Title: Apparatus for making composite plate
Inventor: SATO HIROMITSU
IPC: B29C39/18
Filed: 1985-11-05
Abstract: PURPOSE:To prevent the indents and canning of a composite plate and to decrease load against a driving wheel and a follower wheel, by inclining a top force member or a bottom force member at the neighborhood of the exit of a caterpillar type mechanism far from an area where the foaming pressure and the height of foams of a foaming material become maximum. CONSTITUTION:A bottom force member 5 is inclined in backwardly descending manner as the gap of the bottom force members 4, 5 is spread at the place far from an area where the foaming pressure and the height of foams of foaming material B become maximum. Therewith, an apparatus does not receive load by dissolving the altitudal difference at the driving wheel 7 of a mold piece 5a, also the base material A of a composite plate d is not suffered with any canning or mold mark. Thus according to the relaxation of altitudal difference of the mold piece at the exit of caterpillar type mechanism the composite plate without any indents and canning can be made. Also it is possible to decrease the load due to the change of pressure of the top force and bottom force members.

Title: Packaging method and packer
Inventor: BARIRE KURISUCHIYAN
IPC: B65B11/50
Filed: 1984-11-27
Abstract: This invention relates to a method of packing collected objects having different shapes and volumes, and to a packing station therefor. The method consists in assembling beforehand the objects to be dispatched in a container having a retractable bottom; the container is lowered towards an open-top chest covered with a plasticized film. The bottom of the container is removed so that the objects bear directly upon the plasticized film, whereafter vacuum is created in the inner volume of the chest in order to alter the shape of the plasticized film and thus lower the top level of the objects. Then the container is removed in turn and a rigid support is laid upon the objects and bonded to the plasticized film at the level of the flange of the aperture; finally, the vacuum is discontinued in the chest for releasing the package thus obtained. This invention is applicable more particularly to the mail order industry and the dispatching of goods in general.

Title: On-load tap changer
Inventor: SATO SHIGEKATSU
IPC: H01H33/28
Filed: 1986-10-22
Abstract: PURPOSE:To prevent a short circuit between taps from occurring during the operation by a method wherein a current transformer is installed at a circuit to connect a tap selector to a vacuum switch in order to unite circuits covering three phases of the current transformer into one circuit and an arrester is connected to the front so that the circuit for the current transformer can be switched in accordance with the opening and closing operation of the vacuum switch. CONSTITUTION:If an electric current is applied to a tap selector TS1 and a vacuum switch VS2 or VR2 operates normally, no electric current flows in a circuit at a tap selector TS2. If the vacuum leaks from the vacuum switch VS2 or VR2 and the withstand voltage value lowers, a leakage current flows between contacts at the vacuum switch VS2 or VR2. Then, a current transformer CT2 detects the electric current, and a voltage is generated at an arrester 15. This is recorded by a measuring instrument 16, and a control device 17 sends an instruction of whether the changeover of the tap must be continued or must be stopped immediately. When one tap is changed over and an electric current flows at the tap selector TS2, the tap changer 16 is switched mechanically to the tap selector TS1, and detects the leakage of a vacuum at the vacuum switch VS1 and VR1.
