Abstract: Combined amplitude and frequency-shift-keying (AM-FSK) modulation of a carrier wave by the same baseband data signal achieves significant suppression of one of the sidebands to ease the design requirements of filters generally used in the transmission of FSK signals. Significant suppression effect is observed when the ratio of minimum to maximum amplitude of the envelope of the smplitude modulated carrier wave is restrained to be approximately between 0.6 and 0.9.

Abstract: A data transmission path comprises a first and a second station, a first data transmission channel operative for synchronously transmitting data from the first to the second station in synchronism with a predetermined clocking schedule and at a respective first maximum data transmission rate, and a second data transmission channel for asynchronously transmitting data from the second to the first station at a respective second maximum data transmission rate, the first maximum data transmission rate being equal to a multiple p of the second maximum data transmission rate. A test waveform is applied to the first station for transmission to the second station along the first data transmission channel, the test waveform presenting a data transmission rate at least approximately equal to said first maximum data transmission rate. The test waveform, as received at the second station, is applied to a selector circuit whose output waveform is applied to the transmitting input of the second station for transmission back to the first station along the second channel. The selector circuit transmits to its output only every p-th one of the waveform elements applied to its input, relying on clock signals which the second station produces one per waveform element of the synchronously transmitted test waveform. The shortest waveform-element duration of the waveform produced at the output of the selector circuit at least approximately corresponds to said second maximum data transmission rate.

Abstract: Discs (4 und 5) are mounted on a shaft (3) and cables (6) extend between the peripheries of adjacent discs (4 and 5) for use as ground engaging means. 
     The shaft (3) and the discs (4 and 5) are rotated in the same direction as the wheels (2) of the cultivator, but a different peripheral speed. As a result of the difference in peripheral speeds of the wheels (2) and the discs (4 and 5), the cables (6) are caused to cultivate the ground. However, as the discs (4 and 5) are rotated in the same direction as the wheels (2), any weeds or other material dislodged by the movement of the cables (6) will be carried rearwardly by the cables (6) and deposited behind the cables (6), thus avoiding a build-up of unwanted material in front of the cultivator.

Abstract: A process and apparatus for continuously sterilizing a cocoa paste, wherein the cocoa paste is subjected to a thin layer continuous treatment of deacidification, dehumidification and degasification in a thin layer device prior to delivery to a sterilization reactor. Following sterilization and cooling, the treated cocoa paste is conveyed to a second thin layer device for residual deacidification, dehumidification and degasification. While in the sterilization reactor, the cocoa paste is heated by mechanical mixing, generating a temperature in the range of 100 DEG  C. to about 150 DEG C. which is necessary for degermination. The degermination temperature is held at its average value by an external heat exchanger. A cooling device is connected to the sterilization reactor at the outlet side thereof for cooling the treated cocoa paste to below 100 DEG  C. before being conveyed to the second thin layer device for further treatment.
