摘要:
A method for operating a data receiver for audio and/or video data, wherein a planned and variable program title sequence having program titles is recorded, audio and/or video data relating to at least one program title are received via a data link and are buffered, and audio and/or video data of at least one program title are reproduced. The transmission resources of the data link for audio and/or video data to be transmitted and to be buffered are distributed over at least two program titles that have not yet been reproduced by the data receiver. Also disclosed are a data receiver associated with the method and a media reproduction system connected thereto, in particular in a vehicle.
摘要:
An electric coupling for railways contains a first and a second coupling part (9) each comprising a support (16) in which a plurality of linking parts are arranged by means of which an electric, pneumatic and/or hydraulic link can be established from one coupling part to another coupling part. In addition, at least one high-frequency link (10) is provided which is formed by an enclosed antenna (20) in one coupling part and by an enclosed antenna (24) in the other coupling part.
摘要:
The present invention relates to high-quality polyurethane and polyurethane urea elastomers which exhibit unique combinations of processing characteristics, oxidation resistance, mechanical and mechanical/dynamic properties in particularly demanding applications. These polyurethane elastomers and polyurethane urea elastomers are based on novel polycarbonate polyols.
摘要:
A method and an apparatus for heating a sheet material made of an electrically conductive, non-magnetic material, the apparatus including at least one coil arrangement with DC-carrying windings that is made to rotate around an axis oriented perpendicular to the sheet material and to thereby induce eddy currents in the sheet material.
摘要:
The solar module according to the invention consists of a transparent adhesive layer (1), in which the solar cells (3) that are interconnected by cell connectors (2) are embedded. A transparent, UV stable, thin front layer (4), composed for example of a thin pane of glass, is located above said adhesive layer. The supporting sandwich element (5), consisting of a nucleic layer (6) and glass fibre layers (7) bonded by means of polyurethane is located on the rear face. Fastening elements (8) and an electric socket (9) are integrated into the supporting sandwich element. A barrier film (10), which prevents the entry of water and oxygen, adjoins the sandwich element. The solar module has peripheral edge protection (11) consisting of elastomeric polyurethane, which prevents the lateral penetration of water, dirt and oxygen. The invention also relates to a method for producing the solar module.
摘要:
The present invention relates to an antistatic or electrically conductive, thermoset polyurethane obtained by reacting A) an organic polyisocyanate; B) a compound comprising NCO-reactive groups; and C) optionally a catalyst, a blowing agent, an auxiliary, an additive, or mixtures thereof; and wherein, the polyurethane comprises a carbon nanotube present in an amount of from 0.1 to 15% by weight based on the total weight of the polyurethane.
摘要:
The present invention relates to a polyurethane coating having pipes or hoses having a diameter of ≦95% of the thickness of the polyurethane coating, through which a medium for heat exchange flows.
