Abstract: Abstract Of The Disclosure A diaper fastener is provided comprising a strip of tape having a pressure sensitive adhesive disposed over a surface thereof.  A unit is re-movably secured to the strip in a longitudinally central portion thereof, the unit providing an exposed surface, facing away from the strip surface and having limited affinity for the adhesive.  An end portion of the strip is folded over and in contact with the exposed unit surface, the unit compris-es outer and inner layers of web each of which has a surface which has limited affinity for the adhesive and which faces away from the other layer.  The outer layer includes tabs projecting longitudinally beyond the ends of the inner layer and secured to the strip surface.  In use, the end portion of the strip is peeled from the unit and used to affix the diaper to a baby.  After the diaper is soiled, the fastener is torn across its width in its longitudin-ally central region to expose edges of both layers of the unit.  These may then be peeled back or removed, leaving a fresh mass of adhesive exposed on the tape for retaining the diaper in a rolled bundle.

Abstract: ABSTRACT         Superalloys such as those with a nickel or cobalt-base reach their maximum practical operating temperature in the neigh-bourhood of 1000°C.  Efforts have been made to raise this oper-ating temperature by using reinforcing materials such as filaments of tungsten or other strong refractory materials.  Migration of alloy constituents into these filaments may have a detrimental effect on their strength.  Coatings are proposed which prevent this migration.  Such coatings may consist of materials such as hafnium carbide, hafnium nitride, titanium nitride, zirconium carbide or zirconium nitride.

Both teeth of each cutter element may be of relatively narrow transverse dimensions or thickness as well as minimum taper,  such as  40° or less, and the circumferential spacing between adjacent cutter elements may be relatively wide without unduly weakening said teeth, whereby a drill bit having such cutter elements may be utilized in varying formations, from relatively soft to relatively hard, so as to minimize the necessity of replacing the bit before exhauston of its usefulness.

Abstract: ELECTRICAL LOADBREAK ARC QUENCHING AND CONTAINING ASSEMBLY     ABSTRACT           An electrical loadbreak device in which the arc established between two loadbreaking contacts is first confined to a narrow gap between the confronting surfaces of two insulating members formed of arc quenching material before reaching a larger volume space.  Spiraled grooves are formed in one of the con-fronting surfaces to provide channels of increased length for the arc such that the arc voltage may be higher and to increase the exposure of the arc to the arc quenching material.  The grooves further act to provide "spoiling" action to create turbulence in the hot gases.  The hot gases emitting from the grooves impinge upon a baffle which is contoured to promote further turbulence and cooling of the hot gases.

Abstract: SYSTEM FOR HANDLING HIGH SULFUR MATERIALS                     ABSTRACT OF THE DISCLOSURE         Sulfur oxides have a strong affinity for free lime and readily form gypsum anhydrite.  By utilizing 2200° F. or higher on-gas containing reduced quantities of sulfur to the preheat zone of a material treating apparatus, large quantities of sulfur can be removed from gases evolved in the rotary kiln.          Utilizing lower sulfur content on-gas to preheat will substantially improve the ability of the system to lower both sulfur and alkali levels in the clinker.  Substantially free lime in the form of fines is introduced into the kiln off-gas stream to form gypsum anhydrite which is removed and has the potential to be utilized as a by-product.  Essentially all of the remaining gaseous sulfur that has not been absorbed by the lime bearing dust is absorbed by the free lime in the pellets in the preheat zone of a material treating apparatus.

Abstract: Abstract A passenger car deriving all or a part of its motive power from the wind through a system of one or more rigid vertical airfoils symmetrically aligned with respect to the fore-and-aft axis of the car. The relative wind velocity acting on the airfoil system under typical conditions produces a force tending to propel the car forward. The production of this sailing force occurs automatically, without requiring any adjustment of the airfoil system. The sailing force can be increased by having a tall airfoil system, which retracts to a lesser height for convenience in garaging or for safety in high winds. The wind-derived sailing force can signif-icantly improve the fuel economy of a car using this invention, and in some applications of the invention, it can enable the car to cruise at a respectable speed in average wind conditions on wind power alone. When the car is traveling at speeds less than the maximum speed obtainable from the existing wind conditions, the excess wind power can be used to charge an energy storage device, from which energy can later be withdrawn as required to propel the car in periods of insufficient wind or when greater acceleration is desired.
