4671919 REACTOR POWER LEVEL MONITORING SYSTEM USING AN ALPHA-BETA TRACKER Louis Gaussa, Lesley Greenberg assigned to Westinghouse Electric Corp A nuclear reactor power monitor utilizes radiation sensors, and a microprocessor implementing alpha-beta tracker equations. The use of alpha-beta tracker equations results in good noise suppression and fast follow capability. Therefore, alignment of the reactor power monitor is simplified and transients in the power level of a nuclear reactor can be detected.
4671944 PERFORATED REACTOR TUBE AND METHOD FOR FORMING A FLUID WALL IN A REACTOR Dale Schramm assigned to J M Huber Corporation A reactor tube 20 for a high-temperature fluid wall reactor has a generally cylindrical shape and is made of a refractory material which permits the tube to be heated to incandescence. The reactor tube in turn radiates energy inwardly to a reaction zone to sustain the desired hightemperature reaction. At least a length of the tube 20 is perforated to permit an inert gas to pass through the tube to form a protective fluid wall for preventing the radially-inward reactant products from contacting the inner surface 84 of the tube. Perforations 78 are located, shaped and dimensioned such that inert gas jets 86 are formed each having a substantially radiallydirected momentum sufficient to repel the reactants. The injection of inert gas is controlled so that gas jets overlap to form the protective fluid wall, but the gas jets do not disturb flow within the radially-inward reaction zone. Sections of the reactor tube may remain unperforated, but are protected by the downstream flow of the injected inert gas.
A passive infrared detector including an optical collector releasably attached to a base with a sensor on which incident infrared radiation directed through the optical collector is focused. The sensor is held by a joint member which is pivotally supported on the base and to which said optical collector is releasably attached, whereby the optical collector is rotatable together with the joint member relative to the base for adjustment of its angular position and the optical collector can be alone replaced as necessary without having to replace the base, the sensor and its associated electric circuitry.
4672690 VACUUM TANK CONSTRUCTION FOR SELF-CONTAINED SEWAGE HANDLING APPARATUS James Sigler assigned to Sealand Technology Inc A sewage treatment system includes a toilet, vacuum tank, and vacuum pump. The toilet has a discharge portion at its bottom, and a foot operated valve selectively allows, or blocks, passage of water and waste from the toilet bowl into the discharge. When the valve is opened in rushing air forces waste and water from the bowl at high velocity so that the waste fragments. The vacuum tank is connected to the toilet discharge and is disposed directly below it, and has an outlet at its bottom and a dome-shaped baffle, with side openings, covering the vacuum tank outlet. A vacuum switch is operatively connected to the vacuum tank and controls the vacuum pump. The pump is operatively connected by a conduit to the vacuum tank outlet. The vacuum tank outlet has a diameter about half the size of that of the vacuum tank iniet.
4672840 METHOD AND SYSTEM FOR DETERMINING FLUID VOLUMES OF A TWO-PHASE EFFLUENT FLUID FLOW THROUGH A POROUS MATERIAL

Alvin Cullick assigned to Mobil Oil Corporation
PASSIVE INFRARED DETECTOR
A liquid hydrocarbon and an insoluble displacing fluid are passed through a core sample from a subsurface formation. The two-phase effluent flow out of the core sample is collected in a container where the two phases separate into an

New Patents overlying fluid phase and an underlying fluid phase and the volumes of each phase are measured as an indication of the permeability of the core sample. Such volumes are measured by placing fluid level detectors in the container and detecting the movements of the air-fluid interface of the top of the overlying fluid phase and the fluid-fluid interface between the two phases as the fluid is drained from the container.

which the passages into and out of the storage container are closed, and a cap is screwed in place on the dispensing spout. Another feature is the use of the internal surface of the drain pan lid as a caddy for carrying tools for opening the oil cock and loosening the oil filter.

An extraction residue obtained by solvent deasphalting of a residual oil is mixed with a carrier gas and thermally cracked at a temperature of 400£20 + 0 C. to 600 + 20 + 0 C. in a tube-type cracking apparatus to obtain cracked oil and pitch. The use of the carrier gas, which may be either an inert gas such as nitrogen or a reactive gas such as hydrogen, permits a flow velocity through the cracking apparatus sufficient to substantially prevent coking. Preferably, the cracking conditions are controlled so that the yield of cracked oil is not more than about 30 to 35%. + RE
An automated liquid volume monitoring system and method for determining storage tank leak rate. Volume changes necessary to maintain storage tank liquid level, and volume changes due to temperature changes, are substantially constantly measured and calculations are made to determine actual leak rate. Leak rate calculations are made frequently and averaged periodically to provide updated leak rate indications for a system operator.
4673081 WASTE OIL DRAIN COLLECTOR AND STORAGE CONTAINER KIT Peter C Habig, Ronald R Daugherty assigned to Habig Peter C A waste oil drain collector and storage container kit for collecting and storing waste fluid, such as oil, drained from the engine of motor vehicles. A disclosed embodiment comprises a rectangular receptacle, which, in oil collecting position rests on a broad, flat base, supporting a drain pan in the uppermost position. A lid is designed to cover the drain pan when the receptacle is placed on end with a handle uppermost, in carrying position. A particular feature of the receptacle is a cylindrical valve which is manually rotated through three positions, a first collecting position which opens a passage from the oil drain pan to a storage container; a second pouring position which closes the passage to the storage container from the oil drain pan and opens a passage from the storage container to an external dispensing spout; and a third carrying position in
4673510 PROCESS FOR THE DISPOSAL OF SETTLED SLUDGE DERIVED FROM A BIOLOGICAL SEWAGEDISPOSAL PLANT Alois Janusch, Walte Lugscheider, Fritz Ludewig, Kindberg Aum Austrir assigned to Voest-Alpine Aktiengesellschaaft In a process for the disposal of settled sludge derived from a biological sewage-disposal plant, in which the thickened sludge is further dewatered and at least partially thermically decomposed within a centrifuge (15) by using separated steam, preferably at a pressure within the range of 1 to 15 bar and at a temperature of t00£20 + 0 C. to 200+20 + 0 C., the centrifugate of the centrifuge ( + B 15 + L ) subjected to the action of saturated steam is discharged via a lock ( + B 1 8 + L ) and is immediately subsequently subjected to a sulfidic precipitation ( + B 19 + L ) of heavy metals. The solid matter separated within the centrifuge ( + B 15 + L ) is
