Abstract: A technique for handling messages generated in an industrial control procedure by a first device for being transmitted via a communication network towards a second device is presented, wherein the first device is one of a field device and a field device controller and the second device is the other one of the field device and the field device controller. A method implementation of the technique comprises intercepting a first message generated by the first device, wherein the first message is intercepted before the communication network towards the second device, and wherein the first message has a first message content. The method also comprises storing the first message content and forwarding the first message content on the communication network towards the second device.

Abstract: A logical toy containing movable and/or rotatable elements or element groups, the path of motion or axis of rotation thereof, including sensors staying in an actuating forced connection directly or through a mechanic transmission. One or two circuit switches are suitable for closing and opening the path of electric, magnetic or optical signals, which form, individually or in groups, one or more logical nets serving as signal transmitters. The outputs thereof are connected directly through mechanic connecting elements (4, 5, 9, 11) to an electric counter (2). The sensors, i.e. the signal transmitters (1) containing the sensors, can be connected to an electronic chronometer (6). One or more axes of the toy are hollow or tubular, and the sensors and/or their leads are arranged in the inside of the tubular axes (22) and/or in the hollow of the center-plate elements (18).

Abstract: A process for the underground gasification of coal and carbonaceous materials in makes the customary lengthy preliminary task of establishing an underground interconnection between wells and cavities unnecessary. Instead, according to the invention, the circulation of gasifying agents and product gases is between one or more wells and the boundary of an underground generator (i.e. cavity system) through a reaction zone in the generator.
