being heated, will liberate nitrogen to mix with the oxygen liberated in the canister.

摘要： Provided is a portable air purifier, which includes: a mask part; a first connecting hose having one end connected to the mask part; a second connection hose in which the first connection hose is installed, and at least part of which has an opening for introducing external air; an air purification module that purifies the introduced external air to a predetermined temperature condition and discharges the purified air to the first connecting hose; and a power supply unit configured to supply power to the heater. Since the air purification module for removing poisonous gases or biochemical pollutants through a catalytic reaction of a metal catalyst layer can be semi-permanently used, the conventional inconvenience of carrying an extra canister is removed.

摘要： A low pressure drop device for personal protection against toxic industrial chemicals and chemical warfare agents has a flexible polymer hood impermeable to toxic challenge molecules, a neck seal for sealing the hood about the neck, a half mask for connection to a canister and a low pressure drop canister for chemical protection. The canister contains carbon monoliths of 5- 40 mm diameter, length 1-3 cm, open area 30-60%, surface area ≥700 m2/g optionally activated to >30 wt % weight loss and optionally impregnated with metallic additives and/or triethylene diamine. The monoliths have square channels of size 100-2000 μm and wall thickness 100-2000 μm. It also contains a resiliently flexible closed cell foam with holes slightly smaller than the monoliths so that flow through the canister is through the monoliths.

摘要： The breathing system comprises a canister carrying layered filtering material, including activated carbon granules, a desiccant, a catalyst for the catalyzation of carbon monoxide to carbon dioxide, and electrostatically charged filters between the layers of filtering material. A mouthpiece carrying a noseclip, and inhalation and exhalation check valves and a whistle is disposed within a flexible, substantially completely transparent hear-through hood, both the mouthpiece and hood being disposed in the canister between the filtering material and a cover for the canister. In use, the cover is removed, air inlet apertures are uncovered, and the hood is drawn about an individual's head and substantially sealed about the neck. With the mouthpiece in the individual's mouth, and noseclip closing off the user's nose, inhalation causes air to flow through the filtering material and the inhalation check valve and past the exhalation check valves. When exhaling, the exhalation check valves open to permit exhaled air to flow into the hood. The inhalation valve closes during exhalation to prevent backflow of air through the filtering material. By exhaling into the hood, a slight positive pressure within the hood is established to prevent noxious gases, smoke particles and the like from entering the hood through the neck opening.
摘要翻译：呼吸系统包括承载分层过滤材料的罐，包括活性炭颗粒，干燥剂，用于催化一氧化碳至二氧化碳的催化剂，以及过滤材料层之间的静电电荷过滤器。在柔性的，基本上完全透明的透气罩内设置一个装有防滑圈，吸入和呼气止回阀和口哨的口器，喉罩和罩都设置在过滤材料和罐盖之间的罐内。在使用中，盖被去除，空气入口孔未被覆盖，并且罩被围绕个人的头部拉出并且基本上围绕颈部密封。将嘴巴放在个人的嘴里，并且鼻子关闭用户的鼻子，吸入会使空气流过过滤材料和吸入止回阀，并通过呼气止回阀。呼气时呼气止回阀打开，呼出的空气流入罩内。在呼气期间吸入阀关闭，以防止空气通过过滤材料回流。通过向发动机罩呼气，建立罩内轻微的正压力，以防止有毒气体，烟雾颗粒等通过颈部开口进入发动机罩。

摘要： A breathing bag apparatus and simulator is disclosed that has a circuitous and continuous tube within its bag(s) communicating outside air from an inlet filter and carbon-dioxide-conversion canister to the inhalation fixture of the user's facemask. A permanent carbon-monoxide-conversion cylinder forms part of the path of the tube within the bag(s). The cylinder uses porous ceramic pellets to host a coating of platinum as its catalytic noble metal.

摘要： In CO-air filters the poisonous carbon monoxide contained in the air to be breathed is brought into reaction with atmospheric oxygen on the surface of a CO catalyst and thus removed. The Pt-catalyst used to date as air filter material offers diminished protection when humidity levels in the air are high. By being subjected to an extra impregnation with vanadium compounds the capacity of the palladium catalyst to catalyze the oxidation of CO under high humidity is increased remarkably. Effectiveness is even increased under dry conditions.
