Patent number: 10947969Abstract: High pressure injection apparatus (2) for addition of a liquid formulation into a melt stream comprises a first pump which is arranged to accurately meter the liquid formulation (including highly loaded formulations comprising solids comprising particles of relatively large size) and a second pump which boosts the pressure of the formulation to that of the melt stream into which it is to be injected. In an embodiment, the apparatus includes a tank (4) for initially receiving liquid formulation. The tank is subjected to ambient temperature and pressure and need not be stirred or otherwise agitated. The tank is arranged to deliver the formulation via pipe (6) into a first pump (8) (which may be a diaphragm pump or a progressing cavity pump). The pump is arranged to work at a pressure up to 120 bar to boost pressure. Downstream of pump (8), a pipe (10) is arranged to deliver formulation from the pump (8) to a gear pump (12), driven by a motor (13). The gear pump acts to meter the liquid formulation.Type: GrantFiled: June 26, 2014Date of Patent: March 16, 2021Assignee: ColorMatrix Europe LimitedInventors: Andrew Overend, Ian Campbell, Brian Jones

Publication number: 20210053253Abstract: Polymeric Materials An injector (14) for injecting liquid formulation into molten polymer includes a conduit (117) having regions (44, 46) which are secured within a wall of an extruder (19). Conduit (117) includes an annular collar (120) having an upwardly facing annular surface (122) which is arranged to bear against part of a sleeve nut (124). Conduit (117) is arranged within a port (125) which includes a screw-threaded wall (126). The sleeve nut (124) includes a cylindrical body (146) having an inwardly facing cylindrical wall which is arranged to define a cylindrical air gap (148) between itself and an outer wall (147) of conduit (117). Region (150) of the sleeve nut is screw-threadedly engaged in wall (126) of the extruder. In use, cool compressed air is introduced into the assembly in the direction of arrow (170) and it flows through the assembly to cool it.Type: ApplicationFiled: February 28, 2019Publication date: February 25, 2021Inventors: Brian JONES, David WHITEHEAD, Ian CAMPBELL, David LOFTUS, Andrew OVEREND
