    摘要: A sound masking system for shaping the ambient noise level in a physical environment. The sound masking system comprises a networked and distributed system having a number of master units coupled together and to a control unit. One or more of the master units may include satellite sound masking units which function to reproduce the sound masking signal generated by the master sound masking unit. Each of the master units is addressable over the network by the control unit enabling the control unit to program the contour, spectral band, and gain characteristics of the sound masking output signal. The system may also include a remote control unit which provides the capability to tune and adjust each master sound masking unit in situ without requiring physical access through the ceiling installation. According to another aspect, there is a networked paging system with individually addressable speaker units for announcing a paging signal selected from a number of paging signals.

    摘要: The pyrotechnic smoke kit for generating a smoke screen comprises a mixture of a light-metal powder as the metallic reduction agent; potassium nitrate and, optionally, potassium perchlorate as the main oxidation agent; at least one carbonate as an additional auxiliary oxidation agent; substances splitting off nitrogen as combustion moderators and at least one sublimable and/or evaporable non-toxic smoke-forming substance. A stabilizer from the group of aliphatic and/or aromatic dicarboxylic acids is added to the mixture of the smoke kit to stabilize the smoke kit. Due to this, the formation of gaseous ammonia in the smoke kit can be prevented.

    摘要: A device and method are provided for coupling two storage and/or transport units with a cleaning device. In one cleaning position, either before or after a transfer process, an area is provided between two connecting branches and at least one part of front flaps of two closing valves and the connecting valves which is embodied as a cleaning chamber enclosed on all sides, and which can be sealed with respect to the outside atmosphere and product area. The cleaning space is protected against unintentional opening as a result of at least partial locking of the connecting branches with respect to each other. Cleaning occurs using the cleaning fluid without any danger of contamination be it from transfer product and/or the atmosphere.

    摘要: An apparatus and method for dissuading predatory animals from attacking. The device and method employ depictions of an eye, especially the eye of a predator of the predatory animals, to initiate a startle response in the predatory animal thereby dissuading an attack. The depiction of one or more eyes may be placed on clothing or equipment carried into the aquatic or land based environment of the predator being dissuaded.
