Abstract: ABSTRACT   A method of hormonally treating menopausal (including perimenopausal and post-menopausal) disorders in women, a composition, and a multi-preparation pack therefor.  The administrative regimen to which the pack is particularly adapted comprises continuously and uninterruptedly administering a progestogen to a woman while cyclically administering an estrogen by using a repetitive dosage regimen.  This regimen calls for administering the estrogen continuously for a period of time between about 20 and about 120 days, followed by terminating administering the estrogen for a period of time between about 3 and about 7 days.  Alternatively, both the progestogen and estrogen may be administered for the full treatment period without interruption.  The regimen avoids many of the problems associated with the administration of estrogen alone or with progestogen administered according to conventional regimens, and also avoids problems associated with such conventional regimens by maintaining the estrogen and progestogen at low daily dosage levels of between 0.005 mg and 2.5 mg estrogen and 0.25 mg and 30 mg progestogen.

Abstract: ABSTRACT OF THE DISCLOSURE           There are disclosed two embodiments of a wire line tool for use in running and/or pulling a well tool within a well bore.  In each embodiment, latches are carried within slots about a body of the running tool which is adapted to be raised and lowered on a wire line. The latches are yieldably urged from inner positions, in which their outer ends are adapted to move into the well tool, to outer positions in which their outer ends extend into a groove in the well tool when opposite thereto.  The outer ends of the upper sides of the latches have bearing surfaces which, when their outer ends extend into the groove, are engageable with the upper end of the groove to support the well tool from the wire line tool, and which are so related to bearing surfaces on the lower sides of the latches which are slidable over guide surfaces on the lower sides of the slots as to prevent inward movement of the latches when the well tool is raised or lowered with the wire line tool.  The latches are forced inwardly to remove their outer ends from the groove, and then retained against outward movemnent, in response to downward jarring of the body and subsequent lifting of the body with the wire line to permit the tool to be retrieved from the well tool.

Abstract: ABSTRACT OF THE DISCLOSURE     A reciprocating piston type refrigerant compressor includes a com-pressor housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is reciprocated by a wobble plate driven by a cam rotor mounted on a drive shaft. The cam rotor includes an adjustable slant plate with a sloping surface at an adjustable slant angle in close proximity to the wobble plate. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the slant angle of the sloping surface. The slant angle of the sloping surface is adjusted in response to the change of pressure in the crank chamber. The crank chamber communicates with the suction chamber through a passageway and a valve control mechanism controls the opening and closing of the passageway. Thus, the capacity of the compressor of the present invention can be adjusted by changing the slant angle of the sloping surface of the slant plate in response to operation of the valve control mechanism.

Abstract: ABSTRACT     A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communi-cating the outlet of the atrium chamber with the inlet of the ven-tricle chamber, a first one-way valve in the passage adapted to per-mit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         This is a process of fabricating directionally solidified turbine blades for combustion turbines. It is an improvement to the type of process where a mold con-taining molten metal is cooled in a controlled fashion such that solidification occurs slow enough to allow directional solidification beginning at the airfoil end.          In the improved process solidification is monitored and magnetic mixing of the remaining molten metal is started at approximately the beginning of solidification of said root section and the rate of cooling of said blade is increased to a rate faster than at which directional solidification occurs.  A blade is produced with a direc-tionally solidified airfoil section and a fine grained root section and without a substantially inhomogeneous portion at the interface between the airfoil and root sections.
