Patent number: 7156023Abstract: When an ignition system is installed, the spatial position of an ignition device (5a to 5g) in relation to the surrounding, its geographical position, is as yet not determined. The user is required to exercise extreme caution in order to ensure that the ignition devices (5a to 5g) connect to the ignition system (1) in accordance with a predetermined blasting plan. A specially trained person must therefore systematically carry out the sequential connection (compulsory sequence) of each ignition device (5a to 5g) to the bus line (3) of the ignition system. i.e. logging. The person connecting the ignition devices must execute the ignition of device programming operation in all kinds of conditions, in open country, with utmost caution. This represents a considerable time delay for a blast. If one ignition device is overlooked during logging, the already entered data have to be reprogrammed, which costs time.Type: GrantFiled: April 18, 2001Date of Patent: January 2, 2007Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventors: Walter Aebi, Jan Petzold, Heinz Schäfer, Andreas Zemla

Patent number: 6945174Abstract: Errors may occur in a detonating system that consists of several detonating circuits when the connection—the logging-on—of detonators is effected to the buses of a logger which in turn is connected to a blaster. Connecting is effected, particularly in opencast-mining operations, under conditions that may lead to damage, not visible at first, in particular to the insulation of the detonators and also of the detonating lines. Errors may occur in the transmission of data, for example as a result of loss or falsification of the signals to be transmitted or as a result of intrusion of signals from an extraneous detonator. In accordance with the invention it is therefore proposed that a log-on manager is installed which is in bidirectional contact with the loggers, with the blaster and with the log-data communicators of the loggers which signal the data pertaining to the detonators to the logger.Type: GrantFiled: September 28, 2001Date of Patent: September 20, 2005Assignees: Dynamit Nobel GmbH Explosivstoff-und Systemtechnik, Teltronik AGInventors: Walter Aebi, Jan Petzold, Heinz Schafer, Andreas Zemla

Patent number: 6840772Abstract: The invention relates to a method for evaluating electronic impacts or shots of fired shots in a shooting range for sportsmen and for hunter training. The target to be shot at is provided as a light spot and is projected onto a target wall (1) via a light source in such a way that said target can move in all directions. An infrared camera (7) records the shooting image on the target wall (1) for evaluating the impact. The aim of the invention is to increase accuracy and reduce the evaluation time. Target co-ordinates arm detected while the target is being provided. Said target coordinates arm compared to the impact co-ordinates obtained by means of the impact evaluation. An impact is signalled when an impact falls short of a given divergence.Type: GrantFiled: April 22, 2000Date of Patent: January 11, 2005Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventor: Rudolf Pura

Patent number: 6637339Abstract: Effects of capacitive resistances on the transmission of data between electronic igniters of an ignition system and a device for programming and triggering igniters are avoided by the disclosed method. Prior to a planned communication of an igniter with the device, a dc voltage is applied to the ignition circuit for a predetermined length of time. This voltage is higher than the voltage provided for generating the signals with which the data are generated. Subsequently, the signals that the igniter transmits in response are produced with a lower voltage than the previously elevated voltage and the dc voltage is increased once again prior to the response to an additional igniter.Type: GrantFiled: January 23, 2002Date of Patent: October 28, 2003Assignee: Dynamit Nobel GmbH Explosivstoff und SystemtechnikInventors: Jan Petzold, Heinz Schäfer, Ulrich Steiner, Andreas Zemla

Patent number: 6601515Abstract: An igniter element has two contacts (12, 13) which are on the contact side of a support body (11), and which are connected via a resistance element (15). By current feed to the contacts (12, 13), a primer mix (17) is ignited on one active side of the support body (11). The support body (11) is placed in a fixing device (10), whereby the former is fitted with at least one stop spring (18) which catches on a stop shoulder (21) of the holding device. Furthermore, the support body (11) has a recess (22) on the front-side in the region of the stop spring (18), which recess is open in the direction of the active side. After igniting the primer mix (17), pressure builds up on the active side, so that the outer surface (23) of the stop spring (18) is pressed against the inner surface of the fixing device (10).Type: GrantFiled: August 11, 1999Date of Patent: August 5, 2003Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventors: Anton Bretfeld, Harald Frank, Jiang Zhang

Patent number: 6601514Abstract: The invention relates to an ignition unit (1) suitable for triggering an active system, such as an airbag or safety belt. The ignition unit comprises an ignition charge (7) located in a housing (2), which can be fired by means of an ignition bridge (6) positioned on a support element (5), as well as at least one contact pin (13a, 13b, 13c) which protrudes from the housing (2) and via an electronic ignition system (9) is electrically connected to the ignition bridge (6). The electronic ignition system (9) is surrounded by an envelope (10) made of a shock-absorbing material. The ignition bridge (6) is not covered by the envelope (10) so that during ignition the pressure exerted on the electronic ignition system (9) is cushioned. This prevents damage to the sensitive electronic components of the electronic ignition system (9) situated on the support element (5).Type: GrantFiled: July 5, 2001Date of Patent: August 5, 2003Assignees: Dynamit Nobel GmbH Explosivstoff-und Systemtechnik, Temic Telefunken Microelectric GmbH, TRW Airbag Systems GmbH & Co., KG, Unax AGInventors: Anton Bretfeld, Gerhard Kordel, Horst Laucht, Erwin Caflisch, Richard Baur, Michael Bischoff, Gunter Fendt, Stefan Schwehr

Patent number: 6499404Abstract: In ignition elements where the energy required to ignite the charge is produced using a laser source, the laser light is injected by means of an optical fiber or a laser optics system enabling the laser light to be focused onto the charge at the required intensity for ignition. Transmission losses and injection losses occur while the laser light is transmitted by means of optical devices or optical fibers. Known ignition devices are also complicated in terms of construction. According to the invention, the laser light source is a laser diode (3) and the explosive (4) that is to be ignited is arranged directly on the part (12) of the housing (8) of the laser diode (3) that allows the laser light (13) to pass through it.Type: GrantFiled: April 13, 2001Date of Patent: December 31, 2002Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventors: Heinz Kern, Gerhard Kordel

Patent number: 6488231Abstract: The invention relates to a missile guidance method, more particularly for anti-armor projectiles fired directly at a target. In order to avoid missing a target by a narrow margin, the invention provides that the distance to the target (3) be measured with a range finder (8) before the projectile is fired. The flying time previously calculated on the basis of target distance is inputted to the projectile (1). The projectile (1) has one or several sensors which are activated after a predetermined flying time, said sensor or sensors determining whether the projectile (1) will fly over the target at a minimum distance. Optionally, the projectile (1) conducts a single trajectory adjustment with a fixed value.Type: GrantFiled: February 16, 2001Date of Patent: December 3, 2002Assignee: Dynamit Nobel GmbH Explosivstoff-und SystemtechnikInventor: Rainer Schoffl
