Abstract: A carbon dioxide capture system includes a first heat exchanger configured to exchange heat between an exhaust stream and a lean carbon dioxide effluent stream. The carbon dioxide capture system also includes a first turboexpander including a first compressor driven by a first turbine. The first compressor is coupled in flow communication with the first heat exchanger. The first turbine is coupled in flow communication with the first heat exchanger and configured to expand the lean carbon dioxide effluent stream. The carbon dioxide capture system further includes a carbon dioxide membrane unit coupled in flow communication with the first compressor. The carbon dioxide membrane unit is configured to separate the exhaust stream into the lean carbon dioxide effluent stream and a rich carbon dioxide effluent stream. The carbon dioxide membrane unit is further configured to channel the lean carbon dioxide effluent stream to the first heat exchanger.

Abstract: A temporary platform for assembling elevator equipment in an elevator shaft is arranged substantially in the region of a shaft opening, such that the platform partially sits on a floor surface of the building and partially protrudes into the elevator shaft. The platform includes a bottom frame and bottom plates that lie on or are inserted into the bottom frame. The bottom frame also includes two lateral bottom bars, at least one front and one rear transverse bar that interconnect the two lateral bottom bars, and at least two intermediate bars that are arranged parallel to the two lateral bottom bars. The two intermediate bars are supported substantially by the front and the rear transverse bars.

Abstract: A working device for carrying out fitting or maintenance work in an elevator shaft includes at least one working platform having a standing surface and a railing. The standing surface affords space for at least one person and the railing at least partially encloses the standing surface. The working device also includes at least one additional platform that is attachable to the railing of the working platform, and wherein the additional platform affords an additional standing surface for at least one person. The additional standing surface is arranged above the railing of the working platform.

Abstract: Various embodiments include a method for operating a hazard notification system including a plurality of notification appliances connected to a bus system, each notification appliance having a signal element and an activatable energy consumption simulation unit comprising: receiving a switchover telegram at each notification appliance; attaching the respective energy consumption simulation unit of each notification appliance to the bus system in place of the signal element; measuring an energy consumption resulting in the bus system due to the activation of each energy consumption simulation unit in the course of a load test; comparing the measured energy consumption with predefined comparison values; and generating an alarm signal or a fault message as a function of the result of the comparison.
