Abstract: ABSTRACT OF THE DISCLOSURE           Felt belts normally used in paper making are condition-ed after the newly formed paper is removed, by passing the belts over a narrow slot in a box under vacuum which extracts moisture and/or contaminants so that the belt is ready for reuse.  Stain-less steel rods or the like are provided on each side of the slot and act as support guides for the belt, but these rapidly become worn and the sharp edges formed when the rods become worn, cut the belt which is a relatively expensive item in paper making machinery.          The present invention consists of holders detachably secured to the top of the box with the holders detachably supporting steel rods covered with a hard ceramic coating which resists wear.  Fur-thermore, the rods are designed to be repositioned when the coating does wear, in order to provide the use of more than one working sur-face thus extending the life of the rods.

Title: Fan with noise reduction
Inventor: PATEL JAY
IPC: F04D29/66
Filed: 1975-06-27
Granted: 1978-10-24
Abstract: ABSTRACT OF THE DISCLOSURE           A fan for moving a gaseous fluid, e.g., air, is described in which the high audible frequency noise resulting from the phenomenon occurring at the trailing edges of the blades, known as vortex shedding, is reduced.  This is accomplished by notching an edge of each of the blades so that the pattern of vortices leaving the blade, which causes the noise, is disturbed and a turbulence condition engendered.  The turbulence distributes the pressure fluctuations resulting from movement of the blades through the fluid over a relatively broad band of frequencies and reduces the annoying noise frequencies.  Various notch configurations are disclosed.

Abstract: Abstract of the Disclosure A process for dehalogenation of alpha halogenated car-bonyl compounds and/or the prevention of the formation of such.  The process for dehalogenation generally comprises causing there to be in solution the halogenated compound, cuprous ions (such as from cuprous chloride) and hydrogen ions (such as from hydrochloric acid), the process to be conducted in the absence of molecular oxygen, or, if mole-cular oxygen is present, there being an excess of cuprous ions sufficient to completely react with the molecular oxygen present.  Such can also be used to suppress forma-tion of halogenated carbonyl compounds in processes where conditions exist which favor such formation.

Abstract: ABSTRACT OF THE DISCLOSURE       A semi-automatic takeoff flight control system for auto-matically capturing a predetermined takeoff pitch attitude at a predetermined pitch rate during the aircraft takeoff rotation maneuver.  In response to the manual rotation command from the pilot, control circuitry generates a pitch rate command to the elevator, limited to the predetermined pitch rate.  As the craft rotates to an intermediate pitch attitude less than the desired predetermined takeoff climb attitude, circuitry is included to provide a pitch attitude command with regard to the predetermined reference attitude, which by virtue of rate, displacement, and integral control provides asymptotic capture of the predetermined reference attitude.

Abstract: GRATE PREHEATER KILN SYSTEM                  ABSTRACT OF THE DISCLOSURE         Grate burner fuel supplies additional heat to the grate preheater for accomplishing more calcining.  A cooler recoup system directs cooler recoup air to the grate fuel burner as preheat combustion air for the fuel burner.  The cooler recoup air is also directed to the grate preheat zone as preheated combustion air for fuel in the pellet bed.  Cooler recoup air is also directed to the drying zone.  The cooler recoup system is controlled so that excess cooler recoup air is bypassed to the waste gas system to dump excess air.  Also, a cooler recoup fan speed or damper is regulated to control kiln firing hood pressure by varying the flow.  In addition, there is provided the cooler recoup excess air bypass damper for controlling duct pressure to stabilize air flow in the system by varying the flow to the waste gas system.  The dis-closed apparatus operated according to the method herein dis-closed provides improved fuel economy, more effective control and reduction in waste gas, thus reducing heat consumption to provide improved fuel economy with better control of the pre-heating and drying operation.

Abstract: CONTINUOUS CASTING OF METAL STRIP BETWEEN                MOVING BELTS     ABSTRACT OF THE DISCLOSURE for supporting and cooling the reverse surfaces of belts in apparatus for continuously casting metal strip be-tween such belts, means enclosing the reverse surface of a belt includes a multiplicity of guiding faces that are distri-buted closely both crosswise and lengthwise of the belt to de-fine an intended belt path, and that have nozzle openings through which liquid coolant is projected against the belt, rapidly flowing out in a layer over the guiding face and being withdrawn at localities close to all of the guiding faces. The belt, which may be forced toward the faces to stabilize it in its desired path, thus rests on a layer of rapidly moving liquid coolant, which affords efficient heat removal and an essentially complete liquid bearing, such apparatus and pro-cedure being also deemed applicable to cooling other sur-faces. The high velocity coolant layer can be extended around part of the curved followed by the belts returning to enter the mold space; thus or otherwise a liquid bearing can be provided along this return belt path approaching the mold entrance, avoiding large pulleys that interfere with the use of effective cooling structure there. The guide-faced nozzle elements along the mold path can be individually mounted and limit-loaded toward the belt so as to yield to local excess of outward force by the belt, for instance as caused by solidi-fied metal.

Abstract: Abstract of the Disclosure A system is provided for pumping high pressure power liquid for a downhole hydraulic pump for producing fluids from an oil well.  The power liquid is mixed in the well with the produced well fluid and is conveyed to a phase separation vessel at the surface where gas, oil and water are gravity separated.  Power liquid is withdrawn from this vessel to the inlet of a combined pitot pump and centrifugal cleaner.  This combined pump and cleaner has a stationary housing and a rotatable cleaning chamber.  A stationary pitot tube in the rotatable housing provides pressurized clean power liquid for the suction inlet of a high pressure multiplex piston pump that feeds power liquid to the downhole pump.  The rotating chamber has passages at its periphery for discharging dirty liquid which drains from the housing and is pumped to a production flow line.  Fluids from the phase separation vessel are also recovered through the production flow line.    Also, means are provided for interrupting pumping in case of excessive or deficient flow of dirty liquid from the cleaner.  Preferably the dirty liquid is pumped to the production flow line by a jet pump powered either by pressurized power liquid from the pitot tube outlet in a high pressure embodiment or by power liquid from the high pressure piston pump in a lower pressure embodiment.

Abstract: ABSTRACT OF THE INVENTION            A low cost, simple to manufacture, two axis gyro having an outer flexure assembly and an inner flexure assembly. Each flexure assembly contains two flexure hinges which represent a reduction in the number of hinges and milled cuts from those required in prior art devices.  The inner flexure assembly is designed to nest within the outer flexure assembly and both are mounted centrally on a rotatable shaft for rotation about the gyro spin axis.  The two flexures of the outer assemblies are separated 180° from each other and adjacent to two slots also separated by 180° in the rim of the outer gimbal.  Likewise, the two flexures of the inner flexure assembly are separated 180° from each other and 90° from each of the outer flexures.  The outer flexure assembly axis is offset axially by a controlled amount from the inner flexure assembly axis to achieve nominal balance on both flexure axes.
