Patent number: 7225050Abstract: A high-technology method for creating, reproducing, and or precisely fitting custom appendages to topographically complex structures. The method comprises a combination of novel measurement techniques in conjunction with computerized modeling and machining processes applied to achieve a virtually perfect tailored fit with mating structures. The method does not require the physical presence of the mating structure so the modeling and machining operations may be conducted at a separate location based solely on parametric dimensional and/or graphical data inputs and a customized data form. Said data may be transmitted conventionally or electronically as by fax or the internet. The invention includes a printed virtual protractor tool (16) for accurately measuring angles. A means for direct digitization of the required topological data input is also provided. The novel aspects of this invention can be combined with conventional fitting equipment and processes.Type: GrantFiled: January 4, 2002Date of Patent: May 29, 2007Inventor: Daniel P. Sutula, Jr.

Patent number: 5714712Abstract: A detonation system especially useful for initiating a plurality of substantially simultaneous seismic detonations includes an electric trunkline circuit disposed on the surface of a firing site containing boreholes, within which booster charges having respective top and base portions are disposed. The booster charges are connected without intervening detonators to the downhole ends of equal-sized lengths of low-energy detonating cord, the surface ends of which are connected to semiconductor bridge-initiated electric detonators connected in series in the firing circuit. The resulting system, because of the small deviation in function time of the semiconductor bridge detonators, has greatly reduced scatter time as compared to prior art systems utilizing conventional downhole electric detonators, and has a safety advantage in that the boreholes are free of detonators.Type: GrantFiled: October 25, 1996Date of Patent: February 3, 1998Assignee: The Ensign-Bickford CompanyInventors: David W.
