Abstract
986,369. Hydraulic jacks. BETEILIGUNGSUND PATENTVERWALTUNGSGESELLSCHAFT. Nov. 22, 1963 [Nov. 24, 1962], No. 46255/63. Heading F1P. [Also in Division F4] In a bell-and-hopper charging device for a blast furnace where the bells 1 and 2 are actuated respectively by pistons 6 and 5 in hydraulic cylinders, non-return valves being incorporated in each pressure line 7, a small reservoir 9 disposed between each valve 8 and its associated cylinder has an air cushion in its upper part. This helps to prevent opening of the bells when valves 8 are closed by compensating for pressure losses due to leakage. The air cushion may be replaced by a piston resting on the pressure fluid, the rod of which extends out of the reservoir and carries an external weight.
