Abstract: DRUM BRAKE WITH AUTOMATIC ADJUSTMENT                 ABSTRACT OF THE DISCLOSURE            A drum brake includes a pair of brake shoes and a hydraulic actuator which is engageable with the brake shoes to expand the latter during braking.  The hydraulic actuator carries a pair of elastomeric sealing rings which are deformable during braking as a pair of pistons slidably disposed with the hydraulic actuator are movable upon a braking application.  When braking is terminated, the elastomeric sealing rings return to their original stored configuration thereby retracting the pair of pistons within the hydraulic actuator.  In order to retract the pair of brake shoes with the pistons through a predetermined distance, a first spring engages the pair of brake shoes substantially opposite the hydraulic actuator and biases the brake shoes toward each other while a second spring biases the brake shoes away from each other.  The second spring is carried by a strut on a parking brake actuator and the strut extends from one of the brake shoes to a lever which is pivotally mounted on the other brake shoe.

Abstract: Abstract of the Disclosure A rotary valve for providing control of fluid flow throughout a wide range of pressures and temperatures. The valve includes a pressure-sensitive and temperature-responsive flexible annular seat that cooperates with the valve's flow control element to establish a fluid seal, and a temperature-responsive rigid energizer ring for maintaining both a radial and an axial load on the seat through a wide range of ambient: and low temperatures.  The valve seat includes an annular, radially outward extending support leg that is held in position against a radial surface of the valve's body by the energizer ring, at least one outer annular sealing lip that extends is a generally axial direction from the leg, and a central sealing lip that extends radially inwardly from the support leg toward the flow control element.  At ambient temperatures a portion of the outer sealing lip presses against the flow control element when the valve is closed, and when the temperature is lowered toward the cryogenic range the central sealing lip moves into fluid-tight contact with the flow control element, thereby providing an additional seal at the lower temperatures.  The energizer ring has a generally wedge-shaped cross-sectional configuration, and is held in position in the valve body by a retainer ring that is releasably secured, as by screws, to the valve body for quick and easy servicing of the seat.  The energizer ring has a frusto-conical radial surface that cooperates with the corresponding surface on the retainer ring to maintain the energizer ring constantly wedged tightly against the valve seat, thereby assuring that the seat is retained securely in the valve body and is con-tinually forced against the valve's flow control element throughout the entire range of operating temperatures and pressures.                           -1a-

Abstract: ANTICORROSIVE OVERLAP-COATED IRON OR STEEL MATERIAL          Abstract of the Disclosure Anticorrosive overlapped coatings so far employed for such iron and steel materials as plates, pipes, bars or wires are formed by electroplating an Sn base - Zn alloy layer on the surface of the iron or steel material and applying a chromate-treatment to the alloy layer.  How-ever, this requires a long time for the formation of a plated layer of a suitable thickness, and consequently a reduction of the plating time together with a further improvement of the anticorrosive effect is desired.  The present invention has succeeded in making it possible to reduce the plating time while improving the anticorrosion effect and in improving the productivity by forming the electroplated layer of an Sn base - Zn alloy directly, or over an electroplated layer of Zn, on the surface of the iron or steel material, then forming an electroplated layer of Zn on the layer of the alloy, and further apply-ing a chromate-treatment on the Zn layer.

Abstract: INVENTION:  PROCESS AND APPARATUS FOR OPERATING A GAS   TURBINE ON VAPORIZED FUEL OIL          INVENTORS:  WILLIAM WARREN HOEHING and MEHERWAN P. BOYCE                      ABSTRACT OF THE DISCLOSURE         A system for operating a gas turbine includes a vapor-ized fuel oil unit to generate a gasiform hydrocarbon fuel and a liquid residue, and a turbine VFO fuel system for controlling and injecting the gasiform fuel into the combustor for burning in the presence of combustion air thereby giving increased power output and reduced noxious emissions.  Basically, the process includes providing a supply of fuel oil, vaporizing a portion of the fuel oil in the VFO unit to produce a gasiform hydrocarbon fuel and liquid residue, injecting and burning the gasiform fuel in the combustor and then directing the combustion products to drive the turbine.  In the system, the VFO unit, which is remote from the combustor, includes means for injecting steam and natural gas, both of which are non-oxidizing.  The gasiform fuel is super-heated before injection into the combustor.  The injection orifices of the nozzle are directed between a 30° and 60° angle from the center line of the combustor.  During start-up, the turbine is initially operated by injecting natural gas with gradual switching to VFO until 100% gasiform fuel operation is attained.  A heater jacket on the main fuel line maintains the superheat condition and minimizes the transition time during start-up.

Abstract: ABSTRACT      Extra fine cobalt metal powder (up to about 0.8 microns) having less than 100 parts per million cation impurities is produced by a process in which cobalt pentammine chloride is digested in a dilute ammonium hydroxide solution to form a black precipitate, which is separated and heated in a hydrogen atmosphere to reduce the precipitate directly to cobalt metal powder. The cobalt pentammine chloride may be obtained by di-gesting a cobalt source in hydrochloric acid, adding ammonium hydroxide oxidizing the cobaltous ion to cobaltic ion, and reducing the pH with hydrochloric acid to less than 1.0 in order to precipitate cobalt pentammine chloride.  The final cobalt metal powder is useful, for example, as a starting material in the manufacture of cemented carbides.    D-21,959
