Abstract: ABSTRACT             There is provided a magneto-hydrodynamic generator which utilizes pulsating combustion.  The generator has a central combustion chamber and a radial expansion chamber annularly surrounding the combustion chamber and communicating with it.  The expansion chamber is defined between two opposing walls.  A combustible fuel mixture is introduced into the combustion chamber and pulsating combustion is initiated in the combustion chamber, so that gas flow in the expansion chamber fluctuates with time.  Means are provided for ionizing gas in the expansion chamber, and further means are provided for applying an external magnetic field to the expansion chamber.  Finally, electrically conductive means are provided for extracting electrical power from the ionized fluctuating gas flow in the expansion chamber.

Abstract: FLUID-ASSISTED CORE-RELEASE    METHOD AND APPARATUS                     Abstract An apparatus for assisting in the removal of an in-jection-molded  article from the core of a mold is disclosed in combination with a molding machine in which the mold core is fixed to a moving platen and an ejector mechanism is supplied which mechanically removes the article from the core.  The assisting apparatus includes a conduit leading to a surface of the mold core which defines the bottom of the article formed.  A piston and cylinder is connected to the conduit, the interior of the cylinder being dimensioned to be approximately equal to the interior volume of the article formed.  The cylinder is fixed with respect to the platen, while the piston is fixed with respect to the ejector apparatus.  As the ejector moves with respect to the mold core so as to mechanically strip the molded article from the core, the piston moves within the cylinder which is filled with air at approximately 1 atmosphere, thereby causing the air within the cylinder to be introduced into the conduit and thus into the void developing between the bottom of the formed article and the mold core, thereby preventing deformation of the formed article.

Abstract: MEMORY PAGING SYSTEM IN A MICROCOMPUTER                     Abstract In a microcomputer system having a main memory accessed by both the CPU and the CRT controller, a page register system receives page bits defining both CPU and CRT pages from the CPU.  The CPU page bits are combined with lower order address bits from the CPU for CPU access cycles, and the CRT page bits are combined with lower order address bits from CRT controller for CRT access cycles.  Both the CPU and CRT controller can access any of the pages in the memory.  For compatibility with higher level systems, the CPU may provide addresses in a range outside the range of addresses for the memory.  When a decoder detects such addresses, it directs CPU address bits, corresponding in order to the CPU page bits, to address the memory instead of the CPU page bits.
