  • Patent number: 10507779
    Abstract: A method for recognizing a usability of a control device of a safety device in a vehicle includes: applying a voltage to the control device; acquiring a voltage curve or a current curve at the control device; and recognizing a usability of the control device as a function of the acquired voltage curve or of the acquired current curve. In particular, the correct polarity of an inductive actuator having a freewheeling diode is recognized, because in the case of incorrect polarity the inductive actuator is bridged by the freewheeling diode.

  • Patent number: 10336274
    Abstract: A control unit for a restraint system in a vehicle, including an evaluation and control unit and at least one external ignition circuit interface to which a squib for activating the restraint system is connected via a go-line and a return line, the evaluation and control unit cyclically ascertaining, by measuring, an instantaneous ohmic loop resistance of the corresponding ignition circuit and comparing this with at least one stored threshold value. The evaluation and control unit determines an instantaneous temperature in the vehicle interior, close to the time for the measured value detection for ascertaining the ignition circuit loop resistance, the evaluation and control unit carrying out a temperature compensation of the ascertained ignition circuit loop resistance for the go-line and return line of the connected ignition circuit based on the instantaneous temperature in the vehicle interior, the go-line and return line being situated outside the control unit.

  • Publication number: 20190161355
    Abstract: A process for production of silica having variable thickening wherein a) a product stream I containing at least a vaporous, hydrolysable and/or oxidizable silicon compound, b) a product stream II containing oxygen and c) a product stream III containing at least a combustible gas are made to react, where d) a feed port in a pipepiece A, the pipepiece A containing one or more static mixing elements, is used to import product stream I into product stream II, or vice versa and thereby create product stream IV, then e) a feed port in a pipepiece B, the pipepiece B containing one or more static mixing elements, is used to import product stream III in product stream IV and thereby create product stream V, f) product stream V leaving pipepiece B is imported into a reaction chamber, ignited therein and reacted in a flame, and g) the resultant solid material is separated off.

  • Patent number: 9555230
    Abstract: A port for a catheter includes a housing, a chamber arranged in the housing for receiving a medically active substance, a connecting piece for connecting the catheter to produce a flow connection between the chamber and the catheter, and at least one lever, mounted to be pivotable about a pivot axis and realized to allow the catheter to be fitted onto the connecting piece in a first pivot position and to hold the catheter in a clamping manner on the connecting piece in a second pivot position. The at least one lever has different first and second portions. The first portion carries a latching device for latching the at least one lever with the housing and/or with a first portion of a further lever in the second pivot position. The second portion has a clamping device for holding the catheter in the clamping manner in the second pivot position.

  • Patent number: 8262629
    Abstract: The invention relates to a catheter port for supplying an active substance to an active site which is distant from the port. According to the invention, the housing (1) of the port is designed to have two parts, an upper housing part (7) and a lower housing part (6). The upper housing part (7) holds an insertion part (10) in a clamping manner in a housing recess (8) of the lower housing part (6), wherein a chamber (11) is arranged in said insertion part for receiving the active substance with the interpositioning of a punctured membrane (17) that can be pierced with an injection cannula. While the insertion part (10) and the chamber (11) can be manufactured from a material resistant to the active substance, preferably a heavier ceramics, the upper and lower housing parts may consist of a lighter biocompatible plastic material. It is advantageous that the patient only comes into contact with the upper and lower housing parts made of a biocompatible plastic material and not with the insertion part.

  • Publication number: 20100159167
    Abstract: The present invention relates to a polypropylene sheet having a peeling layer that is well-suited to bond detachably to coated or uncoated fibrous substrates. The peeling layer comprises a combination of polypropylene, preferably between 20% and 70%, and a polyolefinic plastomer having a density of 0.85 to 0.89 g/cm3, preferably between 30 and 80%, that meets this requirement without further additives such as bonding enhancers, inorganic fillers or polar polymers.

  • Patent number: 7533909
    Abstract: A tube connection device for connecting motor vehicle tubes, a tube having a front element on at least one end, this front element being equipped with a frontal sealing surface. A fitting enclosing the tube is provided, which presses the frontal sealing surface against a connection surface of a connection element. At least one separate pressure element, which at least partially surrounds the tube, is provided between fitting and front element. The fitting acts on the front element through the pressure element and the sealing surface is pressed against the connection surface in this way.
