Patent number: 9951481Abstract: A dowel placement system including a fastener configured to be engageable with a form, and a radially compressible bushing coupled to the fastener and defining an adjustable outer diameter. The system further includes an elongate dowel sleeve having opposed proximal and distal end portions, and an axial opening having an inner diameter and extending into the dowel sleeve from the proximal end portion to the distal end portion. The bushing is insertable within the axial opening of the dowel sleeve, and the bushing and dowel sleeve are configured such that insertion of the bushing within the dowel sleeve causes the outer diameter of the bushing to compress and conform to the inner diameter of the dowel sleeve and to create a friction force between the bushing and the dowel sleeve to mitigate movement of the dowel sleeve relative to the bushing during formation of the concrete structure.Type: GrantFiled: March 3, 2017Date of Patent: April 24, 2018Assignee: Shaw & Sons, Inc.Inventor: Ronald D.

Patent number: 9930823Abstract: A system for reducing implement wheel forces on a field surface has an agricultural implement with a frame mounted on frame wheels and ground engaging tools mounted on the frame. When the ground engaging tools move down to penetrate the field surface they exert an upward tool force on the frame. Support arms are movably connected to the implement frame and a support wheel is rotatably mounted to each support arm. A support bias element exerts a support bias force on each support arm to force the support wheel against the field surface and to correspondingly force the implement frame upward, transferring a supported frame weight from the implement frame to the support wheels, such that an unsupported frame weight is carried on the frame wheels. A bias control varies the support bias forces to maintain the unsupported frame weight at a level greater than the upward tool force.Type: GrantFiled: November 21, 2014Date of Patent: April 3, 2018Assignee: Bourgault Industries Ltd.Inventors: Scot Jagow, Robert Klenz, Aden Arguin
