Abstract

<PICT:0826623/III/1> A mixing head e.g. for mixing the components of a synthetic resin in liquid form, consists of a pre-mixing chamber into which the liquid components are fed in counter current and impinge to form a mixture which is then led to a two-compartment chamber, the second of which is larger in cross-section than the first to induce turbulence. Air under pressure may be injected into the second chamber. The main component e.g. a polyester is fed by a pump through a flexible pipe 1 to a passage 2 of a nozzle element 3. The secondary component consisting of polyisocyanate, is fed through a flexible pipe 7 preferably in pulses, and is sprayed against the continuous stream of the main component of a polymethane rising into a passage 6. The mixture flows through a channel 8, supply passage 9 and bores or slots 11 into a turbulence chamber 12 from which it passes to outlet 14. In a modification, the turbulence chamber is fed with compressed air to promote mixing. Specifications 769,680, [Group IV (a)], and 769,682 also are referred to.
