Patent number: 10646842Abstract: A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. The blender has a plurality of material handling compartments. One or more cleaning air jets are provided in each material handling compartment. The cleaning air jets are operable to direct material towards an outlet of the compartment. Each cleaning air jet is connected to a pressurised air supply through a valve which controls delivery of pressurised air to the cleaning air jet.Type: GrantFiled: January 12, 2018Date of Patent: May 12, 2020Assignee: Vervant LimitedInventor: James Joseph O'Callaghan

Patent number: 9126352Abstract: A blender has a mixing chamber for reception of materials to be blended. A mixing screw is mounted at a bottom of the mixing chamber for mixing materials within the mixing chamber and delivering mixed materials to an outlet feeding a processing line. A baffle is mounted at the outlet extending about the mixing screw. The baffle inhibits upward movement of material at the outlet tending to cram material into the outlet.Type: GrantFiled: August 29, 2012Date of Patent: September 8, 2015Assignee: Vervant LimitedInventor: James Joseph O'Callaghan

Patent number: 7530729Abstract: A material transfer device, in particular for use with blenders associated with a material processing device such as a plastics extruding device. The material transfer device can be used for controlling delivery of measured amounts of particulate material to or from a weigh hopper, or for mixing materials in a mixing chamber of the blender. The material transfer device includes a pipe defining a material delivery path. The pipe has a material inlet and a material outlet. An air inlet manifold encircling the pipe is connected by an air supply line to a pressurized air supply. Air outlets of the manifold direct an air stream towards the outlet of the pipe to draw material through the pipe from a hopper of particulate material, the pipe inlet being located within the hopper. An air inlet valve in the air supply line is connected to a controller which is operable to open and shut the valve for pulsing the gas stream to control the amount of material delivered through the pipe.Type: GrantFiled: July 18, 2007Date of Patent: May 12, 2009Assignee: Vervant LimitedInventor: James Joseph O'Callaghan

Publication number: 20030081495Abstract: The invention relates to a material transfer device (1), in particular for use with blenders associated with a material processing device such as a plastics extruding device. The material transfer device (1) can be used for controlling delivery of measured amounts of particulate material to or from a weigh hopper, or for mixing materials in a mixing chamber of the blender. The material transfer device (1) includes a pipe (2) defining a material delivery path. The pipe (2) has a material inlet (4) and a material outlet (5). An air inlet manifold (10) encircling the pipe (2) is connected by an air supply line (14) to a pressurised air supply. Air outlets (12) of the manifold (10) direct an air stream towards the outlet (5) of the pipe (2) to draw material through the pipe (2) from a hopper (6) of particulate material (7), the pipe inlet (4) being located within the hopper (6).Type: ApplicationFiled: October 7, 2002Publication date: May 1, 2003Inventor: James Joseph O'Callaghan

Patent number: 6203184Abstract: A blender for delivery of blend additives to a plastics extrusion device has a mixing chamber for reception of materials to be blended. Batches of blend materials are delivered to the mixing chamber from material supply bins via a weight hopper. Within the mixing chamber, a mixing screw circulates and mixes the blend materials prior to discharge through an outlet to an extrusion process line. As material is discharged, a material level sensor is uncovered and calls for a further batch of blend materials to be discharged from the weigh hopper into the mixing chamber. The screw has a pair of mixing blades of opposed pitch to direct material inwardly from outer ends of the screw towards a center of the screw located above the outlet. Excess material above process demand requirements is delivered to the outlet by the screw. This excess material is directed upwardly away from the outlet and recirculated towards outer ends of the screw and remixed without material within the mixing chamber.Type: GrantFiled: June 15, 1998Date of Patent: March 20, 2001Assignee: Vervant LimitedInventor: James Joseph O'Callaghan

Patent number: 6155709Abstract: A blending apparatus has a primary additive feed hopper and secondary additive feed hoppers suspended from load cells on a support frame. Additive materials are delivered from the hoppers to a discharge chute for delivery to a material processing device such as a plastics extrusion device. A controller associated with the blending apparatus monitors the throughput of process material in the extrusion device and the discharge rate of additives from the hoppers and controls the process material throughput for controlling blending of the feed additives with the process material.Type: GrantFiled: September 11, 1996Date of Patent: December 5, 2000Assignee: Vervant LimitedInventor: James Joseph O'Callaghan
