| 69 | Surface safe explosive tool | US13847485 | 2013-03-20 | US08789467B2 | 2014-07-29 | Donald L. Crawford |

| 70 | Non-energetics based detonator | US13717970 | 2012-12-18 | US08661978B2 | 2014-03-04 | Roger F. Backhus; Richard W. Givens; Jerome A. Klein; Ronald L. Loeser; Jason E. Paugh; Walter G. VanCleave, III; Isaac Thomas Zimmer |
| A detonator system is provided for use with explosives that utilizes two subsystems. A first subsystem functions as a non-explosives based detonator, which does not contain any explosives. The second subsystem is an initiating subsystem, which includes an initiating pellet. To set off an explosive event, the non-energetics based detonator is coupled to the initiating subsystem and the non-energetics based detonator is commanded to provide a suitable signal to the initiating subsystem that is sufficient to function the initiating pellet. Further, the initiating subsystem can be integrated directly into an associated explosive such as a booster that has been configured to receive the initiator subsystem without changing the hazard class of the booster. | ||||||
| 71 | Blasting Method Using a Control Device for Inducing a Blast Pressure, and Control Device for Inducing the Blast Pressure to Apply the Method | US14000503 | 2012-02-17 | US20130319277A1 | 2013-12-05 | Geum Won Cho; Jong Eun Cho |
| The present invention relates to a blasting method using a control device for inducing a blast pressure, and a control device for inducing the blast pressure to apply the method. According to the blasting method using the control device for inducing the blast pressure, when a blasting operation is performed at the outermost hole of a tunnel or a wayside or wall surface of a structure constructed at a location in which an adjacent structure of a downtown area is located, a transfer path of the blast pressure is controlled using the control device for inducing the blast pressure so that the blast pressure does not exceed a proposed blast line, but is limitedly transferred into only a blasting area. Thus, a smooth and elegant blasted surface may be secured, and simultaneously, an over-break may be prevented and vibration and noises may be minimized. According to the present invention, since a general inexpensive explosive is loaded into a blasting prevention cover and easily utilized, the general inexpensive explosive may be replaced with an existing expensive precision explosive to significantly reduce blasting costs and improve blasting efficiency, thereby having a large economic impact and useful effects. | ||||||

| The disclosed device primarily consists of a band, ring, or other piece of shape memory polymer (SMP) or SMP composite in various embodiments that allows or disallows containment. When the SMP reaches its transition temperature (Tg) the SMP provides the means for releasing containment of the pressurized material so as to prevent ignition or explosion of hazardous material. At normal operating temperatures, the SMP is in a deformed shape maintaining an environmental seal to protect the contents of the container. When environmental conditions cause the SMP or SMP composite to exceed its Tg, specified by the operating requirements, the SMP returns to its memory shape in a controlled geometry, rather than simply melting. The return of the SMP to its memory shape causes the venting of the container in different manners depending on which embodiment is utilized. | ||||||
