Abstract: A component of a rolling load variation which is due to eccentricities of upper and lower backup rolls of the rolling mill is obtained as a first eccentricity compensation signal by removing a rolling load variation component due to a variation of thickness of a material to be rolled from a rolling load variation occurred during the rolling operation. A rolling load variation value due to the roll eccentricity of the backup rolls is obtained from a rolling load variation occurred during rotations of work rolls which are in contact with each other under a load and is memorized as a second roll eccentricity compensation signal. A first signal is obtained by multiplying the first roll eccentricity compensation signal with a coefficient which is larger than 0 and smaller than 1, a second signal is obtained by multiplying the second roll eccentricity compensation signal with another coefficient which is larger than 0 and smaller than 1, and the first and second signals are added to obtain a roll eccentricity compensation signal for the rolling mill.

Abstract: System for transmitting digital-signals over an electrical power distribution circuit by the same modulating at least two different carrier signals. The carrier signals are derived by frequency division from a common master oscillator, and are thus phase-coherent. The system includes a receiver, comprising a respective input circuit for each modulated carrier. A plurality of oscillator signals of different frequencies, derived from a variable frequency oscillator, are used to beat the received carrier signals to respective signals at a common frequency, which signals are summed. This signal is applied to one input of a phase detector, whose other input is connected to receive another common frequency signal from the variable frequency oscillator. The output signal from the phase detector is applied to the variable frequency oscillator to lock its frequency to those of all the carriers and therefore to that of the master oscillator in the transmitter.

Abstract: A system for the control of temperature and humidity in a greenhouse relies on a heat pump and various sensors for the measurement of temperature and relative humidity both inside and outside the greenhouse. Conditions inside and outside the greenhouse are analysed to fall within a particular class and the classes of weather conditions are matched to provide an appropriate control strategy for the greenhouse. The purpose of the invention is to provide for the optimisation of the extraction of useful heat by means of refrigerative de-humidification of the greenhouse and to utilise this heat to minimise the amount of supplementary heat required for the greenhouse, or as a heat source for other heating purposes. It is also the purpose of the invention to provide for the optimisation of the extraction of purified (distilled) water from water supplied to the plants.
