Abstract

974, 558. Proportioning by weight. C. PASQUALE, and A. PASQUALE, [trading as R. C. M. REVISIONE CONSTRUZIONE MACCHINE]. Oct. 7, 1963 [Nov. 17, 1962], No. 39459/63. Heading G1W. [Also in Division B1] An apparatus for preparing a water-asbestos cement slurry in desired proportions by weight comprises a mixer tank 1 suspended from a weigh beam 22 fulcrummed at 23 which indirectly automatically controls the proportions and also the steps in the automatic operative cycle. In operation water is fed to the tank first via conduit 7 valve 8, and opening 4 and is given a swirling motion by being circulated in a closed system and fed into the tank again tangentially by a pump 9. The closed circuit includes tank 1, suction pipe 11, delivery pipes 12, 13, the valve 15 being open and valve 16 closed. The necessary water quantity is preset by adjustment of counterweight 24, such that when the required quantity has been fed the end of the beam coincides with a gauge 25. A photo-electric cell (not shown) incorporated therein sends a pulse which stops the water feed and by means not disclosed iniates the delivery of asbestos fibres to the tank through an opening 5. The asbestos fibres are dispersed by the swirling motion and also by an impeller of the pump. A dial indicator 27 is connected to one end of the weigh beam and its pointer 28 indicates zero at the initiation of the asbestos feed. A pointer 29 is set at a value representing the desired weight of asbestos and when pointer 28 coincides with pointer 29, the photo-electric cell emits a pulse whereby the asbestos feed is stopped and the feed of cement is initiated through an opening 6. This feed continues until the pointer 28 reaches a further pointer 30 which is set at the value representing the desired weight of cement, and by photo-electric signal means the cement feed is stopped. The slurry is further mixed for a period controlled by a timer (not shown) and then the valve 15 is closed and valve 16 is opened whereby the slurry is pumped through a pipe 14 to a utilizing plant (not described). The valves 8, 15,16 are electropneumatically actuated.
