Patents by Inventor Susan B. Filardo

Susan B. Filardo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6601708
    Abstract: A process and apparatus for processing polyvinylacetate and other similar ingredients of a gum base or chewing gum product are disclosed. The ingredient materials are separated into individual pieces by a lump breaker and conveyed through a pneumatic conveying system to a cyclone receiver and holding bin. A volumetric feeder feeds the material into a side feeder which in turn introduces and feeds the material to the main continuous extruder used for making the final gum base or gum product. A unique adapter connects the side feeder to the main extruder which allows repair and/or modification of the side feeder without separating it from the main extruder.
    Type: Grant
    Filed: July 25, 2000
    Date of Patent: August 5, 2003
    Assignee: Warner Lambert Company

  • Patent number: 6056429
    Abstract: A process and apparatus for melting and processing a high molecular weight elastomeric material for a gum base or chewing gum product is disclosed. The solid elastomeric material, which preferably is polyisobutylene, is heated and melted into a liquid material which is then transported to an extruder. The apparatus has a heated housing section which includes sets of heated plate members arranged in fan-type groupings. Heated diverter members are positioned beneath the sets of fan-type plates. A heated angled conduit section is positioned below the housing section and a heated storage section is attached to the angled conveyance section. A valve and pump system is used to discharge the liquid elastomeric material from the holding section to the gum base or chewing gum extruder. Accurate metering and feeding of the liquified elastomeric material to a continuous extrusion process is achieved.
