摘要： A breathing mask with a half mask and a nape band is to be improved such that secure contact of the mask in the entire nose and mouth region of the mask user is ensured by the nape band. The mask is thus effectively prevented from slipping despite the fact that the band is located in the nape region only. An additional application of a hood is possible without providing additional holding members. To accomplish this task, the band can be applied in the form of a rubber-elastic cuff (5) which has a neck opening (6) and a head opening (7). The mask and cuff are preferably made in one piece of silicone rubber, and the hood can additionally be bonded to the cuff.

摘要： A respirator arrangement including a protective covering, particularly an antismoke hood, and a respiratory connection which is connected to a chemical that absorbs water vapor and CO.sub.2 and releases oxygen, and whose covering or hood material consists of a coated composite material. The coated composite material includes a support fabric of tear-resistant, heat-resistant, and water vapor repellent fibers formed such that the material for the protective covering and the components carrying the respiratory gas stores or releases the smallest possible amount of water vapor, and is resistant to breakage and tearing while having elasticity and suppleness, and can be processed easily. The composite material has a support fabric 1 of glass fibers 2 that has a silane interlayer 5 as adhesion promoter, to which is applied a PVC coating 3 on the side facing the surroundings, and to which is applied a silicone coating 4 on the surface away from the PVC coating 3.
摘要翻译：一种呼吸器装置，包括防护罩，特别是防爆罩，以及与吸收水蒸气和二氧化碳并释放氧气的化学物质连接的呼吸连接，其覆盖物或罩材料由涂覆的复合材料组成。涂覆的复合材料包括抗撕裂，耐热和防水疏水纤维的支撑织物，其形成为使得用于保护覆盖物和携带呼吸气体的部件的材料储存或释放最小量的水蒸气，以及具有弹性和柔软性，耐断裂和撕裂，易加工。复合材料具有玻璃纤维2的支撑织物1，其具有作为粘合促进剂的硅烷中间层5，在面向周围的一侧涂覆有PVC涂层3，并且在表面上施加有机硅涂层4 从PVC涂层3。

摘要： A supply unit for supplying a workplace with electricity and/or gaseous media, with a first, vertically extending supply duct and a second, vertically extending supply duct, wherein the electricity and the media are led to connections on at least one of the supply ducts. From these connections the workplace is supplied and improved such that the ergonomically most favorable arrangement of the supply tubes and electric lines leading to the connections will be possible. This object is accomplished by a section of the side surfaces having an angle of inclination less than 90.degree. in relation to the base such that the ends of the side surfaces pointing away from the base can be connected at a common junction. The connections are arranged exclusively on the outer side surfaces and that the distance between the supply ducts is such that the workplace can be brought into the space between the supply ducts.

摘要： A device for the enrichment of respiratory air with oxygen, includes a supply gas to be enriched which is supplied to at least one concentrator and from there to a product gas line in an adjustable concentration of enrichment. The required concentration of enrichment is adjusted speedily and without loss to the changing amount which is used, and as high a concentration of enrichment as possible at an adjustable and low throughput of the concentrator is achieved by use of a partial flow of the supply gas through a throughput-adjustable bypass line. The bypass line bypasses the product gas line and at least one concentrator.
