Abstract: PURPOSE:To provide simplification of the control for driving a moving die, etc. by providing a hydraulic cylinder for pressurization between plural nuts and the lower die and driving the respective screw bars screwed to the nuts by a motor via a gear train. CONSTITUTION:The plural nuts 30 are screwed respectively to the screw bars 29. A press-contact cylinder 31 is disposed between the nuts 30 and a moving table 4. The screw bars 29 are driven via gears 27, 28 and the nuts 30 move upward when the motor 26 is driven. Since the 2nd gear 28 is meshed with the 3rd gear 35 via a counter gear 36 in this stage, all the bars 29 are turned and the table 4 moves upward and uniformly. The motor 26 is stopped and the cylinder 31 is operated to pressurize a material to be worked on approaching of the die 6 to the die 5. The smaller stroke of the cylinder 31 is necessitated by this method and the control for driving the moving die 6 by the bars 29 is made simple.

Title: Bacteria-carrier for sewage disposal
Inventor: KAYABA JIYUN
IPC: C02F3/08
Filed: 1980-08-01
Abstract: PURPOSE: To obtain a carrier having a large surface area, a good adhesiveness and a small specific gravity, useful as a bacteria-carrier for sewage disposal, by using a foam prepared by adding an additive and a foaming agent to a synthetic resin material and then expanding the mixture into a granular shape.  
     CONSTITUTION: An additive, e.g. calcium carbonate, and a foaming agent are added to a synthetic resin material, e.g. polyethylene or polypropylene, and the mixture is expanded. When the expanded mixture is formed into a granular shape, a lot of ruggedness is formed in the interior and the surface of the obtained particle. The product is used as a bateria-carrier for sewage disposal. The carrier has a large surface area per weight, and bacteria well adhere to and are scarcely detached from the carrier. Besides, the carrier has a specific gravity smaller than that of water, so that the carrier floats in sewage and acts as an effective carrier.

When a fixed current is carried with a uranium recovery negative electrode 6 as negative, and the positive electrode 2 serving as the basket, as positive, only uranium is precipitated on the negative electrode 6 to obtain uranium of high purity. Pu remains in the positive electrode 2 serving as the basket, and recovered.  Noble metal is precipitated on an auxiliary negative electrode 7 together with a small quantity of uranium without being mixed in uranium and plutonium recovered by the negative electrode 6. Minor actinides are dissolved in the molten salt.
