Abstract: A container for the gastight sealing of a respirator. The container has two container shells (1, 2) abutting on front surfaces with a circumferential sealing element. The container second container shell (2) is provided with a handle (3) mounted at two opposite points of rotation (6). The handle (3) has a lever arm (5), which engages in the first container shell (1) in the closed position of the container. In the closed position of the container, the handle (3) preferably engages in an additional bracket (4) that is detachably connected to the first container shell (1).

Abstract: A respirator to be worn in front of the chest with regeneration of the breathing air, containing a regenerating cartridge with a plurality of chemical layers, a breathing bag, a connection piece on the side of the breathing bag located opposite the regenerating cartridge, a breathing hose pointing from the connection piece to the user, and an oxygen-releasing starting device at the regenerating cartridge. The supply of oxygen into the breathing bag and the wear properties are improved by the breathing bag being designed as a bag lying flat on the regenerating cartridge and having a ring-shaped hose part, which can be laid around the neck of the user. This provides a neck opening formed within the breathing bag. An opening is provided in the chemical layer located opposite the breathing bag. A starting device is accommodated in this opening such that it is in flow connection with a collector chamber opening into the breathing bag.

Abstract: A container and locking device for gas tightly locking a container for gas masks and breathing equipment containing moisture-sensitive filter mass, including a first container shell and a second container shell, each container shell having outwardly projecting circumferential edges at front surfaces, the first container shell and the second container shell abutting at the front surfaces. A strap surrounding the projecting circumferential edges to clamp the circumferential edges. A sealing member connecting the first container shell and the second container shell, the sealing member being inserted into grooves located at the front surfaces of the first container shell and the second container shell.

Abstract: A gas mask and breathing equipment air cleaning cartridge (1) with a carbon dioxide-binding chemical packing (4) and an insert (3). The insert has legs (6) arranged in a radiate pattern perpendicularly to the direction of flow. The legs (6) have a flexibility that compensates for differences in the filling ratios of the strands (5) of chemical and have an identical bent zigzag-shaped designs to provide good heat distribution in the circumferential direction and good resistance to vibrations and shocks.

Abstract: A moisture indicator for indicating the state of moisture loading of an oxygen-releasing chemical in a respiratory protection device which contains the peroxide of an alkali metal as the substance is to be improved such that it will indicate an irreversible and clearly recognizable color change and will respond to the intrusion of even small amounts of moisture. To accomplish this task, the substance contains as the reactive substance an additive in the form of an alkali metal ozonide that engages in a color reaction with moisture present in the air.

Abstract: A respirator with regeneration of the respired air by several chemical fillings, which emit oxygen and bind carbon dioxide and are disposed in parallel in the respiratory passage between a mouthpiece and a breather bag is to be improved, so that a uniform utilization of the chemicals in the fillings is achieved. The different resistances of the respiratory paths of the fillings are to be evened up so that the pollutant load on and the consumption of the fillings can be divided up evenly over the existing fillings during the whole of the period of use. For this purpose, provisions are made so that each filling is connected to its own breather bag for accommodating the exhaled air flowing through it.

Abstract: A closed-cycle breathing equipment and gas mask for operation under pressure with a pressurized air source for respiratory air and with an air bag being under prestress during the inspiration phase includes an arrangement where the prestress is decreased by a control element recognizing the expiratory phase and so as to support respiration during the expiration phase. A pneumatic control valve is used which can switch connections between the inspiration and the expiration phase and which is directly controlled by the difference between the exhalation pressure and the pressure in the air bag. The control valve connects the pressurized air source with the air bag during the inspiration phase and during the expiration phase it interrupts the connection due to the occurring dynamic pressure of the pressurized air from the pressurized air source and thus actuates a pneumatic adjusting element so that the mechanical prestress at the air bag is reduced.

Abstract: A breathing apparatus removably mounted in a housing has a device for processing the breathing gas. This device includes a container and a charge for processing the breathing air which is disposed in the container. The container has air pass-through openings at least one of which is closable with a stopper. The breathing apparatus provides an indication of possible entry of water vapor and this indication is limited to only the water-vapor sensitive parts of the breathing apparatus. For this purpose, a charge is provided in the stopper having a moisture-sensitive indicator which is visible through a viewing window from outside the housing and this charge is in gas contact with the charge of the device for processing the breathing gas.
