Abstract: BRAKE SHOE GUIDE AND WHEEL CYLINDER       RETAINER FOR A DRUM BRAKE                        ABSTRACT OF THE DISCLOSURE           A drum brake assembly includes a backing plate which supports a pair of brake shoes and a hydraulic actuator cooperates with the pair of brake shoes to move the latter to a braking position.  An anchor pin extends from the backing plate to oppose torque developed by the pair of brake shoes during braking.   In order to align the pair of brake shoes with the hydraulic actuator, a single clip is carried by the anchor pin and the clip opposes axial movement between the backing plate and the pair of brake shoes opposes separation between the backing plate and the hydraulic actuator.  In an alternative embodiment the single clip forms a hook at one end to releasably engage the backing plate.

Abstract: METALLIC CORE PANEL        AND METHOD OF MAKING SAME           Abstract of the Invention:         A panel includes metallic face sheets maintained in operative relationship with each other by a metallic core structure.  The core structure consists of a plurality of securement core strips which may be inter-nested or juxtaposed to provide a honeycomb core configuration.  Structural integrity is created by the provision of internally generated welds which fasten securement portions of the core strips in operative relationship with the face sheets, but which can be terminated inwardly of the outer surfaces of the face sheets resulting in a very small volume of face sheet material being cast into a weld nugget and being heat affected and maintaining the integrity of the face sheets while, nevertheless, providing maximum structural strength and eliminating face sheet thickness limitations.         Also disclosed is a method of fabricating the metallic panel which includes the steps of internally generating the weldments so that, by minimum pressure and minimum energy, discrete welds are formed which fasten the securement portions of the core strips in operative relationship with the face sheets while greatly reducing the dimensions of the weld nuggets in comparison with the nuggets which result from the utilization of prior art external welding techniques.

Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus is disclosed for sorting fibrous suspensions, operating on the principle of a pressurized screen with rotating hydrofoils.  The processed suspension is guided over the screen such that the component of the flow speed parallel to the surface of the screen is a multiple of the flow speed through the passage openings in the screen.  The effect is achieved by providing the sorter with an inlet chamber (60) whose cross-sectional area size in the plane perpendicular to the axis (42) of the rotor decreases in the direction from the inlet to the outlet, the said size at the inlet being smaller than the sum of cross-sectional areas of the passages through the screen.          The invention results in an improved performance of the machine from the standpoint of reducing the clogging of the screen passages thus allowing a modification in the size of the hydrofoils to reduce energy consumption.  The separation effect of the machine is also improved.

Abstract: ABSTRACT OF THE DISCLOSURE      This application discloses a material metering device and method for repetitively charging consistently accurate quantity charges of a lubricant retaining and wicking material to lubricant reservoirs of dynamoelectric machine bearings.  A metering head is movably supported on a base for motion toward and away from a bearing and its support while both are held in alignment with the metering head.  The metering head includes a dispensing chamber which may be sealingly coupled to the bearing support structure.  The chamber receives lubricant retaining material from a source with excess material returning to the source.  A valving arrangement inter-rupts the supply of material without substantially changing either the volume or pressure of the material in the dispensing chamber.  An evacuation passage material flow path from the chamber to the bearing support structure or other workpiece is established and the material is extruded from the chamber.  One preferred method includes supplying a compressible mixture of lubricant and wicking material to a chamber under con-sistent conditions, isolating the chamber from the mixture supply, opening an evacuation port for evacuat-ing the chamber, evacuating a preselected amount of material from the chamber, and closing the evacuation port without concomitantly causing or contributing to the evacuation of residual amounts of material from the chamber or from evacuation passages.

Temperature differential means comprise the temperature of the ocean water at the ocean surface providing heat input into said evaporator means 14 whereas cold ocean water pumped from the depths of the ocean provides the cooling means to said condenser 26. The difference in temperature between this warm ocean water at the ocean surface and the cold water from the depths of the ocean thus provides the heating and cooling means for powering said apparatus,  Evaporation in the condenser 26 and condensing in the said condenser 26 when the air has been removed from the apparatus by means of a vacuum pump means 24 leaves only water vapor in the system.  This evaporation and subsequent condensing of the vapors from the ocean water, which are essentially low temperature steam, results in a mass flow of vapors from the evaporator means 14 to the condenser means 26 through the conduit means 18 connecting same.  These vapors when condensed in the con-denser means 26 become distilled or desalinated water since only water vapors are carried through the apparatus and the salt, minerals, etc. are retained in the ocean water in the evaporator 14.

Abstract: ABSTRACT A hot  raw gas stream, as produced by the partial oxidation of a solid carbonaceous fuel such as coal, is partially cooled and cleaned to remove entrained solid matter and slag.  A novel gas - gas quench cooling and solids separation apparatus is employed.  The apparatus comprises a closed cylindrical insulated vertical pressure vessel containing a lower quench chamber in communication with an upper solids separation chamber.  The hot raw gas stream is cooled in the lower chamber to a temperature   below the initial deformation temperature of the entrained slag by impinge-ment and direct heat exchange with an oppositely directed coaxial stream of cooled, cleaned, and compressed recycle quench gas.  The stream of cooled gas leaving the turbulent lower chamber passes up through a choke-ring into the compar-atively calmer upper chamber counter-currently with solid slag-droplets which separate out by  gravity. Residual solid particles are removed from the gas stream by at least one cyclone separator located in the upper chamber.  A portion of the cooled and cleaned gas stream leaving the vessel, with further cooling and with or without further cleaning downstream is recycled back to the vessel for use as said quench gas.  Slag particles and other solid matter that are separated within the prosier vessel are removed at the bottom of the lower chamber.
