Patent number: 11391772Abstract: A signal transmission system with at least one signal encoder, a line, and a control and evaluation unit, wherein the signal encoder has an electronic unit and a power source, wherein the signal encoder feeds an imprinted current in the range between a preset first value and a preset second value into the line, in particular between 4 and 20 mA. The control and evaluation unit has a load and a microprocessor, and captures and evaluates a voltage that decreases via the load or a current that flows through the load. Additional information regarding the status of the components, can thus be captured and forwarded in a simple way, in that the load in the control and evaluation unit is connected in series to at least one electrical component at which a direct current appears when a current flows through the electrical component.Type: GrantFiled: July 31, 2020Date of Patent: July 19, 2022Assignee: GESELLSCHAFT FÜR GERÄTEBAU MBHInventors: Hans-Jörg Hübner, Frank Böttger, Erik Buck

Patent number: 7498575Abstract: An optical analysis device having a gastight housing, a radiation-permeable housing element, at least a first radiation source and associated first reflector and a second radiation source and associated second reflector, at least first and second detectors, and an external reflector. The radiation sources and the detectors are located within the housing, an absorption space being formed between the external reflector and the radiation-permeable housing element. A measurement beam emitted by the first radiation source and the first reflector, after reflection on the external reflector, re-enters the housing. A reference beam is emitted by the second radiation source and the second reflector. The measurement beam, after crossing the absorption space, is guided from the measurement beam reflector directly onto the first detector and the second detector and the reference beam from the second radiation source is directly incident on the first detector and the second detector.Type: GrantFiled: June 23, 2006Date of Patent: March 3, 2009Assignee: GFG Gesellschaft für Gerätebau mbHInventors: Joerg Huebner, Rainer Krage

Patent number: 5018520Abstract: Lithium batteries used for an aeration or breathing apparatus, such as gas masks or protective suits, are enclosed in a housing, and the enclosure has a predetermined breaking point to release gases which may accumulate in the interior. The housing surrounding the lithium batteries has a closure, which opens when the compressed gases are released, to allow the gases to be safely discharged to the outside.Type: GrantFiled: March 21, 1989Date of Patent: May 28, 1991Assignee: Gesellschaft fur Geratebau mbHInventors: Hans-Jorg Hubner, Heribert Rische
