| 20090001709 | Multi-Ply Security Paper - The present invention relates to multi-ply security paper for manufacturing security or value documents, such as banknotes, identification cards and the like. Into a first paper ply ( | 01-01-2009 |
| 20100065639 | SECURITY ELEMENT FOR PROTECTING DOCUMENTS OF VALUE - The invention relates to a security element for protecting documents of value, which has magnetic material. A portion of a magnetic coding is arranged on the security element, which coding consists of several magnetic areas and several gap areas. The portion of the magnetic coding is arranged in a predetermined direction along the security element, for example perpendicularly to a transport direction of the security element or document of value through a magnet sensor. Concerning the length of the magnetic areas and of the gap areas of the magnetic coding, certain length conditions are predetermined, which are chosen in dependence on the magnet sensor employed. | 03-18-2010 |
| 20100219245 | SECURITY ELEMENT FOR SECURING DOCUMENTS OF VALUE - The invention relates to a security element for securing documents of value. Along the security element a portion of a magnetic coding with first and second coding elements is arranged. The coding elements are arranged along a predetermined direction, wherein the first coding element continuously has along the predetermined direction a first magnetic region with a first coercive field strength and the second coding element has at least one first gap region and one second magnetic region with a second coercive field strength. At least one of the first magnetic regions is directly adjacent to at least one of the second magnetic regions. The sum of the lengths of the directly adjacent first and second magnetic regions amounts to a maximum of 8 mm. | 09-02-2010 |

| 20090045763 | Method and Arrangement For Monitoring Signals - The invention relates to a method and to an arrangement for monitoring signals which are guided to a multi-phase motor by an end stage and the pulse width thereof is controlled by a controller. The total of the pulse widths of the signals of each phase is measured by, respectively, a counter, respectively for a predetermined programme flow in the controller. The meter reading is read by a counter according to a predetermined period of time and an error signal is produced if the total amount of time exceeds a predetermined tolerance range. | 02-19-2009 |

| 20110095071 | METHOD FOR POSITIONING TWO COMPONENTS USING TACK WELDS CROSSING THE JOINT LINE - The invention relates to a method for positioning two components to be joined to each other along a common joint line. According to the invention, the two components are connected to each other by limited-length tack welds firmly connecting the two components, particularly by way of bonding, to each other. In order to obtain reliable and robust positioning of the components for tacking during the joining process, without requiring extensive production apparatuses, such as is required for the high-precision setting of the focal point of the welding laser relative to the joint line, the tack welds are designed such that they cross the joint line. | 04-28-2011 |

| 20080209742 | Reciprocatory saw and more especially a jigsaw - A reciprocatory saw and in particular a jigsaw comprises a pitman with a chuck means arranged for the releasable clamping of a saw blade. The chuck means comprises a movably mounted chuck jaw arrangement able to be clamped laterally against the saw blade shank, a wedge element arrangement adjacent to and for cooperation with the chuck means, a first spring means whose spring force acts downwardly on the inserted saw blade and a second spring means whose spring force acts on the wedge element arrangement downward. The wedge element arrangement is connected with the chuck jaw arrangement in a manner for the transmission of rotary movement and from the outside and is able to be shifted between a bottom clamping position clamping the chuck jaw arrangement against the saw blade shank and a top release position freeing the chuck jaw arrangement. The wedge element arrangement assumes an angular position turned in relation to the clamping position and is seated on a stationary holding face. Furthermore there is a stationary abutment face associated with an abutment arrangement on the saw blade shank so that in the clamping position the abutment arrangement is held by the first spring means against the abutment face and in the turned release position of the wedge element arrangement and the chuck jaw arrangement the shank may be moved beyond the abutment face. | 09-04-2008 |
