Abstract: A plant grown from seeds derived from a new interhybrid of three plants of the Momordica genus has been cultivated. The new plant hybrid has a faster growth rate than the parent species. Parts of the new interhybrid plant which, when ingested by an individual, have blood glucose and/or insulin regulating properties. Foods and/or beverages containing parts or extracts of the new interhybrid plant and which to promote weight control or loss and/or blood glucose regulation are also disclosed.

Abstract: A code signal representing a sequence of code symbols carrying digital information is generated with the frequency components of the code signal being essentially confined to a preselected signalling band lying within the bandwidth of an audio signal within which the code signal is to be embedded. The audio signal is continuously frequency analyzed over a frequency band encompassing the signalling band and the code signal is dynamically filtered as a function of the analysis thereby to provide a modified code signal with frequency components which are, at each time instant, essentially a preselected small proportion of the levels of the corresponding audio signal frequency components. Accordingly, the modified code signal can be combined with the audio signal to obtain a composite audio signal which is not readily distinguishable from the original audio signal by listening.

Abstract: An automatic control varies the ground speed of a combine due to changing field conditions, based on engine speed and combine feeder conveyor load variables.

Abstract: The threshing cylinder and feeder conveyor of a combine with electrohydraulic elements are controlled by a digital computer. The computer generates a proportional voltage which is input to a linear amplifier. The amplifier provides control of the spool of an electrohydraulic servovalve. The servovalve controls the speed and direction of the threshing cylinder and feeder conveyor hydraulic motor drive. Tachometer sensors provide feedback measurement of the actual speed of the hydraulic motor output shaft. Analog-to-digital converters (A/D's) interface the computer with the sensors. Control algorithms employ velocity feedback and compensation for pressure rises due to increases in the torque on the cylinder caused by the material to be threshed entering the threshing cylinder-concave region. Easy reversal of the direction of the threshing cylinder and feeder conveyor, eliminating some of the problems associated with plugging, is available with this type of speed control equipment.
