Abstract: 1418026 Mixing apparatus BRITISH UNITED SHOE MACHINERY CO 20 March 1973 [21 March 1972] 13067/72 Heading B1C [Also in Division Fl] Apparatus for dispensing a composition e.g. polyurethane, provided by mixing together three constituents e.g. reactive hydroxyl and isocyanate compounds and colouring material comprises two single acting pumping cylinders 36, 38 actuated by an operating cylinder 64 through a rocking lever 66 pivoted at 68, and a third single acting pumping cylinder 230 actuated directly by the piston rod 84 of the operating cylinder 64; the cross-sectional areas of the cylinders 36, 38 are in inverse ratio to the distances d 1 , d 2  of their lever-connections 50, 62 from that 90 of the operating cylinder, the effect of which is that movement of the lever pivot 68 along its support 72 varies the ratio of the constituents pumped by cylinders 36, 38 but not the total quality pumped in a cycle by these cylinders nor the quantity pumped by the cylinder 230. Supply to the cylinders 36, 38, 230 from tanks 32, 34, 228 is controlled by check valves 102, 110, 245 while the discharge lines leading to a mixing chamber 10 include check valves 104, 112, 246. Supply of pressure fluid to the operating cylinder 64 is controlled by control means including a micro-switch 92 and contacts 94, 98 the latter being adjustable to vary the stroke of the operating cylinder and thus the total quantity of constituents delivered to the mixing chamber. The control means also supplies pressure fluid to a ram 20 which actuates a discharging piston 14 in the mixing chamber 10. During mixing and discharge the lever 66 is maintained in its bottom position (shown dotted at C) and to complete a cycle returns to the position A (shown dotted) which has the effect of diluting residual mixture in the mixer 10 with further ingredients. In an alternative embodiment (Fig. 2 not shown) all three pumping cylinders lie on the same side of the rocking lever so that they discharge in unison to a mixing chamber (124) which has a discharge nozzle (129) (but no stirrer of the type shown in Fig. 1). In this embodiment the cylinders discharge through solenoid-controlled twoway valves (166, 346, 186) which allow the constituents to be supplied either to the mixer or recirculated to the storage tanks. In both embodiments, Figs. 1 and 2, the pivot point of the rocking lever may lie between the lever connections of the two pumping cylinders operated by the lever in which case the operating cylinder is connected to the lever at a point outside the pumping cylinder connections.
