Title: Preparation of pinacolone
Inventor: TAMURA MITSUHISA
IPC: C07C49/04
Filed: 1981-02-27
Abstract: PURPOSE: To improve the yield with a small amount of an acid without using an expensive catalyst in rearranging pinacol to pinacolone through dehydration, by rapidly distilling off water formed with the progress of the reaction with the formed pinacolone, etc. to the outside of the reaction system.  
     CONSTITUTION: In synthesizing pinacolone from pinacol by the liquid-phase acidic catalytic reaction, the pinacol is continuously or intermittently introduced into and brought into contact with a heated reactor containing an acidic catalyst, e.g. sulfuric acid or p-toluenesulfonic acid. Water formed with the progress of the reaction is rapidly distilled off with the formed pinacolone in the form of an azeotropic mixture to the outside of the reaction system. Preferably, the pinacol as a solution in a solvent, capable of forming the azeotropic mixture with water, e.g. benzene, is introduced into the reaction system, and the water formed with the progress of the reaction is distilled off with the solvent in the azeotropic mixture to the outside of the system. The amount of the acid as a catalyst is 0.5W10mol% based on the pinacol.

Title: Parallel conveyance copying machine
Inventor: HIRONO TATSUO
IPC: G03G21/00
Filed: 1985-02-19
Abstract: PURPOSE:To increase a copying speed while holding the processing speed of image formation constant by copying different-mode originals by the same copying operation during parallel conveyance. CONSTITUTION:The parallel conveyance allows copying operation in which an original of large size is copied to two sheets of small size as it is known as continuous page copying, but originals of different kind (different mode) can be copied by the same copying operation. Namely, modes (copy quantity, both-surface, composition, and inversion) are settable for originals A and B which are copied by the same copying operation respectively and the number of times of repetition is specified by a larger copy quantity setting side in the copying operation. In such a case, a photosensitive body is erased in copying operation after copies are taken by a set number at a smaller quantity setting side to eliminate unnecessary development. Consequently, various copy modes are dealt with an the copying operativity is improved.

Title: Method and tank for preventing sedimentation of solid matter of slurry
Inventor: OMURA TAKASHIGE
IPC: C10L1/32
Filed: 1994-02-28
Abstract: PURPOSE:To prevent the sedimentation of a solid matter of a slurry (e.g. CWM. an aq. slurry of fine coal powder) in a tank by floating a float equipped with a suction port on the surface of the slurry, installing a push-out port near at the bottom of the tank, and circulating the slurry by sucking the slurry having a low concn. at the upper part through the suction port and pushing out the low-concn. slurry through the push-out port. CONSTITUTION:The sedimentation of a solid matter of a slurry (e.g. CWM) in a tank is prevented by floating a float 2 equipped with a suction port 3 on the surface of the slurry and pushing out the slurry having a low concn. at the upper part through a push-out port 4 installed near at the bottom of the tank to circulate the slurry. The circulation is done with a flexible hose 6A, an internal or external pump, and piping depending on the size and shape of the tank. The flow of the slurry in the tank prevents the sedimentation of the solid matter. A rail 7 and a traveling truck 8 are installed depending on the shape of the tank (e.g. a tank with a rectangular section) to move the pump and the push-out port to desired positions. This method wears the apparatus little, requires little driving energy, and facilitates the maintenance of the apparatus.

Title: Platinum alloy for accessory

Filed: 1981-03-03
Abstract: PURPOSE: To obtain a Pt alloy for an accessory with superior mechanical  strength and workability by preparing an alloy consisting of specified amounts  of Pt and Ga.  
     CONSTITUTION: The composition of a Pt alloy for an accessory is composed of 92W97.5w/o Pt and 2.5W8w/o Ga. The reason for the addition of Ga is that Ga shows remarkable age hardenability by aging at a suitable temp. after soln. heat treatment by heating to the solid soln. range and quenching, yet <2.5w/o Ga improves hardly the hardness, and >8w/o Ga increases the amount of intermetallic Pt-Ga compound and deteriorates the workability.
