Abstract: The present invention relates to a transmitting device for producing an analog-modulated pulse train and for emitting the same, comprising a pulse generator, with which a pulse train with an individual pulse form can be produced such that the pulse train falls in a predefined frequency band and/or into a predefined frequency mask, a modulation unit connected to the pulse generator and with which a pulse train can be analog-modulated by means of a predefined modulation scheme with respect to the amplitude thereof and/or the position of the individual pulses thereof, and an emitting unit, in particular an antenna, connected to the pulse generator and/or to the modulation unit and suitable for emitting in the predefined frequency band and/or in the frequency range of the predefined frequency mask, with which emitting unit the analog-modulated pulse train can be emitted, in particular beamed.

Abstract: The present invention relates to a transmitting device and to a receiving device.

Abstract: The invention discloses a tool having a work plate which has a mounting area with a mounting opening for mounting the plate on a drive shaft of a drive, preferably an oscillatory drive, the mounting opening being suitably configured for being seated on the drive shaft, wherein centering elements, projecting toward the drive shaft, are provided for centering the tool on the drive shaft.

Abstract: Disclosed is a grinding tool for a grinder comprising a rotary oscillating drive, the output shaft of which is driven so as to oscillate back and forth about its longitudinal axis and is configured for securing the grinding tool thereon. The grinding tool comprises a grinding pad which is made of a resilient material and encompasses at least one grinding surface that runs straight in one direction of extension and parallel to a tangent to the output shaft of the rotary oscillating drive.

Abstract: In a reactor for gasification of solid carbonaceous materials in a fluidized bed under elevated pressure and at high temperatures using a hot gasification agent, a feed device for the gasification agent is installed in the lower part of the reactor chamber and traverses this chamber in the form of a bridge, which has an arch joined to the walls of the reactor chamber, said arch consisting of refractory brick and supporting a section of metal pipe. The latter is shielded from the outside by the arch and by a top-mounted structure of refractory material. On the inside, the metal pipe is also provided with a tubular lining of refractory material. Metal pipe, lining, and arch have openings for passage of the gasification agent. The size and shape of the openings are selected to assure passage of the gasification agent even if the parts undergo changes in length as a result of the effects of temperature.

Abstract: A pressure sensitive copying element in the form of a web having on one side a color forming coating containing a mixture of alkanes of m.w. 500-3500 and dispersed therein 0.1 to 10% by weight of an incompatible material which is a cellulose derivative, hydrocarbon resin, melamine resin, phenolic resin, or styrene resin, and a solution of a color former in a solvent compatible with the material but incompatible with the alkanes. On the other side there may be a color developing coating containing aluminium oxide together with a binder.
