Patent number: 10216156Abstract: A header assembly for a combine harvester includes a header carried by an adapter on the feeder house of the combine controlling an angle of the header defined by a tilt cylinder and height of the header at the feeder house. Wings of the header are carried on gauge wheels the height of which relative to the header frame can be adjusted by cylinders. A driver interface inside the cab includes inputs to be set by the driver of cutter bar height and header angle.

Patent number: 8863483Abstract: A swather tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. There is provided a float module with adjustable and calibrated springs connected between a mounting assembly on the tractor and pivotal support arms of the float assembly where the mounting assembly can be raised and lowered by a lift system on the tractor. This allows the header to float relative to the lift system on the tractor. The float force of the springs is adjusted by raising and lowering the lift system in dependence on an angle measurement of the lift position of the header as it floats relative to the mounting assembly.Type: GrantFiled: November 16, 2012Date of Patent: October 21, 2014Assignee: MacDon Industries Ltd.Inventors: Roger L. Patterson, Andrew William Dean Bell, John Edward Enns

Patent number: 7218046Abstract: A method of making a unitized tungsten electrode which exhibits superior mechanical and electrical properties which includes providing a length of cylindrical cut stock having a predetermined diameter and length. The stock is ground to form a rough unfinished electrode having an enlarged tip or nose portion at one end integrally connected to an elongated shank section. The unfinished electrode is treated by exposure to a chemical etchant for a time sufficient to form a finished electrode characterized by a smooth nose and shank surface and rounded undercut and ends. The invention includes the electrode formed by the described process.Type: GrantFiled: August 3, 2006Date of Patent: May 15, 2007Assignee: Welch Allyn, Inc.Inventors: Dean A. Bell, Timothy D. Russell
