Abstract: ABSTRACT OF THE DISCLOSURE       This invention concerns a method of controlling mill-motor speed in a cold tandem mill.  During unsteady phases of rolling operation such as threading, rolling speed acceleration and/or deceleration, and tail out with respect to the coil being rolled, mill motors are so con-trolled as not to perform drooping characteristic action except under certain specific conditions, and at threading phase in particular, motors in individual stands are so controlled as to revolve at a uniformly decreased speed, whereby final gauge control accuracy can be improved with respect to top and bottom end portions of the coil and such troubles as coil cut and the like can be effectively prevented.

Abstract: ABSTRACT:            "Apodized ultrasound transducer".     An ultrasound transducer for medical pulse echo applications is apodized by causing the level of response to vary as a function of position on the transducer aper-ture. In a preferred embodiment the response varies as a Gaussian function of distance from the center or center line of the transducer so that the response at the edge of the transducer is approximately 30% of the response at the center or center line. The response may be varied by causing the polarization of a piezoelectric ceramic trans-ducer to decrease as a function of distance from the acous-tic axis. This is achieved in that the transducer comprises a matrix of parallel rods (80) of piezoelectric ceramic in an inert binder (82), The polarization, the composition, the cross-section or the spacing of the rods may vary as a function of distance (X) from the center (C) of the transducer.

Abstract: BIB HAVING SEGMENTED NECK-APERTURE PERIMETRIC EDGE     ABSTRACT       A bib having a neck-accommodating aperture defined by a segmented perimetric edge: ie, a segmented neck-aperture peri-meter. The neck-accommodating aperture is generally oval-shape and the sheet material from which the bib is constructed has a plurality of bifurcations such as slits or notches which extend generally radially outwardly from the perimetric edge of the neck-accommodating aperture. Each pair of adjacent bifurcations define a portion of bib material which is attached to the parent bib material along only a proximal-end-defining line and which portion is designated a petal. The petals are readily conformable to a range of neck sizes and will, due to inherent resilience of the bib material, maintain a comfortable fit even during infant neck contortions. In an exemplary embodiment, the distal end portions of such petals are doubled under and have their distal ends secured adjacent their proximal ends to obviate raw cut edges of such portions from contacting users' necks.

Abstract: ABSTRACT OF THE DISCLOSURE A current sensor for sensing the total DC cur-rent flowing in the DC rails of a multiphase converter circuit.  The current sensor comprises two current trans-formers coupled to the AC power lines of the converter and another current transformer coupled to the circuit path of a freewheeling diode connected across the DC rails of the converter.  An indication of the total DC current flowing through the converter is obtained by summing an indication of current flowing in the AC power lines of the converter and the instantaneous pulsed DC current flowing in the DC path of the converter during periods of non-conduction of the switching SCR's in the converter.  The combination of the two currents are summed by a summing resistor thereby to generate a voltage signal proportional to the instan-taneous level of the total DC current flowing through the converter.

Abstract: ABSTRACT OF THE DISCLOSURE         Type 0 erythrocytes are produced from certain sub-types of A erythrocytes or type AB erythrocytes by contacting the same following equilibration of a pH of 5.6 - 5.8 with an .alpha.-N-acetylgalactosaminidase, preferably obtained from an avian liver, for periods sufficient to convert the A antigen in the erythrocyte to the H antigen.  Following removal of the enzyme, the erythrocyte is re-equilibrated to a pH of 7.2 - 7.4.  As a result, there is obtained 0 type erythrocytes characterized by a 60 to 90 percent ATP level based on the level of ATP  in naturally occurring 0 or AB erythrocytes.  Beginning with certain A cells one obtains synthetic 0 erythrocytes character-ized by a terminal .alpha.-fucose moiety, 0 antigenicity, and the absence of A antigenicity.  Beginning with A2B erythrocytes, one obtains B erythrocytes by the same process characterized by the absence of A antigenicity, greater H antigenicity than naturally occurring A2B cells, the presence of B antigenicity and the aforedescribed ATP levels.
