Title: Disc valve
Inventor: SCARAMUCCI DOMER
IPC: F16K1/226
Filed: 1979-09-05
Granted: 1981-02-24
Abstract: Abstract of the Disclosure A pressure actuated seat ring for a disc valve has a tubular, relatively flexible portion extending axially from a radially thicker, relatively inflexible portion.  The flexible portion of the seat ring extends circumferentially about the disc of the valve when the valve is closed and a cavity is formed about the flexible portion such that fluid pressure in the cavity tends to force the flexible portion of the seat ring against the disc.  The ends of the cavity are vented to the flow passage of the valve at opposite sides of the disc and an elastomeric sealing ring mounted on the tubular por-tion of the seat ring is movable within the cavity in response to a pressure differential at the vents to seal the vent ex-posed to the lower pressure so that the larger pressure is transmitted to the cavity.

Abstract: Case No. 108.151A     IMPROVED CYCLICAL CENTRIFUGAL MACHINE                 ABSTRACT OF THE DISCLOSURE              An improved cyclical centrifugal machine includes a rigid support mounted above the basket of the machine, a bearing housing suspended from the support for gyratory motion, a basket-carrying spindle rotatable in fixed position relative to the housing on bearings therein and an electric motor for bringing the spindle and basket to rotational speed.  The improved centrifugal machine also comprises a system for controlling transmission of torque from the motor to the basket by means of a clutch having relatively rotatable clutch members adapted to trans-mit torque through liquid films between them.  The clutch is operated to vary the torque transmitted from the motor to the basket so as to produce a maximum load to be placed on the motor for producing a desired basket speed. To so operate the clutch, signals proportionate respectively to the instantaneous load on the motor and the instantaneous speed of the basket, and reference signals representing respectively the maximum load to be placed on the motor and the desired operating speed, are compared to produce from them a resultant signal representing the instantaneous relationship of the actual load on the motor to the maximum load.  The clutch is then operated to vary the torque trans-mitted through the liquid films between the clutch members in response to the resultant signal to produce the maximum load.

Title: Solar heating system
Inventor: SIERADSKI LEONARD M JR
IPC: F24S10/80
Filed: 1980-03-16
Granted: 1986-12-16
Abstract: Abstract of the Disclosure A self-cooling solar forced air heating collector module, and method of constructing a plurality of the same in modularized array from standarized components, for a solar heating system.  The collector has an inner heating compartment beneath an inner glazing, and an outer heating compartment between the inner glazing and an outer glazing.  A forced air inlet duct enters the collector bottom surface and communicates directly only with the outer compartment at a given location longitudinally of the collector.  An always-open passage effects air flow communication from the outer to the inner compartment, at one longitudinal end thereof re-mote from the inlet duct.  A sole outlet duct extends through the bottom surface and communicates directly only with said inner compartment in the vicinity of the inlet duct.  A black body absorber comprising an air-permeable single layer screen extends within the inner compartment such that the forced air flows along and in the same direction on both sides of the screen.  The collector is oriented in operation for solar inci-dence transverse to the glazings with its lengthwise dimension horizontal and its width dimension tilted at an angle between 10° through 90° from horizontal.  Upon cessation of forced air flow via the ducts, whereupon a stagnation condition occurs in the collector, the air trapped therein automatically circulates within the collector and to and from the com-partments via the always-open passage in response to solar-incidence-induced convection currents, thereby producing a self-cooling action.

Abstract: FLOTATION METHOD AND APPARATUS FOR RECOVERING CRUDE OIL FROM TAR-SAND          ABSTRACT OF THE DISCLOSURE       This invention relates to an improved method and apparatus for scrubbing crude oil (bitumen) from tar-sands, the apparatus being characterized by a heated vessel for maintaining the tar-sand/water slurry at between approximately 180-200°F., a pair of counterrotating screw conveyors in the bottom of the vessel for agitating the sand and moving it to the discharge end, means for simultaneously diluting and aerating the incoming slurry that produces small bubbles effective to float the crude oil freed from the sand to the surface, an overflow wier running alongside the vessel for catching the oil skimmed off the surface of the water, transversely-extending endless chain-and-flight skimmers for skimmming the oil into the wier, a bottom-opening discharge for the clean sand, and valves controlling the discharge of sand effective to remove the latter without lowering the fluid level in the vessel to a point where the oil previously released can reattach itself to the sand. The method encompasses the steps of submerging the tar-sand in the vessel to a point where the oil previously released can reattach itself to the sand. The method encompasses the steps of submerging the tar-sand in a hot water bath, agitating the sand while thus immersed while continuously bubbling air up through the slurry to float the oil particles freed from the sand grains to the surface, continuously skimming off the oil floating on the water bath from the surface thereof, and withdrawing the clean sand from the bottom of the vessel intermittently and quickly enough to prevent the level of the water bath from falling below the top of the screws.

Abstract: 22,136 Abstract of the Disclosure Method and apparatus for general illumination wherein high frequency power is capacitively coupled to a low pressure discharge.  A discharge lamp includes an envelope which is typically pear-shaped with a re-entrant cavity. The lamp envelope encloses a fill material which forms during discharge a plasma which emits ultraviolet radia-tion and has an effective electrical impedance.  The lamp envelope typically includes on its inner surface a phos-phor coating.  An outer conductor, typically a conductive mesh, is disposed around the outer surface of the lamp envelope.  A solid or hollow inner conductor is disposed in the re-entrant cavity.  The apparatus is configured so that the capacitive impedance associated with coupling of high frequency power from the conductors to the discharge is much less than the plasma impedance.  Low capacitive impedance is achieved by utilizing high frequencies and conductors with large surface areas and by maintaining the conductors in close contact with the lamp envelope.  Sub-stantially all of the induced electric field is confined within the discharge lamp.  The inner conductor can have a shiny surface which is operative to reflect emitted light back to and through the discharge lamp.  A high frequency power source can be included in the apparatus.

Granted: 1984-01-17
Abstract: ABSTRACT OF THE INVENTION Brain wave patterns associated with relaxed and meditative states in a subject are gradually induced without deleterious chemical or neurological side effects. A white noise generator (11) has the spectral noise density of its output signal modulated in a manner similar to the brain wave patterns by a switching transistor (18) within a spectrum modulator (12).  The modulated white noise signal is amplified by output amplifier (13) and converted to an audio signal by acoustic transducer (14).  Ramp generator (15) gradually increases the voltage received by and resultant output frequency of voltage controlled oscillator (17) whereby switching transistor (18) periodically shunts the high frequency components of the white noise signal to ground.

Abstract: A process and apparatus for manufacturing cement clinker in which pellets of raw material containing the necessary components for manufacturing the clinker are introduced into an apparatus where the pellets flow under gravity, successively through a preheating zone, a clinkering zone using a fluidized bed and a cooling zone. The pellets contain an amount of comminuted carbon determined so that its combustion produces an amount of heat within each pellet sufficient to carry out decarbonation of the material, taking into account the heat introduced by the hot gases passing upwardly through the apparatus. Decarbonation is completed at the base of the preheating zone and the pellets enter the clinkering zone at a temperature which is close to the clinkering temperature. Additional heat is supplied through burners within the clinkering zone.
