5. WOWO/2014/056491 - CAGE FOR A ROLLING BEARING AND METHOD FOR THE PRODUCTION THEREOF17.04.2014
F16C 33/44
PCT/DE2013/200081SCHAEFFLER TECHNOLOGIES AG & CO. KGLAUGISCH, Gabriele
The invention relates to a method for producing a cage for a rolling bearing, wherein the cage has a body made of a cured fibre-reinforced resin matrix and wherein pockets for receiving rolling elements are formed in the body, the method comprising the step: winding the resin-wetted fibres (2) around a winding mandrel (1). The problem of specifying a method for producing a cage made of a cured fibre-reinforced resin matrix, wherein the cage is better suited for high rotational speeds, is solved according to the method of the invention in that placeholders (4, 4') are arranged on the winding mandrel (1) at the positions of the pockets, and the fibres (2) are run past the placeholders (4, 4').

6. WOWO/2014/056472 - DIELECTRIC ROLL ACTUATOR17.04.2014
H01L 41/053
PCT/DE2013/000555HOCHSCHULE OSTWESTFALEN-LIPPEGRAF, Christian
The invention relates to a cylindrical, dielectric roll actuator (10) having an axial displacement. In an unloaded state a core (9) of round cross-section that is deformable under load is provided, to which under axial prestress a winding made of a stretched film composite (8) is spirally applied. The film composite comprises a polymer film (1) made of an electroactive polymer having at least two electrodes (2, 3) electrically separated by the polymer film (1), and a further electrically insulating polymer film (7). For the purpose of applying the film composite, an axial central opening (24) in the core (21) can be penetrated by a rod (22) on which the core (21) is axially prestressed, and then the film composite (18) is wound onto the axially prestressed core (21).

7. WOWO/2014/056487 - SCALABLE, HIGHLY DYNAMIC ELECTROMAGNETIC LINEAR DRIVE WITH LIMITED TRAVEL AND LOW TRANSVERSE FORCES17.04.2014
PCT/DE2013/100352RHEFOR GBRMECKLENBURG, Arno
A scalable, highly dynamic electromagnetic linear drive with limited travel is described below. The linear actuator is distinguished by low transverse forces. According to an example of the invention, the linear actuator comprises the following: - a stator comprising two soft-magnetic limbs; - an armature made of soft-magnetic material which is flat at least in certain sections and which is arranged so as to be movable along an axis between the limbs of the stator; - at least two flat coils with a soft-magnetic core and a large coil height, which coils are attached to the stator (stator coils), wherein the coil cores are part of the soft-magnetic limbs or are connected thereto in a magnetically conductive fashion; - at least one flat coil (armature coil) with a soft-magnetic core and a large coil height which is attached to the armature, wherein the coil core can be part of the armature or can be formed therefrom, or the armature coil is located with its soft-magnetic core lying in a recess in the flat armature; - a well-defined start and end position of the travel ("end positions") - at least one switchable means which is designed to lock the armature in at least one end position counter to a restoring force, for example a self-locking magnet or a mechanical latch, - a switchable power supply composed of an energy accumulator, for example a capacitor battery, and at least one switch.
