20090272582 | MODULAR HYBRID DRILL BIT - An earth-boring bit comprising a bit body is cofigured at its upper end for connection into a drillstring. A fixed blade depends axially downwardly from the bit body. An axially extending slot is formed in the bit body adjacent the fixed blade. A bit leg is received and retained in the slot by engagement between the slot and correspondingly shaped bit leg, wherein the bit leg cannot be removed from the slot except by axial movement relative to the bit body. A rolling cutter is secured to the bit leg at its lower extent. A fastener secures the bit leg against movement relative to the bit body and extends through oblong apertures in the bit leg and into the bit body, wherein the bit leg can be moved axially relative to the bit body to adjust the projection of the rolling cutter relative to the fixed blade. The slot defines a pair of generally opposed sides connected by a third side, the generally opposed sides being inclined toward one another to define a dovetail that corresponds with the shape of the bit leg. The bit body further comprises a shank that is configured for connection into the drillstring at its upper extent and has a generally cylindrical receptacle formed in its lower extent; and a bit body portion having a generally cylindrical upper extent, the receptacle being and dimensioned to receive the upper extent of the bit body, wherein the shank and bit body portions are secured together by welding. | 11-05-2009 |

20090094239 | Systems and Methods for Interaction Between Employers and Professional Recruiters - An automated system with multiple databases and communication methods designed to promote the sharing and transfer of useful information and data between two parties. Specifically, the system is designed for use by employers to communicate more effectively with professional recruiters in order to dramatically increase the effectiveness of matching job candidates with job requisitions. The system creates an online virtual marketplace for employers and professional recruiters to interact and conduct all phases of the recruiting process from start to finish, and thus replaces the need for other forms for recruitment. The two primary users of this system are employers and Recruiters, but there is also some interaction with the system from other entities such as job candidates. For professional recruiters the system allows for the personal tracking, search, storage, matching, and submission of job candidate information and job candidate resumes, and the ability to search, view, track, match, and submit resumes against open job requisitions nationwide. For employers, the system provides a method to post detailed job descriptions, select recruiters to work with, determine recruiting fees, receive and process resumes, coordinate and track the interview process, schedule interviews and employment testing, and receive automated invoices for successful placements. | 04-09-2009 |
