Abstract

1,200,507. Mixing plant; controlling. BRITISH MOTOR CORP. and BORDEN CHEMICAL CO (U.K.) Ltd. 13 Feb., 1969 [16. Feb., 1968], No. 7592/68. Heading B1C. [Also in Division B3] In a foundry core making machine, sand from; a hopper 1 is delivered to two screw mixers 5, 6 through variable aperture valves 2. Resin is fed to the mixer 5 and hardener to the mixer 6. The two mixes formed are delivered to separate hoppers ;17, 18 then to a final paddle mixer 27 simultaneously by a double slide valve 20. When the constituents of the final mixture are thoroughly blended a further valve 31 is opened to admit the mixture into a blowing chamber 40. A valve (not shown) at the base of the funnel 35 below mixer 27 closes the funnel and the final mixture is 'blown into a corebox 41. All the valves operate to a timer controlled sequence. The paddle mixer 27 is provided with compressed air jets for cleaning between mixing operations.
