Abstract: ABSTRACT OF THE DISCLOSURE           A tool for use in removing broken or inoperative screw fasteners.  The tool has a tubular-shaped extension at one end with cutting teeth projecting axially from the extension.  The teeth can cut around a fastener when the tool is rotated in one direction to provide a stub end on the fastener over which the extension fits.  The extension is then tightened on the stub end and teeth, extending radially inwardly from the extension, tightly grip the stub end so that the fastener can be unscrewed on reverse rotation of the tool.

Abstract: D# 76,187-C3-FB                  PARTIAL OXIDATION PROCESS                         ABSTRACT      A partial oxidation process and control system for continuously producing synthesis gas, fuel gas or reducing gas in which one process fuel is replaced by a different fuel without shutting down or depressurizing the gas generator.  This multifuel process is not tied to one particular fuel and reacts slurries of solid carbonaceous fuel and/or liquid or gaseous hydrocarbonaceous fuels. Suitable burners for introducing the feedstreams into the gas generator comprise a central conduit means radially spaced from a concentic coaxial outer conduit having a downstream exit nozzle, and providing a coaxial annular passage means therebetween.  In other embodiments a two-section burner having a high turndown feature is employed that comprises a central conduit; a central bunch of tubes positioned in said central conduit; an outer conduit coaxial with said central conduit and forming an annular passage therewith; and an annular bunch of tubes positioned in said annular passage.  A control system is provided for switching the type of reactant fuel stream flowing through either the central conduit means or the annular passage means of the burner or through either one or both sections of a two-section burner and adjusting the flow rates of the reactant stream of free-oxygen containing gas with or without mixture with a temperature moderator and if necessary to introduce supplemental H2O into the reaction zone to maintain the temperature and weight ratio H2O/fuel in the reaction zone at design conditions for the partial oxidation reaction without stopping production of the product gas.

Abstract: Abstract There is provided a method and an arrangement for restricting local variations in ground level in the vi-cinity of surface water drains and manholes, at locations where the freezing and unfreezing of the ground causes the ground and parts of the drainage system located therein to move. To this end, the arrangement comprises a drain cover-support means arranged to be anchored in the surface  ground layer in a conventional manner, and provided with a tubular part which projects down into the drain and is axially moveable relative thereto. A supporting element is arranged around the tubular part of the drain cover-support means, the supporting element being axially displaceable relative to the tubular part, while being guided by the upper part of the drain, and is arranged to be anchored in the surrounding ground layer. The supporting element preferably has the shape of a circular plate or disc, which abuts the tubular part substantially tightly, and the outer diameter of the plate or disc is about twice that of the diameter of the drain.

Abstract: ABSTRACT     An improved reaction process and apparatus for the cata-lytic hydrogenation of coal to produce hydrocarbon liquid and gas products.   In the process  the concentration of unconverted coal solids in the reactor is increased by use of a coal solids deflecting means such as a baffle criti-cally located with the upper portion of the reactor upstream of the effluent stream withdrawal conduit opening.   Such deflection means provides for an increased concentration and prolonged reaction of coal solids usually larger than about 30 microns in the reactor liquid to produce increased con-version  and  yield  of  hydrocarbon  liquid  products,  and thereby  reduces  the  need  for  liquid-solids  separation downstream from the reaction step.   The solids deflection means preferably comprises a solid baffle attached to the reactor effluent withdrawal conduit upstream of its opening, and is preferably made removable from the reactor upper end.

Abstract: ABSTRACT OF THE DISCLOSURE A process and a product produced thereby, for forming rod or bar or tube stock or strip, comprising a sheath and a densified dispersion strengthened metal core.  Powdered dispersion strengthened copper is put into a metal can and compressively reduced to size and density, the relationship between the tensile strength of the core when fully densified and the cold worked tensile strength of the can being important to the nature of the product.  The product is particul-arly useful in the fabrication of electrodes for automatic resistance welding machines used, for example, in the manufacture of automobiles.  The process in-volves a lower capital expenditure initially and a lower labor content than the previously practiced extrusion method.

Abstract: ABSTRACT OF THE DISCLOSURE    A receiver accurately measures the Doppler shift of a radio signal from a transmitter having a known frequency and moving with respect to the receiver by using the signal from another transmitter of known frequency as a reference.  The signals from the two transmitters are received by a single antenna, separated, and processed in separate channels.  In a typical appli-cation using Global Positioning System satellite signals, each signal is discretely extracted by auto-correlation with its own pseudorandom noise signal, filtered, amplified, and applied to second mixers in phase locked loops in the respective channels.  The two resulting second IF signals are applied to an output mixer whereupon the resulting difference output signal represents the difference in frequency between the two Doppler signals.
