Abstract: A B S T R A C T        A skate guard designed to extend longitudinally along the bottom edge of the skate blade is shaped to define ?? upwardly opening groove to receive a skate blade.  Over part of its length the groove narrows toward its upper opening to a transverse dimension less than the thickness of the skate blade.  The guard is made of flexible resilient material whereby when a skate blade is inserted in said groove the material of the guard is resiliently biased outwardly by said blade and acts to grip it. Preferably the guard is shaped so that, when so biased by the blade, the lower surface of the guard is concave downward in transverse cross-section.

Abstract: METHOD OF MAKING A SWIVEL HOOK     ABSTRACT OF THE DISCLOSURE       A method for making a swivel hook which has a hook member with a frustoconical projection terminating in a cylindrical extension of diameter less than the smaller diameter end of the frustoconical portion.  The mounting member for the swivel hook has a frusto-conical hole into which the frustoconical projection is fitted.          The elements of the swivel hook are cast of a metal, or molded of a plastic, in such a manner that the bearing surfaces of one of the elements forms a part of the die for the bearing surface of the other element.  During the casting or molding process, the cylindrical extension is beyond the frustoconical hole, and the elements are moved relative to each other following casting or molding to move the cylindrical extension into alignment with the frustoconical hole.

Abstract: 27,892 TITLE:         PREPARATION OF DIALKYLDITHIOPHOSPHINATES         ABSTRACT OF THE DISCLOSURE                  Dialkylphosphine is added to a mixture of sulfur and water at 50-90°C.  After approximately 25% of the dial-kylphosphine is charged, an alkali, such as sodium hydroxide, is added to neutralize the dialkyldithiophosphinic acid that forms.  At this elevated temperature the neutralization reac-tion proceeds rapidly thereby preventing any alkali from reacting with the sulfur to form sulfides.  Dialkyldithio-phosphinate yields from this process are on the order of about 95-98%.

Abstract: ABSTRACT OF THE DISCLOSURE          A method and a device for cutting or breaking a plurality of light waveguides which are contained in a cable characterized by clamping each of the light waveguides at spaced points to hold a portion of the waveguides between said points parallel to each other, positioning the light waveguides extending between the points over an anvil with each of the light waveguides being parallel to one another, applying a vertical force to each of the waveguides at a point on one side of the anvil to apply an axial prestress to each of the waveguides extending across the anvil, notching each of the prestressed light waveguides at a point in contact with the anvil and subsequently applying a common tension force to each of the waveguides at the other side of the anvil to cause separation of each of the waveguides at its notch.  A known device uses a spring arrangement to tension the light waveguides and cuts and breaks them one by one.  The present invention uses weights to push rods vertically to prestress the waveguides.  All the waveguides are then notched, after which an axial force is applied to break all the light waveguides at the notch locations.

A CO rich flue gas is recovered from the low temperature regeneration stage and a CO2 rich flue gas is recoveredfrom the higher temperature regeneration stage.  The temperature of the catalystmixed with the residual oil feed is sufficient to obtain substantially complete vaporization of the residual oil charge.  A special arrangement of apparatus is provided in the lower portion of a riser conversion zone to obtain the intimate vaporization contact between residual oil feed and the high temperature catalystcharged to the riser.
