20090013762 | Apparatus for estimating residual life of blasting vessel, method of estimating residual life, and blasting facility - The present invention aims at estimating a residual life of a blasting vessel. For the estimation, a strain gauge | 01-15-2009 |
20100229633 | Spot Test Kit For Explosives Detection - An explosion tester system comprising a body, a lateral flow membrane swab unit adapted to be removeably connected to the body, a first explosives detecting reagent, a first reagent holder and dispenser operatively connected to the body, the first reagent holder and dispenser containing the first explosives detecting reagent and positioned to deliver the first explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body, a second explosives detecting reagent, and a second reagent holder and dispenser operatively connected to the body, the second reagent holder and dispenser containing the second explosives detecting reagent and positioned to deliver the second explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body. | 09-16-2010 |
20100275676 | PASSIVE BLAST PRESSURE SENSOR - A passive blast pressure sensor for detecting blast overpressures of at least a predetermined minimum threshold pressure. The blast pressure sensor includes a piston-cylinder arrangement with one end of the piston having a detection surface exposed to a blast event monitored medium through one end of the cylinder and the other end of the piston having a striker surface positioned to impact a contact stress sensitive film that is positioned against a strike surface of a rigid body, such as a backing plate. The contact stress sensitive film is of a type which changes color in response to at least a predetermined minimum contact stress which is defined as a product of the predetermined minimum threshold pressure and an amplification factor of the piston. In this manner, a color change in the film arising from impact of the piston accelerated by a blast event provides visual indication that a blast overpressure encountered from the blast event was not less than the predetermined minimum threshold pressure. | 11-04-2010 |
20150143875 | Blast Exposure Recording Device - A blast pressure recording device and method includes at least one first sensor for measuring a parameter indicative of a blast event, at least one comparator in communication with the at least one first sensor for determining whether said parameter indicative of a blast event exceeds a predetermined threshold, at least one second sensor for measuring blast pressure, a power control means providing power to the at least one second sensor only when the predetermined threshold is exceeded, and a controller for receiving and recording blast pressure. | 05-28-2015 |
20160123914 | DETONATOR SYSTEM CONFIRMATION - A signal is injected into a wired series of detonators to obtain a reflected signal which represents a validated status of the system. The reflected signal is compared to a second reflected signal, generated in a similar way, some time later; to detect factors which affect the validated status of the system. | 05-05-2016 |

20160097756 | SYSTEMS AND METHODS FOR MAPPING AN EXPLOSIVE EVENT - Systems and methods for mapping an explosive event are discussed. In an example, a system for mapping an explosive event can include a plurality of sensor devices and a data analysis system. Each of the plurality of sensor devices can include an environmental sensor to measure at least one parameter of an explosive event. Each sensor device can also include a time synchronization circuit to synchronize time stamping of the parameter measured by the environmental sensor, and a wireless communication interface. The data analysis system can access measurement data generated by the plurality of sensor devices and analyze the measurement data to produce a visualization mapping the measurements onto a virtual representation of the test environment. | 04-07-2016 |

20090217739 | METHOD FOR THE DEVELOPMENT AND QUALITY CONTROL OF FLOW-OPTIMIZED SHAPED CHARGES - An improved test setup facility, referred to as a “Quick Development Cell” (QDC), which allows for rapid turnaround testing with valuable feedback to a design engineer. Because the QDC allows for quick and efficient testing at a sufficient frequency, QDC tests are compatible with production quality control. In addition to fostering improvement of the API's Section 2 type tests using stressed natural rock for benchmark experiments, the QDC tests allow for progress to be made towards the development of a flow-optimized shape charge and superior well performance. | 09-03-2009 |
20100294023 | Propellant Ignition Testing Apparatus Having a Compressively Sealable Chamber - A propellant ignition testing apparatus having a compressively sealable chamber. A fixed end plate assembly is fixedly mounted on a support structure. A test chamber assembly having a combustion chamber for accommodating propellant is provided, and an initiator ignites propellant accommodated in the combustion chamber. A moveable end plate is disposed adjacent to the test chamber assembly on a side thereof remote from the fixed end plate assembly. A device is mounted on the support structure for generating a compressive force, with the moveable end plate being operatively connected to a moveable component of the device for moving the moveable end plate toward the test chamber assembly for sandwiching the combustion chamber of the test chamber assembly in a compressively sealed manner between the fixed end plate assembly and the moveable end plate. | 11-25-2010 |
