Device for the contactless transfer of electrical energy

A device is described with which electrical energy can be transferred from a power cable running along a stationary rail of a transport system to a moving element that can be driven along the rail. Each moving element has for this purpose a transfer head which works inductively together with the power cable. The power cable is attached with the aid of carrier profile which extends substantially along the entire length of the rail and is fixed in a releasable manner to the rail, which element has at least one a trough-like holder open to the side in which the power cable is laid. The power cable is thus relatively easily and accurately laid, avoiding hanging loops of cable which could be damaged by abrasion by the passing transfer heads of the moving elements.

Method for the Production of Structural Components from Fiber-Reinforced Thermoplastic Material

Abstract of the DisclosureThe method enables the series production of light structural components out of long-fiber thermoplastic material (LFT) with integrated continuous fiber (CF) - reinforcements in a single stage LFT - pressing step. In this, CF - tapes (5) are melted open and transferred into a profile tool (21) of a CF - profile forming station (20), there are pressed for a short time period and shaped into the required CF - profile (10). In doing so, by means of contact with the thermally conditioned profile tool (21) on the profile surface (11) a shock-cooled, dimensionally stable, thin casing layer (12) is formed and the inside of the CF - profile remains melted. Following a defined short shock-cooling period (ts), the CF - profile (10) is transferred into an LFT - tool (31) and pressed together with an introduced molten LFT - mass (6). In doing so, the casing layer (12) is melted open again on the surface (11) and is thermoplastically bonded together with the surrounding LFT - mass.
