FIELD: process engineering. ^ SUBSTANCE: invention relates to desk device for mixing and dispensing multicomponent compounds, particularly, dental model paste. It device extruding pushers 8a, 8b, pusher motor drive 24, variable coupling to engage pushers with motors and disengage them therefrom, at least, one manual appliance 3a, 3b to displace said pushers into disengaged position. To minimise costs, desk device variable coupling 30 incorporates helical spring 34 to engage drive side of coupling 30 with p.t.o.-side. ^ EFFECT: reduced costs. ^ 14 cl, 6 dwg |
