A drive shaft for transferring torque including a tubular insert extending along an axis and defining a first layer of the drive shaft including at least one straight portion and at least one undulation, wherein the tubular insert includes a first material having a first deformation temperature, and a polymeric tubular covering defining a second layer of the drive shaft surrounding the tubular insert including a second material having a deformation temperature lower than the deformation temperature of the first material, wherein the covering includes at least one straight portion adjacent to the straight portion of the tubular insert and at least one undulation adjacent to the at least one undulation of the tubular insert.

The present disclosure relates to insulation. Teachings thereof may be embodied in a solid insulation material, especially in tape form, the use thereof in a vacuum impregnation process and to an insulation system produced therewith, and also an electrical machine comprising the insulation system, especially for the medium- and high-voltage sector, namely for medium- and high-voltage machines, especially rotating electrical machines in the medium- and high-voltage sector, and to semifinished products for electrical switchgear. For example a solid insulation material with an anhydride-free impregnating agent may include: a carrier; a barrier material; a curing catalyst; and a tape adhesive. The curing catalyst and the tape adhesive are inert toward one another but react under the conditions of a vacuum impregnation process if combined with an anhydride-free impregnating agent having gelation times of 1 h to 15 h at impregnation temperature. The tape adhesive is free of oxirane groups and includes at least two free hydroxyl groups.

Various embodiments may include a solid insulation material, e.g. in tape form, the use thereof in a vacuum impregnation process, and/or an insulation system produced therewith and also an electrical machine having the insulation system, for the medium- and high-voltage sector. Some examples include rotating electrical machines in the medium- and high-voltage sector and also semifinished products for electrical switchgear. The solid insulation material and the insulation system produced therewith are characterized in that it can be produced in an anhydride-free manner, wherein the curing catalyst is, for example, an adduct of a 1H-imidazole and/or 1H-imidazole derivative with a compound containing oxirane groups.

A floor element for forming a floor covering, wherein the floor element comprises: a decorative layer made of a ceramic material; a support layer arranged below the decorative layer; and an intermediate layer comprising a rigid resin material that permeates a lower surface of the decorative layer, wherein the decorative layer is between 8 and 10 mm thick, wherein the support layer is made of rigid PVC, comprises more than 30 wt % of filler material and is less than 6 mm thick, and wherein the floor element comprises an intermediate reinforcing layer having a resin material that permeates a lower surface of the decorative layer, wherein the intermediate reinforcing layer is an adhesive layer that bonds together the decorative layer and the support layer.

A flexible flat cable (FFC) includes a first insulation layer, at least one pair of conductors, a plurality of low-k dielectric layers, two second insulation layers, and at least one shielding layer. The pair of conductors is located within the first insulation layer. Each pair of conductors includes a plurality of first conductors, and the first conductors are axially extending and arranged in parallel. The low-k dielectric layers are embedded in the first insulation layer. Each of the pair of conductors or each of the first conductors is covered and surrounded with one low-k dielectric layer. The two second insulation layers are located on two surfaces of the first insulation layer. The shielding layer is located on the two second insulation layers opposite to the first insulation layer.

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.
