Patent number: 11548107Abstract: Methods of inducing segmented flow in a material in which a ductile flow mode would otherwise occur during machining. A monolayer molecular film is formed on a surface of a body of a material in a state such that the material exhibits ductile flow when subjected to shear. The monolayer molecular film has molecules each having a head group adsorbed to the surface, a terminal group, and a hydrocarbon chain therebetween having a chain length of greater than 6. A surface portion of the body is removed by engaging the body with a tool in a contact region below the surface of the body and moving the tool relative to the body to remove the surface portion and the monolayer molecular film thereon. The monolayer molecular film induces segmented flow in the material during the removing of the surface portion.Type: GrantFiled: November 6, 2020Date of Patent: January 10, 2023Assignee: Purdue Research FoundationInventors: Tatsuya Sugihara, Srinivasan Chandrasekar, Anirudh Udupa, Koushik Viswanathan, Kevin Paul Trumble, James Bradley Mann

Patent number: 9863445Abstract: A fluid reservoir comprises a first compartment, a second compartment, a port, a drain, and a tube. The port is fluidly connected to the first compartment and positioned at a port height. The drain is fluidly connected to the first compartment and the second compartment. An entrance to the drain is positioned in the first compartment at a drain entrance height which is lower than the port height. The tube is fluidly connected to the first compartment and the second compartment. An entrance to the tube is positioned in the first compartment at a tube entrance height which is higher than the drain height.Type: GrantFiled: April 22, 2014Date of Patent: January 9, 2018Assignee: DEERE & COMPANYInventors: Micheal E. Barr, Brian K. Kellogg, Bradley A. Mann

Patent number: 9687895Abstract: Processes by which bulk forms can be produced in a single continuous operation, as opposed to multi-stage deformation processes that involve a series of separate and discrete deformation operations or stages. Such processes generally entail deforming a solid body using a large-strain extrusion machining technique and deformation conditions that obtain a predetermined crystallographic texture in the continuous bulk form that differs from the crystallographic texture of the solid body.Type: GrantFiled: January 6, 2012Date of Patent: June 27, 2017Assignee: Purdue Research FoundationInventors: Srinivasan Chandrasekar, Kevin Trumble, Wilfredo Moscoso, Mert Efe, Dinakar Sagapuram, Christopher J. Saldana, James Bradley Mann, Walter Dale Compton

Patent number: 9527134Abstract: Methods suitable for producing textured surfaces in surfaces of objects, by which the methods are able to achieve a desired three-dimensional surface topography and optionally a desired subsurface microstructure through the use of a controlled modulation machining technique. The methods include selecting a predetermined surface texture for a surface of a body, and then imposing a superimposed sinusoidal feed-modulation on a cutting tool so as to move the cutting tool in a feed direction relative to the body while machining the body with the cutting tool and generating a machined surface of the body. The surface texture of the machined surface is intentionally controlled by at least the modulation amplitude and the modulation frequency of the superimposed sinusoidal feed-modulation.Type: GrantFiled: March 30, 2012Date of Patent: December 27, 2016Assignee: Purdue Research FoundationInventors: James Bradley Mann, Srinivasan Chandrasekar, Christopher Javellana Saldana, Yang Guo, Walter Dale Compton

Patent number: 6397518Abstract: The present invention provides a pipe system for termite-proofing a sub-floor area of a structure having a foundation penetrated by at least one penetration comprising: (a) a primary tube system comprising tube(s) located substantially at or adjacent the perimeter of the building; (b) a secondary tube system comprising tube(s) adjacent at least one penetration; and (c) means for charging both primary and secondary tube system with insecticide. The tube systems comprise tubes perforated along a substantial portion of their length by a plurality of apertures of such size and spacing that insecticide flows through the apertures and infuses the adjacent ground. The penetrations may take the form of plumbing pipelines or load bearing members for a suspended slab or floor.Type: GrantFiled: December 15, 1999Date of Patent: June 4, 2002Assignee: Termguard Pty Ltd.Inventor: Bradley Mann
