Abstract: A communication system for an aircraft, comprising a plurality of radios including at least a first radio that is operable in an encrypted mode for transmitting/receiving encrypted audio signals, and a second radio that is operable in a clear mode for transmitting/receiving unencrypted audio signals; an intercom system that interconnects the plurality of radios, wherein the plurality of radios is connected to the intercom system via a plurality of communication lines; and a security module that is configured to connect or disconnect selected ones of the plurality of communication lines for inhibiting simultaneous transmission of an encrypted audio signal via the first radio and an unencrypted audio signal via the second radio.

Abstract: A tilting apparatus for emptying materials, including bulk material, out of railcars that are open at a top may include a tilting frame that is rotatable about an axis of rotation D and is connected to a platform that can receive at least one railcar, a clamping arm attached to the tilting frame in a rotatable manner, a locking device for preventing relative movement of the tilting frame and the clamping arm, and a bracket that is attached to the clamping arm such that in a tilted position of the tilting apparatus in which the tilting frame has been rotated about the axis of rotation that bracket lies at least partially against an upper edge of at least one of the side walls of the at least one railcar. Further, the hydraulic cylinder may be attached to the bracket.

Abstract: A cooking environment is described for allocating power between multiple cooking systems and providing a calculated amount of energy to a cooking system. The cooking systems can each include a receptacle and a heating/cooling element to heat a product within the receptacle. A controller can receive requests for power from the cooking systems. Based on the requests for power, the controller allocates an amount of time within a time period in which the heating/cooling elements of each cooking system receive electrical energy. The controller can also allocate specific intervals within the time period in which the heating/cooling elements receive electrical energy.

Abstract: Two molded case electrical switches such as circuit breakers, network protectors, disconnect switches and transfer switches, are secured together side-by-side by joining blocks having tongues extending along their sidewalls which engage undercutting grooves undercutting the irregular surfaces of the confronting sidewalls of the switch molded casings with an interference fit. Separate joining blocks for the front and rear sections of the molded casing are driven into place and retained by bolts engaging flanges on the molded casing. The poles are paralleled by external conductors in any desired configuration so that the standard switches can be used without customization.

Abstract: An air-conditioning element includes ducts, through which gaseous or liquid media are passed for cooling or heating. The air-conditioning element is constructed as a solid metal sandwich with a light core of corrugated aluminum and covering layers of smooth aluminum strip. The media guides are formed between the corrugated aluminum and the covering layers, and the media guides are connected with one another by way of the ducts. A method for the production of the air-conditioning element includes the steps of joining together at a joint a stack of two covering layers and a core of corrugated aluminum, which is disposed between the covering layers, by hot rolling, adhesives, lacquers or other adhesion promoters that have been previously brought into the regions of the joint; and after the stack has cooled, milling a duct in a perpendicular direction to the course of the corrugations, and then closing off the open sections of the duct by a metal strip.
