Title: Method of producing high purity zirconia powder from zircon powder
Inventor: FUNAHASHI TOSHIHIKO
IPC: C01G25/02
Filed: 1985-04-02
Granted: 1991-05-28
Abstract: ABSTRACT OF THE DISCLOSURE          In producing zirconia powder by desiliconizing heat treatment  of  a mixture  of  zircon powder  and a powdery  carbon-containing  material,  optionally  with addition of a zirconia stabilizing oxide such as calcia or  yttria,  in  a  non-oxidizing  atmosphere,  the  heat treatment is performed under reduced pressure, viz. at a pressure hot higher than 0.7 atm, to thereby efficiently gasify silicon oxide in reduced form.  To obtain very pure zirconia powder, adjustment of C/SiO2 mole ratio in the starting mixture to 0.4-2.0 and oxidation treatment of the product of the reduced pressure desiliconizing heat treatment are effective. Fluidization of at least a portion of the carbon-containing material at the stage of  mixing with  zircon powder  is  also  effective  for decreasing residual silica in the product.

Title: Paging receiver with a capability of receiving message data
Inventor: MORI TOSHIHIRO
IPC: G08B3/10

Granted: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE A paging receiver having a capability of receiving message data includes a data set and hold circuit the output logic of which is inverted in response to the detection of a control signal which follows a Paging number assigned to that receiver. The receiver is excluded from or restored into a data service which is allowed by a common number adapted for many and unspecified receivers, by the output of the data set and hold circuit. The data set and hold circuit is powered by a different power source from a main power source of the receiver. Whether or not the power source associated with the data set and hold circuit is present is determined and, if it is not present, receipt of the data service based on the common number is inhibited. To eliminate malfunctions due to static electricity, a train of pulses are used as a control signal which follows a paging signal assigned to the individual receiver. The data set and hold circuit responds to means for sensing the pulse train, whereby the receipt of the data service which is based on the common number is inhibited or recovered by an output of the data set and hold circuit.

Title: Coal agglomeration beneficiation with heavy hydrocarbon oils and utilization thereof in coal/heavy oil coprocessing
Inventor: IKURA MICHIO
IPC: C10G1/00
Filed: 1987-07-14
Granted: 1991-01-15
Abstract: Abstract An improved process is described for agglomeration beneficiation of ground coal in which undiluted heavy oil or bitumen is used as the agglomerating vehicle.  The ground coal, water and heavy oil or bitumen are mixed at an elevated temperature sufficient to lower the viscosity of the heavy oil or bitumen to a level permitting easy mixing and at an elevated pressure sufficiently high to prevent boiling of the water.  This mixing causes agglo-meration of the carbonaceous solids with the heavy oil or bitumen and the agglomerates obtained are separated from the tailings containing aqueous medium and inorganic solids.  The separated agglomerates are preferably used with additional heavy oil or bitumen to form a slurry feedstock for a coprocessing unit.  This provides a very efficient total process since the coal agglomeration beneficiation uses a portion of the same heavy oil or bitumen feedstock which is used for coprocessing and no additional hydrocarbon diluent is required.

Title: Retention apparatus for retaining an object in a predetermined position
Inventor: ADAMS KIRK D
IPC: H05K7/14
Filed: 1987-09-24
Granted: 1991-04-16
Abstract: A B S T R A C T            Retention apparatus for retaining an object in a predetermined position This retention apparatus seats and holds an object in place with a constantly applied force.  In the preferred embodiments the device has two resilient bow-shaped elongated members that outwardly extend on opposite sides of a handle. Actuating the handle in a linear direction causes the object to move in the same direction to the desired location, carrying the resilient members as it does so.  At the desired location, the movement of the object is stopped, but further travel of the handle in the same direction is accomplished by deflection of the resilient bow-shaped members which in turn provides the constantly applied biasing force to the object to seat and hold it in place. An embodiment is described for a retention apparatus to seat and hold a double sided printed circuit card in a pair of zero insertion force type edge connectors.  In another embodiment, the device seats and holds two mating connector members, such as a receptacle and header which have mating terminals and pins.

Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method for the production of storable preservative-free fruit preparation containing whole fruit, by mixing freely rolling fruit with crystalline sugar or highly concentrated sugar solution and making the mixture of fruit and juice subsequently thermally keepable. After gentle juice formation, the fruit is separated from juice, the juice is at least approximately adjusted to the thickness of the fruit and then recombined therewith. The mixture is subsequently briefly heated by a microwave field, excited in an E01 mode,  in a heating zone.  The method is particularly suitable for fruit preparations made from white fruit, the properties of which remain unchanged. The fruit preparations obtained in this way can be used alone or as an ingredient of food products, for example yogurt, cottage cheese or desserts.
