Patent number: 12116210Abstract: Carriers are disclosed for supporting a plurality of agricultural cores on a plurality of core supports for coating by a flexible film. The plurality of core supports may include a pedestal for supporting a respective agricultural core and a core periphery region having a plurality of bridge elements which couple the pedestal to the connecting structure between the plurality of core supports. The carriers may include a vacuum system that independently communicates a partial vacuum to an aperture in each respective pedestal and a plurality of apertures in the core periphery region of a respective core support between the bridge elements.Type: GrantFiled: October 25, 2019Date of Patent: October 15, 2024Assignee: Corteva Agriscience LLCInventors: Scott A Adler, Marios Avgousti, Robert Ray Burch, Rajeev L Gorowara, Robert Alan Lewis, Charles A Sample, Larry D Wierschke, Jihua Zhang

Publication number: 20050234336Abstract: The present invention includes methods and materials for implantable devices (markers) which are disclosed for permanently marking the location of a biopsy or surgery for the purpose of identification. The devices are remotely delivered, preferably percutaneously. Visualization of the markers is readily accomplished using various state of the art imaging systems. Preferred visualization is through MRI, X-ray and ultrasound. The markers function to provide evidence of the location of the lesion after the procedure is complete for reference during future examinations or procedures.Type: ApplicationFiled: March 26, 2004Publication date: October 20, 2005Inventors: Andrew Beckman, Fidelis Onwumere, Michael Ludzack, Charles Samples, Ana Barbur

Patent number: 5230688Abstract: The invention has to do with the modification of well known heat sealing bag machines to increase the production capability of the machines. The use of servo drives for selected components of the bag machine permits the reduction of film acceleration and consequential peak film velocity, thus allowing faster machine cycles at the same film acceleration and consequential film velocity.Type: GrantFiled: November 1, 1989Date of Patent: July 27, 1993Assignee: FMC CorporationInventors: Peter J. Hatchell, Jeffrey L. Ross, Charles A. Sample

Patent number: 4668147Abstract: Disclosed is a rotary vacuum arm bag or sheet transferring and stacking device and a stack-handling system enabling an indexing of counted bag stacks. The transferring device grasps and retains the bags adjacent margins transverse to the direction of web advance while at least a portion of the opposed margins parallel to such direction are spaced inwardly from the arms to define a slot or gap thru which stack-retaining fingers project contributing to remove a bag from a pair of arms and retaining the bag in a stack wherein respective margins overlie each other. Also disclosed is a stack-handling system having the ability to remove a completed stack from the stacking station and yet allow, if desired, continuous bag machine operation and, as a result, uninterrupted transfer of sheets or bags to the stacking stations.Type: GrantFiled: September 22, 1986Date of Patent: May 26, 1987Assignee: FMC CorporationInventors: Charles A. Sample, Ronald L. Lotto
