Patent number: 9687902Abstract: A method of incremental autofrettage is taught herein, whereby the cycle life of a metal liner in a pressure vessel is increased. This method serves to increase the yield strength of the metal liner through sequential work hardening due to repeated autofrettage at increasing pressures. By incrementally increasing the internal pressure used in the autofrettage process, the compressive stresses at an inner surface of the metal liner may be controlled so that post-pressurization buckling does not occur, yet the yield strength of the metal liner is substantially increased. The higher compressive stresses in the metal liner mean that higher Maximum Expected Operating Pressures (MEOPs) may be used without detracting from the cycle life of the metal liner, or alternatively, for lower pressures, a longer metal liner cycle life may be obtained. Either internal or external pressures may be used, generated by a pressure source, or a suitable die.Type: GrantFiled: September 20, 2012Date of Patent: June 27, 2017Assignee: SPENCER COMPOSITES CORPORATIONInventors: Brian E.

Patent number: 9687916Abstract: A drill bit which is rotatable about a drilling axis is disclosed. The drill bit has a drill shaft section having a first plug-connecting element and a cutting section having a second plug-connecting element. The first plug-connecting element and the second plug-connecting element form a plug connection. The cutting section includes a plurality of cutting subsections each having a ring subsection and at least one cutting segment, wherein each ring subsection together with the first plug-connecting element forms the plug connection and is connectable to the first plug-connecting element by a pin connection.Type: GrantFiled: December 21, 2012Date of Patent: June 27, 2017Assignee: Hilti AktiengesellschaftInventors: Matthaeus Hoop, Christoph Weber, Joerg Ebert

Patent number: 9687917Abstract: A quick connect/disconnect mechanism for a rotary bit having a central mounting hole at a proximal end includes a shaft extending axially and having a proximal end adapted to be releasably secured in a rotary tool and a distal end having a spud extending distally and axially therefrom. A collet has a plurality of retainer arms arrayed circularly about the axis and extending distally, each retainer arm including a catch extending radially outwardly from a distal end thereof. A support ring extends about the shaft adjacent to said distal end thereof, the support ring being translatable from a first position in which the retainer arms extend freely distally and are deflectable sufficiently to be inserted through the central mounting hole of a rotary bit; to a second position in which the support ring and collet translate proximally and the spud extends distally to engage the retainer arms so they cannot deflect and release the rotary bit.Type: GrantFiled: November 1, 2013Date of Patent: June 27, 2017Inventor: Timothy Carl Pamatmat

Patent number: 9687920Abstract: Apparatus, methods, and other embodiments associated with a key duplication machine are described. In one embodiment, an assembly for duplicating a master key includes an optical imaging device, a logic, a clamping assembly, and a cutting member. The optical imaging device is capable of capturing an optical image of at least a portion of the master key. The logic is capable of determining a key pattern of the master key from the optical image of the master key. The clamping assembly is capable of clamping a key blank and the cutting member is capable of cutting a key pattern into said key blank.Type: GrantFiled: September 12, 2016Date of Patent: June 27, 2017Assignee: Hy-Ko Products CompanyInventors: Michael A. Bass, William R. Mutch, Richard W. Ryai, Sr., Chester O. D. Thompson, Robert E. Drake, Randall A. Porras

Patent number: 9687925Abstract: An electrolytic machining system includes a controller, a drive member coupled to the controller, a power supply, a diving circuit, a detecting circuit, and an electrode module. The diving circuit is coupled to the power supply module and configured to divide a total voltage taken from the power supply module into a plurality of independent working voltages. The detecting circuit is coupled to the dividing circuit and the electrode assembly. The detecting circuit detects each independent working voltage and feeds back information as to the level of the independent working voltage to the controller as the electrode assembly is moved towards a workpiece. When the detection indicates an incorrect working voltage, the controller controls the drive member to move the electrode assembly away from the workpiece.Type: GrantFiled: September 17, 2014Date of Patent: June 27, 2017Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: Shao-Han Chang
