Abstract: A detonator positioning device for use with a detonator in a perforating gun assembly is described. The detonator positioning device may be configured for electrically contactably forming an electrical connection within the perforating gun housing by contact. The detonator positioning device may include a body having a first end, a second end, and a central bore extending between the first and second ends. The central bore may be adapted for receiving one or more electrically contactable components of a detonator. The detonator positioning device can align at least one of the one or more electrically contactable components to form an electrical connection with a bulkhead assembly.

Abstract: A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.

Abstract: A processing unit includes a first communication interface that is designed for communication with a server device and/or a mobile device. The processing unit also has a second communication interface, which is designed for communication with the mobile device. The processing unit further has an internal communication interface of the processing unit, which is designed for communication with a vehicle bus network of the vehicle. The processing unit is designed to receive vehicle access data, which is representative of an access authorization of a driver to the vehicle via the second communication interface. The processing unit is also designed to determine depending on the vehicle access data a release signal for enabling a use of the vehicle and to provide it to the internal communication interface. The processing unit is also designed to receive vehicle analysis data via the internal communication interface.

Abstract: In order to determine the conversion efficiency of at least one component of a catalytic converter box comprising at least one SCR catalytic converter and an oxides of nitrogen storage catalytic converter for the aftertreatment of the exhaust gases of an internal combustion engine, wherein the catalytic converter box is associated at the downstream end with a NOx sensor, at least for a limited period of time the internal combustion engine is operated such that a first of the two components does not affect the signal detected by means of the NOx sensor and the conversion efficiency of the second component is determined depending on the signal of the NOx sensor that is not affected by the first component.

Abstract: The invention relates to a system for the automatic, rapid and dynamic conveyance of biological cells for transplant, therapy or research purposes between withdrawal centres or banks (storage facilities) and clinics, transplant centres or research facilities and also for the monitaring and backing of the processes from request transmission, for supply of a cell specimen which is suitable for the allogeneic transplant, through application of the conveyed specimens to tracking of the results in a patient and the provision of these data for statistical and other purposes. For the first time, the system is able to put forward complete solution proposals for specifically stored transplants online and automatically.

Abstract: A method for operating an internal combustion engine, injects fuel directly into a combustion chamber as a main injection, a postinjection and optionally also as a preinjection. An injection nozzle with a plurality of injection bores effects the preinjection and the postinjection preferably which is carried out cyclically. To minimize wetting of the combustion chamber walls, during the postinjection the partial quantities of fuel and a lift of the nozzle needle of the injection nozzle are set so that, for each partial quantity of the postinjection injected into the combustion chamber, the reach of the respective fuel jet in the combustion chamber is limited and the reach is less than the distance to a combustion chamber boundary.

Abstract: The invention relates to an internal combustion engine with a fuel injection device with an injection nozzle having a nozzle needle and a plurality of injection bores. The injection nozzle is arranged to inject fuel into the combustion space in the form of a plurality of fuel jets as a main injection, as a post-injection and/or a preinjection. The injection bores of the injection nozzle are arranged in at least two different separately activatable rows of holes, an operating stroke of the nozzle needle being set by control unit as a function of a piston position and/or an operating point of the engine, and the rows of holes of the injection nozzle different injection-hole cone angles.

Abstract: A fuel dispenser seal to be used in an inlet of a fuel tank having an orifice of a reduced diameter. The seal comprises a sealing ring made of a polymer material which is provided with a sealing lip which can engage with the fuel dispenser. The sealing ring is held in a support body of a basically tube-like shape and in at least a partial section the support body is elastically configured and can be inserted into the inlet through orifice by a reversible diameter reduction. In the inlet it can engage with a projection of the inlet facing in radial direction towards the interior and it can be firmly attached in axial direction.

Abstract: A louver for selectively closing flow openings defined therethrough comprising a stationary support grid including a plurality of equidistantly spaced, first rods extending in a first direction to define flow openings therebetween, a movable grid including a plurality of spaced, second rods extending parallel to the first rods and being movable relative to the first rods in a second direction perpendicular to the first direction from a first position in which each of the second rods at least partially overlaps a respective one of the first rods to a second position spaced from said first position by a distance approximately equal to the equidistant spacing between said first rods and a plurality of substantially impermeable, flexible, flat structures each having first and second longitudinal edges and each of which is connected along the entire length of its first edge to one of the first rods and along the entire length of its second edge to a respective second rod that at least partially overlaps said one f

Abstract: A key telephone system has output circuits connectable to a plurality of outside lines which are connected to a central exchange. A wireless telephone having a base unit with first and second output terminals and a separable cooperating handset unit having a manually operable number entry device is associated with the system. These units have cooperating radio transmitters and receivers which permit wireless communication links to be established between the units. A cordless telephone-key telephone interconnection interface has first and second output terminals respectively connected to the first and second output terminals of the base unit and output terminals connected to the output circuits of the key system. The interface establishes a plurality of calling numbers for the outside lines to be employed by a user of the handset unit.
