Abstract: ABSTRACT OF THE DISCLOSURE         A method is provided herein for manufacturing cartridge cases having a substantially cylindrical outer side wall surface and a tapered inner side wall surface.  The method comprises the steps of initially forming a cup-shaped article having substantially cylindrical inner and outer side wall surfaces, a substantially flat outer bottom surface with an annular chamfered surface joining the flat outer bottom surface to the outer side wall and an inner bottom wall surface.  Thereafter, the cup-shaped article is engaged by a punch element and the punch element forces the cup-shaped article through a series of die members without any intermediate annealing of the article after passage through any of the die members.  The punch element has an outer side wall and a bottom wall, the bottom wall being dimensioned so that the diameter of the peripheral edge of the bottom wall is substantially the same as the diameter of the peripheral edge of the inner bottom wall surface of the  cup-shaped article whereby at least the peripheral edge of the bottom wall of the punch element will contact the peripheral edge of the inner bottom wall surface of the cup-shaped article when the punch element engages the cup-shaped article thereby to align the punch element and the cup-shaped article with one another for forcing the cup-shaped article through the series of die members.  The side wall of the punch element is tapered so as to correspond in configuration and dimension to the configuration and dimension of the tapered side wall surface of the cartridge case to be formed.  The die members, the cup-shaped article, and the punch element are dimensioned so that the cup-shaped article is only subjected to iron-ing during passage through the die members thereby to increase the length of the side wall of the cup-shaped article while reducing the thickness of the side wall thereof.  In this method, the engaging and forcing step is thus performed without annealing the cup-shaped article after passage through and of the die members.

Abstract: "BOOK SUPPORT" ABSTRACT OF THE DISCLOSURE         A book support consists of a book supporting plate and a back plate hinged to the top of the front plate and extend-ing outwardly and downwardly when extended, to form an inverted V when viewed in side elevation.  A cord is secured by each end thereof to the sides of the front plate and extending through guide apertures at the sides of the back plate to be hooked over one of several projections on the back plate to adjust the angle between the plates.  A pair of slide members extend one from each side of the front plate to adjust to the width of the book and a further cord is detachably secured by one end thereof to one of said slides passes across the open book and detachably hooks onto the other of said slides to hold the pages relatively flat.  This cord is disengaged from the other slide when a page is to be turned and rehooked afterwards to hold the pages open and relatively flat.  The holder can be folded relatively flat for storage, without removing the book from the holder.

Abstract: VISBREAKING-ENHANCED THERMAL RECOVERY METHOD UTILIZING                  HIGH TEMPERATURE STEAM                  ABSTRACT OF THE DISCLOSURE             The displacement efficiency of a steam drive process is improved and steam override reduced by rapidly injecting a predetermined amount of high temperature steam via an injection well into the formation to visbreak a portion of the oil in the formation prior to a steam drive wherein steam is injected into the formation via the injection well to displace oil to a spaced-apart production well through which oil is recovered. The visbroken oil provides a more favorable transition of mobility ratio between the phases in the formation thereby reducing viscous fingering and increasing the displacement efficiency of the steam drive. In addition, after a predetermined amount of high temperature steam has been injected into the formation, the formation may be allowed to undergo a soak period prior to the steam drive. The high temperature steam injection and soaking steps may be sequentially repeated for a plurality of cycles.
