Abstract: A signal simulation device for testing and developing radio receivers adapted to orientate antenna beams to different radio transmitters and to simultaneously suppress interference signals, comprises an antenna array, a signal generator generating reproducible digital signals in the complex baseband, and a digital matrix processor combined and synchronized with the signal generator. The processor has input signals generated by the signal generator and has output signals that form received signals of the antenna array. The input signals of the matrix processor are phase shifted according to a direction of incidence and to relative positions of the elements within the antenna array of the radio receiver, and are combined and supplied to outputs of the matrix processor. Amplitude and phase shift are simulated by weighting of the input signals from the signal generator, the weighting coefficients being calculated on a control computer and input into the matrix processor via an interface.

Abstract: For regulating the pressure in a pressure chamber, in particular in a pneumatic brake apparatus for a web-type recording medium, an actual pressure is set in the pressure chamber dependent on an actual angle of rotation of a rotary valve. The actual angle of rotation of the rotary valve and the actual pressure in the pressure chamber are acquired. A target pressure and a target angle of rotation allocated to this target pressure are predetermined, and a pressure deviation between the actual pressure and the target pressure are determined, as is a deviation of the angle of rotation between the actual angle of rotation and the target angle of rotation. An adjusting unit sets the angle of rotation at the rotary valve, first dependent on the deviation of the angle of rotation and then dependent on the pressure deviation. Furthermore, a sensor for acquiring the angle of rotation is specified.

Abstract: A printer for printing endless paper webs on both sides has two printing stations with a web turnover station therebetween. The paper web is fed in parallel side-by-side to the two printing stations which are on the same rollers. The drive of the web through the printer is by a positive drive, using pins to engage holes in the paper web, for example, into the first printing station. The drive of the paper web thereafter is by friction drive to permit slippage in the drive to compensate for variations in paper length during heating, etc. The slippage is controlled by brakes or other drag inducing devices acting on one or both of the two portions of the paper web.

The preheating saddle (15) is designed as a low temperature saddle with the largest possible constructional length, so that the temperature difference between recording substrate (17) end saddle surface (24) is as small as possible. The preheating saddle has, in the recording substrate running direction, a plurality of heating zones (21, 23). A control device controls the heating zones (21, 23) in such a manner that, along the preheating saddle (15), an approximately constent thermal energy flow occurs on the saddle surface (24) to the recording substrate (17).
