Abstract: ABSTRACT Of The DISCLOSURE          A system for delivering a catalyst into a forced draft entry port of a chemical reaction chamber, such as a fossil-fuel combustion chamber, incudes a container having an aqueous solution of the catalyst.  A suction line extends from an air space above the solution to the entry port.  An intake line at atmospheric pressure enters the container and has an end submerged below the surface of the aqueous solution, the submerged end having a float for maintaining the end at a predetermined distance below the surface and thereby establishing a predetermined back pressure.  A layer of oil floats on top of the aqueous solution and may contain a second dissolved catalyst.  The air from the intake line bubbles up through the aqueous solution and the oil layer absorbing minute quantities of the catalysts which are carried by the air into the reaction chamber.  Rhenium and manganese catalysts improve the efficiency of fossil-fuel combustion such as that of the home oil burner and the automotive engine. Ethylene glycol serves as a surfactant and as as antifreeze agent.  Group-1 chlorides in solution inhibit precipitation of the catalyst by the surfactant.

Abstract: ABSTRACT          A bed pad structure is provided for the prevention of bed sores or pressure ulcers.  The bed pad includes a pouch portion having an upper layer formed from a porous low friction material and a lower layer formed from a flexible impervious sheet material.  The pouch portion is further constructed to enable easy insertion and removal of a lubricated insert in between the upper and lower layers.  Lubrication from the insert can flow through the porous upper layer.  The low friction characteristics of the upper layer plus the presence of the lubricant adjacent the patient substantially prevents friction and related wear which are contributing factor to the occurrence of bed sores.

Abstract: Abstract of the Disclosure Nitriding Grade Alloy Steel And Article Made Therefrom A nitriding grade alloy steel includes aluminum in a range of 0.07% to 0.30% by weight and vanadium in a range of 0.03% to 0.20% by weight.         Prior art nitriding grade alloy steel generally have relied on molybdenum, nickel and other expensive alloy additions to provide nitridability and core hardness.  The alloy steel includes only essential amounts of carbon, manganese, and chromium, in addition to small, controlled amounts of aluminum and vanadium. The alloy steel is not only economical to produce due to the absence of significant amounts of costly alloying elements, but also has a unique combination of hardenability, resistance to loss of hardness during tempering, and excellent nitride response.         Articles manufactured from the new alloy steel are desirably hardened, tempered, machined and nitrided, and are useful in applications requiring high wear resistance and high stress loading.  Such articles include gears, shafts, bushings, couplings and other such articles subjected to severe service applications.

Abstract: METHOD OF PROCESSING AN IRON-CONTAINING DUST OBTAINED IN THE PREPARATION OF IRON OR STEEL Abstract Iron is recovered from an iron containing dust obtained in processing iron or steel by dissolving iron and bivalent metals being present in said dust in an acid. Subsequently the iron is precipitated by adding an alkaline substance or ammonia to adjust the pH to 5 to 8. Before or during precipitating the iron the bivalent ions as present such as zinc, cadmium and lead are converted into a soluble complex by means of a complexing agent. Preferred complexing agents are polyamines, particularly triethylene tetramine being an excellent complexing agent for zinc. The precipitated iron hydroxide is recovered and may be reused. The process may be separated more than once in the same solution, thereby providing a final solution containing considerable amounts of zinc, cadmium, or other bivalent metals which may be separated by boiling or precipitation. The complexing agent may be recovered by destillation after having made the complexes strongly alkaline or by precipitation by adjusting the pH to 1 and recovering the salt of the complexing agent such as a hydrochloric acid salt of the complexing agent.

Precast concrete studs with fasteners protruding from one edge are used to build the framework of the walls while oriented in a horizontal plane, rigid sheet insulation is attached to the out-side of the concrete studs, and wire mesh is laid upon the sheet insulation.  Concrete is then poured onto the insulation, the wire and the protruding fasteners to form a continuous waterproof outer surface.  New top and bottom beams which are bonded to the concrete studs are formed at the same time as the outer concrete surface.

Abstract: IMPROVED MICROWAVE LANDING SYSTEM            Abstract of the Disclosure The invention provides independent guidance and monitoring to be integrated into an MLS landing system and also provides a scaled-down MLS landing guidance system useable at small airports. In both cases an added fixed beam precision guidance system is integrated into the MLS time sequence format. The fixed beam guidance system is based upon the concept of using paired fixed overlapping beams (31,32 and 33,34), sequentially radiated by different fixed antennas (80,81 and 89,90). One pair (31,32) is oriented to left and right of the centerline (36) of the runway, and the other pair (89,90) is oriented above and below the desired glideslope (36'). The first set of paired beams overlap at the centerline (36) of the runway in such a manner that an aircraft approaching exactly on centerline (36) will intercept equal signal intensities to indicate an on-course approach. Conversely when the aircraft is off-course to one side of the centerline (35), it will intercept a stronger signal intensity for the fixed guidance beam (31) which is directed to that side of the centerline and a weaker signal intensity for the fixed beam (32) which is directed to the other side of the centerline. Similar operation is provided by the overlapped guidance beams (33,34) operating in the elevation mode.

Abstract: ABSTRACT OF THE DISCLOSURE    A quarter-turn plug valve has an inverted and tapered frustoconical body cavity and plug.  The valve body has a through-flow passage with ports opening into said body cavity.  The tapered plug has a valve stem and a through-flow passage.  The valve seats surround the ports and extend from the walls of the tapered valve cavity toward the plug.  The plug, when seated in closed position, is in physical contact only with the annular tapered faces of the valve seats.  The valve stem contains acme or square threads near the bottom to engage with a bonnet threaded at its lower end.  The bonnet extends axially along the valve stem and has a projecting flange near its midpoint, which seats on a gasket placed between it and the valve body flange.    When the plug is properly oriented in closed position, the adjustable bonnet is turned on the threads of the valve stem with the stem fixed until it seats on the valve body with the desired downward thrust.  A bonnet flange is then bolted to the valve body to hold the bonnet and stem and plug assembly properly adjusted and seated in closed, no-flow position inside the valve cavity.  The valve stem is square at the top, with the plane of one side of the square being in line with the opening of the flow-through passage.  Therefore, a handle mounted on the valve stem will indicate whether the valve is in open-flow position or in closed, no-flow position.

Filed: 1992-09-30
Abstract: A dispensing device for dispensing at least two fluids comprises a housing (12,22) of a pistol-like configuration having an integral handle (50), in which a spring-biased trigger (60) is received. Within the housing (12,22) of the dispensing device (10), two syringes (80,81) are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover (22) of the housing is closed, the motion of the trigger (60) relative to the handle (50) is transmitted to a toothed rack which cooperates with a propeller body (70) in a ratchet-like manner. The ratchet-like cooperation allows a uni-directional motion of the propeller body (70) and prevents a motion of the propeller body (70) in the opposite direction. Provided the cover (22) is not closed, the motion of the trigger (60) relative to the handle is not transmitted to the propeller body (70), and any unintentional dispensing of fluids from the dispensing device prior to the preparing of the dispensing device for use by closing the cover (22) is consequently prevented. <IMAGE>   <IMAGE>
