  • Patent number: 11066346
    Abstract: The invention relates to a method (100, 200) of obtaining one or more olefins, in which, using an oxidative coupling of methane (10), a gas mixture comprising hydrogen, methane, carbon monoxide and higher-boiling hydrocarbons than methane is formed and is subjected to a low-temperature separation (1-5), characterized in that the low-temperature separation (1-5) is conducted using a rectification column (2) having a first separation region (21), a second separation region (22) arranged above the first separation region (21), and a condenser-evaporator (23), wherein the gas mixture is cooled, fed at least partly as first separation feed into the first separation region (21) and subjected to a first rectification in the first separation region (21) to form a first tops gas and a first bottoms liquid, wherein, using a first proportion of the first tops gas in the condenser-evaporator (23), a condensate which is recycled to the first separation region and, using a second proportion of the tops gas, a second separa

  • Patent number: 10919205
    Abstract: A method for producing an elongated product. By an extrusion unit, a material is extruded onto a core of the elongated product as a casing having a predetermined wall strength. Downstream of the extrusion unit and while the material is still moldable, the elongated product is supplied in a conveying direction to a molding unit. A portion of the material is held by the molding unit and, from the held material, a molded part is formed in an integral manner on the casing. The formation of the molded part is thereby carried out in an advantageous manner, via a deformation of material of the casing.

  • Patent number: 10483021
    Abstract: A cable is specified, specifically for a signal line, which extends in a longitudinal direction and which includes an inner conductor and also an outer conductor. Between the inner conductor and the outer conductor there is formed an insulating material which surrounds the inner conductor and which has a surface that has been at least partially carbonized. Furthermore, a production method for such a line is specified.

  • Publication number: 20190344488
    Abstract: A method for producing an elongated article with a sheath. The sheath is extruded with a predetermined wall thickness in an extrusion unit. Following the extrusion unit in a feeding direction, a part of the still moldable material is built up with the aid of a molding unit during a molding process such that a molded part forms integrally on the sheath. The molding unit is moved according to the following working cycle: the molding unit is accelerated from a starting position in the feeding direction, then it is advanced in the direction of the elongated article and the molded part is formed, the molding unit is withdrawn from the elongated article, and the molding unit is decelerated and moved from an end position, counter to the feeding direction, back in the direction of the starting position.

  • Patent number: 10436995
    Abstract: A cable, which extends in a longitudinal direction, has a cable core and a cable jacket. The cable jacket is extruded around the cable core. The cable is distinguished by the fact that the cable jacket has a plurality of chambers and, overall, is designed, in particular, in the manner of a hollow profile, and by the fact that a functional material different from the material of the cable jacket is introduced within at least one of the chambers. The functional material is preferably a flame proofing agent, but numerous other materials and, in general, functional elements are also conceivable. We further describe a method for producing the cable.

  • Publication number: 20180158572
    Abstract: A heavy-current cable, in particular a charging cable, has an outer jacket, a number of heavy-current cores which extend in the longitudinal direction, and at least one cooling jacket with at least one hollow chamber extending in the longitudinal direction for conducting a coolant. A power supply system, in particular a charging system for a hybrid or electric vehicle, has such a corresponding heavy-current cable.

  • Publication number: 20180042071
    Abstract: A heatable media guide serves for guiding a medium. It has a tubular guide element which extends in a longitudinal direction and has a sheathing made from a sheathing material, which surrounds an interior space for the medium. The guide element furthermore has at least one heating element, which extends with the sheathing in the longitudinal direction and which is embedded in the sheathing material.

  • Publication number: 20160343471
    Abstract: An electrical cable contains a cable bundle formed by at least two single wires, each containing a conductor surrounded by insulation. An adhesive layer is applied to all single wires, surrounding the insulator in a ring-like manner, via which the single wires are adhered to one another. The cable bundle does not also contain a cable sheath surrounding the cable bundle. The adhesive layer is formed by a reactive coating that is cured after activation so that a thermally stable connection can be achieved. The cable bundle is formed by single wires that are twisted with one another, and which are used, as a data line. This structure, with the adhesive layer, removes the need for a cable sheath so that a more compact structure can be achieved. The form lay length of the cable bundle is fixed, having a positive effect on the transmission characteristics for a data line.

  • Publication number: 20080093937
    Abstract: An electrical machine, preferably a blower drive mechanism for a motor vehicle, having a shaft which is supported in at least two bearings with a specified axial play; a cylindrical bearing is secured in a bearing seat of an end shield and rests directly on the bearing seat. The cylindrical bearing has a cylindrical outer circumference, and the bearing seat is a sleeve with a cylindrical inside diameter, into which sleeve the cylindrical bearing is secured with a press fit on the outer circumference and is held axially in the bearing seat by the thus-attained frictional engagement. This has the advantage that more-precise adjustment of the longitudinal play of the armature is possible. Moreover, no additional components such as retaining springs are necessary.

  • Patent number: 5706784
    Abstract: A method and a device for controlling the exhaust temperature for a combustion engine with knock control by varying the air/fuel mixture supplied to the engine as a function of ignition-retard settings to prevent knocking, as are undertaken by a knock-control device, an increasingly retarded ignition (setting) entailing increasing enrichment; the procedure is such that a cylinder-selective enrichment follows in dependence upon the momentary ignition-retard (setting) in a cylinder.

  • Patent number: 4102117
    Abstract: A twisted pair of wires is produced by drawing two insulated wires from two supply reels while rotating one wire supply reel about the other. A capstan and tachometer measure the linear rate at which the twisted pair is being drawn. The output of the tachometer is controllably and variably divided and used to control a power inverter that drives a motor which rotates the one wire supply reel about the other. The variable ratio between the linear wire movement and the rotary or twisting movement is controlled by a random generator producing a series of numbers representing length per twist of the twisted pair, between fixed limits.
