Title: Production of uranium peroxide
Inventor: CAROPRESO FRANK E
IPC: C22B60/02
Filed: 1976-04-21
Granted: 1980-04-29
Abstract: ABSTRACT:          A process of recovering uranium values as uranium peroxide from an aqueous uranyl solution containing dissolved vana-dium and sodium impurities by treating the uranyl solution with hydrogen peroxide in an amount sufficient to have an excess of at least 0.5 parts H2O2 per part of vanadium (V2O5) above the stoichiometric amount required to form the uranium peroxide, the hydrogen peroxide treatment being car-ried out in three sequential phases consisting of I, a pre-cipitation phase in which the hydrogen peroxide is added to the uranyl solution to precipitate the uranium peroxide and the pH of the reaction medium maintained in the range of 2.5 to 5.5 for a period of from about 1 to 60 minutes after the hydrogen peroxide addition; II, a digestion phase in which the pH of the reaction medium is maintained in the range of 3.0 to 7.0 for a period of about 5 to 180 minutes and III, a final phase in which the pH of the reaction medium is maintained in the range of 4.0 to 7.0 for a period of about 1 to 60 minutes during which time the uranium peroxide is separated from the reaction solution containing the dis-solved vanadium and sodium impurities.  The excess hydrogen peroxide is maintained during the entire treatment up until the uranium peroxide is separated from the reaction medium.

Abstract: "APPLIANCE PROGRAMMER INCLUDING A SAFETY CIRCUIT"   ABSTRACT OF THE DISCLOSURE         An appliance programmer, in particular an automatic washer programmer, employs  a memory circuit and a sequence control for establishing a predetermined program.  Included in the programmer are a safety circuit and a water level sensing circuit whose function is to detect malfunction in the filling and draining operations of the appliance.  Thus, when the machine has progressed to a washing operation during which the wash tub normally has a sufficient amount of water to perform the washing operation, the sensing circuit will sense a low water level condition and will reenergize the water fill valve solenoid to bring the water level up to the desired point.          The programmer logic permits the safety circuit to reenergize the fill valve solenoid twice in response to low water level indications after which the logic will interrupt the program in response to a third low water level indication and will deenergize the appliance.  In addition a service light is energized to call attention to the malfunction by the machine operator.  Another portion of the safety circuit interrupts the program and deenergizes the machine function and energizes a service light when water is detected in the machine tub at the end of a draining operation.

Abstract: DRIVING MECHANISM FOR DRIVING MOVING HANDRAIL          Abstract of the Disclosure The specification discloses a driving mechanism for driving a moving handrail of an escalator and the like.  The driving mechanism includes driving rollers and guiding rollers which are disposed to confront with each other with the moving handrail interposed therebetween.  The driving rollers are secured to a movable plate, while the guiding rollers are attached to fixed plates.  The movable plate is adapted to be moved in the direction perpendicular to the moving handrail, while the fixed plates are firmly secured to a part of a truss frame which supports the escalator.  The movable plate carries a sprocket by means of which the driving rollers are rotated to drive the moving handrail.  The sprocket itself is adapted to be driven by a chain or the like going therearound.  The vertical component of the tensile force residing in the chain acts to press the driving rollers onto the moving handrail to increase the frictional force between the driving rollers and the handrail.  In this way, a sufficient frictional force can be obtained when the escalator is in use, but pressure on the handrail from the driving rollers is reduced when the escalator is not in operation, thus reducing the liklihood of indentations being formed in the handrail.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides mail processing equipment which receives opened items of mail for moving these items individually past several stations. Each item is first gripped in a mail carrier which moves longitudinally and which is rotated as it moves to take up a position in which the carrier and item of mail face transversely.  Once the rotation is completed the item is released for ready removal as it passes the station.  A mail transporter is also provided to carry items of mail individually past the stations and which returns the items to these stations for a second pass in the event that the items are not removed at the first pass.  After the envelope has had the contents removed, the envelope is handled automatically in an envelope transporter but is available to the operator until such time as a further envelope is entered into the envelope transporter.  Consequently, if there is difficulty with the contents of a particular envelope, the operator can retrieve the envelope for further use. A station isolation control is also provided so that in the event that a particular station is not to receive further items of mail the control can be operated so that the transporter will not carry any more items of mail to that station.

Abstract: ABSTRACT OF THE DISCLOSURE Heat exchange takes place between two fluids, namely mineralized aqueous fluid containing dissolved or dispersed solids or mineral salts and a second fluid, in heat exchange apparatus wherein the surfaces to be contacted by the mineralized aqueous fluid are preferentially oil wettable and substantially zero water adsorbent and are continuously wetted with an organic liquid (oil) which is not permanently miscible with the aqueous fluid being treated whereby adherence of solids or mineral salts contained in the aqueous fluid or solution is prevented.  The preferentially oil wet-table and substantially zero water adsorbent contacted surfaces are preferably fluorocarbon polymers such as FEP; however, parylene surfaces are effective and substantially zero water adsorbent but are not as satisfactory as fluorocarbon polymers since parylene coatings on metal are not as permanent as FEP coatings and tend to blister under certain conditions. The apparatus and method herein described are suitable for use in the treatment of hot geothermal fluids as well as for evaporating brines.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a miniature baseball game having a board with a flat upper surface with a wall around it.          A manually operated pitching device projects miniature baseballs along the surface of the board towards a manually operated batting device.  The defensive player operates the pitching device to throw the miniature baseballs, while the offensive player operates the batting device in an attempt to hit them.  The outfield portion of the wall has a number of spaced openings through which the baseballs may be batted and while most of these are marked "strikes", some selected ones of them may be designated "balls" by the offensive player. A number of pockets are spaced along the  outfield portion of the wall, each pocket being located between two of the holes in the wall, and the pockets are marked to indicate a particular hit (single, double, etc.) when it receives a batted baseball.  However, certain ones of these pockets may be selected by the defensive player to indicate an "out" by locating an appropriate inlay in it.  Thus, some variation in the game is provided, allowing the players to influence the outcome other than merely by pitching and batting.
