Abstract: Abstract of the Disclosure A harvester in the form of a self-propelled combine (11) has a crop header (24) and conveying means (31, 32) feeding crop material to a threshing rotor (34). The speed of rotation of the rotor (34) is adjustable by changing the speed of a variable speed belt drive (50) in the drive train from an engine (16) to the threshing rotor (34).  The variable speed belt drive (50) is of a type whose speed ratio cannot be changed unless it is running.  A special rotor clutch (71) is interposed between the variable speed belt drive (50) and the threshing rotor (34) to permit the variable speed drive to be disconnected from the threshing rotor.  Thus, when the rotor (34) stops rotating because of excess crop material, the rotor clutch (71) may be operated to break the power train between the variable speed belt drive (501 and the threshing rotor (34) and the variable speed belt drive (50) may be run and adjusted to a lower output speed.  Upon reengagement of the rotor clutch (71), higher torque can be delivered to the threshing rotor (34), thus, greatly increasing the probability of turning the rotor (34) to overcome the crop material jam.

Abstract: DISENGAGEABLE SINGLE LEVER CONTROL ASSEMBLY     ABSTRACT OF THE DISCLOSURE                  A control lever assembly, particularly for controlling marine propulsion systems, having first and second signal outputs con-trollable simultaneously by a single lever.  The lever is journalled for rotation about a lever axis relative to a body, and can be shifted axially between engaged and disengaged positions.  An interrupter driver has driving engagement structure and responds to lever rotation and cooperates with the first signal output.  An interrupter driven structure has driven engagement structure which is engageable with the driving engagement structure when the lever is in the engaged position, and is disengageable when the lever is in neutral and is shifted axially.  When engaged, the second signal output is responsive to primary rotation of lever.  Selector structure permits the axial movement only when the lever is in neutral, and simultaneously permits rotation of the lever to control the first signal output with no corresponding change in the second signal output.  The assembly also permits easy conversion to a twin engine control in which equal rotation of the levers produces essentially identical output signals.

Abstract: MEDICAL INSTRUMENT FOR NONINVASIVE MEASUREMENT          OF CARDIOVASCULAR CHARACTERISTICS              ABSTRACT OF THE DISCLOSURE         A medical instrument includes a noninvasive pulse transducer which senses heart beats of a human subject.  Based upon pulse signals from the transducer, the instrument provides visual stimulae which allow the human subject to voluntarily synchronize the subject's respiration cycles with the subject's heart beats.  At the same time, the instrument determines and stores the instantaneous beat-to-beat heart rate for each beat of the respiratory cycles.  After a predetermined number of synchronized respiratory cycles have been completed, the instrument performs both classical statistical and rhythmometric analyses utilizing the stored instantaneous heart rates,  The instrument determines from these analyses mean and standard error values for each beat of the respiratory cycle; an analysis of variance of the mean value; a rhythm qualified mean heart rate value; an amplitude value; a timing value (which indicates the location of the peak of the cosine curve best fitting the heart rate data within the respiratory cycle), and a percent rhythm value (which indicates the quality of the fit with the cosine curve to the stored instantaneous heart rates).  The amplitude value provides an indication of the physiological (as opposed to chronological) cardiovascular age of the human subject, since it indicates the compliance of the heart tissue. The effect of cardiotoxins, cardiac drugs, other substances, as well as altered physiologic states upon a subject's heart tissue compliance also can be monitored using the amplitude, mean and peak timing values produced by the instrument. The instrument provides a displayed and/or printed output so that the subject or his or her physician has a simple yet accurate indication of heart condition which may be evaluated periodically and followed over time.

Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to a method for recharging a chargeable battery for a motor vehicle, a machine, a motor boat or the like.  As the charging voltage there is used the output voltage from a charging generator which is connected to the battery, the output voltage being varied by controlling the field of the generator.  The charging takes place by means of repeated charging cycles each of which consists of a charging period and a test period when the battery is loaded and the charging from the generator to the battery is disconnected.  The value of the charging voltage during a charging period is determined on the basis of the test result during the immediately preceding test period.  According to the invention the battery voltage is compared to a pre-determined voltage during each test period. If the comparison shows that the battery voltage is less than the pre-determined voltage or drops below this voltage during the test period, the charging of the battery during the following charging period takes place at a charging voltage which is sufficiently high that, by controlling the output voltage of the generator, there is rapid charging of the battery.  If the comparison shows that the battery voltage is higher than the pre-determined voltage the charging during the following charging period takes place at a charging voltage which provides a compensating charging of the battery.  During the later part of the charging period, just before the test period, the charging always takes place at a charging voltage corresponding to the compensating charge.

Abstract: IMPROVED ATOMIZATION APPARATUS AND METHOD FOR LIQUID FUEL BURNERS AND LIQUID ATOMIZERS                   ABSTRACT An improved apparatus and method for burning liquid fuel or atomizing liquid are disclosed for use in fuel burners or atomizers of the type which comprise a hollow atomizer bulb having a smooth, preferably convex exterior surface which tapers toward a small aperture through which high pressure air or other gas is forced to atomize liquid as it flows in a thin film over the exterior surface of the bulb.  Such atomizer bulbs are located within an atomizing chamber through which a flow of air or other gas is directed toward a discharge opening aligned with the aperture of the atomizer bulb.  To protect the thin film of liquid flowing over the exterior surface of the bulb, the bulb is enclosed within a shield which also permits the atomizer bulb to be located closer to the discharge opening so that the flame front is positioned in the flame tube rather than in the discharge opening.
