20080210212 | Tools and Methods for Making and Using Tools, Blades and Methods of Making and Using Blades - Methods and apparatus for making and using tools, for example concrete cutting blades, may use laminations. They may also include inserts, such as structural inserts, damping inserts and fluid flow elements. Fluid flow elements may include a tube, a transition element including an inlet fitting, a fluid pressure containment structure inserted into the channel of the blade, an added material resistant to effects of the fluid including plastics, coatings and films, and other structures. Additional nozzle structures may be included. Methods and apparatus for making and using tools including concrete cutting blades having improved damping characteristics may include inserts, plugs and other structures, including those made from materials softer or more ductile than the tool material. Methods and apparatus for making and using tools including concrete cutting blades having improved flow directing capabilities may include inserts or other structures having vanes, foil structures, fluid diverting surfaces, baffles or other structures for affecting fluid flow in the area of the tool. | 09-04-2008 |

20110000475 | Heat reducing slot on a carbide plate and method of use thereof - A heat reducing slot that is part of a saw blade that includes tips that will house carbide or other tips that are to be attached through a torch or induction. Heat reducing slots repeat for each tip on the perimeter of a blade that will be treated with high heat. For each tip, there is a general area defined near the seat and groove of the tip. In this general area a slot is inserted that has the effect of reducing the amount of heat needed to be applied to the blade for the attachment of carbide or other tips. | 01-06-2011 |
20110262237 | Bolt on drive assembly for a core drill with high strength spoked reinforcer - A bolt on drive assembly for a core drill which utilizes an improved high strength spoked reinforcer mounted beneath a disc. The disc and high strength spoke reinforcer are removably mounted on the tube by bolt fasteners. A drive connection is removably mounted and centrally located on a outer disc of the pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The system can also include a split in the disc when the high strength spoked reinforcer is not welded thereto thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith. | 10-27-2011 |
20120176806 | CHAIN BAR APPARATUS AND METHODS - Chain bar apparatus and methods are disclosed that may be formed from plastic, metal or other materials. Laser cutting of a chain bar core can provide improved structural characteristics, for example when adhesive is used to assemble the chain bar. Flow diversion elements can be used to optimize flow throughout the chain bar. | 07-12-2012 |

20120270005 | TOOLS AND METHODS FOR MAKING AND USING TOOLS, BLADES AND METHODS OF MAKING AND USING BLADES - Methods and apparatus for making and using tools, for example concrete cutting blades. The tool includes a first layer and second layer that are oppositely disposed. The first and second layers include working surfaces that support at least one working element when the working element is applied to a work piece. Additionally, an intermediate structure is included between the first and second layers. The intermediate structure can include a plurality of components extending in the area between the structural surfaces and the working surfaces. | 10-25-2012 |
20130031793 | CHAIN BAR APPARATUS AND METHODS AND TOOL COMBINATIONS AND METHODS OF MAKING AND USING MOVING TOOL COMBINATIONS - Chain bar apparatus and methods are disclosed that may be formed from plastic, metal or other materials. Laser cutting of a chain bar core can provide improved structural characteristics, for example when adhesive is used to assemble the chain bar. Flow diversion elements can be used to optimize flow throughout the chain bar. | 02-07-2013 |
20140112728 | BOLT ON DRIVE ASSEMBLY FOR A CORE DRILL WITH HIGH STRENGTH SPOKED REINFORCER - A bolt on drive assembly for a core drill which utilizes an improved high strength spoked reinforcer mounted beneath a disc.
