Patent number: 9856875Abstract: Air compressor systems, upgrade kits, computer readable medium, and methods for controlling an air compressor for improved performance. The methods may include receiving a working air requirement; determining an estimated air pressure of the air compressor to deliver the working air requirement; measuring a pressure of the air compressor; comparing the measured pressure with the calculated estimated air pressure; if the measured pressure of the air compressor is greater than the determined estimated air pressure by a predetermined greater amount, then decreasing an output control of the air compressor; and if the measured pressure of the air compressor is less than the calculated estimated air pressure by a predetermined lesser amount then increasing the output control of the air compressor. The air compressor may be controlled based on a measured pressure of delivered working air. An oil control system may shut off oil to parts of the air compressor.Type: GrantFiled: April 12, 2016Date of Patent: January 2, 2018Assignee: Sandvik Intellectual Property ABInventors: Grant Andrew Field, Simo Tanner, Karl Ingmarsson

Patent number: 6276467Abstract: A percussive rock drill bit includes a steel bit body and carbide button inserts mounted in a front cutting face thereof. The bit body includes a passage intersecting the front cutting face for conducting a flushing/cooling medium to the front cutting face. The flushing/cooling medium travels to an outer periphery of the bit body and travels upwardly within flushing grooves formed in the outer periphery of the bit body. Portions of the bit body situated between successive ones of the flushing grooves constitute wings of the bit body. Some of the button inserts constitute gauge inserts. Only a gauge insert is mounted in each wing. At least some, possibly all, of the gauge inserts are offset circumferentially from a center of the respective wing toward a trailing end of the wing.Type: GrantFiled: October 25, 1999Date of Patent: August 21, 2001Assignee: Driltech Mission LLCInventor: Karl Ingmarsson

Patent number: 6105693Abstract: The present invention relates to a partially enhanced drill bit (10') for percussive drilling. The bit comprises a bit body, at least one annular row of non-enhanced buttons (11') mounted in the bit body; and at least one annular row of enhanced buttons (12') mounted in the bit body radially outside of the non-enhanced buttons. At least one annular row of non-enhanced buttons (11') and said at least one annular row of enhanced buttons (12') are provided to partly overlap each other. There is an axial shoulder (19') radially outside of the non-enhanced buttons (11'). There are chamfers (20') at least partly surrounding the enhanced buttons (12'). These chamfers (20') interrupt the shoulder (19') in the circumferential direction.Type: GrantFiled: February 18, 1999Date of Patent: August 22, 2000Assignee: Sandvik ABInventor: Karl Ingmarsson

Patent number: 6073711Abstract: A partially diamond-enhanced drill bit includes a bit body, at least one annular row of non-diamond enhanced buttons mounted in the bit body, and at least one annular row of diamond-enhanced buttons mounted in the bit body radially outside of the non-enhanced buttons. A total wear volume of the non-enhanced buttons in at least one row thereof is greater than 75 percent of a total wear volume of an outermost annular row of enhanced buttons. A number of non-enhanced buttons in one of the rows thereof is at least equal to a number of enhanced buttons in the outermost annular row thereof. At least some of the non-enhanced buttons have a greater wear volume than any of the enhanced buttons. The radially outermost row of non-enhanced buttons is displaced axially forwardly with respect to an adjacent row of enhanced buttons.Type: GrantFiled: August 18, 1997Date of Patent: June 13, 2000Assignee: Sandvik ABInventor: Karl Ingmarsson

Patent number: 5950745Abstract: A button insert for a percussive drill bit comprises a carbide base and a diamond layer bonded thereto. The diamond layer forms a dome-shaped cutting surface which is of symmetrical configuration about a center axis of the insert. A crest portion of the cutting surface has a larger radius of curvature than a peripheral portion thereof. The cutting surface can be formed by numerous radii, or can be of constantly varying radius (i.e., elliptical).Type: GrantFiled: August 18, 1997Date of Patent: September 14, 1999Assignee: Sandvik ABInventor: Karl Ingmarsson
