Abstract: ABSTRACT OF THE DISCLOSURE       A dynamoelectric machine having a multiple of three poles and a corresponding multiple of three brushes is disclosed.  Each of the poles are wound poles, two of each group of three poles being excited with a constant excitation during normal operation, the third of each group of poles being a control pole, excited to as to produce a flux that both varies in magnitude and reverses in polarity.  With an input voltage connected to first and second brushes of each group of three, an output voltage may be derived from first and third brushes in a magnitude determined by the polarity and intensity of the field of the control pole.  The machine is also adapted to provide mechanical output power from its rotating shaft, and also to accept input power from its rotating shaft.  The output voltage obtainable may be varied between zero and the value of the input voltage, and also increased above the input voltage, and decreased below zero, reversing polarity.  Means are also disclosed for providing regenerative breaking of a motor driven by the output voltage of the machine and returning power to a battery power supply without increasing shaft speed of the machine, by augmenting the flux of a pole to increase the input voltage while main-taining the output voltage constant.

Abstract: METHOD FOR PREPARING TISSUE HEART VALVE            ABSTRACT         A method for preparing an aortic heart valve for implanta-tion wherein the area of the septal shelf of the right coronary cusp extending into the valve orifice is substan-tially reduced.  The excised valve is prepared for fixa-tion by pressurizing the valve to close the valve cusps, and thereafter inverting the aortic vestibule tissue over a valve stent or other cylindrical form circumscribing the valve.  As the vestibule tissue is inverted, the septal shelf muscle is pulled toward the outside wall of the valve.  When the septal shelf has been displaced to the maximum extent possible while maintaining coaption of the valve leaflets, the valve is fixed with a tanning solution.  The resulting valve, after being trimmed and mounted for implantation, has improved flow characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE Equipment for the raising of eels, crayfish and other bottom-living marine organisms, is disclosed.  It comprises a water-filled container for accommodating the marine organisms, in which, beneath the surface of the water, a supporting base is provided, into which tubular hiding receptacles terminate towards the fresh water side.  The marine organisms preferably live in these hiding receptacles in accordance with their habits.  The hiding receptacles for eels extend downwards at an inclination from the opening on the fresh water side.  For raising of crayfish, the hiding tubes extend horizontally away from the fresh water section.  There is a forced flow of water through the hiding receptacles flow of water, especially towards a dirty-water section, so that excrement, feed scraps and other con-taminants are discharged from the tubes towards the dirty-water section. Provision may be made with respect to heating, so that, due to special designs of the supporting base, it is possible to use either slightly or highly contaminated warm waste water for heating purposes.
