Abstract: ABSTRACT OF THE DISCLOSURE           A memory system for a computer detects data errors, address  errors and operation errors to increase the reliability of data stored in the memory system.  Address errors are detected by encoding address parity information into the data check field of each memory location.  A signal is generated in each memory module indicating the status of operations of that memory module and is transmitted to the processor subsystem of the computer for comparison with a signal indicating the status of operations of the processor subsystem to insure that all memory modules and the memory control in the processor are receiving the same commands.

Abstract: ABSTRACT OF THE INVENTION    "A METHOD OF AND APPARATUS FOR TAPPING A FURNACE            CONTAINING A MELT TO BE TAPPED"     The invention relates to a method of and apparatus for tapping a furnace (1) containing a melt to be tapped, e.g. silicon prepared by the reduction of technical quality silicon dioxide with carbon.  The furnace (1) has a tapping pipe (5) which is made of graphite and is electrically heated, so that material contained in the tapping pipe (5) is converted into the liquid phase and the melt can thus run out of the furnace (1) through the tapping pipe (5).  Contamination of the melt is thus avoided.

Abstract: SELECTABLE FOCUS ULTRASONIC TRANSDUCERS          FOR DIAGNOSTIC IMAGING            Abstract of the Disclosure Dual focus ultrasonic transducers are provided having an effective aspheric radiating surface.  The transducers exhibit an elongated focal zone in which the radiated ultrasonic energy is concentrated.  An annular groove separates the piezoelectric material into an inner disc region and an outer annular region for simultaneous activation or activation of the inner disc alone.  When the focus is switched, both the near field limit and the geometric focus are changed to provide near and far focal zones of good lateral resolution.  The focus is changed by a reed switch connection to the two transducer regions, which permits proximity switch control of the transducer operation in a shielded environment for good noise performance.

Abstract: Abstract Wastes, in the form of liquids, solids and slurries, are converted to a mixture of a gas and an inorganic ash by introducing the waste as a finely atomized spray into a zone heated by means of a hot gas.  Contact of the spray particles with the hot gas results in drying the waste and calcining and combusting the dried waste.  The process is particularly useful with wastes containing hazardous materials such as radioactive substances.

Abstract: Abstract of the Disclosure A system for separating at least one constituent from a liquid suspension such as blood induces high velocity flow by viscous drag about the circumference of a spinner having a filtration membrane with pore size selected for the desired constituent.  The high velocity circumferential flow is bounded by a spaced apart shear wall, with a spacing selected relative to the diameter of the spinner and its rotational velocity, also with respect to the viscosity of the suspension, to establish a not-turbulent flow within the shear gap, as substantial centrifugal forces are exerted upon the suspension.  Under these conditions, filtrate               in contact with the membrane is replenished, and filtrate passes through the membrane with minimal adverse effects from deposition and concentration polarization, and with high efficiency because of high shear levels that are maintained.  The filtrate is collected within the interior of the spinner in a conduit system and passed to an outlet orifice.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for cutting tubing suspended in a borehole.  An elongated tubular assembly is provided for suspension in and securement within a wellbore for the chemical cutting of the tubing therein through the discharge of high velocity streams of a highly reactive, incendiary chemical fluid.  The apparatus includes the storage of a halogen flouride, or the like, disposed within a chemical module inter-mediately disposed of propellant and slip assembly modules and a discharge head assembly.  The propellant module is constructed with a chamber containing active burning ignition powder for igniting a slow burning propellant for the generation of gas to pressurize the chamber and cause a linear actuation of the slip assembly responsive thereto for the deployment of a cylindrically segmented slip array to securely engage the adjacent tubing and anchor the apparatus therein.  The generation of the pressurizing gas also imparts a movement of the in-cendiary fluid through a catalyst chamber for causing the fluid to react and discharge through the discharge head assembly for the cutting of the adjacent tubing.  The slip assembly is constructed with a dual taper, gripping teeth configuration for matingly engaging two discrete tubing dia-meters, therein facilitating interchangeable use within conduit of different sizes.  The assembly also includes a pair of rupture diaphragms enclosing the incendiary fluid, which rupture to a substantially full flow opening at a preselected breakthrough pressure to facilitate effective and safe oper-ation of the present invention.

Abstract: A B S T R A C T      A DC-DC converter includes first and second switches to be opened and closed at mutually exclusive times at a predetermined frequency.  The first switch is connected to an inductor and a transformer primary winding so that a first current component from a DC input supply flows through it via the inductor.  A second current component having a sinusoidal component flows through the first switch in response to discharge of energy stored in a resonant circuit coupled to the transformer.  The second component begins approximately simultaneously with closure of the first switch.          The second switch, when closed, is connected so that a bi-directional current component flows through it in response to energy stored in the inductor.  The rectifier is connected between the secondary winding and the load so the secondary winding supplies substantial current to the load.
