Abstract: Abstract of the Disclosure An electromagnetic switching apparatus having a switch position indicator is disclosed.  The switch position indicator is in functional connec-tion with the contact carrier and protrudes beyond the cover of the switching apparatus in at least one switch position.  The switch position indicator is coupled to the contact carrier by apparatus such that the switch position indicator travels a greater distance than the movable contact carrier in going from at least one switch position to another.  Thereby, an unequivocal switch position indication can be obtained, particularly in an open contact condition which satisfies switch disconnect function conditions, thereby making the switching apparatus useful as a disconnect switch.

Abstract: IMPROVED MECHANICAL SEAL ASSEMBLY            Abstract:      A mechanical seal assembly having a rotatable sealing ring means (18) mounted for rotation on a shaft and a stationary sealing ring means (20) connected to a housing flange, the sealing ring means having opposed sealing surfaces (22,24).  The assembly also has means (42) urging the sealing surfaces toward one another.  The rotatable sealing ring means (18)  is of stepped configuration and constructed as an integral pair of equal axial length ring portions (A,B), one portion having its inner and outer diameters larger than the respective diameters of the other.  Generally, the ring portion having the smallest inner and outer diameter is that ring portion having the sealing surface - one that opposes  the  sealing  surface  of  the  stationary sealing ring means.      The degree of deflection of the sealing surface because of hydraulic load or pressure can be select-ed by selecting the diameters of the pair of ring portions, i.e.,  if the ring portions have substan-tially the same shrinkage, the sealing surface will remain substantially flat; if the shrinkage of the ring  portion with  the  largest  inner and outer diameters is more than the other ring portion, the seal surface will become convex; if the opposite relationship of the cross-sections is selected, the seal surface will become concave.

Abstract: ABSTRACT OF THE DISCLOSURE      A NMR apparatus for determining the relationship between work output of an exercising body member and the steady-state capability of oxidative phosphorylation of the muscle tissue as measured by the PCr/Pi ratio in the tissue. The apparatus includes the large hollow magnet of the NMR system, with a radio frequency probe mounted therein, arranged to underlie a human limb, such as an arm, inserted in the magnet from one end.  Adjacent to the opposite end a Cybex ergometer is mounted.  A hand lever is pivotally mounted in the magnet and is connected by a link bar to the drive arm of the ergometer.  The subject inserts his arm in the magnet and grasps the hand lever, performing controlled work strokes at uniformly spaced short intervals over a selected length of time, such as 10 minutes, observing the output trace of the ergometer and maintaining a con-stant work output intensity with each stroke.  The NMR apparatus provides curves of the NMR response at 24.3 MHz and a magnetic field of 20 kg, showing the intensities of the phosphorus-containing components of the muscle tissue, including PCr and Pi.  This enables accurate measurement and monitoring of the work output from the muscle simultaneous-ly with the generation of the phosphorus NMR response curves.  A curve may be plotted showing PCr/Pi versus time, which affords criteria of muscle performance.  Another use-ful curve may be plotted showing muscle unit volume work rate in terms of joules/sec versus Pi/PCr, also capable of detecting biochemical abnormality, muscle dystrophy or vascular disease.
