Patent number: 11446731Abstract: A support apparatus for supporting a steering rack forged in a forging die, comprising a gripper to grip the shank of the rack, a lost-motion mechanism supporting the gripper and permitting limited movement in the direction of closing of the forging die, and a side-shift mechanism to move the gripper sideways. The lost-motion mechanism abuts the die assembly as the forging die closes thereby positioning the gripper to grip the shank of the steering rack during the final closing travel of the forging die. The gripper then lifts the steering rack as the forging die opens. The side-shift mechanism then moves the gripped steering rack sideways.Type: GrantFiled: November 5, 2017Date of Patent: September 20, 2022Assignee: BISHOP STEERING TECHNOLOGY PTY LTDInventor: Wayne Bruce Cornish

Publication number: 20150219779Abstract: Seismic interpretation includes obtaining a seismic volume of a subterranean formation of a field. Through the seismic volume based on a similarity criterion of seismic values in the set of seismic traces, an estimated horizon is generated based on a selected seed while maintaining tracking data tracking the generating of the estimated horizon. A first selection of a selected point in the estimated horizon is received, and, from the tracking data, an ancestral path from the selected point to the selected seed is extracted. A subset of the set of seismic traces is selected based on the subset comprising points along the ancestral path, and displayed, within a graphic window on a physical display, the subset of the set of seismic traces.Type: ApplicationFiled: November 26, 2014Publication date: August 6, 2015Inventors: Zhenghan Deng, Bruce Cornish, Jay Vogt

Patent number: 8869582Abstract: A die apparatus for forging a steering rack having a toothed portion and an array of gear teeth. The die apparatus comprising first and second assemblies movable towards each other. The first assembly comprising a first bolster and a tooth die. The second assembly comprising a second bolster, first and second side dies, a center punch, and a third bolster. The third bolster being disposed between the first and second bolsters and being movable relative to the second bolster. The first and second side dies being supported by the third bolster, and the center punch being supported by the second bolster. As the die apparatus closes, the third bolster abuts the first assembly to form a closed forging cavity and then, as the die apparatus continues to close, the center punch penetrates the closed forging cavity to complete the forging of the steering rack.Type: GrantFiled: April 29, 2011Date of Patent: October 28, 2014Assignee: Bishop Steering Technology Pty LtdInventor: Wayne Bruce Cornish

Patent number: 8744564Abstract: A method of detecting tissue oedema in a subject. The method includes determining a measured impedance for first and second body segments. An index indicative of a ratio of the extra-cellular to intra-cellular fluid is then calculated for each body segment, with these being used to determine an index ratio based on the index for the first and second body segments. The index ratio can in turn be used to determine the presence, absence or degree of tissue oedema, for example by comparing the index ratio to a reference or previously determined index ratios.Type: GrantFiled: June 17, 2005Date of Patent: June 3, 2014Assignee: Impedimed LimitedInventors: Leigh Ward, Bruce Cornish

Publication number: 20120137747Abstract: A die apparatus for forging a steering rack from a bar. The die apparatus comprises a first and a second bolster movable towards each other, and at least one gripper adapted to grip the bar as the rack is forged. The gripper comprises first and second gripper halves carried by, and movable relative to, the first and second bolsters respectively. A gripper bias means biases the gripper halves towards each other. As the bolsters move towards each other to forge the rack, the first gripper half abuts against the first bolster, and the second gripper half abuts the second bolster.Type: ApplicationFiled: July 28, 2010Publication date: June 7, 2012Inventors: Wayne Bruce Cornish, Lyle John McLean

Publication number: 20060247543Abstract: A method and apparatus for the non-invasive measurement of cardiac function. A signal is applied between a pair of electrodes on a patient. The signal delivers a constant alternating current at multiple simultaneous frequencies. A second pair of electrodes measures a voltage signal. The impedance at each frequency is obtained by demodulating the current signal and the voltage signal using techniques such as Fast Fourier Transform (FFT). The FFT gives a phase and amplitude which is converted to an impedance value. The impedance values are fitted to a theoretical frequency dependent impedance locus and the locus is extrapolated to obtain a value at zero frequency. The steps are repeated to obtain a time-varying plot of impedance and measures of cardiac function are calculated from the time-varying plot.Type: ApplicationFiled: October 9, 2003Publication date: November 2, 2006Inventors: Bruce Cornish, Brian Thomas, Scott Chetham
